If you've researched home solar, you've probably pictured panels on the roof selling power back to the utility for credits. That's one kind of solar — but it's not the only kind, and it's not the kind that pairs with the home batteries we focus on. Here's the honest breakdown of the two, and why we work in the simpler lane.
Two very different kinds of home solar
Grid-tied solar (the "traditional" kind): panels feed a grid-tie inverter that pushes power onto the grid. When you make more than you use, you bank credits through a net-metering program (like Dominion's Solar Choice). It can lower your bill nicely — but it's a bigger project: a permitted, professionally installed system, a separate grid-tie inverter, and an interconnection agreement with utility approval before you can switch it on. And here's the part most people don't know: grid-tied solar without a battery shuts off during an outage — anti-islanding rules cut it off to protect lineworkers, so the one time you'd want your panels most, they're dark.
Battery-coupled solar (what we do): panels wire straight into your home battery's solar input. The battery stores the energy and your house uses it. Nothing gets exported to the grid, so there's no interconnection, no net-metering enrollment, and no utility sign-off. It keeps producing in an outage, you can add it in stages, and it bolts onto the battery system you're already considering instead of being a separate build.
Why we focus on battery-coupled
It comes down to the same things the whole site is about — resilience and simplicity:
- It works when the grid doesn't. Solar + battery keeps your home running through an outage. That's the entire point of having a battery, and grid-tied solar alone can't do it.
- No interconnection headache. Because nothing is exported, you skip the agreements, approvals, and waiting that grid-tied solar requires.
- You can grow it in stages. Start with a small array and add more over time as budget allows — no need to size the whole thing up front.
- It pairs with the battery. The panels feed the same system, charging the battery by day so you run on your own power into the evening.
The honest tradeoff
I'm not going to pretend battery-coupled is always the cheapest path, because it isn't. If your only goal is maximum bill savings, grid-tied solar with net metering can come out ahead — you get credited for every excess kilowatt-hour you send back. Battery-coupled solar doesn't export, so you can't bank surplus; you size it to power your own home, not to sell.
What you're buying with battery-coupled solar is independence and resilience, plus a far simpler install that doesn't depend on the utility. If you want to wring out every last net-metering credit and don't care about outage power, grid-tied is a legitimate (separate) project — just know it won't tie into these battery systems. If you want power in a storm, energy you control, and something you can add to a battery in stages, battery-coupled is the lane we work in.
How the savings actually work (battery-coupled)
Because you don't export, your solar savings come from using your own production instead of buying it — directly during the day, and from the battery in the evening. The honest math: you save the rate you'd otherwise pay on the energy your panels offset, capped by how much you actually use. On a time-of-use plan, solar charges the battery during the day so you lean on the grid even less. It's a real, additive saving on top of the battery's rate-shift savings — but a modest, usage-bound one, not a "sell power and get rich" story.
How much solar your system can actually take is its own question — and it's set by two ceilings, the battery's input rating and your own usage. I break that down in how much solar a home battery can actually use.
My own plan
I'm adding solar in stages, the same way I'd tell anyone to: start small and grow into it. First a ground-mount array to learn the real-world output, then panels on the main house roof down the line. No rush to max it out — the battery delivers most of the value on its own, and solar stacks on top when the time's right.
When you're ready to see what solar adds for your house, the analyzer folds it in as an optional layer — a rough, honest estimate on top of your battery numbers, sized to your real usage.
