In 1977, solar panels cost $76.67 per watt. But the following year, they dropped to less than $60 per watt. The year after that, they hit $40 per watt. By 1980, the panel prices had slid to just $30 per watt, and the downw ard tren d has only continued since. Today, the average solar panel costs less than $1 per watt.
Solar panels made in the United States typically cost 80 cents to $1 per watt, which is 10 to 30 cents more per watt than imported panels. Premium panels can cost up to $1.25 per watt. The price gap has narrowed in recent years, partly because of U.S. Commerce Department tariffs on certain imports by China and Taiwan.
However, solar panels are only one component in a solar power system and what we need to study is the total cost of installed residential systems. That's bringing the cost of solar power down to between 13 cents per kilowatt-hour and 17 cents per kWh, when not including federal subsidies.

The cost of solar panels is calculated using dollars per watt. In 2018, the average installation cost for homeowners was between $2.87 and $3.85 per watt. Before tax credits, the gross cost of solar panels averages to $16,800. Assuming 5 kilowatts (kW) per household, solar panels cost from $10,045 to $13,475 after tax credits are applied.
The installed cost of solar power fell to record lows in the first quarter of 2017 because of the continuing decline in photovoltaic (PV) module and inverter prices, higher module efficiency, and lower labor costs, according to an analysis by the U.S. Department of Energy's (DOE) National Renewable Energy Laboratory (NREL).
Photovoltaics. Photovoltaic prices have fallen from $76.67 per watt in 1977 to nearly $0.23 per watt in August 2017, for crystalline silicon solar cells. This is seen as evidence supporting Swanson's law, which states that solar cell prices fall 20% for every doubling of cumulative shipments.
In Utah, another very competitive solar market, where the average system size needed is 5.7 kW and the average system cost per watt is $3.00 then the average cost of an installed residential solar system is $17,100 before the tax credit and around $11,970 after the 30% solar tax credit.
As of January 2019, the average cost of a solar panel system quoted on EnergySage in the state of California was $3.03 per watt. Since the average system size in the U.S. is 6 kilowatts (6,000 watts), the average price for a solar panel system in CA is $18,180 before any local incentives or the federal tax rebate (ITC).
How to Use California Solar Statistics View Solar Statistics From the average cost per watt of a solar system, to the city with the most roof-top solar, to the total number of MW installed, the View Solar Statistics menu provides the most up-to-date information on the California Solar Initiative.
How Much Do Solar Panels Cost? Currently (as of March 2019) homeowners typically spend around $3 per watt for a complete solar panel system with installation. Considering the average home installs a 6,200-watt solar panel system, the average homeowner has an estimated cost of $18,600 to install solar panels.
For residential solar, the largest single category of soft costs is sales and marketing, particularly for third-party solar companies such as SolarCity, Sunrun and Vivint. These costs totaled $0.31 per watt for installers, but $0.43 per watt for third-part solar companies, giving these companies a $0.23 per watt premium over the typical installer.
The average solar panel system from Sunpower is 7,870 watts (7.9 kW) and costs $36,300 for a price per watt of $4.60. The expected cost per kilowatt hour (kWh) is $0.17. Most of the systems sold by Sunpower use their lease or power purchase agreement (PPA).
The roof spaced needed to install a solar panel is typically 100 square feet of roof space for every 1 kW of conventional solar panels. Ideally, the roof should have a 45-degree pitch, but solar panels will function with a pitch as low as 10 to 15 degrees and only experience a 4 percent drop in energy creation.
In short, the reduced costs of equipment and expertise have driven down the installed cost of solar to an average of $2.67 to 3.43 per watt. How can businesses bring commercial solar panel costs down even more? The average corporate campus can fit in about 500 kW worth of solar.
The cost of a solar panel today is around $3 per watt, and the extra cost of installation brings expenses up to $5- $6 per watt. Installation costs for PV systems include both labor and the electronics needed to tie the solar array into your existing electrical system.
Average cost of solar panels for homes in Washington as at June, 2019 is $ 2.95 per watt.This means that for a 5 kW residential solar system the cost is $ 14,750 before solar incentives and $ 10,325 after claiming back the solar tax credit.
The cost of solar panels is about $15,000 - $25,000 depending on the size of your solar system. For a 7.5 kW system, the cost would be about $21,000. The cost of your solar panels (including other hardware and installation) is based on an average cost per watt of $2.80.
