Storage

A thermal store is a way of storing and managing thermal energy until it is needed. It can provide fresh mains pressure hot water and can supply your heating system (radiators, underfloor etc.). It is possible to combine the thermal store with all types, and more than one type of heating appliance, including existing or new oil, gas, or biomass boilers, wood boiler stoves, solar thermal installations and also heat pumps.

Store electrical energy in batteries for reuse later. After the sun has gone in the evening stored power can be recovered and delivered to supply the demand. If you have sufficient PV output during the day it may be worth installing a larger capacity battery. There are two basically different types, DC coupled and AC coupled.
