What is community solar and how does it compare to home solar?

What is community solar?

Community solar is a program that allows multiple households or businesses to share the benefits of a single, centrally located solar array often called a solar farm. Instead of installing panels on your own property, you subscribe to a portion of the farm's energy output. In return, you receive credits on your monthly electric bill based on how much power your share generates.

These programs are typically offered through local utilities or third-party developers and are designed for renters, people with shaded roofs, or homeowners who cannot or prefer not to install their own panels.

How community solar compares to home solar

Both community solar and home solar can lower your electricity costs and reduce your carbon footprint, but they differ in several important ways. Home solar requires installing panels on your property. Community solar uses off-site infrastructure.

Costs and upfront investment

Home solar usually involves a significant upfront cost for equipment and installation, though financing and leases are available. Community solar typically requires no upfront payment. You simply subscribe, and your savings appear as credits on your bill.

Ownership and savings

When you own home solar panels, you have direct control over your energy generation and can maximize savings over the life of the system, which is often 25 to 30 years. Your savings depend on your local utility rates, net metering policies, and the amount of sunlight your roof receives.

With community solar, you do not own any equipment. Your savings come as a fixed discount on the electricity generated by your share. That discount is typically smaller than the savings from full ownership of a home system, but the financial risk is also lower. There is no maintenance, no equipment to repair, and no roof aging to worry about.

Maintenance and responsibility

• Home solar: You are responsible for cleaning panels, monitoring performance, and any repairs. Most systems come with a 20- to 25-year warranty, but you must manage the process.
• Community solar: The solar farm operator handles all maintenance and operations. You simply pay your subscription and receive your credits.

Eligibility and location

Home solar works best if you have a south-facing roof with good sun exposure, own your home, and can invest in or finance the system.

Community solar is open to more people, including renters and those with shaded or unsuitable roofs. However, you must live within the service area of the specific solar farm. Availability is limited to regions where community solar programs are active.

Portability

Home solar stays with the property. If you move, you may need to sell your house with the panels or arrange to transfer the lease or loan.

Community solar subscriptions are often portable within the same utility territory. If you move to another home in the same area, you can take your subscription with you, provided the new property is still eligible.

Key factors to consider before choosing

Every situation is unique. Here are some factors to weigh:

1. Your roof's suitability - A roof that gets good sun and is in good condition makes home solar a strong option. If not, community solar is worth investigating.
2. Your financial goals - If you have the capital and want maximum long-term savings, home solar ownership may be the better choice. If you prefer no upfront cost and less risk, community solar fits that profile.
3. Local programs and incentives - Check with your utility or state energy office. Some regions have robust community solar programs with clear savings. Others offer strong net metering policies that make home solar more attractive. Rules and incentives vary widely by location.
4. How long you plan to stay in your home - Home solar typically pays back its upfront cost over 7 to 12 years. If you plan to move sooner, community solar may make more sense.

The bottom line

Community solar and home solar are both effective ways to lower your electricity costs and use renewable energy. Your choice depends on your property, your financial situation, and what programs are available in your area. Neither option is universally better. The right answer is the one that fits your specific circumstances and goals.

As with any major home energy decision, it is wise to research local rules, compare offers from multiple providers, and consult a trusted energy professional if needed.
