How many solar panels are needed to run a 4,000 square foot or larger house?

If you have a very large house, you probably have high electricity usage too, possibly making your home a good candidate for solar.
If you’re curious about solar and want to find out how many solar panels you’d need for your home that is 4,000 square feet or larger, the most accurate way to find that out is to get a professional solar installer to perform an analysis. A quick but somewhat less accurate way is to read your monthly electric bill and use our solar calculator to determine what your power generation and estimated system price would be.
