Don't walk on solar panels unless you really need to. They cost a lot of money, and you don't want to inadvertently damage them. Do not walk on the ends, as they are the most unstable parts.

For better savings on your utility bill, keep your solar panels clean. Solar panels are practically silent and since you don't touch them, you can easily forget them. The cleaner their glass panels are, the more clear surface area the sun has to "work with." There's no set amount of time that you should clean them. If you live in an area with lots of wind, dust or construction, they may need cleaned frequently. Some ares may require weekly cleanings.
