Domestic solar power generation cost performance

The last decade has shown a sharp, though now steadying, decline in costs, driven largely by photovoltaic (PV) module efficiencies (now 19.5%, up from 19.2% in 2019) and hardware and inverter costs.

Calculating LCOE for solar power requires four main inputs: system capital cost, system operating cost, solar resource, and a financial model. PVSCM provides the first two inputs for each benchmark system.

Domestic solar power generation has increased over the past decade, enabled by technological advances, government support, state-level policies mandating use of electricity from renewable sources, and improved cost-competitiveness relative.

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 .

All technologies demonstrate some degree of variability in cost, based on project size, location, and access to key infrastructure (such as grid interconnections, fuel supply, and transportation). For wind and solar PV, in particular, the cost favorability of the lowest-cost regions compound the underlying variability in regional cost and .

6 FAQs about [Domestic solar power generation cost performance]

How much does a solar PV system cost?

“A significant portion of the cost declines over the past decade can be attributed to an 85% cost decline in module price. A decade ago, the module alone cost around $2.50 per watt, and now an entire utility-scale PV system costs around $1 per watt,” said NREL Senior Financial Analyst David Feldman.

How much does solar power cost?

Solar photovoltaics (PV) shows the sharpest cost decline over 2010-2019 at 82%, followed by concentrating solar power (CSP) at 47%, onshore wind at 40% and offshore wind at 29%. Electricity costs from utility-scale solar PV fell 13% year-on-year, reaching nearly seven cents (USD 0.068) per kilowatt-hour (kWh) in 2019.

What is solar energy cost analysis?

Solar energy cost analysis examines hardware and non-hardware (soft) manufacturing and installation costs, including the effect of policy and market impacts. Solar energy data analysis examines a wide range of issues such as solar adoption trends and the performance and reliability of solar energy generation facilities.

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.

How to expand domestic solar PV system components in a competitive global market?

Strategies for expanding domestic output of solar PV system components in a highly competitive global market include improving product performance, lowering costs of production through automation and manufacturing advancements, and developing solar panel recycling pathways.

Are soft costs affecting solar installation costs?

As in previous years, soft costs remain a large and persistent portion of installation costs, for both solar and storage systems, and especially for commercial and residential systems. “A significant portion of the cost declines over the past decade can be attributed to an 85% cost decline in module price.
