In response to customer feedback, we introduced the larger 120W FLEX-120 flexible solar panels. The FLEX-120 is based on our leading 100W flexible panel, with the addition of 12 extra solar cells. We were asked for a longer, thinner panel, so the FLEX-120 is only 540mm wide and only 1365mm long - ideal for fitting to narrowboats and modern RV's. Read about the flexible panels installed on 'Narrowboat Charlotte II' in our case study section.

Unlike other flexible solar panels, our FLEX range uses the same monocrystalline solar cells as our professional grade rigid solar panels. This means that, in addition to being flexible up to 30-degrees, the FLEX-120 is still the most efficient panel on the market, with the smallest surface area per watt. By using a unique, 5-layer bonding process, the FLEX-120 is a flexible solar panel that is only 3mm thick and weighs only 19-grams per watt. This new panel can be fitted almost anywhere.

At 21.5% efficiency, the solar cells in the FLEX range are the most efficient in the world, meaning that you get the most power from the smallest amount of space. In fact, they are up to 50% smaller than other solar panels. Made even more effective by the patented back-contact design, these panels give you more power in lower light conditions throughout the year than standard products. For quick and easy connection, we recommend our 5m ‘clever-clip’ solar cable set.

To maintain the shape and not have to cut the solar cells, the FLEX-120 has a slightly higher voltage that the 100W version (22.0V). Therefore, to optimise the charging current, we recommend the use of an MPPT controller, such as the Victron BlueSolar 75/15.

Flexible monocrystalline panels carry a full 2-year product warranty (1-year in marine / salt-water environments) and a 10-year 'power output' warranty (to >90% original output).

Perfect for narrowboats, yachts. motorhomes and much more, FLEX panels are the future of solar!
