Commission advances rooftop-solar pilot; $200,000 project eyed, federal rebate could cut net cost

Staff reported progress on a rooftop-solar pilot and said the commission will present to council in the coming days seeking capital budget support. The proposed pilot budget is about $200,000; staff said a federal incentive mechanism described in the meeting as "direct pay" could cover roughly 30% of the project cost, reducing the net cost and improving payback.

Technical and financial estimates discussed at the meeting included a proposed ~100 kW installation capable of producing about 100,000 kWh a year at the safety building, a net payback horizon of about 14 years (vendor estimates ranged), and longer-term savings over a 30-year lifetime. Staff noted roof age and tree canopy as constraints in choosing sites; the safety building has a newer roof and was identified as a primary candidate. The service center and community center were discussed as later candidates, with estimated project-level costs presented for each.

Members also discussed operational resilience: the community center may be planned as an emergency center with a generator, and commissioners asked whether solar plus batteries could reduce generator sizing or costs. Staff said battery storage and generator choices are separate engineering questions but noted potential grants for emergency-resilience projects.

What happens next: staff aims to put contracts under way by October 1 and use the fall/winter window to complete work for eligibility for the federal rebate program. Commission members asked staff to continue refining budget and site selections and to monitor rebate timelines and SREC market assumptions.
