The average energy needs of a u s.
Purchase solar roof at one of the lowest cost per watt of any national provider and take control of your monthly electricity bill.
The amount of power kwh your solar energy system can produce depends on how much sunlight exposure your roof receives.
To figure out how many kilowatt hours kwh your solar panel system puts out per year you need to multiply the size of your system in kw dc times the 8 derate factor times the number of hours of sun.
If you have limited roof space the best recommendation is installing the most efficient solar panelsavailable.
Solar roof is comparable in price to a typical roof with solar panels.
Here s how many solar panels that equals.
Tesla starts with an initial estimate of 10 kw of solar generation on a 2 000 square foot roof.
It adds up to a.
Considering 6 peak sun hours per day and 300 watt panels you need 16 to produce 700 kwh each month.
This will maximize the watts installed per square foot compensating the area limitation.
California has more sunny days annually than new england.
The actual total cost of a tesla solar roof will depend on the size of your home and your monthly energy usage.
Solar roof is comparable in price to a typical roof with solar panels.
And the typical solar panel makes 320 watts of electricity in ideal sunny conditions.
Depending on where you live in the united states you probably get about 4 to 6 peak sun hours per day meaning that 10 kw system will make between 14 600 and 21 900 kwh per year.
Tesla estimates that a 10kw solar roof will cost a total of 33 950 including incentives.
The amount of sunlight you get in a year depends on both where you are in the country and what time of year it is.
For a 9 45 kw system on a 1 862 square foot roof tesla is charging 64 634 for the solar roof along with 10 050 for a powerwall and another 10 630 for roof and site repairs.
So if you have a 7 5 kw dc system working an average of 5 hours per day 365 days a year it ll result in 10 950 kwh in a year.
