What your roof actually produces here
Montgomery County averages 4.2 peak sun hours a day. A well-oriented kilowatt of panels produces roughly 1,226 kilowatt-hours a year in this part of Pennsylvania.
A typical 9 kW residential system therefore produces around 11,034 kilowatt-hours annually. At PECO’s rate of 20.0¢, that production is worth roughly $2,206 a year before any incentive.
Those are pre-shading numbers. Trees, roof pitch and orientation move them, sometimes a lot, which is why we look at your specific roof rather than quoting from a county average.
Permitting and interconnection in Montgomery County
Permits are issued by your municipality rather than the county, so requirements vary between boroughs and townships. Interconnection runs through PECO and is a separate process on its own timeline.
We handle both. Installation is typically one to three days; permits and permission to operate take longer and are the part most homeowners find slowest.
Common questions from Montgomery County homeowners
Is my utility really PECO?
Most of Montgomery County is PECO territory, but service maps do not follow county lines. Your bill names your utility at the top. If it does not match what is on this page, call (832) 263-8055 and we will check your exact address.
Does solar still make sense after the federal credit ended?
Under a power purchase agreement, yes. The credit belongs to the system owner — us, not you — which is what makes $0 down possible. For an outright purchase the math changed in 2026 and we will show you the honest version.
What happens if I sell?
A PPA transfers to the buyer. We handle the paperwork and the new owner takes over the same rate.
Do you actually install here, or do you subcontract?
We work with a network of licensed installation partners across 16 states and match you to the one that covers your address. You will know who is coming to your roof before anything is scheduled.
Montgomery County solar and rate guides
Two ways to pay for solar, and they are very different
If you buy the system
You own the equipment, you keep any renewable energy credits, and you carry the maintenance responsibility. Installed pricing varies by roof, shading and system size.
If you use a PPA
$0 upfront. We install and own the system; you buy the power it produces at a rate set in your agreement, and you only pay for what it actually generates. The system owner carries maintenance for the life of the agreement.
The residential federal tax credit (25D) ended for systems purchased after December 31, 2025.
You will still see ads promising a 30% credit that “ends December 31.” Read the date on them. If you buy a system today as a homeowner, you cannot claim that credit. What remains applies to the owner of the system — which, under a PPA, is us. SolarAmerica does not provide tax advice; talk to your tax professional about your situation.
Who you would be working with
SolarAmerica
We design your system and manage the project; installation is performed by vetted licensed partners in your area.
PECO questions
The things people actually ask
Why is PECO's Price to Compare lower than PPL's but the all-in rate higher?
Because the two numbers measure different things. PECO's supply charge is lower; its distribution charges and riders are higher. What matters to your budget is the all-in figure — your bill divided by your kilowatt-hours.
How often does this change?
Four times a year: March, June, September and December.
Can I shop for supply?
Yes. Pennsylvania is deregulated, and switching suppliers changes only the supply portion of your bill.
