Do not clean your solar panels with abrasive chemicals. You should use some lukewarm water, a soft cloth and some biodegradable soap if needed. Clean your panels at least once a month or more frequently if you notice your green energy system is not producing as much power as it should.
Get your financial figures right before deciding on a solar system. You need to weigh the cost of the system against how much energy it will save you. Take the cost of the system and multiply it by its' lifespan. Now figure out how much energy you will use in that lifespan to determine if it is right for you.

Minimize the upfront costs of solar panels by considering a lease instead of a purchase. This spreads the payments over a long-term period into monthly installments, so you could actually start saving money immediately. Still, consider how long you will be in that building, as the long-term periods usually run a decade.
Once your panels are in place, keep an eye on them and monitor them regularly. Get to know what you daily output of energy is, what everything looks like when operating optimally and even keep a record of such things. This can help you quickly notice when something isn't working correctly and help you ascertain where the problem is.
