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.
Find a reputable company. With the rapidly rising popularity of solar energy, new companies are springing up left and right to take advantage. A solar energy installation is a big purchase that should last you many years. When shopping for your system, look for a company that you can be confident will still be around ten or even twenty years from now.
Once you buy a system, one of the first things you will notice is how quiet your solar cells are. As they draw in energy from the sun, they make absolutely no noise. This is something that most owners appreciate, as all other renewable energy sources make some noise as they operate. Particularly if you have a stressful job or a stressful life, the last thing you need is a noisy system interrupting your few moments of peace.
This is my initial solar test setup. I am trying to fit all energy needs into a 1.5KW envelope. Cost of around R40-45K.
If you are interested in joining the green movement and helping the Earth, harnessing power from the sun is the way to go. It's natural, it's clean and it's renewable, which means that you can't use it all up. Therefore, not only can solar power help you save money on your electricity bill, it is also good for the environment.
Know how light mixes with the trees around your property. You may think you've got the perfect spot for a solar panel, but watch it throughout the day. The sun coming in from different angles may lead to surprising shadows from trees and foliage. This will affect your solar output.
