SP Enerji SP Poly 72-cell photovoltaic panels provide a solid foundation for large commercial projects and solar farms, where the combination of efficiency and investment cost optimization is key. The use of polycrystalline technology in a 72-cell format allows for high module operation stability even in variable weather conditions. The design based on durable tempered glass and a reinforced frame guarantees increased resistance to snow loads and wind pressure, which directly translates into long-term reliability of the installation. Unlike smaller modules, this series significantly reduces expenditures on cabling and mounting systems, offering a reduced levelized cost of energy (LCOE). This solves the problem of high initial outlays when building professional PV power plants. Thanks to a precise cell surface texturing process, these modules effectively absorb diffuse light, which ensures stable energy yields even on cloudy days. This solution is primarily dedicated to investors building large-scale solar farms and to enterprises with large roof areas. This series stands out from the competition through an excellent price-to-power ratio, representing a sound choice wherever the priority is a quick return on investment and the technical reliability of components.

Common questions

6 answered
What warranty does the SP Enerji SP Poly 72-cell series come with?
SP Enerji provides a 10-year product warranty covering manufacturing defects and material faults, along with a 25-year linear power output warranty ensuring the module retains at least 80% of its rated efficiency over that period. Both warranties meet commercial-segment standards and form a reliable basis for long-term return-on-investment calculations in utility-scale PV projects.
Is the SP Poly 72-cell series a good fit for large-scale solar farm construction?
Yes, this series was specifically designed for utility-scale installations. The 72-cell format delivers up to 335 Wp per module, which directly reduces the number of panels, cable runs, and mounting hardware required per MWp. Fewer components per installed kilowatt-peak translates into lower BoS costs and a better LCOE compared to builds based on smaller 60-cell modules.
What does PERC technology mean in the SP Poly 72-cell panels and why does it matter?
PERC stands for Passivated Emitter and Rear Cell. A passivation layer is applied to the rear surface of the polycrystalline cell, reflecting photons that passed through without being absorbed back for a second conversion attempt. In practice, this yields 3–5% higher energy output compared to standard poly cells without rear passivation, while still maintaining the favorable price-to-power ratio typical of polycrystalline modules.
How do SP Poly 72-cell panels perform on overcast days typical of the Polish climate?
Thanks to precision cell surface texturing and PERC technology, these modules efficiently absorb diffuse irradiance, not only direct sunlight. In Poland, diffuse radiation accounts for a substantial share of annual energy yield, so this characteristic results in stable power generation even under heavy cloud cover. The reinforced aluminum frame and tempered glass also provide reliable protection against snow load and wind pressure.
Why does the SP Poly 72-cell series use 72 cells instead of the standard 60, and what does that mean for installers?
The 72-cell format is engineered for commercial and industrial-scale installations. Arranging cells in a 6×12 configuration raises individual module power up to 335 Wp. For investors building solar farms or covering large warehouse rooftops, fewer modules per kWp means tangible savings on BoS components, wiring, and installation labor, which directly lowers the overall system cost.
Where is SP Enerji headquartered and do SP Poly 72-cell modules carry recognized certifications?
SP Enerji is a Turkish PV module manufacturer. Turkey is one of the fastest-growing solar production hubs in the EMEA region. Modules intended for European markets are typically tested and certified to IEC 61215 and IEC 61730, confirming both electrical safety and the mechanical durability of the construction required for professional solar farm design.
