Solar Batteries

Nearly 100% of all new solar installations now include a battery, and here’s why:

Solar batteries come with an initial cost, which might make you wonder why you should add this expense to your system when solar panels generate power on their own.

Without batteries, about 60% of your home’s solar production goes to waste. Solar batteries are the solution, as they capture excess energy during the day, which can then be utilized when needed, improving your return on investment. Beyond cost savings, these battery systems also offer essential power during outages and enhance your home’s resilience and provide peace of mind.

Status: The program is capped at 50 megawatts (MW), as of right now we are at 6.2 MW.

  • Currently customers who are accepted into the program will receive $850 per kilowatt (kW).
  • After the first 15 MW is filled, the next 15 MW of committed capacity will receive $750 per kW.
  • After the next 15 MW is used the last 20 MW of committed capacity will receive $500 per kW.

Customers that are not currently enrolled in the company’s Net Energy Metering (NEM) Program will receive a fixed monthly bill credit for energy exported to the grid for three years. The credit is an amount equivalent to the respective retail rate for electricity exported during the two-hour period. After these three years are completed any underlying interconnection tariff export rates, if any, will apply.

Customers who wish to participate with an existing solar system and are presently enrolled in a customer energy program (such as Net Energy Metering, and Grid Supply or others) will continue to receive full benefits from these programs. Up to 5 kW of new panels may be added under existing programs. There is no limit on the size of an individual customer’s battery.

If you would like to add more than 5 kW of additional capacity of PV, it is possible as long as you still adhere to a 2:1 PV to battery output ratio. These apply to any interconnection tariff customers!


“We wholeheartedly recommend Independent Energy Hawaii for all your solar photovoltaic system needs. From our initial conversations with Desta to the final inspection with James, every interaction was extraordinarily positive. The team’s knowledge, honesty, and professionalism was exceptional. The whole process was done efficiently and reliably and we couldn’t be more appreciative. Every member of the team was professional, competent, and respectful in their dealings with us.”

“Easily the most professional crew I ever had the pleasure of doing business with, and I never felt alone or in the dark thanks to Desta. He helped me with all my questions and I loved the fact that he was just a phone call away. Dedication to something like that is just hard to find nowadays. This company was a breath of fresh air for me and I wish I could do such an awesome crew justice with such a simple review. 10/10″

“Desta, Adam, Mike, Garrison and the rest of the Independent Energy Team are amazing. They were knowledgeable, responsive and helpful throughout our whole solar process. When issues came up (as they always do with projects), they went the extra mile to make sure everything worked properly.
Our panels and battery were installed on time as promised and are working great – just got our first ever $26 HECO bill!
This company cares about helping people and doing quality work, which is very rare these days. Hands down the best experience I’ve had with a company for home improvement/renovations. Highly recommend!”
