How much would it cost estimate to install a solar system for a house? With installation, an average residential 5kW size system costs between $3 and $5 per watt, according to the CSE, which results in the $15,000 to $25,000 range. That cost is before any tax credits and incentives. If you know your current energy usage, you can calculate how much you’ll need to pay for solar panels.
Can I install my own home solar system? If you can drive lag bolts and assemble prefabricated parts, and if you’re willing to spend a day or two on your roof (or not, if you’re mounting your panels on the ground), you can install your own solar system. You don’t have to know how to hook up the solar panels to your household electricity or the utility grid.

Is solar for your home really worth it? Recently, the National Renewable Energy Laboratory (NREL) found that for a home with a solar power system, every dollar saved on energy increases a home’s value by $20.
