How much does it cost to power a house with solar panels
To find out how much it costs to power a house with solar panels, you need to find out how much power the house uses. Solar power systems are sized in watts, the more watts of power it takes to power the house, the more it will cost to power the house with solar panels. According to the Solar Action Alliance, the national average is $3.00 per watt. But some companies, including Freedom Forever, have been able to go even lower than that. A lot depends on how ready your home is to go solar
How much does an average solar system cost?
The average system sold in the U.S is a 5-kilowatt system. The average installed cost of a system, which includes the full cost of parts, installation, and permitting, is $3.00 per watt. If you multiply 5,000 watts by $3.00, you can see that the average system costs $15,000 before any credits or tax rebates. The Federal Tax Credit for solar power can reduce your cost by up to 30% of the installed cost of your system.
Larger systems cost more. For example, a home that uses an average of 12 kilowatts would need a system that costs $36,000 before tax credits and rebates. However, the more power you use, the more money you save by going solar. Thus, if you pay very high electric bills, you benefit more by going solar.
How much does it cost to power a house with solar and batteries?
Batteries will add significantly to the cost of a solar system. A Tesla Power Wall costs about $3,000 before installation costs. You will also need a special inverter. Home batteries are typically warrantied to last 10 years. Thus the batteries would need to save you an additional $250 per month just to cover their purchase price
If you live in an area that is served by utilities that charge high peak, Time-of-Use (TOU) rates in the evening, batteries make sense. They enable you to power your house by using the batteries during those high peak rate hours. If you live in an area that is served by conventional fixed rates, then you probably won’t save enough to justify the cost of the batteries.
Batteries may also make sense if you have critical power needs and are subject to frequent blackouts. Inverters for battery powered systems often enable you to choose to provide power to selected circuits during blackouts
Does it make sense to go solar in all 50 states
Yes, it makes sense to go solar in all 50 states. Thanks to how long solar panels last, you’ll recoup your investment in every state. In states like Massachusetts and Hawaii, you’ll recoup the cost of going solar in about 4 – 5 years, thanks to generous state-level incentives. In Arkansas, where power is less expensive and there are less subsidies, it could take up to 20 years to recoup the cost of your system. But even in states like Arkansas, the cost of electricity continues to rise year after year. By going solar, you lock in a fixed rate for the electricity you are buying. Thus your decision to go solar saves you more money every time electric rates rise!
