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 system pricing table above to select one of our systems based on the calculator's findings.
You will also require a Solar PV Permit Plan Set for your project. Detailed information about this service can be found below.

See the "Included Components" dropdown under each panel tab for the full list specific to that system.
Do I need a permit to install a solar system?
Yes - most jurisdictions in the United States require a building permit for solar PV installations. A Solar PV Permit Plan Set makes the permitting process much easier by providing all required drawings and documentation. We offer permit plan set services for any state, including detailed rafter/mounting drawings, electrical wiring diagrams, and PE stamps when needed.
What size solar system do I need for my ADU or small building?
System size depends on your energy consumption, available roof space, and local sun exposure. For California new construction, the Title 24 PV System Size Calculator (available through your architect or Title 24 consultant) will determine the minimum required system size. For existing buildings, review your electric bill to find your average monthly kWh usage - our systems range from 2 kW to 9 kW and cover most ADU, small home, and light commercial applications. Contact us and our experienced staff can help you size the right system.
Can I add battery storage to my system later?
Yes - all of our systems support optional battery storage add-ons. The available storage options depend on which inverter you select. You can add storage at the time of purchase by using the "Add Storage" option in the pricing table, or you can retrofit storage later as long as your inverter platform supports it. We offer storage solutions from Enphase, Sigenergy, EcoFlow, and more.
Do you offer contractor or installer pricing?
Yes - we offer Special Discount Pricing for authorized contractors through our contractor network. This is ideal for contractors competing for bids or managing multiple installations. Apply here to join our network and receive access to contractor-level pricing on all systems.
