RPCS, a trusted partner of leading solar tracker manufacturer Array Technologies, Inc., will be supplying the DuraTrack HZ v3 single-axis solar tracker for the portfolio of projects. Array trackers keep the solar PV modules following the sun on its course throughout the day, optimizing energy gains and ensuring up to a 20 to 25 percent increase in energy production over fixed-tilt systems.
Knoblesdorff Energy (KE), a division of Knobelsdorff, will partner with RPCS to perform engineering, procurement, and construction (EPC) services. KE also performs startup, commissioning, and O&M services for the renewable energy market, ranking as the #1 top solar contractor in Minnesota and #24 in the nation.
RPCS and KE have worked closely over the last several years on several projects and completed nearly 20 megawatts’ worth of solar projects in 2019.
Included in the 2020 pipeline, the 1.2 MWdc Silver Lake project will be the very first solar array utilizing a combination of AP Alternatives’ ground screw foundation and the Array Technologies single axis tracker. KE will be completing the civil and electrical scope as well as the mechanical installation as the project EPC.
“Partnering with RPCS to be a part of the first solar project using AP Alternatives and Array Technologies is exciting,” said Jeff Schrimpf, General Manager, Energy of KE. “The system has allowed us to find a cost-effective alternative to standard H-pile due to poor soil conditions. Without this alternative, the project may not have been feasible to build.”
“Knobelsdorff is always wonderful to work with,” says RPCS Sales Director Patty Thornton. “They’re timely, efficient, and trustworthy. We’re excited about the upcoming pipeline, but more importantly we’re pleased to have been selected as their source for Array trackers for their projects in Minnesota.”
The portfolio of Minnesota projects will total 17 MWdc, and will be completed in 2020.

Ahead of the show’s start, RPCS members participated in the Run with the Sun 5K on Monday, spending the morning with 1,000 of their fellow solar friends. It was an exciting start to the week, with waterfalls and inclines leading to a spectacular sunrise over Salt Lake City.
On Monday night, RPCS was among the honorary guests in attendance at the Top Solar Contractors Gala, hosted by Solar Power World, where they were presented with an award for achieving a rank of No. 15 overall on the Top Solar Contractors list.

Throughout the show, there was lots of talk about RPCS’s Safe Harbor strategy with the end of the year–and the phase out of the solar investment tax credit–on the horizon.

MONTEREY, CALIF. January 29th, 2018 – RPCS is pleased to congratulate Cenergy Power and sPower on the completion of their MCE Solar One project. A local renewable energy project built on an old refinery, MCE Solar One is a new 60-acre, 10.5 MW ground mount solar farm in Richmond, California.


In 1999, I had an internship at Sunlight & Power as a laborer for solar thermal and PV installations on residences. One day a project would be in Oakland, and the next day we would be in Redwood City. Solar was few and far between; my father called it a “hobby job” …


The 11-acre array, including nearly 6,000 modules, will serve an estimated 500 to 700 homes, all DHA residents who qualify for the program and are below 185% of the federal poverty level. Not only will the program help families reduce their energy bills by nearly 20%, but it is also benefiting solar job seekers and reducing our carbon footprint. The solar garden will save 54,139 tons of C02, and is equivalent to planting 1.2 million trees, or taking 10,374 passenger vehicles off the road for one year.
