Hiring Solar Contractors

Solar installation in California can be performed by a C-46 Solar Contractor, a C-10 Electrical Contractor, or a general building contractor working with licensed electrical subcontractors, each a valid licensing path recognized by the Contractors State License Board. One practical difference worth knowing: battery storage installed alongside solar generally requires C-10 electrical licensing specifically, since C-46-only contractors lost that authorization in 2021. The trade covers everything from a full rooftop system installation to ongoing panel cleaning and system maintenance, and not every solar vendor handles both ends of that range. Wrkbid connects homeowners with solar contractors already bidding on installation and maintenance work nearby, so proposals can be compared on licensing, scope, and price before committing to a system.

How to Get Bids from Solar Contractors on Wrkbid

Solar projects involve more moving parts than a typical home repair, so the more detail your post includes, the more accurate the bids that come back. A strong post specifies:

  • Project type: new installation, a system expansion, battery storage addition, or maintenance and repair on an existing system
  • Roof or property details: roof type and age if known, approximate square footage or your average monthly electric bill, and any shading concerns such as trees or nearby structures
  • Photos: photos of your roof, electrical panel, and property help a contractor scope the project before a site visit
  • Financing preference: whether you're planning to pay cash, finance with a loan, or are considering a lease or power purchase agreement, since this affects which proposals make sense to compare
  • Timeline: any target date, and whether you're trying to complete interconnection before a specific utility program deadline
  • Battery storage interest: flag upfront if you want battery storage included, since this affects which contractors and licensing are relevant

Posting this level of detail once, rather than repeating it on separate calls to each contractor, is the main advantage of collecting bids through a single request rather than contacting solar contractors one at a time.

What to Look for in a Bid from Solar Contractors

Solar system pricing varies enormously by system size, equipment, and financing, so a single price range is less useful here than for a smaller home repair. A few things are worth comparing across every bid:

  • Licensing: verify appropriate licensing for the scope of your project, and confirm C-10 electrical licensing specifically if battery storage is part of the job
  • Who handles interconnection: the utility interconnection application and net metering enrollment is typically handled by the contractor on your behalf. Confirm this is included, not a separate task left to you
  • Permitting handled: confirm who pulls the required permits and whether that's included in the bid
  • Equipment specified: panel brand and model, inverter type, and system size in kW should all be named specifically, not left as "premium panels"
  • Warranty terms, all three layers: manufacturer product warranty (defects), performance warranty (power output over time), and the installer's separate workmanship warranty (the installation itself). Ask for all three in writing, since a strong product warranty doesn't cover a poorly sealed roof penetration
  • Financing terms in writing: for a loan, lease, or power purchase agreement, get the full payment schedule, any dealer fees baked into a loan, and annual price escalators in a lease or PPA, in writing before signing
  • Post-install maintenance: ask whether cleaning and inspection are included, offered as a separate plan, or left entirely to you

A lower bid isn't automatically the better deal on a purchase this large. Equipment quality, financing terms, and the strength of the workmanship warranty generally matter more to your long-term cost than the sticker price alone.

Frequently Asked Questions

Solar installation can be performed by a C-46 Solar Contractor, a C-10 Electrical Contractor, or a general contractor working with licensed electrical subs, all recognized paths under California's Contractors State License Board. If battery storage is part of your project, C-10 electrical licensing specifically is required, since C-46-only contractors are no longer authorized to install battery systems. Verify appropriate licensing for your specific project scope before signing.

Your solar contractor typically handles the interconnection application and net metering enrollment with your utility on your behalf, as part of a standard installation. Confirm this is included in your bid rather than left as a separate task, since interconnection review can take several weeks and is usually the longest single step in the process.

For an installation, include your roof type and age, approximate electric bill or usage, photos of your roof and electrical panel, whether you want battery storage, and your financing preference. For a maintenance request, include your system's approximate age, panel count, and whether you're requesting a one-time inspection or ongoing service.

Beyond the equipment and price, clarify the full financing terms in writing, including any dealer fees for a loan or annual escalators for a lease, what prep work is required before installation, what the post-installation and interconnection process looks like, and the specific terms of all three warranty layers: product, performance, and workmanship.

Three separate warranties typically apply. A manufacturer product warranty, commonly 25 years on premium panels, covers manufacturing defects. A performance warranty, also commonly 25 to 30 years, guarantees the system won't degrade below a stated output level. A workmanship warranty from your installer, commonly 5 to 10 years, covers the quality of the installation itself: mounting, wiring, and roof penetrations. Ask for all three in writing, since a strong product warranty doesn't cover a labor issue.

The physical installation itself is often just 1 to 3 days for a standard residential system. The full process from signed contract to system activation commonly takes 6 to 14 weeks, since permitting, utility interconnection review, and final inspection each add their own timeline beyond the installation itself.

Yes, though it's relatively light. Panels commonly benefit from cleaning every 3 to 6 months depending on dust, pollen, and local conditions, along with an annual professional inspection. Most systems also include monitoring software that flags a drop in output, often the first sign something needs attention between scheduled inspections.

Each has different tradeoffs. Buying with cash or a loan means you own the system and generally see the highest long-term savings, plus eligibility for the federal tax credit. A lease or power purchase agreement lowers the upfront cost and shifts maintenance responsibility to the provider, but commonly includes annual price increases and can complicate a home sale later. Compare the full terms, not just the monthly payment, and get financing details in writing before signing, since it's worth doing your own research on which structure fits your situation rather than assuming one option is universally better.
