A solar inverter, or converter or PV inverter, converts the variable direct current (DC) output of a photovoltaic (PV) solar panel into a utility frequency alternating current (AC) that can be fed into a commercial electrical grid or used by a local, off-grid electrical network.
A solar battery is simply a battery charged with energy from solar panels. There are lots of types – tiny to utility scale.
Solar powered flashlights or solar powered torches are flashlights powered by solar energy stored in rechargeable batteries. Most of these flashlights use light-emitting diodes lamps since they have lower energy consumption compared to incandescent light bulbs.
A solar energy-powered water pump is a water pump running on the electricity that is generated by solar photovoltaic modules. A water pump basically is an electro-mechanical device that moves water by mechanical action and powered by an electricity generating source, which can be manifold, such as diesel engines, wind power or solar energy.
Domestic solar manufacturing capacity is almost 6 GW in a 10 GW market, however, Indian manufacturers managed to corner only about 10-15 per cent of the Indian market share raising doubts about their future.
A solar-powered refrigerator is a refrigerator which runs on energy directly provided by sun, and may include photovoltaic or solar thermal energy.
Solar-powered refrigerators are typically used in off-the-grid locations where utility provided AC power is not available.
Solar cell phone chargers use solar panels to charge cell phone batteries. They are an alternative to conventional electrical cell phone chargers and in some cases can be plugged into an electrical outlet.
Solar cell phone chargers come in different shapes and configurations including folding and rotating types. Phone charge times vary depending on the battery capacity installed which continues to increase, further extending the charge times of solar chargers.
A solar fan is a mechanical fan powered by solar panels. The solar panels are either mounted on the device or are installed independently. Solar fans mostly do not require secondary power sources other than solar power, as most of them are used for cooling purposes during day time. Some types are also used for heating purposes. It runs the fastest when it is the hottest outside providing savings on air conditioning costs.
