There was a window — and I think most people missed it. A few years back, the federal government and New York State were practically paying you to put solar panels on your roof. Between the federal tax credit and the NYSERDA grant, we were looking at roughly $10,000 coming off the top of a $19,668 system. Cost after incentives: $8,271. On a 15-year loan at 6.99%, that’s $75 a month. Our electricity bill at the time was more than that. The math was almost insultingly obvious. You’d be a fool not to do it.
So we did it. And I’d do it again. But it’s a longer story than the brochure suggests.
The Good Part First
New York State Solar Farm — a local company, office near our supermarket, solid reviews — quoted us a 6.44 kW system, 14 panels, estimated annual production of 8,393 kWh. The production chart they showed us projected 123% offset of our utility usage. That’s not a rounding error. That’s genuinely more solar production than we consume, most months of the year.
The panels themselves were SunPower Maxeon 6s. If you’ve done any research on residential solar, you know that name. At the time, they were considered the best panels on the market — up to 22.8% efficiency, a 40-year warranty, less than 0.25% annual degradation. Premium price, premium product. I felt good about the choice.
The Installation Wasn’t Nothing
We decided to put the panels on the barn roof, not the house. Lifetime shingles — though, you know, whose lifetime — and a clean southern exposure. Made sense. What didn’t make sense, at least not immediately, was that we had to reinforce the rafters before the installer could pull the permit.
The original suggestion was a knee wall in the loft. I looked at that plan and said: that’s going to eat up half the loft space for a wall that does nothing but sit there. So instead we sistered the rafters — bolting new 2x10s alongside the existing 4x10s, every rafter on the panel side and every other one on the opposite side. Getting the right lumber in the Hudson Valley involves more phone calls than you’d think. I ended up sourcing green lumber from Ghent Wood Products up in Columbia County — give them a call at 518-828-5684 if you’re ever in the same situation. Green means wet when purchased, slightly oversized to account for shrinkage.
The engineering drawing makes it look clean. The actual afternoon involved a lot of standing in the loft arguing with my friend about whether a board gets longer when you angle it. (It doesn’t get longer. The space it has to travel gets longer. We eventually agreed on this.)
Permit pulled. Panels installed. Done.
The Unforeseen Circumstances
Two of them. Maybe three.
The first: we got an EV around the same time. A Tesla, because we needed a third-row vehicle and the incentives lined up. I had read the forums. I had seen people say things like “our electric bill barely went up.” I believed them. I should not have believed them. That car uses an extraordinary amount of electricity. The 25% extra production buffer we had built in? Gone. Evaporated. Our utility bill is about the same as it was before the solar panels, because the solar panels are now essentially a very expensive car charger. It offsets some household usage. Just not the way I pictured it.
The second: I didn’t get a battery backup. This one still stings. If the power goes out, your solar panels don’t work. I know how that sounds. You’ve got panels on the roof actively generating electricity and your house is dark. That’s how the grid-tied system works — it shuts down during an outage so it doesn’t backfeed power to lines that workers might be on. Without a battery, you’ve got a generator-dependent house with a solar system that sits idle every time a storm rolls through. The cheapest battery backup options are still a significant investment on top of what you’ve already spent. I didn’t price it in. I should have.
The third: SunPower went bankrupt. Filed Chapter 11 in August 2024. Auditors resigned. Financials restated. CEO gone. The company that made the industry’s best panels — the ones backed by a 40-year warranty — is now effectively gone, with assets acquired by Complete Solaria. The panels themselves, now manufactured under the Maxeon brand, are still being made and the warranty technically transfers. But “technically” is doing some work in that sentence. I’m not panicking. The panels are performing. But I’d be lying if I said it doesn’t add an asterisk to the story.
The Part That Actually Makes Me Angry
The incentives that made this decision obvious are being rolled back. The federal tax credit that cut our gross system cost by $5,514, the NYSERDA grant that took off another $1,288 — those programs exist because distributed solar generation is genuinely good policy. People put clean energy on their roofs, reduce grid demand, and the utility company actually pays you when you produce more than you use. Net metering. It works.
And at the exact moment when EVs are putting new load on the grid, when AI data centers are demanding power at a scale the infrastructure wasn’t built for, when every utility company in the Northeast is warning about capacity constraints — we’re pulling back the incentives that would get more solar on more roofs. I don’t have a clean political explanation for why. I just know it’s backwards.
What I’d Tell You
Get the panels. If the incentives are still available in your state, the math is probably still compelling — just run the actual numbers, not the optimistic ones. Size the system for what you expect to need, not what you currently use. If there’s any chance you’re getting an EV in the next five years, size up. Budget for battery backup from the start — it’s much easier to finance it as part of the original project than to retrofit it later. And pick a company that’s been around long enough that you’re not crossing your fingers about their warranty.
The system works. The barn roof is producing electricity right now. I just wish I’d gone bigger.
Even that's Odd
