Solar power in Iowa

Iowa is a great place to install solar panels on your house as it's one of the sunniest places in the States and solar system production is great.

As far as incentives go there is much that could be done in Iowa to improve the uptake of clean solar power.

Iowa has cheap power this combined with only very basic incentives means that payback time on average systems around 5 kW is around 13 years.

As always you have the 30% federal tax credit as well as the State based tax credit both of these can be taken over time to reduce your tax burden.

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

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

The disadvantage of installing solar panels for your home in Iowa is that some incentives have already expired or are fully subscribed.

Payback times on solar pv systems are longer than many other states due to the low electricity prices.

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 Iowa?

Iowa State Solar Tax Credit

This is a great incentive for many in Iowa.

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

Up to 15% 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.

The even better news here really is that you can carry over the value of the credits for up to 10 years that makes the pool of people eligible to take advantage of this much bigger and should help build the solar industry in Iowa.



Net Metering in Iowa

Many people don't understand the importance of net metering policy to the residential solar industry.

Solar by its nature generates most power during the middle of the day when most people are at work or school and little power is being used in the home.

Net metering means that for every unit of surplus solar generation generated during the day you effectively get a credit for a kilowatt hour of power purchased from the grid at another time.

In Iowa Net Metering is available to the customers of MidAmerican Energy and Interstate Power and Light (IPL).

Information about Mid American Energy's net metering tariff, and IPL's tariff is available here.



Property Tax exemption in Iowa

New solar installs in Iowa are 100% tax exempt for a period of 5 years, this is an area that could easily be improved on.



Sales tax exemption for Iowa

There is 100% tax exemption on solar equipment used in a residential solar PV install.



Interconnection guidelines for solar in Iowa

Iowa has a simplified small generator interconnection process for small home solar pv systems up to 10kW in size.

You are required to have an insurance policy that covers your solar system.

Some states don't require this as it is generally covered in household insurance.

If you want a system bigger than 10kW that is still doable but may require a scoping study to determine if the local grid will be OK with your solar install or will it require work to make it ok.

There is a bunch more info about it here.

Or you could contact a local Solar Pro they will know what's what.
