how much electricity can a tesla solar roof generate
I consider two ways to estimate the âcost of electricity.â One way would be to simply assume 10 years of annual costs amounting to $2,250 a year, or a total of $22,500. Another way of estimating the cost of electricity would be the cost of an ordinary solar system, or $21,000 as shown in the example above. So the cost of a Tesla retrofit system would be in the range of $33,000 to $37,500.
