The use of **monocrystalline half-cut cells** minimizes current losses and helps stabilize production when the module is intermittently shaded - which is often the case for ground-mounted systems, agricultural areas, and installations near commercial buildings. A key feature of the series is **a design focused on resilience** and long-term performance in conditions of humidity, dust, and fluctuating temperatures, which makes it easier to maintain predictable energy yields over multiple seasons. These modules are also a good option for projects where **better shading tolerance** and the risk of localized overheating are important. This is a solution for investors and installers seeking **practical reliability** in PV farms, agro-PV systems, and demanding commercial systems. ## Notable figures - At 19.6% efficiency, this panel is 3.6pp above typical \*\*TOPCon 0-400W\*\* modules (median: 16.0%) - 135.9 W/m² power density is 23.9 W/m² below \*\*TOPCon 0-400W\*\* median (159.8 W/m²) - requires larger installation area - At -0.29%/°C, hot weather performance is typical for \*\*TOPCon 0-400W\*\* panels - At 27.0 kg, this panel is 3.5 kg heavier than the \*\*TOPCon 0-400W\*\* median (23.5 kg) - more demanding for installation crews - Ranked #12642 out of 14005 panels for efficiency in the database ## Questions ### What is TOPCon technology used in the Sun Earth AGRI Mono Half Cell modules and why is it worth choosing? TOPCon (Tunnel Oxide Passivated Contact) is an N-type cell technology offering higher efficiency and slower degradation compared to older PERC cells. In practice, this means better energy yield throughout the system's entire lifetime, especially at elevated temperatures. The Sun Earth AGRI Mono Half Cell series, equipped with TOPCon cells, delivers stable power output for decades, resulting in a lower LCOE for the investor. ### Are the Sun Earth AGRI Mono Half Cell panels bifacial, and how much extra energy can be gained from the rear side? Yes, Sun Earth AGRI Mono Half Cell modules are bifacial, generating energy from both sides of the cell. In ground-mounted and agrivoltaic installations where the ground surface reflects solar radiation, the rear side can contribute an additional few to over ten percent of power, depending on ground albedo. This effect is especially beneficial on light-colored soil, concrete surfaces, or in vegetation-rich environments. ### What warranty is offered for the Sun Earth AGRI Mono Half Cell series? The manufacturer provides a 12-year product warranty covering material and manufacturing defects, along with a 30-year linear power warranty. This means that after 30 years of operation the module should retain at least 87% of its original rated power, which is the standard for TOPCon modules. This is a key factor when calculating the return on investment for a PV farm or agrivoltaic system. ### Is the Sun Earth AGRI Mono Half Cell series suitable for agrivoltaic (agroPV) and ground-mounted installations? Yes, the AGRI series was designed specifically for ground-mounted and agricultural installations. The frameless double-glass construction provides resistance to moisture, dust, and varying temperatures typical of agricultural environments. Bifacial cells further increase yield by capturing reflected light from the ground or vegetation. The series performs well in both conventional PV farms and agrivoltaic systems that combine energy production with crop cultivation. ### How does the half-cut cell technology affect Sun Earth AGRI panel performance under partial shading? Half-cut cells divide a traditional PV cell into two smaller halves, reducing electrical resistance and minimizing current losses. Under partial shading from trees, poles, or building structures, the impact of shaded areas on the rest of the module is significantly lower than in panels with full-size cells. This results in more stable power output under challenging conditions and reduces the risk of local hot spots forming. ### What is the maximum power output of the Sun Earth AGRI Mono Half Cell module and which projects is it designed for? Modules in the Sun Earth AGRI Mono Half Cell series achieve a peak power output of up to 320 Wp. This specification is optimal for installations where durability and reliability in demanding environmental conditions take priority. The series is well suited for small to medium PV farms, agrivoltaic systems, and installations at agricultural and farm buildings where long-term stability is the primary requirement rather than maximizing per-unit wattage. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/2182mm-80Cells-320W-AGRI-PV-Module-a2946518cd63.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [JA Solar NS-300MH-72](https://comparepv.com/panel/ja-solar-ns-300mh-72) | 300 W | Lighter, +3.8 pp, -5 yr warranty | | [PolyCrown Solar Tech NS-300MH-72](https://comparepv.com/panel/polycrown-solar-tech-ns-300mh-72) | 300 W | Lighter, +3.8 pp, -5 yr warranty | | [Heckert Solar ZEUS 1.2 FullBlack 280W](https://comparepv.com/panel/heckert-solar-zeus-1-2-fullblack-280w) | 280 W | -40 W, lighter, +3.8 pp | | [JA Solar NS-330MH-80](https://comparepv.com/panel/ja-solar-ns-330mh-80) | 330 W | Lighter, +3.6 pp, -5 yr warranty | | [PolyCrown Solar Tech NS-330MH-80](https://comparepv.com/panel/polycrown-solar-tech-ns-330mh-80) | 330 W | Lighter, +3.6 pp, -5 yr warranty | | [Gamko New Energy GKA182M285W](https://comparepv.com/panel/gamko-new-energy-gka182m285w) | 285 W | -35 W, 16 kg lighter, +3.4 pp | | [Gamko New Energy GKA182M270W](https://comparepv.com/panel/gamko-new-energy-gka182m270w) | 270 W | -50 W, 16 kg lighter, +3.4 pp | | [Gamko New Energy GKA182M300W](https://comparepv.com/panel/gamko-new-energy-gka182m300w) | 300 W | -20 W, lighter, +3.4 pp | | [Gamko New Energy GKA210M320W](https://comparepv.com/panel/gamko-new-energy-gka210m320w) | 320 W | Lighter, +3.4 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | +240 W, cooler, +5.2 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | +235 W, cooler, +5.1 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | +230 W, lighter, +4.8 pp | | [Longi Solar LR7-60HVH-545M](https://comparepv.com/panel/longi-lr7-60hvh-545m) | 545 W | +225 W, cooler, +4.6 pp | | [Longi Solar LR7-60HVH-540M](https://comparepv.com/panel/longi-lr7-60hvh-540m) | 540 W | +220 W, cooler, +4.3 pp | --- Source: https://comparepv.com/panel/sun-earth-skt320m10 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
