About Triple Solar
Triple Solar, founded in 2009 by CEO Cees Mager, is a Dutch technology company that developed and manufactures a photovoltaic thermal (PVT) heat pump system designed to provide a gas-free energy solution for homes. The firm aims to reduce CO2 emissions from residential heating and make sustainable energy more accessible and affordable. The company's core product is an integrated system that provides heating, cooling, hot water, and electricity. It combines PVT heat pump panels with a proprietary indoor heat pump. The front of the panels consists of photovoltaic (PV) cells that convert sunlight into electricity, while the back acts as a thermal exchanger (T) that extracts ambient energy from the outside air, sunlight, and daylight. This energy is then transferred to the heat pump, which converts it into usable heat for heating and hot water, functioning 24 hours a day, even in freezing conditions down to -10°C. A key feature of the system is the absence of a noisy outdoor unit, with the panels on the roof serving as the source. The indoor heat pump is compact, lightweight, and uses propane, a natural refrigerant with a low global warming potential. Triple Solar targets both new construction and existing buildings, collaborating with installers, housing associations, and knowledge institutions to promote adoption. Its business model involves selling its system as a package to distributors, who then supply installers. The company has received significant financial backing to support its growth. In 2018, it received support from the PDENH fund to accelerate development and production. In early 2024, it secured €10 million in a growth funding round from pension fund ABP and existing shareholders, including PDENH, DOEN Participaties, and Enfuro Ventures. This capital is intended for international expansion, increasing production capacity, and further product development. The company has expanded its operations into Germany and serves B2B clients across the UK.
