S implification is one of the key objectives of the solar industry, but the path to get there, ironically, is super detailed. Removing components to simplify a racking system, being compatible (and compliant) with a broad range of suppliers and just generally re-thinking what's already been established is a deliberate and labor-intensive trial-and-error process. The Ecolibrium Solar office in Boulder, Colo., is a monument to the relentless process of simplification, and maybe it's just the immediate proximity of craft breweries and, um, agricultural entrepreneurs, but the Ecolibrium team seems cool with it. On its face, there is nothing remarkable to see here, just a standard office tucked in the back of an office park, (save all of the tables and cornhole boards made of PV ), but located in the warehouse is its product development and testing facility that is a certified partner lab of TÜV Rheinland Group. This partnership is a boon for simplification. Ecolibrium is able to test and certify modules for UL 2703 compliance in seven days and make a priority of the mod- ules that need immediate certification. Without in-house testing, a company must wait until a lab can test the module, which can take up to several weeks or more. "It's a big deal and enables us to be very responsive to our customers' needs," says Chris Berg, engineering manager. "Installers often change modules based on availability. Being able to test quickly means we can certify modules as needed. Our UL 2703 listings enable customers and plan reviewers to see if the module specified is approved with our products." In just the last six or seven months alone, Ecolibrium added around 109 modules to its UL 2703 certification list- ings. This is what I'm talking about: Being a certified lab for TÜV Rheinland and testing UL compliance is so much work. To maintain the partnership, Ecolibrium must submit reports that prove its testing tools are calibrated properly. These calibration certificates require cross checking and validation of every tool used — covering everything from torque wrenches to tape measures. Yes, even the tape measures must be independently measured to assure validity of results. I'm exhausted just writing about it. Let's turn this into a series of pictures to make it simpler for an editor like me. SOLARBUILDERMAG.COM | 9 Load Test The Ecolibrium lab tests mod- ules to this minimum and beyond — for 30 minutes each — checking for any amount of deformation or slippage. They do this with hun- dreds of pounds of sandbags, depending on target loads, taking photos of each component before and after each test. Look at all of these. Installers often change modules based on availability, so being able to test in-house is a big time savings.
