The Science Behind Solar Energy


How Much Can I Save with Solar?

If there’s one resource that Hawaii almost has too much of, it’s sunlight. While other forms of energy are scarce and expensive for residents on Oahu and Kauai, sunlight shines down on us abundantly throughout the year. By switching your home or office to a solar power system, you can harness the Sun’s energy to help you save money on air conditioning, lighting, and everything else you use energy for night and day.

3 Ways Solar Power Can Save You Money

1. Reduced Energy Bill

When you install a solar power system in your home or office, you can expect your monthly power bill to be significantly reduced. The precise amount you save will depend on the type of solar power system to choose to install. For example, whether or not your system has a battery available for storing converted power will affect whether you can continue using solar power during the night or on cloudy days and result in you either saving more or less on your monthly bill.

2. Selling Power to the Grid

Solar power systems that generate more power than you’re able to use enable the owners to sell their excess power back to the local grid. This means you could end up making money on your monthly power bill, rather than owing money.

3. Tax Credits and Incentives

Depending on whether you choose to purchase or rent your solar power system, you might qualify for federal tax credits through the investment tax credit (ITC) program, which is also called the federal solar tax credit. With this credit, you could be eligible to deduct up to 26% of the total installation costs.
Additionally, Hawaii offers a variety of tax incentives for homeowners and commercial property owners who harness solar power.


Electricity Distribution

From the inverter, the AC electricity then flows through the building’s breaker box where its distributed throughout the home to any lights or appliances, as needed.

Battery Storage and Grid Connection

Excess electricity generated by solar panels can either be stored in a battery storage unit in a home’s solar power system, or it can travel through a utility meter into your city’s power grid. In the latter case, you will actually earn money for contributing energy to the grid. In the event your solar power system does not produce enough energy to meet your needs, your home will draw supplemental energy from your local power grid.
