[Sticky] Solar Power Output – Let’s Compare Generation Figures
Toodles, heats his home with cold draughts and cooks food with magnets.
@toodles what a great month for solar! I love April as this is where my shading is gone completely. 1020KW
Beat last year's production, which was the best for April till now.
16kw Samsung TDM ASHP. 8.4kw PV, power optimizers 20×420watt panels 6kw SolarEdge inverter.
When the clouds are gone and the leaves aren’t out it’s good. I was loosing 30% to clipping due to export limit at the back end of the month, just couldn’t find enough things to run to soak up the power. As soon as there’s a cheap V2G EV available with a decent capacity I’m in.
@papahuhu I have Enphase IQ7a microinverters on each of the 21 panels and at maximum production, they will clip by a few watts but I see peaks of ~7.1 kW. My G99 allows for 10 kW export but I rarely see more than ~7 kW and then those peaks are only for a few seconds at a time. With the current arbitrage on Cosy and Outgoing tariffs being less favourable than of yore, I only export that which I cannot consume locally now. The last call upon the grid for import was on the 19th. April and I am exporting ~15 - 25 kWh per day now. The Daikin heat pump is zzzzz’ing now and the Sunamp Thermino heat battery consumes ~3.0 - 4.5 kWh per day, we are an all electric home but the Air Fryer and the Induction Hob do not impose huge loads on the system. The Tumble Dryer is a heat pump model so the main energy eaters are the washing machine and the dishwasher I think. Of course, the main need for those multiple kWh’s is during winter when the solar panels are ‘resting’! I dread to think what we will be paying per kWh by then!!!☹️ Regards, Toodles.

On the contrary, I am happy to report that we have had a rainy April and thus a lower yield this year! Water reserves are on the rise and this is what we need in view of the upcoming summer.
I must admit however that having 9 degrees today (1st of May) is rather odd….Apparently we are experiencing a cold wave and I expect our ASHP to kick in this evening (it has not switched on as scheduled during the last few days, with OATs reaching mid 20’s during the day and IAT constantly above 20)
@toodles The Scrooge in me is anxious over the winter too. Catch 22 is that I either fix for 12 mths now on a heat pump tariff at about 15p or wait in vain for a VPP to emerge from the chaos to make some profit. Mr Greedy is in conflict with Ebenezer, a lot depends on whether Millibands energy market measures work or not. The cynic in me expects the consumer to continue to be screwed over marginal pricing.
@mk4 Must be that global cooling! I still vividly remember a documentary in the late 70s warning that the data indicates a new ice age is on its way. I recall it was Mr Spock narrating it, with London and NewYork under an ice sheet.
One day someone will tell the truth in that we only superficially understand our climate, and it is way too complex for our stone age climate models to predict. But I’m still good with burning less stuff, cleaner air and water is a massive benefit to humanity.
@papahuhu I hope to have a few months ‘grace’ over the summer before having to commit to any new tariff / renewal / contract or VPP package. It is not just that I shouldn’t have to pay anything BEYOND THE EXTORTIONATE DAILY STANDING CHARGE but I hope some common sense might prevail meanwhile. I’m not sure that I’m convinced there is much chance of this happening though. Regrets, Toodles.

@papahuhu Perhaps we should all be listening to Mr. Orangeman as it would appear (so he tells us) he knows all there is to know and that ’Drill Baby, Drill’ is just one of his commandments. We are all mere ignorant sceptics it would seem, anyway, who needs all those ‘windmills’?! Regrets, Toodles.

@toodles Im trying me best to ignore orangeman, I figure that is the most constructive and effective resistance. I had another look at one for the garden, even a 1kW unit at 10m would be a help. I spoke to planning last week but they told me once you have a heat pump even the smallest wind turbine requires planning approval. The irony is that the heat pump is the reason I need a wind turbine.
