Solid all-round for its segment
The HiDM-Black series consists of fully black photovoltaic modules designed for rooftops where aesthetics matter just as much as performance. Featuring high-density mono-PERC cells, the panel maximizes the available light-absorption area, translating into higher energy yield per square meter of module surface. The black frame, black backsheet, and uniform cell matrix allow the panel to blend seamlessly into the roof, eliminating the visible white gaps between cells found in cheaper solutions. The manufacturer also focused on reliability under demanding conditions - lower internal current and reduced hot-spot temperature limit the risk of degradation under partial shading, while the design minimizes the impact of micro-cracks on long-term output. The panel withstands extreme mechanical loads, including heavy snow and strong wind, making it a solid choice even in harsher climates. The whole series is backed by a 25-year linear power output warranty, giving investors confidence in stable returns over decades. This solution is aimed primarily at residential installations, where both visual appeal and long-term energy efficiency are equally important.

Residential.
Black frame, black backsheet and a uniform cell matrix eliminate the visible white strips found in lower-cost modules, making the series an attractive choice for residential installations where roof appearance matters.
Canadian Solar is a bankable Tier-1 manufacturer founded in 2001 in Canada, reducing supplier-bankruptcy risk and easing project financing through banks and leasing institutions.
The series carries a 25-year linear power warranty alongside a 15-year product warranty, which at launch (2018) was a premium-tier standard for PERC modules, giving investors predictable long-term returns.
Lower internal current and reduced hot-spot temperature limit cell degradation risk under partial shading, while the design minimizes the impact of microcracks on long-term energy yield.
High-packing-density mono-PERC cells achieve up to 20.2% efficiency and 340 Wp of power, maximizing energy harvest per available roof area on constrained mounting surfaces.
The HiDM-Black series has been discontinued - limited availability of warranty service, spare parts, and matching replacement modules for repairs or system expansion may pose a risk for investors.
Peak efficiency of 20.2% lags comparable models - Resun RS6K-M FULL BLACK (20.15%) and MWG Mono (20.12%) are close, but Panasonic HIT.+ N340/N335, using heterojunction (HJT) technology, reaches 20.3% with a better temperature coefficient than PERC.
The module lacks bifacial capability, limiting additional energy yield from reflected light compared to newer double-sided panels, particularly in installations over bright roof or ground surfaces.
- At 19.6% efficiency, this panel is on par with typical PERC 0-400W modules
- At 195.7 W/m² power density, roof space requirements are typical for PERC 0-400W panels
- Temperature coefficient of -0.37%/°C matches the PERC 0-400W median
- 19.2 kg weight - 1.3 kg lighter than PERC 0-400W median (20.5 kg), reducing installation effort
- In the top 90% for efficiency among all PERC panels
