Types of PV solar panels: description and performance
There are several types of photovoltaic (PV) solar panels for domestic use on the market. The most common 4 types of solar panels are: Monocrystalline solar panels. Polycrystalline solar panels. CIGS Thin-film solar panels. Solar Shingles. Photovoltaic solar panels are used to generate electrical energy through the photovoltaic …
Earth leakage current : Measures & protection | ENGINEERING …
There are two types of leakage currents: ac leakage and dc leakage. Dc leakage current usually applies only to end-product equipment, not to power supplies. Ac leakage current is caused by a parallel combination of capacitance and dc resistance between a Voltage source (ac line) and the grounded conductive parts of the equipment.
Earth Leakage Relay (ELR)

How to Control Leakage Current in Solar Inverter
There are two types of Leakage Current in Solar Inverter that you can choose from. There are the physical and the electronic type. For the electronic version, there are relay-based devices that run on a small amount of current each time the sensor detects a fluctuation. You can find this type in most of the devices that use photovoltaic cells.
