Solar Panel

Solar panels are one of the most important parts of solar street lights , such as solar panels convert solar energy into electricity .There are 2 types of solar panel : mono crystalline and poly crystalline . Conversion rate of mono - crystalline solar panel is much higher than the poly - crystal .

Lighting Fixture

LED is the general uses fear as fuente de luz of modern solar street light , since the LED lumens provide con mucho más altas energíael lower consumption . Energy consumption of the LED accessory of at least 50 % more than under HPS accessory that widely used as fuente enFarolas traditional lighting . LEDs lack of warming tiempo también permite the use of detectors movimiento paralasganancias of efficiency .

Rechargeable Battery

Batteries store electricity from solar panels during the day and provide power to the device overnight. The life cycle Battery is very important for the life of the light and the battery capacity will affect reserve days of lights .Generally there are two types of batteries : deep cycle gel cell battery and lead acid battery and more.

Controller

Controller is also very important for solar street light . A controller often decide to switch / charging and lighting .Some modern automatic controller so that users can decide the appropriate time charging , lighting and dimming .

Pole
Pals strengths are required for all street lights , especially for solar street lights , as there are components mounted on top of thePole : oil lamps , panels and batteries at some point. And wind resistance must also be taken into account when choosing the pole .Types

Solar street light at the bus stop

Each street light can have your own solar panel , independent of other street lights . Alternatively, a number of panels can be installed as a central power supply in a separate power supply and a series of street lights .

Advantages

Solar street lights are independent of the utility grid. Hence, the operation costs are minimized.Solar street lights require much less maintenance compared to conventional street lights.Since external wires are eliminated, risk of accidents is minimized.

This is a non polluting source of electricity Separate parts of solar system can be easily carried to the remote areas

Solar panel

component of a larger photovoltaic system to generate and supply electricity to residential and commercial applications. Each module has its power to DC output in standard test conditions (STC), and generally ranging from 100 to 320 watts. The efficiency of a module

determines the area of a given module the same nominal power - 230 watts efficient module 8% have twice the area of a 230 watt module efficiency 16%. There are a few solar panels available that are exceeding the 19% efficiency. A single solar module can produce only a

limited amount of energy; Most installations contain multiple modules. A PV system typically includes a panel or a set of solar modules, inverter, and sometimes a battery and / or solar tracker and interconnection wiring.

Solar panel

The solar panel refers either to a PV module, solar panel hot water, or a set of solar photovoltaic (PV) modules electrically connected and mounted on a support structure. A PV module is a packaged set of connected solar cells. Solar panels can be used as a component of a larger photovoltaic system to generate and supply electricity to residential and commercial applications. Each module has its power to DC output in standard test conditions (STC), and generally ranging from 100 to 320 watts. The efficiency of a module determines the area of a given module the same nominal power - 230 watts efficient module 8% have twice the area of a 230 watt module efficiency 16%. There are a few solar panels available that are exceeding the 19% efficiency. A single solar module can produce only a limited amount of energy; Most installations contain multiple modules. A PV system typically includes a panel or a set of solar modules, inverter, and sometimes a battery and / or solar tracker and interconnection wiring.

Solar panel maintenance

Conversion efficiency solar panel , typically in the range of 20 per cent, reduced to dust, dirt, pollen and other particles accumulate on the solar panel . "A dirty solar panel can reduce its energy capacity to 30 percent in high dust / pollen or desert areas , "says Seamus Curran ,associate professor of physics at the University of Houston and director of the Institute of

Nanoenergy , specializing in the design , engineering and assembly of nanostructures .

For solar panels not self - cleaning , regular cleaning of a company or professional window washing can be done in private a regular schedule . According A1 The Clear Choice, a California-based company that makes commercial cleaning solar panels services , " Solar panels are similar to the windows of your car , home or business. They get dirty rain , dust , pollen , soot , smoke,emissions from cars, the ashes of the fireplace , bird droppings , leaves and other debris environment. Which prevents dirt and debris to be sunlightabsorbed into the panels , reducing their effectiveness. The result is less energy to use in your business or for sale to the public service company .

Smart solar modules

Several companies have begun incorporating electronics into PV modules . This allows you to track the maximum power point ( MPPT ) to each module individually , and measuring performance data for monitoring and fault detection module level . Some of these solutions make use of power optimizers , a DC - DC converter technology developed to maximize the harvest solar power photovoltaic systems . From 2010 or so, these electronic products can also offset the effects of shadow , a shadow falling across a section of a module causes the electrical output of one or more chains of cells in the module to fall to zero , but have

Out of all the module down to zero.
