Solar panels keep exploding!

i don't think heat shields can protect certain parts under certain circumstances...unless they fixed that in the update

So it's a custom system! Maybe the recent 1.0.40 update broke the system.

@Toinkove im playing on the Juno System texture Redux, but why should panels explode around droo? nothing should have been changed when the textures were?

Where exactly are you! I’ve only had this happen around Sergeea. Solar panels have lower tolerance than most parts, I think only like 500° C (maybe it’s 1000 and other parts are 1500). The only work around to really fix this is change the heat tolerance in the tinker panel. To some extent parts will just eventually get destroyed if you fly too close to a star but there should be a way to make panels resistant for inner planet missions as we’ve actually done it so.

Your other alternative I guess would be an RTG
