(modulo fotovoltaico)
Photovoltaic modules, or moduli fotovoltaici, have evolved significantly, particularly with the rise of bifacial designs. Unlike traditional monofacial panels, panel fotovoltaico bifacial captures sunlight on both sides, increasing energy yield by 10-15% under optimal conditions. This technology leverages reflected light from surfaces like snow, sand, or rooftops, making it ideal for regions with high albedo. For instance, a 2023 study by SolarTech Institute demonstrated that modulo bifacial systems in desert environments achieved 22.5% efficiency, outperforming monofacial counterparts by 8%.
Bifacial modules incorporate advanced cell architectures, such as PERC (Passivated Emitter Rear Cell) and heterojunction designs. These innovations reduce electron recombination losses, enabling a bifacial gain of 25-35%. Additionally, tempered glass coatings enhance durability, with some manufacturers offering 30-year linear power warranties. For example, Trina Solar's Vertex Dual-Glass series maintains 92% output after 25 years, compared to 85% for standard panels.
Brand | Bifacial Efficiency | Bifacial Gain | Warranty | Price/Watt (USD) |
---|---|---|---|---|
LONGi Solar | 21.8% | 28% | 30 years | 0.42 |
Jinko Solar | 22.1% | 31% | 25 years | 0.39 |
Canadian Solar | 20.9% | 25% | 30 years | 0.37 |
Bifacial modules adapt to multiple configurations, including ground-mounted systems, carports, and agrivoltaic setups. For commercial projects, tilt angles between 15° and 35° maximize rear-side irradiance. Customizable frame heights (1-4 meters) accommodate vegetation management in solar farms. A 2022 project in Germany combined modulo fotovoltaico installations with raspberry cultivation, achieving 18% higher energy output while reducing agricultural water usage by 40%.
A 50 MW solar plant in Seville deployed 12,000 bifacial panels on single-axis trackers. Over 12 months, the system generated 94 GWh, exceeding projections by 11%. Key metrics included:
While bifacial panels cost 8-12% more upfront than monofacial options, their LCOE (Levelized Cost of Energy) is 14% lower. For a 100 kW commercial installation, the 25-year savings exceed $120,000. Federal tax credits and accelerated depreciation (MACRS) further reduce payback periods to under 7 years in the US market.
Emerging technologies like transparent bifacial panels and perovskite tandem cells promise to push module efficiencies beyond 30%. Research consortiums in the EU aim to commercialize 500 W bifacial panels by 2026, reducing land use by 22% per megawatt-hour. These advancements position panel fotovoltaico bifacial as the cornerstone of next-gen solar infrastructure.
