We can help with the New California Construction Title 24 Solar Requirements

To determine the minimum size required for your PV solar system, you can use the California PV System Size Calculator. Typically, this calculator is available through your architect or Title 24 Consultant. Refer to the chart below to select one of our systems based on the calculator's findings.

Before deciding to add a solar system, a Solar Assessment Study is essential. This study helps ascertain the feasibility of a solar system for your specific location, considering factors like excessive shading that might negate the need for one.

Additionally, you will require a Solar PV Permit Plan Set for your project. Detailed information about these services, including their respective fees, can be found below.

Frequently Asked Questions

Understanding the California Solar Mandate: Requirements, Exemptions, and Implications for New Constructions

What are the California Solar Mandate requirements for new homes and ADUs?

California's 2020 Solar Mandate stipulates that all new residential homes, including Accessory Dwelling Units (ADUs), must be equipped with solar photovoltaic systems. These systems should be adequately sized based on the specific home's floor area and the local climate zone, with the goal being to offset the full annual energy consumption of the home. The typical size for residential solar systems under this mandate is expected to range between 2.7 and 5 kilowatts, dependent on the energy efficiency of the building and local climate conditions.

Is solar panel installation mandatory for all new constructions in California?

Yes, solar panel installation is generally required for all new residential constructions. However, exemptions are allowed under certain conditions such as significant shading due to large trees or other buildings, or in cases where the roof area is insufficient for a solar installation. In some cases, homeowners can opt for community solar programs as an alternative to individual rooftop systems.

How does the 2022 Energy Code update affect solar system installations?

The recent 2022 Energy Code update has introduced new requirements for single-family homes to be ready for electrification, which includes pre-wiring for future electric appliances and heating systems, and vehicle charging infrastructure. In addition, there is now guidance on installing battery storage systems. This indicates a clear goal to further incorporate solar-powered energy storage solutions into residential properties, aiming to enhance the overall energy efficiency and sustainability of new buildings.

Are there exemptions to the solar mandates for homes with excessive shading or limited roof space?

Homes with conditions that significantly impede solar production, such as excessive shading from nearby objects or limited roof space, may qualify for an exemption from the solar mandate. Alternatives such as solar carports, ground-mounted solar systems, or participating in community solar programs might provide feasible options for those who face challenges with traditional rooftop installations.

What are the cost and long-term savings associated with Title 24 solar requirements?

While the initial cost of implementing Title 24 compliant solar installations on new homes is estimated to be increased by approximately $8,400, there are significant long-term savings to consider. By reducing monthly electric bills, the solar power system installation costs are expected to be recouped within a period of five to ten years, ultimately resulting in substantial savings over the lifespan of the solar system.

What is the significance of battery storage in the context of the solar mandates, and what are the implications for future code updates?

The focus on battery storage in the latest energy code updates is a strong indicator of California's vision for future energy systems. Battery storage systems not only provide a way to store excess solar energy generated during peak sunlight hours, but they also enhance the resilience of the power supply against outages and reduce the strain on the grid during high-demand periods. The implication of including battery storage in the regulations points towards a trend of future code updates likely to promote even greater energy independence and sustainability for residential energy systems.
