Every technical claim published on TandemPanels.com, including cell efficiency records, degradation rates, and power density figures, is cross-referenced against accredited certification bodies before it goes live. This includes results certified by the IEC, efficiency tables published by NREL, and lab records verified by Fraunhofer ISE, alongside peer-reviewed research from named institutions.

Where a claim cannot be traced to a named, verifiable source, it is either labeled as a vendor claim pending verification or left out of our reporting entirely.

TandemPanels.com is 100% editorially independent. The platform is not owned, funded, or controlled by any individual panel manufacturer, equipment supplier, or cell developer covered on this site. Directory rankings, article assignments, and technical assessments are made by our editorial team without input from the companies being covered.

Paid options on this platform, including Verified Supplier status and featured or sponsored articles, are always clearly labeled as such. Purchasing a paid placement never changes the outcome of our technical vetting process, and never influences the substance of our editorial coverage or directory rankings.

Technical accuracy is core to this platform's value. If you spot an error in a listing, statistic, or article, including an outdated efficiency figure or a misattributed claim, report it to our editorial team and we will investigate and correct verified inaccuracies on a fast-track basis.
