Installing Solar Thermal Collectors

I Just Got Finished Installing My Solar Thermal System, Its About 3pm and The Sun Has Been Shining All Day. Should I Begin Commissioning The System With Heat Transfer Fluid?

I Just Got Finished Installing My Solar Thermal System, Its About 3pm and The Sun Has Been Shining All Day.  Should I Begin Commissioning The System With Heat Transfer Fluid? NO!!!  This is dangerous.  If your collectors have been sitting in the sun all day they have been heating up.  As soon as you introduce the Heat Transfer Fluid in...

Can I Mount Solar Thermal Collectors On A Flat Roof Without Roof Penetrations?

Can I Mount Solar Thermal Collectors On A Flat Roof Without Roof Penetrations? Yes you can. Collectors can be attached to our ballast system, which uses the weight of standard patio blocks to hold the collectors in place. Wind load calculations must be done by an engineer to conform to local building codes. With the proper weight attached, collectors will...

What is the best angle to position my collectors?

This answer depends on what you are trying to accomplish. For simple Domestic Hot Water systems you should try and position you collectors at the same angle as your latitude. For systems that are tied into the home heating system, as in a combisystem, you should position you collectors 15 degrees higher than your latitude. For summertime use only...

What is more important, postioning the collectors for maximum aesthetic appeal or maximum solar gain?

Do you want to make this system perform to its highest ability or should it look nice and fit the architecture of the house? We have all seen those albatrosses on the roof that are cantilevered at a compound angle to get a few extra BTU's at the cost of aesthetic appeal. Here are some guidelines to consider when deciding what is most...

How do I attach solar panels to my shingle roof without causing leaks?

Our ConnectMaxx roof hooks are designed for any roof. We suggest that each be attached directly into a rafter using two Simpson Strong-Drive screws. Roof caulk can be used to seal these penetrations. (One installer we know used butyl rubber.) Our concave X-mount flashing then fits securely over the roof hook and under the shingles for a weatherproof connection....

How well will my collectors perform if they are not positioned perfectly?

Fortunately, solar thermal collectors are not nearly as sensitive to light conditions as PV collectors. As for performance, you have roughly a 60 degree window of opportunity to mount the collectors toward south before you begin losing a small bit of total production. In other words, your house can be situated 30 to the east of true south or...
