Solar panels absorb the sunlight as a source of energy to generate electricity or heat.
A photovoltaic (PV) module is a packaged, connect assembly of typically 6×10 photovoltaic solar cells. Photovoltaic modules constitute the photovoltaic array of a photovoltaic system that generates and supplies solar electricity in commercial and residential applications. Each module is rated by its DC output power under standard test conditions (STC), and typically ranges from 100 to 365 Watts (W). A photovoltaic system typically includes an array of photovoltaic modules, an inverter, a battery pack for storage, interconnection wiring, and optionally a solar tracking mechanism.
Solar panels are an environmentally friendly way of producing electricity for your home. As mentioned above, the technology relies on photovoltaic (PV) cells to turn sunlight into electricity. So, in essence, solar panels work by producing extra energy which either gets used by you, or gets sent to the grid. Any electricity you consume which is in excess of what your panels are producing will be sourced from the grid.
