HARDWARE BUILT
TO LAST.
Every component carries industry-leading warranties. We only sell what we'd put on our own buildings.
SolarShield 450W Pro
High-efficiency monocrystalline panel rated at 450W peak output with industry-leading 23.1% efficiency and a genuine 30-year performance warranty.
VaultPower 15 kWh
LFP battery storage system with 15 kWh usable capacity, 6,000+ cycle life at 80% DOD, and zero thermal runaway risk.
SunTrace AI Monitor
Panel-level AI monitoring that detects anomalies in under 8 minutes and predicts failures before they cost you output.
THE DIFFERENCE IS
IN THE DETAILS.
30-Year Performance Guarantee
Every SolarShield panel is warranted at 84.8% of nameplate output at year 30 — a real guarantee, not a pro-rated one.
Storm-Rated Hardware
Mounting systems independently tested to 130 mph winds and 1-inch hail. Coastal salt-air rated as standard on every job.
AI-Backed Monitoring
Panel-level monitoring with ML anomaly detection. Underperformers flagged in under 8 minutes — before they cost you output.
NABCEP-Certified Installers
Every installation is led by a NABCEP-certified PV professional. No subcontractors. No shortcuts.
FROM ASSESSMENT
TO FULL POWER.
Site Assessment
We visit your property, analyze roof condition, shading, orientation, and load data. Full report delivered within 48 hours at no charge.
Custom Engineering
Our engineering team designs a system sized to your actual usage — not a rule-of-thumb estimate. Every design is stamped by a licensed PE.
Professional Install
NABCEP-certified crew installs in 1–2 days for most residential systems. Permits, utility interconnect, and inspections — we handle all of it.
Lifetime Monitoring
SunTrace AI monitors every panel every 90 seconds. Our team responds to anomalies before you notice anything is wrong.
CUSTOMERS WHO KNOW
THE DIFFERENCE.
"After three quotes, S3 was the only company that gave us actual engineering drawings before we signed anything. Installation was flawless and output has beaten projections every single month."
"We put SunTrace on our 240 kW commercial array last year. It flagged a microinverter failure within 6 minutes — before we knew anything was wrong. That system pays for itself every quarter."
