Summary
California's Solar Rights Act (Civil Code 714) and Solar Shade Control Act protect homeowners' right to install solar panels. HOAs in San Marcos cannot effectively prohibit or unreasonably restrict solar installations.
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.

Full Breakdown
Under California Civil Code Section 714 (Solar Rights Act), HOAs in San Marcos cannot prohibit or effectively restrict the installation of solar energy systems on single-family homes. An HOA may impose reasonable restrictions that do not significantly increase cost (by more than $1,000 or 10%) or decrease system efficiency (by more than 10%). The Solar Shade Control Act (Public Resources Code 25980-25986) protects solar access by restricting neighbors from planting trees that shade existing solar panels. HOAs cannot require architectural committee approval that would delay installation beyond 45 days. San Marcos city permitting does not require HOA sign-off as a condition of building permit approval. Disputes between homeowners and HOAs over solar installations can be resolved through the Davis-Stirling Act mediation and arbitration provisions.
Violations & Fines
HOA restrictions that violate Civil Code 714 are void and unenforceable. Homeowners may recover legal fees from HOAs that impose unlawful restrictions.
