As an estimate if you need 2 000 square feet of roofing on your home a tesla solar roof will cost a little less than 44 000 according to tesla themselves.
Sq ft needed for 8 kw solar on roof.
And the average solar power system needed is a 5 kilowatt system.
You will need a roof space of about 340 sq ft for a 5kw system.
According to tesla the average tesla solar roof cost a property owner can expect to pay is around 21 85 per square foot this estimate was made based on a roof made of 35 percent solar tiles.
Here s a general example.
Divide the result by the average square footage of one panel.
Household is a 6 62 kw solar system to match the 9 000 kwh of average energy usage by u s.
A tesla solar roof costs 22 to 45 per square foot which includes the solar roof tiles a powerwall roof and site repairs and complete system installation.
How many solar panels do you need for a 2000 sq.
Let s say you have 600 square feet of sun facing roof.
Tesla solar roof cost.
Ft so most homeowners will have more than enough room for solar panels.
The typical homeowner will need 28 34 solar panels to cover 100 of their energy usage dependent on location and roof size.
The average energy needs of a u s.
However you can use the same procedure to estimate how many are needed.
System size kw square footage needed for low efficiency 16 square footage needed for medium efficiency 18 square footage needed for high efficiency 22 5 kw.
A 10kw solar system which consists of 40 panels can produce an average of 14 000 kwh per year.
600 75 450 square feet available for solar panels.
Number of solar panels per square foot of roof space.
Each solar installer has sophisticated software that can spell out your house s exact power needs while looking at historical weather patterns roof angles and other factors to tell.
That s enough for the average 21 panel 6 72 kw system.
This size of solar panel layout will only take about 350 400 sq.
450 17 6 25 panels would fit on your roof.
Most u s homes have rooftops that are about 1 500 sq.
For example if the amount of power needed is 5 000 watts and each shingle is rated at 50w you need 100.
To get these numbers we used high and low panel production ratios to calculate how many solar panels are needed on average.
But at 20 watts per square foot a system rated to produce 2 kilowatts would cover roughly 150 square feet while a 3kw system would take up about 225 square feet.
Solar shingles are smaller than panels and their wattage is lower as a result.
Most residential solar panel systems use between 250 325 watt solar panels.
Tesla solar roof cost.
Now take your 450 square feet and divide by 17 6.
A 9 45 kw solar system installed on a 1 800 square foot roof costs between 39 600 and 81 000.
