The story
Tony bought the house on Tondolea Lane in early 2024. It had a clay tile roof — the kind that costs twice as much to replace and breaks if you drill at the wrong angle. The previous installers he'd spoken to said the same thing: fragile tile, too much liability, not worth the risk.
Our crew assessed the roof. The tile was sound. The rafters were rated for the load. QuickMOUNT Tile Hooks and IronRidge XR10 rails — hardware made specifically for this kind of roof. Thirty points of attachment, each one set through a clay tile. Thirty times. Not one cracked. We replaced the main service panel with a new 200-amp unit as part of the same job.
La Cañada Flintridge summers are long and hot. The San Gabriel foothills push afternoon temperatures into triple digits by July. The pool in the backyard runs a pump twelve months a year. The array was sized for that load, facing southwest at 16°. A central string inverter on the side of the house. Module-level optimizers, one per panel, each reporting output individually.
The City of La Cañada Flintridge Building & Safety issued the permit. SCE interconnected the system. It went live.
The same hooks have gone onto clay, concrete, and slate roofs across the foothills since.
Tony never called.
What we did
- Pre-install structural assessment of the pitched clay tile roof.
- 30 stainless steel attachment points using QuickMOUNT Tile Hooks — no tile damage.
- IronRidge XR10 rail system mounted above the tile surface on conduit blocks.
- 30 high-efficiency solar panels installed in two strings facing southwest at 16°.
- Module-level power optimizers wired to every panel for per-panel monitoring.
- Central string inverter mounted on exterior wall, within code-required distance of the panel.
- 200A main service panel upgrade with PV breaker installation.
- Full permit package submitted to City of La Cañada Flintridge Building & Safety; AHJ inspection passed.
- SCE NEM 2.0 interconnection coordinated and activated.
- All work completed by Cali Energy's own licensed crew — no subcontractors (CSLB #1032379).

Frequently asked questions
Does solar work on clay tile roofs in La Cañada Flintridge?
Yes. It just needs the right hardware. QuickMOUNT Tile Hooks slide under each tile and lock into the rafter below — no drilling through the tile itself. Watertight and structurally sound.
What does a power optimizer do that a string inverter doesn't?
A standard string inverter averages output across all panels — one shaded panel drags the whole string down. Optimizers give every panel its own tracker. If shade hits two panels, the other 28 run at full strength. You also see what each panel produces, day by day.
How do I know the clay tile roof won't leak after solar installation?
Every QuickMOUNT Tile Hook has a neoprene seal compressed against the tile. IronRidge rails sit on conduit blocks above the surface — not through it. The roof passed City of La Cañada Flintridge inspection before the permit closed. No leaks, no service calls since.
