Many power plants today use fossil fuels as a heat source to boil water. The steam from the boiling water spins a large turbine, which drives a generator to produce electricity. However, a new generation of power plants with concentrating solar power systems uses the sun as a heat source. The three main types of concentrating solar power systems are: linear concentrator…
Efficiency of solar panels refers to the amount of irradiation energy that a solar panel can convert to electricity. From most crystalline modules it is in the range of 15-20%. The more efficient a solar panel the less square footage of solar panels are needed to produce a desired amount of solar power. For those who don’t have enough space for thin-film solar…
