Check that your solar-energy installer has the proper licenses and insurance. Installing solar panels on a steep roof is a delicate job, and you should feel confident that your installers know what they are doing. At a minimum, look for a contracting license, workers compensation insurance, and general liability insurance.
Be aware that you can still get solar power benefits even if you live in a chilly, overcast area. It doesn't need to be like Florida all year round for it to be a big part of your energy savings goals. Great solar power output can come on poor weather days.
Low prices can be very attractive but keep in mind that solar panels and their installation is not cheap. If a vendor has extremely low prices, you are probably getting low quality equipment or even second hand equipment. It is best to invest in quality solar panels and hire a trustworthy contractor to install them.
