Be realistic about the costs of having a solar energy system. If you're paying much less than other systems that are around the same size as yours, you may have poor equipment or installation work. Like Backyard revolution reviews with many things in life you get what you pay for. Quality installation work and equipment isn't going to be cheap. You may have substantial savings by going with a large company, but other companies may be cutting corners to keep costs down.
Once your solar panels are installed, you need to keep track of how much power you are producing and using on a daily basis. Invest in a quality monitoring system and look at the data as often as possible. If you notice your panels are not producing as much energy as usual, it might be time to clean them.
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.
You should only invest in a total solar energy system if you have already paid off your house. Solar panels are a pretty hefty financial obligation, especially considering how often people move. You don't want to lose your home or still be paying on solar panels if you decide to move.
When you are building your own solar panel systems, expect to build multiple arrays for the highest-efficiency. A solar panel can only generate a certain amount of energy--usually a fairly low number--which means that you need more than one panel. Multiple panels in the right spots is a recipe for success.
