Hawaii ranks #9 in America for savings from installing solar panels on your home

Solar power in Hawaii

Hawaii is a great place to install solar panels as far as pay back times go. Your average 5kW solar PV system has a payback time of about 5 or 6 years.

The reason the solar payback is so quick in Hawaii is due to the fact that Hawaii has the highest electricity prices in the USA.

Solar Power has been going strong in Hawaii in recent years, so much so it has revealed some issues in the State's electricity networks.

You see they were never set up with solar in mind and some work is going to be required to add more renewable energy into the grid.

What are the pros and cons of buying solar panels for your home in Hawaii

The advantages of installing solar panels in Hawaii is there is both state based incentives and the federal tax credit. Lots of sunshine means a solar pv system in Hawaii is going to produce very well. Some incentives are becoming fully subscribed so best get in while you can.

The disadvantage of installing solar panels for your home in Hawaii is that some incentives have already expired or are fully subscribed, interconnection rules can be an isssue as well so best talk to a local solar pro to see what you might be eligable for. The pros here obviously outweigh the cons by far, if you own a home or busininess in Hawaii you will be kicking yourself in a few years if you didn't install solar panels while these great incentives are still around.

Enter your details to calculate the cost and savings you are likely to get from installing solar panels for your home.

Best brands of solar panels

To find the best brands of solar panels you can use America's most trusted solar panel comparison and reviews website, SolarReviews.

However, reviews of solar panels can be a bit meaningless because most consumer owners have not had any issues and so whilst solar company reviews are very important when choosing solar installers they are of less use when choosing solar panels.

For more information to help you make an informed decision about this topic, I would recommend this article about buying solar panels.

What rebates, solar tax credits and other solar incentives are available in Hawaii

Hawaii State Solar Tax Credit

This is a great incentive for many in Hawaii.

If you owe a bunch of money in State taxes you will be happy to know that your new Solar Power install is a tax write off.

Up to 35% of the value of the system will be applied as a tax credit up to a maximum credit of $5,000.

This combined with the 30% federal tax credit provides an excellent incentive to get a new solar PV system installed.

Hawaii's RPS (Renewable Portfolio Standard)

Hawaii has the most ambitious Renewable Energy Target in the USA, yes folks Hawaii aims to get to 100% renewable energy by 2045.

So utilities operating in the state must source a certain percentage of their electricity from renewable sources in a sliding scale until they hit 100% by 2045. However there is no solar specific carve out.

 


 

Net Metering in Hawaii

What net metering, they have got rid of Net Metering and replaced it with 2 systems where the new solar power system owner has to choose between the following:

Customer Grid Supply, is intended only for solar PV installations that are designed to not export any electricity to the grid.

Is it better to lease or purchase solar panels in Hawaii?

Hawaii has made various zero down solar lease and solar PPA products popular in Hawaii.

Interconnection guidelines for solar in Hawaii

Hawaii has had issues with its electricity grids as more and more solar and wind (intermittent) renewable energy has been installed over the years.

As a consequence interconnection rules have had to be amended several times.

There is a simplified standard interconnection process in place that applies to Solar PV Installs up to 10kW.

There is more info about it in the link but your best source of current info is likely to be your local solar installers.
