The great news is that solar panels have seen substantial technical advancements and become significantly more efficient. As a result, increasing numbers of panels can be re-used and re-purposed.
Providing a second life to unwanted solar modules is a great way to reduce your carbon footprint. At the Renewable Recycling Company we identify any panels that are still operating at 80% of nameplate capacity. We also test and, where possible, repair defective panels, so that they can be put back into energy production.
Even with a reduced efficiency, there are several options to repurpose a solar panel. This may be for smaller off-gird applications, backup power systems or for secondary markets in developing regions where access to electricity is limited and affordability is essential.
To allow the assets to be repurposed affectively and safely, they first need to be assessed. This will allow complete confidence for when the panel is put back into operation.
The panel is initially visually inspected for damage to the glass and framework, such as chips & cracks.
We check all electrical connections for signs of corrosion & damage. Testing of the bypass diodes and replacement as required.
We measure several voltage & current conditions, comparing them against the nameplate spec of the panel.
Using solar flash testing, we can measure the power output of the panel, in Watts, and can compare this to the panel's rated power output. The panel should produce at least 80% of its nameplate capacity.
Documentation is completed on each panel allowing it to be graded, dependent on the results. These steps ensure that a panel can be safely & effectively put back into operation.
