How much do solar panels cost per watt?
Expect the cost per watt to be between $2 to $3. As of publishing, the average cost per watt is $2.84. Solar panels typically pay for themselves within 5 to 15 years. It all boils down to how much you’re paying for each unit of power, according to Robert Flores, a solar expert at The University of California, Irvine’s Clean Energy Institute.
How to calculate solar cost per watt?
To calculate solar price per watt (PPW), divide the cost of the system (in dollars) by the size of the system (in watts). PPW = System cost / System wattage. Since solar systems are typically sized in kilowatts (kW), you'll have to multiply by 1,000 to convert to watts.
What is the average price per watt for residential solar projects?
According to the Solar Energy Industries Association, the average price per watt for residential solar projects was $3.27 in the first half of 2023. For example, the PPW of a 5,500 Watt system looks quite different before and after accounting for the 30% tax credit.
What is the current cost of a solar PV system?
According to NREL Senior Financial Analyst David Feldman, an entire utility-scale PV system now costs around $1 per watt. This significant cost decline is largely due to an 85% reduction in module prices, with modules alone costing around $2.50 per watt a decade ago.
How much does a 5000 watt solar system cost?
A fully installed solar system typically costs $3 to $5 per watt before incentives like the 30% tax credit are applied. Using this measurement, 5,000 Watt solar system (5 kW) would have a gross cost between $15,00 and $25,000. The price per watt for larger and relatively straightforward projects are often within the $3-$4 range.
How do you calculate wattage of a solar system?
To calculate the wattage of a solar system, you divide the cost of the system (in dollars) by the size of the system (in watts). PPW = System cost / System wattage. Since solar systems are typically sized in kilowatts (kW), you'll have to multiply by 1,000 to convert to watts. For example, a 5.5 kW solar system is equivalent to a 5,500 Watt solar system.
