Solar panel

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.
