Sundsholm 420 Wp Glass-Glass – For those who want certainty, every single day
When you choose solar panels, you’re really choosing peace of mind. The assurance that your system will still perform tomorrow, in five years, and even in thirty years exactly as it does today. The Sundsholm 420 Wp glass-glass solar panel is made for people who look at their investment this way: thoughtful, future-oriented and without compromise.
This panel brings together an exceptionally strong glass-glass construction, a powerful 420 Wp output, 108 perfectly protected cells, and bifacial performance that quietly boosts your energy yield. Its compact size (1722 × 1134 × 30 mm) and solid 21.5 kg weight say one thing clearly: this is a panel built to last.
Built to keep performing
Thanks to its dual layers of glass, the cells are completely enclosed and protected from moisture, temperature fluctuations and microcracks. Intense sunlight, hail, harsh winters, scorching summers — this panel continues to deliver stable performance, year after year.
And you feel that in the warranties. Sundsholm offers, without hesitation:
25-year product warranty
30-year linear performance warranty
These warranties inspire confidence. They come from a manufacturer who knows their product is built to last. And as a customer, that’s exactly what you want.
More yield, with zero extra effort
Because the panel is bifacial, it also generates energy from the rear side. Install it above a bright or reflective surface and you immediately gain additional free production — without using a single extra square centimeter of roof space.
It’s the simplest way to get “more energy from the same surface.”
Also perfect for motorhomes and campers
Sundsholm has a particular strength that shines in motorhomes: stability and vibration resistance.
The glass-glass structure makes this panel far more robust than traditional modules. On the road, a solar panel must endure constant vibrations, wind pressure and rapid temperature changes. Where standard panels may develop microcracks over time, the cells inside this glass-glass panel remain safely encapsulated and protected.
This makes it ideal not only for homes, but also for:
• motorhomes that travel long distances
• van conversions with limited roof space
• campers aiming for maximum autonomy
• travellers who depend on stable solar output during their trips
The bifacial effect provides an extra bonus on camper roofs: many have light or reflective surfaces, allowing more light to reach the rear side — and therefore generating more power. A quiet, reliable energy source that follows you anywhere in the world.
A panel that rewards you every single day
Install this panel on your roof and you’ll feel more than the financial benefits. You’ll feel the satisfaction of having chosen true quality. A panel built to withstand life itself — rain, wind, heat, cold, long drives through France, Spanish summer sun, and the harsh autumns of Belgium.
Sundsholm doesn’t give you a standard panel.
Sundsholm gives you a panel that will let you forget, for the next 30 years, that you ever had to make a choice in the first place.
