A 9 45 kw solar system installed on a 1 800 square foot roof costs between 39 600 and 81 000.
Flat roof square feet per kw solar 10.
Or a residential sloped roof.
In addition to attachment issues the most optimal rooftop areas for solar were also the most visually prominent with the homeowner voicing concerns over the aesthetic.
Of the 15 000 square feet of roof space roughly 12 000 square feet is covered by standing seam metal roofing while the remaining 3 000 square feet are covered by tpo.
In order to calculate the below data we averaged annual kwh production in the top 12 solar states and assumed standard 250 watt panels in order to calculate how many panels you would need.
Is this a flat roof.
Which is enough to cover the average u s home s electricity usage of 10 972 kwh per year.
4 how does that compare to your annual energy usage.
Home the estimated electricity consumption is 700 kwh.
This will greatly impact how you mount the panels and how many you can fit on your roof.
A 1 kw watt system might require as little as 80 square feet of roof area for 4 typical modules.
A 10 kw solar system can produce between 11 000 kilowatt hours.
A 10kw solar installation will usually require between 600 and 700 square feet of roof space.
The active solar tiles came to a total of 22 173.
So each kw installed will.
A flat roof solar system usually costs around 750 900 per kw to install.
At this point you can use the calculation procedure described in the previous section.
The us census bureau determined that single family homes have an average area of 2467 square feet.
That brings the total cost of the solar roof to 29 173 80.
When dividing these values you obtain 0 35 kwh per square foot.
They recommended a 7 8 kw solar roof.
As an average each kwh will be worth around 11 5p per kwh and each kw installed will yield 890 kwh every year.
That s about 500 550 kilowatt hours of energy per year from each panel on your roof.
The yearly savings and income will depend primarily on the cost of electricity displaced and the of electricity used on site.
The remaining 1 293 square feet of roof space would be covered in tesla s inactive shingles coming to a cost of 7 240 80.
A 10 kw system may require as much as 1 000 square feet.
The average system size in the u s.
Is 5kw 5000 watts so you can use that as a benchmark if you re unclear on what your power needs will be.
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.
The federal tax credit would drop this price to 23 409.
If your area is limited you might consider using more efficient solar modules which provide more watts unit of area but cost about the same per watt.
