If you've regularly got the starter to the level you need a jump start you'll be damaging the plates in it, especially damaging in a starter type battery as it needs a large set of tightly packed plates to generate the Cold Cranking Amps.
A tracker and dash cam even in parking mode is probably drawing about 0.5 amp so will use 12Ah of capacity every day. With a minimal 75Ah starter you'll be at the 50% recharge needed level in about 3 days.
If you need to replace that with solar assuming 8 hours of good light you'll need 1.5 to 2 amps of charging current, so average 25-30 watts for those 8 hours.
