a brief case study on solar water heater karnataka
CASE STUDY ON SOLAR WATER HEATER Another big advantage of solar power is that the power source is free. While oil must be drilled, and coal and uranium must be mined, the source for solar power is simply sunlight. And unlike fossil fuels, the costs of solar energy never rise. Solar power is the conversion of energy from sunlight into electricity , either directly using photovoltaic (PV), or indirectly using concentrated solar power . Concentrated solar power systems use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam. Photovoltaic cells convert light into an electric current using the photovoltaic effect . The International Energy Agency projected in 2014 that under its "high renewable" scenario, by 2050, solar pho...
