Is Solar Worth It in Hilo, HI? (2026 Analysis)
Hilo's abundant sunshine makes it one of the top solar markets in the country. As a smaller community of 45,703 residents, Hilo has a growing network of qualified solar installers and competitive pricing — installation costs are 20% above the U.S. average of $15,000. With a above-average solar rating of 5 peak sun hours per day, a typical homeowner can generate roughly 12,775 kWh of clean energy annually.
Why Hilo is ideal for solar: High electricity rates ($0.35/kWh) combined with above-average sun exposure create one of the fastest payback scenarios in the country. Homeowners here typically recoup their investment in just 1 years, then enjoy 24+ years of near-free electricity.
With electricity rates trending upward in Hilo, solar provides a valuable hedge — locking in energy costs for 25+ years while grid prices continue to climb. At the current rate of $0.35/kWh, your solar investment pays for itself in approximately 1 years — then delivers free electricity for the remaining 15–20 year system lifespan.
Hilo Solar Verdict
Hilo ranks as one of the faster-payback solar markets in the west, breaking even in just 1 years. Above-average sun exposure (5 hrs/day) is a key advantage. Net metering is limited in Hawaii, so pairing solar with battery storage can significantly improve your return.
