3 kVA solar power plant for households or offices

Yield expectation and PV run time

In average, this solar power plant is expected to produce around 14 kWh in eastern Africa per day. Enough to cover the energy consumption of households or many small/medium offices.

An example calculation of energy consumption is shown in the table below. This 3 kVA solar power plant can run for example the following appliances during the day and the remaining power is loading the storage battery for the nighttime. However, in the nighttime some of the appliances have to be switch off.

All household appliances, which are available in the market (like refrigerator, lightning, fan, TV, PC and more), can be operated with this solar hybrid PV power design

Design of the PV power plant

This solar power system is designed for independent power supply and hybrid application. It can be operate as a stand-alone power supply system. As required, it is possible to connect a generator for hybrid application.

If the power supply from the photovoltaic (PV) panels is insufficient, the PV system automatically supplements the missing power from the battery storage system. At night or at complete breakdown of the PV panels and empty battery storage, the PV system automatically switches off to protect the lifetime of the battery storage. The system switches automatically to PV supply as soon as the sunrise
