One of our clients contacted us with the following letter:

Hi Jens,

Just thought I’d update you to let you know we are very pleased at the success of the Solar panels and controllers you installed.  Last week we had the pool up to 90 degrees just from the solar panels!!!!   The switching between solar/gas/off is working beautifully.   After the cooler days and intense rain our pool dropped to 78 degrees (we have the gas heater set to come on if the temp drops below 78).   Today (one day of sun) the pool was back up to 83/84 with just the solar.

Thanks again for your professional and honest service.  It was a pleasure having you and your daughter install the solar heating for our pool.   We would be more than happy to recommend you and your company.
