CONFUSED ?

WE HAVE ALWAYS FOUND THAT THE SOLAR HOT WATER INDUSTRY IS THE MOST CONFUSING WHEN TRYING TO EVALUATE PERFORMANCE AND THAT PROBABLY SUITS SOME PEOPLE.

Do you find it practically impossible to determine which system performs best.

Have you heard quotes like: “one of the best” or “one of the most efficient” or “look at the brand name, it must be the best”……

GOOD NEWS !!!

YOU WON’T HAVE THAT PROBLEM ANY MORE…..

Here’s why ! We’ll tell you about a government performance comparison for solar hot water that no manufacturer wants you to know about.

In Europe, there is NO solar hot water comparison system or standard, i.e. a simple, this product does X and that product does Y, UNDER THE SAME TEST CONDITIONS.

BUT, not everywhere is like Europe, the USA has such a rating system in place and many manufacturers and distributors don’t want you to know about it.

The USA decided that they would NOT accept any information on performance from solar hot water manufacturers, because THE RESULTS could be biased. They decided on a much tougher unbiased independent scheme.

They said: SEND US YOUR Equipment, We will put it into a government certified laboratory, test it under benchmark conditions, and publish the results in a public database for consumers and industry alike to make direct, balanced and fair performance and cost comparisons.

Here for your convenience, we have a download of the current database so you can now compare a Surface Power solar hot water system to every other solar hot water system in the world (over 900 other systems) as of 3/2/2012, the USA public performance database as maintained by SRCC.

ONE NOTE OF CAUTION: Many European solar collectors don’t want to be compared so they are sold in Europe with different brand or model numbers, if you cannot find a solar hot water collector on the list, simply compare the “Gross Size” figure, the “description” and google for a picture and you’ll find which one on the list is the one you are trying to identify. (Don’t worry if you find a lot of different collectors that fit, they are all probably made by the same manufacturer.)

Surface Power’s solar hot water system was tested and certified in Palo Alto, California. The output performance per sqm aperture has been shortened to 2 decimal places for convenience.

Surface Power does not use software programs, excel spreadsheets or guesstimates when publishing performance. We use real data or government certifications. PROOF NOT PROMISES.

All the data in this list is public and maintained by SRCC, we assume that it is all accurate as downloaded. (we can confirm our results are as we hold the certificates). We are not liable for mistakes on the data as we are not the data controller making it public.
