  • addressed some misconceptions in LCOE calculation for PV
  • economic barrier as primary impediment to RE technology adoption in the society
  • defines clearly the concept of grid parity
  • PV grid parity as a function of local electricity prices, PV system component cost and geographical attribute
  • wrong LCOE reporting, strong effects on decision and policy making processes
  • wide and holistic sensitivity analysis of critical variables for decision making
  • most cost of electricity from other power plants from conventional sources are over estimated due to volatility, administrative duties and or systems upgrade - making electricity cost fixed and higher than actual generation cost
  • LCOE generally exclude risk and financing methods
  • accuracy of assumptions in LCOE estimation very critical to energy technology accurate lifetime assessment
  • PV system over-sizing, inadequate input assumptions and high LCOE estimates
  • main assumptions: discount rate, average system price, system lifetime, degradation and financing method
  • keeping other costs constant results indicates direct proportionality between interest rate and LCOE (i.e. LCOE drops with I.R drop and vice versa)
  • keeping I.R and PV cost constant, LCOE changes along varying diesel prices and GHI.
  • At higher I.R. and same PV cost, LCOE also changes along varying diesel price and GHI. Lower interest rate proves better
