Solar panels are the best way to save on energy costs in San Diego, CA, but how much do you need? Probably the most important aspect of designing your home’s solar power system is to ensure you are able to produce enough power to be self sufficient and eliminate your electric bill.

With that in mind, It’s a good idea to avoid spending more than necessary to produce the power you need. Many factors can affect this like available roof space and the average amount of sunlight at your home. If space and sunlight are scarce, then you will need a high performing panel.
