The SoliTek SOLID Agro Frameless series are photovoltaic panels designed specifically for agrovoltaic installations - combining energy production with crop cultivation on the same land. The frameless glass-to-glass design, with a 40% light transmission rate, allows the modules to function as an intelligent roof over crops, protecting them from excessive sunlight and adverse weather conditions while still allowing the necessary light spectrum for photosynthesis to pass through. The use of N-type cells in a bifacial configuration allows for energy generation from both sides of the panel, increasing the overall efficiency of the installation. The frameless design eliminates areas for dirt and moisture accumulation, and the glass-to-glass construction provides resistance to agricultural chemicals, including ammonia, as well as to marine and saline conditions. The modules have the highest hail resistance rating (class 4) and are covered by a 30-year manufacturer's warranty, maintaining at least 87% of their original power output. This solution is specifically designed for farms, orchards, and plantations where land is too valuable to be used for only one purpose.

Common questions

6 answered
Can SoliTek SOLID Agro Frameless panels be installed directly above crops?
Yes, the SOLID Agro Frameless series was specifically engineered for agrivoltaic installations where panels serve as a canopy over fields, orchards, and plantations. The frameless glass-glass design with 40% light transmittance allows plants to photosynthesize while shielding them from excessive solar radiation and adverse weather. The land beneath the array can remain in active agricultural use at the same time.
What warranty does SoliTek offer on the SOLID Agro Frameless series?
SoliTek provides a 30-year product warranty and a 30-year power output warranty on the SOLID Agro Frameless series. Throughout that period the manufacturer guarantees a minimum of 87% of the nominal rated power. This is among the longest warranties available on the market and is particularly relevant for agrivoltaic projects with extended payback horizons.
Are SoliTek SOLID Agro Frameless panels suitable for use near barns or poultry houses where ammonia levels are high?
Yes, the glass-glass frameless construction is resistant to chemical corrosion, including ammonia emitted in livestock facilities. The absence of an aluminum frame also eliminates crevices where moisture and bird droppings accumulate. The modules are additionally certified for marine and saline environments, confirming their durability under chemically aggressive conditions common in farming operations.
What is TOPCon bifacial technology and why does it matter for an agrivoltaic system?
TOPCon refers to N-type cells with a tunnel oxide passivation layer, delivering higher efficiency and a lower temperature coefficient than standard PERC cells. Bifacial means the panel generates power from both sides: the front captures direct irradiance while the rear harvests light reflected from soil or vegetation. In agrivoltaic setups where modules are elevated above the ground, the bifacial gain translates into a measurable increase in energy yield.
What is the hail resistance rating of the SoliTek SOLID Agro Frameless panels?
The SOLID Agro Frameless series has achieved the highest hail resistance rating, Class 4, per IEC 61215. This means the modules withstand impact from 55 mm diameter hailstones at speeds exceeding 30 m/s. The dual tempered glass construction without an aluminum frame further enhances mechanical integrity during storms, which is especially critical for exposed agricultural sites.
What is the maximum power output of SoliTek SOLID Agro Frameless panels and how does it affect agrivoltaic ROI?
Panels in the SOLID Agro Frameless series reach up to 300 Wp. Thanks to TOPCon cell technology and bifacial design, real-world energy harvest exceeds what the STC power rating alone suggests, as the rear side captures diffuse and ground-reflected irradiance. Combined with the 30-year manufacturer warranty, these modules support a predictable, long-term return on investment for agrivoltaic projects.
