How much do solar panels cost? This is undoubtedly the question we`re asked the most, and unfortunately it has no straightforward answer. We decided to pull together all aspects of this question, and write the best resource on the costs of solar panels you will find on the entire Internet.
Residential solar systems are typically sized from 3 to 8kW and end up costing between $15,000 and $40,000. The cost per watt (price inclusive of parts, labor, permitting fees, overhead, and profit) has decreased significantly over the last decade and is now between 6 and 8 ($/W) in many parts of the U.S. Generally, the bigger the system, the lower the cost per watt.
Let`s start by evaluating the solar system costs for a single-family home in Los Angeles, California. To make things simple, this family chose to pay for their solar system in cash – you`ll learn more about other ways to finance a solar system further down on the page.
In order to supply 70% of the household`s electricity consumption, 5,600 kWh per year, we decided to install a 3 kW solar system on their roof.
5,600 kWh is the equivalent to:
6,000 lbs. less in carbon emissions
Planting trees on half an acre
Not driving your car for 7,500 miles
The calculations below are based on the following assumptions:
Electric bill of $100 per month
Cost per watt at $6.50
Electricity rate at 14.78 cents per kWh
Annual growth of electricity rate at 2.8%
These numbers are all based on recent data from credible sources
