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.
Be sure mountings on solar energy panels are engineer certified for your area. For instance, if if you're in an area that gets frequent cyclones, the mountings need to be cyclone rated. High-quality systems will be wind certified to ensure they don't blow away in a huge wind storm. Mounting is an important part of the system and not all suppliers regard them that way. Stay alert when buying your system to make sure they have proper certifications.
When it comes to solar water heaters, be realistic. They're typically only 30% more efficient than any other form of water heater. Second, don't think that just because you shower in the dark means you'll have to deal with cold water. Water heated by solar power should stay warm for 24 hours.

Do not rush in selecting the first solar power system you come across. Before you make a commitment with a company, you need to make sure you cannot find any better deals elsewhere. Check out your town's federal, state, and local incentives first. You can find this information at the DSIRE database.
