Your electricity bill arrived yesterday, and it is again higher than last month. You start asking yourself if there is a better way. Companies and businesses in India have to pay a huge amount every year for their power supply. There are heavy machines in factories that consume a large amount of electricity. In offices, you have to manage lighting, cooling systems, and other electrical equipment that consume a lot of power. All of it adds up quickly.
Some businesses have already switched to solar; they are not only doing it for the environment, although it is an important factor. They have switched to solar because of the strong ROI solar panels offer. Solar panel ROI helps businesses in many ways, from reducing electricity costs to long-term financial stability.
In this blog, we will understand what solar panel ROI is, the key factors that affect it, and how to calculate it. We will also explore how investing in solar can benefit businesses in the long run and help them make smarter energy decisions.
What is Solar Panel ROI?
Solar panel ROI refers to the return you earn on your investment by saving on electricity bills after installing a solar power system. Think of it like the money you spent on the solar panel initially, then the money you save on electricity bills every month. In the long run, you will find out that your savings have surpassed your original cost, and that is your payback point.
Solar panel ROI helps you understand when your savings exceed the cost of installation. For example, when you invest ₹10 lakh in a commercial solar installation, your electricity bill reduces by ₹15,000 monthly. This would save you around 1.8 lakh rupees per annum. Now you have to divide ₹10 lakhs by ₹1.8 lakhs, and you will get the payback in around 5.5 years. Then you just continue saving money over the next 20 years or even more.
Why Solar Panel ROI Matters for Businesses?
Accountants desire figures, partners desire timeframes, and banks desire evidence before financing. ROI gives them what they need. A good solar panel ROI means solar isn’t just an expense. It becomes an investment that pays dividends for decades.
Plus, your business is comparing options. Should you upgrade equipment? Expand operations? Install solar? Looking at solar panels for business ROI helps you rank these choices against each other.
Key Factors that Affect Solar Panel ROI for Businesses?
Several things determine how fast you’ll see money back. Some you can control. Others you can’t.
How Much You Currently Pay
An increase in electricity costs increases payback. A business that pays 10 rupees per unit sees better commercial solar ROI than one that pays 5 rupees per unit. The industries that operate night shifts or use heavy machinery usually have high bills. Therefore, switching to solar power is most advantageous to them.
Your System Size
Large installations are more expensive in general, but they also help you save more. A 100kW warehouse system provides varying returns compared to a 20kW small office set up. It is important to get the size right.
Where You’re Located
Rajasthan receives more sun as compared to Kerala. However, contemporary panels are effective even in clouds. Do not think that cloudy places can be left out. Most companies in the moderate climate see high solar panel ROI.
Tax Breaks and Subsidies
This part can change the math. Businesses can claim accelerated depreciation, up to 40% in the initial year. That reduces your taxable income significantly. Government subsidies further lower your actual investment. These incentives dramatically improve solar panel ROI.
Rising Electricity Rates
Power companies tend to increase rates by 5-7 percent annually. Your solar system secures the current prices. Your savings increase every year as grid prices rise. This compound effect boosts long-term returns.
How to Calculate Solar Panel ROI With Usha Shriram Solar?
Here are a few steps that will help you calculate the right ROI for your solar panel investments:
First, add up the total costs. Equipment, installation, permits, everything. Thereafter, deduct the tax benefits or subsidies you will have.
Second, determine yearly savings. Look at last year’s bills. Determine the amount of solar that is going to offset. The majority of commercial solar installations occupy 70-100% of the daytime use.
- Third, take care of maintenance. Solar panels require minimal maintenance, however, allow 1-2 percent of the system price per year for cleaning and occasional repairs.
- Fourth, calculate payback. Divide the net investment by annual savings. That is the number of years until you break even.
- Lastly, determine the total ROI in 25 years. The majority of panels have a minimum life of that. Include increasing electricity costs. The equation is: (total lifetime savings/initial cost) x 100. (Lifetime savings-initial cost)/initial cost x 100.
Commercial Solar Panel ROI: A Real Business Case
| Solar Panel ROI (%) = [(Total Lifetime Savings − Initial Solar Investment) ÷ Initial Solar Investment] × 100 |
Where:
Total Lifetime Savings = Annual electricity savings × System lifespan (usually 25 years)
Initial Solar Investment = Total installation cost after subsidies and tax benefits
Let’s look at an actual case instead of theory.
1. A textile manufacturer in Coimbatore uses around 2,000 units daily. Their monthly electricity bill is ₹6 lakh, adding up to ₹72 lakh annually.
2. Based on their consumption, sanctioned load, and available rooftop area, they installed a commercial solar system in the range of ~300–500 kW.
3. The system generates approximately 4.5 lakh units annually.
4. At an avoided cost of ₹10 per unit, the business saves around ₹45 lakh every year.
5. The total installation cost after subsidies is about ₹1.7–1.8 crore.
6. The payback period comes to roughly 4 years.
7. Over a 25-year lifespan, the system delivers savings of more than ₹11 crore, even without factoring in future tariff hikes.
8. The commercial solar ROI exceeds 500%, making it a strong financial decision that also significantly reduces the company’s carbon footprint.
Disclaimer: Actual solar system size, savings, and ROI may vary depending on rooftop availability, sanctioned load, tariff category, and local DISCOM regulations.
Five Proven Ways to Increase Commercial Solar Panel ROI
Want better solar panel ROI? Try these approaches.
Set Up Net Metering
Net metering allows you to send surplus electricity to the grid, and thus the meter can run backwards when you are producing more power than you are consuming.
Panels continue to produce electricity during low production days or weekends, when it is a holiday. You are not using electricity, which means you are getting bill credits. This feature can lift commercial solar ROI by 15–20 % with time.
Don’t Cheap Out on Equipment
Budget panels are cheaper to purchase initially, and generate less power, and have a shorter lifespan. High-quality panels can be 20% more expensive, but they tend to have 30-40 percent higher lifetime returns. Good quality equipment basically means better solar panel ROI.
Get the Angle Right
The solar panel placement must be properly oriented and tilted. In India, south-facing panels tend to give the best results. The inclination must be more or less equal to the latitude. Professional installers can maximize placement to produce the most throughout the year.
Keep Them Clean
Dust buildup can reduce solar panel productivity, making regular cleaning essential for optimal performance. Wash quarterly, or monthly, in dusty localities. This is a low-cost solution that keeps your solar panels for business investment safe at a low cost.
Track Everything
Modern systems include monitoring apps. You can see production in real time. Sudden drops indicate problems; maybe a panel failed, or shading changed. Catching issues early prevents lost generation. That protects your solar panel ROI.
Additional Benefits of Commercial Solar Beyond ROI
ROI matters most. However, other benefits deserve mention.
Predictable Budgeting
Grid rates jump around. Solar costs stay flat for 25 years. Your finance team will love having one less variable in the budget.
Brand Image
Customers increasingly prefer sustainable businesses. Solar panels for business installations show commitment beyond profits. That resonates with modern buyers.
Energy Security
Grid outages stop production. Solar with batteries keeps you running. For critical operations, this reliability justifies the investment even before considering savings.
Property Value
Commercial buildings with solar sell faster and for more money. Lower operating costs attract better tenants. Future buyers pay premiums for commercial solar installations already in place.
Conclusion
Solar panel ROI helps you understand how solar transforms your expenses into savings with a strategic solar investment. With commercial solar installation, you get high returns while providing energy security and environmental benefits.
Switching to solar power is the only smart decision that will help you with the increasing electricity cost. Solar panels for business pay for themselves within a few years and continue to deliver for years.
