These turbines give an excellent return on investment for anyone with a bit of windy land. Installed costs range from L35,000 to L165,000 and you can expect income in the region of L6,000 to L50,000, or even more if your site is very windy. A mains connection is preferable and for the larger turbines you will need three-phase but at the smaller end we can design a bespoke off-grid energy management system. For some smaller turbines, you don’t even need planning permission.
C&F
We used to offer turbines from all the major manufacturers but have been so impressed by the standard of engineering, warranty and service from C&F that we now only recommend their turbines across this power range. The large blades have a sophisticated pitching system which gets the most out of the wind in all conditions; this is coupled to an efficient, cutting edge generator to give an overall performance which beats anything else available. C&F turbines come on hydraulic tilt-up monopole towers which make service and maintenance easy and they are backed by a full ten year warranty on parts, labour and performance.
C&F Green Energy is part of the globally renowned Irish owned C&F Group. C&F was first established in 1989 in Galway, Ireland and now employs over one thousand people in over six sites worldwide. With manufacturing locations in Ireland, Germany, the UK, The Czech Republic, the Philippines and China, C&F is a global company with a local face. The proof of C&F’s engineering capabilities can be seen from a customer list which includes IBM, EMC, BMW, Mercedes, Ford, VW and Thermo King, to name but a few, all of which have awarded them multiple global contracts.
C&F Green Energy was officially established by the C&F Group in 2006. The group recognized the need to provide a more powerful and safer wind energy solution for the home, farm and business owner. With their experience in the manufacturing area, C&F set about designing an innovative wind turbine that would combine unrivalled performance and power with clean aesthetics and reliability. With this in mind the company has assembled a world class team of industrial design experts in this field to deliver solutions based on innovation and engineering excellence.
The group’s success is attributed to its unrivalled levels of workmanship quality, streamlined manufacturing processes and un-surpassed levels of customer care and retention. This team has developed an innovative range of medium-sized turbines that incorporate the same advanced technologies that are used in megawatt sized machines. Building on the company’s expertise in manufacturing and design and its global reach has enabled C&F Green Energy to offer this advanced technology at very competitive prices.
C&F’s commitment to customer service and confidence in their products are evident in the fact that all
customer contracts are directly with C&F Green Energy and all warranties are carried by C&F Green Energy. This includes the full parts, labour and service and performance warranty that is available for 10 years.
Controller/GSM
C&F have developed their own microprocessor to control their range of turbines. The microprocessor is GSM enabled allowing the machine to be remotely monitored and controlled over the internet or even by mobile phone. This facility allows us to monitor your turbine and ensure that it is operating to its full potential at all times. This provides the customer with peace of mind that their investment is continuously working for them.
Generator
Designed and built at C&F in Athenry, Co. Galway Ireland. This axial flux permanent magnet air cooled multiple generator will give a lifetime of efficient, trouble-free electrical production. This is achieved through multi plate axial configuration which also facilities modular construction with multiple independent outputs. This feature gives us the ability to design turbines to specific customer needs.
Blade Pitch Control (Pitch Actuator)
The blades are automatically controlled to optimise aerodynamic performance under different operating conditions. Bigger blades give more power but demand a more sophisticated control mechanism. C&F have adopted mega turbine pitch control technology, giving us perfect control over each model. This guarantees power production at the lowest wind speed as well as at the highest wind speeds. The overall result is the most efficient micro turbine available in the world today.
Wind Vane Cup Anemometer (Yaw Actuator)
A wind direction vane is monitored by the turbine microprocessor which then activates the yaw motor to align the turbine into the wind. This feature, usually employed on large turbines, improves performance and energy yield.
Electro Mechanical Brake
An electro mechanical brake is employed as a failsafe back-up to the blade pitch brake. This is an essential safety feature usually employed on large turbines and it acts in such a way that the brake automatically engages should a fault be detected.
Blades
Our blades are manufactured from aerospace type composite materials which are stronger than steel. The CF6/11 turbines use carbon fibre reinforced polypropylene while the larger machines use glass fibre reinforced vinyl ester.
Mast
All C&F turbines employ a monopole mast which can withstand hurricane force winds. The mast is erected using a hydraulic ram which enhances operator safety and facilitates ongoing safety.
