Check for government certification on any solar panel you are considering buying. Consider this tip a must. The government's seal of approval lets you know that these panels are deemed quality and efficient. Plus, some of the financial benefits of using solar panels (tax credits, etc.) rely on using certified panels.
When purchasing a solar energy system, make sure that you read the manufacturer's warranty carefully. This is a very expensive item, and you want to know that you will be able to get a replacement in the event something happens to it. You should purchase an extended warranty if the one that is offered is very limited.
Is it worth getting solar panels installed on your property?
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.
