What is your solar system setup? Who makes it and what was the total installed costs? Curious!
5.79kw system. Got a SolarEdge inverter (Enphase is the other major manufacturer), and I think JinkoSolar 310w panels. Not sure what kind of racking system I have.
Modern Mill solar installed it. They're out of Fort Wayne, and have offices in Grand Rapids, Detroit, Chicago. Prices with solar is tough; it's always getting cheaper. Modern Mill had a solar loan program with a 30yr loan that was as competitive as my mortgage rate. This made the monthly solar loan cheaper than my average electric bill. I also received a 30% tax credit. The total system cost was like $27k (before 30% tax credit). Keep in mind this was 3-4 years ago. I suspect Modern Mill purchases interest rate point discounts to get rates as low as they do. At the time, unsecured loans were like 8-9%, 30yr fixed rate was 3.49-3.99% and my solar loan was 3.79%. After receiving the tax credit, I paid down the loan.
If you are comfortable with roofing, you can install your own array and save a ton. Just need to hire an electrician to hook it up. Half the cost of my array was labor. There's tons of wholesalers that sell kits.
Totally worth it. Even on overcast days like we've had recently, I can produce over 25kWh. A Model Y battery is 75kWh. So even on overcast days I can produce more than 110mi of range. Peak summer days I can produce around 43kWh. 110mi of range could be 2-4 gallons of gasoline; you could argue I'm saving $10-20 in gasoline costs. But I'm really avoiding paying electric costs of 25 x .07 = $1.75.
Net metering and time of use rates work in my favor. The grid is my battery, essentially. Consumers Energy pays me for excess energy, at the time of use rate. During peak periods, I generate more power than I need, even in summer. They pay 15c/kWh for it. Then I charge at midnight during super off peak period at 7c/kWh. You're able to take advantage of a little arbitrage.
IMO, it is worth it. Utility rates never get cheaper. The more they increase, the faster the system pays for itself. Switching to an EV just helps pay for the array that much quicker.
Call around and get some quotes. You will be surprised at the amount of options out there. You don't have to get a solar loan like I did. I just wanted to outright own the system and it's output.
Worth knowing; your system size will be limited by the utility company. It can't be larger than 110% of your last 12 months of energy use. Knowing this, I had a extra larger inverter installed (it could support a system almost twice as large). This gave me room to add to the system, without buying a new inverter (inverters are one of the most expensive components in a solar system). This stinks if you are planning on adding a couple EV and pool in the coming months / years, but want a solar array now. I still produce more than I consume, but it's only because of night time charging. If I charged during super peak periods, I would quickly deplete my net metering credits.
