Solar panels means intended to absorb the sun’s rays as an energy source for power generation or heating panels.

A photovoltaic (short PV) solar cell module is generally 6 × 10 package, the connection assembly. Photovoltaic panels and constructed to produce and provide solar array solar PV systems in commercial and residential applications. Each module’s rated DC output power therefrom under standard test conditions, typically range from 100-365 watts. A module efficiency of the decision to grant the same rated output of the module area – 8% efficiency 230 watts modules with 16% efficiency 230 watts twice module area. There are a number of solar panels available is over 19% efficiency. Individual solar module can only produce a limited amount of power; most installations comprising a plurality of modules. A photovoltaic system typically includes an array of solar inverter a panel or solar module, sometimes a battery and / or solar trackers and interconnect wiring.

The price of solar power, including batteries stored, has continued to fall, many countries than from the grid (the “grid parity”) ordinary fossil fuels cheaper.
