Solar power generation costs less than the grid

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 .

Furthermore, as the cost of solar decreases and efficiency increases, the technology approaches grid parity, which is when solar power costs less than, or equal to, the cost of electricity from conventional fossil fuel sources like coal, oil, and natural gas. The goal of grid parity is to make solar more affordable than fossil fuel power, even .

Many people ask when the cost of producing power from solar photovoltaic (PV) panels will be equal to or less than buying from the grid – a point called “grid parity” that could accelerate solar adoption.

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 benefits from renewables in 2022 will be unprecedented, given the fossil fuel price crisis: The lifetime cost per kWh of new solar and wind capacity added in Europe in 2021 will average at least four to six times less than the marginal generating costs of fossil fuels in 2022.

6 FAQs about [Solar power generation costs less than the grid]

How does solar energy affect grid parity?

Can photovoltaic electricity be compared to grid prices in China?

Although solar photovoltaic use grows rapidly in China, comparison with grid prices is difficult as photovoltaic electricity prices depend on local factors. Using prefecture-level data, Yan et al. find that 100% of user-side systems can achieve grid parity, while 22% can produce electricity cheaper than coal-based power plants.

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.

Can cities achieve low solar electricity prices without subsidies?

We reveal that all of these cities can achieve—without subsidies—solar PV electricity prices lower than grid-supplied prices, and around 22% of the cities’ solar generation electricity prices can compete with desulfurized coal benchmark electricity prices.

Why are solar power prices changing?

That adjustment is due to changes in market prices that accompany significant growth in PV generation — changes that will occur in other regions as they start to ramp up their solar generation. The researchers stress that conditions are constantly changing on power grids and electricity markets.

Will solar power supply more than half of US electricity by 2050?

With increased grid flexibility and more aggressive cost declines in solar and synergistic technologies like energy storage, solar power has the potential to supply a much greater share of U.S. electricity, including the potential to supply more than one-quarter to one-half of U.S. electricity by 2050.
