Is solar power cheaper than coal?
In the last few years, the cost of gridconnected
solar photovoltaic (PV) power
has come down drastically. There is
strong evidence from international studies
that the levelized cost of solar power
is on par with coal-fired power plants
when the cost of externalities (greenhouse
gas emissions, air pollution and
ash disposal) is taken into account. A
one-day workshop was held recently to
explore how far these cost trends of solar
and coal-fired power plants are valid in
the Indian context. The workshop was
targeted at various players in the power
sector, such as decision-makers, bureaucrats,
think-tanks, power generation and
distribution companies, academic institutes
and grass-root organizations
Performance of a megawatt-scale grid-connected solar photovoltaic power plant in Kolar District in Karnataka
A megawatt scale grid-connected photovoltaic power plant was commissioned on 27 December 2009 in
Yalesandra in Kolar district in Karnataka. The Yalesandra plant is one among more than 20 such Megawatt
size solar power plants in India during the past few years. The performance of this plant during its first
year of operation has been discussed. The total electrical energy generated by the Yelasandra plant during
2010 was 3.34 million kWh. Although the performance of photovoltaic modules was good, there were problems
associated with the inverters which led to reduction in energy generation. The impact of temperature
variation of modules on their performance has been highlighted
