Night storage heaters solar panels.
Per 250w solar panel a daily average of 1000w is produced.
For an entire night s worth of charging your storage heater will need 6000w of electricity.
Storage heaters work by storing heat generated by cheap night time electricity and releasing this heat during the day most storage heaters are wall mounted and look a bit like radiators.
If you wanted to heat a thermal storage device you would be way ahead to use solar water heaters running upward of 70 efficiency to heat water directly instead of using pv panels less than 18 efficiency to generate electricity and then wasting more efficiency trying to heat some bricks or water.
Storage heaters are primarily designed for customers who are on a time of use electricity tariff such as economy 7 and pay a cheaper rate for their energy overnight usually 12pm 7am.

Solar panels absorb the sun s heat and generate energy.
The wind doesn t always blow and the sun doesn t always shine or more accurately we can t always see it.
Let s say for the sake of easy maths that you have a storage heater that uses exactly 1000w of electricity per hour.
So the main drawback of solar air heaters is that you only get heat when the sun is shining.

Charging storage heaters with solar panels also means taking a charge during the day time instead of at night which can further complicate matters if you don t have a battery bank backup in your solar installation.
Or six 250w solar panels worth of energy.
In reality there are a couple of factors which make it improbable.
They work by drawing electricity over the course of a few hours at night and storing it as heat in a bank of clay or ceramic bricks to use the following day.
