At the heart of the Tindo Karra photo-voltaic module is brilliant technical and intelligent design fused with a range of innovative materials that make it the ultimate solar panel.

In addition to the Tindo Karra POLY range we are pleased to welcome our new Tindo Karra-295W PERC monocrystalline which will allow Tindo to fit more power into less space for a comparable price. The development and testing of this module has been in the making for some time now with the participation of the Australian National University in Canberra.

Tindo Karra Panel

Everybody should have a panel this advanced.

The Tindo Karra-270 POLY and 295W PERC MONO solar panels are manufactured in Australia at our Mawson Lakes manufacturing facility. We openly invite industry and prospective clients to book a time to visit our factory to watch our panels being created.

You will love the Tindo Karra, the most beautiful solar panel … in the world.

We have designed and are manufacturing a module without compromise. our partners are global solar industry leaders who zealously value their fine reputations. Tindo Solar is proud to be associated with them.

Our Promise

Tindo Karra solar modules give you a minimum of 25 years of long-term high performance thanks to our premium quality. Tindo’s performance has undisputedly outperformed our competition on durability hence we want “Australian Made” to stand for something!

After 8 years of production, Tindo’s installed module fleet failure rate is some 200 x lower than our competitors, hence why we have increased our product warranty from 10 to 12 years. Our warranty is exceptionally customer-friendly, easy to understand and offer long-term security.

Our Production Line

Tindo operates a state of the art 60MW capacity production line in Adelaide South Australia.
Our line is fully automated with a focus on quality control and sophisticated engineering.

Bridgestone EVA

EVA from Bridgestone has a long history in the solar panel industry providing encapsulation material of the highest quality. Bridgestone’s EVA is optically clear, impervious to water and can be relied on for decades.

Dow Corning Silicone

Silicone edge seal from Dow Corning has been a performer of the highest calibre, proven since panels were first commercialised. Tests show the seal outperforms all competition in cohesiveness and lap shear strength.

DuPont Back Sheet

Tindo uses DuPont Tedlar film-based backsheets in the manufacture of the Karra-275. Back sheets are used as a vapour barrier and to protect sensitive components of the panels. Tedlar is the only film based back sheet that has successfully protected solar panels for more than 25 years.

Enphase Microinverters

SA Product InstallSA Product Supply

We use Enphase micro inverters on our AC solar systems. They are rated up to 85degC, have an IP67 moisture and dust resistance, are fully potted, have integrated earthing built in to them, have reactive power control for future smart grids and they are the world leaders in micro inverter technology. We are using their 5th generation product and with over 7 million units shipped globally, reliability and performance are proven.

Commitment to Quality

At Cool or Cosy we are committed to providing an Australian product that can be benchmarked against any panel in the world. We have taken extensive steps to ensure the quality and reliability of our products. Tindo Solar panels are Made for Life.

Electroluminescence Testing

Visual testing of the surface of solar panels does not provide adequate assurance of the quality of a module.

There are numerous defects in a solar cell for example:
• cracks caused during production or transportation of solar cells,
• fingerprints that were left behind on cells while printing the cell grid,
• micro cracks caused by heat stress while stringing,
• cracks caused by faulty handling in the module production line,
• defect contact point between ribbons and cells

All of these defects can cause substantial reduction of the quality of modules. Though modules may generate adequate output immediately after they have been produced, cracks can at a later point in time (even years later) be the reason for substantial output reductions or loss of production.

Tindo uses an Electroluminescence (EL) Tester on each panel that we produce. This provides a reliable quality control system for solar panels in which all defects are detected so you as the end consumer can be assured of output from your panels well into the future.

Flash Testing

As part of the final step of the production process, each Tindo panel is Flash tested.
During a flash test the panel is exposed to a flash of light from a xenon filled arc lamp. The output spectrum of this lamp is as close to the spectrum of the sun as possible. The output from this flash test is validated to ensure that the solar panel is performing as rated to its specifications.
We will only send the panel out to the consumer if we are satisfied that the panel produces as its nameplate suggest.

Visual Inspection

We have numerous visual inspection points to ensure that the Tindo panels are Made for Life.
These include:
  • Inspection to ensure the there are no air bubbles or blisters in the lamination process
  • Junction box has been sealed correctly to the back of the module.
  • Framing has formed a water tight seal to protect the cells

German Quality – Market Leading Warranty

SA Product InstallSA Product Supply

The South Australian Marshall Government has recently announced a $100 million Home Battery Scheme that will assist households to purchase sonnen storage systems through a combination of direct subsidy and low-interest loans.

sonnen is investing in the South Australian community by building a manufacturing facility in Adelaide.

The sonnenBatterie is a hi-tech solar battery storage system that has proven itself in thousands of households every day, outperforming other batteries in its class. This durable, intelligent energy manager meets high standards of safety and quality.

The Minister for Trade, Tourism and Investment David Ridgway said, “Manufacturing has been a key foundation of South Australia’s economy for decades and this is set to continue on the back of leading companies like sonnen establishing an advanced manufacturing presence in our State.”

The sonnen facility at the former Holden site at Elizabeth will be producing batteries by November 2018 to meet the demand from Australian householders seeking to substantially reduce their power bills. The manufacturing facility will generate hundreds of direct and indirect jobs and provide employment opportunities for many former Holden workers.

The  sonnenBatterie is guaranteed for 10,000 cycles or 10 years – providing you peace of mind that your battery system is built to last. This is the best home energy storage warranty around – considerably more generous than competing products!

Couple this proven performance with Cool or Cosy, which has been installing quality, Australian made solar solutions throughout Australia, and you’ll have the reassurance of extracting the best possible return from your battery investment.

SonnenBatterie Features:

  • 20 year Design Life backed by an industry leading warranty – 10,000 cycles (2.7 cycles per day) or 10 years before battery storage level degradation.
  • Store excess solar power for use at night to help maximise your solar self-consumption.
  • Sonnen Protect provides backup power in events of grid outages.
  • The Sonnen App and online portal allow you to track yourself consumption, battery state of charge as well as turn off and on devices connected to Z-wave Power Adapters.
  • Smart Energy Management software manages your energy intelligently throughout the day.
