Air Pollution: Hidden Barrier in Solar Energy Growth

Solar Energy

India's accomplishment in turning into a main nation in environmentally friendly power energy transformation inside only several years, demonstrates commendable strategy and support structure built up by the Government of India. Administration has set a target of 100 GW of Solar capacity by 2022. This target is supported by following three approaches:

 

  • Rooftop Solar (40 GW)
  • Ultra-Mega Solar Parks (25/40 GW)
  • Utility Scale Project (35 GW)
Installation of Solar based energy gained momentum in last 3-4 years and the sector is growing at substantial rate. Currently installed capacity of Solar in India is 26 GW (Grid-Connected). India’s installed approx. 23 GW in last three and half years.

However, attracting investments, creating policy environment, and raising awareness to speed up solar adoption rate may not produce results as desired and targeted due to a critical and hidden issue: POLLUTION
 
Pollution: Blocking Solar Growth in Form of Decreased Generation
 
The share of petroleum product in world's energy supply has developed from 6,100 million tons of oil equal (Mtoe) in 1977 to about 14,000 (Mtoe) by 2017. Likewise, it is suspected that worldwide energy related CO2 emanations will increase from 32.3 billion metric tons to 43.2 billion metric tons by 2040, if genuine changes are not actualized. Be that as it may, not simply our future, the present Pollution level is rapidly turning into a noteworthy detour for Solar based development, which can conceivably enhance the energy situation in future. To restore the significance of environmentally friendly power energy change, we should feature that 1 kW of efficient power energy can diminish in excess of 3,000 pounds of CO2 yearly. What's more, Countries like Japan as of now have recorded 0.4%/year decrease in CO2 discharge through Solar based appropriation.
 
India is unmistakably strolling on a similar way towards environmentally friendly power energy progress, endeavoring to stage our petroleum derivative and cut Pollution levels. Be that as it may, the persistently corrupting Pollution levels are acting like a danger to Solar powered development in India.
 
In Northern regions of India, rising dust and particulate matter (PM) have decreased the energy yield of solar oriented plants by 17-25%. The dust and particulate matter make a divider between beams from the Solar radiation and the Solar modules, contracting down the energy age limit. A valid example is decrease in Solar energy output of Solar modules in Delhi, which remain at 12% every year (from 2017). This decrease in energy return is bigger than the net revenues of certain establishments. Lost incomes from Solar energy output of Solar modules in Delhi alone stands at $20 million every year. In Kolkata (another city in India), the loss of income remains at $16 million.
 
Comparative occurrences were found in Baghdad, Singapore and different states/urban areas around the globe where air Pollution has brought about 15-25% Solar powered energy yield loses.
 
Solar Sector Need to Perform to Succeed
Solar based energy reaping and use is not another innovation, its overall acknowledgment as the future standard energy source is somewhat new. And in order to become the mainstream energy supply source, Solar power needs to fulfill quickly developing energy request in (India's energy utilization is relied upon to develop by 4.2% P.A) and the world (Global energy request developed by 2.1% in 2017). Despite developing innovation that is expanding, PV module's energy collecting productivity and falling Solar Panels cost can't fulfil the interest if the surrounding Pollution obstruction hinders the sunrays.
 
In this manner, obviously expanding surrounding Pollution remains as an undeniable risk to Solar oriented selections in India.
 
Way Forward
Pollution isn't just a developing danger to our condition; it is additionally backing off Solar power development, which remains as the best defensive measure against contamination. It is imperative to bring up that, an ongoing report The Centre for Policy Research and International Institute for Applied Systems Analysis featured that, despite the fact that India's CO2 outflow from energy Generation is expected to double in 2030 from its 2012's discharge figures, the dimension of Pollution will at present be under broadly decided (in Paris Agreement level) CO2 emanation.
 
In any case, as present Pollution level is now managing a harming hit to solar-based energy reaping execution, the Government of India needs to take broad measures to increment Solar based development. Frequently cleaning the panels, wiping out the barrier created of fine dust particles must be undertaken. But, more importantly, focusing on auctioning more projects, stabilizing solar tariff, exempting SEZ based solar manufacturers from 25% safeguard duty, enforcing RPO targets, discouraging states from re-negotiating PPAs, and reducing solar module imports to build domestic manufacturing excellence is desperately needed. Expanding Solar power reception rate massively inside India and explaining issues inside the solar panel projects establishment procedures would assist India with outpacing Pollution and keep up energy and ecological soundness.
