Optimizing Residential Solar Energy Systems for Efficiency, Reliability, and Cost

The California 2022 Building Energy Efficiency Standards are the first US building codes to mandate solar for new residential homes. With legislative efforts being made to enact similar standards in other regions, it should be no surprise that the solar market is projected to have incredible growth over the next decade.

The photovoltaic inverter market from 2021 to 2025 is expected to reach nearly 1 terawatt of capacity for a total market value of $54 billion.

According to Solar Industry Research Data, the percentage of residential and commercial solar systems paired with energy storage systems is on the rise, increasing from 11% in 2021 to an expected 29% by 2025.

The growth in the solar residential market is bolstered by increasing energy costs and solar system cost reduction of approximately 33% over a 5−year period. In the United States, the percentage of new energy capacity additions contributed by solar was 50% of the total in 2022 compared to 25% in 2018.

This white paper examines the main components of residential solar systems and suggests some power solutions from onsemi to make them more efficient, reliable, and cost-competitive.
