Revolutionary Wind Technology
The Wind Array Turbine System (WATS) technology consists of several, diverse, yet inter-related pieces of technology combining the fields of aerodynamics, power electronics and digital control into a seamless range of products.
Air Blades were designed using analytical, computational fluid dynamics and empirical techniques. The blades were tested at various wind speeds to provide optimal cut-in speeds without compromising the power output at higher wind speeds. Air Blades are manufactured using high-tech composite materials designed to provide stiffness at a small weight.
The Air Blades are assembled in a hub/seat assembly that allows field configurability of three, five or seven blades enabling the installer to optimize your turbine for the wind regime present at the installation site.
This innovative electronic module is the unique enabler in taking highly variable power from an array of wind turbines and converting it to a uniform source of energy useable by most off-the-shelf grid-tie inverters.
As the turbine experiences higher than 35 MPH winds, AutoFurlz enables the system to reduce the energy incident on the turbine
As the turbine experiences higher than 35 MPH winds, AutoFurlz enables the system to reduce the energy incident on the turbine and hence provide inherent control and safety without taking away the ability of the turbine to continue to generate valuable electrical energy.
JLM has implemented a unique gearing mechanism developed specifically for using an array of wind turbines. The SmartGearbox implements an entire gearing mechanism using smart micro-controller technology.
This unique module is an integrated electromagnetic braking system designed to slow down the turbine at high winds. However, unlike our competitor’s systems, it does not reduce the output of the turbine to zero or bring the turbine to a complete stop.
Our turbine module houses all of the components to combine multiple units and to then deploy in any configuration. This module is designed for low wind regimes present in most urban and suburban environments. Depending on the annual average wind speed, it could be configured as a three, five or seven-blade module.
The Nacelle contains all the necessary hardware and software to convert the wind’s energy to electrical power with the output voltage holding steady at 30V and a current ranging from 0 to 10A. In addition, the Nacelle houses the BreezeBox and BrakeBox modules.
The metal housing is zinc plated, epoxy dipped and powder-coated. This provides a NEMA-4 (IP65) type housing that is guaranteed for 15 years.
The AutoFurlz function is designed to be activated at 35 MPH for the seven-blade rotor and is in integrated into the nacelle.
The Nacelle for the JLM turbine is designed to be mounted using a virtually limitless number of techniques. Flexible installation is at the core of our philosophy for providing attractive turbine arrays.
Here are some of the standard techniques for installing our turbines…
Most commercial buildings are constructed using either the concrete tilt-up technique or CMUs. In both cases the top edge of the wall extends past the roof line of the building. The exposed roof edge is an ideal location for installing the turbines using the parapet mount. Additionally, the Parapet Mount can also be used to install the turbine on the inside edge of the wall to hide the base. The base footing measures 6″x 10″ and the holes are 3.5″x 8″ on-center, respectively.
Tall Parapet Mount:
The tall parapet mount is 3′ taller than the standard parapet mount. It is used to double turbine density along a roof line by being able to add units between turbines using the standard parapet mount.
Wind turbine arrays are installed on or behind a wall using our wall-mount turbine stand. Note that the base is adjustable to any angle Â± 90 degrees. The base measure 6â€x 10â€ and the holes are 3.5â€ and 8â€ on-center, respectively.
JLM’s Roof Mount is used in situations where protruding the roofing layers is not acceptable. The base frame measures 8’x8′, it supports two turbine modules and can be anchored down using sand or gravel bags. This mount is often used when installers are optimizing the siting for the turbines.
When using the parapet mount, our most common of mounts, the turbines can be placed no closer than 4′-6″ from center to center. Our tall parapet mounts enable you to double the density of turbines along a roof-line making each turbine only 2′-3″ from center when alternating between tall and short parapet mounts.
Since the Small Wind Certification Council (SWCC) does not recognize the array configuration, qualifying our wind turbines using a single string inverter would be impossible. On the other hand, our customers are excited to use multiple wind turbines, configured in an array, to produce a substantial amount of energy.
To provide maximum flexibility in configuration and installation of our arrayed wind turbine technology, each Zefr wind turbine interfaces with its own dedicated micro-inverter. The micro-inverter technology, while common in the PV Solar industry, has never been used in wind turbines due to complex technology barriers. JLM’s Zefr is the first wind turbine in the world that has been successfully interfaced with a micro-inverter.
The micro-inverters used by JLM are UL1741 / IEEE1547 certified and are warrantied for 5 years. In addition, they are compatible with 208V, 3-phase or 240V, single phase grid configurations.
Given the widespread use of these micro-inverters in the PV Solar industry, configuring a hybrid system of wind and solar panels has never been easier. The AC-SGB monitoring module is configuring to not only monitor the production of the wind turbines but also keep track of PV Solar production, as well.
Harness More Energy
Using JLM’s WATS technology, multiple turbine modules can be assembled in a plethora of configurations.
The patented von Karman vortex stabilizer technology provides the opportunity to enhance the efficiency of our turbines by more than 20% using sails. These sails can be used for advertising and signage.
The sails are often replaced with Solar panels to build a hybrid system of wind and solar renewable energy.
The interview can be performed on the phone, in person or electronically. We’d like to conduct a 10-minute interview to understand what you are looking to accomplish.
Based on the finding from the Interview, we perform a quick analysis to find out if what you are interested in doing is possible with our technology.
We perform an analytical study of your site, location, building geometry, annual energy estimates, etc. and provide you with a detailed report on the possibilities at your site.
We will work with your chosen contractor and structural engineers to complete the installation process.
Detailed Proposal and Permits
We finalize the design proposal and complete a package of documentation necessary for submission to your local building department for permitting.
Building codes requires that all solar thermal installations be performed by a licensed commercial contractor. The North American Board of Certified Energy Practitioners also offers a nationally recognized solar thermal certification program. For more information, please see www.nclicensing.org.
Energy produced and used can be estimated based on demand schedule, amount of storage and the efficiency of the building’s primary water heating system. Energy savings can then be projected using current utility rates and a realistic projected rate of increase in utility prices (called an escalation rate).
