Benefits

Compared to competitors like Tesla Powerwall and Enphase Battery, the Panasonic EVERVOLT provides superior warranty coverage (12 years standard, extendable to 15 years) and better temperature tolerance, while maintaining high round-trip efficiency of 89.3%. Its installation process is notably simpler than many competitors, designed for single-person installation, and comes backed by Panasonic’s comprehensive installer support network. It’s sophisticated energy management features, including smart controls for time-of-use optimization and a user-friendly mobile app, combined with its UL 9540 safety certification and proven lithium-ion technology, make it a compelling choice for homeowners seeking a reliable and adaptable energy storage solution.

Testimonial

Switching to Panasonic EVERVOLT was the best home improvement decision we’ve made. The system’s performance has exceeded our expectations, especially during power outages. The battery backup keeps our essentials running smoothly, and we love monitoring our energy production through the user-friendly app. Our electric bills have dropped dramatically, and the sleek panel design actually enhances our home’s curb appeal. What really stands out is the comprehensive warranty and Panasonic’s reputation for reliability. After 18 months with EVERVOLT, I recommend it to anyone considering solar power.

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!

5/5

“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!”
