New to DIY solar – sanity check on my output figures? (Ecoflow Stream + 3x 460W panels)
Hi all, very new to this so please bear with me! I'd love some insights and a bit of education on what I'm seeing with my modest setup.
I have 3 x 460W panels on my garage roof – two facing east and one facing west. The two east-facing panels are linked in parallel into the PV1 input on my Ecoflow Stream microinverter, and the west-facing panel goes straight into PV2.
During this recent run of good weather in the UK, I've noticed PV1 (the two parallel panels) is maxing out at around 392W. No shading on any of the panels and we've had clear skies for the last couple of days.
I know the 460W rating is measured under ideal lab conditions (STC) and real-world output will always be lower, but I was expecting two panels in parallel to push a bit higher than 392W between them. That works out to roughly 196W per panel, which feels low even accounting for real-world losses.
Can anyone sanity check this for me? Is there something in my setup I might be missing that could improve output, or are these figures actually realistic given the panel orientation, UK conditions, and the Ecoflow Stream's input limits?
Appreciate any help – this community has been a great resource while I've been getting started!
