In the Polish climate, with a panel temperature of approximately 65°C, this translates to a real increase of approximately 1.5-2% in power output compared to previous-generation modules. This technology also eliminates the LID (Light-Induced Degradation) phenomenon that is present in p-type silicon. - **Bifacial Dual Glass - maximize energy yield from both sides** - The construction of a double-pane glazing (2.0+2.0 mm glass/glass) allows for energy generation from the rear surface of the module, with an additional gain of approximately 25% when the ground albedo is above 25% (e.g., white gravel, light concrete). Compared to single-pane modules, the same ground area generates a realistically higher kWh output without increasing the land footprint. Dual Glass also provides IP68-level protection and resistance to PID (Potential Induced Degradation). - **30-year linear warranty ≥87.4%** - Astronergy guarantees a degradation of no more than 1% in the first year and no more than 0.4% per year for the following 29 years, with a minimum power output of ≥87.4% after 30 years. A competitor in the same power segment - Talesun BISTAR TP7F78M - offers standard warranty terms without such precise linear specifications, which translates into a higher Net Present Value (NPV) for the project. - **Efficiency of 22.5-23.2% compared to similar companies** - The upper end of the series' efficiency (23.2%) is on par with the leading performers in the comparative list - Tongwei TWMND N-type (23.2%) and Lexron TOPCon (23.23%) - and significantly exceeds Talesun BISTAR (21.5%). A higher W/m² directly reduces BOS (cabling, construction, and foundation) costs for each installed MW. - **Bankability BNEF Tier 1 - the top 6 producers globally** - Astronergy (part of the Chint Group) has secured a place in the top six of the BloombergNEF 2023 bankability ranking, with an annual production capacity of 56 GW (as of 2025). Tier 1 status is a formal requirement for financing PV farms with external bank debt - it eliminates the risk of the project being rejected due to due diligence by the financing bank. ## Cons - **Product warranty is only 15 years.** - Given the current market standard, where JA Solar, Jinko Solar, and Canadian Solar offer 25-year product warranties for utility-scale modules, Astronergy's 15-year warranty places it below the median for the premium segment. For projects with a 25-year financing horizon, this may require additional module insurance or renegotiation of terms with the financing bank. - **Weight: 32.1 kg - makes roof mounting difficult.** - The dual-glass construction increases the module's weight to 32.1 kg (compared to approximately 25-27 kg for standard monofacial modules in this power range). This requires verifying the roof's load-bearing capacity and necessitates at least a 2-person installation, which increases labor costs. The impact on ground-mounted installations is marginal. ## About this series Astronergy ASTRO N5 CHSM72N(DG)/F-BH series panels are an advanced solution based on **n-type TOPCon cells**, redefining performance standards in large-scale installations.

After 30 years of operation, the module is guaranteed to retain at least 87.4% of its initial rated power. ### Are the Astronergy ASTRO N5 bifacial panels suitable for utility-scale photovoltaic farms? Yes, the CHSM72N(DG)/F-BH series is specifically engineered for large-scale ground-mounted installations. With power output up to 600 Wp and a bifacial dual-glass construction, the module harvests energy from both faces, which on high-albedo surfaces (light gravel, snow, light-colored grass) can increase energy yield by 10-25%. A system voltage of up to 1500 V facilitates longer string configurations, reducing balance-of-system (BoS) costs and lowering the overall LCOE of the plant. ### How do the TOPCon cells in the ASTRO N5 differ from standard p-type PERC cells? The n-type TOPCon cells used in the ASTRO N5 achieve a module efficiency of approximately 22.8%, which significantly exceeds that of typical PERC modules (19-21%). The temperature coefficient is only -0.29%/°C, meaning the modules lose less power on hot days compared to p-type cells. TOPCon technology also exhibits lower light-induced degradation (LID) and light- and elevated temperature-induced degradation (LETID), effectively extending the real-world service life of the installation. ### Do the Astronergy ASTRO N5 CHSM72N(DG)/F-BH panels perform well under overcast skies and low-light conditions? Yes. N-type TOPCon cells demonstrate superior low-irradiance performance compared to conventional p-type PERC modules. This translates into higher energy yields during cloudy mornings and evenings, which are common in temperate climates. The manufacturer confirms a low temperature coefficient (-0.29%/°C), ensuring stable output in both summer heat and winter cold. ### What are the dimensions and weight of the ASTRO N5 CHSM72N(DG)/F-BH panels - are they difficult to transport and install?
