What is a Thermal Battery

Why Perth Residents are Combining Heat Pumps with Solar Photovoltaics (PV)

Nearly a third of Perth Residents own a Solar Power roof top system. The likes of Tesla energy storage batteries are still expensive, a cheaper method to achieve Energy Independence is a thermal battery. This short article looks at why heat pumps act as a thermal battery working in conjunction with solar PV.

Heat Pumps compliment Solar Power:

1. heat pumps have a minimal and controlled known amount of power draw. The right systems can easily be timed during peak solar generating hours.

2. heat pumps take up zero roof space. This leaves more roof real estate for solar power.

3. heat pumps act like a thermal battery, storing the Energy (via hot water) for when you need it i.e. evening/morning showers

4. under the current WA Feed-in Tariff there is no encouragement to sell your renewable power i.e. you are best using it!

The graph above shows typical electricity generation for from a PV array (yellow) over the course of a year. The minimal power consumption from a heat pump (blue) can easily be covered by PV ensuring it’s free all year round. And still leaves plenty of excess energy from PV generation for other power appliances around the house. Where as a traditional solar hot water system (green) needs an energy hungry booster that can consume more power than a PV could actually generate.
