What is the difference between PV solar panels and Solar Hot Water panels?
The panels in a PV system contain semi-conducting materials that generate electricity when exposed to sunlight. This electricity can be used to power household appliances or, if the property is mains connected, surplus electricity can be sold back to the National Grid. The panels in a Solar Hot Water (SHW) system have pipes running through them and the sun’s energy heats water as it flows along these pipes. The hot water is then stored in a cylinder until it is needed.
