What is the Advantage and Disadvantage of ROI Metrics for Commercial Battery Storage

Financial proposition

‍

Check now

A commercial solar system is a financial proposition so: 

• Salesperson must understand financial concepts
• Both from a borrower’s perspective and also 
• From a business owner investing their money into something other than solar

‍

Case study, 100 kW system

‍

A business owner is contemplating a 100 kW solar system to negate his incredibly high electricity bill but this is one of other options he has looked at:

• Could invest the money in the bank
• May spend more on marketing and advertising
• Purchase another machine

‍

You need to know the value of money

‍

Now money has a value and in a previous presentation we looked at: 

• Present value
• Future value
• Net present value.

But what about ROI ( Return on investment),IRR ( Internal rate of return) and Payback period?

The question is what is the relationship between all these financial concepts?

Before that we have to look at the commercial solar system details and make some assumptions.

‍

A Commercial solar project

‍

In this example we will look at a commercial solar investment:

• 100 kW system
• Cost to the business is $100,000
• The W.A.C.C. ( weighted average cost of capital ) is 10%
• The length of the investment is 6 years

‍

Assumptions on the 100 kW system

‍

The assumptions around this particular system include:

• The system is installed in Melbourne, Australia, North facing
• Energy produced per 1 kW installed is 3.6 kWh on average
• Initial electricity price is $0.25 kWh
• Feed in tariff price is fixed at $0.7 kWh
• Electricity price increases 2% every year
• System maintenance is $500 and increases 2% every year after
• 80% of the solar goes to the loads, 20% to the grid

‍

ROI

‍

Below you can see the savings per year and the total savings after 6 x years is $170,097.54. So what is the ROI?

ROI

Return on investment (ROI) is an approximate measure of an investment's profitability 

ROI= (Net Return  on  Investment)/(Cost  of  Investment) x 100%

• So: ($170,097.54-$100,000)/$100,000 X 100%
•  = 70.10%

ROI: pros and cons

‍

Advantages of Return on Investment (ROI:

• It is a relatively uncomplicated metric
• Easy to calculate 
• As a measurement, it is not likely to be misunderstood

The disadvantages though are:

• It does not take into account the holding period of an investment, time period
• In this case 6 x years
• ROI does not adjust for risk
• Figures can be exaggerated if all the expected costs are not included in the calculation

‍

Annualised ROI

Annualized ROI helps account for a key omission in standard ROI—namely, how long an investment is held. 

• Annualised ROI= ((1 + ROI)1/n  - 1) X 100%
• Where n is the number of years of the investment,  
• Annualised ROI = 9.26%
• A big difference between the standard ROI of 70.1%

Solar produces benefits for longer than 6 years!

With the scenario we have looked at,the time period is 6 years but with solar the reality is that the system will produce for far longer than that.

Let’s look at 10 years for a variety of measures:

• Total savings after 10 years is $292,585.78
• ROI is 192% but
• Annualised ROI is 11.3%

‍

There is another measure

‍

What about payback period? Is this a valid measure of the worth of an investment?What is the Payback Period? 

Payback period (PBP) is the time (number of years) it takes for the cash flows of incomes from a particular project to cover the initial investment. 

When a CFO faces a choice, he will prefer the project with the shortest payback period.

Payback period: pros and cons

Advantages of Payback Period

• Simple to Use and Easy to Understand
• All that you need to calculate the payback period is the project’s initial cost 
• Annual cash flows

‍

Disadvantages of payback periods

• Ignores Time Value of Money
• This distorts the true value of the cash flows
• Can use the Discounted Payback Period that can do away with this disadvantage.

‍

So what is the payback period for this scenario?

‍

The cost of the system is $100,000 and the payback period turns out to be a little over 3.5 years.

But if we look at the discounted payback figure we get a different result as this takes into account the time value of money. 

In fact the payback is a little under 5 years ( 5 year point present value savings of $109,715.2)

Conclusion

‍

There are many ways that the worth of a particular investment, 6 years, in this case a 100 kW solar system, can be looked at:

• Using NPV have a figure of $20,924.17 
• An IRR of 17%
• ROI of 70.10%
• Annualised ROI of 9.26%
• Payback period of under 4 x years
• Discounted payback period of just under 5 x years

‍

The importance of understanding these financial metrics applies to both the renewable energy sales person presenting these proposals and the business person who needs to make an assessment on a range of options.

Are you considering investing in solar storage systems but worried about the initial costs? You're not alone. Many people focus solely on the upfront expenses, missing out on the broader picture. In this article, we’ll explore the hidden ROI factors in solar storage systems that can significantly impact your investment over time, especially in Latin American markets.

Understanding Solar Storage Systems

What Are Solar Storage Systems?

Solar storage systems are designed to capture and store energy generated by solar panels. This stored energy can then be used when sunlight is unavailable, such as at night or during cloudy days.

Why Are Solar Storage Systems Important?

• Energy Independence: They allow you to rely less on the grid.

• Cost Savings: By using stored energy, you can reduce your electricity bills.

• Environmental Impact: They contribute to a cleaner environment by maximizing the use of renewable energy.

Beyond Initial Costs: Hidden ROI Factors in Solar Storage Systems

Understanding ROI in Solar Storage Systems

When talking about ROI (Return on Investment) in solar systems, it’s essential to look beyond initial costs to see the full picture.

The basic formula for ROI is:

However, solar energy storage systems have hidden benefits that can enhance this calculation significantly.

Long-Term Savings Beyond Purchase Price

With competitive price and timely delivery, SolarEast sincerely hope to be your supplier and partner.

FAQs About Beyond Initial Costs: Hidden ROI Factors in Solar Storage Systems

1. How do I calculate the ROI for my solar storage system?

To calculate ROI, consider your initial investment, savings on electricity bills, incentives received and any increase in property value over time.

2. What types of solar storage systems are available?

Common types include lithium-ion batteries, lead-acid batteries, and flow batteries. Each has its pros and cons regarding cost, efficiency, and lifespan.

3. How long do solar storage systems last?

Most lithium-ion batteries last 10 to 15 years, while lead-acid batteries typically last around 5 to 7 years.

4. Are there maintenance costs associated with solar storage systems?

While maintenance costs are generally low, it's essential to budget for periodic inspections and potential battery replacements over time.

5. Can I install a solar storage system without existing solar panels?
