If you have a pool, don't even think of heating it any other way than solar! This is easily the most efficient use of solar power there is and it will save you a bundle. Solar heating systems cost about the same or less than conventional systems and basically operate themselves so stop wasting your money doing it the old-fashioned way!
Avoid stepping on solar panels, unless you really need to. These can cost you quite a bit of money, so they need to be kept in great condition. The most fragile part is typically the end of each panel, so avoid that area.

Making decisions under pressure can be more costly later on.
