Interpreting the EnerMark solar project returns report


This post is intended to describe how to interpret a solar project report generated by the EnerMark estimator. The report is generated when a user estimates project returns by accessing How much Money you can make by installing solar on the EnerMark homepage. If you are interested in knowing more about the actual procedure to generate a project report, click on our previous blog post here.

An example project report is shown in the image below:


Next, I will discuss in detail how to interpret the numbers and graphs shown in various sections of the report. So, lets get started.


1. Return on Investment

This section provides information on the return on investment that one can expect from the solar installation being evaluated.

Specifically the following numbers are provided:

Yearly income/savings is derived by adding up each month’s monetary value for the electricity produced (for detailed explanation, please scroll below to Monthly Electricity Generation section).

Time to recoup initial investment denotes the total time (in number of years) that it will take for an installation to generate enough income/savings to cover the initial investment.

Finally, the Rate of Return, the magic number. This denotes the annual rate of return that can be expected from the solar installation in question. The typical rate of return for an EnerMark project is more than 20%, and many projects even have returns of 46% or more as shown in the picture above .

2. Monthly Electricity Generation

This section denotes the monthly energy produced both in terms of units of electricity produced (KWH) and also the equivalent Rupee amount.

The black bars denote the units (KWH) of electricity produced by the system, whereas the green bars show the corresponding rupee value of the electricity produced, in a particular month. Having month by month value available to you can help you take more informed decision about the size of system needed. And this level of detail and accuracy is only possible through EnerMark proprietary analytics, which no other service provider in India can provide.

The rupee value is calculated based on the unit price of electricity (Rs/KWH) provided by the user. As an example, if in a month 3000 units of energy are estimated to be produced and the cost per KWH is Rs. 9, then the monetary value would be Rs. 27000 (3000x9). Please note that the numbers shown in the graph are rounded to nearest whole numbers for ease of interpretation. 

3. Cost & Specification

This section lists the broad cost and installation specifications for the project

  • Total area: this is the installation area detail of the Solar project provided by the user.
  • Panel area: depending on the geographical location of the project, a suitable amount of space has to be provided between panels; as such the actual panel area is almost always less than the total area provided. The EnerMark estimator makes the calculations needed to provide effective panel area for your location.
  • Initial cost, Subsidies and Cost after Subsidy: these sections provide estimates for the cost of the project and also any subsidies (both at the national and regional level) that may be applicable for your project. Cost after accounting for subsidies is also provided.

It is worth noting here, that we spend a lot of effort in ensuring the accuracy of our analytic models. However, the results shown in the report are also very dependent on the data entered by the user. So, please be very careful about the details you provide (please click here on our blog post to understand the correct procedure to evaluate project returns.)

We also emphasize that if after seeing the report you are convinced that solar is for you, then avail our free on-site project evaluation service. We guarantee project return estimates provided after on-site assessment


4. Cost Breakdown

This section details the cost in terms of various components of the system that need to be installed, as part of  the project.

The cost estimate is broken into:

  • Panels: estimated cost of the actual solar panels to be installed. 
  • Rest of system: this is the estimated cost of other system components such as wiring, inverter etc.
  • Installation: this covers the installation cost, such as labour etc.

Please note that very specific project requirements may result in additional/different system components and these project specific details are covered as part of our on-site assessment. At EnerMark, we strive hard to ensure quality of panels and other hardware. After all, as part of our guarantee, we pay you if the components don't perform as estimated.


5. Monthly Electricity Production vs Usage

This section details the monthly electricity production and compares it with monthly usage, that is provided by the user while entering project details. 

The black bars denote estimated units (KWH) of electricity produced by the system, whereas the blue bars show corresponding usage of electricity, in a particular month. Again, having information by month available, can help you take more informed decision about the size of the system needed. And you don't spend more than what is needed. In fact, EnerMark installed systems cost 20-25% less than comparable systems for the same financial return produced.

The final number in this section is the percentage of yearly electricity requirement met by the solar energy system being considered.

P.S.: The yearly electricity requirement met information and correct graphical representation is shown only if the user enters the monthly usage data while providing project details. If not entered, the graph will only show estimated electricity produced. Hence, it is very helpful to enter electricity usage data, if it is applicable in your case. 


6. Monthly Power Cut Reduction 

If you share similar beliefs then you will agree that in this day and age, it is almost a crime that people still suffer from power cuts in our country. This section outlines a significant information, how close to ZERO POWER CUTS! you can get with your new solar energy system.

The EnerMark estimator takes into account the daily power cut data provided by the user and compares it against the estimated electricity generated by the solar energy system being evaluated. And the estimated before and after power cuts (in hours per day) are shown graphically in this section.

P.S.: The monthly power cut reduction graph is shown only if the user enters monthly power cut data while providing project related information. If not entered, this graph will not be shown. Hence, if one of your goals for installing solar is to eliminate power cuts, then do provide your current power cut information for getting estimated power cut reduction information in the report. 


7. Ideal System Size

Using our proprietary analytics, we can also calculate ideal system size for your needs. This is based on usage and power cut information you provide. This information is included in our on-site assessment. This is a free service, so contact us right away using the contact information given on contact us page of the site. Even better, let us know you are interested as part of the report under Next Steps section (details below) and we will reach out to you.


8. Other Incentives

This section provides any other government, service provider or even EnerMark special incentives that may be applicable to your project. 


8. Next Steps

Although, not really part of the report, but this definitely is the most important section. Full transparency is good business strategy, is one of the core values around which EnerMark was founded. In the results report, we share estimates from the same analytic tools that we will be using to evaluate the project. So, after seeing the report, if you are convinced about installing solar, we will provide complete Solar as a Service model to cater to any next step you choose to take. We will briefly talk about the options here and our up-coming posts will cover each of these in detail:
