Size your solar system

In many systems, the inverter is sized to be smaller than the panel output. For example, a 6.6 kW solar system is often paired with a 5 kW inverter. Because the panels are only rarely generating at their full rated capacity, this can be a good way to get the best value from the inverter and often makes good economic sense.

Solar panels: costs, savings and benefits explained

Battery storage lets you save your solar electricity to use when your panels aren''t generating energy. This reduces the need to import and pay for electricity from the grid during peak times. For every unit of electricity stored in a battery and used at night, it will save you around 14p. Battery storage tends to cost around £5,000 to £8,000.
