The MAXLUMI 300kW Agrivoltaic Fixed-Tilt System represents a transformative integration of renewable energy generation with modern agriculture. This innovative solution addresses the critical issue of land scarcity by creating a dual-use system in which a 300 kWp solar plant coexists with active crop cultivation. By elevating the solar array to a height of 4 meters, the system provides ample clearance for the free movement of agricultural machinery and personnel while offering partial shade that protects crops, reduces moisture evaporation, and improves yields for certain plant species. Engineered for a service life of more than 25 years, the system uses state-of-the-art bifacial solar modules and a robust steel structure to deliver a levelized cost of energy (LCOE) competitive with conventional ground-mount installations, making it both a financially viable and environmentally responsible investment. The system complies fully with international standards including IEC 61215 for module performance and UL 1703 for safety, ensuring reliability and bankability for commercial farm owners and renewable energy investors.
The 300 kW Agrivoltaic System is an integrated solution composed of three primary subsystems: the solar generation block, the elevated fixed-tilt mounting structure, and the power-conversion system. Each component is selected for maximum efficiency, durability, and seamless integration with the agricultural environment.
At the core of the system is a high-performance array of bifacial solar modules featuring state-of-the-art Tunnel Oxide Passivated Contact (TOPCon) technology. Rated at more than 700 W per module with a front-side efficiency of 22%, these panels are market leaders in performance. The bifacial design captures sunlight reflected from the ground (albedo) on the rear of the module, increasing total energy harvest by an additional 10% to 30% compared with monofacial panels. This rear-side gain is particularly effective across the varied surfaces typical of agricultural sites. The system uses approximately 429 modules, with a total module area of about 1,340 square meters. The modules are certified to IEC 61215 (design qualification and type approval) and IEC 61730 (photovoltaic module safety qualification), ensuring resistance to Potential Induced Degradation (PID) and durability against harsh environmental conditions such as hail and heavy snow.
The defining feature of this agrivoltaic system is its specialized mounting structure. The solar array is installed on a rugged fixed-tilt frame fabricated from high-strength hot-dipped galvanized steel, elevated to a height of 4 meters. This substantial clearance allows standard agricultural equipment — from tractors to small harvesters — to pass freely beneath the array, ensuring farm operations can proceed without interruption. The optimized fixed-tilt design provides a cost-effective, low-maintenance solution; with no moving parts, it delivers outstanding reliability over the system's 25-plus-year lifetime. The full structure is engineered to withstand local wind and snow loads per regional building codes and standards such as ASCE 7-16, providing a safe foundation for a half-megawatt generating plant.
To efficiently convert the DC power generated by the solar modules into grid-compatible AC power, the system uses multiple commercial string inverters. For a 300 kW configuration, this approach delivers superior reliability and easier maintenance compared with a single central inverter. These inverters feature multiple Maximum Power Point Trackers (MPPTs) to optimize energy harvest across different sections of the array and mitigate production losses from shading or module mismatch. The inverters meet the stringent requirements of IEC 62116 and IEEE 1547, ensuring anti-islanding protection and stable grid interaction. The full AC infrastructure — including switchgear and transformers — is designed for seamless interconnection to the local utility grid at typical commercial voltages (usually 480 V).
The 300 kW system is engineered for high-yield energy production and substantial positive environmental impact. Assuming moderate solar irradiance (e.g., 1,800 kWh/kWp/year) and an average bifacial gain of 15%, the system is expected to generate approximately 621 MWh of clean electricity per year. This represents a high capacity factor of around 23.6%, demonstrating the system's efficiency. The total land area required is approximately 2,500 square meters, representing a level of land-use efficiency impossible to achieve with separate solar and agricultural projects. Each year, the system offsets approximately 248 metric tons of CO₂ emissions (based on the U.S. average grid factor) — the equivalent of removing more than 50 gasoline-powered vehicles from the road annually. With a projected LCOE below $0.03/kWh at optimal sites, combined with a simple payback period of 7 to 10 years, the system represents an attractive financial asset.
The dual-use nature of the system provides tangible benefits for crop cultivation. The partial shade created by the elevated solar panels reduces plant heat stress and lowers soil-moisture evaporation by up to 30%, an advantage especially valuable in arid or semi-arid climates. These microclimate changes are ideal for a wide range of shade-tolerant crops including leafy greens, vegetables (e.g., lettuce, broccoli), and berries. The 4-meter clearance and wide support structure ensure that farming practices — from sowing to harvest — can proceed with minimal disruption. The Land Equivalent Ratio (LER) of such systems often exceeds 1.5, meaning that the combined output of electricity and crops from the same land is 50% greater than what each use would have produced separately.
Q1: What is the total installed cost, and what does it include?
A1: Pricing for the turnkey 300 kW Agrivoltaic Fixed-Tilt System is available upon inquiry. This package includes the high-efficiency bifacial modules, the 4-meter elevated steel mounting structure, the string inverters, and all electrical-system hardware. It also covers Engineering, Procurement, and Construction (EPC) services as well as grid-interconnection costs. The final price varies with site-specific geotechnical conditions, local labor rates, and interconnection requirements.
Q2: What impact does the elevated structure have on farming operations?
A2: The system is purpose-built to integrate seamlessly with farming. The 4-meter vertical clearance and wide-spaced support columns provide ample room for most standard agricultural machinery — tractors, sprayers, and the like — to operate unobstructed beneath the panels. This ensures essential agricultural activities such as soil preparation, sowing, irrigation, and harvesting can continue efficiently. The structure's land footprint is minimized to maximize available cultivation area.
Q3: What maintenance does the system require?
A3: The system is designed for low maintenance. The fixed-tilt structure has no moving parts and requires no mechanical service. The primary maintenance activity is periodic cleaning of the solar modules (1–2 times per year depending on local soiling) to ensure optimal performance. The string inverters are modular and easily replaceable should a failure occur. A remote monitoring system included in the package continuously tracks performance and provides alerts for any potential issues.
Q4: How does panel shading affect crop yield?
A4: The impact of shading depends on the crop. For shade-tolerant crops such as lettuce, spinach, and various berries, the partial shade can improve quality and yield while reducing water requirements, protecting plants from excessive sunlight and heat. For sun-preferring crops, yield may decrease. We perform a detailed crop-compatibility analysis for each project to ensure that the selected crops are well suited to the specific microclimate created by the solar array.
Q5: What are the main safety and certification standards for the system?
A5: The full system is designed to meet stringent international safety and performance standards. The solar modules are certified to IEC 61215 and UL 1703/IEC 61730 for design, performance, and safety. The inverters comply with IEC 62116 and IEEE 1547 for grid safety and interconnection. The structural components are designed per local building and electrical codes, ensuring the system is safe, reliable, and fully bankable over its entire operating life.
