Frequently Asked Solar Project Questions 

What does a solar installation process look like?

The solar installation timeline can vary depending on the size and complexity of the installation. Typically, the process involves an initial consultation to assess your energy needs and site feasibility, followed by design and engineering, permitting, and finally installation.

The actual installation process can take anywhere from a few days to a few weeks, depending on the size of the system and other factors such as weather conditions.

Once installed, the system will need to be inspected and connected to the grid, which can take several more weeks. Overall, the entire process can take anywhere from a few weeks to several months, so it's important to plan ahead and work with an experienced solar installation provider to ensure a smooth and efficient installation process.

Will solar panels increase the value of my home?

Yes, installing solar panels can increase the value of your home. Studies have shown that homes with solar panel systems are more attractive to buyers, and can sell for a premium compared to homes without solar panels.

The exact amount of the premium will vary depending on factors such as the location of the home, the size of the solar panel system, and the local real estate market. 

What incentives are available for solar panel installations?

In Hawaii, homeowners can take advantage of a state tax credit that offers up to 35% of the cost of a solar panel system, up to a maximum of $5,000 per 5kWh of the system being installed.

Additionally, the federal government offers a tax credit of up to 30% of the cost of a solar panel system for 2023. This tax credit can help to significantly reduce the upfront cost of a solar panel installation, making it a more accessible option for many homeowners

*Please check with a financial advisor to see if you qualify for these incentives.

What is the lifespan of solar panels?

Solar panels have a long lifespan and can last for up to 25 to 30 years or more with proper maintenance and care. The exact lifespan of a solar panel system can vary depending on factors such as the quality of the panels, the manufacturer's warranty, and the location and climate of the installation.

However, most solar panel manufacturers offer warranties of 20 to 25 years or more, which indicates the expected lifespan of the panels. Regular maintenance and cleaning can also help to prolong the lifespan of solar panels by ensuring that they are working efficiently and effectively.

How much does a solar panel system cost on Oahu?

The cost of a solar panel system on Oahu can vary depending on a number of factors, such as the size of the system, the type of panels used, and the complexity of the installation.

Generally, a solar panel system can cost anywhere from $10,000 to $40,000. If you're also having a back up battery installed the average cost can range from $30,000 to $60,000.

What kind of warranty or guarantee is offered for solar panels?

If you perform a roofing job alongside your solar installation, we proudly offer a 5-year leak free warranty for solar panel installations.

Aside from leak-free warranties, solar panel manufacturers offer a warranty on their products, which typically covers defects and malfunctions for 10-25 years.
