Utility costs in Hawaii are among the highest in the U.S., so it’s not uncommon to see solar panels installed as part of larger projects in order to take advantage of the state’s plentiful sunshine. After repairing a 30-year-old standing seam roof, the Word of Life Christian Center in Honolulu installed an 82 kW solar array, attached with clamps from S-5!.
To cover the cost of the roof repairs, as well as the crystalline solar panels, the Word of Life Christian Center entered into a power purchase agreement under which any unused electricity is sold back to the local power company. This required no money down and allowed the congregation to save money from day one.
The solar system consists of 241 340W P17 modules from SunPower, each secured with Mini Clamps from S-5!. Almost 50% of the roof is covered with solar panels, and the system is projected to produce 124.9 MWh in the first year.
“After the roofing work was completed, we installed the solar panels in three different portions of the roof,” explains Kurt Blum, project manager for installer Hi-Power Solar. “They were mostly southwest and southeast facing, but there was also a northwest-facing roof.”
Blum adds, “It was a pretty straightforward install. We had to work around some HVAC equipment, but that’s on almost every job. We used the S-5! clamps because they’re easy to work with and they don’t penetrate the roof. The roofer was on-site a couple times, making sure we weren’t messing up his work.”
Blum says the aluminum S-5! clamps stand up to the salty air of the island, and before any installation, the roofer coated the entire standing seam roof and gutter system with Gaco Roof Coating to improve water tightness. The solar panels were attached with approximately 450 S-5-U Mini Clamps with the DualRack Standard Rail.
“Hawaii occasionally has some hurricane-force winds, so it’s important to have a properly engineered system,” concludes Blum.
