Flat Panel Solar Thermal Collectors for Residential and Commercial Water Heating

Ideal for warm and sunny locations, flat panel thermal collectors offer a low cost alternative to high performance evacuated tube collectors. The SPP brand USA-made flat panel solar collectors can be used to efficiently produce water temperatures in the 120-130F range when used in direct sunlight and when the outdoor ambient temperatures are above 75F.

The SPP flat panel solar collectors are among the highest rated (SRCC) flat panel thermal collectors ever tested and will contribute positively to the production of hot water. If higher temperatures are needed, or if the location has low outdoor temperatures or low sunlight conditions, then we recommend consideration of our evacuated tube collectors.

When a flat panel collector is right for the location and application, it will cost less to purchase and will perform well both at heating water and saving energy. Please browse the information on our SPP flat panel collectors and let us know of any questions you may have.
