Hello everyone,
My name is Cédric, I live in the suburbs of Paris, France (aka the sticks). So about ten years ago I bought this plot of land and, with my wife, we built a house on it (no kits, just DIY home building, we did everything on it).
At the start of the construction I had decided to put solar panels on the roof at some point in time (when I had the money & courage to do so). We decided to build a 100% electrical house, no gas, no wood, so as to later exploit the PV system to it's fullest.
From an insulation standpoint, to make it live-able (heating, lighting, ...), it consumes around 37kWh/m2/year, the entire electrical bill (with an EV car) is at 60kWh/m2/year - prior to the installation of PV panels.
I put a south roof at 35°, beyond I didn't see myself climbing on it actually, made it ready for PV (ie attachments etc).
So, fast forward several years, I've put, for now, 12 panels @ 365Wp with associated enphase micro-converters and it's running fine. I put load sharing systems coupled to an astro controller to heat water in the day (for example). I put micro-converters because I have very old oak trees in the garden that cast some shade over the roof during the day and there was no way in hell that I was going to cut those trees down. They do get trimmed to stay in shape by a pro every two years but it's only trimming of dead wood; they're too high for my taste ... I'm not suicidal, getting on a roof is one thing, going to the top of 30 meter oak tree is another, it's a long fall ...
I'm now getting ready to add batteries to the system (and add solar panels to go with) but, given that my core driver was to reduce my carbon footprint, I don't want to buy new batteries, rather I want recycle older batteries no longer fit for purpose (for example a Tesla battery from scrap yard).
So I've come here to benefit from your collective experience to figure out a way to solve my issue of getting a HESS based on second life batteries whilst remaining compliant to french electrical regulations.
Thank you for welcoming me amongst you,
Cedric
ps: For those who are wondering, Fluffy is a nickname that my US Corvette friends have given me a while back and it stuck. Yes, I do have a Corvette, as such I my carbon neutral objective is going to be more challenging to meet
