Solar panels for condo roof: A how-to guide

There are many smart reasons to go solar. A solar panel system is a wise investment that can reduce electricity costs, increase the value of your property, and reduce the environmental impact of your electricity use. Luckily, solar power isn't just for single-family homes – you can transition to solar even if you belong to a condo association.

Installing solar in a condominium is more complex than in a single-family home, mainly because it involves multiple stakeholders. But don’t worry—getting yourself set up for success from the start can make the process much smoother. The most successful solar condo projects share a few key ingredients:

• A solar champion: Having a resident who acts as the primary advocate for the project will ensure that everyone involved understands the value of installing solar.

• Support of the condominium association: Association support is necessary for any project to go forward. Without it, the complicated process of installing solar on a condominium can become an impossible task.

• A contractor who has experience working with condominiums: Having a solar installer who understands the unique circumstances of condominium solar projects will give you support throughout the process and access to the information you need.

• A high percentage of owner-occupied units: Unlike owners who rent their property to tenants, unit owners who occupy their units will see direct benefits from a solar PV project, making it easier to get their support for a solar investment.

There's no one-size-fits-all solution to solar power for condos—your condominium agreement,bylaws, or homeowners association (HOA) rules will likely play a big role in determining what’s possible. Most condo solar projects fall into one of two categories:

Association projects

With an association project, a solar PV system is installed to power the building’s common areas, such as hallways, gyms, or outdoor lighting. These systems typically connect to the building's common electric meter, and any excess electricity generated may be credited back to the association’s account through net metering if it’s an option through your utility.

Association projects are popular in larger condo buildings because all unit owners collectively benefit from the reduced energy costs for shared spaces. For smaller condos, this approach can also work if unit owners agree to share the investment and benefits equally.

Single or joint unit-owner projects

In a unit-owner project, one or more condo owners can pay to install a solar panel system on the building's roof for their personal use. To move forward with this type of project, you’ll need approval from the condo association and may be required to obtain a solar easement to authorize installation and maintenance access. Some associations might also charge a fee for the use of the roof, as it’s often considered a shared space.

Unlike association-wide projects, unit-owner initiatives don’t require every resident to invest, which can make it easier to negotiate in larger condo complexes. However, your ability to proceed may depend on your building’s size and how your condo agreement defines roof rights and shared spaces.

If neither of these options is viable for you, you can also consider community solar power, either by finding an existing project or by working within your community to create a new solar installation.

What about solar in small condo buildings?

Going solar doesn't have to be complicated if you live in a condo building with just a few units. You can still choose to go solar with either an association project or a unit-owner project. The most crucial step is to engage with your fellow unit owners at the beginning of the solar shopping process to find an option everyone supports.

First things first: Know your roof rights

Before reviewing your options, you need to understand who has rights to your building's roof. Your condo agreement should usually delineate roof ownership and maintenance responsibilities. Typically, the agreement will categorize the roof as a common space, with maintenance costs and responsibilities shared equally between unit owners.

If you live in a small building or a duplex, you might own part of the roof. Regardless of whether you have individual or shared roof rights, it's good practice to work with your neighbors to find a solution that works for all of the unit owners involved.

Online resources can help you gather information on going solar

In the early stages of the solar shopping process, conduct your research so that you can communicate options with fellow unit owners and condo association members. Using a solar calculator that gives you savings estimates can provide you with valuable information to make the case for solar to your fellow unit owners and trustees.

Your installer will be an essential resource and can provide more detailed information about the options that will work best for your property. Remember – every condo situation is different, and finding a contractor with expertise will go a long way in helping you with the process of going solar.

For greater chances of success, get buy-in from neighbors

Once you've explored your equipment and financing options, it’s time to rally support for your solar project. Start by meeting with your condo association—securing their consent is crucial for making your solar plans a reality. Highlight the potential savings and collective benefits to build a strong case for going solar.

Whether you're planning a project for your own unit or the entire property, be proactive in sharing your vision and motivations with your neighbors. If you’re pursuing an association-wide project, gaining the support of fellow unit owners is essential. Be prepared to answer questions and present clear information about costs, savings, and environmental benefits to get everyone excited about the idea.

Even if you’re focused on a unit-owner project, involving your neighbors can be beneficial. You might discover like-minded neighbors who want to join your effort, potentially making it a shared project. In some cases, you could even qualify for discounts by installing a larger system that serves multiple units. Collaboration and open communication can turn your solar dream into a win for everyone.
