FAQs About Hawaii Solar Incentives
To maintain peak efficiency, we recommend a professional cleaning once a year to remove dust, pollen, or debris. Because the tiles are tempered glass, they are “slicker” than traditional shingles, often allowing rain to wash away most dirt naturally. Note: Never walk on your Solar Roof yourself; always call a Tesla-certified technician.
Unlike standard solar panels which take 1–2 days, a full Solar Roof installation typically takes 5 to 15 days. This involves removing your old roof, installing the waterproof underlayment, and precisely fitting both active (solar) and inactive glass tiles.
While not strictly required, we highly recommend the Powerwall 3. In 2026, utility “Net Metering” programs are less favorable than they used to be. Storing your own energy to use at night (self-consumption) is now the fastest way to reach your “break-even” point and ensures your home stays powered during grid outages.
