## Questions & Answers

**Q: Is it waterproof? Can it be exposed outside for long periods?**
A: Yes,our solar battery chargerv 12volt 20W is waterproof.

**Q: Is there a suction mounted version of this panel so I can stick it to the inside of my Campervan windscreen? Would it still work sitting on dashboard?**
A: As fr s I know, there isn't a sucker mount option, just the hook eyelets and magnetic mounts. I have however placed this on the dashboard of my van and positioned it under a roof skylight with good results. Just make sure you park facing south to maximise the sunlight it gets.

**Q: does this have to be disconnected before starting and using the vehicle? Thanks, Alan**
A: Dear,
We recommend that you disconnect before starting and the vehicle. The car will encounter uneven roads while driving, and the connection may be loose.

**Q: Can I leave it attached to a 12v battery I use for a pond pump. I want to keep the battery working constantly for periods of time.**
A: Yes you can, if the battery capacity is full the regulator that comes with the panel will cut off, it will probably say in the paperwork what ah ( ampere hours ) the panel charges at ie 10ah  so if the battery is 70A it will take 7 hrs to fully recharge.
