Community Solar vs. Rooftop Solar: Which Is Right for You?
Solar energy is one of the most cost-effective and practical ways to reduce your carbon footprint and lower your electricity bill. The cost of solar has dropped by more than 70% over the past decade, and today more Americans than ever have realistic options to go solar — whether they own their home or rent it, whether their roof is ideal or unsuitable for panels.
But choosing solar is no longer a single decision. There are now two distinct paths: rooftop solar and community solar. Both harness renewable energy from the sun. Both help reduce dependence on fossil fuels. And both can reduce monthly electricity costs. However, they work differently, cost differently, and suit different types of households.
This guide covers how each option works, what each costs, who each is best for, and how to decide which path makes the most sense for your situation.
What Is Rooftop Solar?
Rooftop solar involves solar panels physically installed on your roof. The panels use photovoltaic (PV) technology to convert sunlight into electricity that powers your home directly.
A solar installer assesses your home’s energy usage, roof orientation, available surface area, and local sunlight hours to design a system sized to your needs. Residential systems typically range from 6 kW to 12 kW in capacity, depending on household size and consumption.
Any excess electricity your system generates can be fed back into the utility grid. Through a mechanism called net metering, your utility credits you for that surplus energy, which then offsets what you draw from the grid at night or on overcast days. Net metering policies vary by state, but many require utilities to offer credits at or near the full retail electricity rate.
Rooftop solar can also be paired with battery storage systems, allowing households to store energy for use after dark or during grid outages — an important feature in areas prone to power disruptions or extreme weather.
The typical lifespan of a rooftop solar system is 25 to 30 years, and most panels carry performance warranties guaranteeing at least 80% of rated output over that period.
What Is Community Solar?
Community solar — sometimes called “shared solar” or a “solar garden” — works on a fundamentally different model. Rather than panels on your own roof, you subscribe to a share of a larger solar farm located elsewhere in your region. These farms are typically built on unused land, brownfield sites, or open rural areas.
The farm generates electricity and sends it directly into the local utility grid. In return, your utility applies bill credits to your monthly electricity statement, representing your portion of the energy the farm produced. You do not power your home directly from the farm; instead, your subscription generates credits that reduce what you owe your utility each month.
Most community solar subscribers receive a 10% to 25% discount on the portion of their bill offset by their subscription credits. Programs typically require no upfront costs, no installation, no roof assessments, and no home visits. The solar company owns and maintains the farm — subscribers have no maintenance responsibilities.
Community solar availability varies by state. As of 2024, more than 40 U.S. states have some form of community solar program, with strong programs in New York, Illinois, Massachusetts, Minnesota, Colorado, and Maryland.
How Do Rooftop Solar and Community Solar Differ?
Both options generate clean, renewable energy and help reduce electricity costs. The differences come down to five core factors:
- Location of the solar panels: Rooftop solar panels are on your property. Community solar panels are at a remote farm, often miles from your home.
- Ownership: With rooftop solar, you can own your system outright (or lease it). With community solar, you subscribe to energy produced by equipment owned and operated by a third party.
- Cost structure: Rooftop solar typically requires a significant upfront investment, though financing is widely available. Community solar has little to no upfront cost and works on a subscription model.
- Accessibility: Rooftop solar is generally available only to homeowners with suitable roofs. Community solar is open to renters, condo owners, those with shaded or structurally unsuitable roofs, and anyone who prefers not to install panels.
- Long-term financial return: Rooftop solar, particularly when owned outright, offers greater long-term financial gains. Community solar delivers consistent, modest, and immediate savings, but does not build home equity or generate the same cumulative return.
Rooftop Solar: Costs and Financial Incentives
The national average cost for a residential rooftop solar installation is approximately $2.50 to $3.50 per watt before incentives. For a typical 8 kW system, that translates to a total cost of roughly $20,000 to $28,000.
State-level costs vary. Installations in Massachusetts and New York tend to be higher, while systems in Illinois, Minnesota, and many Sun Belt states are more affordable.
The Federal Investment Tax Credit (ITC)
The most significant financial incentive for rooftop solar is the federal Investment Tax Credit (ITC), which allows homeowners to deduct 30% of the total installation cost from their federal income taxes. For a $24,000 system, that credit reduces the effective cost to $16,800. The 30% credit is available through 2032 under the Inflation Reduction Act.
Additional Incentives
Many states offer additional benefits on top of the federal credit, including:
- State income tax credits
- Sales tax exemptions on solar equipment
- Property tax exemptions on solar-related home value increases
- Net metering compensation for excess energy
Payback Period and Long-Term Savings
Most homeowners who purchase their systems outright recover their investment within 6 to 12 years. After that, electricity is essentially free for the remaining life of the system. Total savings over a system’s lifetime commonly range from $20,000 to more than $60,000, depending on local electricity rates and how those rates change over time.
For households that prefer not to pay upfront, financing options include:
- Solar loans — you own the system and pay over time
- Solar leases — a third party owns the system; you pay a monthly fee
- Power Purchase Agreements (PPAs) — you pay per kilowatt-hour at a rate below your utility’s price
Community Solar: Costs and Savings
Community solar’s cost model is straightforward. Subscribers pay a monthly fee for their share of the solar farm’s output. Bill credits applied to their utility account are worth more than the subscription fee — typically resulting in savings of 10% to 25% on the portion of their electricity bill covered by the subscription.
In practical terms, most residential subscribers save $5 to $30 per month, depending on their energy usage and the program’s terms. There are generally no enrollment fees, no equipment costs, and no installation expenses.
Some programs are month-to-month. Others require contracts of 1 to 5 years. It is important to understand cancellation terms before signing up, especially if there is a possibility of relocation.
Because community solar subscribers do not own any equipment, they are not eligible for the 30% federal ITC or most rooftop-specific state incentives. The savings are real, but more modest than what rooftop solar ownership can generate over the long term.
Community solar is increasingly designed with low- and moderate-income households in mind. According to NREL, as of February 2025, 24 states and the District of Columbia have policies enabling community solar, and 83% of those states include specific provisions for low- and moderate-income subscribers. In documented low-income projects, participants have seen average electricity bill savings of 33%, according to NREL’s own project data.
The U.S. Department of Energy’s National Community Solar Partnership (NCSP+) is actively expanding affordable community solar access nationwide. Community solar capacity in the United States has also grown nearly 500% since 2018 — from 1.5 gigawatts to more than 7.8 gigawatts by 2024 — reflecting the rapid pace of that expansion.
Who Should Choose Rooftop Solar?
Rooftop solar is the stronger choice when the following conditions apply:
- You own your home and plan to stay for at least 7 to 10 years
- Your roof is in good condition — relatively new, structurally sound, and ideally south-facing with limited shading
- Your monthly electricity bill is $100 or higher — the higher your current energy costs, the faster solar pays for itself
- You want maximum long-term financial return — owning your system builds home equity and eliminates electricity costs over time
- You want energy independence — paired with battery storage, rooftop solar can significantly reduce grid dependence and provide backup power during outages
- You are in a state with strong net metering policies — states like California, Massachusetts, New York, and Hawaii offer particularly favorable conditions
For Hawaii residents especially, rooftop solar is an exceptionally strong investment. Electricity rates in Hawaii are among the highest in the nation, and solar resources are abundant year-round. Working with an experienced big island solar company is one of the best first steps toward energy independence in the Aloha State — and toward significant long-term savings on some of the country’s highest utility bills.
Who Should Choose Community Solar?
Community solar is the right fit for a wide range of households that cannot access or prefer not to pursue rooftop solar.
- Renters and apartment dwellers — community solar is the most realistic solar option for the millions of Americans who do not own their home.
- Homeowners with unsuitable roofs — research from the National Renewable Energy Laboratory (NREL) found that only about 57% of U.S. residential rooftops are technically suitable for solar panels due to shading, orientation, structural limitations, or insufficient surface area
- People who want immediate savings with no upfront cost — community solar delivers savings from day one with zero capital investment
- Those who move frequently — many subscriptions can be transferred within a utility’s service territory or cancelled with reasonable notice; rooftop solar does not offer this flexibility
- HOA-restricted homeowners — some homeowners associations restrict or prohibit rooftop panel installations; community solar sidesteps this barrier entirely
- People who want to go green without managing equipment — community solar requires no maintenance, no monitoring, and no home visits; it is the simplest way to participate in renewable energy
Environmental Benefits: Rooftop Solar vs. Community Solar
Both options displace fossil fuel-generated electricity with clean, renewable energy, and both contribute meaningfully to reducing greenhouse gas emissions.
Rooftop solar generates power on-site and delivers it with minimal transmission losses — the energy consumed in a home is produced just feet away. This makes it one of the most efficient ways to decarbonize individual energy use.
Community solar also displaces grid electricity with clean energy, though the power travels through the grid before reaching end users. Transmission losses are slightly higher, but the environmental benefit remains substantial. A 2 MW community solar farm, for example, can offset carbon emissions equivalent to removing approximately 400 to 500 cars from the road each year.
Importantly, community solar extends clean energy access to households that would otherwise have no solar option — renters, low-income households, and those in multi-family buildings. This expands the reach and impact of the solar transition significantly.
Neither option is universally “greener.” Both contribute to reduced carbon emissions and a more sustainable energy future. The better environmental choice is simply the one that is accessible and feasible for your household.
What Happens When You Move?
With rooftop solar, your options depend on how you acquired the system:
- If you own the system outright, the panels add value to your home. Studies consistently show solar homes sell faster and at a premium — Zillow research found an average value increase of about 4% for homes with solar. The panels transfer with the property.
- If you have a solar lease or PPA, the new buyer will need to assume the agreement, or you may need to pay a buyout fee. This can complicate a home sale if not handled proactively.
With community solar, moving is typically much simpler. Most programs allow you to transfer your subscription to a new address within the same utility’s service territory, or cancel with a short notice period. Some charge a modest cancellation fee; others are month-to-month with no penalty at all. For anyone who relocates frequently, community solar is the more practical and flexible option.

Practical Checklist: Which Option Is Right for You?
Choose rooftop solar if:
- You own your home and plan to stay at least 7–10 years
- Your roof is in good condition and receives ample direct sunlight
- Your monthly electricity bill is $100 or more
- You want to maximize long-term savings and build home equity
- You want the option of battery storage and grid independence
- You are in a state with strong net metering and solar incentive programs
Choose community solar if:
- You rent your home or live in a multi-family building
- Your roof is shaded, aging, or structurally unsuitable for panels
- You want immediate savings with zero upfront cost
- Your HOA restricts rooftop solar
- You move frequently and need subscription flexibility
- You want to support clean energy without taking on equipment ownership
Consider both if:
- You own your home, but your rooftop system cannot meet 100% of your electricity needs — a community solar subscription can cover the remaining portion
- You are planning to replace your roof before installing panels and want to participate in solar in the meantime
Frequently Asked Questions (FAQ)
Can I participate in community solar if I already have rooftop panels?
In most cases, yes — but combined credits generally cannot exceed 100% of your monthly electricity bill. Some utilities place restrictions on dual participation, so it is worth confirming with your utility provider before signing up.
Does community solar require any work or installation at my home?
No. Community solar requires no installation, no panels, no wiring, and no home visits. Enrollment is typically done online using your utility account information.
Will rooftop solar raise my property taxes?
In many states, no. A growing number of states have enacted property tax exemptions for the increased home value resulting from rooftop solar. Check your state’s specific policy, as exemptions vary.
Is community solar available where I live?
More than 40 states have community solar programs, but availability varies by utility and region. Contact your utility directly or check the NREL’s community solar database to find programs near you.
How long does rooftop solar installation take?
From contract signing to a live system, the process typically takes 2 to 4 months — covering system design, permitting, installation (usually 1 to 3 days), inspection, and utility interconnection approval.
Can renters access rooftop solar?
Generally, no — unless a landlord installs panels and passes savings to tenants, which is uncommon. Community solar is the most practical solar option for renters.
What is the difference between a solar lease and community solar?
A solar lease involves panels installed on your property by a third party — you pay a monthly lease fee to use the energy they produce. Community solar involves no on-site installation. You subscribe to a remote solar farm and receive utility bill credits. Both avoid equipment ownership, but their structure and financial terms differ significantly.
Does rooftop solar work in cloudy or overcast climates?
Yes. Solar panels generate electricity from daylight, not just direct sunlight. Systems in cities like Seattle and Portland perform well year-round. Germany, one of the cloudiest countries in Europe, is among the world’s leading solar energy markets.
Do I qualify for the 30% federal tax credit?
To qualify for the ITC, you must purchase (not lease) a rooftop solar system and have sufficient federal tax liability to absorb the credit. Community solar subscribers do not qualify. Homeowners who finance their system through a solar loan typically do qualify, since they own the equipment.
The Bottom Line
Solar energy — in both its rooftop and community forms — is one of the most effective tools available to households working to reduce their carbon footprint, lower electricity costs, and support the transition to clean energy. The technology is proven, the economics are favorable, and the options are expanding.
Rooftop solar offers greater long-term financial returns and the opportunity to generate your own clean power on-site. Community solar offers broader access, lower barriers, and an inclusive model that reaches renters, apartment dwellers, and households that rooftop installation cannot serve.
Neither option is better in every situation. The right choice is the one that fits your home, your finances, and your goals. Increasingly, the question is not whether to go solar — it is simply which path to take.
For Hawaii residents weighing rooftop solar, the combination of high electricity rates and year-round sunshine makes the economics particularly compelling. Consulting a trusted solar company is a practical first step toward understanding your options and making the most of the clean energy resources available in the Aloha State.
