Solar Savings Estimator
Enter your details below for a rough estimate. Real quotes use your actual consumption — but this tells you whether solar is worth exploring.
"Our first installer vanished after a botched install. VoltEdge came in, diagnosed the faults no one else would touch, and got our 5kW system running properly within a week. Best decision we made — R4,200/month savings in year one."
Sandra Nkosi
"Installation took one day. The team was punctual, explained everything, and left the site clean. First full month we cut R2,800 off our Eskom bill. Rounded system recommendation from the savings calculator matched our actual usage exactly."
Pieter van der Berg
"Had an inverter failure that three other companies quoted to replace — at double our install price. VoltEdge repaired the existing unit for R4,800 and got us back online in two days. That's the kind of honesty you don't find in this industry."

What we do
Most installers disappear after the sale. We're built to stay. Comprehensive solar services for homeowners and small businesses across Gauteng.
Complete solar + battery system installs for homes and small businesses. Hybrid inverters, lithium batteries, Tier-1 panels. Certificate of Compliance included.
From R12,000 per install
Scheduled check-ups: panel cleaning, inverter diagnostics, battery health, wiring inspections. Keep your system performing at peak — avoid the 15-30% efficiency loss from neglect.
From R800 per visit
Faulty inverter? Battery not charging? System down? We diagnose fast, quote clearly, and fix it. No runaround — just a qualified electrician who shows up.
Call-out + diagnosis from R500
Add battery capacity, upgrade inverter size, expand panel array. We assess what you have and recommend what's worth doing — not just what's profitable for us.
From R5,000 per upgrade
How it works
WhatsApp or call. We assess your roof, current system (if any), and energy needs. Free site assessment for new installs.
Fixed price, no surprises. We quote on the job, not on what we can upsell. You know exactly what's included before we start.
Installation, repair, or maintenance — done properly by a qualified electrician. All work backed by a Certificate of Compliance.
Sign up for a maintenance plan and we check your system quarterly. Catch issues before they cost you. That's the difference.

That's the gap. A solar system is a 25-year investment. Most people install it and hope for the best. When something goes wrong — inverter fault, battery degradation, panel soiling — they're stuck. VoltEdge exists to make sure that doesn't happen to you.
