Is this a flat roof.
Flat roof square feet per kw solar 10.
So each kw installed will.
The average system size in the u s.
As an average each kwh will be worth around 11 5p per kwh and each kw installed will yield 890 kwh every year.
Let s say on a good day you average 5 hours of direct sunlight.
A 1 kw watt system might require as little as 80 square feet of roof area for 4 typical modules.
Assuming 0 35 kwh for a 2 000 sq.
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.
The federal tax credit would drop this price to 23 409.
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.
That s about 500 550 kilowatt hours of energy per year from each panel on your roof.
At this point you can use the calculation procedure described in the previous section.
They recommended a 7 8 kw solar roof.
That brings the total cost of the solar roof to 29 173 80.
A 10 kw system may require as much as 1 000 square feet.
The us census bureau determined that single family homes have an average area of 2467 square feet.
Home the estimated electricity consumption is 700 kwh.
Multiply 5 hours of sunlight x 290 watts from a solar panel 1 450 watts or roughly 1 5 kilowatt hours per day.
A 9 45 kw solar system installed on a 1 800 square foot roof costs between 39 600 and 81 000.
A 10 kw solar system can produce between 11 000 kilowatt hours.
Which is enough to cover the average u s home s electricity usage of 10 972 kwh per year.
The active solar tiles came to a total of 22 173.
When dividing these values you obtain 0 35 kwh per square foot.
4 how does that compare to your annual energy usage.
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 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 yearly savings and income will depend primarily on the cost of electricity displaced and the of electricity used on site.
A 10kw solar installation will usually require between 600 and 700 square feet of roof space.
A flat roof solar system usually costs around 750 900 per kw to install.
