Hey Power Forum community,

If you're anything like me, you're always on the lookout for solar tech that punches above its weight – literally. Today, I'm thrilled to introduce the latest from Red Solar (Hunan Red Solar New Energy Science and Technology Co., Ltd.), a leader in high-efficiency PV modules. Their Ultra-Light TOPCon series is here to revolutionize installations, especially in SA where roof loads, transport costs, and harsh weather can make or break a project.

These panels combine cutting-edge N-type TOPCon technology (Tunnel Oxide Passivated Contact) with ultra-thin glass for unbeatable lightness without skimping on power or durability. We're talking G12R rectangular cells for the 450W model and M10 cells for the beefier 595W – both delivering top-tier bifacial potential and low degradation for long-term gains.

Why Go Ultra-Light? The Game-Changing Advantages:

• Featherweight Design for Easy Handling: At just 9.8kg (450W) or 21.2kg (595W), these are up to 50% lighter than standard panels. Perfect for DIY installs, retrofits on weaker structures, or remote SA sites where heavy lifting is a hassle. Less weight means lower shipping costs and faster setup – high returns from day one!

• Superior Performance in Tough Conditions: Rated for 5400Pa front / 2400Pa rear load (snow, wind, hail – think Joburg storms or Cape gales). Anti-PID guarantee and suitability for harsh environments ensure reliability. Plus, low temp coefficients (-0.30%/°C Pmax) keep output steady in our variable climate.

• Max Efficiency & Yield: Up to 23.03% efficiency means more kWh per square meter. First-year degradation ≤1%, then just 0.45%/year – backed by a rock-solid 12-year product warranty and 25-year linear power warranty. That's industry-leading longevity for maximum ROI.

• Eco-Friendly & Versatile: Ultra-white AR-coated glass boosts light capture, while customizable cables and IP68 junction boxes make them plug-and-play with MC4 connectors. Ideal for residential roofs, commercial arrays, or off-grid adventures.

• Proven Quality: Certifications like ISO, CE, and Clean Energy PV Cycle mean peace of mind. And with power tolerance of 0~+5W, you're getting consistent output every time.

These beauties are designed for high-yield setups, whether you're scaling a home system or going big on a farm. Imagine slashing install time by 30% while boosting energy harvest – that's the ultra-light edge.

Important Note on Availability: These panels are only available on container-sized orders. For inquiries, quotes, or to discuss bulk shipping to SA, contact [email protected]  or Wimpie on +27 67 189 7084 (WhatsApp only). Let's get your project powered up!

These sound awesome - any intent to sell them to end users via the PF store?

So, can I use these panels on a 5kW Sunsynk, which states 13A input?

Considering that they are selling them only in container-sized orders, probably not.

But more than that, the specs of the 450W Ultra-Light panel are wrong (CETC-435-450TR(L)/96). According to the table above, at STC the Voc=37.2V and Isc=14.3A. But if you look at the spec sheet, it's Voc=35.76V and Isc=15.66A at STC. Maybe @Powerforum Store can check and confirm.

Personal 2c worth. Vmp=14.76A at STC. Basically, you won't destroy anything, but you won't get the peak power out of the panels in summer, you'd clip at around 90% of what the panel can achieve. I'd rather go for the 590W panel out of these two options, if it's for a 5kW Sunsynk. Or otherwise if you want the 450W panel, rather go for a different inverter like the Solis that takes a higher MPPT input current.

Currently its only Container orders however we are working on getting some Bonded and Consignment stock available this will be then available to PF users and for that matter anyone that wants these panels.

The 595 Watt falls within the safe margin for Sunsynk working amps is 13.65 slightly above but not excessive.

The Data Sheet is accurate the Original post should have highlighted the range instead of a specific voltage however according to the data Sheet the 450 watt Ultra light panel VOC is 35.76 V and Short circuit current is 15.43 Amp

I would also Recommend the 595 Watt the amperage on these are more suited for the Sunsynk.

Thank you for the info.

Thank you for the feedback. Now to see if they will become available for smaller scale purchasing.
