I have negotiated a great deal with a manufacturer of wind turbines and solar panels. The turbines are CE and ISO certified and are in use for private and government projects (including solar/wind powered street lights in China). The following descriptions come from the manufacturer. Cost of individual units does not include shipping and handling. Wind Turbines The wind turbine's power is rated at 300W and it's voltage is 12V. Start up wind speed is 2.5m/s (5.6 mph). It has nylon fiber blades with a diameter of 1.4m (a little over 4 1/2 feet) and weighs 24.2 lbs. The generator is a three-phase AC permanent magnet synchronous generator. It has an aluminum alloy body and is maintenance free. Cost: $360. Solar Panels The solar panels are rated at 30W and 12V. They have monocrystalline panels with tempered glass and heavy-duty anodized aluminum frame. Cost: $55. Controller The hybrid wind/solar controller maximizes input to charge battery for high charging efficiency. It allows braking of the turbine and protects the batteries from overcharge or short circuit. Cost: $150. Mast 3m (9'10") steel mast (I was told it is stainless and suitable for marine applications) matched to wind turbine. Cost: $200. Complete Package Wind Turbine x1 ($360) Solar Panel x2 ($110) Hybrid Wind/Solar Controller x1 ($150) Mast x1 ($200) Shipping ($100)___ Total: $920 I plan to make my order within 1 week, so if you are interested, please respond promptly. Thanks!
