In Maryland, cost of 1 kWh is about 10 cents. So, if you produce 100 kWh/month and use 100 kWh/month, you pay nothing because you produced what you need. If you produce 150 kWh in a month, the 50 kWh you sell back to the power company is 5 cents per kWh. You are not getting the 10 cents the power company is charging you. Hope this makes sense. |
SDGE is closer to 50 cents per kWh. Looking to do the same as OP. |
SDGE is .57 per kWh for on peak which is 4pm-9pm. It's insanity. We don't even the AC on until 10pm just so we can sleep comfortably and our bill is still $500 a month. |
I installed a $30K system in DC a few years ago. It produces about $150 worth of electricity each month, and about $500 worth of SREC's -- Solar Renewable Energy Credits. As you say, with the 30% federal credit the installed cost was about $21K. It paid for itself in a little over three years, since then it's been generating about $7000 a year in income. The value of the SREC's has gone down slightly but the cost of electricity has gone up. |
Can you explain what you mean by this - "generating $7K annual income"? |
I did know the answer to the penny. We set to 80, turn it off during the day and it's $550, only $40 was gas (stove, tankless water heater). Last fall there was the gas price spike and we were going over $1000 while hardly using the heat. I want all electric appliances, heat pump, a hybrid vehicle and solar with storage. The issue for us is we need some electrical upgrades, and have a handmade tile roof. I want an induction range, simply because I've hated the last two gas ranges I've had (previous house and here). |
The SREC's are cash, they show up in my checking account by direct deposit, about $5K a year. I haven't paid an electric bill in five years, before I got solar I was paying $150 a month or $1800 a year. That's also money in my pocket, albeit indirectly. Together I am about $7K a year richer. The panels are paid for. |
NP. The SREC (solar renewable energy credit) market in DC is the strongest in the country. for every megawatt of solar I generate, I get paid approximately $400 for a SREC, because pepco gets fined $500 per megawatt for failing to source ~15% of their power from renewable energy within the district. (which is less than 10 square miles of space to generate solar, in a densely built-up landscape.) In maryland and virginia, a SREC is around $50. In the rest of the country most of the payback is going to be in reducing your energy bills. So my system should generate about $8000/year in SREC credits, and reduce my annual power expenditures by about $3500 a year based on what I paid last year, thus my solar panels will be paid off in a few years. |
Wow! I had no idea. So dumb question here - is this considered taxable income? |
The IRS hasn't ruled on SREC's. You don't get a 1099. The avoided cost of electricity wouldn't be considered taxable income. |

I bought solar panels for my small house a couple of years ago (late 2020). They were about $10K before state/federal rebates. I bought through a solar coop that is supposed to provide lower costs for participants.
https://www.solarunitedneighbors.org/maryland The solar company estimated it would take me about 7 years to recoup my investment, and that seems about right. Since I've had the panels I only pay about $9/mo for electricity (that's fees to Pepco) and I've earned about $900 in SRECs. I also needed to get my roof replaced for the installer would put the panels on. Your roof needs a certain amount of years of life left, and mine was well past that. I would have needed to replace my roof anyway, so this just sped up my timetable for that. I'm happy with my panels. However, I also think that they're not worth having if you can't buy them outright; the finances only barely make sense if you own them, and the benefits are really not there if someone else is getting all the tax breaks and you're having to pay a leasing fee every month. If you want to get them to "save the earth," then honestly, there are better and cheaper ways to do that. I also think that they work best if most of your house runs on electricity. I am considering switching to a heat pump, for example (currently I have a gas furnace.) I'd also like to get an induction stove and an electric dryer. But those changes are expensive so I haven't done that yet. Again, I am happy with my panels, I'm not sorry I got them. But realistically, I'm not maximizing their benefit to me yet. |
OP here - thank you for this, I appreciate you sharing the pros and cons. It does seem like buying is the way to go, if we're going to go solar. |
| We put panels on our DC row house (flat roof) and it’s been great. We paid for them up front and got the tax break, and then have been getting about $300 in SREC payments every month (along with almost nothing in electric bills). It’s a big outlay upfront but I’m a fan so far! |
| What about Virginia, anyone? (Arlington in particular?) |
| It’s worth it if this is your forever home. ROI takes years if you buy them and a little risky since leasing is long term like 25 years. |
