A Resource for North Carolina Homeowners Associations

What Role Do HOAs Play?

The standards, rules and requirements adopted by HOAs can have a major impact on local solar development.

North Carolina’s solar access law prevents HOAs from creating restrictions that prohibit or effectively prohibit the installation of solar PV. This law can be seen as a starting point from which HOAs have the authority to create regulations that are supportive of solar, rather than simply not restrictive.


Before creating these policies and regulations, HOAs should take the time to learn about the technical aspects of solar PV in order to understand how their rulemaking affects the performance of a PV system. Specific factors important for HOAs to understand and consider when creating regulations involving solar include array size, array orientation, array tilt and system shading.

The best practice is for HOAs to be clear and unambiguous in their standards. An example of standard language that supports solar is as follows: “Once a solar system is approved, adjoining neighbors may not build or plant structures that will obstruct solar collection, without prior approval from [the] neighbor owning the solar collectors.”


How Can HOAs Support Solar in Their Communities?

1. Understand North Carolina’s solar access law.

2. Advance community education on solar energy.

3. Clearly define what is permissible and what is not regarding solar PV in your community. This can be done by incorporating solar-specific standards into community guidelines. It is best to bring as many stakeholders to the table as possible when creating these standards.

Benefits of Residential Solar PV

Save Money

There are two primary ways a home can use the power generated by a photovoltaic (PV) system:

1. Using the electricity on-site and selling any excess back to the utility via net metering.

2. Using the PV system to supply an energy storage system (such as a battery backup system).

Each of these options saves a homeowner money on their monthly electric bill. As the upfront costs of solar are going down and electricity prices are rising, these saves are becoming even greater.

With current state and federal tax credits (worth 35% and 30%, respectively), the upfront cost of a PV system is greatly reduced. Depending upon the final upfront cost of an individual’s system, he or she can see savings well in the thousands over the PV system’s life.

North Carolina ranked 15th in the nation for CO2 emissions and generated most of its power from coal in 2011 (U.S. EIA). When it’s producing electricity, solar PV is an emissions-free energy source with great potential to reduce North Carolina’s total CO2 emissions.

A single homeowner has the potential to reduce North Carolina’s annual CO2 emissions by an average of 3.89 metric tons by installing solar panels.* If just 100 North Carolina households install solar, it has the equivalent impact of taking 82 cars off the road!

And Other Environmental Impacts

In addition to reducing CO2 emissions, solar reduces emissions of other air pollutants, such as SO2, NOx, ozone and particulate matter. These air pollutants are all hazardous to human health and the environment.

Rooftop solar also reduce land use impacts of power generation by taking advantage of space that’s already been built upon.

Raise Property Values …

According to Lawrence Berkeley National Laboratory, solar PV systems are associated with increasing property values.** The larger the system size, the greater the increase in property value. Also, the older the system is, the smaller the property value premium is. The average property value premium of a PV system of average size (3.7 kW) and average age (2.9 years) in California is $24,851 (LBNL, Exploring California PV Home Premiums).
