Summary
California Civil Code Section 714 (Solar Rights Act) prohibits San Ramon HOAs from banning solar panels. HOAs and CC&Rs can impose only 'reasonable restrictions': those that do not significantly increase system cost (over $1,000 for PV) or decrease efficiency by more than 10%. HOA approval must be granted within 45 days or it is deemed approved. Civil Code 4600 and 4745 reinforce homeowner solar rights. San Ramon's many HOA communities (Gale Ranch, Windemere, Canyon Lakes) must comply.
714. (a) Any covenant, restriction, or condition contained in any deed, contract, security instrument, or other instrument affecting the transfer or sale of, or any interest in, real property, and any provision of a governing document, as defined in Section 4150 or 6552, that effectively prohibits or restricts the installation or use of a solar energy system is void and unenforceable.
(b) This section does not apply to provisions that impose reasonable restrictions on solar energy systems. However, it is the policy of the state to promote and encourage the use of solar energy systems and to remove obstacles thereto. Accordingly, reasonable restrictions on a solar energy system are those restrictions that do not significantly increase the cost of the system or significantly decrease its efficiency or specified performance, or that allow for an alternative system of comparable cost, efficiency, and energy conservation benefits.
(c) (1) A solar energy system shall meet applicable health and safety standards and requirements imposed by state and local permitting authorities, consistent with Section 65850.5 of the Government Code.
(2) Solar energy systems used for heating water in single family residences and solar collectors used for heating water in commercial or swimming pool applications shall be certified by an accredited listing agency as defined in the Plumbing and Mechanical Codes.
(3) A solar energy system for producing electricity shall also meet all applicable safety and performance standards established by the California Electrical Code, the Institute of Electrical and Electronics Engineers, and accredited testing laboratories such as Underwriters Laboratories and, where applicable, rules of the Public Utilities Commission regarding safety and reliability.
(d) For the purposes of this section:
(1) (A) For solar domestic water heating systems or solar swimming pool heating systems that comply with state and federal law, “significantly” means an amount exceeding 10 percent of the cost of the system, but in no case more than one thousand dollars ($1,000), or decreasing the efficiency of the solar energy system by an amount exceeding 10 percent, as originally specified and proposed.
(B) For photovoltaic systems that comply with state and federal law, “significantly” means an amount not to exceed one thousand dollars ($1,000) over the system cost as originally specified and proposed, or a decrease in system efficiency of an amount exceeding 10 percent as originally specified and proposed.
(2) “Solar energy system” has the same meaning as defined in paragraphs (1) and (2) of subdivision (a) of Section 801.5.

Full Breakdown
California Civil Code Section 714, originally enacted in 1978 and strengthened multiple times, is the governing law on HOA solar rights. An HOA, CC&R, or architectural committee may not ban solar energy systems on residential property. Restrictions are only valid if they are 'reasonable', defined as not significantly increasing the cost of the system (over $1,000 for solar PV per AB 2188 amendments) or significantly decreasing its efficiency (more than 10%). AB 634 (2017) further restricted HOA authority over common area solar in multifamily. AB 2188 (2014) and Civil Code 4600/4745 require HOAs to act on solar applications within 45 days, failure to respond is automatic approval.
HOAs may still reasonably regulate aesthetics (conduit routing, color, panel alignment) as long as those regulations do not cross the $1,000 / 10% efficiency thresholds. In San Ramon, many planned communities, Gale Ranch, Windemere, Canyon Lakes Country Club, Crow Canyon Country Club, Twin Creeks, have HOAs with architectural review committees that handle solar applications. Homeowners denied approval or subjected to unreasonable restrictions have a private right of action under Civil Code 714; the prevailing party may recover attorneys' fees. Civil Code 4746 (2021) extended solar rights to common area roofs of condos/townhomes.
Battery storage systems are also protected. 1. Disputes often involve aesthetic concerns (panels visible from street), HOAs must accept such systems if repositioning would reduce efficiency beyond the statutory threshold.
