Solar power is the energy of the sun which can be used to generate heat or electricity. It is clean, quiet and most importantly renewable. Two broad uses are in the form of heat or electricity and light or photovoltaic cells [a small cell for your watch or light for an entire street]. The sun produces enough energy to sustain the earths need for years to come. It is economically sensible and environmentally sustainable. We are blessed with solar energy in abundance and at no cost.
Now that the world has realized the importance of sustainable development, we have started our quest to harness the renewable sources as much as possible. Several devices have been invented that run entirely on solar power.
One popular device which harnesses solar energy is the Solar Water Heater. Solar water heater turns cold water into hot water with the help of sun rays. Around 60deg to 80deg temperature can be attained depending on solar radiation. The device is useful for homes, hospitals and industries. The system can be installed on rooftops, building terraces, overhead tanks and even on the ground where sun rays fall. This method calls for lesser utility cost, less carbon dioxide release and saves plenty of energy. The initial installation cost may be high but returns are great. [Read more…]
