SHARING SUNSystem Upgrades
Solar that no longer covers the bill? Let's fix that.
Homes change — EVs, hot tubs, a finished basement, a growing family. A system sized for your 2015 bill can fall behind your 2026 one. We upgrade existing solar the right way: panel additions, inverter replacements, and battery storage, engineered to work with what's already on your roof.
What we upgrade
Three upgrades, one crew
Most upgrade projects combine two of these — and bundling them is usually the smartest money, because the permit, engineering, and utility paperwork happen once instead of twice.
Add panels to your existing system
When your array no longer offsets the full bill, we add capacity the right way — new panels on their own dedicated equipment, engineered to coexist with your original system without touching its warranty or performance. We handle the utility interconnection amendment, the permit, and the electrical engineering, including checking whether your main panel can take the added capacity.
Inverter & microinverter replacement
String inverters typically last 10–15 years — often half the life of the panels above them. Whether yours has failed, is throwing error codes, or is simply nearing end of life, we replace string inverters, convert systems to microinverters, and bring older systems up to current code while we're at it. If you're also adding panels, this is the moment to do both.
Battery storage retrofit
Add backup power and store your daytime production for evening use. We retrofit battery storage to existing solar systems — sizing the battery to what your array actually produces and what you actually need to keep running when the grid doesn't.
Critter guard & squirrel damage repair
Nesting animals under an array chew wiring and pile debris against your roof. We install critter guard on existing systems and repair the damage they leave behind — often discovered during an upgrade assessment.
Straight talk
When is an upgrade worth it?
Honest answer: a two-panel addition by itself rarely makes financial sense, because the permit, utility application, and engineering cost the same whether you add two panels or ten. Upgrades pencil out when they're bundled — panels plus a battery, or panels plus an inverter that was due for replacement anyway. That's exactly what we'll tell you in the assessment: what's worth doing, what isn't, and what to wait on. No pressure, no padding.
How it works
From assessment to switch-on
Assessment
We review your production history, your bill, your existing equipment, and your roof — then tell you what upgrade actually solves the problem.
Design & paperwork
We engineer the addition, pull the permit, and file the utility interconnection application. You sign — we handle the rest.
Installation
Our NABCEP-certified crew installs the upgrade, typically in a single day for most residential projects.
Inspection & switch-on
We walk the inspection, secure permission to operate from the utility, and confirm the system is producing before we call it done.
