Apples To Oranges

With the growing industry of Solar Thermal Products, a lot of products are hitting the market that are not built correctly, efficient, tested, or certified by the SRCC. As much as 60% Federal and State Tax Credits are given in some areas for qualified Solar Thermal Systems. That along would save you several thousand dollars in costs. But the panels must be SRCC rated for the any tax credits.

In your shopping, you will find simple Flat Plat Solar Collectors, or Evacuated Tube Solar Collectors for sale within your local area.  Some Evac Tube panels are sold as Evacuated Tube Collectors but are actually the less efficient Evacuated U-Tube collectors and not Evacuated “Heat-Pipe” Solar Collectors.

When comparing Flat Panels to Evacuated Tube “heat pipe” panels, your earthly solar location is important. Flat panels are less efficient in cold weather in areas with temps near and below freezing. Be aware of your needs.

It is important that you ask for SRCC certification. Your Federal and State Tax Credits credits to you depend on the certification.




Our Evacuated Tube Solar Thermal Panels and Flat Plate Panels have met all the SRCC requirements and rated to be installed  as a quality product able to produce extreme amounts of Solar Energy for our customers, reduce their carbon footprints, and reduce their fossil fuel expenses.

Back to the basics… compare apples to oranges when picking solar thermal panels. Get expert advice and design.

In the sunny middle of the country, one Sq Ft of our Solar Evacuated Tube Panels will produce an average 290,000 Btu’s per year at an initial panel cost of $38 per Sq Ft. On a bright winter day they will produce an average of 1,400 Btu’s per Sq Ft per day.

In the sunny middle of the country, one Sq Ft of our Solar Flat Panels will produce an average of 294,000 Btu’s per year at an initial panel cost of $32 per Sq Ft.  On a bright Fall or Spring day they will produce  1,418  Btu’s per Sq Ft per day. If you are in an area where near or below freezing temps are normal for the heating months, then  Solar Flat Panels will not produce enough energy to match the Evacuated tubes. Solar Evacuated Tubes would be the proper and efficient Solar Panels for that climate.

Flat Panels are more efficient in warmer climates than Evacuated Tube Panels, as Flat Panels are affected by outside air temp and cold wind. Evacuated Tube Panels are more efficient in warm to sub-freezing climates, as they are not affected by outside air temperature or cold wind,  and absorb available sunlight from 360 degrees.
