It is partly due to the prestigious tesla brand but it s also because of their superior quality.
Tesla solar panels vs sunpower.
The total cost of the fully installed sunpower system which uses the most efficient solar panels available is 50 000.
Q cells would be about 4000 cheaper 14 000 vs 18 000 before tax credits.
So clearly sunpower panels are the superior solar panels and a great product overall.
Tesla s solar roof is 70 more expensive and produces half as much electricity as a sunpower system.
This means the panels power output falls only 0 39.
However every panel is different in more ways than meets the eye it can be quite difficult as a homeowner to make the right decision.
Sunpower is giving you a bigger system that produces more power for less money with a better warranty why are you even asking about this.
This means that the amount of solar energy a tesla solar panel absorbs from the sun is higher than lower quality products.
Did you get the tesla powerwalls at the same time or after.
You also could get quotes from others as tesla is using panasonic pv modules and lower end ones others could quote you panasonic 335watt modules or lg modules.
Currently the hanwha solar panel that tesla is quoting has a 19 6 solar panel efficiency.

Use solar energy to power your home and reduce your dependence on the grid.
Sunpower solar panels are known to be the most efficient panels on the market especially now with the recent release of their 415 watt panel with it s record breaking 22 3 efficiency.
But what about the tesla powerwall.
Sunpower solar panels have a 22 efficiency rating and most chinese tier 1 producers achieve 17.
As far as solar batteries go tesla powerwalls are by far the most popular.
Purchase solar at the lowest price of any national provider with tesla s price match guarantee and take control of your monthly electricity bill.
So since the tesla solar roof tiles have been realized to not be a legitimate solar solution for the foreseeable future for the sake of this article we will be discussing tesla solar panels and not solar roof tiles.
We use around 7000 year.
As the solar industry has expanded so has the number of available brands of panels.
It is also important to consider the real world performance of the tesla solar panels with a temperature coefficient of 39.
Brands such as sunpower lg or panasonic have dominated a large sector of the market for a long time.
The q cells would produce around 6000 kwh year while the sunpower system would produce around 6600 kwh year.
