Hey All,
As you will see, I’m new to this form and completely new to solar in general. I introduced myself, so excuse the repeat if you read the first post.
Firstry, id like to thank everyone who takes time to even read my posts, and to also ask for forgiveness upfront for probably silly/ignorant questions.
I generally pride myself in being able to do research on my own, but there seems to be so many factors invloved in a properly setup solar system that I cannot know for sure what it all means, so please keep that in-mind ?
OK, let me get started.
This is not my solar system, but my fathers. He has a house (Finca) in Mallorca, Spain. A few weeks after purchasing the house he did a complete upgrade of the solar system as the old one was, well, old and was a 3kWh system I believe. The new system is a 8kWh system and 90% of the items were replaced with new hardware (Batteries, PanEli’s, inverted etc etc), he spent around 23.000€ on this (And yes, he got multiple quotes before deciding on who to use and this one was actually in the mid range of quotes.)
The reason I’m actually posting this is due to me and my father believing the system seems strange (To us at least).
It can be a great day, 100% bright sun all day in summer and the sun setting after 9:30pm, systems shows 100% full etc etc.
Yet, after a few hours, the system shows at 98% or 95% (Which is great), but yet, the generator kicks in due to the Voltage being too low, under 23v or 24v (cannot recall to be honest) The generator lasts maybe 1-2 hours at a time.
Now to me, that’s confusing, especially due to the fact that the average consumption during the day and evening according to the reading on the monitor is +-400W, this powers basic things such as the fridge, computer, some lights etc. The water is heated via gas and has a pen lite battery starter, the oven and hob are both gas, no electricity connection what so ever, no kettle used, no toaster, nothing that had a big “drain” from what I can tell. And anything that does use lots of power is not connected at night (pool pump and borehole pump)
So my question, does this seem normal, shouldn’t the system be able to last longer on an average night? Also, whats the actual point of having a monitor system that shows %, but one can not really ever go below lets say 95% at nights? During the days if its overcast, but enough to generate some power one can see the system maybe show 75% or so, but don’t think we have ever seen it under that.
*Ive attached a few images I took of the setup (Internal elements) as Im not even sure how to best explain it all. The panels are in 2 locations (roof and garden), there are a total of 12 - 400W panels on the roof and 6 - 400W panels in the garden.
So thats a total of 4800W + 2400W = 7200W
= = = = = = = =
Really hope the above makes sense and that my thinking behind solar/how it should work is not completely silly.
Thanks in-advance! ?
