May 2024 generation

[AlBargey]

May:

Solar: 462 kWh
Consumption: 380 kWh

System Efficiency: 82%

Battery Efficiency to Date: Discharged 1,322 kWh / Charged 1,376 kWh = 96%



Last Month (April):

Solar: 680 kWh
Consumption: 577kWh

System efficiency: 85%

A very different month compared to 2023, over 200kWh down vs 12 months ago. It was poor enough that grid charging was needed on one occasion.
Best day was 29.55kWh (31.29kWh in 2023) - PV still covered over 94% of consumption though, so I can't really complain.

May 2024 was poor compared to 2023 at my company array - managed 1.469MWh in 2023, vs 1.216MWh this year.

Production - 1.216MWh
Self consumption - 760kWh (62%)
Export - 460kWh (38%)

Total Consumption - 2.98MWh
Import - 2.22MWh (75%)
Self consumption 760kWh (25%)

I found some interesting data from the Met Office with a long history of bright sunshine hours for different regions of the country.

On downloading the data for England-Midlands, and after analysing it becomes obvious why our solar panel generation is so variable from 1 year to the next.

May 2024 only achieved 82% of the average from the last 20 complete years.

Unlike the very sunny May 2020 during the 1st covid lockdown which achieved 150%. If only I had solar panels installed then.
Instead I get Dec 2023 at only 52% of average.

Similar to others, May was a long way down from last year and below PVGIS

Sunsynk system - 574kWh vs 625kWh PVGIS and 730kWh last year
Hoymiles man cave system - 131kWh
