The dark red line is February. I've included December (being the lowest month for solar generation) by way of comparison. Having the winter solstice bang in the middle, it is completely flat to all intents and purposes. February shows a clear trend of the graph climbing towards the end of the month. I was quite surprised how quickly the generation has picked up as we make our way out of winter, topping 8.5kWh for the one day 27th February.
Here it is on the yearly forecast chart:
As you can see, February's generation has exceeded the forecast amount (by 13.54 kWh). This is 16% higher than the forecast. Quite reassuring given the poor show by December and January.
To catch up on the deficit from winter's generation, March-August will need to outperform the forecast by 3.5% to achieve the total forecast value for the year of 1645kWh.
Here is a graph to show the 'value' of daylight during each month. It shows how much electricity (on average) is generated for every hour of daylight of the month (from sun up to sun down each day). Note, being an hourly value, this is not affected by the varying amounts of daylight each month - it's a kind of "sun strength" for the month, taking into account the maximum height the sun reaches in the sky, and the average cloud cover.
If the sun was at full summer height all day, and there was never any cloud cover, this graph would show the theoretical maximum of the array, which is 2 kWh per hour (or 2 kW as it should be called!) At a smidge over 0.1 kW during December, the array is only producing 5% of its theoretical maximum. I am curious to see how high it will get over the summer months.
I've also submitted our Feed-in meter reading for the winter quarter (Dec-Feb) so I'll post again later in the month with a finances update.
