The SOLID Agro series represents SoliTek's response to the growing demand in the agrivoltaics market - panels specifically designed for agricultural, greenhouse, and above-crop applications. A key feature of this series is enhanced glass transparency, which allows a significant portion of natural sunlight to reach plants growing beneath the panels. This enables the simultaneous generation of energy and agricultural production on the same land area - without sacrificing crop yields. The glass-glass construction with TOPCon N-type cells guarantees exceptional durability in harsh environmental conditions - the modules exhibit increased resistance to ammonia, common in agricultural environments, as well as to sea spray in coastal areas. Bifacial cells allow for energy capture from both the front and back of the panel, increasing the overall energy yield of the installation. SOLID Agro also functions as a natural crop protection - shielding plants from hail, excessive sunlight, and high temperatures, which can reduce the need for irrigation water. This solution is for farmers, agrivoltaic investors, and greenhouse operators seeking synergy between food production and renewable energy generation. The 30-year manufacturer's warranty confirms the certainty of a long-term investment.

About the SOLID Agro series

6 answered

These answers cover the whole series. Where a figure differs, the specification above is this module's own.

How much light do SoliTek SOLID Agro panels transmit to crops growing beneath the installation?
SoliTek SOLID Agro panels feature increased glass transparency of approximately 35-40%, meaning a significant portion of natural sunlight reaches the plants below the modules. This allows crops to retain adequate light access while energy is produced simultaneously on the same land area, making true agrivoltaic operation feasible without a critical reduction in agricultural yield.
What warranty does SoliTek SOLID Agro come with and what does it cover?
SoliTek provides a 30-year product warranty and a 30-year power output warranty for the SOLID Agro series. After 30 years of operation, the panel is guaranteed to retain at least 87% of its rated power output. This extended warranty is supported by the durable glass-glass construction and N-type TOPCon cells, which exhibit a lower long-term degradation rate than standard PERC technology.
Are SOLID Agro panels resistant to ammonia and salt mist - can they be installed near livestock buildings or coastal sites?
Yes. The SOLID Agro series has passed ammonia resistance testing (relevant to livestock farming environments and manure exposure) as well as salt mist testing, making it suitable for both farm building installations and coastal locations. The frameless glass-glass construction eliminates edge corrosion risk associated with aluminum frames and reduces debris accumulation on module surfaces.
How does a bifacial SOLID Agro module technically differ from a standard monofacial panel?
The bifacial cells in the SOLID Agro series capture energy from both the front side (direct solar irradiance) and the rear side (albedo light reflected from soil, mulch, or other light-colored surfaces). Depending on ground reflectivity and installation height, rear-side gain can increase total energy yield by several to over ten percent compared to a monofacial module with the same 290 Wp nameplate rating.
Can SoliTek SOLID Agro panels withstand hail and strong winds above agricultural fields?
The SOLID Agro series is rated to IEC hail class 4 (hailstones up to 40 mm in diameter) and is engineered to withstand wind loads up to 5,400 Pa and snow loads up to 10,500 Pa. This is particularly important for agrivoltaic installations mounted over crops, where the modules simultaneously serve as weather protection for plants, mitigating hail damage risk and reducing heat stress from excessive solar radiation.
Is the SoliTek SOLID Agro series suitable for greenhouse integration and what are the mounting requirements?
Yes, SOLID Agro is designed with greenhouse and polytunnel applications in mind. The frameless glass-glass construction (3.2+3.2 mm tempered glass) allows modules to be integrated as a structural roofing element in greenhouses, transmitting enough light for light-dependent crops. Installation requires a purpose-built mounting structure with point-fixing clamps compatible with frameless bifacial modules.
