Some people know how I feel about large scale wind farms; and Photovoltaic Cells; for use in the UK (hint it’s a good way of requiring more Gas Turbines to be built). However when living off the Off The Grid, are they any use?

On my recent walk along Regents Canal I saw these two boats:

NB Florens with both a Wind Turbine and Photo Voltaic Cells (The Wind Turbine was spinning much faster then the photo shows).

This boat, has Photo Voltaic Cells on its roof, on a wooden frame holding them at about 40 Degrees.

Anjuna has a frame that looks like it came as part of the cells.

Lots of boats seem to back up generator or shore supply with “Renewables” So I am wondering just how effective these are in this context.

When I get some time to play; I will conduct an experiment.
