Solar in Piedmont.

Last updated: September 16, 2026

The economics are the easy part

Piedmont homes tend to be large, frequently with a pool, air conditioning, two EVs, or all three. Under NEM 3, a big evening load is exactly what makes solar and storage work — the value is in what you avoid buying at PG&E's retail rate, and there's a lot of it here.

The result is that I spend less time on Piedmont visits establishing whether a project makes sense and more on the two questions that actually decide it: what the roof can carry, and what the city and your neighbors will be looking at.

Design review, realistically

Piedmont cares about how things look, and homeowners here ask me about design review more than anywhere else I work. Two things are true at once:

• California's Solar Rights Act meaningfully limits what a city can demand of a residential solar installation. A jurisdiction can't simply refuse solar on aesthetic grounds, and requirements that significantly raise cost or cut production face a real legal standard.
• In practice, a project designed with visibility in mind moves through a design-conscious city far more smoothly than one that isn't.

So I design for it rather than fight about it: all-black modules, panels hidden on rear and side planes where production allows, conduit run inside rather than across a facade, and flashing detailed properly on visible elevations. Most of the time you can get a well-producing array that a passerby doesn't notice, and that's a better outcome than winning an argument.

Requirements change and vary by property. Confirm anything specific with the City of Piedmont, or let me do it before you commit to a layout.

Tile, slate, and steep pitches

A large share of Piedmont roofs are the expensive kind to work on:

• Clay or concrete tile, which needs tile-specific mounts and hooks, careful removal and reset, and a crew that has done it before. Tile breaks. A good installer budgets for replacements and sources matching stock first.
• Slate, which is genuinely specialist work — and occasionally the honest answer is a ground mount or no array on that elevation.
• Steep pitch, which means fall protection, slower work, and more labor hours.
• Mature trees. Piedmont's canopy is part of why people live here. It also shades roofs, which pushes toward module-level electronics and a careful production estimate rather than an optimistic one.

All of this costs more than composition shingle on a simple pitch. A quote that treats a Piedmont tile roof like an Oakland flatland bungalow is a quote that will be revised later. The drivers are in what solar actually costs.

What I'd tell a Piedmont homeowner

Get the roof assessed honestly before anything else. On a tile or slate roof nearing the end of its life, installing solar first is an expensive mistake — removal and reinstallation later is a serious cost on this kind of roof, more than on most.

And be skeptical of anyone who quotes a Piedmont house quickly. The difference between a good install and a bad one here is almost entirely in the details of how the array meets the roof.
