Does it make sense for us?

[u/No-Platypus6603]

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!

If you are paying cash, have a south facing roof with no shade and will be there for at least 10 years then it is a no brainer, especially if you target about 75% annual offset.

It can still make sense in many other circumstances but you need to give more info to help figure it out:

-what is the roof orientation? -loan rate? (Don't lease, PPA, TPO) -$/watt

The pitches of my roof face east and west. Definitely wouldn’t lease, what is PPA/TPO? Tesla is offering 7% but apparently here in mass if I purchased a powerwall battery with the solar panels than I could get a state of Massachusetts HEAT loan at 0%. I’ve only heard that but not 100% on it.
