The Sunplus Hi-Max series focuses on maximizing energy yield even when the roof or ground is not ideal - in variable sunlight, partial shading, and in installations where long-term stability is crucial. The modules utilize modern half-cut cell technology and refined connections, minimizing losses and better handling micro-shading. This translates to more predictable energy production in real-world operating conditions, rather than just in a laboratory setting.

A key feature of Hi-Max is the combination of bifacial construction with glass-glass technology, which improves resistance to environmental factors and supports long-term reliability. Additionally, Micro Gap Design is used, which enhances tolerance to shading and facilitates maintaining high efficiency in dense environments.

This is a good choice for installers and investors seeking high durability in residential, commercial, and larger ground-mounted projects - particularly where hassle-free operation and reliable energy yield are important.

Common questions

6 answered
How does HJT cell technology in Sunplus Hi-Max panels differ from classic PERC cells?
HJT (heterojunction) cells combine a crystalline silicon layer with thin amorphous silicon layers, reducing thermal losses and improving efficiency at higher temperatures compared to PERC. In practice, Hi-Max panels lose power more slowly on hot days and perform better under variable irradiance, resulting in higher real-world annual energy yield.
Are Sunplus Hi-Max panels suitable for installations with partial shading?
Yes, this is one of the series' main strengths. The half-cut cell architecture combined with Micro Gap Design increases shade tolerance from chimneys, antennas, or trees, limiting the impact of individual cell power drops on the whole module string. As a result, energy production stays more stable even under difficult mounting conditions.
What is the maximum power output of the Hi-Max series and what installations does it suit?
Hi-Max panels reach up to 750 Wp, making them a strong choice for both large commercial rooftop installations and ground-mounted solar farms. High per-module power output reduces the number of panels needed to reach a target system capacity, lowering mounting structure and labor costs.
What is bifacial construction and is it worth paying extra for Hi-Max double-sided panels?
Bifacial construction means the panel generates energy from both the front and rear side, capturing light reflected off the ground surface. In the Hi-Max series this is combined with glass-glass technology, further improving module durability. The extra cost makes sense especially for ground-mount installations over light-colored surfaces or elevated racking, where rear-side gain can reach several percent additional yield.
What is the power warranty on Sunplus Hi-Max panels?
The Hi-Max series comes with a 30-year power warranty, well above the typical industry standard of 25 years. This extended coverage stems from the glass-glass construction, which protects the cells against moisture ingress and degradation better than standard back-sheet panels, resulting in a slower power decline over time.
Are Hi-Max panels resistant to moisture and harsh weather conditions?
Yes, thanks to glass-glass technology the module is sealed on both sides with glass layers instead of a standard rear polymer back-sheet, significantly reducing moisture penetration and protecting the cells from corrosion and micro-cracks. This construction helps the panels better withstand temperature swings, wind, and precipitation, maintaining stable performance throughout their service life.
