Night storage heaters solar panels.

The achilles heel of most renewable energy generators like solar air heaters is reliability but also energy storage. 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. Or six 250w solar panels worth of energy. For an entire night s worth of charging your storage heater will need 6000w of electricity.

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. In principle using solar panels to charge storage heaters is an excellent idea to stay green and cut running costs. Let s say for the sake of easy maths that you have a storage heater that uses exactly 1000w of electricity per hour. Solarpro curve solar pool heater for above ground and in ground pools.

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. 2 2 x20 sungrabber solar pool heater above ground swimming pools add on kit.

Storage has long been a stumbling point for renewable energy but our prototype thermal battery is able to store and as required release solar energy without reliance on sunlight at all times. So the main drawback of solar air heaters is that you only get heat when the sun is shining. Solar panels absorb the sun s heat and generate energy.

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.
