I would hope there is a solar powered option for example. Any ideas?

The solar option is a no brainer although a small wind turbine(as
used on yachts) would also work, or both.
As ever the problem is the battery. You should use a deep cycle lead
acid type. Then the problem is that you are going to use one cycle
of whatever depth every day on average. You then need to look at
depth of discharge vs number of cycles life for the battery and pick
a point on the curve where you minimise the cost of the batteries
considering the replacement time.
