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.

What owners get
Purpose-built for agrivoltaics

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 technology

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.

30-year power warranty

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.

Tier-1 bankable manufacturer

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.

Robust mechanical build

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.

Trade-offs
Below-average efficiency vs peers

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.

Notes from the database
  • Efficiency of 15.4% is 6.6pp below the TOPCon 400-450W median (22.0%)
  • 153.7 W/m² power density is 66.5 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
  • At 33.7 kg (11.7 kg above TOPCon 400-450W median of 22.0 kg), requires checking roof load capacity
  • 80% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces

About the Terra E series

6 answered

These answers cover the whole series. Where a figure differs, the specification above is this module's own.

How do Terra E CMER-88BD panels differ from standard solar panels used on residential roofs?
Terra E panels are bifacial modules built with a dual-glass design that allows up to 40% light transmission. Standard residential panels have an opaque backsheet and generate power from only one side. The partial transparency of Terra E lets crops grown underneath still receive adequate sunlight, making this series primarily suited for agrivoltaic installations and greenhouse roofs rather than typical residential roofs.
What warranty comes with Terra E CMER-88BD panels and what does it cover?
AE Solar provides a 15-year product warranty and a 30-year linear power warranty. This means the manufacturer commits to repairing or replacing defective modules for 15 years, while guaranteeing a minimum power output level for 30 years, with output declining at a small, defined annual rate. This warranty length is typical of tier 1 manufacturers and reflects the stability of the TOPCon technology used in this series.
What is n-Type TOPCon technology, and is it worth paying more for Terra E panels that use it?
TOPCon (Tunnel Oxide Passivated Contact) is a newer n-Type cell technology that reduces surface energy losses and achieves higher efficiency than conventional PERC cells. Terra E panels also use half-cut cells, which lower electrical resistance and improve shade tolerance. The higher price pays off through better long-term performance and lower power degradation, since the design is free from LID and LeTID effects.
What is the maximum power output of the Terra E CMER-88BD series?
Panels in the Terra E CMER-88BD series reach a maximum power output of up to 430 Wp. Thanks to bifacial technology, real-world energy yield can exceed this rated value, since additional energy is captured from reflected light hitting the rear side of the module, such as from the ground beneath an agrivoltaic structure.
Are Terra E panels suitable for installation over farmland crops or on a greenhouse roof?
Yes, that is their primary intended use. The dual-glass bifacial design with up to 40% light transmission ensures crops underneath receive the sunlight they need, while the durable anodized aluminum frame and tempered glass protect crops from hail, strong wind, and heavy rainfall. This makes it a solution specifically engineered for agrivoltaics and greenhouse mounting rather than standard rooftop installations.
Who manufactures the Terra E series, and is it a reliable brand in the solar market?
The Terra E series is manufactured by AE Solar, a company headquartered in Germany and classified as a tier 1 manufacturer, indicating strong financial stability and a long-standing market presence. This status matters for long-term warranties, as it increases the likelihood that the manufacturer will be able to honor warranty commitments throughout the full 30-year period.
