What is a solar photovoltaic power plant?

A solar photovoltaic power plant is a regular power plant that converts solar energy into electricity through the photovoltaic effect. This effect occurs when sunlight photons bump into a specific material and displace an electron, which generates a direct current. The acronym PV is commonly used to refer to photovoltaics.

1. ESS introduction & features

When there is more PV power than is required to run loads, the excess PV energy is stored in the battery. That stored energy is then used to power the loads at times when there is a shortage of PV power. The percentage of battery capacity used for self-consumption is configurable. When utility grid failures are extremely rare, it could be set
