Since 2010, rooftop solar has grown 27x, and prices have dropped by half. More Americans than ever are switching, and incentives make it easier than ever. If you are also planning for this, NEDES’ rooftop solar installation services make it simple.
Rooftop solar panel installation designs, permits, and mounts a PV system on your roof. It connects to your home’s electrical panel and the utility grid. This cuts energy bills by 50-90%, while also boosting your property value.

Rooftop Solar Installation Deliverables
Our rooftop solar panel installation includes the full scope of work — not just panels dropped on your roof. Here’s what installation includes, start to finish:
Free roof & shading assessment (age, pitch, orientation, structural load)
Custom system design sized to your kWh usage, not a generic package
Permitting and HOA paperwork, filed and handled by us
Residential Solar Cost
As of July 2026, the national average cost of solar panels is $2.50 to $3.50 per watt installed, before incentives — putting a typical 6–8kW system at roughly $16,000 to $28,000. Remember that your actual solar panel installation cost depends on system size, roof complexity, and the equipment tier you choose; larger systems usually lower your solar cost per watt since permitting and site-visit costs are spread across more panels.
| System Size | Good For | Estimated Cost |
|---|---|---|
| 4 kW | Small home/condo | $10,000–$14,000 |
| 6 kW | Average 3-bed home | $15,000–$21,000 |
| 8 kW | Larger home / AC-heavy | $20,000–$28,000 |
| 10 kW | High usage / future EV | $25,000–$35,000 |

Solar System Installation Process
Here’s how we set up a rooftop solar system at our place, from the first call to turning the switch ON. Most homes complete this process in 4 to 8 weeks total, with just 1 to 3 days of on-roof install work.
First, we check roof condition, shading, orientation, and your electrical panel — in person or by satellite scan.
Sized to your actual kWh usage, with actual pricing — not a rough estimate.
Next, our team files with your local AHJ and HOA. This step usually takes the longest — weeks, not days.
Then come racking, panels, inverter, and wiring, which normally take 1–3 days.
Local building and electrical inspectors sign off on the finished system.
Lastly, your utility installs a production meter and switches your system ON.
Make A Right Choice!

State Incentives
Permitting timelines and incentives differ from state to state. Pick yours for a location-specific note.
Grants up to $7,500 for income-eligible homes through the state's solar program, plus SRECs, a 6% sales tax break, and property tax exemptions — though this year's funding round has already closed.
No cash rebate here, but full retail net metering, SREC income, and a property tax exemption on the added home value make solar pencil out even without one.
Your home's added solar value is 100% exempt from property tax, and while there's no statewide net metering, many utilities offer their own buyback rates — Austin Energy included.
Mandatory 1:1 net metering at retail rates plus an active SREC market (roughly $22–$40 each) do the heavy lifting here. Philadelphia adds a modest per-watt rebate when funding allows.
Home to the country's best SREC prices — often $360–$400 a credit — alongside full retail net metering and a low-income solar program that currently has a waiting list.
The toughest state for solar incentives: no tax credit, no SREC market, just a utility buyback rate around 7 cents per kWh and the occasional co-op rebate.
A full property tax exemption on residential systems pairs with Duke Energy's PowerPair rebate — up to $9,000 for solar plus battery — and retail-rate net metering through Dominion.
Delmarva customers can claim a rebate up to $6,000, on top of full retail net metering and a reliable SREC market paying around $30 a credit for a decade.
