This was a practical guide produced while working for SIBAT, an NGO working in the Philippines, on a 1kW wind turbine off-grid system for remote community electrification. This work was part of a one-year placement in the Philippines funded by Engineers Without Borders UK.

This guide covers all the components required for an off-grid wind turbine system and attempts to explain the reasons for the choices and the calculations involved.
This guide is specific to the Philippines, although the general concepts are relevant to all small off-grid systems.
The guide is available here.
The design spreadsheet mentioned in the guide is not included here as it was written specifically for SIBAT, the NGO. If you would like any help designing small off-grid renewable energy systems, please email.

  1. Sorry, the link on this page was bad due to an upgrade of Joomla. It should work now. I will also email you the guide direct. Regards, Matt.

    Quoting Guest:please send me the report “wind turbine electrical system guide”, thanks very much!

  2. Hi Matt. Quick question. Do you know the formulas related to wire gauge, the number of turns, ID/OD of the coil and strength (N-rating) to how much electrical output (either and/or voltage/current) is generated? Thanks!

  3. Hi,
    I have found your following three guides, have I missed any from this series of yours?

    Wind Turbine Stator Design Guide.

    Wind Turbine Rectifier Design Guide .

    Wind turbine electrical system design guide.

    Many thanks.

    1. Hi,
      Those guides were written about 15 years ago, so please double check the info in them first!
      Hopefully they are some help to you.
      The best source of info are the books from Hugh Piggott:
      Most of the info I give comes fom Hughs books and plans.
      The only other thing I have helped write is the Energy in Development book, available to download here:

      Best regards,
