Middle of its segment, modest efficiency
Photovoltaic panels from the Exiom EX345-365M(B)-96(HC)(182)AGR series introduce a new level of quality to the compact module segment, utilizing advanced silicon cells based on a 182 mm wafer. The use of Half-Cut technology in a specific 96-cell configuration allows for the optimization of electrical parameters, which directly reduces energy losses resulting from internal resistance. Thanks to the glass-glass (bifacial) construction, these modules offer significantly higher resistance to aging processes and PID degradation, ensuring stable yields for decades. This solution is primarily dedicated to demanding rooftop installations where limited space necessitates the use of high power density components. What sets this series apart from standard solutions is the innovative 10BB multi-busbar technology, which improves charge collection and minimizes the risk of cell micro-cracks. Additionally, exceptional efficiency in low-light conditions means that the panels generate energy more efficiently in the early morning and late afternoon. An investment in these modules is a guarantee of safety, confirmed by high resistance to extreme snow and wind loads, perfectly suited to the variable weather conditions in Poland. A technical approach to designing the cell structure translates into real savings and a faster return on investment by maximizing self-consumption in the daily cycle.

The dual-glass design eliminates the backsheet as a potential failure point, providing superior resistance to PID degradation and moisture ingress. Combined with bifacial cell technology, it enables additional energy yield from reflected irradiance (typically +5–15% depending on ground albedo), which is particularly valuable in agrivoltaic installations with high-reflectivity surfaces.
The 10-busbar (10BB) configuration on M10 (182 mm) cells reduces series resistance and minimizes the risk of microcracks compared to earlier 4–6 BB standards. The half-cut cell layout (96 HC cells) halves the operating current, thereby lowering resistive losses and improving performance under partial shading conditions.
The AGR suffix designates a dedicated series engineered for agrivoltaic installations, where the compact 96 half-cut cell layout allows flexible control of module density over crops. This is a rare specialization in the European market, setting the series apart from conventional rooftop products.
Exiom Solution S.A., headquartered in Spain, offers a shorter supply chain for the European market compared to Asian manufacturers, translating into potentially faster warranty service and greater availability of technical support within the EU. Iberdrola's investment in the Langreo (Asturias) manufacturing facility further strengthens the brand's production footprint in Europe.
The manufacturer provides a 25-year linear power output warranty, in line with the market standard for modules in this segment, giving investors a solid basis for 25-year financial modeling of the installation.
All three peer comparables achieve markedly higher efficiencies: DMEGC Greenhouse 15.37%, Sunket SKT345~365M10 18.7%, Solaria PowerXT 20.2%. The gap of 1.3–6.8 percentage points means that an installation of the same peak power requires between 10% and up to 50% more roof area compared to direct competitors in the same power class (345–365 Wp).
Manufacturer data indicates the absence of a tier_1_bankable classification, which may complicate or increase the cost of financing for projects requiring project bankability (project finance, institutional leasing). Banks and insurers frequently require modules from BNEF Tier 1-listed manufacturers as a condition for granting financing.
Founded in 2019, the company has a market track record of no more than seven years, which presents elevated risk in the context of a 25-year power output warranty. By comparison, leading manufacturers such as Solaria and DMEGC have operated for over a decade, and institutional investors typically require a documented financial history from panel manufacturers as a standard due-diligence requirement.
- Efficiency of 14.1% is 5.3pp below the PERC 0-400W median (19.4%)
- Power density of 142.4 W/m² is 52.0 W/m² below PERC 0-400W median (194.4 W/m²) - needs more roof space
- Temperature coefficient of -0.35%/°C matches the PERC 0-400W median
- Weight of 26.8 kg is 6.3 kg above PERC 0-400W median (20.5 kg) - verify structural support
- Bifacial design (10% factor) captures reflected light - adds 0-2% yield on ground-mount or white roof
