This kit contains all the parts you need to start your off-grid journey.
It is a DIY micro solar PV (photovoltaic) system, which includes a 10Wp solar panel, charge regulator and voltmeter, all encased in a laser cut wooden enclosure. This can be used to power small loads such as charging mobile phones, running a small sound system or even charging a laptop. The maximum output is 50W.
The kit costs £70 (plus £15 P&P within the UK, unless you can collect from Nottingham, UK)
Here are some photos and more details:
The kit contains the solar panel and all parts within the regulator box (but does not include a lead-acid battery).
The enclosure is laser cut ply wood with ‘T’ shaped nut holders. This was prototyped using the laser cutter at Nottingham hackspace.
Knowing the battery voltage is very important, hence the unit has an in-built voltmeter. Press the button to check the voltage.
The output is via a 12V ‘cigar lighter’ automotive socket and protected via a 5A fuse. (Yes – I know I have spelt ‘output’ wrong. This one is a prototype….).
The solar panel is connected via a plug and socket. The enclosure is held with no glue, but can be easily taken apart.
Inside the case is a charge regulator, connection block, voltmeter and switch and fuse and 12V socket.
Above are all the parts included within the kit.
If you are interested in this then I can supply a kit of parts for £70 plus postage and packing (£15 within the UK as its quite heavy-around 3kgs), including solar panel, regulator, connectors and case, but excluding a battery.

Here are some photos and testimonials from a solar DIY weekend where 11 people built this kit run at Nottingham Hackspace:
“Many thanks for the excellent workshop last weekend. …(We) not only learnt a great deal, but also had an extremely enjoyable time and met lots of interesting people. If you are thinking of running any other courses, or even repeating the second part of this one again, we would be very interested in hearing about it.”
The course participants had a number of uses for these systems:
