Yes, the hunting camera comes with a solar panel with a 3m cable, the solar panel can be adjusted to suit the location and How do you get the electricity? How much capacity does the hunting camera have The product itself has a battery capacity of 7800mAh and is powered by the solar panel. Please fully charge it with the adaptor before use. You do not need to remove it often to charge it in summer and in sunny places 

Yes, but you need to contact us to purchase the bracket and extension cable separately, the extension cable is 2M 

I think they went with common adapter sizes based on popular lens types, you can get a set of step up/down rings that can be adapted to your 55mm filter diameter. I think they sell for like $15 or something like that. You're going to want to get a 55mm step up to 58 mm ring 

i very much doubt it... it's worth risking your sensor and or your eyes... 

No don't use this for that purpose. Use a properly designated "Solar filter"
