The term off-grid refers to the situation where solar photovoltaic system is not connected to the utility grid or national grid. This approach is extremely useful in some areas in Kenya where there is little access of electricity is available or there is no national electricity grid at all.
Solar panels first convert solar energy or sunlight into DC power using what is known as the photovoltaic (PV) effect. The DC power can then be stored in a battery or converted by a solar inverter into AC power which can be used to run home appliances. Depending on the type of system excess solar energy can also be fed into the electricity grid to provide credits and further reduce electricity costs.
Most modern solar panels are made up of many silicon based photovoltaic or PV cells which generate direct current (DC) electricity from solar energy .
Solar panels generate DC electricity which needs to be converted to alternating current (AC) electricity for use in our homes and businesses which is primary the role of the solar inverter.
A solar battery is a battery that stores energy from a solar PV system. The system's panels absorb energy from the sun and convert it to electricity which then passes through the inverter for your home to use.
