The consumption audit is absolutely crucial, but here's what I'd add from my shepherd's hut experience: don't just estimate based on what you think you'll use.

Spot on observations from @VoltAlison and @PennineNomad. Your facilities background is genuinely valuable—understanding how systems fail and what happens when demand spikes is half the battle with...

The structural side is critical — I learned this the hard way with my shepherds hut build. Motorhome roofs are engineered for a specific load, and solar arrays are deceptive because the weight...

Spot on about the matching bit. I learned this the hard way with my shepherd's hut setup — tried pairing two different capacity LiFePO4s and the BMS went mental.

Planning to upgrade to LiFePO4 for my shepherd's hut build and I'm a bit worried about winter performance.

Spot on about the shadow mapping — I'd say that's non-negotiable. But before you even think about panel angles, nail down your actual energy needs.

What @DodgyRoamer's getting at chimes with my experience moving into the shepherds hut three years back.

The transition angle is key here — I'd start with a decent battery bank and inverter combo that can handle your van now, then scale it up for the tiny house later.

Microhydro's a solid move, @Renogy_Nerd. I've got a tiny Pelton wheel setup powering my cabin and it's genuinely the most reliable generation I've got — runs 24/7 unlike solar, and even modest...
