How and Why Solar Energy (PV Solar) scores over other Renew Techs?

There is a lot of interest generated lately in Green Energy or Renewable Energy Sources. This interest may seem sudden but in fact the interest had always been there just that it is becoming visible now. Everyone was keen to tap Solar Energy - in someway or the other to make use of the same as part of day-to-day activities. For all practical purposes one can consider The Sun to be practically infinite source of energy thereby drawing a lot of attention.

Renewable Energy Sources are especially important in the Indian context because of large-scale dependence on Fossil Fuel especially Coal which accounts for nearly 60% of power generation in India. Although there are a variety of renewable power options Solar Energy will contribute maximum to India Growth Story.

Challenges of depletion of fossil fuels, environmental hazards, increasing power demand, infrastructural issues in transmission and distribution etc. are quite well-known. With a present peak power deficit of 10% it is estimated that it would rise to nearly double in the next 5 years unless stringent and concrete measures are taken to meet the power demand. Renewable Energy Sources such as Solar, Wind, Hydro, Tidal, Geothermal play an important role. Any Country must ideally look at its strength in terms of Geographic conditions and allocate suitable budget for the right mix of power portfolio which should have maximum priority to the most easily available and feasible option.

In the Indian context Solar Energy is the leader in terms of Source of Renewable Energy and it offers several advantages in a growing economy. Various factors that work in favor of PV Solar are

  • PV Solar is the only power generator which can deliver power at ZERO operational cost / running cost. No other renewable technology can claim this.
  • Excellent Solar Radiation across the Country ensures feasibility of PV Solar across the Geography.
  • With 25-30 years of critical component life (Photo Voltaic Modules) it ensures a long-term, reliable and sustainable power solution.
  • Generation-Load proximity ensures minimal losses - a very important aspect in a Country which has one of the worst ATC (T&D) losses in the range of 25-30%.
  • PV Solar is truly environmentally friendly with a Energy Payback of 2-5 years which no other renewable energy technology can claim.
  • PV Solar can be installed closed to human habitat as it does not cause any health hazard.
  • PV Solar also has an advantage over Solar Thermal Power - in which it does not require water to operate.
And many more such advantages...

Industries should ideally be the first movers as they can benefit immensely from the units saved as they are charged a higher power tariff. In fact several leading Industries have already taken the first step in this direction by carrying out feasibility study at their sites and results have been phenomenal. On an average any industry can reduce around 10% of its power consumption and also benefit from several Government subsidies under JNNSM.

Apart from general awareness on the subject the problem with PV Solar is Myths surrounding it. However with the percolation of appropriate information we expect that PV Solar will become the solution of choice at not only Industrial or Utility level but also at household level.


  1. Solar PV should be promoted at household level with a clear cut policy, training & mandatory from central & state GOVT.

    1. Dear Sir,

      Yes, you are right about promotion of Solar for household. This is becoming more viable with falling price of Solar. An awareness is the need of the hour and we are doing our bit by offering Solar Energy Online training courses which could be attended from anywhere.
