#Off grid solar systems install#
Most off-grid solar system users install an alternative source of electricity, such as a generator, to serve as back-up if the system goes down or in the winter months when energy production is low. It regulates the current and voltage received from the panels so the batteries are not damaged as a result of overcharging.
This is a safety device designed to protect the batteries. The batteries continue to store excess electricity as the panels generate power during the day, making the electricity available for use later when the panels have stopped generating power. Solar batteriesīatteries act as storage devices that enable the system to continue running after the sun has gone down. But others use a micro-inverter system where each panel has its own micro-inverter attached to the back of the panel. In many solar-powered systems, the solar panels are linked together in series. This piece of equipment is responsible for converting the direct current (DC) produced by the solar panels into a ready-to-use alternating current (AC). The amount of electricity generated by the panels altogether depends on solar irradiation, the efficiency of the panels, the angle of tilt and a host of other factors such as losses from shading. The PV cells on a panel are linked together and connected to adjacent panels via cables, although some panels may channel their electricity directly into the system if they have inverters attached to them. Solar panels are made up of silicon-based photovoltaic (PV) cells encased in glass and an aluminium frame. This is arguably the most important component in the system because this is primarily where the electricity is generated from.
The essential components of an off-grid solar system are: It can also liberate those in larger towns or cities from utility-grid inefficiencies such as grid collapse or power failure. The system is very beneficial to people living in remote areas with no access to the utility grid. An off-grid solar system is a stand-alone method of generating electricity from solar panels.
