Middle of its segment, heavy for its output
The Terra E CMER-88BD series is a solar panel lineup purpose-built for agrivoltaics, the pairing of crop farming with solar power generation. These modules feature a bifacial double-glass design, generating energy from both sides of the panel while still letting through the light plants underneath need to grow. The defining feature of the series is up to 40% light transmission, ensuring even light distribution across crops and reducing the risk of overheating or light deprivation, which makes these panels a natural fit for agri-PV installations and greenhouse roof mounting. The n-Type TOPCon technology with half-cut cells delivers higher efficiency and lower energy losses compared to conventional PERC cells, while the LID- and LeTID-resistant design limits power degradation over time. Built with an anodized aluminum frame and tempered glass, the panels withstand heavy mechanical loads, hail, wind, and snow, protecting crops from sudden rainstorms, hailstorms, and frost. The manufacturer backs the series with a 30-year performance warranty, reflecting long-term output stability. Terra E is a solid choice for farmers, investors, and agrivoltaic project developers seeking panels that combine high energy yield with real protection and support for crop production.

Bifacial glass-glass construction with up to 40% light transmission allows even illumination of crops grown beneath the array, making Terra E CMER-88BD a dedicated solution for agri-PV installations and greenhouse rooftop mounting rather than a standard ground-mount panel repurposed for the segment.
N-type TOPCon half-cut cells show lower LID and LeTID degradation and reduced energy losses compared to conventional PERC cells, translating into higher annual yield and more stable output under high-temperature conditions.
The manufacturer backs the series with a 30-year power warranty alongside a 15-year product warranty, exceeding the standard 25-year power warranty offered by many tier-1 competitors.
AE Solar is a German manufacturer founded in 2003 and holds BloombergNEF Tier 1 status for five consecutive years (17th recognition as of Q1 2026), alongside Wood Mackenzie Grade A and SMM Tier 1 ratings, reducing bankability risk for warranty servicing.
The anodized aluminum frame and tempered glass provide high resistance to snow and wind loads as well as hail impact, an important protective factor for crops cultivated beneath the panels during severe weather events.
Efficiency of 15.19-15.93% is markedly lower than comparable tier-1 modules of similar power class (Silfab Elite 21.9%, EGing STAR Pro 22.02%, Boviet GAMMA 19.8%, all at the same 430 Wp max power). This means a significantly larger module footprint is needed for the same power output, raising racking costs and land use per hectare of installation.
- At 15.6% efficiency, this panel is 6.4pp below the TOPCon 400-450W median of 22.0%
- 155.6 W/m² power density is 64.6 W/m² below TOPCon 400-450W median (220.2 W/m²) - requires larger installation area
- Temperature coefficient of -0.29%/°C matches the TOPCon 400-450W median
- Weight of 33.7 kg is 11.7 kg above TOPCon 400-450W median (22.0 kg) - verify structural support
- Bifacial design (80% factor) captures reflected light - adds 4-12% yield on ground-mount or white roof
