The SpolarPV SPV560-PM10-144 series photovoltaic modules utilize advanced Half-Cut cell technology, which significantly reduces energy losses resulting from internal resistance and partial shading. Thanks to the use of Multi-Busbar cells, this design guarantees better current distribution and higher resistance to micro-cracks, ensuring operational stability for decades. The use of 144 monocrystalline cells translates into high power density, allowing for the maximum utilization of available mounting space. This solution focuses on minimizing LCOE costs, making it primarily dedicated to commercial, industrial, and large-scale solar farm investments. What distinguishes this series from standard solutions is the exceptionally favorable power temperature coefficient, allowing for high energy generation efficiency even during summer heat. Solid construction and resistance to harsh weather phenomena ensure that these panels perform excellently in variable climatic conditions typical of Poland. Investors receive equipment that combines modern technical thought with reliability, representing an economically justified alternative to the most expensive brands while maintaining the highest performance standards.

Common questions

6 answered
What warranty comes with the SpolarPV SPV560-PM10-144 panels?
SpolarPV provides a 12-year product warranty and a 30-year linear power output warranty for the SPV560-PM10-144 series. The 30-year power warranty guarantees the module will retain a minimum output level for three decades, which is essential when calculating the LCOE and overall return on investment for commercial or industrial projects.
Are the SpolarPV SPV560-PM10-144 modules suitable for a large-scale solar farm?
Yes, the SPV560-PM10-144 series is specifically designed for commercial, industrial, and utility-scale solar farms. With a peak output of 560 Wp and 144 monocrystalline cells per module, it delivers high power density, reducing the total number of modules needed and lowering overall BoS costs per installed MW.
What is half-cut PERC technology and is it worth choosing in the SPV560-PM10-144 series?
Half-cut cells are produced by slicing standard cells in half, which reduces internal resistance and resistive losses. PERC adds a passivated rear layer that reflects unused light back through the cell for a second absorption pass. Combined with Multi-Busbar design, these technologies improve shade tolerance, reduce the risk of microcracks, and contribute to a longer module lifespan.
How do the SpolarPV SPV560-PM10-144 panels perform on hot summer days?
The SPV560-PM10-144 series features a favorable temperature coefficient of power, meaning output drops less per degree Celsius of cell temperature rise compared to standard modules. This is a key advantage during summer heatwaves, helping maintain stable energy generation and improving annual yield in climates with high seasonal temperatures.
Are the SpolarPV SPV560-PM10-144 panels monofacial or bifacial?
The SpolarPV SPV560-PM10-144 modules are monofacial, meaning they generate electricity only from light hitting the front surface. They do not feature bifacial technology. This makes them a cost-effective solution for the majority of rooftop and ground-mounted installations where rear-side irradiance gain would be minimal or the bifacial premium is not justified.
Is SpolarPV a Tier 1 manufacturer and does it affect the investment risk?
SpolarPV is not currently listed as a Tier 1 manufacturer by financial rating agencies such as BloombergNEF. This is worth considering if you are seeking project financing or specific insurance products that require Tier 1 qualification. That said, the SPV560-PM10-144 series carries a 30-year power warranty and competitive technical specifications — verify warranty enforcement terms with your local distributor before purchasing.
