Title 24: What Are California’s Solar Mandates for 2020? | Simply Solar

Need help understanding the updated California Solar Mandates for 2020? We’ve got you covered. Let us break it down for you!

What is Title 24? 

According to the California Energy Commission, the Title 24 requirements are “designed to reduce wasteful and unnecessary energy consumption in newly constructed and existing buildings.” Essentially, Title 24 establishes Building Energy Efficiency Standards for the construction of new buildings as well as the addition to or alteration of existing buildings. Title 24 requirements are updated every 3 years, and adopt improvements that incorporate new energy efficient technologies and new construction methods. These standards save energy, increase home electricity supply, limit the need to construct new power plants, and help mitigate the climate crisis.

California’s Building Standard Codes

Part 6 of Title 24, which was updated in January 2020, outlines the California Building Standards Energy code. The updated California solar mandates of 2020 requires that all new residential homes meet Title 24 requirements. This makes California’s code the first in the nation to require solar for newly built homes!

The updated goal is designed to increase energy efficient homes in California, save consumers money, and improve the quality of our environment. As the destructive wildfires of the past years have taught us, it is of growing importance to understand and improve our energy usage. As the first state in the U.S. to have such a solar mandate, California has been consistently leading the charge on climate change and energy improvements.



California Solar Mandate 2020: Home Requirements

California’s 2020 Solar Mandate requires all new homes to install solar photovoltaic (PV) systems. These requirements are based on the floor area of the home and the climate zone. There may be exceptions to the mandate, like a property being too shaded or having too small a roof to install solar panels.

The solar panel systems must be sized to provide for the full annual energy usage of the home. In the hopes to increase home energy efficiency, it’s expected that sizes will generally range between 2.7 kilowatts and 5.7 kilowatts under the new Title 24 requirements. These average system sizes are because new homes will be more energy efficient overall.


Cost Savings with Title 24 Requirements

The California Clean Energy Commission reports that Part 6 of Title 24 may increase the upfront cost of a single-family home development by roughly $8,400. However, this up-front cost is balanced by long-term savings on monthly electric bills. It is projected that the solar system will pay for itself in 5-10 years!
