International door and hardware manufacturer ASSA ABLOY had been making significant strides in environmental stewardship and was ready for their own clean energy installation. But there was a problem – the selected site had difficult topography, with slopes as steep as 20% in some areas.
The cost and time associated with grading the site could have stopped the project in its tracks, as no other site was available on the property.
- Standard racking systems require significantly more grading when the site slope exceeds 7 degrees, creating cost challenges that could hinder the ROI on the deal, making project financing extremely difficult.
- Rolling topography meant that either multiple rack types would need to be used (not a feasible solution), or the entire site would have to be graded to the same level (a very expensive solution).
- A racking system that could accommodate different types of terrain while still delivering uniform installation and performance was an absolute necessity.
DCE Solar’s Contour-DB system was the best choice for this scenario due to its flexibility and ability to accommodate a greater degree of topographical changes.
Grading the site would have cost upward of $75,000. This savings applied directly to the job cost, offsetting 50 percent of the cost of the racking system just by selecting Contour-DB. The quicker installation compared against one that included grading the site, allowed ASSA ABLOY to start utilizing lower-cost clean energy sooner.
ASSA ABLOY has been able to reduce their operating costs while also following through on global environmental initiatives. In return, they enjoy being able to deliver more value and a green-aware brand to the customers they serve.
The EPC on the project, EnterSolar, was able to demonstrate that solar energy is a viable option for businesses and property owners without added site prep costs. This presents more opportunities for future installations.
With over 4,000 solar panels being used, the array will produce enough energy to offset over 2.5 million pounds of carbon dioxide from traditional electricity generation sources from entering the environment annually.
The produced kWh is enough to offset the power used by about 150 average American homes.

Have you checked out our YouTube page?
We have a ton video interviews and additional content on our YouTube page. Recently we debuted Power Forward! -- a collaboration with BayWa r.e. to discuss higher level industry topics as well as best practices / trends for running a solar business today.
Our longer running side project is The Pitch -- in which we have awkward discussions with solar manufacturers and suppliers about their new technology and ideas so that you don't have to. We've discusses everything from residential rail-less deck attaching and home solar financing to large-scale energy storage value stacking and utility-driven new home solar + storage microgrids.
We also post our Project of the Year announcements there! Interviews with this year's winners will be up starting the week of Nov. 8. Head there and subscribe today to stay on top of all this extra stuff.
