This project started some time ago when I became interested in renewable energy and built a wind turbine, and since then has evolved into a self-sufficient solar energy system, reporting real energy data to the internet using a Raspberry Pi.
The generator inside the 24 foot wind turbine itself was frequently problematic and so it is not currently generating. Instead, the system is currently comprised of 400 watts of solar power, which charge 2 x 110 amp-hour batteries during the day. These power the entire LED lighting fixtures inside the house 24 / 7.
Although the system is relatively low power, the project as a whole has been a fantastic learning opportunity, and I hope that anyone fascinated by do-it-yourself renewable energy systems find the details here of great interest.
My long term plan is to acquire at least 1Kw of solar panels, and perhaps have the excess energy redirected to an immersion heater when the batteries are charged.
You'll find that almost everything was acquired on Ebay, and where possible I have included a price and a link to each piece of equipment required, as well as any useful web resources and source codes.
