@sleepy62 @tojiro it sounds lovely and I’m considering a similar project One thing I’ve been struggling with, is estimating how much battery storage would likely help, and what capacity to go for (I’ve been told to aim for twice the daily production capacity) My electric bill is predominantly the heat pump in the cold months, and I know the batteries are next to useless there

@GuillaumeRossolini @tojiro This really depends on where you live. Our local hydro utility gives us one for one with net metering so we effectively use hydro as our battery. Others may offer time of day usage deal whereby they charge more for early evening usage, so a modest battery to get you through the supper hour makes sense. You will need to check with the local utilities and see what is practical.

@GuillaumeRossolini I most wanted to be fossil independent, & always overbuild, so have a 24kWh battery. I don't use much (one person), so this could cover 2-3 days use. Longer if essentials only. My EV has V2L, so it could help out, and my panels keep working, grid available or not. On a sunny summer's day I could easily fill triple that. 🤷 @sleepy62 @tojiro
