Over a front door
On a small balcony
On a deck / some steps

You know the sort of thing, normally you'd have a couple of 100watt CFL jobs and 10 or so 30watt halogens that
kind of business...

Now I know you can get off the shelf stuff, but I presume without 10 hours of blazing summer sun it will be an embarrassing disappointment.... therefore wondered about knocking up something a bit more hardcore...

Say v.efficient low power LED light(s)
Decent PV panel (s)
Maybe a small wind generator
12v leisure battery
DC/DC constant current driver(s)
PIR / occupancy / day night control (to keep demand low)

Any thoughts...?

Are you on grid? If so, is there any special reason for not connecting these lights, etc, to the grid? Grid electricity isn't much more expensive than the electricity out of a battery by the time you take into account the need to replace the battery after it's done its cycles.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=9665&Focus=158452#Comment_158452 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=9665&Focus=158452#Comment_158452 Sat, 06 Oct 2012 20:50:49 +0100 WillInAberdeen http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=8736]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=9665&Focus=158453#Comment_158453 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=9665&Focus=158453#Comment_158453 Sat, 06 Oct 2012 21:06:41 +0100 James Norton
