The average cost per watt of solar systems varies around the country leading to different solar system costs, and also the amount of sunlight in each location affects the system output, so you would need a different number of solar modules which directly affects the total system costs.
This section of our site shows the average cost of installing each size of solar power system in each state and county in America. It shows costs based on installations completed in 2018 and 2019. To get live pricing, request a quote from one of our top rated solar contractors. Prices shown are per watt.
Comparing Solar Proposals by Cost per kW. (System wattage = number of panels × each panel's production rating) This might be shown in cost per watt or cost per kW (remember 1 kW = 1000 watts). As an example, if a 4 kW system costs $13200, the cost per watt is $3.3 while the cost per kilowatt is $3,300.
All told, in leading states, the price drops [of solar components] and combination of incentives mean that an installed system could cost less than $10,000, a far cry from what solar was costing just a few years ago. And it means that some people are seeing payback periods of as little as 4 to 6 years.
The cost of a solar panel today is around $3 per watt, and the extra cost of installation brings costs up to $5- $6 per watt. Note: Installation costs for PV systems include both labor and the electronics needed to tie the solar array into your existing electrical system.
Cost of Solar Power In Canada 2019. The average installation cost of solar power in Canada is $3.07/Watt, or $23,000 for a 7.5kW system (specific price per province in chart below).
The current average low-end cost of solar power As of early 2019, is approximately $3.00 per watt, installed. The average sized solar panel system is 5,000 watts, so this brings the total cost to $15,000 .
HomeAdvisor's Solar Panel Cost Guide supplies average prices for energy systems per watt and solar cells per square foot. Estimate installation costs for various types of solar power panels for your roof.
The average price per watt for solar panels ranges from $2.67 to $3.43, and solar panel costs for an average-sized installation in the U.S. usually range from $11,214 to $14,406 after solar tax credits.
Cost per watt ($/W) is a more convenient way of looking at the costs of solar panels. This metric indicates costs relative to electrical power output. The cost of solar panels have decreased significantly over the last decade and are currently selling for under $0.70/W in industrial quantities.
As of January 2018, the average cost of solar in the U.S. is $3.14 per watt ($31,400 for a 10 kilowatt system). That means that the total cost for a 10kW solar system would be $21,980 after the 30% Federal ITC discount (not factoring in any additional state rebates or incentives). The cost of solar is dropping across the nation.
