A PV array operating under normal UK conditions will produce many times more energy over its lifetime than was required for its production. Some mistakenly think that PV panels don''t produce as much energy as they take to manufacture, but this stems from the very early days of the satellite industry, when weight and efficiency was far more important than cost.

Solar array mounted on a rooftop. A solar panel is a device that converts sunlight into electricity by using photovoltaic (PV) cells. PV cells are made of materials that produce excited electrons when exposed to light. These electrons flow through a circuit and produce direct current (DC) electricity, which can be used to power various devices or be stored in batteries.
The photovoltaic array model can be simulated with any circuit simulator. The equations of the model are presented in details and the model is validated with experimental data. Manufacturers
