  2. Reduces Electricity Bill.
  3. Use of Open Space for producing Energy.
  4. Payback Period is about years.
  5. Preventing carbon emission to our atmosphere
  6. Annual saving of coal.
  7. Annual Saving of precious water.
  8. Adds to Green Power Generation. 
  9. Preventing the environment degradation.
  10. Savings in electrical line or T & D losses .
  11. Contribute to solar capacity addition even by small individual consumers  and thus leading to energy security.
  12. Utilizing the available solar energy resource in the State.
  13. Reduces line load, transmission & distribution losses.
  14. To contribute to productive utilization of available rooftop space.
  1. Environmental and Social benefits:
  1. 1.50 Tones of annual carbon emission to our atmosphere will be prevented with the  installation of 1 KW capacity Solar Power Plant.
  2. There will be an annual saving of approx. 1.26 M.Ton of coal if 1 KW capacity Solar Power Plant is installed.
  3. 8.30 K.Litres of precious water will annually be saved on installation of 1 KW capacity Solar Power Plant which gets consumed in generating equal quantity of electricity through a Thermal Power Plant.
  4. Adds to Green Power Generation. 
  5. Preventing the environment degradation due to large hydro – stations: Due  to  construction  of big  hydroelectric  dams,  productive  land  &  forest  gets submerged & destroyed and  large no. of people have to be rehabilitated posing serious & grave problems.  This further causes  numerous  environmental  issues  which many a time become  an  impediment  to the execution of  the  project  and  cause  delays. SPV power plants create no such issues and hence are perfectly ‘people friendly’ technology.
  6. Offset  the  need  for  setting  up  a  coal  based  thermal power station
  7. Large scale use of solar power in India can produce substantial reductions in green house gas emissions, particularly carbon dioxide.

 

  1. Benefits to the Power Utilities:
  1. Savings in electrical line losses: substantial Energy is lost in the transmission of power to customers due to the electrical impedance in the T&D system. If the total load doubles in the given system the losses increase by about four times. A PV Generating system being located on the consumer end itself, total power so generated comes to wholesome utilization with no  T & D losses.
  2. Voltage Support: The PV system can reduce the power drawn from Electricity Department grid and reduces the voltage drop. This helps when large power is consumed by air-conditioners and irrigation pumps from the grid (during switching on such loads the voltage dip may take place). In rural remote locations, at the end of the distribution systems where the voltages are known to be very low due to over  loading and under sized grids, the solar power generating system would provide voltage support to the grid.
  3. The quantum of electricity consumed by eligible consumer, who is not defined as obligated entity, from the solar photovoltaic power plant may qualify as deemed Renewable Purchase Obligation (RPO) for the distribution Licensee.
  1. Benefits to the State:
  1. To contribute to solar capacity addition even by small individual consumers  and thus leading to energy security.
  2. To optimally utilize the available solar energy resource in the State.
  3. To help in reducing line load & transmission & distribution losses.
  4. To contribute to productive utilization of available rooftop space.
  5. To create public awareness and environment consciousness amongst the citizens.

The nodal point of contact for technical help for installation of Solar Power Plant is the office of Addl. Deputy Commissioner-cum Chief Project Officer at district level and the Director, Renewable Energy Department/HAREDA at state level.

  1. What are the types of solar cells / technology?

Mainly the solar cells are of three types: (i)  Monocrystalline; (ii) Polycrystalline and (iii) Thin film/ amorphous.

  1. What is the difference between monocrystalline, polycrystalline and thin film PV panels?

Monocrystalline solar panels tend to be slightly more expensive than polycrystalline panels, however monocrystalline panels are having a higher efficiency than others. The degradation level is more in case of Thin film solar cells.

  1. How much do the solar PV panels weigh?

Normally weight of a 250 Watt panel/Module about 22-26 kg.

  1. Are the solar PV panels fragile?

Solar PV panels are very robust and can withstand the normal stresses subjected by nature.

  1. What is an inverter or Power Conditioning Unit (PCU)?

There are two kinds of electricity, DC and AC. Homes that are connected to utility power use AC electricity. Flashlights, small radios and automobiles use DC electricity. In order to use solar power to operate the appliances in your home, an inverter will convert solar  power from DC to AC. Inverters can be further classified as units that use batteries and those that use the utility grid as power storage (Grid-connected). For grid connected solar power plants with battery bank, Power Conditioning Unit (PCU) is required having various features, while for system without battery bank shall require inverter. 

  1. Who are the Vendors for installation of the system?

Approved Channel Partners of MNRE or Manufacturer/Supplier/System Integrator empanelled with MNRE are the vendors for installation of the system. While Renewable Energy Department, Haryana/ HAREDA is the state nodal agency for installation of the system. List of Channel Partners/Entrepreneurs empanelled by MNRE is available on the website www.mnre.gov.in and alos on www.hareda.gov.in

  1. Are there any technical standards for various components of the system?

Yes, the various components of SPV system shall have IEC/ISI/BIS Certification and confirm to technical standards specified by MNRE/HAREDA. Detailed technical standards for various components of the system are given on the website of HAREDA www.hareda.gov.in.

  1.    What are the advantages and Limitations of Solar Power Plant?

Advantages/Disadvantages  of  A  Hybrid  System (Grid Connected with battery bank):

Advantages:

  • High level of reliability to Battery bank.
  • Lesser battery discharge and hence longer life of battery.
  • Reduced electricity bills.
  • Highly reliable system and can be used in wide range of URBAN/Industrial/Institutional application.
  •  Also improves the quality of AC power and can be called solar UPS.

 

Disadvantages/Limitations:

  • High Cost.
  • High cost on maintenance
  • Works on battery charge-discharge leadings to:
    • Wastage of precious PV power generated.
    • Reduced battery life.
  • Does not ensure optimum yield from PV panels.

Thus Hybrid Solar Power Plant is suitable only for RURAL areas where Electricity Power from the Grid is not available at present and is not likely in near future.

 

Advantages/Disadvantages of Grid-Connected Power Plant without battery bank:

Advantages:

  • High conversion efficiency of PV Power into usable AC power
  • Simple system with longer life i.e. no battery life issue.

Disadvantages:         

  • Works only when grid power is available.
