Tescom Solar TS275-60P POLYCRYSTALLINE photovoltaic panels are a proven solution based on multicrystalline technology, which performs perfectly in Polish solar conditions. The 60-cell design has been optimized for maximum energy stability, which translates into predictable yields even in weaker, diffused light. This series effectively solves the problem of power degradation thanks to the use of advanced protective layers, which guarantees long-term security and a reliable return on investment for investors. The use of high-transmittance tempered glass and a solid, reinforced aluminum frame makes the modules exceptionally resistant to extreme snow loads and gusty winds. It is an ideal proposition for homeowners and farms looking for an optimal quality-to-price ratio and focusing on components with high mechanical durability. They are distinguished from the competition primarily by rigorous quality control and high resistance to weather conditions, which minimizes the risk of micro-cracks in the cell structure. By choosing these modules, you gain a solid base for a PV system that focuses on reliability and real performance in daily operation, not just in laboratory conditions.

Common questions

6 answered
Is the Tescom Solar TS275-60P POLİKRİSTAL series still available for purchase?
The TS275-60P POLİKRİSTAL series has been discontinued from Tescom Solar's current production. The model is now available only through distributor stock or as remaining units from the last production batches, while supplies last. Customers looking for new modules from this Turkish manufacturer should ask their supplier about current equivalents, such as monocrystalline PERC or bifacial panels that have replaced the older polycrystalline lines.
How does the polycrystalline technology in the TS275-60P differ from monocrystalline panels?
Polycrystalline cells in the TS275-60P are made from multiple silicon crystals, which lowers production cost but results in somewhat lower efficiency than monocrystalline PERC panels. At the same 275 Wp power rating, the module therefore takes up more roof area. The advantage is more predictable performance under diffuse, weaker light, common on cloudy days in the Polish climate, as highlighted by the manufacturer's description of the series.
What warranty applied to the Tescom Solar TS275-60P panels?
The manufacturer typically offered a 10-12 year product warranty on this series along with a 25-year linear power output warranty, guaranteeing at least around 80% of nominal power after 25 years of operation. Since the series has been discontinued, buyers should ask the seller for the current warranty card and confirm who handles claims now that production of this model has ended.
Are TS275-60P panels suitable for a pitched roof on a single-family home?
Yes, the 275 Wp rating in a 60-cell format is a compact, standard size compatible with typical mounting systems for pitched roofs, whether metal tile or ceramic tile roofing. The reinforced aluminum frame handles snow loads well, which matters when mounting on roofs with a shallow pitch angle under Polish climate conditions.
Do TS275-60P panels perform well in winter and low temperatures?
Yes, crystalline silicon modules, including polycrystalline units in the TS275-60P series, generally gain efficiency at low temperatures due to a positive voltage temperature coefficient - the colder it is, the higher the output voltage at the same power. This means good performance on sunny, cold days, though actual winter yield is still limited by shorter daylight hours and a lower sun angle.
How does the TS275-60P differ from Tescom Solar's newer bifacial panels?
The TS275-60P is a monofacial panel, generating power only from its front side, unlike newer bifacial designs that also capture light reflected off the ground. For a typical rooftop installation the practical difference is small, but for ground-mount or facade installations, bifacial panels can add an extra 5-15% yield that the TS275-60P cannot provide.
