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.
See how to test your solar panel for open voltage and current reading. Results will vary depending on sun strength, time of day, angle of light and temperature.
If you are leasing or making payments on a solar energy system, you need to be aware of the uncertain possibility of selling your home later. Often, there can be provisions made in your contract for transferring the solar energy system to your new home. Make sure you look into your contract.
Make sure that any solar panels you put up are actually cost effective. While the installation cost can be dented with government assistance, you need to know how long it will take for energy savings to return your investment. Also factor in that you are not likely to get the same amount of power every single month.
