Have been asked if it's possible to light a remote 1000m square building with renewables, the light's would only be for occasional use and would only need to be bright enough to check & feed the cattle only during the winter months.
The site is very exposed to all winds and was thinking of a 300w portable navitron turbine, batteries, would prefer low voltage lights to keep it simple and keep the cost down.
Ideas?

Exposed, remote, so probably not much in the way of maintenance in the winter. I might be tempted by 2d 12/24v lamps and a Rutland 913 or the land equivalent. We have had the 910s running on the marsh for in excess of 10 years now with minimal problems. We do use a dump load to stop the battery cooking in gales. If I remember right, cattle sheds are not the smallest of sheds and a fair amount of light would be needed to check the beasts properly.
OTOH what about a small genny with a string of proper bulbs. S/hand Honda seem to go forever.

I'd say the 300W turbine plus a couple of batteries and low energy lights would be a good, low-cost solution.

someone kindly point the gentleman to my long ago thread on LED floodlighting from Germany.

LED floodlighting
Would that realy work in a cattle shed of that size / height? I thought LED had a short & narrow working area? Justme |

I was installing solar pwered LED streetlights in Afg, the light pool is preety good with these so I would imagine a highbay version would be feasible

dependant upon your pocket & your actual requirements really.
Ebay Germany is very good for led product, floodlights etc, (google "colormax" led floodlights) ...uk is expensive for led "tubes" like factory CFL lighting for semi direct replacement.
big floods are available a around £150 -250 each if you hunt around, though I can really only comment on the colormax version (one of many) & another which is used by belgian fire services..

Led would be good but i think the cost would be too great. What about 12v cfl? are they any good? I have seen some 50w and 80w 12v cfl's on fleebay  Running a cheapo inverter to power lights would give me a greater gange of lamps to choose from or would this be less efficent? |

According to the doom and gloom merchants there should be enough methane within a cow shed to provide good gas-light All you have to figure out is how to couple up to the "generators".

there are some large cfls about (now also house floodlight size) & bigger commercial...
cow shed, tall airy COLD with it's own moist microclimate fog ..well ours used to be!
just remember cfls don't particularly like excessive cold so may shorten life & increase warm up times.

do they also not respond too well to poor inverters or have I got my threads mixed up? My 2ds don't like the Navitron inverter that came with the wind turbine but are fine with the Victron.

Low voltage system 12V or 24V would be a lot easier to manage than mains voltage wiring in a cattle shed. 1000 square metres is a big shed, would need something like a dozen 10 watt CFLs. but they could be divided into a few sections. One 100w solar panel would probably manage it and require very little maintenance. www.shop.solar-wind.co.uk/acatalog/energy_efficient_bulbs_12v_24v_dc_cfl.html |

Stick a pipe up the collective methane producing arses, light it, hey presto Self illumination!

I came accross solar street lighting in India and the older ones had 9watt cfl lamps and the newer ones had 9 watt led lamps, i could not really tell the difference, i think the led was brighter but the cfl seemed to work further away.
as far as 12 or 24 volt versus 240 volt argos is doing 11 watt 240 volt cfl lamps "5 for a pound" but 12 volt ones seem to be a lot more expensive. if there is going to be a reduced life due to the cold would maybe go with 240??
i like the idea of the simplicity of 12/24 volt though
