What else do you lot get up to besides solar?

My shepherds hut's basically become a test bed for every off-grid contraption known to man, so I've gone full tinkerer mode — microhydro's the latest obsession after solar got a bit predictable. There's something deeply satisfying about watching water do all the work whilst you're sat inside with a cuppa.

Outside of that, I'm genuinely into the woodworking side of things. Built my own battery enclosure for the Victron setup, which looked dodgy until it didn't, and now I'm designing a proper log store that doesn't leak rainwater into my electrics. Turns out carpentry and electrical safety go hand-in-hand when you're living the dream.

I've also started keeping bees — partly for honey, partly because they're better company than most forum members (no offence). Plus they're ace for the smallholding vibe.

On the less practical end, I've become obsessed with optimising the cabin's insulation, which is code for "arguing with my partner about whether we need seventeen different temperature sensors." We don't. We absolutely have seventeen.

Proper curious what everyone else does though — are there gardeners, foragers, people who've gone full bushcraft? Or is it all just tinkering with Victron equipment and pretending your lithium battery setup is a personality? (Asking for a friend who definitely has too many solar panels.)

What keeps you lot occupied when the sun's being a lazy sod?

Microhydro's genuinely the move if you've got decent head and flow. I've been running a modest setup on the narrowboat for three years now—nothing mad, just a 400W Pelton wheel fed from a spring-fed tank. The consistency is brilliant compared to solar; winter actually becomes your golden season rather than a write-off.

The real game-changer for me was pairing it with a small battery bank and a hybrid inverter (Victron in my case). Means you're not fighting voltage fluctuations when demand spikes.

Only heads-up: the civil engineering side's more involved than most realise. Survey your water source properly, work out the actual pressure drop, factor in maintenance access. I spent more time with a level and measuring tape than I expected.

What's your available head looking like? That'll dictate everything.

Microhydro's brilliant if the geography works out. I've been eyeing it for years but the stream through our property's too sluggish most of the year — dried up completely last summer which killed that idea pretty quickly.

Garden office setup's kept me occupied instead. Got a decent battery bank paired with a Victron MPPT, couple of panels on the roof. Works a treat for powering through winter when solar's pants. Added a small wind turbine last month as backup, though the neighbours weren't thrilled about the noise at first.

Reckon the combo of solar + battery + something else (wind, hydro, whatever you've got) is the real sweet spot. Solar alone left me short too many times. What sort of flow rate are you getting @Renogy_Nerd?

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 flow makes a real difference to battery health.

Main thing though: get a proper survey done first. Looks deceptive on paper. I nearly went down a rabbit hole with what I thought was 3m head, turned out to be 1.5m once I actually measured it properly. That's the difference between viable and expensive wall decoration.

What's your head and estimated flow rate? And have you thought about sediment management? Freezing temperatures around here means blocked intakes are a genuine winter problem. Worth building in a settling tank upstream if you haven't already.

Mate, microhydro's brilliant but don't sleep on the seasonal inconsistency unless you've already mapped your flow patterns across a full year. I went down this rabbit hole on the narrowboat side of things — even a modest head can deliver surprisingly consistent power, but come August when the streams dry up, you're back to solar and batteries anyway.

What's caught me off guard is how site-specific the whole thing is. The math looks gorgeous on paper, then you realise your neighbour's upstream and there's legal faff with water rights depending on where you are in the country.

The real win I've found is pairing it with EV charging infrastructure if you're planning ahead. A small hydro setup that runs year-round gives you that baseline generation that makes charging logistics actually manageable — solar alone leaves me juggling charging windows constantly.

If you've genuinely got decent head and flow, you're looking at something Victron-friendly with a decent charge controller that can handle variable input. That's where the tinkering gets fun. Have you done a proper survey yet or still in the fantasy phase?

The seasonal flow thing @Spider mentions is absolutely spot on. I learnt that the hard way with a static caravan setup a few years back — had this brilliant little stream running through the neighbouring field, tested it religiously for months during summer, got all excited about a Turgo runner, and come autumn it was basically a trickle.

What nobody really mentions is the planning side. You'll need to check abstraction licences depending on your region — Environment Agency gets twitchy about water extraction in some areas. Worth ringing them first before you sink money into a Sunset Generator or similar.

The real win with microhydro though? It's the consistency factor. Solar's great but dead in winter when you need the power most. My boat's got a hybrid setup now and honestly, if I had flowing water access I'd be tempted to ditch half the panels. A modest 1kW setup running 24/7 beats 6kW of panels that barely output anything November through January.

The upfront is mental though. Whereas you can start small with Renogy panels and build up, microhydro's more of an all-in investment. Still worth exploring

Been running a hybrid setup on my boat for years now and microhydro's genuinely the unsung hero of the lot. @Spider's spot on about flow patterns — I spent a frustrating winter thinking my system had failed when it was just seasonal runoff dropping off a cliff.

What I've found works is pairing it with solid battery storage so you're not entirely dependent on consistent flow. Victron's monitoring gear is worth every penny for understanding what's actually happening in real-time rather than guessing.

Beyond that, I've gotten into proper water management — filtration, treatment, the lot. Makes a huge difference to system longevity. Also been experimenting with waste heat recovery from the genset, which sounds fancy but it's surprisingly straightforward to retrofit.

The cabin's basically my workshop at this point too. Might not be as glamorous as chasing microhydro heads, but getting the fundamentals bulletproof (insulation, thermal mass, ventilation) saves you from throwing money at power generation you don't actually need.

What's your water source like for the microhydro? That'll make or break whether it's worth the graft.

I've got a boat conversion running parallel to the main off-grid setup, and honestly microhydro's been the revelation for me too. What's caught me out though is the infrastructure side — not just the flow mapping @Spider mentioned, but the actual installation logistics.

Had a nightmare getting a Pelton wheel mounted on a decent head without demolishing the banks. Took three seasons of trial and error before I worked out that you're better off accepting a lower head and optimising the penstock diameter instead. The maths looked neat on paper until reality hit.

The real win I've found is stacking it with battery management properly — a good MPPT isn't going to cut it when your microhydro's generating 24/7 and your battery bank's already charged. Had to retrofit a proper load controller (Victron's diversion unit, in the end) to dump excess into immersion heating. Changed the whole picture.

If you're genuinely getting seasonal inconsistency where you are, don't underestimate what a modest solar array still brings to the party during low-water months. Sounds backwards after going all-in on hydro, but the hybrid's what

Got a small stream running past the mooring so I've been eyeing microhydro myself. Main issue I've found is the head drop — sounds dull but it's everything. Spent a weekend surveying the stretch with a level and honestly thought I had decent potential until the maths told me otherwise.

The seasonal thing @OhmsLaw mentioned is real. Winter's fine but come summer the flow drops enough that I'm back relying on battery reserves. Mixed blessing — forces you to actually size your storage properly rather than just throwing panels at the problem.

What's worked better for me on the boat is combining it with solar as a proper tandem rather than treating microhydro as the main event. The Victron setup I've got handles the switching automatically, which takes the guesswork out. You end up with something more resilient than either alone.

The appeal of microhydro is the consistency once you've got it right, but be prepared for the surveying headache. If you've got genuine year-round flow with decent gradient it's brilliant. If not, you're building complexity for marginal gains.

Worth the effort if your site's suitable though. Beats

Microhydro's brilliant if you've got the resource, but the real game-changer for me has been realising how much seasonal variation kills consistency. My static caravan's on a site with a tiny beck, and I spent ages measuring head and flow only to discover summer drought absolutely tanks the output when I need cooling most.

What I've found works better as a complement rather than replacement is coupling it with proper battery sizing and a modest wind turbine. The two together cover the seasonal gaps solar and microhydro individually leave. Winter's when both solar and hydro underperform on my setup — wind tends to be more reliable then.

The other thing worth mentioning: microhydro permitting can be a right pain depending on your local water authority. Checked with mine before investing anything substantial and got told I'd need abstraction licences. Might be worth @SimonThompson checking that angle before committing to installation costs.

If you're genuinely set on it though, Fogstar's intake systems are solid and actually scale down properly for low-head installations, unlike some of the overspec'd stuff out there.

Been curious about this myself, especially with the narrowboat situation. Water's always flowing past the mooring, but I've heard the permitting side's an absolute nightmare — Environment Agency getting twitchy about abstractions and all that. How are you lot navigating the regulatory side without ending up in planning hell?

The stream-to-battery conversion seems elegant in theory, but I'm wondering about real-world reliability. Does it handle the seasonal flow variation decently, or does it become a bit temperamental come summer when the water's barely trickling? And maintenance-wise — is it a case of checking it monthly or are you constantly clearing debris?

Asking because I've got a decent fall where we're moored, but I'd rather not invest in a Pelton wheel setup only to realise the paperwork makes it unviable. @SimonThompson, did you manage to sort the head drop calculations in the end? What were your actual figures?

Might be worth exploring as a battery-charging supplement to the solar array rather than a replacement, depending on what you're seeing seasonally.

Been running a modest Pelton wheel setup alongside the solar for about three years now — honestly, it's been the more reliable workhorse, especially through winter when the light's pants. The beauty is it doesn't care about cloud cover.

Main thing nobody mentions until you're elbow-deep in it: the screening. Debris clogs everything something chronic. I've got a simple settling tank with a 1mm mesh that needs cleaning fortnightly, more often after storms. Worth the bother though — my Victron charge controller barely sees voltage dips anymore.

@SimonThompson — head drop's the real constraint, isn't it? I'm only getting about 4 metres vertical but manage 400W steady flow in spring/autumn. If you're serious, get a flow/head calculator sorted first. Saves months of guessing.

The civil side's where people stumble. Environment Agency involvement depends on your catchment and volume — worth checking before you dig trenches. My early attempts at diverting flow round the caravan got a bit creative. Lesson learned.

Microhydro + solar is the proper combination. One covers the other's weak

Microhydro's genuinely underrated if you've got a decent head and flow. I've been eyeing it for ages but never had the gradient on my bit of land — completely flat, which is annoying when you're surrounded by folk with proper streams running through their properties.

@BurnWalker — worth checking your riparian rights first if you're on a mooring. Environment Agency can be a bit picky about abstractions, even small ones. Some narrowboat setups use submersible turbines in the canal itself, but that's a different headache entirely.

The thing that gets me about microhydro versus solar is the consistency. Solar's seasonal and weather-dependent, but water keeps flowing regardless. @RetiredEngineer72's right that it often ends up more reliable long-term. I've heard good things about the Turgo designs too if you've not got massive head — more forgiving than Peltons for variable flow.

Only real downside I've seen is the silt and debris management. Needs regular maintenance to keep the intake clear, especially after heavy rain. Still beats faffing with panel cleaning in winter though.

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 maybe £400 all in and it's been surprisingly consistent through winter when solar's rubbish.

@RetiredEngineer72 three years with a Pelton wheel sounds solid. What's your actual maintenance like? I'm wondering if the silt/debris side of things is as annoying as people reckon.

@BurnWalker worth checking permissions first though — riparian rights can be dodgy depending where you're moored. Some waterways trust are stricter than others about abstraction, even tiny setups.

The thing I've noticed with people who've gone all-in on hydro is they still end up with batteries because the flow changes seasonally anyway. So it's less "replace solar" and more "fill the gaps differently" innit. Seems like a solid combo if you're not moving around.

Got a small stream running through the property here, been meaning to sort microhydro for ages. Reckon the real challenge is the pipework and getting planning sorted rather than the actual turbine. @RetiredEngineer72 how'd you manage the maintenance side? Seems like it'd need regular checks unlike solar which just sits there doing its thing.
