I Stand Behind Every System I Install — And I Service Systems Other Companies Put Up

I'm Dave Simmer, and I've designed and installed over 1,800 solar systems across Massachusetts since 2011. When I put a system on your roof, I expect it to perform for decades. If something goes wrong, I'm the one who answers the phone and gets it fixed.

But I also know the reality of the solar industry: a lot of national companies have come and gone, leaving South Shore homeowners with systems that aren't producing and no one to call. Whether I installed your panels or someone else did, I can diagnose the problem and get your system back online.

Why Proper Maintenance Matters in Massachusetts

• Lost production means lost money. If your system is down, you're buying expensive electricity from National Grid or Eversource instead of generating your own. You're also missing out on your true 1:1 net metering credits.
• SMART program payments pause. If your system isn't reporting to the utility, your monthly SMART incentive checks stop. Getting it fixed quickly protects that income.
• Small issues become big problems. A loose connection or a failing inverter is easy to fix if caught early. Ignored, it can lead to larger system failures or safety hazards.

What I Actually Do

I provide honest, hands-on diagnostics and repairs. If you're seeing underperformance, error codes on your app, or physical damage from a storm, I'll figure out exactly what's wrong.

A full maintenance visit includes a complete system inspection, a detailed inverter check, a review of all physical and electrical connections, and a production analysis. I specialize in taking on "orphaned" systems—where the original installer disappeared—and bringing them back to life. You can read more about what happens after you go solar to understand normal operation vs. a real problem.

Honest Costs and Numbers

I charge a straightforward diagnostic fee to come out, inspect the system, and pinpoint the issue. Once I know what's wrong, I'll give you a clear quote for the actual repair work. No hidden fees, no open-ended hourly billing. And if the repair isn't worth it—say, replacing a 15-year-old string inverter that's about to fail again—I'll tell you that straight up and discuss replacement options.

Is This Right For You?

If your solar app shows everything is green and your electric bill looks normal, you probably don't need me. Solar panels generally require very little maintenance.

But if your production has dropped, you're seeing red error lights, or your original installer won't return your calls, we should talk. If it's a simple fix you can handle yourself, like reconnecting your gateway to Wi-Fi, I'll tell you that too. I'm not here to charge you for something you don't need.
