As energy costs continue to rise & the impact of climate change becomes more evident, more people are turning to solar energy. But the big question remains: is solar worth it for you? Solar Return on Investment is the answer. Understanding how to calculate your solar ROI can help you decide whether investing in solar panels is a smart financial decision.
In this blog, we'll explain the simple formulas you can use to determine your solar ROI by breaking them down into easy-to-understand steps. This will help you ascertain how long it will take to take back your investment & how much you will save over the lifespan of your solar system.
What Is Solar ROI?
Solar ROI refers to the return on investment for solar energy. It is typically calculated by comparing the savings on your electricity bills over time to the total cost of installing your home solar panels.
The calculation is based on the distinction between what you spend on solar & what you save in electricity costs over a period of time. A higher ROI means you’ll recover your investment sooner and make more savings over the years.
The Simple Formula for Calculating Solar Return On Investment
To compute Solar ROI, we've to use the following formula:
ROI (%) = (Total Net Savings / Total Cost of Solar System) × 100Where:
Total Net Savings: This is the total amount you retain on your electricity bill throughout the life of your solar system - deduct any ongoing maintenance costs.
Total Cost of Solar System: This is the initial cost of building a solar system which includes all components and installation expenses (before subsidies and rebates).

Understanding the Calculation
Let us break down the processes for estimating solar ROI:
Step 1: Determine the Total Cost of Your Solar System
The Initial step is to compute the entire cost of your solar system. This cost is inclusive of the cost of procuring panels, solar inverters, wiring, installation, & any additional equipment. If there are any federal subsidies or tax credits available, you should subtract them from the overall cost of the system.
Step 2: Estimate Your Annual Savings on Electricity
Next you need to approximate how much you will save on your electricity bills per annum. This is totally dependent on the size of your solar system & the percentage of your energy consumption it can offset. To achieve this multiply your monthly electricity bill by 12 to determine how much of it your solar system will offset. Use this formula to calculate your annual savings:
Annual Savings = Monthly Electricity Bill × 12 × % Offset by SolarWhere:
- The monthly cost of electricity is the average bill.
- % Offset by solar is a portion of your electricity consumption that is covered by solar panels.
Step 3: Calculate the Total Savings Over the Lifetime of the Solar System
Now that you've determined your annual savings, you may calculate your life savings. Solar systems usually last for at least 25 years or more thus multiplying your annual savings by the number of years the system will last.
Lifetime Savings = Annual Savings × System Lifespan (in years)Step 4: Subtract Maintenance Costs (if applicable)
Solar systems generally require minimal maintenance, but it’s important to factor in any maintenance costs, such as cleaning or occasional repairs. Deduct these charges from your total savings to calculate your net savings.
Net Savings = Lifetime Savings - Total Maintenance CostsStep 5: Apply the ROI Formula
Now that you have computed the total net savings & total system cost, enter those figures into the original ROI formula:
ROI (%) = (Net Savings / Total Cost of Solar System) × 100This will show you the percentage of the return on your solar expenditure.
Understanding the Solar Payback Period
Another important thing to keep in mind when you're thinking about getting a solar system is the payback period. In simple terms, this tells you how long it will take to retain the money you have invested on the system by saving on your electricity bills. The lesser the payback period, the sooner you’ll start seeing real financial benefits from your investment. It’s a great way to measure how quickly your solar setup starts to pay for itself. It calculates how long it will take to return the cost of your solar system through reducing electric bills. A shorter payback period means that your investment will be retained sooner.
Formula:
Payback Period = Total Cost of Solar System / Annual SavingsThis will give you the time in years it will take to recover your initial investment.
Factors That Affect Solar ROI
While the numbers above provide a reasonable starting point but there are few points that can influence your solar ROI:
1. Location and Solar IrradianceThe quantity of sunlight your location receives has a big impact on how much energy your solar panels can generate. In places where solar irradiation is higher, hence, you will create more energy & save much more money on your electric bill.
2. Electricity TariffsThe higher the cost of energy in your area, the more you will save by installing solar panels. Larger electricity bills usually mean a larger ROI.
3. Solar System SizeLarger solar systems can offer a greater percentage of your electricity demand, resulting in higher savings & Return On Investment.
4. Government SubsidiesGovernment subsidies like tax credits & rebates, can significantly lower the initial cost of your solar system by enhancing ROI.
5. Maintenance and Operational CostsAlthough solar panels have modest maintenance costs, it is critical to budget for frequent cleaning, repairs, or inverter replacements, as these prices can reduce your overall savings.
Additional ROI Considerations
Increased Property ValueAdding solar panels to your home doesn’t just cut down your electricity bills, it can also give your property value a nice boost. Even though this isn’t usually counted directly when calculating your return on investment, it’s a financial upside that’s hard to ignore. In fact, many homeowners have observed that solar system equipped homes attract better offers when it’s time to sell. So, if moving is on the cards in the future, your solar setup could end up working in your favour in more ways than one.
Environmental ImpactAlthough not a financial return, the environmental benefits of installing solar panels should not be overlooked. By reducing your dependability on fossil fuels, you help reduce your carbon footprint. Commercial and Industrial Solar Rooftop Solutions also play a key role in promoting sustainability at a larger scale. This can be considered a form of "eco-ROI," contributing to the global effort against climate change.
Is Solar Worth It?Calculating your solar ROI is a basic method that can help you ascertain whether investing in a solar system is the best option for you. Using the accompanying calculations, you can calculate how much you will save throughout the life of your system & when you'll see a return on your investment.
Understand that, while the initial cost of solar panels may be significant, the long-term reserves, combined with potential government subsidies and environmental benefits, make solar an attractive investment for many individuals and businesses.
