Solar Panels Needed For 3000 Kwh

How many kwh does a solar panel produce per month.

Solar panels needed for 3000 kwh.

So now that we know you need to produce about 6kw of ac output we can work backwards to figure out how many solar panels you need. As of january 2020 the average cost of solar in the u s. For a 3 kw kilowatt system which is 3 000 watts you can expect to pay 3 000 for installation. Presently the range of efficiency that is how much of the sun s energy hitting the solar cell is converted into electricity averages 18 percent but can vary depending on the quality of the solar panel.

Most residential solar panel systems use between 250 325 watt solar panels. The typical homeowner will need 28 34 solar panels to cover 100 of their energy usage dependent on location and roof size. Is 2 91 per watt 8 730 for a 3 kilowatt solar system. That said there is a simple equation to calculate the amount of kilowatt hours kwh your solar panel system will produce.

But every home is unique and could use more or less power than the average home. To get these numbers we used high and low panel production ratios to calculate how many solar panels are needed on average. According to the u s. A watt is the measurement used to gauge the ideal power potential of a solar panel.

How many solar panels do i need for 1 000 kwh per month. Energy information administration in 2018 the average monthly electricity consumption for a home in the united states was 914 kwh per month or about 30 5 kwh per day and 11 000 kwh per year. In the example above you would need 24 solar panels to account for 80 of your average consumption 29 6 kwh daily usage divided by 1 24 kwh per panel. So if you have solar panels that each produce 1 kwh of power per day you would need a full 37 solar panels to fully power your home.

First it is important to note that not all solar panels are created equally. It doesn t matter if you have a 1 500 square foot roof or a 3 000 square foot roof the amount of solar panels you ll need will vary depending on your energy use. Likewise if you wanted to account for 100 of your daily kwh consumption you would need 30 solar panels 37 kwh daily usage divided by 1 24. If you select to hire a contractor to install your solar kit you should expect to pay approximately 1 00 per watt for labor wire conduit fittings breakers and other miscellaneous electrical components to complete the solar system installation.

On average a normal household will use around 37 kwh per day. That means that the total cost for a 3 000 watt 3kw solar system would be 6 460 after the 26 federal itc discount not factoring in any additional state rebates or incentives. The exact number changes depending on the specifications of the chosen panel model as well as the sunshine available at the project site. Solar panels produce direct current dc and your home runs on alternating current ac.
