Sunamp Ltd. has signed an agreement with Trina Solar to develop an integrated solution combining Sunamp heat batteries now made in Scotland with heat pumps manufactured at Trina’s new factory in Changzhou, China.

With more than 14,000 employees, Trina is one of the world’s largest PV panel manufacturers. Sunamp, based in Edinburgh, Scotland, has about 30 employees. Sunamp’s Uniq heat batteries, made at Sunamp’s factory in East Lothian, use a salt-based phase change material to store excess energy generated by solar PV systems. The stored energy is released on demand to provide heat and hot water.

The two companies signed a memo of understanding Oct. 20 at the opening of Trina’s new heat pump factory.

The combined system will use Sunamp’s batteries in conjunction with solar panels and heat pumps to reduce energy costs and carbon emissions. According to Sunamp, the system will offer 23 to 35kWh of storage.
