When it comes to payment, those who are using solar energy will still get a monthly utility bill. Fact vs Myth: Can Solar Energy Really Power an Entire House? One of the most frequently asked questions by homeowners in regard to solar power is, “can it really power my entire house?” The answer to that is actually quite simple – yes, solar can indeed power your entire home. A 2000 square foot house will need 28- 34 solar panels, which comes out to an average cost of \$3.50 per watt. The average 2,000-square-foot house uses approximately 1,000 kWh (kilowatts-hour) of power per month, which breaks down to an average usage of 32 kWh per day. Roof leaks after solar panels are extremely rare. If you experience a large amount of lightening storms in your area, failure to ground your solar system could result in damages to your product.
