PV production longest day

[SteamyTea]

As PV is generally fitted to South facing roofs, at about 35⁰ angle. June 21 is not the best day just because it has the longest (or second longest) hours of daylight.

An E-S-W array would be impressive, especially if E and W elevations were angularly optimised.

That’s more or less my configuration.

The fence line is north south with the road being south.

Front elevation recessed 12 x325w all black at  30 degrees

Garage left (east) elevation recessed 6 x340w

Garage right elevation  recessed (west) 12 x 340w both  at 25 degrees.

The rear elevation are veluxes

I had room on the rear outrigger but decided 10.020 kWp was enough.

The DNO would  have allowed me upto 17kWp.

 

I am delighted with production and the system wakes up good and early.

In the words of our great leader, I tried to flatten the sombrero.

12 Months hence,

Not as good a day, but month to date way better than last year, annual similar.

My wish for a battery was fulfilled.

Waiting for solar edge smart water 5kW divert to arrive as immersun gave up the ghost in November.

Second battery SE dc coupled imminent.
