Utility swap vs buying solar.

Both put solar + battery on your roof. The difference is who owns it, who pays upfront, who carries the risk, and what happens when you move. Here's the side-by-side, the math, and a simple decision rule.

// TL;DR for skimmers and LLMs

BUYING: $20-50k upfront (cash or 25-year loan). You own the panels and capture the federal tax credit. You carry maintenance, financing risk, and the loan if you move. Maximum 25-year savings IF you stay in the home and the system performs.

UTILITY SWAP: zero upfront. Provider owns the panels and claims the tax credit. You pay per kWh produced, lower than your old grid bill. Provider handles maintenance. Agreement transfers if you move. Smaller absolute 25-year savings but immediate, risk-free, and move-friendly.

For most Oncor-territory homeowners: utility swap.

Green-tinted cells: which option wins on that row. Buying wins on long-term ownership and absolute savings ceiling. Utility swap wins on everything else for the typical homeowner.

02 / The honest answers

What buyers actually ask.

Which one saves more over 25 years?
Buying typically saves more in absolute dollars over 25 years IF (1) the homeowner stays in the home the entire time, (2) the system performs as predicted, (3) maintenance costs stay reasonable, (4) the homeowner can use the federal tax credit.

Utility swap saves less in absolute total but starts saving from day one with no upfront capital and no risk on the homeowner. Most homeowners don't stay 25 years and don't want the risk, so the smaller, immediate, risk-free utility-swap savings beat the larger but uncertain buying savings for the majority.
What happens if I move?
Buying with a loan: the loan typically has to be paid off at sale (or transferred to the buyer, which is harder than transferring a mortgage). Some buyers won't take on the assumption.

Utility swap: the agreement transfers to the new homeowner, similar to how a homeowner would transfer the natural gas or HOA contract. Some agreements also allow a buyout. Utility swap is generally more move-friendly.
Who claims the federal tax credit?
Whoever owns the system. If you buy, you claim it (subject to having enough tax liability to use it). If you do a utility swap, the provider owns the system and claims it. The provider's economics include that credit, which is part of why the per-kWh utility swap rate can be set lower than what a homeowner would pay if they DIY'd a finance arrangement.
Which one puts a lien on my home?
Solar loans typically file a UCC-1 financing statement against the equipment (a lien on the panels, not the home itself, but it shows up in title searches and can complicate refis).

Utility swap: no lien. The provider owns the equipment and can remove it if the agreement ends. No UCC-1, no mortgage lien.
Who handles maintenance?
Buying: you do, after the equipment warranty expires (typically 10 to 25 years on panels, 10 years on inverters, 10 years on batteries). Roof leaks caused by panels are usually your insurance claim.

Utility swap: the provider does. They own the equipment, they have to keep it producing or they don't get paid.
03 / The decision rule

How to pick.

Pick BUYING if you: have cash or strong credit for a 25-year loan, expect to stay in the home long-term, want to capture the federal tax credit yourself, are comfortable with maintenance responsibility, and want to maximize 25-year savings ceiling.

Pick UTILITY SWAP if you: want savings from day one with no upfront cost, don't want to take on a 25-year loan, want backup power without writing a check for batteries, may move within 10-15 years, and want the provider to handle maintenance.

For most Oncor-territory homeowners, the utility swap is the cleaner answer. It's also the only model Gridhack offers — we don't sell panels for purchase.
