Solar
Home solar, done once and done properly
Solar only pays off if the system is sized for how you actually use electricity and installed on a roof that will outlast it. Both are things we check before quoting, not after.

How the process runs
A site survey confirms shading, roof condition and electrical service capacity. Design produces a panel layout and a production model. Permitting and utility interconnection run in parallel, and they are usually the longest part of the wait rather than the installation itself.
What we look at first
Your usage over a full year, not a single bill. Summer and winter pull differently, and sizing from one month is the most common way a system ends up wrong.
What else should I know about solar?
Cost and financing
Cash, loan and lease compared honestly.
Roof and solar together
How roof condition can affect Solar planning and the order of work.
Battery storage
What battery storage may support during an outage and how stored electricity can be used later.
EV charging
Level 2 charging, what the panel has to support, and what the run to the parking spot costs.
Service for existing systems
Including orphaned systems where the original installer is gone. You do not need to have bought from us.
Panel removal and reinstallation
What it involves, why it costs what it does, and how to avoid needing it at all.
Installation and project preparation
What installation day, electrical upgrades, meter changes, and site work can involve.

Our solar and roofing installation and service teams are SunnyMac employees across Delaware, Maryland, New Jersey and Pennsylvania, and our heating and cooling teams across Delaware, New Jersey and Pennsylvania — which is why one company can sequence a roof and a solar system together instead of coordinating two.
Which state are you in, and what changes?
Solar economics are set at state level. These are the four we install in, with the figures that differ between them.
| State | Typical time to a powered system | Average electricity rate | SREC value | Incentive programs |
|---|---|---|---|---|
| Delaware | 15 weeks | $0.16 per kWh | Market-based, no fixed rate | Delaware programs |
| Maryland | 19 weeks | $0.17 per kWh | Market-based, no fixed rate | Maryland programs |
| New Jersey | 18 weeks | $0.18 per kWh | $77 per MWh | New Jersey programs |
| Pennsylvania | 19 weeks | $0.17 per kWh | Market-based, no fixed rate | Pennsylvania programs |
Time to power is the median from signed agreement to a system producing, measured on our own completed installs. An SREC is one certificate per MWh generated; where the rate is market-based it moves, so we publish the range on the state page with the date it was checked rather than a single number here.
