Yeah, had similar luck with mine on the boat. Grabbed four 250W Canadas off a bloke in Bristol who was upgrading — cost me about £320 total.

The real question is degradation rate vs. initial cost. Those older panels like @RetiredNurse49's Kyoceras will degrade slower per year simply because they've already taken most of the hit in year...

Been through this with my shepherd's hut setup—ended up 48V and haven't looked back, but context matters here. For a Sprinter retrofit specifically, @Rob1963's got it right.

@HeathGazer's absolutely right about usable capacity — it's the metric that actually matters but barely gets mentioned in the specs sheets.

The geometry constraint is absolutely brutal on narrowboats—you're essentially trying to pack a cottage electrical system into about 2 cubic metres of engine room space.

The infrastructure point @SimonKelly raises is spot on — that's what properly caught me out. You're not just living differently, you're essentially running a small power station and water...

Been running a hybrid setup on my boat for years now and microhydro's genuinely the unsung hero of the lot.

The efficiency question @MarineAlan raises is worth quantifying. I ran this comparison on my static caravan (similar roof angle to a narrowboat) using Victron monitoring—flat installation gave me...

Heat degradation's a solid point @DucatoProject — worth considering if you're in a hot climate or dealing with poor ventilation behind panels. I've got a mix of both on my shepherd's hut setup,...

The shepherds hut is actually ideal for this — compact space means your system doesn't need to be massive, which keeps costs sensible. A few questions before you size everything: What's your...

Thirty years and you're only now introducing yourself? Mate, you've been getting free knowledge this whole time while we've been arguing about battery chemistry in the comments section. Seriously...

Spot on about weight distribution, @LindaClark90. On my setup I went for a split array rather than clustering everything at one end — spreads the load better across the roof structure. For...

What weight distribution approach did you use, @HollyGazer? I'm eyeing up panels for my narrowboat and wondering if the same principles apply — I've got limited roof space and don't want to create...

Good timing on this — roof loading is the bit most people skip and then regret. Worth checking your motorhome's manual for the actual weight limit; manufacturers are often conservative but it's...

Been through this process twice now with my garden office setup, so thought I'd share what I've learned. Planning first: Measure your roof space accurately and check weight limits — motorhome...

@DodgyCaptain brilliant to have you aboard. Transit's a proper workhorse—you've picked a good platform. South Wales is ideal for off-grid thinking too, especially if you're planning to park up...

The efficiency gains are real, but I'd add that the initial cost hit is brutal if you're not cycling regularly.

The real kicker is that a motorhome's chassis electrical system actually matters, whereas most campervans are basically just a van with a battery bolted in the back and hope as the management...

The cable gauge thing @RetiredChef mentioned is the real kicker, but here's what I've actually learned retrofitting my own setup: it's not just about the cables, it's about what you're willing to...

Got a fridge in my tiny house setup, so bit of real-world here — the inrush spike is mental. Compressor kicks in and you're looking at 3-4x the running draw for a few seconds. With your 48V...
