Always use non abrasive cleansers on your solar panels. An abrasive cleaner can scratch the surface of the panel and cause permanent damage and affect how well the solar panel works. There are commercial cleaning solutions to use or you can use a pool skimmer with a very soft cloth on it.
Fossil fuels that are used around the world do not help our environment. In fact, the cause a great deal of damage to the world we live on. Solar energy will provide us with the power we need without causing any damage to our earth. There will be no more gases, carcinogens or even carbon dioxide produced by solar energy.
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.
