4 FAQs about Solar energy storage station cost per watt

How much does a solar system cost?

A fully installed solar system typically costs $2.50 to $3.50 per watt before factoring in incentives like the 30% tax credit. Using this measurement, a 6,000-watt solar system (6 kW) would have a gross cost between $15,000 and $21,000. The price per watt for larger and relatively straightforward projects are often within the $2.50 to $3 range.

What is the relative cost of solar energy?

Another measure of the relative cost of solar energy is its price per kilowatt-hour (kWh). Whereas the price per watt considers the solar system's size, the price per kWh shows the price of the solar system per unit of energy it produces over a given period of time. Net cost of the system / lifetime output = cost per kilowatt hour

How much does solar cost per watt?

The price per watt for larger and relatively straightforward projects are often within the $2.50 to $3 range. Claiming incentives like tax credits and rebates can bring the PPW even lower. However, the following factors may push your solar price per watt into the $3 to $4.50 range.

How many kilowatts does a solar system use?

Solar systems are sized in kilowatts (kW) and are typically designed to offset 100% of your average annual electricity usage. For reference, the average U.S. household consumes 10,000 kWh of electricity per year and, with average sunshine, would need a 7.5 kW solar system to offset its electricity charges. Is the price of solar panels falling?
