Common Questions About Hawaii Energy Upgrades
What energy services does Alternate Energy Hawaii offer?
AEI provides solar PV, battery storage, solar water heating, energy efficient air conditioning, roofing, electrical services, and EV charging support for Hawaii homes and businesses.
Can I combine solar panels with battery backup?
Yes. Many Hawaii customers plan solar and battery storage together so they can use more onsite solar energy and improve backup power during outages.
