MD Flag is the Best Flag Installed solar, my power bill was $8.94 (again)
1 month later update, I made a post last month about my March bill being $8.94. My April bill is also $8.94.
We flipped on central AC sometime early April and use a window unit to cool down the master. We usually set the AC to 65 or so for a few hours to cool down the house at night (upper levels are very hot).
Since for whatever reason most of the bills in this subreddit don't have hard numbers, here are my hard numbers
- Credit from last bill: -112
- Current month usage: 757
- Current month excess: -1058
- Total kWh balance: -413
Pepco Usage summary and charges
I don't have a consumption meter, but April we generated 1.7 MWh.
Someone smorter than I can probably interpret these numbers in more detail, I'm just a solar-stan.

It’s your fixed, monthly customer charge.
Everyone pays that no matter how much electricity you generate or consume. It is the same every month. Mine is about $9 on BGE.

What’s your anticipated break even timeframe for the installation of solar? I can’t get over the upfront cost. Feels like I’m just prepaying utility bills.

u/md4pete4ever 23d ago
I installed Solar 12 years ago (Solar City at the time). They own the panels (and repairs/upgrades) and I prepaid 20 years of guaranteed generation. Payback time was ~7 years. Someone's estimate on OP's numbers is payback in ~5 years.

u/HappyStalker 23d ago
How often have you had them repaired or upgraded in those 12 years?
23
u/md4pete4ever 23d ago
One time a fews years in - initiated by the company (Tesla bought out Solar City). Had squirrels get interested in the wiring and chewed through something so the panels were offline and not generating. Company came to investigate, figured out the problem, and then took ~6 month to design a solution and install (wire fencing guards around the edges of the panels). They also swapped the panels out for a more efficient model. We got a rebate check from them for the energy that wasn't generated that year, so no real impact to us.

u/LetThemEatVeganCake Silver Spring 23d ago
No impact to you, so does that mean you didn’t have to pay for the new squirrel guard?

u/dihydrogen_monoxide 23d ago
I had those added with initial install.
Lumina requires them

u/md4pete4ever 22d ago
I think we were relatively early with solar installation and the industry hadn't figured out that they need to have those.

u/dihydrogen_monoxide 22d ago
There was a story last week about squirrels making a nest under a panel that caught fire

u/md4pete4ever 22d ago edited 22d ago
I didn't pay anything for the repairs and upgrades because Tesla owns the panels. I pre-purchased a certain amount of power generation each year. Any short fall in generation means they send me a rebate check.

u/lowlybananas 23d ago
We've owned our solar panels for 11 years and haven't had to repair anything.

u/horse-boy1 23d ago
I installed 3kw myself in 2007, much easier to do back then. I had the inverter go bad 10 years ago and I replaced it myself. It was going to cost almost as much to repair it than a new one! I also had a couple of leaks, so I removed the panels fixed the issues and reinstalled them.
My pay back was around 7 years. There was a state grant of $5k and Federal tax credits which helped.1

u/blupanteez 23d ago
If you have the cash and you consider the return on a bank CD, owning solar is the better deal.

My husband thought I was nuts, but even his calculations showed it made sense.

u/dihydrogen_monoxide 22d ago
Technically it would be bank CD return - (sum of electric bills for the year). My power bill is high enough that it basically negates most if not all cd gains and I'm still in the negative.

u/Big-Location3986 23d ago
I have solar and get a $10 bill every month. Just fees for being connected to their grid. I also got a $150 check from them too when the overage cashed out last. And zero grid consumption over the past year too.

u/harvey6-35 23d ago
I think the $8.94 is an account charge. If you sign up for Pepco energy wise awards, you'll have no bill from March/April until Novemberish.
My bill was about $6 but I have an electric car and a long commute that uses my previous surplus power. But I did also get $37 in SRECs to balance out last month.

u/on_island_time Montgomery County 23d ago
Love it, can you share a general location (even just county) and who was your installer?
We're on Potomac Edison and when I've looked into solar in the past, it wouldn't save us substantially on our bill. Which frustrates me and I'm hoping won't always be the case.

I wish. We live in Delaware. Last month we put 235 kWh into the grid. Our bill was $41.

u/Fit_Roll_5348 22d ago
You save everywhere else in taxes, so just evening things out with other states in cost of living

u/da6id 23d ago
Pepco has an $18 monthly customer service charge even if you are net exporter to the grid for the month. Your provider likely similar

u/Long-Time-Coming77 22d ago
OP is serviced by Pepco and the monthly charge is $8.94 when you include taxes/fees.
You can see it clearly if you look at the attachments OP included

u/mollymalone222 23d ago
Just asking, your electric bills seem so high to me. I've never had one over $200. Is that the new norm? Thx.

u/LetThemEatVeganCake Silver Spring 23d ago
They could have an EV/EVs. We have two EVs. For our April bill cycle, we used 980kwh to charge and 682kwh for our house (total bill minus data from the charger). Our electricity bills obviously got significantly higher when we switched to EVs, but we used to have to pay for gas.
Edit to add: it is also annoying because Pepco ends up sending us tons of emails saying we use way more electricity than similar houses. They know we have two EVs because we have them linked to Pepco for charging to happen on lower-stress times for the grid, but they harass us anyway lol

u/dihydrogen_monoxide 23d ago edited 23d ago
Inefficient house really, we both work from home. If the AC is 73, upstairs is 78. So we set it to 68 for big cool days, with window unit on for the master which is a huge energy hog.

We went solar last year, and I would highly recommend it to anyone who has the means to do so.
Happy to answer any questions as well.

u/ImportantSun735 22d ago
What company did you use for install ? Ballpark cost and how do you rate the company, own or lease??
1
u/CingKobraJFS 22d ago
We own ours, it’s a 14 panel array. Cost was around 17k but after fed, state, and local rebates be paid about 5k net.
Used a company called Standard Energy Solutions based out of Columbia. They were pretty good to work with, not trying to constantly upsell us.

Here are my financial calculations
Installed System: 40 x Hyundai 440w panels with Enphase micro-inverters
- System cost (cash price) $42,966
- Federal tax credit $12,890
Net Cost $30,076
25-year warranty on the solar panels and Enphase micro-inverters.
10-year warranty on the Enphase monitoring equipment.
Previous 12 months Pepco bills = $3800** (19600 kWh total consumed)
System annual estimated production 21400 (110% production)
SREC income* = $700 per year (21 MWh x $22 x 1.5)
Break-even without including opportunity cost = 6.6 years
Break-even including risk-free interest rate of 4% on $30k compounded annually = 9.8 years ($44200 total)
Note that this does not include any income from selling excess generation back to Pepco during annual true-up and does not factor in any increases in electricity rates, both of those will accelerate break-even
*SRECs currently at worth ~$45 each but the value should drop to $22.50 by 2030. There is a 1.5 multiplier in effect for solar systems installed between July 1, 2024 – January 1, 2028. I am using the more conservative $22 figure here.
More details on SRECs: https://www.srectrade.com/markets/rps/srec/maryland
**I was signed up with a 3rd party electric supplier for most of those 12 months so my electric supply rates were lower than the Pepco SOS rate. Third-party electric suppliers are no longer available in Maryland due to legislation so I would expect to pay more than $3800 for the same 19600 kWh now

It feels like solar is getting cheaper is that true? I feel like i remember break even used to be like 20k. I think it could be good for a new administration that brings back alot of the solar subsidies and when solar is even cheaper
1
u/Long-Time-Coming77 22d ago edited 22d ago
I haven't followed it closely but I was surprised when I got serious about it last year and saw how much the panels themselves have dropped in price (and increased in output), a typical top-tier panel costs about $200
Unfortunately the cost of the materials is probably about only half the total project cost when you have it done professionally - there is a substantial amount of paperwork involved (interconnection agreement, permitting) and of course labor.
Probably there was more padding last year with the tax credit expiration looming.
It would be great if the federal solar tax credit comes back when a new administration takes office.
One of the benefits of Maryland is that we have true 1:1 net metering so any excess electricity you push to the grid is credited against electricity used later (e.g. at night) so there is no need to install expensive batteries - the grid basically acts as a battery for free.

u/I_love_manatees 23d ago edited 22d ago
Does you system use the Enphase platform? If so you can connect online see more details about your production and consumption.
For example this is my April data.
Edit: I'm also happy to answer questions or provide more data if anyone is interested.
Edit 2: because size does matter, I have 28 panels.

u/Sumotron 23d ago
I’m envious. I have 49x 435W panels and the same inverters, but mine are all east and west facing.
2
u/Long-Time-Coming77 23d ago
Wow 49 panels is a lot.
Do you ever wonder how much more production you could get with the IQ8AC or IQ8HC?
The latter was an upgrade for me for an additional $40/panel and I didn't think it was worth the extra cost but seeing my panels max out at 326/327 for hours a day makes me wonder how much more I could have gotten with the IQ8HCs
2
u/Sumotron 23d ago
Nope. My task list only grows and neither my brain nor my mind get a break. I’m happy we got the system installed last year, and when they come out with the plug and play bidirectional charger we will get that and a “cheap” EV to offset gas costs and give ourselves backup capability. Plus we generate much more than we use.

u/dihydrogen_monoxide 23d ago
You have a consumption meter
2
u/I_love_manatees 22d ago
That comes with the micro inverters (I think) - maybe you also have access to it and don't know ? You can ask the company that installed your panels if there is a monitoring system to see your production/consumption. You can ask them directly about Enphase I guess, it's pretty common.
1
u/dihydrogen_monoxide 22d ago edited 22d ago
It doesn't, it's a CT added in to the box. Enphase sells it separately (they keep sending me ads for it).
It gives you more info but in the end it's more of a nice to have than a necessity.
1
u/I_love_manatees 22d ago
Ok ! I totally agree that's it's "nice to have" but not a necessity. I'm a numbers nerd so I love it
Also you might want to look at your Pepco account. I know I have the option of downloading my consumption data (regardless of going solar, I've had this option for years). But again, I don't know if it is specific to certain meters or something all the customers have access to.

Does anybody know how much it cost to have the panels removed in order to have a new roof put on and then reinstall? Only reason I didn’t do the solar panels years ago because my roof was old and I’m waiting to replace it first. Thx

Cost me $120 per panel last Summer. 22x panels total. Insurance covered it as I had to replace a 12 yrs old 3-tab asphalt roof with hail and wind damage. New roof even lowered my premium afterwards.

u/Pleasant_Flatworm866 22d ago
Congrats. I'm still waiting for Tesla to re-install my system after an addition. Maddening.

I have owned solar since 2019. My roof does not leak. They have worked with no problems. I’m very pleased. If I were to sell my house and somebody objected to having free power, they would be fools. I charge my electric car for free. I pay nothing for gasoline. (If I have to take a road trip say to the beach or out of state I’ll rent a car.)
That is a savings of $2000 a year tax-free.
Electric vehicle cost, used: $ 10,000
Cash Cost of installation, without battery, after credits/ rebates:$30,000
Fuel costs at $5dollars a gallon annually: $3380
Old annual cost of electricity 2025: $3600
New annual cost of utilities, 2025:$ 108
Annual savings,which is tax, oasdi free:
