Small-scale solar power wholesale market

What is the capacity of small-scale solar power?

Small-scale solar power systems, including rooftop panels installed on homes and those used in the commercial and industrial sectors, have a capacity of up to 39.5 GW in the United States as of 2022. These estimates were first published in 2014 when the capacity was 7.3 GW.

How much does solar cost?

Solar’s energy and capacity value varies from one wholesale market to another: It is lower in CAISO at $51/MWh, but high in many southeastern regions ($84-108/MWh), PJM ($85/MWh), Indiana ($81/MWh), or ISO-NE ($77/MWh.

How much is solar energy worth?

Solar’s energy and capacity value varies from one wholesale market to another: It is low in CAISO at $34/MWh, but high in ERCOT ($78/MWh), SPP ($71/MWh) and PSCO ($66/MWh). But value also varies within regions, driven by transmission congestion, solar resource quality or differing use of technology like trackers.

How much does it cost to build a solar power plant?

The median installed cost of projects that came online in 2022 fell to $1.3/WAC ($1.1 /WDC), down 13% from 2021 and 78% from 2010. Average capacity factors range from 17% in the least-sunny regions to 32% where it is sunniest.

Will the global solar market grow in 2022?

For each year up to 2025, we have considerably increased our forecasts, but 2022 will stand out. In our Medium Scenario, we see the global solar market increase by 25% to 203 GW in 2022, the first time that annual PV installations will cross the 200 GW level, which we had previously expected to be accomplished only in 2024.

What is regional solar value?

The regional solar value is the generation-weighted average value of all large-scale (1 MW+) solar generation in a given balancing authority. The energy value typically makes up the bulk of total market value (80% in 2021), but capacity value is significant in eastern markets in particular.
