Renewables: "talking 'bout my generation"

Heat is hitting generation hard here, but still scoring Hawaii's each day, so excellent results, with month end projection now at 107%.

Yes, on my array installed a year ago, 3.645kWp on a 3kW inverter, this week is the first time ever I've not experienced any clipping in the middle of a clear sunny day (no flat top on my otherwise perfect solar production curve). Probably a combination of a lot hotter weather than we normally experience (30C plus whereas low 20's is more normal for us), and the panels are dusty as we've had no heavy rain for a while (we live in a relatively dusty location)

A Maiden.73 today.

Lower irradiance/UV levels, combined with temperatures of over 30 degrees (peaked at 34 degrees) conspired to reduce efficiency and output.

5.65 Os today, slightly better than yesterday

‘Just’ in Heaven 2nd day in a row (had 2 consecutive Heavens in June as well -  happy with that)

7.003 O’s

Maidens over, just an Hawaii today!

Cool and overcast on the E. coast til lunch then Sunshine. 

Hawaii + 0.075 O’s

15.4 kWh, 5.66 Os - a solid Hawai'i but too hot for a Maiden!

Also, for most of the day the local mains voltage was between 245-250 volts. Still in tolerance but high enough that the Growatt inverter on my toy array (which over-reads the grid by a few volts) disconnected. Missed out on 2-3 black-market kWh there ...

6.00 Os today, that'll do nicely

Near perfect curve for Friday.

Maiden + 0.25 O's

Not as good on Saturday.

Hawaii + 0.84 O's

Peak on both days was below 3 kWp due to the heat, or lack of cooling wind. Spent both days away so missed the benefit of decent generation. 

Production now around 2 days ahead of PVGIS.

My new (additional) array is now installed, taking us to a total of 7.2kWp south facing.

6.3 O's yesterday on the first full day of data.

My generation is a little down on where I'd expect - I'm guessing this is due to a combination of very high temps (we normally only see low 20's here) and dry dusty conditions with no rain to clean the (old) panels. Generation is now 4 times average daily usage in summer.
