How Much Money Can You Make Investing in Solar Energy?
By Hardik BhatiaPublishedWhen someone asks "how much money can you make investing in solar," they usually get one of two answers: a homeowner story about saving on electricity bills, or a stock chart showing wild volatility. Neither answer addresses the most direct way to generate recurring income from solar energy - owning a stake in an operating solar project that sells electricity under a long-term contract.
This blog puts real numbers on all three approaches. Not hype, not projections stripped of context - actual data on what each type of solar investment has delivered, what it costs, and what the realistic range of outcomes looks like.
What Does "Making Money from Solar" Actually Look Like?
There are three fundamentally different ways to make money from solar energy, and they produce income through entirely different mechanisms.
Rooftop solar saves you money by reducing your electricity bills. You do not receive a check — your savings come from avoiding grid electricity costs. The "return" is the difference between what you would have paid your utility and what you actually pay after solar offsets your consumption. This is cost avoidance, not investment income.
Solar stocks and ETFs make you money through stock price appreciation and, in some cases, dividends. Your return depends on when you buy, when you sell, and what the market does in between. The solar industry can be booming while your stock is declining — as happened repeatedly between 2021 and 2024.
Fractional solar project ownership generates income through actual electricity sales. You own membership units in a legal entity (typically a Delaware LLC) that owns a solar project. The project sells electricity to a buyer under a Power Purchase Agreement, and your share of the revenue flows to you as monthly cash distributions. This is recurring income from a contracted revenue stream — closer to rental income from a property than to stock market gains.
The dollar amounts, risk profiles, and time horizons for each are completely different. Let us put numbers on each one.
How Much Do Homeowners Make from Rooftop Solar?
According to EnergySage data (updated January 2026), most solar shoppers save between $37,000 and $154,000 on electricity over 25 years, depending on location, electricity rates, system size, and local incentives.
The range is wide because the economics vary dramatically by state. In high-cost electricity markets like California, Connecticut, and Hawaii, homeowners can see annual savings exceeding $2,000-$4,000 per year. In lower-cost markets, savings may be closer to $1,000-$1,500 annually. ConsumerAffairs estimates an average ROI of approximately 10% for residential solar installations, though this varies significantly by location and system design.
The typical payback period - the point at which cumulative savings equal your upfront investment - ranges from 6 to 9 years when incentives are available. However, with the federal residential solar tax credit (Section 25D) terminated for expenditures made after December 31, 2025 under the One Big Beautiful Bill Act, payback periods in many markets have extended to 10 years or more for new installations.
It is important to understand what rooftop solar does and does not do. It saves you money on electricity bills — potentially a significant amount over 25 years. But it does not generate income. You do not receive monthly checks. There is no cash flow to reinvest. For homeowners, the financial case for solar is strong in many markets. For investors looking for income-producing assets, rooftop solar on your own home is not an investment vehicle - it is a household expense reduction.
How Much Can You Make from Solar Stocks?
The honest answer: anywhere from extraordinary gains to devastating losses, depending entirely on timing and market conditions.
The Invesco Solar ETF (TAN) has experienced extremely large annual swings, including triple-digit gains and significant double-digit losses over the past six years, according to Morningstar and YCharts data. In 2023 and 2024, TAN posted significant back-to-back losses while the S&P 500 delivered strong double-digit gains. In 2025, TAN posted a strong positive return after two consecutive down years.
If you had invested $10,000 in TAN at the start of 2020, your position would have more than doubled by year-end. If you had invested the same amount at the start of 2021, you would have lost money over the following three years despite global solar installations reaching new records during that period.
This disconnect between industry fundamentals and stock returns is the critical lesson for anyone considering solar stocks as an income or wealth-building strategy. According to IEA and IRENA data, global solar installations set new records in consecutive years between 2020 and 2025. Solar stocks did not deliver consistent returns in any of those years. Strong industry growth does not guarantee strong stock performance.
Solar stocks can produce exceptional returns for investors who time entries and exits well. But they are not a reliable income source — most solar-focused equities provide limited dividend income compared with traditional income-oriented investments — and their returns are driven by market sentiment rather than solar project economics. Solar stocks are generally not designed to provide predictable recurring income. If your primary goal is contracted, recurring cash flow from solar energy, equity instruments may not align with that objective.
How Much Can You Make from Fractional Solar Project Ownership?
Some fractional solar platforms, including Sustvest, target XIRRs in the 10-14% range, with monthly cash distributions in USD. These are projected returns based on contracted PPA revenue, expected generation output, and operating cost assumptions — they are not guaranteed.
To illustrate what this might look like in practice, consider the following hypothetical example. This is purely illustrative, not representative of any actual project, and does not guarantee any particular outcome.
Hypothetical scenario:
Investment amount: $5,000
Target XIRR: 12%
Distribution frequency: Monthly
PPA duration: 15 years
At a 12% XIRR with monthly distributions, an investor might expect to receive approximately $50-60 per month in distributions during the early years of the project, with the exact amount varying based on actual generation output, PPA tariff, operating costs, and currency conversion. Over a 15-year PPA term, cumulative distributions could meaningfully exceed the original investment — but the actual outcome depends on real-world project performance.
What drives the return:
The spread between the PPA tariff (the price at which the project sells electricity) and the cost of generation plus operations is the source of investor income. In India, many commercial and industrial electricity consumers face grid tariffs that are significantly higher than solar generation costs. This spread creates the margin that funds investor distributions. A wider spread generally improves project economics and can support stronger investor returns.
What this is not:
Fractional solar income is not interest on a deposit. It is not a fixed coupon like a bond. It is revenue from actual electricity sales, subject to real-world variables including weather, equipment performance, off-taker payment behavior, and currency exchange rates. The target XIRR is a projection, not a promise.

What Reduces Your Actual Returns in Fractional Solar?
The gap between projected returns and actual returns is determined by several real-world factors that every investor should understand before committing capital.
Management and platform fees reduce the gross return before distributions reach investors. These fees should be clearly disclosed in the Private Placement Memorandum. Common fee structures include an annual management fee (typically 1-2% of assets or revenue) and, in some cases, performance fees or carried interest above a preferred return threshold. Fees are a legitimate cost of professional management, but they directly reduce your net return.
Below-projected generation can occur due to lower-than-expected solar irradiance, equipment underperformance, soiling, or grid curtailment. Solar resource assessments are based on historical weather data, and actual conditions vary year to year. Annual variability of 5-10% around the long-term mean is normal. If generation falls below projections, revenue falls proportionally.
Inverter replacement costs may arise during the PPA term, as inverters have shorter lifespans than solar panels. Depending on the project structure, replacement costs may come from a dedicated reserve fund or may be deducted from distributions. Understanding who bears this cost is an important due diligence question.
Off-taker payment delays can affect the timing (though not necessarily the amount) of investor distributions. While PPAs are binding contracts, payment discipline varies by off-taker. Well-structured projects select creditworthy buyers and include contractual protections, but delays are a practical reality in some markets.
The honest takeaway: the target XIRR is the return the project is designed to deliver under expected conditions. Actual returns may be higher or lower depending on how these real-world factors play out. For a comprehensive risk assessment, see: Solar Investment Risks: What Every Accredited Investor Should Know.
How Do Solar Returns Compare to Other Passive Income Sources?
The following comparison provides approximate yield ranges as of mid-2026. Actual yields vary by specific instrument, market conditions, and timing. Verify current rates before making investment decisions.
Fractional Solar Projects
Approximate yield: 10-14% target XIRR (projected, not guaranteed)
Income frequency: Monthly
Liquidity: Low (locked for PPA duration)
Minimum investment: $500+
Return drivers: Electricity production and contracted PPA revenue
Key risk: Illiquidity, currency, counterparty
US Treasury Bonds (10-Year)
Approximate yield: 4-5% range (varies daily)
Income frequency: Semi-annual
Liquidity: High
Minimum investment: $100 (TreasuryDirect)
Return drivers: US government credit, interest rates
Key risk: Interest rate, inflation erosion
REITs (Publicly Traded)
Approximate yield: 3.5-4.5% dividend (sector-dependent, plus potential appreciation)
Income frequency: Quarterly
Liquidity: High
Minimum investment: Price of one share
Return drivers: Property values, rents, interest rates
Key risk: Interest rate sensitivity, sector-specific
High-Yield Savings Accounts
Approximate yield: 4-5% APY (rate-dependent, subject to change)
Income frequency: Monthly
Liquidity: Very high
Minimum investment: None
Return drivers: Federal funds rate, bank competition
Key risk: Rate cuts reduce yield
Dividend Growth Stocks (S&P 500 Aristocrats)
Approximate yield: 2-3% dividend (plus price appreciation)
Income frequency: Quarterly
Liquidity: High
Minimum investment: Price of one share
Return drivers: Corporate earnings, market sentiment
Key risk: Market volatility, dividend cuts
Rental Property
Approximate yield: 4-8% net rental yield (location-dependent, plus appreciation)
Income frequency: Monthly
Liquidity: Very low
Minimum investment: $50,000+ (down payment)
Return drivers: Local property market, tenant demand
Key risk: Vacancy, maintenance, tenant issues
The comparison highlights a clear trade-off pattern. Higher-yielding assets (fractional solar, rental property) require accepting illiquidity. Highly liquid assets (savings accounts, treasuries) offer lower yields. Solar project cash flows are generally driven by electricity production and contracted revenue rather than daily stock market movements - a characteristic that may be relevant for investors seeking to diversify their income sources beyond traditional financial markets.

Frequently Asked Questions
Is 10-14% XIRR realistic for solar investments? The target range is typically derived from project-level financial models based on expected generation, PPA tariffs, operating expenses, and currency assumptions. Whether a specific project achieves its target depends on actual generation output, off-taker payment behavior, currency movements, and operating costs. However, target returns are projections, not guarantees, and actual performance may differ.
Do you get paid monthly from fractional solar? Some fractional solar platforms, including Sustvest, distribute income monthly. Distributions are typically paid in USD and are proportional to the investor's membership units in the LLC. The amount varies month to month based on actual generation (which fluctuates seasonally — monsoon months in India produce less than summer months) and the timing of off-taker payments. Monthly distributions are one of the distinguishing features of fractional solar compared to bonds (semi-annual) or stocks (quarterly dividends, if any).
Can solar investment income replace a salary? For most investors, no — at least not from a single project investment. Solar investment income is best understood as a supplementary passive income stream or a portfolio diversifier, not as a primary income source. The illiquidity and long duration make it unsuitable as a replacement for employment income. However, for investors with sufficient capital allocated across multiple solar projects, the cumulative monthly distributions can contribute meaningfully to overall passive income. The key is realistic expectations: fractional solar is a long-term, patient-capital investment, not a get-rich-quick vehicle.
