Solar power generation is not cost-effective

Power generation from renewable energy technologies is increasingly competitive, despite fossil fuel prices returning closer to the historical cost range. The most dramatic decline has been seen for solar PV generation; the LCOE of solar PV was 56% less than the weighted average fossil fuel-fired alternatives in 2023, having been 414% more .

There are many paths to reduce the LCOE for UPV systems to the target set for 2030, but they all rely on improvement in seven key parameters: module conversion efficiency, module cost, balance-of-system (BOS) cost, initial operating cost, operating cost escalation, initial annual energy yield, and degradation rate. 9 Table I lists .

The steady progression of scientific achievements are making wind and solar as cost-efficient to produce as fossil fuels, and increasingly competitive at storing energy as well.

When it comes to the cost of energy from new power plants, onshore wind and solar are now the cheapest sources—costing less than gas, geothermal, coal, or nuclear.

To satisfy increasing demand more solar modules get deployed, which leads to falling prices; at those lower prices the technology becomes cost-effective in new applications, which in turn means that demand increases.

6 FAQs about [Solar power generation is not cost-effective]

Do solar energy benefits outweigh the costs?

Benefits of solar photovoltaic energy generation outweigh the costs, according to new research from the MIT Energy Initiative. Over a seven-year period, decline in PV costs outpaced decline in value; by 2017, market, health, and climate benefits outweighed the cost of PV systems.

Are solar PV projects reducing the cost of electricity in 2022?

Between 2022 and 2023, utility-scale solar PV projects showed the most significant decrease (by 12%). For newly commissioned onshore wind projects, the global weighted average LCOE fell by 3% year-on-year; whilst for offshore wind, the cost of electricity of new projects decreased by 7% compared to 2022.

Are solar and wind more expensive?

But though it was once true, that assumption has actually been obliterated by a recent decline in solar and wind costs over the past decade. When it comes to the cost of energy from new power plants, onshore wind and solar are now the cheapest sources—costing less than gas, geothermal, coal, or nuclear.

Are solar and wind power cost-competitive?

For the last 13 to 15 years, renewable power generation costs from solar and wind power have been falling. Between 2010 and 2022, solar and wind power became cost-competitive with fossil fuels even without financial support.

Are wind & solar energy more cost-efficient than fossil fuels?

But that is changing. The steady progression of scientific achievements are making wind and solar as cost-efficient to produce as fossil fuels, and increasingly competitive at storing energy as well.

Why do electricity generators cost so much?

The price paid to every selected generator is set by the highest-cost operator on the system, so as more PV power comes on, more high-cost generators come off, and the price drops for everyone. As a result, in the middle of the day, when solar is generating the most, prices paid to electricity generators are at their lowest.
