The benefits of adopting solar energy by homeowners are well documented. From saving up to 80% on monthly electricity bills to promoting a sustainable society, going solar has proven to be a wonderful investment for homeowners across the country. Mr Sushil Sharma, a homeowner who decided to go solar with MYSUN in Greater Noida, shared his experience in a video here:

It is for the wide availability of solar energy that the installation of PV rooftop solar systems has grown at an impressive rate in the country, increasing from a capacity of 5 MW in 2010~11, to over 5000 MW in 2019~20.

If you are a homeowner you must have already evaluated the benefits of going solar. Being an expensive purchase decision that you will have to live with for 25-years, it is prudent to do a thorough research before making a move. With this blog post, we will bring forth the answers to 11 crucial questions which you must know before installing solar panels on your residential property. We are sure these answers will make your solar journey easy.

1. Can you meet 100% of your residential power requirement with Solar Energy?

Yes, with a well-engineered solar system, you can generate enough electricity required to meet the complete power requirement of your house. However, there are certain factors that may influence your energy generation capacity otherwise. Factors such as your available shadow-free roof area, your sanctioned load, your power consumption, and the solar policy of your state. Here’s how:

• If the shadow-free area available at your rooftop is less than the area required to install the number of panels needed to meet all your energy needs, then you might have to go for a low capacity solar system. In such a scenario, the electricity generated by your solar system might fall short of your total household requirement.
• Solar policies of most India states confine the installation of residential solar systems to be less than or equal to the sanctioned load, especially in the case of on-grid solar systems. In such a case, if your power requirement is more than your sanctioned load then again with the solar system you install, you might not be able to meet all your energy requirements. The good news is that you can apply for an increment of your sanctioned load with your DISCOM and thereafter install a system size as per your requirement.
• If your household energy consumption increases drastically after you have installed a solar system of a particular size, then again the energy generated by your solar system might fall short. In order to tackle this, you can later increase the size of your solar system keeping a note of your shadow-free roof area, your sanctioned load and your state’s solar policy.

2. How much can solar save you on your residential electricity bills?

For residential power consumers, the monthly savings from solar can be as high as 80% and in some cases even more. However, before you order your solar system you should try to determine your savings in absolute values by as much as possible. The reason being - the savings from solar is relative to the unique energy profile of your home. You can estimate your savings my running the MYSUN Solar calculator and taking a site survey from MYSUN Solar Engineers.

3. Is your house eligible for availing net-metering? If yes, when should you apply for it?

Net-metering is a crucial functionality that increases savings from solar if you go solar with an on-grid or hybrid solar system. It helps you export the surplus electricity generated by your solar system to the grid in exchange for compensation.

Currently, the facility is available for homeowners across all states in India. However, the benefits from it may differ depending on the tariffs laid down by the respective states.

You can apply for net metering both before and after your solar PV system installation. However, for convenience, we suggest you apply for net-metering before the system installation.

4. How much will it cost to install your residential rooftop solar system?

The cost of solar systems has fallen dramatically over the past 10 years. To put it in perspective, a typical 1 KW Solar system which was available for approximately INR 145/Wp in the year 2000 is today available for approximately INR 35/Wp. The final cost however varies depending on the quality of components, the expertise of the solar installer and the scale of the project. Since residential solar systems are smaller in size, the per KW cost tends to be higher compared to commercial/industrial solar systems, given the lower scale of operations. The key here is to not compromise on the quality of the components and the expertise of your installer. Benefits from solar are reaped in 25 years, and you don’t want to have any unpleasant experience for a short term gain. To know the estimated cost of your optimum residential solar system, you can run the MYSUN Solar Calculator here.

5. Is there a way to make the cost of your residential solar system more affordable?

Yes, you have the option to make this cost of solar systems more affordable with the MYSUN Residential Solar Financing Option - The MYSUN Flexi Pay. When you go solar with MYSUN, you can defer the cost of solar in easy monthly instalments. If you would like, you even get to choose a solar loan from numerous MYSUN partner banks at attractive interest rates.

6. How soon will your solar system break even?

With a well-configured residential solar system, you can expect your break-even period to be achieved within 3~4 years. The breakeven period is however dependent on the system size and the DISCOM tariff rate of your state. The point to note here is that since the returns from solar are in the form of savings, the returns are assured. To know your estimated return on investment and payback period you can run the MYSUN Solar Calculator.

7. Is your home rooftop a good candidate for installing solar panels?

Checking the durability of your rooftop is extremely important. Your rooftop should be equipped to withstand the weight of the panels and the mounting structures. If your rooftop is not firm, don’t consider going solar until you have repaired it well. Also, since most houses in India are built too close to each other, it is imperative to check that your rooftop is free from any shadows being cast by nearby buildings/objects.

8. Will you be eligible to claim tax benefits on your residential solar investment?

Currently, there are no tax benefits available for residential power consumers. However, the savings on electricity bills themselves are so significant that the investment is worth going for.

9. Can you shift your residential solar system to a different location?

Yes, you can always uninstall and reinstall your solar system in a new location. However, the attempt made should be a careful one so that no damages are caused. Do check the way to go ahead in detail with your solar installer.

10. Who should you choose to buy your residential solar system from?

Your solar installer will be your partner in crime throughout the 25 years of your solar journey. It is therefore extremely important to choose the right solar installer in whom you can have faith in times of need. The best way to start is by identifying their local and national presence, followed by the expertise of their team, the projects they have commissioned and the reputation they enjoy among their stakeholders. Talk to other homeowners who have gone solar with them. At MYSUN, our team has helped numerous homeowners realize their true potential of solar.

11. How can you ensure the good health of your residential solar system for 25 years?

Ensuring regular service and maintenance is the key. Residential solar systems are considerably smaller in size and can therefore be maintenance by oneself. However, it is suggested to opt for a service and maintenance package as it eliminates the risk involved in the job and ensures timely action. Some other ways to ensure the good health of your solar system is to go for premium quality modules as they are more durable than the regular ones and to opt for solar insurance as it safeguards your system against events like fire, theft and burglary. With MYSUN’s exhaustive operations and maintenance package - the MYSUN Care, homeowners get an option to avail 25-year assured service solution at a minimum payable amount.

This growing significance of the calculator is one of the key reasons why we continue to pay persistent attention to the calculator’s user experience and recently worked on improving it even further. Today, with the help of this blog we hope to bring forth the new upgrades and amazing features which entails all-new MYSUN Solar Calculator.

New Features of the MYSUN Solar Calculator

In addition to the already existing functionality which fetches you your solar savings, optimum system size, required investment, and return on investment, the new features added to the upgraded version of the MYSUN Solar Calculator can be grouped broadly in these three categories:

1.Complete New Interface for a Better User Experience

2. Exclusive Financing Fold for clear comparison of your Financing / Ownership Options

3. A Complementary detailed report for more flexible assessment

1. Complete New UI for a Better User Experience

User experience is critical for gaining affinity towards any product that we use. The upgraded MYSUN Solar Calculator therefore has an improved experience at the core of its build. The new MYSUN Solar Calculator brings several advanced personalization options giving the users a complete control of their solarization requirement. The upgraded version provides you a one-stop destination for all your solar calculations. The neat design groups and divides the features into separate folds making it easy for you to navigate through both - the technical and financial aspects of the output.

First Fold with Basic Features of the MYSUN Solar Calculator

While the first fold displays an easy to comprehend basic assessment of your solar potential, the second fold displays the advanced customizable features, making it easy for you to input the values as per their unique architectural requirement and check the impact of these adjustments on your energy generation, savings and returns from solar. For example, if your rooftop structure is sloping instead of flat, with the new calculator you can now check its impact on your system’s energy generation capacity and thereby your returns from solar. Based on this you can determine if you need to opt for a higher system size to meet your power requirements, given you have sufficient roof area and flexibility to increase the system size as per your sanctioned load and your state’s solar policy.

You can also check your precise solar potential by adjusting the sanctioned load, connection type i.e low tension/ high tension, net-metering preference, available roof area, solar energy consumption and shadow casting objects as per your specific requirement. You can even check your savings from solar as per the orientation of solar modules i.e. east, west, north or south facing. The new MYSUN solar calculator thus, gives you the ability to access your benefits from solar more accurately than before.

Second Fold with Advanced Features of the MYSUN Solar Calculator

2. An Exclusive Financing Fold for Solar Financing Comparisons

The improved MYSUN Solar calculator now carries an exclusive Financing fold to demonstrate the various financing options which you can opt for while going solar. In a well demonstrated comparison between CAPEX(Capital Expenditure), DPA(Deferred Payment Agreement) and PPA(Power Purchase Agreement) models of financing/buying solar, the financing fold illustrates the financial gains that you can be reaping or missing out on by choosing a particular solar financing option.

For example, if you are a commercial category power consumer from Delhi with an average monthly electricity bill of INR 1 Lakh, the calculator shows how your savings from solar will be the highest if you went solar under CAPEX model of buying solar than the DPA or PPA.

The financing fold also shows you the Payback period and the Equity IRR of your solar investment, thereby helping you compare and find your optimum solar financing/buying model as per your financial need/situation. For example, as shown by the calculator below, a commercial business unit from Delhi with an average electricity bill of INR 1 Lakh can expect to earn the payback from its solar investment in 1.9 years in case of CAPEX and 2.2 years in case of DPA. Post this timeframe, the business can enjoy electricity from solar virtually for free.

In addition to these, the financing fold also brings forth what often gets overlooked when choosing an optimum solar buying model, i.e the Levelized Cost of Power to you - the average per unit cost of energy which you will incur in each of these solar financing/buying models in the next 25 years of your solar journey. In the case of the above example, the levelized cost of power for a commercial set up in Delhi with INR 1 Lakh monthly power bill will be the lowest in case of CAPEX followed by DPA, PPA and then the grid electricity:
