Awareness of Solar Installations

  • +    What is a Solar Power Plant?
  • A solar power plant is a combination of multiple components such as PV modules, Inverters, sub structure, Battery, Bi-directional meter, clubbed together to generate electricity from Sun.
  • +    How does it Work?
  • It works on the principle of Photo-voltaic, where the light of sun falls perpendicular to the surface of the PV panel and the photo-voltaic cells in the PV panel gets charged from the sun rays and generate electricity.
  • +    What types of solar PV systems are there in the market presently?
  • Solar PV systems are of 3 types viz. a] On-grid b] Off-grid c] Hybrid
  • +    What is an On-grid solar system?
  • An on-grid solar system works along with the reference of the grid where the solar generated electricity is fed to the consumer’s distribution panel along with the existing grid’s electricity. In such types of systems any shortfall from Solar is compensated [termed as imported from grid] by electricity from the grid and in case of excess generation of electricity, it is fed to the grid [termed as exported to the grid]. A bidirectional meter is installed at the point of distribution panel to keep a record of imported and exported unit. At the end of the month and the consumer is billed on the net units consumed [imported unit-exported unit].
  • +    Can an On-grid plant run if there is no electricity supply from the grid?
  • No, a solar power plant cannot function if there is no electricity supply from the grid.
  • +    Does the Govt support installation of Solar system?? Is the On-grid facility available in the state of Maharashtra??
    1. Yes, the Govt of India is encouraging consumers to opt for using solar power and has even setup ambitious targets to achieve in its solar policy known as Jawaharlal Nehru National Solar Mission [JNNSM]. On-grid facility is available in the state of Maharashtra, the whole frame work of its implementation and regulations are formed by Maharashtra Electricity Regulatory Commission [MERC] and the policy is called as Maharashtra State Net Metering Policy. This policy was launched in the year 2015.
  • +    Can we run high consumption appliances such as A.C, refrigerators or Machineries such as Lifts, water pumps etc on Solar Power??
  • Yes, we can run such appliances and machineries on solar power since it is backed by the power supply from grid. Hence, any shortfall would be sufficed from the grid without the consumer experiencing any kinds of fluctuations in the functioning of the devices.

  • +    How much electricity does a solar power plant generates in a year
  • A 1 kWp [kilo-Watt peak] generates about 1400 kW-hr [units] of electricity per annum
  • +    Where are solar power plants installed? How much space do they require?
  • A solar power plant can be installed only on the roof where there is availability of shadow free space. 1 kWp of solar power plant requires about 80 sft of shadow free space
  • +    Who all can get a solar power plant installed?
  • All type of consumers who have shadow free space available on the roof can install a solar power plant. Categories such as Industrial, commercial, social, education, hospitals, hotels and residential can avail benefits of solar power.
  • +    How can a residential building where multiple flats are there, benefit from solar power??
  • In a residential building, a consumer can install solar power plant for its common consumption such as lifts, water pumps, passage lights, club house etc.
  • +    What are operational and maintenance cost of a solar power plant?
  • A solar power plant has almost zero operational & maintenance cost, as only activity required for maintenance is periodic cleaning of PV modules with water and mops.
  • +    What is the weight of 1 solar panel?
  • Weight of one solar panel is 22 kgs.
  • +    How much time does it takes to install a solar power plant?
  • A general timeline for completion of a project in solar industry is 10-12 weeks (along with net meter), where as actual installation time required for setup is 15-20 working days on the site. A higher timeline is given as net meter liasoning process takes time for completion.
  • +    How would I know if my plant is functioning properly?
  • A solar power plant comes with monitoring systems which informs us of live generation on our PCs and cell phones through apps. A user can see daily generation; saving and also get alerts if there are any issues with the plant for rectification.
  • +    What would be my payback period of investment done on installation of solar power plant?
  • Payback period of return on investment is 3-5years. A solar power plant comes with a generation guaranteed for 25 years, hence a consumer recovers its cost of installation within 3-5 years and gains access to free electricity for remaining 20 years.
  • +    Are bank loans available for installation of solar power plant?
  • Yes, bank loans are available on installation of solar power plant. In fact there are special interest rates made available for consumers who are opting to install solar power plant.
  • +    Do I require to take special permissions from municipality for installation of solar plant
  • No special permissions are required to be taken from municipality. Only permission required is from the Discom for net meter connection.
  • +    No special permissions are required to be taken from municipality. Only permission required is from the Discom for net meter connection.
  • • To collect electricity bill of the consumer for analysis of the load and plant size requirement.
    • To conduct reconnaissance survey of the site, analyse the feasibility of the installation location and space availability.
    • Prepare techno-commercial feasibility report of the solar power plant.
    • Design of solar power plant.
    • Demarcation and civil foundation work on site.
    • Erection of Super structure for module mounting
    • Placing of PV modules on the super structure
    • Electrical side connection of the plant and its commissioning.
    • Net meter liasnoning procedures.
    • Provide technical details to the DISCOM to facilitate net metering process.
    • Collection and submission of required documents to DISCOM for net metering process.
    • Operate and maintain the plant after installation.
    • Train and guide the consumer on operation and maintenance of the plant.
    • Provide after sales support and keep a check on the generation of the plant on a regular basis.
