Description

Street lighting using solar streetlights has developed as one of the major applications of solar photovoltaics.

 

We have equipment specifically designed for this application, able to illuminate isolated parts of the grid with a very low maintenance costs.

 

All our outdoor luminaires are based on high-performance LEDs, and incorporating our unique digital control system allowing the control of the functions of the luminaire (optical, temperature, etc.) and ensure their useful life, and an optical system modular developed to offer virtually exclusive photometric solutions for each client.

 

It is increasingly common to see on highways, streets and gardens lamps powered by solar energy. These devices, which allow to use solar energy to illuminate the streets, as part of our urban landscape. Our solar lamps are designed as a solution for outdoor lighting systems for public and private sector.

 

Our solar lamps are designed as a solution for outdoor lighting systems for public and private sector, there are a number of advantages over conventional lighting:

Economic

Installation significant cost and time savings. The conventional lighting has a number of costs such as civil works, manholes, pipes, copper cables, control panels, transformers, licenses, accountants, contracts with utilities, etc. With urban solar lamp, only you need to enable a concrete base as any conventional streetlight.

Maintenance

Maintenance costs for conventional luminaires represent a high percentage in terms of installation, as they have to withdraw lamps and ballasts with a very limited life. The incorporation of the latest LED technology allows a service life exceeding 11 years module, thus saving energy translated into quantitative terms is very high. The design and engineering of our lamp provides over 25 years life so obviously, the system will pay independently. In the environmental field we highlight the following:

  • With the installation of our streetlights, we contribute to the use and operation of a source of clean, renewable energy and an important factor in how our environment, reduce CO2 emissions.

  • We reduce light pollution, because not emit light in the sky.

Performance

During daylight hours the system captures and stores solar energy in the form of electricity. At dusk, the system automatically turns on the LED luminaire progressively, depending on the external light, using the energy stored in the batteries, providing the necessary light to illuminate space. At dawn, the LED module is automatically disabled starting a new cycle.

 Components

Solar Innova uses only the latest materials to manufacture its solar photovoltaic streetlights:

 

Solar Photovoltaic Modules

Are the elements responsible for capturing the sun's energy and transform it into electricity.

 

They tend to be clearly identifiable by their prominent position. Typically placed on top of the structure to achieve greater uptake of solar energy. The panels should always facing the Earth Ecuador and proper tilt function of latitude (to exist in this regard several criteria, one of them consisting of tilting the same number of degrees of latitude + 5).

 

Solar panels are quite similar to those used for other photovoltaic applications, only suitable in size.

Batteries

Component designed to store the energy collected by the panels during the day to use it at night in the lighting of the lamps.

 

Here the same principles as in the rest of the solar PV installations, requiring rechargeable batteries tolerate a great depth of discharge.

 

In the streetlights, the location of this component depends on the manufacturer. Some place it in a high area under the panel or under the luminaire. Thus the potential risks of tampering is reduced. This placement but also hinders change operations and maintenance.

 

Other manufacturers choose instead to place it on the bottom where it is easier to manipulate for repairs or replacements, however is more exposed to undue people have access to it.

 

The choice of one type or another depends on the purpose and function of the area where they are to be placed. In any case to operate these components with low voltage of 12 volts, the risk of serious accidents is very small.

Electronic

Optimize and rationalize the use of stored energy. They are used to automate the switching on and off of the lights avoiding unnecessary waste of light besides getting the component life is lengthened. This regulation is achieved in two ways:

  • Through programmable devices on and off the lights based on the information entered on the times of sunrise and sunset every day of the year where you will be placing.

  • By a small photodetector that detects the level of ambient natural light. When the cell detects low light intensity outside (night), turn on the lights when the light intensity is high (day), off.

When after several cloudy days has not been able to recharge the battery properly and this is at a load level too low there is a system that prevents the lights come on to prevent battery discharge continue. Excessive discharge the battery may cause the blade is unable to recharge and thus unusable. This system also ensures that the time be enough sun again for recharging cycle is normally restored.

Luminaires

Elements that convert energy stored in the battery light. In all these components efficient lamps are used to maximize the energy captured: fluorescent lamps, sodium lamps or LEDs, incandescent bulbs completely discarded for being great wasteful of energy.

Box

Galvanized metal box containing electronics and battery management.

Pole

It is responsible for supporting other elements of the lamp, has a tubular shape and is made of hot galvanized steel and powder coated to ensure corrosion resistance.
