What a residential solar installation actually involves

A home solar system is four things bolted together: modules that convert sunlight to direct current, electronics that convert it to alternating current your house can use, a racking system that attaches all of it to your roof without letting water in, and the electrical work that ties it into your main panel and your utility’s grid. Getting the modules right is the easy part. The other three are where installations succeed or fail.

Step one: the site audit, and what we are actually looking at

We measure the roof planes — pitch, azimuth and usable area on each — and run a shade study across the whole year, not just the day we visit. A tree that clears your array in June can sit right across it in December when the sun is twenty-five degrees lower.

We also check three things that decide whether the quote you get is real:

• Roof age and condition. If the covering has under seven to ten years left, you should re-roof first. We will say so.
• Structural adequacy. Rafter dimension, spacing and span, plus any existing sag. Most Sacramento roofs are fine; some 1950s low-slope roofs need reinforcement.
• Main service panel. Busbar rating and available breaker space. A great many homes in Arden-Arcade, Rosemont and central Sacramento still have 100-amp service, and a panel upgrade is a real line item — one we would rather identify now than discover on installation day.

Step two: design and the production model

System size comes from your usage, not from your roof size. We read twelve months of billing data, identify your seasonal pattern and size to it — then check whether your roof can actually carry that array. If it cannot, we tell you what the shortfall means rather than quietly quoting less and letting you find out later.

The proposal shows the annual kilowatt-hour estimate and the assumptions behind it: tilt, azimuth, shade loss, soiling loss, inverter efficiency and the annual degradation rate. You can put those same inputs into NREL’s PVWatts and check our arithmetic. We would rather you did.

Step three: inverter architecture — the decision that matters most

String inverters, string inverters with optimisers, and microinverters all work. Which is right for you depends almost entirely on shade and roof complexity, and Sacramento’s oak canopy makes this a live question on a majority of older lots. A single shaded panel on a plain string system drags down every panel on that string; with module-level electronics it only loses its own output. Read the full comparison in microinverters and optimisers.

Step four: permits and plan check

Structural and electrical drawings go to your city or county building department. Sacramento County handles unincorporated Carmichael, Fair Oaks, Orangevale, Antelope and Arden-Arcade; Elk Grove, Folsom, Citrus Heights, Rancho Cordova and Roseville each run their own. Turnaround varies from a few days to several weeks. We submit, we respond to corrections, and you hear from us when there is something to report — not before.

Step five: installation

One to three days for a typical residential system. Racking goes on first, each attachment flashed into the roof covering properly; then modules, then conduit, then the electrical tie-in. Conduit routing is planned before anyone picks up a drill, because badly routed conduit across a front elevation is permanent and ugly.

Step six: inspection and permission to operate

The building department inspects. Then your utility processes the interconnection and issues permission to operate — and only at that point may the system legally run. This last stage is the one most outside anybody’s control, and anyone promising you a firm switch-on date before plan check is finished is guessing.

What makes a Sacramento installation different

Three things, repeatedly:

• The utility split. SMUD, PG&E, Roseville Electric and Lodi Electric all credit exported power differently, and that changes the ideal system size and whether storage pays. See the utility comparison.
• The oaks. Protected valley oaks mean removing the shade is usually not an option. Design around it instead.
• The heat. Sustained 100°F-plus summers mean high cooling load — good for the economics — but also panel temperature well above standard test conditions, which a credible production model accounts for.
