Plug-in solar panels are expected to officially go on sale in the UK in the next few months for around £500. But there are quite a few obstacles for the government and householders to overcome before this becomes the easy-to-use option that is popular in other European countries.
Plug-in solar typically consists of one or more panels, which can be mounted on the sides of a balcony (or in the garden), and then connects to the house via an inverter. The inverter converts the type of electricity that the panels generate to the voltage and frequency used by the grid.
