Use winter sunshine hours instead of summer hours whenever you are calculating how many solar panels you will need. This is because winter sunshine hours only add up to about half that of summer. It is better to overestimate how many panels you will need rather than underestimate. If you underestimate, you will end up losing power when you need it.
Don't look at solar panels as a do it yourself project. You are putting serious funds into these panels, and any mistake can be very costly. Find the right help. Do your research online to come up with the best installers out there near you and interview a few before making any decisions.
When thinking about investing in a solar panel system, you should consider such factors as the typical weather conditions in your area. Solar panels are a good option if there are five hours of sunlight a day in your area. When there is little sun or snow on the roof, you may have to use other sources of energy.

Do the math prior to investing in solar power. Not every location is a good bet to deliver energy savings. The best option is to look into the costs and the potential earnings (based off your sun conditions) to see what the costs will really be like. Sometimes, it'll be way more costly to use solar.
There is no need to tear apart your roof to use solar energy. You can make small switches like putting in solar powered outside lights. They charge their batteries during the day, switching on and providing illumination all night.
