Q:

How long should I expect my pool solar collectors to last?

A:

Most solar pool heating collectors have warranties in excess of 10 years - some have 15 years, even lifetime warranties are available. It is not unusual for solar pool heating collectors to last well in excess of 15 years with minimal maintenance. (Most often out-lasting the shingles upon which they were installed!)

Note:The solar collectors must be properly installed if they are to be expected to last. Some plastic collectors can be turned over to expose the opposite side and thereby almost doubling the useful life of the collector.

 

Q:

Will solar collectors damage my roof?

A:

When properly installed and maintained solar collectors will not damage a roof. In fact they will protect the roof that is under them from weathering.

Note: Leaking collectors will damage a roof over time. The chemicals in pool water can damage asphalt shingles if they are kept wet by a leak. (Most leaks occur at the couplers on solar collectors and are easy to fix. Some solar collectors are much more prone to leaking!)

 

Q:

Is there a downside to heating my pool with solar?

A:

Yes. Your pool will be significantly warmer than before when you (didn't) heat it with a conventional heater. This means you will use the pool more - more swimming, more pool parties, more friends and kids using the pool, which means you will need to add more chemical to the pool to keep it clean. Also note - your entertainment costs will likely go up too (beer, pretzles, sunblock, the cost of washing towels, etc.!-)

 

Q:

Will pool chemicals or salt water harm the solar panels or solar equipment?

A:

No, not if you are using a plastic or rubber solar collector with PVC plumbing.

Solar collectors with fluid channels made of copper or stainless steel will have major problems. They must not have pool water circulated directly through them, or they will be damaged very quickly and potential stain your pool!! If this type of solar collector is used - presumably for heating an indoor pool that is used all year - a heat exchanger designed specifically for salt water must be used to separate the pool water from the solar heat collecting loop fluid.
