PANELS
Three panels.
Every roof covered.
All three are black-on-black monocrystalline, rated for 220 km/h wind, and covered by the same 25-year production warranty. The difference is watts per square meter.

PROCESS
Sunlight to socket,
in four steps.
- 1
Sun hits silicon
Photons knock electrons loose in each cell. That's the whole trick — no moving parts, nothing to wear out.
- 2
Panels make DC
Your array produces direct current all day, even under cloud. Each panel reports its own output.
- 3
Inverter makes AC
A wall-mounted inverter converts DC to the alternating current your home runs on.
- 4
Home first, grid second
Your house uses the power first. Surplus feeds back for credit where your municipality allows it.
HOMEOWNERS
12,400 roofs in.
"July bill was R190. It used to be R4,100. The install took one day and they patched every tile."
"The monitoring app caught a chewed cable in week two. They fixed it before I even noticed."
"Break-even in year four, and the quote matched the final invoice to the rand."
FAQ
Fair questions.
How do I place an order?
Fill in the form below — or WhatsApp us on 072 687 7864 — and we'll email you an invoice for your system. Your order is placed once you reply to that invoice; we respond with a confirmation email and your install date.
Do you do installations?
Yes — panels, inverters, batteries, and the wiring in between are installed by our own team, not subcontractors. We also supply and install diesel generators for full backup power. For an installation quote, email ismaild786@gmail.com with your address and monthly bill, and we'll price the full job.
What happens on cloudy days?
Panels produce 10–25% of rated output under cloud. Your system is sized on your area's yearly average — cloudy days are already in the math, and grid credits from sunny days cover the gap.
Will it damage my roof?
Mounts anchor to rafters with flashed, sealed penetrations — the same method roofers use for vents. We warranty the roof penetrations for the life of the system.
What does the 25-year warranty actually cover?
Production: panels are guaranteed to produce at least 87% of rated output in year 25, or we replace them. Hardware: panels, inverter, and mounting, parts and labor. No fine print about "registration windows."
Do I need a battery?
For load shedding, yes — panels alone switch off with the grid. We size a battery to carry your essentials through a stage-6 slot, and price it in your quote so you can decide with numbers, not vibes.
How long from quote to switch-on?
Typically 3–6 weeks: one week of design, two to four for SSEG registration with your municipality, one install day, then CoC sign-off. We handle every form.
