Solar Battery in Hawaii

RevoluSun has extensive knowledge of the various tariff programs and can guide you to the solution that best fits your facilities energy demand profile. We have designed and built systems that allow our customers to avoid peak electricity prices, by installing storage solutions that allow them to store and use battery power when the grid is expensive and only purchase grid electricity when the rates are lowest.


How it Works

In typical solar systems in Hawaii, solar panels produce energy that feeds directly into your home’s power supply and feeds back into the grid. Solar power is used to directly power your home, and the excess is either wasted or sold back to the power company at a reduced rate.

When cloud cover rolls in or day turns to night, your home reverts to grid power, and you can no longer rely on solar energy.

Battery storage solves this problem by storing the excess energy that your solar panels produce during the day. If your solar panel system is providing more energy than is required for running your home, the excess is stored in Lithium-Ion cells within your battery storage solution.

This energy can be used at any time, meaning solar energy can still be used during the night or on cloudy days. Since this energy would otherwise be wasted, adding an energy storage solution can greatly reduce your electric bill.

Recent advances in battery storage solutions, specifically Lithium-Ion cells with large capacities, have several distinct advantages for residential and commercial applications:

  • Rapid discharge rates, meaning they can handle large surges in power demand
  • Ability to fully discharge, so you don’t need to constantly monitor your battery levels
  • Large decreases in the cost of battery storage over the lifetime of the battery
  • Zero maintenance is required to keep your battery healthy
  • Batteries can now operate in a wide range of temperatures, from -5℉ to 122℉

These huge leaps in battery technology, when paired with cutting-edge solar installations, mean that you can harness more power from the sun than ever before.

Reducing Electrical Costs

The greatest reduction in electrical costs when using a solar battery comes from the ability to run your electrical appliances from stored solar energy when the sun isn’t shining.

Whether it’s significant cloud cover, shading from trees, or just nighttime, a battery storage solution can use stored energy to keep your home running off-grid. With a sufficiently powered solar system, a solar battery can quickly refill during the day and have enough energy to power all of your electrical needs during the night.

But that isn’t the only way battery storage can reduce your electric bill. Battery storage can also make up the difference when your energy use exceeds the output of your solar panels. Running an air conditioner, for instance, can tap excess power from your batteries to supplement the power produced by solar panels.

This approach can lead to you paying substantially reduced costs during peak hours when electrical companies commonly charge extra to deal with high demand. When your solar batteries are charged, you’ll never have to worry about turning on energy-demanding appliances and costing a fortune on your electric bill.

Sometimes, energy companies will offer buy-back programs when your solar panels produce more energy than you use. However, this buy-back is usually at a discounted rate.

Storing your power for later use ensures you get the maximum return on your investment with a solar power system, and you can continue to sell your excess energy after your solar batteries are full.

Preventing Outages

Power outages due to downed power lines, storms, or floods can leave you unexpectedly in the dark.

Energy storage solutions offer a simple means of providing backup power while the grid is down, allowing your solar system to seamlessly deliver the energy needed to keep all of your electric appliances running until the grid comes back online. Battery storage can outlast even extended outages if sized correctly.

When the power goes out, your solar batteries can instantly pick up the slack and begin to deliver the full energy requirement for your home. There is no disconnect while you wait for your energy to kick back in — the transition is completely seamless.

Energy Storage in Hawaii

The abundance of sunshine and high energy costs make a solar battery in Hawaii a cost-effective solution for lowering your electric bill. Imported energy costs are nearly four times as high as on the mainland, making the need for a renewable energy source all too real.

Our tropical location makes solar power an abundant source of energy and allows solar panels to reach their peak efficiency, which means that battery storage can quickly be filled and provide power completely off-grid.

The average Hawaiian solar system paid for itself in just four years as of 2020. In addition, Hawaiian state tax credits are among the highest in the nation, greatly subsidizing the cost of solar systems in Hawaii.

New programs have recently been introduced which offer incentives for people who install a solar battery in Hawaii, adding to the multitude of reasons why solar power is so desirable in our state.

Tesla Powerwall Solar Battery in Hawaii

We offer the Tesla Powerwall as our premier solution for energy storage in Hawaii. The Powerwall has a large capacity, can be placed inside or outdoors, is completely weatherproof, and offers the best value for your money. It’s also backed up by a 10-year manufacturer’s warranty and has proven itself to be a reliable energy storage solution.

Large Capacity

A single Powerwall unit has a 13.4 kWh capacity. For reference, the average home in Hawaii uses 18.5kWh per day, meaning a fully charged Powerwall can provide over 17 hours of off-grid energy for a typical home.

This capacity means your battery storage can easily provide you enough electricity to make it through the night completely off-grid, provide power through extended power outages, and give you peace of mind knowing that your solar system is working at maximum capacity.

Scalable to the Size You Need

If you need even more power, multiple Powerwall units can be combined to increase their capacity. Up to 10 units can be linked together, providing a stunning 134 kWh of usable battery storage. This combination is an excellent solution for residential or commercial customers who use substantial power and can’t afford downtime.

Indoor and Outdoor Rated

The Powerwall can be installed inside or outdoors. It is completely weatherproof, meaning it can sustain years of sunshine, rain, dirt, hail, sleet, or snow. It has both an Ingress IP67 waterproof rating and a NEMA 3R rating for electrical enclosures.

Safe Design

Despite its large capacity for energy storage, the Powerwall is designed to be safe to the touch. There are no exposed wires or hot air vents, meaning you can rest assured that it won’t pose a danger to your family or pets.

Works with Existing Solar Systems in Hawaii

People who already have panels can install battery storage long after their installation. Powerwalls can be added to existing solar systems or incorporated in a new solar panel setup. We can add battery storage to your system even if we didn’t install your panels and will ensure that all of your solar components can work together properly.

Monitor Your Battery Status

The Powerwall can be monitored with the easy-to-use Tesla app. The app allows you to monitor your battery usage, customize your battery settings for individualized savings, and receive alerts before severe weather events.

With 24/7 connectivity, you’ll always know your battery’s state of charge and be aware of how much power you have remaining before needing to revert to grid power.

Sleek Installation

The Powerwall can be installed on the ground or against a wall. It offers an aesthetic, nonintrusive chassis in a slim design. Each Powerwall is just 5.75 inches thick, 45.3 inches tall, and 29.6 inches wide, giving it great versatility in placement options.

Long-Lasting Power

With any battery system, the capacity slowly begins to diminish year after year. The Tesla Powerwall’s 10-year warranty guarantees that your storage capacity will remain above 70% for the first ten years, lending a sense of security to anyone investing in energy storage.

Unlike older models of battery storage, the Lithium-Ion battery cells can be fully discharged to 0% without risking battery damage.

Programs and Incentives to Reduce Costs

Battery storage in Hawaii gives you access to several programs and incentives which can help to reduce your overall energy costs. In accordance with Hawaii’s goal to use 100% clean energy by the year 2045, the following programs have been put in place to subsidize your solar battery installation:

Home Battery Rewards Program

The Home Battery Rewards program offers direct, monthly incentives to offset your energy costs when you incorporate a Tesla Powerwall into solar systems in Hawaii. A single Powerwall will provide you with a $35 to $60 monthly incentive on your power bill, and the incentive increases for up to three Powerwalls.

This incentive is applied directly to your energy bill each month. If your electric costs are less than the incentive amount, the Hawaiian Electric Company will send you a check for the difference.

The Home Battery Rewards program started on June 7th, 2021. Incentives will continue to be applied up until June 7th, 2026, which can substantially reduce the cost of your energy bank installation. In return for these incentive payments, all you need to do is agree to have your battery storage available to the grid in case of high energy demands.

Battery Bonus

The Battery Bonus program offers a lump-sum payment for those who install energy storage in Hawaii as part of a solar system and agree to provide power to the grid.

After installing your system and having it checked, the program asks participants to make their stored energy available for 2 hours during the day every day until December 21st, 2023.

The amount of the payment depends upon how much energy you provide during those two hours and falls into three tiers:

  • 850/kW for those accepted in the first 15MW
  • $750/kW for those accepted in the next 15MW
  • $500/kW for those accepted for the final 20MW

This program was put in place to provide 50MW of renewable energy for the grid and encourage the adoption of energy storage in residential or commercial applications. Applications for the Battery Bonus program will be accepted until June 20, 2023, or until the 50MW cap has been reached.
