Tindo unveils Australian-made 410 W solar panel with 20.6% efficiency

Australian module manufacturer Tindo Solar has unveiled a new solar panel based on M10 wafers for residential and business rooftop systems. The new addition to the company’s Karra range has a rated power of 410 W at 20.6% module efficiency and 23.1% cell efficiency.

Tindo Solar, Australia’s only solar panel manufacturer, has released its largest residential rooftop module yet, announcing that its 410 W Karra panel has now been certified for sale and STC rebates.

The 410 W Karra panel is made with 108 half-cut monocrystalline cells based on M10 wafers with a size of 182mm[2]. It operates with a maximum system voltage of 1,500 V and a temperature coefficient of -0.34% per degree Celsius.

The new panel measures 1,731mm x 1,149mm x 40mm and weighs 21.5kg. It is built with fully tempered glass and is wrapped in a black anodised aluminium alloy frame. It comes with a 25-year product guarantee and a 25-year performance guarantee. End power output is guaranteed to be no less than 80% of the nominal output power.

Tindo chief executive officer Shayne Jaenisch said the 410 W Karra panel had been designed specifically to cater for an increasingly sophisticated rooftop solar market.

“Five years ago, Australians wanted solar power on their roofs, and the rebates and feed-in tariffs were designed to drive installations,” he said. “Now, the market is more focused on solar PV with battery, VPPs (virtual power plants), and a power supply with the most efficient and reliable output.”

Tindo said the first order for the panels, which are being manufactured at the company’s headquarters[3] at Mawson Lakes in Adelaide, was from a large corporate buyer which is installing 200 kW systems on its property assets.

Jaenisch said the 410 W panel had been tested by TUV SUD Korea with engineers from the certification body confirming it produced power at about 21% module efficiency and 23.1% cell efficiency and recorded just 0.07% cell-to-module (CTM) loss ratio. Tindo said the industry average energy efficiency of a solar module is between 17 and 19%, and the average CTM loss is 2-3%.

“We should be proud that in Australia we have the engineers and the technical skills to commercially produce one of the highest-performing solar panels in the world, right here in Adelaide,” Jaenisch said.

“If Australia is going to lead the world in the energy transition, we have to develop a sovereign capability in renewables.”

Jaenisch said the company had looked to address growing demand for ethically and sustainably produced modules with the new panel coming with an end-of-life recycling guarantee.

“Australians are serious about recycling and forced labour,” he said. “We use a global assurance firm to audit our supply chains for issues such as forced labour, and we have a recycling guarantee so that decommissioned panels are recycled for industrial re-use by Reclaim PV[4].”
