We continue to be impressed with Cochise’s solar array. From ten solar panels we are generating within spitting distance of 20 kWh. Twenty kWh is enough power to run the great room air conditioning during the middle of the day.
We are just beginning to understand how important this level of solar energy is to the efficiency and enjoyment of cruising.
And it’s fun seeing how well you are doing or have done, and comparing with other cruisers.
The 20kWh referred to in the photo above is generated by ten 340 watt panels. The layout of these panels is such that some of them are shaded at certain times of day. Our original estimate was that we’d see a 30% loss from rated output due to shading, angles, etc. This number seems to be right on.
During the midday sun, say 1000 to 1400 hours, output is averaging about 110 amps. We have seen as much as 150 amps on a momentary basis. The norm is 110/115 amps.
