Solar Power Vietnam photovoltaic panels from the SPVXXX-66SN210 series represent a technological breakthrough in the large-scale installation sector, basing their design on 210 mm silicon cells. The use of such large wafers allows for achieving a unit power exceeding 700 Wp, which directly translates into a smaller number of modules needed to obtain the planned farm capacity. A key distinguishing feature of the series is N-type TOPCon technology, which, compared to traditional P-type cells, offers significantly better resistance to LID degradation and higher energy yield at high temperatures. Thanks to the bifacial dual-glass construction, these systems effectively utilize reflected light, which in optimal ground conditions generates a significant additional energy profit. The utilized SMBB (Super Multi-Busbar) architecture improves current flow and increases mechanical resistance to micro-cracks, which is critical during long-term operation in difficult weather conditions. This series addresses the problem of high balance of system (BOS) costs, reducing expenditures on cabling and mounting structures. It is a solution dedicated to professional investors and photovoltaic farm developers seeking maximum profitability and a 30-year power output warranty. This is an uncompromising proposition that stands out from the competition with unprecedented power density and the highest durability in the long-term perspective.

Common questions

6 answered
What is the maximum power output of Solar Power Vietnam SPVXXX-66SN210 panels?
The SPVXXX-66SN210 series delivers up to 735 Wp per module, achieved through large-format 210 mm silicon wafers. This high watt-per-module rating means fewer modules are required to reach the target farm capacity compared to standard 400–500 Wp panels, directly reducing balance-of-system (BoS) costs for racking structures and cabling.
What warranties come with the SPVXXX-66SN210 — product and power output?
Solar Power Vietnam provides a 12-year product warranty covering material and workmanship defects, plus a 30-year linear power output warranty. The extended power warranty is critical for utility-scale PV investors, as it supports reliable long-term energy yield projections and simplifies project bankability assessments with lenders and financial institutions.
Does the N-type TOPCon technology in the SPVXXX-66SN210 series actually reduce panel degradation?
Yes. N-type TOPCon cells are significantly less susceptible to light-induced degradation (LID) than conventional P-type PERC cells. This means lower power losses in the initial years of operation and better performance retention across the full 30-year warranty period. TOPCon also delivers superior temperature coefficients, maintaining higher output efficiency during peak solar irradiance on large ground-mounted farms.
Do the bifacial dualglass modules in the SPVXXX-66SN210 series pay off on a grass-surface ground-mounted farm?
Bifacial modules capture reflected irradiance from the ground surface. Grass typically has an albedo of 15–25%, which — with proper module clearance height of roughly 0.5–1 m above ground — translates into a measurable energy yield gain. Compared to monofacial panels, the bifacial gain can range from a few to over ten percent, meaningfully improving the overall LCOE of the investment.
Is Solar Power Vietnam a Tier 1 manufacturer, and does it matter for project financing?
Solar Power Vietnam is not currently listed as a Tier 1 manufacturer by agencies such as Bloomberg NEF. For projects relying on bank financing or leasing, this may require additional documentation — such as factory inspection reports or extended insurance policies — to meet lender acceptance criteria. Investors should verify module eligibility with their financing institution during due diligence before signing any EPC contract.
How does the SMBB architecture in the SPVXXX-66SN210 panels affect long-term durability?
Super Multi-Busbar (SMBB) technology uses a higher number of thinner busbars across the cell surface. Shorter current paths reduce resistive losses and — more importantly — lower mechanical stress within the cell, reducing the risk of microcracks. Over decades of thermal cycling (day/night, seasonal temperature swings), this directly translates to slower degradation and sustained output performance throughout the full 30-year power warranty.
