"I just completed installation of a PV system with REC 430 watt Alpha Pure panels and Tesla Powerwall 3 batteries for backup through Independent Energy and they did a fantastic job from beginning to end. I've been monitoring the system using the Tesla and Netzero apps and let me tell you, I couldn't be happier. If the grid went down for an extended period of time — days or weeks, even months — we should have no problem running everything in the house like normal. Thank you Independent Energy. I highly recommend your company."

Frequently Asked Questions

How much does a Tesla Powerwall cost in Hawaii?

The cost of a Tesla Powerwall in Hawaii typically ranges from $12,000 to $16,000 installed, depending on the number of units and installation complexity. The federal solar tax credit (30%) applies to battery storage when paired with solar panels, significantly reducing your net cost.

How many Tesla Powerwalls do I need for my Oahu home?

Independent Energy Hawaii will assess your energy consumption and recommend the right number of units for your needs.

The duration depends on your home's energy usage and the number of Powerwalls installed.
