Solar power is the conversion of sunlight into electricity. Solar cells, also known as photovoltaic cells, are used to convert sunlight into electricity. Solar cells are made of semiconductor materials, such as silicon, that absorb sunlight and generate an electric current.

Solar power systems cannot produce electricity at night. However, solar batteries can be used in Hybrid/ Off-grid solar PV systems to store the electricity generated by the solar panels during the day and use it at night.

 The cost of a solar power system depends on a number of factors, including the size of the system, the type of solar panels used, and the cost of installation. However, the cost of solar power systems has fallen dramatically in recent years.
