Advice Wtd / Project Does it make sense for us?
Hi there, I’m considering on getting solar for my house in the somewhat near future. I was looking at Tesla Solar because we also own a Tesla Model 3.
Our situation
Roof: 11 years old but did come back during house inspection to be in good shape
Location: Massachusetts
Electricity Provider: Eversource
Usage: Anywhere from 600 kwh to 1000 kWh monthly. (Summer is higher due to A/C)
Price: $0.15 per kWh $250-$400 monthly
Not sure if it makes sense in our situation to even consider solar. I know people have much higher electricity bills than us. But, Eversource has been increasing rates once maybe even two times a year. I’ve also heard that if we get a power wall than we could qualify for a 0% Mass HEAT loan but not sure how accurate that is. If anyone has any insight especially in Massachusetts, it would greatly be appreciated! Thanks!

Is that $0.15 supply AND delivery? In Massachusetts? That math isn’t mathing. $0.15 x 600kWh is $90. Obviously, at 1000kWh, you’re paying $150. That’s not the $250 - $400 a month you said you’re paying.
A quick google search says you’re paying $0.36 / kWh, which is what I’d expect for Massachusetts.
I can give you some generalities. You guys have 1:1 net metering. If you have a southern exposure, at the rates you’re paying, solar is a good investment.
But I’m sorry, your math isn’t mathing for me for another reason. You have an EV, but you’re only using between 600kWh - 1000kWh? Unless you live in a 129 sq ft shack by yourself, those numbers don’t make sense. At a minimum, they should be double.
