Solar PV Performance Thread - Post your monthly output

championc

I think it would be very useful to post Solar PV monthly generation figures. Not only could it highlight a problem further down the road, but there many be many owners who are getting far less than they expected (or promised by an installer) and would welcome feedback from other owners.

Of course, there are so many factors involved. Your location in the country (or abroad for our international boardies), your array size, your array direction and the panels mounting angle.

No, it would be a constant alright. See my calculations to back that up.

It's a bit like heating your water with the immersion, it would be on full blast until you either switch it off, or it reaches the set temp. You are probably thinking of an oven, that kicks in for a while and then switches off for a while.

800l capacity, the water is coming in at about 10C and you want to heat it to about 40C?

This uses 4.2 * 800 * (40-10) / 3600 = 28kWh or a bit over €2 on the night rate (this is roughly consistent with your assertion it would take about 15 hours at 2C per hour, so 15 * 2.2 = 33kWh)

Not that bad really, where do I get one? :pac:

it was in ALDI, 395 euro absolute fantastic to sit in the back garden, kids happy, 37 toastie, in lockdown....

and it absolute kills any export

the inflatable aspect of it creats good insulation.

I could have been off the grid if I had bigger batteries. With lack of movement the cars are not getting recharged so that means my business case for not buying the Eddi looks poor
