lightweight, compact and extremely powerful

The solar panels of the series-20 are light, very compact and extremly powerful. The monocrystalline PERC high-performance solar cells are protected in an EVA laminate and ETFE coatings against weathering. Even in diffused light conditions or even in winter, the modules produce a high charging current.

The solar panels of the series-20 have a front-side cable outlet, panel backside is completely flat. The right of the cable terminal there is a possibility to stick through the cable.

All solar panels have more cells than normal panels have. The additional 4 cells gives the panel a higher voltage and ensure that also by flat installations on deck in hot regions the panels charge the batteries extremely powerfull.

All solar panels can be screwed, glued or attached with clips. The cable has a length of 3m. The carrier material is an aluminum sandwich core. By the core material the cells are perfectly supported and protected. The solar panel adapts to curved surfaces, with maximum curvature of 3cm/m panel length.

Inside the panel package there are white screw rosettes for countersunk screws. It prevents damages of the panels laminate by the screw head.

The solar panels are designed for the harsh marine and salt water use. The cable outlet is screwed to the mounting plate, completely sealed and 100% saltwater proof. By hermetic encapsulation cells and carrier plate are themselves well protected against the aggressive saltwater. The solar panel sizes are optimized to an absolute minimum. The distances between the cells and the panel edges are important for isolation reasons.

Please note that the power output of solar panels depends directly from the light intensity - not heat - and has seasonally strong fluctuations. For optimal performance, the module should be oriented as possible perpendicular to the sun and partial shade should be avoided.


What is the total thickness of the panel, not including the electrical connection?

The total thckness of the panels series-20 and series-40 is 5mm.

Why are SunWare panels not more flexible?

Solar cells needs a more or less rigid structure in the back to prevent cracks. Solar cells could easily broken by lokal forces. In the section "Solar panels videos" we have a video which shows how easy you could brake solar cells.

Installation types

The panels of Series 40 can be screwed or glued. The back of the panels is pre-treated in such a way that they can be glued with 1-component polyurethane glue (eg Sikaflex). For the screw fastening, there are circumferential holes in the carrier plate. The laminate has to be drilled at the points, srew roserosettes are includes in the package.


SunWare Series-20

At the BOOT 2016 exhibition in Düsseldorf SunWare presented the series 20 and 40 to the public.
Available in 9 different sizes, from 14 Wp up to 100 Wp.

Open-circuit voltage and short-circuit current measurement

The video shows you how you could check the function of a solar panel by measure the open-circuit voltage and short-circuit current (Uoc, Isc).
