Frequently Asked Questions

The word photovoltaic implies “light electricity” – or in other words the ability to turn light into electricity. Photovoltaics were once used almost exclusively in space to power satellites’ electrical systems.

PV cells are primarily comprised of materials called semiconductors that allow it to absorb light and convert it into electricity.

PV will save you money. It can even reduce your electric bill down to a minimum of $17 a month. Cost savings is great, but PV is also a perfect technology to help Hawaii become more sustainable by using the Sun’s natural power to generate electricity and reduce Hawaii’s dependence on oil.

The federal and state governments currently allow for an unrestricted 30% and restricted 35% in tax credits.
This may be your once in a lifetime opportunity to receive money from the government to improve your property.
Before these benefits disappear, you should consider taking advantage of the tax credits.

Based on an average size system and home, the estimated payback is 4-6 years for a residential system.

The estimated lifespan is 25 to 50 plus years with proper maintenance.

If left alone, your PV system will produce power for many years to come. However, periodic preventative inspection and maintenance will ensure maximum power production and longevity of your PV system. We recommend your panels be cleaned, your inverter, wiring and roof penetrations inspected, and maintenance by a qualified person every 6 to 12 months depending upon where you live. If you live close to the ocean or in a dusty area, these inspections should happen more frequently. You should also inspect for shade encroachment, if you have trees that are tall enough – or will get tall in the future. Please contact us if you have further questions. Solar Wave can customize a maintenance plan to suit your needs.

Sunny weather and proper installation makes a system most effective. Cloudy weather may impact the efficiency slightly, but unless it is prolonged you should not see a significant difference in panel output.

It depends on your current and projected electricity use and the efficiency of the panels you purchase.

Most times, the visual impact is not visible from a street standpoint, unless your property slopes downward. With proper installation, the panels should be adequately secured with minimal roof modification. If your roof is not suitable for panels, a solar consultant will be able to determine so during the site inspection and notify you of the possible options.

Definitely. If you don’t use a licensed contractor you become liable for the work. If should something go wrong, you won’t have the ability to file a credible claim. We recommend that you always use a licensed contractor, no matter the type of home improvement work you pursue. It is your main protection from those who seek to take advantage of a trusting public.
