buy a new battery?
I've made my own panels from silicon solar cells,0.5 sq mt gives about 60-80 watts or 4 Amps max in bright sunshine -you need 18 volts + to charge a 12 volt battery.The smaller ones on ebay for about £20.00 do not do much,especially when behind a windscreen,and if it is coated are even worse.(do you have a/c)
You need to measure your current drain when static(put amps meter in line with batt +ve) then compare this figure with what the panel will produce remember your drain is for 24 hrs,and the panel is only producing in sunny weather.
Personally I would try and find what is draining your batt so quick,or if shot get a new one-My solar panels keep my spare batts topped up,but they are large panels

Sounds like you have a problem. Get that sorted first.
I can leave my V8 for weeks and it will start.
My last 300TDi was the same I could leave it at least a couple of weeks.

I've known even nearly new batteries to fail due to the electrolyte being to be low in one cell, hopefully you have a battery that that can be checked.
I always gone for a replacement battery with cell caps so I can check the electrolyte level and topup as required but last year I had to replace my battery after 9 years so what did I get .. for the first time a fully sealed one, it's full sealed unless I start digging around with a screwdriver. So we will see how long that lasts.
Anyway my disco was parked up for 4 weeks with this new battery fitted and started ok just the same as it does parked up over night
