Las Vegas, NV Solar Energy: Panel Permits (2026)

LVMC 19.12.070 classifies a "Solar Panel" as a small-scale unit installed on an incidental or accessory basis to generate power or heat for the principal use on the same site, distinct from an "electric generating plant" regulated separately under LVMC Chapter 19.18. Because a solar installation is not treated as an accessory structure under the Title's dimensional standards, it is instead approved through the conditional use process and must meet a specific set of Conditional Use Regulations.

Where the panels are visible from a public right-of-way, they may project no more than 40 inches from the roof surface. On a sloped roof, the enclosure cladding and support structure, aside from the solar collection cells themselves, must match the color and appearance of the roof. A roof-mounted hot-water storage tank tied to the system cannot be visible from neighboring properties or public rights-of-way. If the property sits within a designated Historic District, the location of the proposed panels must first go through design review and approval under LVMC 19.10.150 before installation.

Solar installations do not trigger any additional on-site parking requirement beyond what the principal use already requires. Separately, LVMC 19.06.040(D)(1) confirms that a roof-mounted solar panel unit approved as a conditional use under Chapter 19.12 is excluded from the building's height calculation, so a rooftop array will not push a house or commercial building over its district's maximum height limit. The conditional use approval runs through the Department of Planning's review process rather than through the district's by-right development standards tables.
