At the heart of the Karra-250 photovoltaic module is brilliant technical and intelligent design fused with a range of innovative materials that make it the ultimate solar panel.
Everybody should have a panel this advanced.
Karra-250 solar panel is manufactured in Australia and we invite you to visit
our factory to watch panels being created.
You will love the Karra-250, the most beautiful solar panel … in the world.
At Tindo, we want a 25 year warranty to actually mean something. So 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. In addition to the 250W panels installed at Desert Knowledge, Tindo also manufacture a range of other modules in its Mawson Lakes factory.
Our Production Line
operates a state of the art 60MW capacity production line in Adelaide South
Our line is fully automated with a focus on quality control and sophisticated engineering.
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-250. 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.
Commitment to Quality
At Tindo 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 panels. Tindo is Made for Life.
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.
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.
We have numerous visual inspection points to ensure that the Tindo panels are Made for Life.

Notes on the Data
Monitoring Interruption for UPS Battery Replacement
The disconnection and re-connection of the solar arrays and weather station equipment while a new site connection was being established prompted the already flattening UPS batteries which power the site’s energy meters to fail and require immediate replacement. Data recording was affected from approximately 2.30pm ACST, Monday 10 July to 4.00pm, Wednesday 12 July.
Affects weather data for DKASC, Alice Springs
Partial System Outage
One of the major switchboards at the DKASC lost power yesterday 01/12/2016 at ~11:00 am. This isolated and shutdown array sites 23 through to 37 inclusive. The switchboard was re-energised at ~16:30 today (02/12/2016) and is again operating normally. Data for this period for these sites is lost.
