Tile Roofs Separate Good Installers From the Rest

Concrete tile is everywhere in the Inland Empire, and it is unforgiving. Tiles have to be lifted, flashed underneath and set back without cracking, and a rushed job shows up as a leak the first winter.

The homeowner also wanted backup power, not just savings. That meant a battery sized for the house and a backup switch that lets the whole home island when the grid drops.

Scope Delivered

Tile Roof Array

Fifteen all-black modules on IronRidge rail, split across two roof planes, with every attachment flashed beneath the tile.

Powerwall 3

Tesla Powerwall 3 serving as both the solar inverter and a 13.5 kWh battery, DC-coupled so solar charges it without extra conversion losses.

Whole-Home Backup

A Tesla Backup Switch at the meter, a new AC disconnect, and a rapid-shutdown breaker box, with the existing 200A panel kept in service.

How We Built It Right

Flashed under the tile

Every roof attachment is flashed beneath the tile layer, the method that keeps water out for the life of the roof. Tiles are reset, not mortared over.

All-black, flush and tidy

Black-frame, black-backsheet modules sit low and even on the rail so the array reads as part of the roof from the street. Conduit runs on the roof are kept short and straight.

Battery mounted clean on the wall

The Powerwall sits flat on the side-yard wall with the conduit run plumb, out of the way of foot traffic and easy to service.

What This Project Proves for Your Property

If you have a tile roof and have been told it is a problem for solar, it is not, with the right crew. This system went from install to SCE permission to operate in about two months.

Keen installs residential solar and batteries across Riverside County, including Temecula, Murrieta and Menifee. See our residential solar page.

Questions About Projects Like This

Can you put solar on a concrete tile roof? +
Yes. Tiles are lifted, each attachment is flashed underneath, and the tiles are reset. It takes more care and time than composition shingle, which is why tile is usually priced as an adder.
Does a Powerwall 3 back up the whole house? +
With a Backup Switch, the home can island during an outage. How long it runs depends on what you power and how much sun there is to recharge it. We size the system around the loads that matter to you.
