Rooftop and solar carport canopy
Completed August 15, 2014
Installed by PhotonWorks Engineering LLP
This project was a complete redesign of a an inadequate & outdated design. Photonworks Engineering was able to modernize the design using the latest high efficiency solar modules and inverters to increase the original output by 247% within the same space as originally proposed. The PV system helped the project achieve LEED silver status and help NAVFAC achieve its renewable energy goals.
Custom carport structure
Completed June 20, 2014
Installed by Meridian Solar
The 149.76kW installation consists of 576 fixed tilt SolarWorld 260W Modules mounted on a cantilevered carport on the top level of the parking garage structure. The system is sized to produce 200MWh per year, which will provide electricity for a church, day school, coffee shop, homeless resource center, and off-site classes for our local community college. At the time of commissioning, this project was the largest solar installation in downtown Austin.
In the past, a project of this size was too risky in downtown Austin. Downtown networks have been set up to only allow electricity to flow in, creating better protection for densely populated areas. An initial concern of the project was that on the days when more solar energy was generated than needed, the excess would try and pump back into the grid causing significant problems. With this project in mind, Meridian Solar helped create a sophisticated control system that permits the solar array to be connected to the utility’s electrical service, all while prohibiting the excess generation from back feeding into the downtown network.
The control system will include one inverter and an AC utility disconnect to isolate the system from the utility grid. A minimum import relay will be installed to prevent back feed of solar photovoltaic energy to the network protectors owned by Austin Energy. In addition, a dynamic control system will be used to adjust inverter output levels to follow the customer load without back feeding photovoltaic energy to the network protectors owned by Austin Energy. Settings for the network protectors, the minimum import relay, and the dynamic controller will be adjusted and evaluated under a pilot program being conducted by Austin Energy.
From the customer:
“Through our solar energy project, we are fulfilling God’s call to be stewards of creation. In addition, as we save significant money on our utility costs, those resources enable us to fulfill other aspects of the Gospel as we care for those in the Austin community, including our homeless brothers and sisters and local service agencies.”
- St. David’s Rector, the Rev. David Boyd
“This achievement is the latest chapter in St. Davids’ long history of contributions of the Austin community.” By helping resolve difficult issues related to our electric grid, St. David’s has moved us closer to our goals for local solar generation, and has demonstrated once again the value of its longtime partnership with the City."
- Austin City Council Member Chris Riley
“We had a window of opportunity that opened with a newly created pilot program by Austin Energy, federal rebates, low interest rates, and the advancement of technology. Everything came together so well with the help of Austin Energy and Meridian Solar, we were finally able to carry it out”.

Custom pavilion and canopy structure

System details - Burke parking canopy:
System details - Burke solar pavilion:
Burke’s solar electric solar parking canopies and solar pavilion allows Burke to generate thousands of kilowatt hours of clean, renewable electric over the life of the system. Burke’s renewable energy investment was constructed using 1,505 American-made SolarWorld 245 watt polycrystalline solar modules mounted on five large raised solar canopies and 50 SolarWorld 245 watt polycrystalline solar modules mounted on a custom designed solar pavilion structure. The solar modules on the parking canopies feed two PVP Powered inverters that convert the DC solar generated electricity to AC electricity for general use on Burke’s campus. Monitoring is by Locus Energy. The electric car charging stations were manufactured by Eaton.
This is the largest solar electric system in downtown Cincinnati and the only solar parking canopy system in downtown Cincinnati when installed.
The system features a gently curved design to match the existing aesthetics present on Burke’s LEED Gold seven acre campus in downtown Cincinnati. Not only does this unique solar installation generate approximately 30% of Burke’s electrical generation requirements, but it also shades the employees’ cars year round. Burke employees that own electric cars appreciate the free on-site EV charging stations. Burke employees use the solar pavilion for break times, lunches, company gatherings, and team meetings.
“Our new solar canopy installations have generated employee excitement, given us an edge in recruiting, and impresses clients,” said Mary Beth Mapstone, CPA, Senior Vice President of Finance and Administrative Services for Burke. “This is priceless!”

“I’m pleased to write this product recommendation for SolarWorld SW-175 monocrystalline modules. These modules were installed last year as part of a highly-visible project at the Orange County Convention Center (OCCC). The project was awarded a $2.5M state grant, involved several state and local government partners, and had a total value in excess of $8M. This project features a one-megawatt rooftop photovoltaic system which is the largest of its type in the Southeast United States.
Johnson Controls, Inc. was awarded a design/build contract by Orange County for a project called the Solar Photovoltaic Demonstration Facility and Climate Change Education Center. Essentially, the scope of the project was to install a one-megawatt PV system, four smaller “demonstration” PV systems, and to build-out an education center. The one-megawatt system used 5,808 SW-175’s and two of the smaller systems used an additional 124 of the same modules.
As you may be aware, SolarWorld modules are recognized in the industry as being high quality and highly reliable. Based on our experience thus far, we certainly agree. OCCC has also been impressed by the electrical output of our one-megawatt system. Energy production during the first 12 months of operation exceeded projections by 18.4%. Further information about the OCCC Solar Project, including live energy production and environmental data can be found at www.occc.net/community/solar_project.asp” – Jerry Daigle, Deputy General Manager, OCCC - June 28, 2010

"We believe that the combination of size and public accessibility, makes this solar array the most impactful array of any in the entire country," said Mark Fisher, Senior Director of Facilities, Planning, and Sustainability at the Cincinnati Zoo. "No where else has an array of this magnitude been placed in such an urban environment, allowing our visitors, and the general public at large, to be able to see first hand what solar photovoltaic energy is all about. The education potential of this advanced energy project is off the charts."
"As the greenest Zoo in America, there is no better place to showcase this technology and to help the public understand that not only is this technology the right thing to do for our energy future, but it makes absolute financial sense as well," said Thane Maynard, Executive Director of the Cincinnati Zoo.
