You should assess how much energy you need for your household before investing in a solar energy system. You will get the most out of your solar energy system if it is powerful enough to cover all your energy needs and allows you to sell a small quantity of power to the main grid.
How dense your solar panels are will determine their efficiency. Getting high density solar panels may cost you quite a bit, but after a while they'll pay for themselves because they produce more power. Before you select your solar panels, you should consider panel density.

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.
