A photovoltaic solar cells that convert sunlight into electricity. A photovoltaic system contains many different elements, such as cells, electrical, mechanical joints, fasteners and a way to convert the electrical output. Due to the low voltage of individual solar cells are typically 0.5 V solar cells in photovoltaic modules, which are then linked together to form arrays.
The electricity produced can be stored in an autonomous system in a plant or island, preserved inPowered by batteries or a mains larger. For the power level, power generators for home use for residential systems, or hybrids are used. Depending on the application of energy production, the balance of the output may be different. The balance of production (BOS) depends on the load profile and the type of system.
Stand-alone systems - This should not depend on centralized generators or grid connection. Stand-alone systems can be so smallas a calculator or as large as a spaceship. If the load does not depend on sunlight, the current must be buffered by a battery. Where weight is not important, lead-acid batteries are used.
Charge controllers are used to damage the battery by connecting and disconnecting the battery to prevent excessive. To maximize the performance of solar cells, modules optimized with a maximum power point tracking (MPPT) system. In very small devices, only the DC is used. In large systems such asBuildings and houses, you need AC. The inverters are used to convert DC to AC.
The important thing to keep in mind is the ultimate use of solar photovoltaics. This will help you decide if you need a charge controller, inverter, or other type of attachment.
