What is 6kW Solar System?

A 6kW system is a solar power system capable of generating up to 6000 watts of electricity. On average, a 6kW solar system will generate between 4800 to 6000 kWh annually, which is sufficient to power a larger house in the UK with 5-6 occupants. A typical 6kW system consists of solar panels, a 6kW inverter that converts solar energy (DC) into usable electricity (AC), and optionally, batteries for storing excess energy for later use. However, it’s important to note that the addition of batteries will increase the overall cost of the system.
