Solar Solar Solar.
The amorphous panels went on a well know web sales site and a couple of Yingli 220 Watt panels from Navitron were bolted on instead. So that is 440 Watts total now which has made a big difference.
I bought another two second-hand Yingli panels from Bimble Solar and put them flat on the wheelhouse roof. They were fine in summer but lost the sun rather quickly as soon as we saw the autumn equinox. So I reinforced the trackable mount and bolted the two extra panels on the sides of the original two. I will post a photo as soon as the sun comes out again and the wind drops. That now gives up 880 Watts which is a really useful amount of power. On a fine sunny day that will give use 33 odd amps and regularly hits 20 amps on sunny days in November.
I found a good deal from Bimble Solar on there meters and the MPPT charge controllers by EPSolar, their Tracker range..
A deal was had for a 600 Victron battery monitor which replaced the simple Volt meter for the domestic battery bank. It provides a fantastic range of information and has set up for alarms and external switches.
An hydraulic lowering system is being thought about at the moment. I feel it would be prudent to lower the PV array when the barge goes out.
For the same area of panels it is now possible to get 1300+ Watts and I am sure they will improve all the time so it would be a simple job to uprate the system.
