Solar Power generation systems are made of two components: Photovoltaic cells and Power inverters. The photovoltaic cells utilise the power of sunlight to convert photons to clean DC (Direct Current) electricity.
As the installations and demand for PV systems increases, so does the need for effective electrical protection. PV systems, as with all electrical power systems, must have appropriate overcurrent protection for equipment and conductors.
PV systems, as with all electrical power systems, must have appropriate overcurrent protection for equipment and conductors. Globally there is a push for utilizing higher voltages (trending to 1000Vdc and above) to achieve more efficiency. This will mean an even greater need for circuit protection in the future.
The Electricity generated by the Solar Cells is then fed into a Power Inverter (PV inverter) that converts and regulates the DC source into usable AC (Alternate Current) power. This AC power can then be used locally for specific remote equipment, residential homes or fed directly back into the power grid and used as clean, environmental energy.
Over the last 50 years, Solar Photovoltaic (PV) systems have evolved into a mature, sustainable and adaptive technology. This technology is improving as solar cells increase in efficiency and modules attain better aesthetic appearance.
An individual panel is made up of a number of photovoltaic cells connected in series. The voltage output of a Solar Panel is defined by the number of individual cells in series. When multiple panels are connected in series, it forms a ‘string’. When ‘strings’ are connected in parallel, it forms an ‘array’.

DC Surge Protection For Solar Power Systems
Surge protection devices (SPDs) are used to protect the photovoltaic power system by absorbing or diverting transient voltage surges before they can reach and damage the electronic components. SPDs are designed to limit the voltage that reaches the equipment and provide a safe path for excess current to flow to the ground.
