Engineered for your actual usage, installed by licensed electricians, and inspected without corrections.
We design solar around your real utility data — not a one-size template. System sizing, panel placement, and inverter selection are engineered for your roof, your shading, and your goals.
Because we are electrical contractors first, the parts of solar most installers subcontract — the panel work, the interconnection, the load calculations — are done in-house, to our standard.
Custom system design from your actual usage history
Tier-one panels with microinverter or string options
Tile, shingle & foam roof mounting done without damage
All permitting & utility interconnection handled
Monitoring set up and explained before we leave

Every kilowatt-hour you produce is one you stop renting from the utility at rates that rise almost every year. A right-sized system typically offsets the majority of your bill from day one — and the math only improves as rates climb.
Use the calculators on our homepage for a ballpark, then let us run your real numbers from your actual bills. Estimates are free, and nobody at GreenTag is paid to oversell your system size.
Tell us about your project — a licensed professional will follow up with clear next steps.
