EETN's Matt Caldwell is the first professional in the state of Tennessee to obtain NABCEPs certification for Photovoltaic System Inspector. "This is really great for Matt. I'm proud of our team and our dedication to constantly improving our knowledge of solar PV installation, testing and maintenance. I really can't say enough about how impressive an accomplishment this is for Matt." - Robbie Thomas, President
EETN and partner Valcor Solutions completed work on 10.8MW solar PV installation for the Eastern Kentucky Power Cooperative in Lexington, KY. EETN/Valcor were the electrical, pile and civil subcontractor for the general contractor Lendlease. The fixed tilt portion of the project was SolarFlexRack G3X and the single axis tracker was ATI. This project was an exercise in handling difficult subterranean characteristics that affected civil and pile structural design.
"This project was very challenging on our pile team. The geotechnical analysis showed shallow bedrock that ended up preventing 35% of driven piles from reaching minimum embedment. We poured concrete for 554 spread footers for driven piles that did not meet required embedment. The team handled the extensive remediation in stride enabling project completion on schedule." - Terry Hamer, Director of Operations.
As part of their ongoing relationship with Lendlease, EETN has started construction on a 2.5 MW DC solar PV system near Roanoke Rapids, NC. The ATI single axis tracker project is expected to be complete in less than 2 months.
EETN is the electrical and mechanical subcontractor for this project. "When we perform virtually the entire install, it is very easy for us to be flexible and continue to make progress despite any minor hiccups. I think Lendlease appreciates our ability to do that and limit any conflicts between different trades. EETN is able to shift personnel from one trade to another to enable effective progress." - Terry Hamer - EETN Project Manager
EETN was awarded a contract to install 7MW DC by LendLease. The installation was in Halifax NC and was scheduled for 3 months of site work. EETN installed Solar FlexRack's G3X contour following racking system. The installation included 2400 driven piles for racking mount. EETN's pile driving team completed the project with 5 piles needing remediation.
"I am extremely impressed with what the team was able to accomplish. We took on a task that was relatively new to us and our team was nearly perfect on the first attempt. I can't say enough about the quality of people we have at EETN" - Robbie Thomas, President
The EETN team reached mechanical completion of this project on March 31, 2017.
EETN install team commissioned this 132 kW DC - 98 kW AC system last week. EETN was awarded a subcontract to perform racking, module and electrical install in June 2016. The parking canopy is installed on top of a 5 story parking garage at the Verde at Greenbelt luxury apartment complex in Greenbelt, MD. The location of the array presented significant difficulties in array install. The innovative install team at EETN completed the array with 5 weeks of on-site work. There was a short delay in work while the install team waited on the apartment's electrical equipment room to be completed. The parking canopy is a critical component in the apartment complex being a LEED Gold Certified building.
EETN is very pleased to be a part of LendLease's construction team and very proud of our contribution to completing this LEED Gold Certified project.
EETN recently completed a 94 kW parking canopy project at the Fiatele Teo Army Reserve Building in Pago Pago, AS. EETN was the EPC contractor for this micro-grid project. Pago Pago is located on the island of Tutuila. The island of Tutuila is powered by several diesel generators and Solar PV power. The Grid on the island is small – approximately 20 MW of peak load. As additional Solar has been installed on the island, the local utility -American Samoa Power Authority (ASPA) has found it difficult to adjust equipment in the event of a cloud related power transient. As a result, ASPA requires battery back-up and power smoothing function for installs greater than 30kW on the island.
EETN designed a system utilizing the Princeton Power DRI-100 Inverter to provide the power smoothing function in the event of a cloud related power transient on the system.
In addition to the micro-grid aspect of this installation, The customer desired the ability to clean the panels with a temporary walk way. With the space available, EETN was able to devise a less expensive option and instead provided a scissor lift and panel spacing to enable regular cleaning.
The corrosive salt spray environment required significant consideration for corrosion prevention. EETN designed a system using PVC and stainless steel hardware on a hot dip galvanized structural steel frame to prevent corrosion.
EETN's superior design team and install crew including Young Energy Solutions, completed a very effective install.
