Product Description

Solar panels, generally comprising of arrays of photovoltaic cells, use the solar energy directly from the sun to generate electricity for our daily use. Being environment friendly in nature, solar panels collect the solar energy which is available in abundance on our planet and convert it using the advanced technology developed by human beings. This invention of humans has led to a great achievement in world's history of conserving non-renewable resources and saving the planet as well as the natural resources from depletion.
