Empirical approach shows PV is getting cheaper
Self-generated solar power is already cheaper than grid electricity almost everywhere, making home solar systems economically attractive. Solar
With equated payment loan, the levelized generation cost of solar PV electricity in base year is 28.92 ¢/kWh and it remains same up to 30th year. However, for graduated payment loan with 4% escalation in loan installments, the generation cost of solar PV electricity varies from 17.33 ¢/kWh in base year to 54.06 ¢/kWh in 30th year.
So, in this case, the realistic current generation cost of SPV electricity is 9.51 ¢/kWh and not 28.92 ¢/kWh. Further, with graduated payment loan, extension in loan period results in sharp decline in cost of SPV electricity in base year. Hence, a policy change is required regarding the loan repayment method.
These results bring out the effect of graduated payment loan on the generation cost of solar PV electricity in different years. With equated payment loan, the levelized generation cost of solar PV electricity in base year is 28.92 ¢/kWh and it remains same up to 30th year.
Conservative estimates indicate the result would be a consistent solar energy generation cost of less than $0.02/kWh in central Europe and below $0.01/kWh in Southern Europe and the southern United States. Our empirical modelling is characterized by transparent, comprehensible assumptions and lower complexity than the dominant approach.
Photovoltaic power plants undercut production costs of around $0.01/kWh in 2020, in sunny regions, and the current PV price trend enables even lower production costs. The average costs shown in the Bloomberg chart above could be significantly undercut with new systems.
Self-generated solar power is already cheaper than grid electricity almost everywhere, making home solar systems economically attractive. Solar module prices have fallen more than 99.8% since 1976. Study of almost 3,000 forecasts has revealed just how unambitious analysts have been in predicting solar panel price declines.
