First trials

The first few days of use have been satisfactory.
The solar panels are mounted flat on the deck of the roof.
Perfect delivery.

Flexible solar panels

I installed and am using two panels. So far, everything's fine. This winter, the performance is a bit low. We'll see when the weather gets warmer! But they seem to work well. I bought them for their reliability.

Nickel charges my battery well

Smooth and Tough

As I have had a Sunbeam Solar panel on my boat for a few years and it is still functioning well, I have now standardised all of the panels to this make.
They do not have a junction box mounted on the face of the panel, it is built into the rear of it and that is far better than the face mounted junction boxes as they are the usual point of failure on a solar panel.

Solar panels

Fast and professional support in implementing tax exemption for solar systems on yachts.
The solar panel is used as a replacement on our N 360 for the one installed in 2001. Even if the power of the panel seems very small at 37 watts, it is a good support for maintaining the battery charge while lying down. While sailing, the consumption of the navigation instruments is compensated.

I installed 2 T30F panels (glued to the deck) last week. Very satisfied at the moment. Production of approximately 2A between the 2 panels (the backstay provides some shade).

Too early!

Delivery and product compliant, however I cannot rate this panel until it is installed.

Good, but a technical flaw

Looks good, is light and has good properties - enough straw for the surface. However, a problem could possibly arise - the cable exit is a few millimeters high and at the edge - there is an unevenness. Since the panel is thin and soft, there is a risk that it will be damaged if someone steps on it. There is also a gap at the edge that I tried to fill with the silicone, but I am not sure whether I have made enough of it to prevent flexion - difficult to assess. I hate silicone ..

The solar panel works well. There is only a small voltage drop between full sunlight and shade, which is good. The description should have stated that it is a plastic back and the connecting cables are also on the back.
