Energy as a Service: The Future of How You Buy Power

You subscribe to music, movies, software, and cloud storage. You might even subscribe to a meal kit or a razor blade service. So here is a question that is reshaping the energy industry: why not subscribe to your electricity too?

Energy as a Service — or EaaS — is a business model that lets you access solar panels, home batteries, energy management systems, and other clean energy technology without paying tens of thousands of dollars upfront. Instead, you pay a monthly fee, and the provider handles everything from installation to maintenance to optimization. It is the "Netflix of energy," and it is growing fast.

But is it actually a good deal? Like any subscription model, EaaS comes with trade-offs that every consumer should understand before signing a contract. Let's walk through how it works, who is offering it, what the real pros and cons are, and how to decide if it makes sense for your household.

How Energy as a Service Works

The core idea is simple: instead of buying energy equipment, you buy the energy outcomes. A service provider installs, owns, operates, and maintains the energy system — whether that is rooftop solar panels, a home battery, an EV charger, a smart thermostat, or some combination — and you pay for the service it provides.

Here is a concrete example. Under a traditional solar purchase, you might pay $20,000 to $30,000 upfront for a rooftop solar system. You own it, you maintain it, and you keep all the electricity it produces and any tax credits you qualify for.

Under an EaaS model, a company installs the same system on your roof at no cost to you. They own the panels and the inverter. You pay them a monthly fee — either a flat lease payment or a per-kilowatt-hour rate for the electricity the system produces — that is typically 10 to 30% less than what you would pay your utility for the same amount of power. The provider handles maintenance, monitoring, and any repairs for the life of the contract, which usually runs 15 to 25 years.

The Main EaaS Models for Homeowners

Solar Lease

You pay a fixed monthly amount for the use of a solar system on your property. The payment stays predictable (though some leases include annual escalators of 1 to 3%). The provider owns the system and takes responsibility for maintenance.

Power Purchase Agreement (PPA)

Instead of leasing the equipment, you agree to buy the electricity it produces at a set per-kWh rate. Your monthly bill fluctuates with production (more sun equals more electricity equals a higher bill, but also more savings versus what you would have paid the utility). PPAs often offer the lowest effective rates.

Solar + Battery Subscription

Increasingly popular in 2026, these packages bundle rooftop solar with a home battery system. The provider manages the battery's charge and discharge cycles — storing cheap solar energy during the day and using it during expensive peak hours — to maximize your savings and their return. Some programs also enroll your battery in virtual power plant programs that earn additional revenue by providing grid services.

Community Solar Subscription

If your roof is not suitable for solar — because you rent, live in a condo, or have too much shade — community solar offers an EaaS-like alternative. You subscribe to a share of a local solar farm and receive credits on your utility bill, typically saving 5 to 15% on electricity costs with no equipment on your property at all.

Who Is Offering EaaS?

The residential EaaS market is dominated by a few major players, with a growing number of regional and specialty providers.

Sunrun

Sunrun is the largest residential solar company in the United States, and its business model is essentially built on EaaS. More than 95% of Sunrun's sales come through leasing and subscription arrangements rather than direct system purchases. The company has over 106,000 customers enrolled in virtual power plant programs — a 400% increase from the previous year. Sunrun operates 3.7 gigawatt-hours of dispatchable battery capacity and is targeting 10 GWh by the end of 2028. Their battery attachment rate for new customers has reached 70%.

Sunnova

Sunnova is seeking a $3.3 billion Department of Energy loan guarantee to expand its EaaS offerings of rooftop solar, battery storage, and home energy management technology. The company is building virtual power plant programs across California, Massachusetts, Rhode Island, Texas, and Puerto Rico.

Tesla

Tesla's solar subscription offers a monthly fee for a Solar Roof or panel system, and the company's Powerwall batteries are increasingly bundled with virtual power plant participation through the Tesla app. Tesla's Autobidder platform manages grid services at scale.

Other Providers

Generac (home standby systems plus solar plus VPP integration), Schneider Electric and its GreenStruxure joint venture (commercial and industrial), Redaptive (commercial energy efficiency), and Stem Inc. (AI-driven storage optimization) all play in this space.

The Virtual Power Plant Connection

One of the most interesting developments in residential EaaS is the rise of virtual power plants — networks of home batteries that can be coordinated to act as a single large power resource for the grid.

Here is how it connects to EaaS: if you subscribe to a solar-plus-battery service, your provider may enroll your battery in a VPP program with your local utility. When the grid needs extra power during a heat wave or other peak demand event, the provider instructs your battery (and thousands of others) to discharge a small amount of stored energy to the grid. You earn credits or payments for participating, the utility avoids firing up expensive and polluting peaker plants, and the grid stays stable.

Sunrun dispatched 416 megawatts across 17 active VPP programs last year, partnering with utilities like PG&E in California and Orange & Rockland in New York to build some of the largest residential virtual power plants in the country. This is EaaS at its most sophisticated — your home battery earning money while you sleep.

The Honest Pros and Cons

Advantages of EaaS

No upfront cost. This is the big one. A rooftop solar system costs $15,000 to $30,000 to buy outright. An EaaS subscription requires $0 down. For households that want clean energy but cannot — or prefer not to — write a five-figure check, this removes the biggest barrier to entry.

Predictable monthly payments. Instead of variable utility bills that spike in summer, you get a fixed or capped monthly payment. Budget certainty is valuable, especially as residential electricity prices are projected to rise another 3% in 2026.

Maintenance is included. If an inverter fails at 3 AM, it is the provider's problem, not yours. Professional monitoring, repairs, panel cleaning, and eventual replacement are all covered. You never have to climb on your roof.

Access to latest technology. EaaS providers have an incentive to keep systems performing well. Some contracts include technology upgrades over time.

VPP revenue. Enrolled batteries can earn you money or credits by participating in grid-services programs, partially offsetting your monthly subscription cost.

Disadvantages of EaaS

Higher long-term cost. This is the most important trade-off to understand. Over a 20 to 25-year contract, leasing or subscribing to solar typically costs more in total than buying outright. The provider has to make a profit, after all. If you can afford to purchase a system and plan to stay in your home long-term, buying usually delivers better financial returns.

You forfeit tax credits and incentives. When a provider owns your solar system, they — not you — claim the available tax credits and depreciation benefits. Those incentives are factored into your lower monthly rate, but you do not get to capture them directly. Note that under current 2026 policy, the residential clean energy tax credit (Section 25D) has expired for purchased systems, though leased systems may still benefit from the commercial Section 48E credit passed through to consumers. For details on what credits remain, see our guide to IRA tax credits in 2026.

Long contracts are hard to exit. Fifteen to 25 years is a long time. If you want to sell your house, the lease or PPA either needs to transfer to the buyer (which some buyers resist) or be bought out (which can be expensive). Always read the transfer and termination clauses carefully.

Less control. The provider decides system settings, battery dispatch schedules, and VPP participation parameters. If you are someone who wants to monitor and optimize your own system, this can feel limiting.

Provider risk. If your EaaS company goes bankrupt — and several solar companies have faced financial difficulties in recent years — the ownership, maintenance, and warranty of your system can become uncertain. Research your provider's financial health before signing.

Credit requirements. Most residential EaaS providers require good credit scores to qualify, which can exclude the households that would benefit most from lower energy costs.

Is EaaS Right for You? A Decision Framework

EaaS might be a great fit if:

  • You want solar or battery storage but cannot afford a $15,000 to $30,000 upfront purchase
  • You rent or plan to move within a few years and want community solar
  • You value simplicity — someone else handles installation, maintenance, and optimization
  • You want to participate in VPP programs and earn money from your battery
  • Your roof is suitable for solar but you are uncomfortable with the financial commitment of ownership
  • You prioritize predictable monthly energy costs over maximum long-term savings

Buying might be better if:

  • You can afford to purchase and plan to stay in your home for 10+ years
  • You want to capture maximum financial returns from your solar investment
  • You prefer full control over your system and its settings
  • You are comfortable handling occasional maintenance or hiring a service provider as needed
  • Your state offers generous incentives that you would forfeit under a lease

Key questions to ask any EaaS provider:

  1. What is the total cost over the full contract term versus buying?
  2. Is there an annual price escalator, and what is the rate?
  3. What happens if I sell my home — can the contract transfer?
  4. What are the early termination fees?
  5. What is the provider's financial rating and track record?
  6. Will my battery be enrolled in VPP programs, and what do I earn?
  7. What happens to the system at the end of the contract?

The Bigger Picture: Why EaaS Matters for the Energy Transition

Beyond individual household decisions, EaaS is playing a significant role in accelerating the clean energy transition. By removing the upfront cost barrier, it makes solar, storage, and energy efficiency accessible to millions of households that would not otherwise participate. The global EaaS market for commercial and industrial customers alone is estimated to reach $221.1 billion in 2026, and the residential segment is growing at over 9% annually.

Virtual power plants built on EaaS subscriptions are creating a new kind of grid infrastructure — distributed, resilient, and responsive — that complements traditional utility-scale generation. When tens of thousands of home batteries can be coordinated to respond to grid needs in seconds, the entire power system becomes more reliable and less dependent on fossil-fuel peaker plants.

This is the future of clean energy taking shape in living rooms and garages across the country. Whether you own your system outright or subscribe to it, the destination is the same: cleaner, cheaper, more resilient energy for your home.

The Bottom Line

Energy as a Service is not a gimmick — it is a legitimate and rapidly growing way to access clean energy technology. For the right household, it provides real savings, zero upfront costs, and hassle-free maintenance. For others, buying a system outright remains the better financial play.

The key is understanding the trade-offs, reading the contract carefully, and choosing the model that matches your financial situation, time horizon, and comfort level. The good news is that whether you buy or subscribe, you are joining the clean energy transition — and that is a win for your wallet and the planet.
