Pictured yesterday...

Yesterday was a perfect cloudless day, - giving near maximum photo-voltaic output (19.54 kWh) on top of maximum hydro output (20.92 kWh) : total 40.47 kWh.  This concurrence of maximum outputs only happens at this time of year when water flow is still good and the sun sufficiently high in the sky to make the pv panels give close to their full rated output.  It also helps that the air is still cool, which boosts the output from the pv panels.  

For those discerning enough to note it, the asymmetrical shape of the solar output curve is because the orientation of the panels is ESE, - and they are located in the northern hemisphere.
