Renewable energy is generally defined as energy that comes from resources which are naturally replenished on a human timescale such as sunlight, wind, rain, tides, waves and geothermal heat. Renewable energy replaces conventional fuels in four distinct areas: electricity generation, hot water/space heating, motor fuels, and rural (off-grid) energy services. Renewable energy resources exist over wide geographical areas, in contrast to other energy sources, which are concentrated in a limited number of countries. Rapid deployment of renewable energy and energy efficiency is resulting in significant energy security, climate change mitigation, and economic benefits. In international public opinion surveys there is strong support for promoting renewable sources such as solar power and wind power.
The current and power output of photovoltaic solar panels are approximately proportional to the sun’s intensity. At a given intensity, a solar panel’s output current and operating voltage are determined by the characteristics of the load.Currently the best achieved sunlight conversion rate (solar module efficiency) is around 21.5% in new commercial products typically lower than the efficiencies of their cells in isolation. Solar panel conversion efficiency, typically in the 20 percent range, is reduced by dust, grime, pollen, bird droppings and other particulates that accumulate on the solar panel.
International reports show`s that dust and weather conditions can reduce panel`s energy consumption up to 35%. Normally users estimate that 4 cleaning operations per year are enough. The answer is no! There are uncertainties about the time and the method for the cleaning. Many solar parks are built in open areas, near agricultural farms or on the top of industrial buildings. They are widely open for undesired influence. For example when the solar panels is not maintained properly, a small film of dirt acts like a glass for the incoming sunlight and reflects it. The bird droppings consists and agricultural chemicals consist acids that could easily damage your panels.
