Description

The modules are the main component of photovoltaic installations, besides having to produce energy for more than 25 years, must withstand the most severe atmospheric variations.

 

Virtually no industrial product has to withstand these harsh conditions for so long. This is the reason why extreme care for quality of each and every one of the components used in its construction and strive to the different production processes, with multiple and rigorous quality controls to give confidence to our customers during its lifetime.

 

Our PV modules are designed with the latest materials that provide strength and excellent sealing qualities of impermeability and supporting its long life, allowing seamless operation of the system even in the harshest weather conditions.

 

They are made with crystalline silicon cells (mono or poly) guaranteeing the electricity production from sunrise to sunset.

 

All models have junction box resistant to weathering, with positive and negative terminals incorporating bypass diodes (by-pass) whose mission is to prevent the possibility of breaking the electric circuit within the module by partial shading of the cells.

 

The wide range of existing powers, ensures all the needs of use in photovoltaic solar systems.

 Materials

Solar Innova uses the latest materials to manufacture solar photovoltaic modules:

 

Glass

The front of the module contains a tempered solar glass with high transparency with high transmissivity, low reflectivity and low iron content.

 

The glass forms the front end of photovoltaic module and protects components housed within the laminate from the weather and mechanical stresses.

 

At the same time serves as carrier material in the lamination process.

 

A high transmittance increases the efficiency of the photovoltaic cells and thus has a direct influence on the potency and performance of the final module. A low iron content in the glass composition and an antireflection coating to reduce absorption of radiant energy.

 

Achieve excellent resistance against mechanical stress and temperature changes due to preload producer.

 

Anti-reflective Coating

 

Low-iron solar glass, combined with nanometer anti-reflective coating technology, is applied for solar modules. It increases solar transmittance by way of decreasing light reflectance, thus increasing the solar cell efficiency. Besides, it reduces the reflected glare of the glass and the pollution caused by the reflectance to the environment. The super water-wet behavior of the coating could in some degree protect the dust and dirt from shading the light and improve the self-cleaning of the glass so that the solar cell could maintain high efficiency.

Top Encapsulant (EVA)

The sheets of EVA (Ethyl Vinyl Acetate) are used to connect the solar cells through the lamination process with glass surface. This step provides the "encapsulated" solar module that is responsible for holding together the photovoltaic module and have a decisive bearing on life. The degree of chained EVA sheet after the lamination process is decisive for the quality indicator of the solar module.

 

An EVA sheet must guarantee insulation and protective effect throughout the life of the module. The films of poor quality can cause long-term discoloration, delamination or decomposition and, therefore, strongly impair the performance capability of the module in question. Solar Innova uses only high quality sheet of chains with a degree exceeding 85%, thus providing long lasting protection of cells.

Ribbon

Welding ribbon is specially designed for manufacturing solar panels product. It is used for electrical connections between solar photovoltaics.

 

It is made with a flat copper tape, coated with a thin layer of tin (414-600 microinches) on all sides. Tin copper confers protection against oxidation and provides a layer for easy welding.

 

The welding of the cells is performed by a combination of heat and pressure welding the longitudinal straps. The tape reaches the factory coils are placed in the automatic welding machines.

 

The solder coating on the ribbon interconnect provides 100% of that needed to form a reliable metallurgical bond at the top of the welding cells.

Cells

Solar cells directly convert sunlight into direct current electrical energy and the generator are of the module. The quality of cells directly influences the characteristics of a solar module is therefore essential silicon composition used.

 

Solar Innova cells used exclusively Innova highly efficient with minimal variations in the process of optimizing the production reproducibility of the separation of cells. Is a determining factor for the quality of the cell constant for stable profits. The high resistance multipliers and fill factors used cells provide a good source of energy radiation especially low.

 

Each cell is checked, and classified electrically calibrated prior to interconnection to optimize the behavior of the module.

Back-Sheet (TPT)

TPT backsheet is composed of a plastic polymer trilayer laminated between two layers of polyester sheet of Tedlar. Provides complete protection and sealed against environmental agents and offers a perfect electrical insulation due to its excellent strength and barrier properties against moisture and UV resistance. It also reduces the operating temperature of the cells.

Junction Box

The primary function is to transmit the energy produced in the module.

 

The junction box installed is made high temperature resistant plastics. The box is sealed and ready for the weather. Has a degree IP-65, which provides the insulation system against moisture, inclement weather, dirt and ultraviolet radiation. Inside are installed bypass diodes.

 

Bypass diodes protect the tensile modulus increased and consequently the so-called hot spot effects.

 

The modules are supplied with box and bypass diodes integrated.

 

In each module there is a single box for both terminals. Polarity must be observed in the connections to the proper functioning of the modules.

 

The junction box can be opened in case of failure, thereby facilitating an eventual replacement of damaged diodes. Covers of junction boxes have an indicative drawing. They open by inserting a screwdriver in the appropriate tab in the direction of the arrow, with light pressure on it to open. To close the lid, simply press it to closure. The lid has a flange attached to the junction box while handling the interior thereof. This flange must not be cut at all.

 

The junction boxes should not suffer any pressure when installing the module on a support structure. No element of it should touch the box.

 

The junction boxes are similar to modules with the same voltage rating. All connection boxes are provided with symmetrical cables of length 900 mm with a connector positive (+) and a negative connector (-) with a working temperature range between - 40 ~ + 85° C.

Protection Diodes

The shading of a cell can cause a reverse voltage on it. This cell thus consume power generated by the other in series, resulting in undesirable heating of the shaded cell. This effect, called hot spot will be greater the higher the radiation incident on the rest of the smaller cells and cell receiving that due to the shadow. In an extreme case the cell may be broken due to overheating.

 

The use of protective diodes or by-pass reduces the risk of heating of the shaded cells, limiting the current that can flow through them and thus preventing the breakage thereof.

 

All modules with a number of cells greater than or equal to 33 connected in series, manufactured by Solar Innova, are provided with protection diodes that are located at the junction boxes. In modules with fewer cells in series are not required the bypass diodes, as the hot spot effect does not reach the level of risk of rupture of the cells.

 

The replacement of bypass diodes should be performed only by a qualified competent photovoltaic after disconnecting the system module.

Cables

Our modules are fitted with flexible cables, symmetrical in length, with a diameter of copper section of 4 mm, weather resistant and have been specially designed and certified for use in our modules. Have high values ​​of electrical safety and fire resistance. Its insulation to weathering and UV rays ensures longevity of the installation. Furthermore, the wide range of temperature allows its application even in extreme climatic areas, preventing heat aging and therefore allowing a long life in the photovoltaic system. They have a high strength and a very low contact resistance, all designed to obtain minimum voltage drop losses and allows them to continue operating even in unfavorable conditions.

 

All our photovoltaic modules are supplied with cable assemblies in the box with the following features:

  • Length: 900 mm

  • Operating Temperature Range: - 40 ~ + 90° C

Connectors

Our PV modules are equipped with connectors and sockets MC-T4 100 % compatible with the connectors and sockets used to connect electrical systems. Only MC-T4 connector or compatible and special solar cables may be used to lengthen the cables connected to the module. These must meet the electrical requirements of the Interconnection design.

 

All our photovoltaic modules are supplied with assembled connectors on cables with the following features:

  • Diameter: Ø 4 mm

  • Maximum rated current: 30 A

  • Maximum system voltage: 1000 V

  • Plugged Protection level: IP-67

  • Mounting: easy

  • Locking system: Snap in

  • Protection Class: II

  • Operating Temperature Range: - 40 ~ + 90° C

Frame

Our modules are completed self-supporting compact frame made of aluminum anodized aluminum pressure 5 series to achieve an optimum weight moment of inertia, in order to obtain greater rigidity and resistance to torsion and bending. This variant consists entirely of aluminum frame provides maximum stability and protects the materials fatigue.

 

The frame plays a key role within the module. On the one hand, protects the laminated housed inside thermal and mechanical stress, and secondly, serves as fixation point for connecting to the substructure.

 

The frames are designed for easy transport and installation. The distance between the end of the frame is optimized to ensure both a good seal as the maximum loss reduction.

 

It has several holes to fasten the module to the support structure and ground if necessary.

Sealed

PV modules require the use of silicone sealant high quality for bonding and sealing of frames and junction boxes of photovoltaic modules.

 

Silicone has excellent adhesion to most substrates used in the manufacture of photovoltaic modules and does not lose its flexibility in a wide temperature range so it offers perfect protection against the ingress of water into the laminate.

 

Fabricated with high efficiency. No chemical reactions with EVA material and PVF film protector ensures the chemical stability.

 

The silicone is applied in the grooves of the frame and the edge of the laminate so as to prevent any infiltration of gas or liquid that can erode the module. At the same time, elasticity serves as a protection against possible mechanical impacts during installation or handling.

Labels

This document describes data sheet and nameplate information for non-concentrating photovoltaic modules. The intent is to provide minimum information required to configure a safe and optimal system with photovoltaic modules. In this context, data sheet information is a technical description separate from the photovoltaic module. The nameplate is a sign in durable construction in the photovoltaic module.

 

This document is used for identification and traceability at each stage of the production process as part of quality control.

 Production

Each photovoltaic module consists of a set of electrically interconnected solar cells, encapsulated together with other materials that make the whole resistant to atmospheric conditions, with a robust design and easy to install. The following briefly summarizes the main stages of the manufacturing process:

 

1.- Classification of Cells

All photovoltaic cells undergo classification and grouping based on their intrinsic characteristics: color, size, performance, etc.

2.- Cells welding

Once cells sorted and grouped according to their performance characteristics and voltage are welded the electrical terminals of each of the cells.

3.- Interconnection of Strings

The welding of the cells is one of the essential steps of the manufacturing process of a solar module.

 

Solder the solar cells into strings of cells (strings) is made by connecting the front of a cell with the back of the next cell by metal strips that collect and conduct the electricity through the string or chain of photovoltaic cells.

 

The cell welding machines to weld Solar Innova cells and different types of dimensions (height, thickness, number of bus bars, mono or polycrystalline silicon).

4.- Lay-up and Interconnection

In front tempered glass is placed avoiding the deterioration of the photoelectric cells.

 

Then place the protective sheet EVA with which encapsulate the front of the cells.

 

He proceeds to place strings sequentially all leaving the same space between each of them. Once all the strings they will be welded together.

 

Then placed next EVA protective sheet with which encapsulate the back of cells.

 

Finally place the protective sheet from the back of the laminate.

 

Inside each laminate visible tag is inserted at the front thereof, with a barcode containing a serial number traceable to the manufacturing date for identification.

 

5.- Visual Inspection

The sandwich is subjected to a severe visual inspection for any fault prior to lamination.

6.- Lamination

At this stage are sealed panels using heat and pressure in a vacuum laminator (hot oven) hermetically sealed. Laminate units through the use of vacuum pumps draw air chamber lamination, creating vacuum inside the module to obtain a continuous seal.

 

During the lamination process, the prepared 5 layer module is placed in the lamination machine and heated to maximum 135º C for a period of approximately 22 minutes. The laminate that comes out is completely sealed, and when produced well, will protect the solar cells for at least 25 years.

 

The product obtained is called laminate, to be buffed to remove excess materials (EVA and TPT) that have melted in the lamination beyond the outline.

7.- ELCD Test-1

All our laminates are subjected to a test to see if there electroluminescence breaks in cells or chains.

8.- Framing and Mounting Junction Box

We proceed to place a silicone seal around all edges of the laminate in order to install an anodized aluminum frame that will provide the module for greater load resistance, then proceed to the installation of the junction box on the back of module.

9.- Cleaning

All modules are subject to a thorough clean to prevent dirt from sticking together.

10.- Dielectric Insulation Test

All our modules undergo a series of tests of high voltage insulation.

 

These tests are performed to ensure the insulation between the strings or strings and the module frame.

11.- Flash Test

The test flash equipment is an essential quality control in a production line of solar modules.

 

All our modules are introduced into a solar simulator to test them through a voltmeter is found that the current-voltage curve is the correct module.

 

The flash test is a test to measure the output performance of a solar PV module and is a standard procedure at manufacturer’s to ensure the operability of each module. During a flash test the PV module is exposed to a short (1 ms to 30 ms), bright (100 mW per sq. cm) flash of light from a xenon filled arc lamp. The output spectrum of this lamp is as close to the spectrum of the sun as possible.

 

In order to ensure accuracy of measurement , we use a plane positioning module and perfectly oriented to flash illumination is uniform over the entire surface of the module.

 

The output is collected by a computer and the data is compared to a reference solar module. The reference data is geared to the power output calibrated to standard solar irradiation.

 

The results of the flash test are compared to the specifications of the PV modules datasheets and the datas incorporated into flash reports and printed on the label on the module’s back.

12.- Labeling

Once the measurements taken each module will be labeled on the back with a clearly visible and indelible sticker where the data of the manufacturer, model and technical details of each module are reflected, all in accordance with the EN 50380:2003, information from the data sheets and nameplates for photovoltaic modules.

 

The modules are labeled on the rear part with a barcode containing a serial number traceable to the date of manufacture for identification.

 

13.- ELCD Test-2

All our modules are subjected to a test to see if there electroluminescence breaks in cells or chains.

14.- Packaging

Finally PV modules will be packaged so that no forces act that can cause breakage in its components.

 Installation

Carefully read the following product documentation and safety instructions.

 

Failure to follow these instructions will make the module warranty void.

 

1.- Purpose of this documentation

This guide contains basic information regarding Solar Innova standard photovoltaic modules, their installation and safe handling. All instructions should be read and understood before attempting installation. If there are any questions, please contact your dealer or Solar Innova for further information.

 

This documentation refers to the PV-modules themselves and is not meant to be a complete installation manual for personnel not specifically trained to PV-modules. It serves as a general reference.

 

Generally, the installer must conform to all safety precautions in this documentation, as well as the applicable national codes and standards when installing Solar Innova PV modules. Before installing a solar photovoltaic system, the installer should become familiar with the mechanical and electrical requirements for photovoltaic systems. Keep this documentation in a safe place for future reference.

2.- System components (modules and mounting system; standard scope of delivery)

  • Solar Innova standard photovoltaic modules (type designation Solar Innova SI-ESF-M-M/P125/156-XXXW, where XXX stands for nominal power values in Wp), IEC 61215 and IEC 61730 certified framed glass/foil laminates with crystalline solar cells, permanently attached junction box, and double insulated 4 mm2 wires terminated in touch safe specific PV DC-connectors.

  • The mounting system does not form part of Solar Innova supply.

  • The modules were tested with the which holds the PV-modules on their short side.

3.- General safety relevant aspects

Do not attempt to disassemble the module, and do not remove any attached nameplates or components. Doing so will make the warranty void.

 

  • The modules are qualified for application class A: Hazardous voltage (IEC 61730: higher than 50 V/DC; EN 61730: higher than 120 V/DC), hazardous power applications (higher than 240 W) where general contact access is anticipated.

  • Installing solar photovoltaic systems requires specialized skills and knowledge. It should be performed only by qualified and specially instructed personnel. The installer assumes all risk of injury, including risk of electric shock.

  • Use only equipment, connectors, wiring and mounting hardware specifically designed for use in a photovoltaic system.

 

3.1.- Precautions for mechanical installation

  • Take care when handling, transporting, storing and unpacking the modules. Do not carry modules using cables. Do not stand modules on their corners.

  • Solar Innova standard modules are designed for installation with specific photovoltaic mounting systems. Other uses lies within the full responsibility of the installer.

  • The mounting system must be capable of securely fixing Solar Innova Standard modules exposed to uplift or load pressures of more than 2400 N/m2.

  • The mounting structure and hardware must be made of durable, corrosion- and UV-resistant material.

  • Observe all instructions and safety precautions included with the mounting system to be used with the module.

  • If modules are installed on roofs (non-integral modules or panels), a fireproof underlay is needed. If modules are installed in roofs (so-called BIPV application), all applicable local, regional and national codes and regulations have to be observed.

  • The correct order to orient the module is vertical with the junction box on the higher side of it. The reason is the breather port in the junction box, that must be mounted facing downward and not be exposed to the rain.

3.2.- Precautions for electrical installation

  • Before any manipulation at an installed PV plant, switch it off first on the AC-side followed by the DC-side of the inverter or the charge controller.

  • When disconnecting wires connected to a photovoltaic module that is exposed to light, an electric arc may occur. Arcs can cause burns, start fires or otherwise create safety (up to lethal electric shock) problems.

  • Check for remaining voltage before starting the installation, and observe the local safety relevant regulations for such working conditions.

  • Make connections only in dry conditions.

  • Under normal conditions, a photovoltaic module can produce more current and/or voltage than reported at standard test conditions.

  • Accordingly, the values of Isc and Voc marked on this module should be multiplied by a factor of 1.25 when determining component voltage ratings, conductor current ratings, fuse sizes, and size of controls connected to the PV output. In the USA, refer to Section 690-8 of the National Electrical Code (NEC) for an additional multiplying factor of 125 percent (80 percent de-rating) which may be applicable.

  • Contact with a DC voltage of 30 V or more is potentially hazardous. Exercise caution when wiring or handling modules exposed to sunlight.

  • Only connect modules with the same rated output current in series. If modules are connected in series, the total voltage is equal to the sum of the individual module voltages.

  • Only connect modules or series combinations of modules with the same voltage in parallel. If modules are connected in parallel, the total current is equal to the sum of individual module or series combination currents.

  • Always use the same type of module within a particular photovoltaic system.

  • With a serial interconnection of the modules, the sum of the open circuit voltage at Standard Test Conditions (Voc @ STC) must not pass over the maximal system voltage, indicated both on the module label and on the modules datasheet.

  • If the sum of short circuit currents of the parallel connected modules passes over the reverse current (indicated in the module data sheet), string diodes or fuses have to be used in each string of modules connected in parallel. These string diodes or fuses have to be qualified for the maximum expected current and voltage.

  • Read the instructions and safety precautions for all other components used in the system, including wiring and cables, connectors, DC-breakers, inverters, etc.

  • Use appropriate safety equipment (insulated tools, insulating gloves, etc) approved for use on electrical installations.

3.3.- General prescriptions for installation.

  • Do not apply paint or adhesive to the modules.

  • Do not use mirrors or other hardware to artificially concentrate sunlight on the module.

  • When installing modules, observe all applicable local, regional and national codes and regulations. Obtain a building and/or electrical permit where required.

  • Keep children well away from the system while transporting and installing mechanical and electrical components.

  • Do not wear metallic rings, watchbands, ear, nose, or lip rings or other metallic devices while installing or troubleshooting photovoltaic systems.

  • Do not drill holes in the glass surface of the module. Doing so will destroy the module and make the warranty void.

  • Do not drill additional mounting holes in the module frame. Doing so will void the warranty.

  • Do not lift the module by grasping the module's junction box or electrical leads.

  • Do not apply paint or adhesive to the module.

  • Do not stand or step on the module. There is the danger of breaking the glass or slipping with the possibility of severe injury or death!

  • Do not drop the module or allow objects to fall on the module.

  • Do not place any heavy objects on the module.

  • Inappropriate transportation and installation may damage the module.

4.- Mechanical installation

4.1.- Robustness of modules and mounting system

Solar Innova Standard modules have been tested to withstand snow loads of up to 2’400 N/m2 and a wind pull of up to 2’400 N/m2. Tests were conducted with a static load for one hour.

 

The modules must not be mounted in regions, where higher wind- and snow loads are expected than 2’400 N/m2

 

The whole support structure needs to be strong enough to cope with above loads. Load calculations to check for the applicability for the actual installation are within the responsibility of the system planner or installer.

4.2.- Selecting the location

The amount of incident solar radiation on a surface depends on its orientation and angle of inclination. The optimum angle of inclination varies according to the latitude of the installation site: the further the distance from the equator, the steeper the optimum installation angle.

  • Select only suitable locations for installation of the modules.

  • In most cases, optimum performance is achieved if the modules face true south in northern latitudes and true north in southern latitudes.

  • For detailed information on optimal module orientation, refer to standard solar photovoltaic installation guides or a reputable solar installer or systems integrator.

  • The module should not be (partly) shaded at any time of the day.

  • Do not install the module near equipment or in locations where flammable gases can be generated or collected.

4.3.- Mounting methods

4.3.1.- Mounting with bolts

  • The module must be attached and supported by at least four bolts M6 or M8 (depending on the situation) through the indicated mounting holes.

  • Most installations will use the four inner mounting holes on the module frame.

  • Depending on the local wind and snow loads, additional mounting points may be required.

4.3.2.- Mounting with clamping hardware

  • If module clamps are used to secure the module, the torque on the clamp bolt should be around 8–10 Nm.

  • A minimum of four module clamps should be used, two on each long frame side, in general the clamping areas denoted by the wide arrows on the drawing.

  • Depending on the local wind and snow loads, additional module clamps may be required.

4.3.3.- Other

  • Other specific photovoltaic mounting methods are acceptable as long as the minimum requirements as described in chapter 4.1 are met.

5.- Electrical installation

5.1.- Grounding

  • All module frames must be properly grounded in countries, where grounding of modules is mandatory. Observe all local electric codes and regulations.

  • A bolded or screwed connection is required, it incorporates: A bolded or screwed connection is required, it incorporates: a screw size of M4 at least a star washer under the screw head or a serrated screw must penetrate non-conductive coatings like anodized frame screw and star washer in stainless steal 2 or more screws or 2 full threads of a single screw shall engage the metal

  • Devices listed and identified for grounding metallic frames of PV modules are permitted to ground the exposed metallic frames of the module to grounded mounting structures.

  • When using lay-in lugs, the grounding conductor should be inserted into the opening, and secured using the set screw.

  • Functional grounding is not foreseen for the Solar Innova Standard modules. If it is performed, local electric codes and regulations have to be observed, and used grounding means have to be isolated from live parts by reinforced insulation.

  • In any case the grounding screws, bolts or other parts have to be used separately from mounting parts of the module.

5.2.- General electrical installation

WARNING! Electrical shock hazard! Do not touch bare conductors or other potentially energized parts.

  • Photovoltaic modules convert light energy to direct-current electrical energy. They are designed for outdoor use.

  • Do not use modules of different configurations in the same system.

  • Solar Innova modules are supplied with IEC certified cables and connectors for serial electrical connections.

  • Use only additional cables which are qualified for the expected maximum current, maximum voltage and environmental conditions. Minimum cross section 4 mm2 (#12 AWG).

  • The PV-DC-connectors must never be disconnected under load! Stick to the first rule of chapter 3.2.

  • Refer to the relevant standards in your country to determine over current, conductor ampacity and size requirements.

  • For best performance, ensure that positive and negative DC wires run closely together avoiding loops, which will also reduce the strength of inductive impacts of nearby lightning strikes.

  • Following the installation of a module string, the performance of the string is checked to ensure proper functioning. At least, Isc and Voc need to be checked with appropriate equipment and circuit breakers.

6.- Maintenance

Solar Innova recommends the following maintenance items to ensure optimum performance of the module:

  • Clean the glass surface of the modules as necessary. Use water and a soft sponge or cloth for cleaning. A mild, non-abrasive cleaning agent can be used if necessary. Do not use dishwasher detergent.

  • Electrical and mechanical connections and the general condition of an installed PV-system should be checked periodically by qualified personnel to verify that they are clean, secure and undamaged.

  • Eventually occurring problems must only be investigated by qualified personnel.

  • Observe also the maintenance instructions for all other components used in the system.

7.- Shutting down the system

  • Disconnect the system from all power sources in accordance with instructions for all other components used in the system.

  • The PV-DC-connectors must never be disconnected under load! Use switches designed for being disconnected under the prevailing DC-load or stick to the first rule of chapter 3.2.

  • The system should now be out of operation and can be dismantled. In doing so, observe all safety instructions as applicable to installation.
