All You Need to Know About Calculating Your Solar Payback Period

The environmental benefits of solar panels are widely known. Besides being a clean source, it’s also an abundant source of energy. However, there’s an attractive financial aspect to it as well. In many cases, installing solar panels can increase the property value of the user. Solar PV systems can even function as a tool for investment. For instance, apart from generating surplus energy, solar panels can help users save massively on electricity bills. However, an interesting question that often haunts many solar enthusiasts is: How long does it take for solar panels to pay for themselves? We will answer the question with the aid of a tool which is known as a solar panel payback calculator. For starters, let’s try to understand what the term solar panel payback implies.

Solar Panel Payback Period

The solar payback period is an estimation of how long it will take you to recover your solar energy investment. Cheap equipment and increasing electricity rates are resulting in people moving towards solar technology. Thus, it’s important to understand the solar payback period from an investment point of view. Further, comparing quotes from solar installers is also an easy method to understand the financial merits of various solar investment options. It will help you in case you are wondering how long it takes to break even on solar panels. And that brings us to our next theme: 

Solar Payback Period Calculation

To estimate the time it takes to realise solar panel return on investment, it’s important to consider the combined costs along with annual returns on going solar. Here are some of the expenses and incentives that you must consider:

Gross Expense of Solar Panels

The gross expense of installing solar panels depends on the size of the system you select along with the equipment that the system comprises of.

Average Monthly Current Usage

The size of the solar PV system that you need as well as the amount of energy that you can save depends on your monthly current usage. Interestingly, the higher your current bills are, the faster you will be able to recover your solar investments.

Total Energy Generation

Although reputed solar installers provide you with the best panels that match your energy needs, the actual energy generation will also depend on practical constraints like the weather, size of your roof, and the solar radiation that it receives.

Solar Subsidy

In India, government grants a 30 per cent subsidy to all Indian states. However, the subsidy is available only on made-in-India panels on grid-connected setup. The consumer needs to submit a report with financial and technical details, maintenance and operations plan and solar monitoring and reporting report to the Ministry of New and Renewable Energy (MNRE).

Accelerated Depreciation Benefit

Solar power gets promoted in private sectors as well as corporate sector by the government, enabling them to avail better rate of depreciation. Accelerated depreciation can be stated as a fast rate of depreciation of the assets in the primary years of business. In this case, assets value will decrease in the early years due to high depreciation expense. However, there will be little impact on asset value due to lower depreciation.

Although the normal depreciation rate for a plant is 15 percent. However, as per section 32 of the Income Tax Act, commercial and industrial users can benefit and claim up to 40 percent from the tax benefits due to accelerated depreciation.

Steps to Calculate Your Solar Payback Period

You can either use a solar panel payback calculator or follow this method: 

Calculate Combined Expense: To determine the combined costs, you need to subtract the rebates and incentives from the total cost of the solar PV system.

Calculate Annual Benefits: Add your annual financial benefits along with any avoided current costs or any other incentives.

Final Calculation: Divide the combined expense by your annual benefits to determine the number of years needed to recover investment costs. Thereafter, every month of savings can be regarded as your direct benefit.
