Glue on your tail boom and never charge your battery again.

I would not do this. The temperature that will be generated under the panel is going to be very high, potentially weakening the structure. Those who glued flexible panels on top of their RVs know what I am talking about. I have seen melted flexible panels.

This panel would be too large to put on a tail boom anyway (despite the quoted dimensions of 46x21mm!). They also imply that you can't bend this thing in an extreme way. On the other hand, the $/W is very good if you can use it in some non-aviation application.

At 21" x 46" x 0.125", it's too big and probably too heavy. We need
smaller panels to replace the no-longer-available STrobls.

Why bother with solar panels when you can buy light weight lithium batteries with enough juice for anything you can imagine? Solar panels are from age of lead batteries.

Not exactly. I know a guy who has a radio, transponder, Butterfly vario, LX9070, S80, Flarm, V3 vario and a strobe built into the vertical fin, that can either act as a strobe or only strobe with a Flarm alert. All that stuff takes about four hours to go through one lithium battery with two factory installed solar panels topping up the battery. Good thing he has two and possibly three batteries (if he is not going to use the engine).

Because you might have an engine in the back, and need all that lead in the nose?

Besides effectively increasing battery capacity, they are very useful for recharging the batteries between flights. We are continuing to add electronic devices (transponders, flarm, foot warmers, etc.) while on-board battery capacity is stagnant. In some gliders, like the DG80x, battery capacity is already at a critical level (and lithiums are not an option). If I ordered a new glider I would definitely go with the solar option (assuming it is available with Strobls closing).

Same problems with the DG400. If anyone has worked out an elegant solution to add separate instrument batteries, please reply privately to
