So Energy sells both AC and DC batteries ranging from 5kWh to 25kWh, starting from £4,817. There''s a £1,500 discount if you buy solar panels at the same time. British Gas, Good Energy and Octopus Energy also sell storage systems as part of their solar panel packages.
The first part is the power optimizer, which handles DC to DC and optimizes or conditions the solar panel''s power. There is one power optimizer per solar panel, and they keep the flow of energy equal. For example, with a standard string inverter, if one solar panel produces less energy, all the solar panels in that string will produce less energy.
The best panels for commercial use have efficiencies around 18% to 22%, but researchers are studying how to improve efficiency and energy yield while keeping production costs low.

The photovoltaic effect explained: how solar cells produce electricity. A solar cell works in three generalized steps: Light is absorbed and knocks electrons loose. Loose electrons flow, creating an electrical current. The electrical current is captured and transferred to wires. The photovoltaic effect is a complicated process, but these three
