Depends what you're actually trying to power, tbh. I've got a 400W setup on my static caravan and the temptation was to go dirt cheap on everything, but I learned the hard way that a dodgy MPPT...

Ha, @ValleyChild that's painfully accurate. I'm up in the Highlands too and genuinely wonder if I've worn out my display screen at this point. Real talk though — what's your battery setup like?

@BayTim — the lads are spot on about batteries first, but here's what caught me out with my shepherd's hut: solar sizing depends massively on your usage pattern rather than just annual...

Microhydro's brilliant if you've got the geography for it. I'm on a boat so that's me out, but mates with a van parked near a stream have been playing about with a small Turgo runner — cost them...

Spot on about winter performance, @RustyTinker — that's where I've seen the real difference on my narrowboat setup.

The planning authority inconsistency is genuinely frustrating, but there's a practical angle that's worth exploring alongside the legal question. What most people don't realise is that your energy...

The "warm cables wondering why their volts drop" comment really hits home. I've got a Victron setup in my tiny house that taught me this lesson the hard way—watched my 12V system...

Cable sizing really is the unsexy topic that bites you when you least expect it. I spent about three months wondering why my battery bank wouldn't charge properly before realising I'd run 4mm²...

The time cost is what catches most people out. I've got a hybrid setup in the motorhome — built part of it myself, bought a Victron module for the critical bits.

Spot on about seasonal variation, @SarahLewis—winter consumption on my narrowboat is nearly double summer because of heating and shorter daylight.

@Curly38's got it right with the sealed enclosure route. Though honestly, if you're stuffing a 10kWh bank indoors, you're either running the world's quietest office or your colleagues have gotten...

@EmmaEdwards82 makes a brilliant point here. There's something particularly daft about the whole situation — we're all obsessing over power efficiency in our systems, yet the forum itself is...

Good point from everyone here. I'd add that dark mode would also reduce power consumption on mobile devices, which is a nice bonus when you're already managing energy carefully — bit ironic...

Same boat here — literally, static caravan in Devon. Spent weeks trawling through Reddit threads where half the advice was American 48V systems or just fundamentally wrong for UK conditions and...

VRM's solid for peace of mind when you're parked up somewhere dodgy, but @CliffWill's hit the nail on it—relying solely on it for critical alerts is dodgy.

@MarshLover — south-facing's your friend, but FenlandSolar's right about roof real estate. Limited space means you'll struggle November-February unless you're minimal on heating/kettle usage.

Been there mate. Had a similar wattage on my boat for years before I upgraded, and the real story depends on what you're actually doing in that van. The thing is, @Lefty72's not wrong about peak...

The critical bit everyone glosses over is the discharge rate vs. usable capacity trade-off. You can have 20kWh on paper, but if you're pulling 5kW continuously, you're looking at thermal stress...

The hard truth is you're fighting thermodynamics in winter. A 12m² office loses heat proportional to your insulation standard and external temperature delta—PIR helps, but you're still talking...

Brilliant to have you on board, @PanelSteve. Honestly, the number of dodgy DC wiring decisions I've seen documented here (and made myself, mind you) is genuinely frightening.
