A great file with so much very useful information again. You have saved me hours of measurements and calculations.
We now have our new davits & solar frame from Riza and will be installing these soon with 2 x 260w 48v solar panels so this information is very helpful indeed.
One question... I see you recorded your power usage in 2008. Did you have LED lights all round at that time or were they all the original bulbs? I think this would make a significant difference to the night usage if this was based on non-LED fittings.
