20. Solar farm

The solar panels have been installed on steel posts on the north-facing bank. We have a 5kw system, which should mean our electricity account is close to $0 (or we may even earn a profit). We are charged 19.4c per kw that we draw from the grid, and get paid 44c per kw that we feed back to the grid (surplus to what we use). It isn't hooked up yet, but should be within a couple of weeks - then we can start generating!
