WINAICO / Solar panels
30-year product warrantyWINAICO WBC Ultra Black
A 485 W all-black panel with glass on both sides, using N-type back-contact cells, so there are no metal lines on the front. It carries a 30-year product warranty and a 30-year performance warranty from WINAICO's Sydney-based Australian company.

WHY THIS PANEL
485 W per panel, and what that means on your roof.
What it is made of, what it is guaranteed to do, and the figures that decide how many fit your roof and your inverter.
23.8% module efficiency
The share of the sunlight landing on it that becomes electricity. Higher means more output from the same roof area, which matters most when roof space is tight.
N-type back contact, bifacial glass-glass
N-type cells hold their output better in heat and lose less each year than the older PERC cells. Glass on both sides, and the back of the cell also collects light bounced off the roof.
-0.26 %/C in the heat
Output lost for every degree the cell runs above 25 °C. Closer to zero is better on a Canberra summer roof, when a panel can sit 30 degrees above the air.
0.35% a year after year one
About 1% in the first year, then 0.35% a year: the slow fade every panel has, and what the performance warranty is a promise about.

Electrical figures are at standard test conditions; the full standards list is on the manufacturer datasheet (open it). We check string voltages against your inverter and your roof before quoting.
What does the wattage actually mean?
It is the panel’s output in full test conditions – 1,000 watts of sunlight per square metre at 25°C. A 440 W panel makes 440 watts at that moment, not all day. Over a year in Canberra each kilowatt of panels returns roughly 1,400 to 1,500 kilowatt hours, depending on pitch, orientation and shade.
Is a higher wattage always better?
Not on its own. A higher-wattage panel is usually physically bigger, so you may fit fewer of them. What matters is the total kilowatts you can get onto the roof, the efficiency per square metre, and whether the voltage and current suit your inverter.
What is module efficiency?
The share of the sunlight landing on the panel that becomes electricity. Higher efficiency means more output from the same roof area – it matters most when roof space is tight.
Why do Voc and Isc matter?
They set how many panels can be wired in a string and whether that string stays inside your inverter’s safe window. Cold mornings push voltage up, so the design has to allow headroom. We check this for your roof before quoting.
What is degradation?
Panels lose a small amount of output each year. A typical modern panel gives up about 1% in the first year and a fraction of a percent each year after, and the performance warranty is the manufacturer’s promise about where that leaves you decades later.
THE PRODUCT, EXPLAINED
What matters in everyday use.
30-year product warranty issued in Australia
Back-contact cells with an ultra-black finish
Bifacial glass-glass build with a Class A fire rating
88.85% output guaranteed at year 30
Could it suit your home?
Homeowners who want a premium all-black look and the longest product warranty, whose roof can take a slightly larger panel.

BACKED BY US, NOT JUST THE MANUFACTURER
A 10-year workmanship warranty on solar and battery installations.
Manufacturers cover their products. We cover the installation. For 10 years from practical completion, a defect that comes from our workmanship in installing your solar panels, inverter or battery — the mounting, the cabling, the installation work — is put right by us: repaired, re-done, or the affected installation part replaced, at our cost and at our choice of remedy.
- It stays with the home. Sell up, and the new owner gets the remainder, on the same terms.
- Switchboard, EV charger and heat pump installation work carries its own 1-year workmanship warranty from the date of installation.
- It covers our work, not the products. A panel, inverter or battery fault is a manufacturer warranty matter, with its own period.
- What it does not cover: damage from misuse, changes or repairs by someone else, storms, surges and grid events, pests and corrosion, building movement, ordinary wear, and internet or monitoring problems. A call-out where no workmanship fault is found may be charged.
- Keep your rights. It adds to the Australian Consumer Law guarantees, never replaces them.
- To claim: email engineering@solar4life.com.au or call 1300 997 005 with your name, the installation address, what is wrong and photos. Tell us promptly; delay can affect a claim.
Residential installations. The full terms are in your installation agreement.
