Suzhou Yueniao Machinery & Electronics Imp & Exp Co Ltd is one of the pioneer renewable energy business and has been in this field since 2002. We are dedicated exclusively to the business of small wind generator, mini hydroelectric generator and solar energy. As a manufacturer with advanced technology, we are making in our own workshop the wind turbine from 300w to 20kw with CE certificates. Beside that we are dealing with business of mini hydroelectric generator from 200W up to 60KW and solar panel from 20W to 280W. We do not claim any of its products to be the best, but we are proud to hear the owners of our products praise them. And that is what makes all the time and effort we spend on our products worthwhile. Thank you for your support!

20KW Single Phase Off-Grid Wind/Solar Hybrid System

HY-20KW, 10KW wind&10KW solar

.

A "hybrid" electric system that combines wind and solar technologies offers several advantages over either single system.

In many regions worldwide, wind speeds are relatively lower in the summer when the sun shines brightest and longest. The wind is strongest in the winter when less sunlight is available due to shorter days.  Even during the same day, in many regions worldwide, there are different and opposite wind and solar resource patterns.

Because the peak operating times for wind and solar systems occur at different times of the day and year, hybrid systems are more likely to produce electricity consistently throughout the year.  It combines the best of both worlds !

Our hybrid systems are a combination of stand-alone wind systems. For the times when neither the wind nor the solar system is producing, our hybrid systems provide power through batteries.

Performance: 3,500~4,170 AC Kilowatt-hours (kWh's) per month (depending on wind and solar resources)

This system includes:

  • 1 set of WFD10KW/240V wind turbine generator with 12m tower    
  • 20 x 250Wsolar panel              
  • 1 pc of 20KW Wind/Solar Hybrid Controller HD-20KW-240

Claims & Return Procedures
In order to be eligible for service under this warranty, the Customer must send us pictures showing his installation of the system in 5 days after the installation.

If any problem takes place within the warranty period, Notification must be provided including a description of the alleged defect, the manner in which the wind turbine was used, the serial number, and the original purchase date in addition to the name, address, and telephone number of the party requesting warranty service.

.

Note:

  1. Power Curves and Annual Energy: The performance of wind turbine systems is impossible to predict with any certainty due to the variability in the wind from location to location and from year to year. These estimates are based upon the best available information but are given as guidance only and should not be considered as a guarantee.  For a greater level of certainty we would recommend on-site wind speed monitoring for at least a year.
  2. Variation: All values are nominal as there will be some variation in manufactured product.  Specifications subject to change.
