Common questions

6 answered
What warranty does the S-Energy SL65-72TDP come with and what does it cover?
The SL65-72TDP series includes a 12-year product warranty covering material and workmanship defects, plus a 30-year linear power warranty. The panel is guaranteed to retain at least 99% of its rated output in the first year, degrading to no less than 87.4% of nameplate power after 30 years. A 30-year power guarantee is a critical input for LCOE calculations on utility-scale solar projects.
Is the S-Energy SL65-72TDP bifacial and what energy gain can I expect?
Yes, the SL65-72TDP is a bifacial module – it generates power from both the front and rear glass surfaces. Under favorable conditions (light-colored ground surface, albedo above 20%), the rear side can contribute an additional 5–15% of energy on top of the rated 575 W front-side output. This bifacial gain is most pronounced in ground-mounted installations over grassy or gravel-covered terrain, which is common on Polish solar farms.
What is TOPCon technology in the S-Energy SL65-72TDP and is it worth the premium?
TOPCon (Tunnel Oxide Passivated Contact) is a next-generation cell architecture and a significant step up from PERC. The additional tunnel oxide passivation layer boosts cell efficiency to around 22–23%, lowers the temperature coefficient to approximately -0.30%/°C, and slows long-term degradation. In practice this means more kilowatt-hours per square meter and better summer performance when modules run hot.
Does the S-Energy SL65-72TDP perform well in a cold climate with heavy snow loads?
The SL65-72TDP is engineered for demanding weather conditions. Its frame and tempered glass are rated for high mechanical loads from snow pressure and wind, which is especially relevant for open-field installations exposed to strong gusts. The low temperature coefficient inherent to TOPCon cells also means the module generates power more efficiently on cold sunny days, making it a solid choice for climates with harsh winters.
Are S-Energy SL65-72TDP panels better suited for utility-scale farms or residential rooftops?
The 72-cell format and 575 W nameplate power make the SL65-72TDP best suited for utility-scale and industrial ground-mount installations. Larger modules reduce the number of electrical connections, lower BoS costs, and shorten installation time on large arrays. For residential rooftops, the module's physical size and weight make handling difficult; smaller 60- or 54-cell formats are a better fit for typical pitched-roof structures.
Is the S-Energy SL65-72TDP resistant to PID and why does it matter for long-term performance?
Yes, the SL65-72TDP series features full PID (Potential Induced Degradation) resistance. PID occurs when high system voltages cause leakage currents that permanently degrade cell performance — a significant risk in the long string configurations typical of utility-scale plants. Full PID resistance ensures stable electrical output over the entire operational lifetime and is a standard bankability requirement for project financing in the renewable energy sector.
