Let’s Be Straight About Why There Is No Number at the Top of This Page
You searched for a price, and most of the pages competing for your click will hand you one: a national average, a per-watt figure, a tidy range with a dollar sign. Here is what those pages will not tell you: the average is built from thousands of homes that are not yours, and your actual quote can land far from it for reasons that have nothing to do with anyone overcharging you.
A solar system is closer to a kitchen renovation than a refrigerator. There is no MSRP. The price is assembled from your electricity usage, your roof, your electrical panel, your equipment choices, and how you pay. We are not going to print a number that pretends otherwise. What we will do is show you exactly what builds the number, where quotes hide costs, and how to tell a fair price from an inflated one, which is more useful than any average and exactly what you need before you talk to any installer, including us.
And if you’re still weighing whether solar makes sense at all, our honest pros and cons of solar panels covers the tradeoffs the same way.
The Five Variables That Build Your Price
1. How much electricity you use
System size follows usage, and price follows size. The starting input for every legitimate quote is your last 12 months of utility bills, because a household using 14,000 kWh a year needs a substantially larger system than one using 8,000, and the materials and labor scale with it.
This is also why your neighbor’s price tells you almost nothing about yours. Same street, same builder, different lives: one house runs a heat pump and charges an EV, the other heats with gas and is empty all day. Different systems, different prices, both correct.
2. What your roof demands
Labor is a major share of any installation, and your roof sets the labor. A single broad south-facing plane on a one-story ranch installs quickly. A steep, cut-up roof with dormers, multiple planes, and three stories of ladder work takes longer and costs more per panel. Roofing material matters too: standard asphalt shingle is the baseline, while slate, tile, and certain metals require specialized mounting and handling.
And roof condition sits underneath all of it. Panels last 25 years or more. If the roof beneath them has 5 years left, the responsible move is addressing the roof first, and that belongs in the project conversation from day one, not as a surprise after signing.
3. The equipment tier
Panels, inverters, and racking come in good, better, and best, like most things. Higher-efficiency panels cost more per panel and earn it back on tight roofs where space is the constraint. Premium inverter architectures cost more and matter most on partially shaded roofs. On a big, open, unshaded roof, mid-tier equipment is often the rational choice, and a quote loaded with premium gear a simple roof does not need is one of the patterns to watch for.
4. Your home’s electrical readiness
Solar ties into your main electrical panel, and the panel has to be able to accept it. Most homes built or updated in recent decades are ready. Some older homes need a panel upgrade first, which is real money and a real line item. A quote that does not mention your panel either confirmed it is fine or did not look. Ask which.
5. How you pay
The same physical system carries a different total cost depending on the financing path. Cash is the lowest lifetime cost. Loans add interest, and some solar loans carry dealer fees baked into the system price rather than disclosed as financing cost, a practice worth interrogating in any quote. Leases and PPAs remove upfront cost entirely and shift the equation to a monthly payment, with the provider claiming the commercial tax credit and pricing accordingly.
There is no universally right answer. There is a right answer for your cash position, your tax situation, and your timeline, and a real quote shows you the same system priced through each path
What Changed About Cost in 2026
One change matters above all: the federal residential tax credit (Section 25D) expired December 31, 2025. For a homeowner buying a system, there is no longer a 30 percent federal credit to subtract. That raised the net cost of purchased systems compared to 2025, full stop, and any installer still implying a federal credit on a purchase is misleading you.
Two counterweights keep the math working. Electricity rates across PA, NJ, and DE rose sharply over the same period, around 20 cents per kWh in PECO and Delmarva territory and roughly 26 cents at PSE&G, which raises the value of every kilowatt-hour a system produces. And the state incentive layers survived intact: New Jersey’s SREC-II payments, property and sales tax exemptions, Pennsylvania’s SREC market, Delaware’s utility rebates.Leases and PPAs additionally still route the commercial Section 48E credit to homeowners indirectly through lower payments.
Cost went up. Value went up. Which effect wins depends on your utility, your usage, and your roof, which is the recurring theme of this page.
The Hidden Costs, Named
The phrase “hidden costs of solar” gets searched constantly because the industry earned it. Here is the actual list, in the open.
Electrical panel upgrades. Covered above. Common in homes with older 100-amp service. A legitimate assessment checks this before quoting.
Roof work. If the roof needs repair or replacement, that cost is part of the real project total whether or not it appears on the solar quote. Bundling roof and solar into one project is often cheaper than sequencing them separately, but either way the number belongs on the table.
Trenching and distance. Ground-mounted systems and panels on detached structures require trenching conduit back to the house. Distance is cost.
Dealer fees inside financing. The big one. Some solar loan products embed a substantial fee in the quoted system price in exchange for a lower advertised interest rate. The system did not get more expensive to build; the financing did. Ask every installer, directly: “Does this price include a dealer fee, and what is the cash price for the identical system?” The answer, and the willingness to answer, tells you who you are dealing with.
Permit and interconnection costs. Modest, but real, and they should appear on the quote rather than materialize later.
None of these are scandalous when disclosed. All of them are scandalous when discovered after signing.
How to Actually Get Your Number
The path from “researching” to “knowing” takes one step: a quote built from your data. A real one requires your last 12 months of usage and a look at your roof, and it should come back to you itemized: sizing basis shown, equipment named, roof and electrical findings stated, every financing path priced side by side, dealer fees disclosed or absent, production estimate with assumptions visible.
Get two or three of these and compare them on the line items, not the bottom line. The cheapest number with vague line items is routinely the most expensive project by completion. The clearly itemized quote from the installer with in-house crews and a local track record is what a fair price looks like in practice.
That is also, not coincidentally, what a Sunwise quote looks like.
Get the Number That Is Actually Yours
A Sunwise consultation produces the thing this page cannot: your price, built from your bills and your roof, itemized to the line, with every payment path shown side by side and zero pressure attached. It costs nothing and it ends the guessing.
Solar Cost FAQs
Why do solar costs vary so much between homes?
No two homes need the same system. Your price is built from five inputs: how much electricity you use (which sets system size), what your roof demands in labor and mounting (pitch, planes, material, stories), the equipment tier your situation actually calls for, whether your electrical panel needs upgrading, and how you pay. Two identical houses on the same street can carry very different and equally fair prices because the families inside use energy differently. That’s why a quote built from your 12 months of usage data and your actual roof is the only number that means anything.
Are the average solar prices I see online accurate?
They are accurate as national or state averages and unreliable as predictions for any individual home. Averages blend small and large systems, simple and complex roofs, and different equipment tiers across thousands of installations. Your actual price can sit well above or below a published average for completely legitimate reasons, which is why installers quote from your usage data and roof rather than from a table.
What are the hidden costs of solar panels?
The most common surprise costs are electrical panel upgrades for older homes, roof repairs or replacement before installation, trenching for ground mounts or detached garages, and dealer fees buried inside some financing products. A legitimate quote surfaces all of these upfront. The presence of unexplained vagueness around any of them is a red flag.
How much does solar cost after the tax credit in 2026?
The federal residential tax credit (Section 25D) expired December 31, 2025, so there is no federal credit to subtract from a homeowner-purchased system in 2026. However, lease and PPA providers still claim the commercial Section 48E credit and pass the benefit through as lower monthly payments, and state incentives in PA, NJ, and DE continue to reduce effective cost.
How do I know if a solar quote is fair?
A fair quote is itemized and built from your actual data. It should show your 12-month usage as the sizing basis, name the specific equipment, break out any roof or electrical work, disclose all financing fees including dealer fees, and state the production estimate with the assumptions behind it. Comparing two or three quotes on these elements, rather than the bottom-line number alone, reveals which is genuinely fair.
