Sunspear Energy re-powers Wholesale Unlimited’s Waipahu solar array

Sunspear Energy completed a 165.4 kW rooftop solar re-power project for Wholesale Unlimited at the company’s Waipahu warehouse in Hawai‘i. The upgrade preserves the site’s legacy net energy metering status while targeting an 85% cut in utility costs and stronger clean-energy output.

Why it matters: - The project upgrades an aging commercial solar asset instead of replacing it, extending the life and value of Wholesale Unlimited’s original 2012 rooftop investment. - Sunspear Energy designed the new system to preserve Wholesale Unlimited’s existing legacy Net Energy Metering position, which can be difficult to retain during major system changes. - The re-power is expected to cut utility costs by about 85% and reduce long-term energy expenses at the Waipahu warehouse.

What happened: - Sunspear Energy completed a 165.4 kW rooftop solar re-power project for Wholesale Unlimited at the company’s Waipahu warehouse in Honolulu. - The project replaced a significantly underperforming solar array installed in 2012. - The new system uses JA Solar 440-watt modules, Pegasus racking and SolarEdge inverters with SolarEdge monitoring. - The original modules were rated at about 230 watts each. - The retired modules were recycled through Inter-Island Solar Supply’s PV Recycling Program. - Sunspear coordinated a silicone-over-metal restoration of the warehouse roof before installing the new system.

The details: - Wholesale Unlimited installed solar on the Waipahu warehouse in 2012, three years before Hawai‘i adopted its 100% renewable portfolio standard for electricity. - The new array is designed to generate substantially more electricity from the same rooftop area. - The upgraded system is projected to produce about 268,960 kWh, or 269 MWh, of clean electricity each year. - The system is expected to average more than 22,000 kWh per month. - Project estimates show more than $50,000 in annual utility savings and about $1.5 million in savings over 30 years, based on current assumptions and subject to actual production, electricity use and future utility rates. - Sunspear added Solar Insure SI-Commercial warranty coverage as part of the project. - SI-Commercial includes 30-year coverage for qualifying solar panels and 20-year coverage for qualifying inverters, including parts, labor and shipping for covered repairs. - The program also includes manufacturer and installer default protection backed by Zurich, an A.M. Best A+ rated insurer. - Sunspear said the old equipment was underperforming, and the new design allows the rooftop to deliver higher output while meeting utility requirements.

Between the lines: - The project reflects a broader strategy for first-generation commercial solar sites: re-powering can unlock better performance without sacrificing valuable legacy program benefits. - The installation also shows how newer panel and inverter technology can nearly double output per panel compared with equipment installed in 2012. - Wholesale Unlimited’s solar adoption fits the company’s long history in Hawai‘i, where the business has operated since 1965. - The upgrade pairs production gains with warranty protection, which can matter because equipment warranties alone may not cover labor and service costs. - The project is also expected to prevent about 423,720 pounds, or 192.2 metric tons, of CO₂-equivalent emissions each year, equal to taking 42 gasoline-powered passenger vehicles off the road.

What’s next: - Sunspear Energy says the project points to more opportunities to re-power Hawai‘i’s early commercial solar installations with modern equipment. - Wholesale Unlimited will now operate the warehouse solar array as a long-term energy asset with higher output and preserved NEM status. - Sunspear will continue offering commercial solar and storage projects, along with in-house design, engineering, installation, monitoring, service and maintenance.

The bottom line: - Wholesale Unlimited turned a dated solar installation into a higher-yielding asset without giving up its legacy energy program advantages.
