SolarTide
SolarTide HPSC series of evacuated tube solar collectors are suitable for both residential and commercial applications.
The design of the HPSC solar collector is a culmination of nearly 15 years of feedback from installers and solar professionals all over the world and aims to meet their requirements with the following key features:
● Easy and Safety Packing design
● Lightweight manifold and bracket design
● Anodized Aluminum Alloy mounting frames
● Extremely reliable header design, less brazing points
● All glass wool insulation for high temperature stability
● Extreme cold resilience (freeze protected heat pipes)
● UV stabilized components
● High wind load strength and High snow load strength
● Easy plug-in installation
HPSC collectors are available in 10 to 30 tube sizes and have a number of options depending on the local market requirements.

How It Works
Construction
The HPSC solar collector is comprised of four main parts:
Evacuated Tube
Absorbs solar energy and converts it to usable heat. Vacuum between the two glass layers insulates against heat loss.
Heat Pipe
Copper vacuum pipe that transfers the heat from within the ET up to the manifold.
Manifold
Insulated box containing the copper header pipe. The header is a pair of contoured copper pipes with dry connect sockets that the heat pipes plug into.
Mounting Frame
Strong and easy to install with various options to match different mounting methods.
