What an 800W kit would do in Hawaii
Assuming ~5.6 peak sun hours per day and typical system losses, a standard two-panel 800W plug-in kit in Hawaii produces about 1259 kWh per year. At the state’s average residential rate of 42.5¢/kWh, that’s roughly $455 per year off your electric bill if you self-consume most of it. A typical 800W kit costs $500–$1,200, so simple payback lands in the 2–3 year range. Run your own numbers →
What this means for renters and condo owners
If you rent or own a condo in Hawaii, plug-in solar is the only realistic way to generate your own power — no roof required. Because the state hasn’t passed a dedicated law yet, a technically-compliant route is to keep the system portable, check your utility’s tariff rules, and watch this page: when a bill passes, we update it.
