Solar Panels Plus manufactures it's line of SRCC Certified solar thermal collectors and is a distributor of Apricus brand solar thermal collectors. The state-of-the-art SPP-30 solar thermal systems are capable of efficiently producing enough hot water for a family of six. The Apricus 30-tube collectors provide solutions for families up to four. The Apricus 30-tube collector performance is approximately 80% of SPP performance for a 30-tube collector. SPP also offers a SPP-25, a 25-tube collector which has the approximately the performance as the Apricus AP-30 and is designed for a family of 4. The key features of the SPP Solar Thermal Collectors are as follows:

    So what makes the SPP-30 the worlds best and most efficient solar water heater collector? Our people do. The goal was to make a more durable, less costly, and easier to install collector that would outperform the competition in its solar thermal collection efficiency. We succeeded. Read on to see a few of the things we changed.

     

    We started with a better performing selective optical coating formula to absorb more, and reflect less, solar energy.

    We used a new header design with more heat exchange surface area inside the manifold (360º contact with heat transfer fluid).

    We made the condenser bulb (and receiver) longer and thinner which allows it to be inserted into single piece header instead of welding the receiver to a split header (see above diagrams). In the process we gave the bulb a larger heat exchange surface area.

    We centered the heat pipe in the tube instead of having it run down one side of the tube.

    Also, we sealed the end of the tube where it plugs into the manifold with a thermal cap, instead of leaving it exposed.

    We realize that a superior design, by itself, isn't enough. So we add a full 10-year warranty, superior quality control and fanatical customer support. Instead of simply buying a collector and putting our name on it, we make the extra effort with a factory dedicated to building our systems exactly the way we want them.

    Solar Panels Plus is pleased to offer our collectors in a installation-ready kit, or ala carte in conjunction with our full line of best-of-breed components. Due to the superior thermal performance of the SPP-30 collectors, you will use less collectors to do the same job - saving on installation labor cost, plumbing and materials costs, and roof space. And as our customer you will save even more time, money and aggravation when you take advantage of our free training, design and engineering support.
