84kW Solar System Price in India, 2022

With changing lifestyles and rising level of affluence, there has been a change in people’s way of life and living conditions. Today, people can live in houses as fancy as a bungalow, a farmhouse, a smart home or in residential complexes and apartments. People who are financially well-off and prefer comforts and conveniences in life are making a shift to smart homes. A smart home as the name suggests, has many smart appliances that work on Artificial Intelligence making lives of its residents easier. Most of these appliances can also be monitored through smartphones.

  • Working time: 8 - 9 hours/day
  • Total time: Up to 2 months for paperwork and inspections
  • Skill level: Advanced
  • Project cost: ₹50,40,000 for materials and labor

  • Similar to the concept of smart and luxury homes are Green buildings. Green buildings are energy efficient, self-sustainable, and less polluting buildings. Planting green plants on terraces, balconies, and rooftops could also go a long way in reducing heat and cooling the surroundings. The Indian government is also promoting these buildings so as to reduce the overall carbon emission in our country, with many states undertaking measures like reducing property taxes and stamp duties, providing subsidies on capital investments, etc.

    1. Project Summary

    84kw solar system

    Recently, Loom Solar panels were installed on a green building rooftop in Hyderabad city centre. This terrace garden has huge open space having a party area, gym, pool, theatre, joggers’ track, etc. It is a seven storeyed building with lot of greenery all around. The lights on terraces are solar garden lights which uses solar energy in the day and automatically lights up at night fall.

    2. Engineer Visit

    engineer visit

    Since this was a different kind of project with customized requirement an engineer visit was a must. Please note we highly recommend engineer visit in all cases before installing solar systems. Remember, solar system is an expensive investment and it makes sense to take professional help since technicians are more knowledgeable about latest technology, your requirements, budgeting, spacing, installation, etc. and are better positioned to guide you on the same.

    3. Solar Quotation

    solar quotes

    The average electricity bill cost per unit ranges from Rs. 5.50 to Rs. 12 in this area. In comparison, the average cost of solar is 60K/ kW in this case and is capable of saving Rs. 1,000/ kW in electricity bills monthly.

    4. Design of Solar Power Plant

    solar system design

    After Engineer visit, the whole plan was designed keeping in mind the customer’s requirement of using solar but leaving enough space/ area for people to freely move as well as even jog. In order to utilize space smartly, solar panels were installed on elevated tables/ platforms to enable the flow of air and movement freely. The elevated structure is made up of MS Steel, 16 feet in height and 3 mm in thickness. An 84 kW solar system has been installed on the rooftop.

    5. Feasibility Report

    feasibility report

    A feasibility report is required to get approval for net metering. It comprises of all details regarding the solar plant, the number of panels, the power wattage, the requirement whether commercial or residential, address of installation, owner, installer details, etc.

    6. Bill of Materials

    solar system components

    Here is a list of all components of the 84 kW solar system with details like
    number, wattage, etc. which will help any person form an idea of what goes in the whole installation – solar panels (SHARK bifacial mono-perc), solar stands, solar inverters, electric meters, net meters, BoS, etc.

    1 Solar Panels
    SHARK Bi-Facial Solar Panel, 440 - 530 Watt * 128 & SHARK 540 - 38
    2. Solar Inverter 71kW, 3 Phase

    6. MC4 Connectors -
    7. Earthing Kit -
    8. Lighting Arrester -
    9. Net Meter 3 Phase Meter

    7. Tools

    solar tools

    For such a huge project you would definitely need tools to help in installation. These tools include nut bolts, tape, ladder, etc.

    • Tape measure
    • Pencil or marker
    • Drill with bits
    • Chalk line
    • Wrench set
    • Screwdrivers
    • Metal cutting saw
    • Electrical wiring tools

    8. Solar Panel Cleaning

    solar panel cleaning

    Solar panels’ efficiency is improved manifold when the surface of the panels is clean. If there is dust accumulated on the surface, the working of the panels is hampered. So, in order to generate more power, solar panels must be squeaky clean. You can either employ people to manually clean the panels, or you can use a special coating on panels which avoids any dust to stick on the surface and allows dust to sweep away on its own with wind, or you can also install automatic bot cleaning. The auto-bot cleaning is expensive but you can set alarms for it to clean at times when there is no sun, to allow the panels to generate power incessantly.

    9. Net metering

    net metering

    After taking feasibility approval, net meter can be installed wherein any excess power generated by the system can be sent back to the grid to claim credit.

    10. Benefits

    solar system benefits

    The 84 kW solar rooftop system is capable of generating 30 lakh units of electricity, saving 1400 tons of carbon dioxide and is equivalent to planting 2,200-2,300 trees in its full lifetime. SHARK bifacial mono-perc (22% efficient) solar panels have been used in this installation. Not only are they eco-friendly but also go a long way in reducing your power bills and promoting plantation of more green plants.

    11. ROI

    The ROI is expected to be 4-5 years. The RoI indicates the time period within which you are able to fully realize your investments. Post this all that you have is SAVINGS!!

    12. Solar Finance

    solar finance

    The value of newly constructed buildings having solar system installed also increases with time as it is not only a technology for gen-next but also makes electricity bills practically as zero for its residents. It is important to decide the time of installing solar as a person who is looking at investing in a new property can claim the cost of solar plant as total property cost. A person who is ready to pay Rs.1 Cr for a house can readily pay Rs. 10 lakh more if aware of its advantages.

      Conclusion

      With real estate reaching sky-high prices, many societies cannot afford to have gardens for recreation purposes. Most building now have rooftop terrace gardens housing most facilities as most big gardens. Though it might be compact in nature, but given the paucity of real estate area rooftop gardens are gaining huge importance in big cities. However, given the rising number of facilities used in these terrace gardens the electricity requirement will also be high in such buildings. Hence, using solar panels makes complete sense not only environmentally but also economically.
