The Short Version
Solar panels lower your electric bill, shield you from rate increases, and add value to your home. They also require a roof in decent shape, a meaningful upfront commitment if you buy, and realistic expectations about winter production. Most homes in PA, NJ, and DE are good candidates. Some are not. The rest of this article explains how to tell which group yours falls into.
Pros: lower electricity costs, protection from rate hikes, SREC income, higher home value, long equipment lifespan, minimal maintenance, energy independence.
Cons: upfront investment if purchasing, roof and shading requirements, lower winter output, no power during outages without a battery, not ideal for short-term homeowners.
Why This Question Is Harder to Answer Than It Used to Be
A few years ago, the pros-and-cons conversation was simpler. The federal tax credit knocked 30 percent off the price of a purchased system, electricity rates were lower, and the math followed a predictable script.
Two things changed. The residential federal tax credit (Section 25D) expired on December 31, 2025. And electricity rates across the PJM region jumped harder in two years than they had in the previous ten. PSE&G customers in New Jersey now pay around 26 cents per kWh all-in. PECO customers in southeastern Pennsylvania pay around 20 cents.
Those two changes pull in opposite directions. Losing the tax credit made buying solar more expensive. Rising rates made every kilowatt-hour of solar production more valuable. The net effect depends on your utility, your usage, and your roof, which is exactly why a generic answer is worthless and an honest breakdown matters.
The Pros of Solar Panels
Your electricity gets cheaper, and it stays cheap
This is the core of the whole argument. When you produce your own power, you stop buying that power from the utility. At 20 to 26 cents per kWh across our region, the electricity a solar system generates is worth more here than in most of the country.
And unlike utility rates, the cost of solar electricity does not move. It is set the day the system is installed. PECO can phase in another round of PJM capacity costs. PSE&G can absorb another BGS auction. Your panels do not care. The power they produce next year costs the same as the power they produced this year, which is to say, nothing beyond what you already committed.
You get paid for production, not just savings
Pennsylvania, New Jersey, and Delaware all run programs that pay solar owners for the energy their systems generate, separate from bill savings. New Jersey’s SREC-II program through the ADI pays a fixed rate per megawatt-hour, locked in for 15 years. Pennsylvania’s SREC market lets owners sell credits at market prices. Delaware runs a competitive SREC procurement with 25-year contracts.
This is income on top of avoided electricity costs. Most homeowners researching solar do not realize it exists until an installer walks them through it.
Your home is worth more with it
Multiple national studies, including research from Lawrence Berkeley National Laboratory and Zillow, have found that homes with owned solar systems sell for a premium over comparable homes without them. In New Jersey, the added value is exempt from property tax, so the equity gain comes without a tax penalty.
The equipment outlasts almost everything else on your house
Modern panels are warrantied for 25 years and routinely produce beyond that. There are no moving parts. Maintenance amounts to occasional cleaning and an annual glance at your monitoring app. Compare that to a roof, an HVAC system, or a water heater, all of which will need replacement at least once over the same period.
It is a hedge, not just a purchase
The least appreciated benefit. Electricity rates in this region are structurally rising: data center demand, power plant retirements, grid congestion. Nobody can tell you what PECO or PSE&G will charge in 2032. Solar removes that question from your household budget. The value of certainty is hard to put on a spec sheet, but anyone who has watched their bill climb 20 percent in a year understands it.
The Cons of Solar Panels
These are real. An installer who pretends otherwise is not someone you should trust with your roof.
Buying a system is a significant upfront commitment
Without the federal residential tax credit, a purchased system costs what it costs, and the payback period is longer than it was in 2025. Financing spreads the commitment but adds interest. The honest framing: a purchased system is a long-term investment with a long-term return, and it suits homeowners who plan to stay put. If you might move in three years, buying is a harder case to make, though leases and transfer options exist.
What we will not do here is quote you a price, because any number we put in a blog post would be wrong for your house. System cost depends on your usage, your roof complexity, your equipment choices, and your financing path. That is what a real quote is for.
Your roof has to cooperate
Solar works best on a roof with good sun exposure and at least 10 to 15 years of remaining life. A north-facing roof produces meaningfully less. Heavy shading from mature trees can undermine the economics no matter how good the panels are. And if your roof needs replacement soon, that has to happen first, or you will pay to remove and reinstall the panels later.
None of these are dealbreakers by default. East and west roofs still produce 80 to 90 percent of a south-facing roof’s output. Shading can sometimes be addressed. Roof and solar can be bundled into one project. But these are real constraints, and a meaningful share of the homes we assess turn out to be weak candidates for one of these reasons.
Before moving forward with a solar installation, learn the key factors that determine whether your roof is ready for solar.
Winter production drops, and that surprises people
Solar output in December and January is meaningfully lower than in June and July. Shorter days, lower sun angles, occasional snow cover. The system is sized around annual production, and net metering credits earned in summer offset winter consumption, so the yearly math works. But if you expect July production in January, you will be disappointed. Set expectations on a 12-month horizon, not a monthly one.
The lights go out when the grid goes out, unless you plan for it
A standard grid-tied system shuts down during a power outage. This is a federal safety requirement that protects utility line workers, not a product defect. If backup power during outages matters to you, that requires battery storage, which is an additional decision with its own cost-benefit math.

The industry has some bad actors
This deserves its own entry. Door-knocking sales crews, inflated savings projections, vanishing installers, and lease contracts with aggressive escalators have burned real homeowners. The technology is sound. The industry’s worst sales practices are not. The defense is choosing an installer with in-house crews, a local track record, and projections built from your actual usage data rather than best-case fantasy numbers.
Who Solar Makes Sense For
The strongest candidates share a profile: monthly electricity usage that is average or above, a roof with decent sun exposure and remaining life, a plan to stay in the home for at least the medium term, and a utility territory with high or rising rates. In our region, that last condition is nearly universal now.
The weakest candidates: heavily shaded lots, north-facing-only roof planes, very low electricity consumption, or an imminent move with no interest in transferring a system to a buyer.
Most homes fall somewhere in between, which is why the honest answer to “should I get solar?” is “let someone measure your specific situation.” Anyone who answers that question without seeing your roof and your usage history is guessing.
The Verdict
The pros outweigh the cons for most homeowners in Pennsylvania, New Jersey, and Delaware, and the margin has widened as electricity rates have climbed. But “most” is not “all,” and the difference comes down to facts about your specific home that a blog post cannot see.
If your roof is reasonable, your usage is meaningful, and you plan to be in the home for a while, solar is one of the few home investments that pays you back on a schedule. If your situation has one of the weak spots above, a good installer will tell you that too. Ours will.

Pros and Cons FAQs
What are the main disadvantages of solar panels?
The main disadvantages are the upfront investment for purchased systems, dependence on roof condition and orientation, reduced production in shade and during winter months, and the fact that standard grid-tied systems shut off during power outages unless paired with battery storage. Homes with heavily shaded roofs, north-facing roofs, or roofs needing replacement within a few years are weaker candidates.
What are the biggest benefits of solar panels?
The biggest benefits are lower monthly electricity costs, protection from utility rate increases, additional income from state incentive programs like SRECs, increased home value, and reduced dependence on the grid. In high-rate territories like New Jersey and southeastern Pennsylvania, the financial benefits are among the strongest in the country.
Do solar panels work on cloudy days?
Yes, but at reduced output. Solar panels generate electricity from daylight, not direct sun, so they continue producing on cloudy days at roughly 10 to 25 percent of rated capacity. Systems are sized around annual production, which accounts for seasonal and weather variation.
Is solar still worth it without the federal tax credit?
For most homeowners in PA, NJ, and DE, yes. The federal residential tax credit expired at the end of 2025, but electricity rates in the region have risen sharply, which increases the value of every kilowatt-hour a solar system produces. State programs like New Jersey’s SREC-II and Pennsylvania’s SREC market remain fully available, and lease or PPA options still capture federal tax benefits indirectly through the system owner.
Which homes are not good candidates for solar?
Homes with heavy, unavoidable shading, roofs that face primarily north, roofs needing replacement that the owner is unwilling to address, and households with very low electricity usage see weaker returns. A professional site assessment is the most reliable way to determine whether a specific home is a strong candidate.
