Koken means “contribution”
We took our name from the Japanese word for contribution — 貢献 — because that's the job: leave every home, and every neighborhood, better than we found it.

Common Questions
Straight answers, every time
How much does it cost?
We give real numbers up front — no inflated quotes. For solar, most installations run $15k–$30k before any available local incentives, and you own the system from day one. With $0-down financing, monthly payments are often less than your current power bill — and our up-front discount replaces the old federal tax credit, applied immediately instead of waiting on a refund.
Are your contractors licensed and insured?
Yes. Every contractor we work with is carefully vetted, licensed, and fully insured. We stand behind every install.
How long does a project take?
Most installations finish in 1–3 days. We coordinate permits, installation, and cleanup so you don't have to.
Do you offer financing?
Yes — in many cases you can start with $0 down, and monthly payments are often less than your current bill.
