Understanding Savings on Solar Energy: In-depth analysis.

by with One Comment Blog

Figure here is a graphical representation of comparison between expenditure/earning on electricity consumption with or without Solar Installation.

SAVINGS WITH SOLAR

We have compared a case of one consumer spending money on installation of solar rooftop power plant on his roof and generated solar energy offsets some of his electricity bill and the rest of the bill he pay from his pocket and another consumer who invests equal amount of money at interest rate of 8% per annum and pays his bills out of this corpus monthly instead of spending money on installation of solar energy. Example shown above is for installation of 3kW Solar Rooftop Plant without considering subsidies. Comparison is drawn of financial journey for a period of 300 months (or 25 years -accepted lifespan of solar panels) duly accounting for drop in efficiency of generation with time.

Explaining the Financial Journey

Case-A (without switching to solar energy)

Cost of installation in above example for a 3kW solar power rooftop plant is take as 1.80 L. Hence consumer A starts his journey with positive corpus of 1.8L in his hand and invests this money for an annual return of 8% and continues to pay his monthly bill of 350 units per month from his pocket. His journey is represented by Green Line in the graph where his corpus continues to fall for 25 years. His total spent on this journey is about 14L in addition to his initial corpus of the  1.8L. 

Case-B (After switching to solar energy)

Consumer-B utilizes that same initial corpus of 1.8L for installation of Solar Power System on his roof. Assuming that person is living in Gwalior, Madhya Pradesh average energy generation is 4 units of power per day per 1kW of solar capacity installation. Hence his daily power generation is 12 units resulting in monthly power generation of 360 units. This is about the same capacity as his average monthly electricity bill. Consumer-B has to pay electricity charges after some years due to drop in efficiency of solar panels which has been taken into account. He has to pay overall about 4L including his initial cost of solar installation His financial journey is represented by Yellow Line in the graph.

Conclusion

As it is apparent from the comparison above, consumer-B had to spend a lol less to meet his electricity requirement throughout the period of 25 years. His Savings are represented by Orange Line on the graph leading to a total savings of more than 10L during this period. He managed to save a huge amount of money in terms of energy consumption in addition to doing something for the environment. He manages to offset 4kg of CO2 emission on every 1 unit of electricity generated by solar panels. Become a wiser consumer with installation of solar installation on your rooftop and save huge amounts of money.

However before installing solar Rooftop systems on your home, you must ask all the doubts you have in your mind before finalizing your installer. Here are some crucial enquiries you must have answers to before embarking on solar powered journey of free electricity- 

      1. What experience do you have in solar installation?
      2. Can you provide references or examples of past projects similar to mine?
      3. What solar panel brands do you recommend, and why?
      4. How do you handle permits and approvals for solar installations?
      5. What warranties do you offer on the solar panels and installation work?
      6. Can you assess my property's solar potential and provide an estimate of energy production?
      7. What financing options do you offer, and can you help with the process?
      8. How do you handle maintenance and repairs after installation?
      9. Do you offer monitoring services to track the performance of the solar system?
      10. What is your timeline for installation, and how do you handle unexpected delays?
      11. How do you ensure the safety of your installation crew and my property during the installation process?
      12. What happens if my energy needs change in the future? Can the system be easily expanded or modified?
      13. How do you handle shading issues that might affect solar panel efficiency?
      14. Can you provide a detailed breakdown of the costs involved in the installation, including any potential additional fees?
      15. What post-installation support and customer service do you provide?

      If you are opting for more aesthetically pleasing and multipurpose installation such as a hut or covered area with elevated structure. 

      You must ask your installer if the structure that is being built is properly designed by engineer to withstand various loads during its lifetime. What material is being used for installation. Given that most guidelines insist upon mounting structure of HDGI (Hot Dipped Galvanized Iron) so as to prevent corrosion and lighter weight of the structure. Generally speaking, total weight of such structure should not exceed 60-70 kg per meter square. Any solar structure and panel installed on your roof is going to last for more than 20 years, which is a very long period. Steps need to be taken at the time of installation itself to ensure longevity of that structure. 

      Various other aspects also need to be kept in mind such as change in energy needs, scope of expansion, ease of replacement etc.

      3 things you need to know about solar financing in India.

      by with 3 Comments Blog

      Know more about solar financing.

      Solar financing is easier way of getting started with solar energy without delay, let's discuss key aspects -

      Switching to solar energy can be a big step for Indian homeowners, but the initial cost often holds many back. According to a survey, the main reason people hesitate to go solar is because it can be expensive upfront. But there's good news! There are ways to finance solar panels that can make it easier for you to make the switch and start saving money on your energy bills.

      First, let's talk about buying solar panels with cash. This means you pay for the panels all at once, without taking out a loan. It's great because you don't have to worry about paying interest, and you can take advantage of tax credits and other benefits. But for many people, coming up with the money to buy solar panels outright is tough.

      That's where solar loans come in. These work like any other loan—you borrow money from a lender to pay for the panels, then pay it back over time. There are different kinds of solar loans, some where your home is used as collateral and others where it's not. The downside is that you'll have to pay interest, but the good part is you'll own the panels and can get tax credits.

      Another option is a cash-out refinance or a Home Equity Line of Credit (HELOC). With these, you borrow against the equity in your home to pay for the solar panels. They can have lower interest rates than other loans, but if you can't pay them back, you could lose your home.

      Lastly, there are solar leases and Power Purchase Agreements (PPAs). These are like renting solar panels instead of buying them. You pay a monthly fee to use the panels, and the company that owns them takes care of maintenance. The downside is you don't get tax credits, and you might have to pay fees if you want to end the lease early.

      So, which option is best for you? It depends on your budget and how long you plan to stay in your home. If you can afford it, buying solar panels with cash is usually the best choice. But if you need to finance, look at all your options carefully and choose the one that works best for you.

      Switching to solar energy is a great way to save money and help the environment. With the right financing option, it's easier than ever to make the switch and start enjoying the benefits of solar power!

      You can also switch to solar with solar loan, contact us for consultation and we will guide you through the entire process.

      How to determine capacity of Rooftop Solar Installation required for my house/ business?

      by with 2 Comments Blog

      What capacity of rooftop solar you need to completely offset your daily electricity consumption?

      We have tried to explain in simple terms, how the output of Solar Installation is calculated and produces a general guide to help consumers determine required capacity of rooftop solar for their home -

      Centrally located Madhya Pradesh (MP) is the second largest (308.25 km2) and the sixth most populated Indian state (72 million as per Census, 2011). The average annual per capita power consumption of MP is 739 units against the Indian average of 1010 units (both 2015 values). The average annual per capita income was Rupees 56,182 against the Indian average of Rupees 103,219 in 2016–17. MP has high solar potential of 300 days of sunshine along with high solar insolation of 5.5 kWh/m2/day.

      If you are an average middle class household in Madhya Pradesh then potentially your monthly electricity consumption is not more than 739 units i.e. 739kWh per month. 

      Assuming your monthly electricity consumption is 750 kWh then you need to install about the same capacity of a solar power plant so that it completely offsets your entire energy consumption for the year. Now, as per statistical data, Madhya Pradesh receives about 300 days of sunshine in a year along with high solar insolation of 5.5kWh/m2/day. 

      Let’s calculate the yearly consumption of your household i.e. 750 kWh per month X 12 month per year = 9000 kWh per year or 9000 units per year.

      Assuming you have done your fair share of research and know about different types of solar PV Modules available in the market, you know that Monocrystalline PV Modules are high efficient modules used for domestic rooftop or small commercial rooftop systems. These modules have efficiency of 18-21 %. 

      Let’s be conservative here and assume that the solar PV Modules are giving you an efficiency of 18% (which is a considerable underestimation for Monocrystalline PV Modules). 

      Total energy that can be generated in a 

      year per m2 of Solar Power Plant = 5.5 kWh/m2/day *300 clear days per year * efficiency

      = 5.5 x 300 x 0.18

      = 297 kWh/m2/year

      Hence, total area that will be required to completely offset your energy consumption will be = 9000/297

      = 30.30 m2

      Hence, capacity of Rooftop Solar Plant = 1 kW/m2 x 30.30 m2 x 0.18 

      = 5.45 kW

      Conclusion: 

       If you are a middle class household with average electricity consumption, all you need to do is install a rooftop solar plant of 5.45 kW capacity to completely offset your energy consumption and boast of not contributing to global warming. 

      To make your task easier, we have produced below a chart for determining the suitable capacity of a rooftop solar power plant/ installation for your home. Just read the value corresponding to your average monthly units of electricity consumption. It is advisable to determine the average electricity consumption by average last 12 month's electricity bills.
