What size of solar system do I need?
The first step to figuring out what size you'll need: If you're a homeowner, look at your power bill!
Looking at your power bill will tell you how much power consumption you've used. It'll tell you in Watts or kilowatts, how much power you need and that will translate into how many panels you will need.
But think about this...
- Do you plan on getting an electric car?
- Do you plan on adding a hot tub?
There is a list of things that you need to consider when you're adjusting upwards. If we talk about “tomorrow's home”, we would recomend you to get extra panels with the popularity of electric running devices. It's more of a question of not if, but when are you going to get an electric car with what a lot of these auto manufacturers are doing...
If you are a renter...
and you're thinking about buying a home and you want to add solar panels in the beginning and you don't have a history. Two things: So you can get a power bill from the current owners. It'll give you an estimate or an idea, because the energy use and how much heat or how much air is moving through the house will affect the energy consumption.
But as a basis, the average system in America right now, even, here locally (in Salt Lake City,Utah) is about seven kilowatts. That's the average size of the system. So that'll help you know what to do.

Our advice to you, is COMPARE. You know you want solar, so compare the different financing options and figure out the one that works best for you and your goals.
