Tesla Powerwall

The Tesla Powerwall stands out from competitors primarily through its exceptional power output capabilities and streamlined design. With 12kW of output power – nearly double what most competitors offer – it can handle higher electrical loads simultaneously. While other batteries may compete on individual features or price points, the Powerwall’s combination of high power output, integrated components, and intelligent features creates a comprehensive package that’s difficult for competitors to match.

Benefits

The Tesla Powerwall represents front leading technology in home energy storage, delivering a simplified yet powerful solution for homeowners seeking energy independence. As the most space-efficient battery on the market, it seamlessly integrates into any home environment while providing reliable backup power for your entire household. The Powerwall’s efficient energy management system maximizes solar energy utilization and optimizes electricity costs through intelligent load shifting and time-of-use rate management. What truly sets the Powerwall apart is its whole home backup capability, automatically detecting grid outages and transitioning to backup power in a fraction of a second, ensuring uninterrupted power to essential appliances and systems. This comprehensive solution combines Tesla’s innovative technology with reliable performance, making it an ideal choice for homeowners looking to reduce their carbon footprint while maintaining energy security.

Testimonial

The Tesla Powerwall has completely transformed how our family thinks about energy. When we installed it last spring, I was initially drawn to the sleek design and the easy-to-use app, but its true value became clear during an unexpected three-day power outage in our neighborhood. While our neighbors were scrambling to find hotels, our home stayed powered – we kept our fridge running, could charge our devices, and even ran our air conditioning. It’s amazing to watch the system automatically switch to stored power during peak hours, saving us money on our electricity bills.

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!”
