California Attorney Fee Petition Mechanics — Bus. & Prof. Code § 7028 (D-46 Solar Thermal Systems / C-61 Limited Specialty — California Contractors State License Board)

California CSLB Solar Thermal Systems Contractor D-46 / C-61 Attorney Fee Petition Mechanics: Tyler Odyssey Civil Complaint Date as Primary Welch Anchor, CSLB License Check (D-46 / C-61) as Secondary Anchor (THE ONLY D-46 Solar Thermal Systems Page in This Series — DISTINCT FROM C-46 Solar [PV Electrical] and D-2/C-61 [Heating A/C and Solar — HVAC-Integrated] — ONLY Page With SRCC OG-100 Solar Collector Certification Advisory [THE ONLY PAGE in the Fee-Petition-Mechanics Series With an SRCC OG-100 Advisory — PURE KETCHUM] and SRCC OG-300 Solar Water Heating System Certification Advisory [PURE KETCHUM]; CEC Title 24 Part 6 JA8 Solar Water Heating Compliance as Second Institutional Anchor; OG-100 Non-Certified Collector Glazing Delamination Roof Penetration $45K / Glycol Stagnation PRV Discharge Scalding Injury $85K / Open-Loop No Freeze Protection Big Bear Pipe Burst $28K Three-Track Harm; Bus. & Prof. Code § 7031(b) Disgorgement), CLRA § 1780 Mandatory Attorney Fees

California Business and Professions Code § 7028 applies to every person who engages in the business of a contractor in California without holding a valid CSLB license. For installation, repair, and retrofit of solar thermal systems — flat-plate collectors, evacuated tube collectors, glycol closed-loop heat transfer systems, drainback systems, open-loop direct systems, differential temperature controllers, storage tanks, expansion vessels, and pressure relief valves for domestic hot water (DHW) and pool/spa heating — the relevant CSLB classification is D-46 (Solar Thermal Systems), a limited specialty classification issued under the C-61 Limited Specialty Contractor umbrella. D-46 is distinct from C-46 (Solar), the full specialty covering photovoltaic electrical solar power systems including panels, racking, inverters, DC/AC wiring, battery storage, and NEC Article 690 grid interconnection — D-46 covers solar thermal heat collection systems that do not generate electricity; and distinct from D-2/C-61 (Heating, Air-Conditioning and Solar Systems), which covers HVAC-integrated solar supplemental heating as part of a combined forced-air or hydronic system — D-46 covers standalone solar thermal DHW and pool heating systems. D-46 solar thermal work intersects SRCC OG-100 (Solar Collector Certification, published by the Solar Rating and Certification Corporation — private independent certification body under ANSI accreditation) for collector thermal performance, durability, and safety; and SRCC OG-300 (Solar Water Heating System Certification, Solar Rating and Certification Corporation) for complete system performance rating, glycol loop configuration, expansion vessel sizing, PRV selection, and freeze protection requirements. THREE UNIQUE DISTINCTIONS: (1) THE ONLY D-46/C-61 Solar Thermal Systems page in the fee-petition-mechanics series — DISTINCT FROM C-46 Solar [C-46 covers photovoltaic electrical solar power systems — PV panels, NEC Article 690 DC/AC wiring, inverters, battery storage; D-46 covers solar thermal flat-plate and evacuated tube collector systems that capture solar radiation as heat, not electricity] and DISTINCT FROM D-2/C-61 Heating A/C and Solar [D-2 covers HVAC-integrated solar supplemental heating as part of a combined forced-air or hydronic system; D-46 covers standalone solar thermal DHW and pool heating separate from any HVAC system] and DISTINCT FROM D-15/C-61 Hydronic Radiant Heating [D-15 covers closed-loop hydronic heating using boiler or heat pump; D-46 covers solar thermal collector-to-storage systems using solar radiation as the primary heat source]; (2) THE ONLY PAGE IN THE FEE-PETITION-MECHANICS SERIES with SRCC OG-100 SOLAR COLLECTOR CERTIFICATION ADVISORY + SRCC OG-300 SOLAR WATER HEATING SYSTEM CERTIFICATION ADVISORY — two distinct private SRCC certification standards on one page; (3) THE ONLY page with SRCC OG-100 NON-CERTIFIED COLLECTOR GLAZING DELAMINATION ROOF PENETRATION LEAK PLUS LADWP REBATE DISQUALIFICATION / GLYCOL STAGNATION 400°F EXPANSION VESSEL UNDERSIZED PRV DISCHARGE SCALDING INJURY / OPEN-LOOP DIRECT SYSTEM NO DRAINBACK NO FREEZE PROTECTION BIG BEAR RESORT PIPE FREEZE BURST $28K three-track harm.

TL;DR

Bus. & Prof. Code § 7028 requires CSLB D-46 / C-61 licensure for residential solar thermal systems work; unlicensed D-46 work activates the SRCC OG-100 advisory (THE ONLY page with SRCC OG-100 advisory — private SRCC certification standard — PURE KETCHUM), the SRCC OG-300 advisory (PURE KETCHUM), and the CEC Title 24 Part 6 JA8 solar water heating compliance permit as second institutional anchor; and the OG-100 non-certified collector glazing delamination / glycol stagnation PRV discharge scalding injury / open-loop freeze pipe burst CLRA three-track harm. Primary Welch anchor: Tyler Odyssey civil complaint date. Secondary anchor: CSLB License Check (D-46 / C-61). Bus. & Prof. Code § 7031(b) disgorgement. PURE KETCHUM. 13.25 hrs = $3,975–$6,625/yr.

Statutory Framework: Bus. & Prof. Code § 7028, D-46 / C-61 Solar Thermal Systems, SRCC OG-100 Advisory, SRCC OG-300 Advisory, CEC Title 24 JA8 Advisory, § 7031(b) Disgorgement, and CLRA § 1780 Mandatory Attorney Fees

California Business and Professions Code § 7028 prohibits unlicensed contracting. The CSLB D-46 (Solar Thermal Systems) limited specialty designation under C-61 authorizes: installation of flat-plate solar collector panels and evacuated tube collector arrays including roof mounting, flashing, and penetration weatherproofing; installation of closed-loop glycol heat transfer systems including heat exchangers, expansion vessels, fill/drain valves, and air eliminators; installation of open-loop direct systems and drainback systems; installation of differential temperature controllers (DTC) and associated sensors; installation of solar storage tanks (80–120 gallon single-element tanks) connected to conventional backup water heaters; installation of pressure relief valves (PRV) sized per ASME ratings on the collector loop and storage vessel; and service, repair, and retrofit of existing solar thermal DHW systems. D-46 does not cover: installation of photovoltaic solar electrical power systems (requires C-46 Solar); HVAC ductwork or refrigerant piping as part of solar-assisted heat pumps (requires C-20 or D-2); pool electrical wiring or pump wiring (requires C-10); or new plumbing connections at the water heater or storage tank inside the building envelope (requires C-36 Plumbing).

SRCC OG-100 (Solar Collector Certification, Solar Rating and Certification Corporation) is a private certification program operated by the Solar Rating and Certification Corporation (SRCC) under ANSI accreditation — it creates no private civil right of action and no mandatory attorney fee-shifting mechanism for persons harmed by unlicensed California D-46/C-61 solar thermal contractors. SRCC OG-100 certifies individual solar collectors (flat-plate and evacuated tube) for: thermal performance (Btu/day output at three insolation levels); collector efficiency curve (intercept and slope); durability testing including thermal shock, freeze resistance, hail impact, and pressure testing at 1.5× maximum operating pressure; and safety including materials compatibility, glazing retention, and housing integrity. Collectors must bear the OG-100 certification mark and be listed on the SRCC OG-100 product directory at solar-rating.org. California utilities including LADWP, PG&E, and SCE require SRCC OG-100 certification as a condition of solar water heater rebate eligibility (LADWP Solar Water Heater Rebate Program, SoCalGas TECH Clean California Rebate). PURE KETCHUM: SRCC OG-100 is a private Solar Rating and Certification Corporation certification standard — it creates no private civil right of action and no mandatory attorney fee-shifting mechanism.

SRCC OG-300 (Solar Water Heating System Certification, Solar Rating and Certification Corporation) is a private system-level certification standard — it creates no private civil right of action and no mandatory attorney fee-shifting mechanism. SRCC OG-300 rates complete solar water heating system packages for annual energy contribution, solar fraction (percentage of annual DHW load offset), freeze protection method (drainback, glycol, recirculation), expansion vessel sizing at stagnation temperature, and pressure relief valve configuration. OG-300-rated systems must include a properly sized expansion vessel pre-charged to system fill pressure, a PRV rated at or below the ASME MAWP of the storage tank (typically 150 psi), and freeze protection adequate for the installation climate zone. SRCC OG-300 is a private Solar Rating and Certification Corporation standard — PURE KETCHUM.

Primary Welch Anchor: Tyler Odyssey Civil Complaint Filing Date

The Tyler Odyssey civil complaint filing date is the primary Welch temporal anchor for D-46 solar thermal matters. The attorney files after confirming CSLB C-61/D-46 license status, searching the SRCC OG-100 product directory for the specific collector model installed, reviewing the CEC Title 24 JA8 compliance documentation filed with the building permit, retaining a NABCEP-certified solar thermal installer or licensed mechanical engineer to document OG-100/OG-300 non-compliance, documenting the rebate disqualification (Track 1), coordinating with treating physicians for scalding injury documentation (Track 2), and retaining a roofing and water damage contractor for freeze burst documentation (Track 3), and serving the CLRA § 1782 demand. The CSLB D-46/C-61 License Check date is the secondary Welch anchor. Ketchum v. Moses 24 Cal.4th 1122 (2001); PLCM Group Inc. v. Drexler 22 Cal.4th 1084 (2000).

Secondary Anchor: CSLB License Check (D-46 / C-61 Solar Thermal Systems) — THE ONLY D-46 Specialty Anchor in the Fee-Petition-Mechanics Series

The CSLB License Check must confirm the C-61/D-46 Solar Thermal Systems limited specialty designation — distinct from C-46 (Solar, which covers photovoltaic electrical systems), D-2 (Heating A/C and Solar, which covers HVAC-integrated solar supplemental heating), and C-36 (Plumbing, which covers the potable water connections inside the building envelope). Three scenarios generate § 7028 liability: (a) no CSLB license at all; (b) expired, suspended, or revoked C-61/D-46 license; (c) an HVAC contractor, plumber, or handyman who installs solar thermal DHW panels and glycol loop as a standalone service without holding the D-46 limited specialty. This page is THE ONLY D-46 Solar Thermal Systems specialty anchor in the fee-petition-mechanics series.

Billing Gap 1 — CSLB D-46/C-61 License Check, Tyler Odyssey Cross-Reference, SRCC OG-100 Directory Search, SRCC OG-300 System Review, CEC JA8 Permit Records, and § 1782 Demand (5.25 hrs/yr = $1,575–$2,625)

The first billing gap covers pre-complaint advisory for D-46 solar thermal matters.

  • Searching CSLB License Check for C-61/D-46 designation and establishing the secondary Welch anchor: confirming D-46 limited specialty presence or absence; evaluating C-46, D-2, and C-36 distinctions; confirming license status, bond, and workers compensation insurance; Tyler Odyssey cross-reference for prior judgments or pending matters against the same contractor.
  • SRCC OG-100 collector certification directory search: searching solar-rating.org OG-100 product directory for the specific collector manufacturer, model number, and serial range; confirming OG-100 certification was current and valid at the time of installation; documenting glazing specification (tempered low-iron solar glass vs. annealed glass) from OG-100 test report if available.
  • SRCC OG-300 system certification review: confirming whether the complete system package (collector + storage + controls) holds OG-300 certification; reviewing OG-300 freeze protection method requirement for the installation climate zone; reviewing expansion vessel sizing requirement at stagnation temperature; reviewing PRV specification at or below storage tank ASME MAWP.
  • CEC Title 24 Part 6 JA8 solar water heating compliance permit records — second institutional anchor: obtaining building permit file including CF1R-DHW energy compliance form; reviewing building inspector final inspection sign-off date and notes; confirming whether inspector verified OG-100 collector certification at final inspection.
  • Serving CLRA § 1782 demand incorporating SRCC OG-100 and OG-300 analysis: demand specifies D-46 unlicensed contracting, identifies three harm tracks, demands disgorgement under § 7031(b), and specifies CLRA § 1780 mandatory attorney fees.
Gap 1 Annual Value (D-46 CSLB search, Tyler Odyssey cross-reference, SRCC OG-100 directory search, OG-300 system review, CEC JA8 permit records)
$1,575–$2,625/yr
5 clients × 2.1 calls × 60 min × 50% untracked = 5.25 hrs/yr at $300–$500/hr median solo rate

Billing Gap 2 — Active Litigation: NABCEP Engineer (Track 1), Burn Injury Medical Expert (Track 2), Roofing Contractor Bid (Track 3), and Three-Track Damage Quantification (4.00 hrs/yr = $1,200–$2,000)

The second billing gap covers expert coordination across the three D-46 harm tracks.

  • Track 1 — NABCEP solar thermal engineer and water damage contractor for OG-100 non-certified collector glazing delamination and roof penetration: retaining a NABCEP Board-Certified Solar Thermal Installer (NABCEP BCSTI) to inspect the collectors, document glazing material (annealed vs. tempered solar glass), confirm OG-100 non-certification, and provide causation opinion linking non-certified glazing to thermal delamination and moisture intrusion; retaining a licensed contractor to bid $45,000 attic mold remediation and roof repair; documenting LADWP rebate disqualification letter as $2,200 economic damage.
  • Track 2 — burn injury medical expert and SRCC OG-300 expansion vessel engineer for PRV discharge scalding: coordinating with the injured homeowner's treating emergency medicine physician to document second-degree burn causation from hot glycol PRV discharge; retaining a licensed mechanical engineer to document the 0.5-gallon expansion vessel undersizing against SRCC OG-300 requirements for the 3.2-gallon glycol loop; quantifying $85,000 medical costs including emergency care, burn center treatment, and rehabilitation.
  • Track 3 — roofing contractor and NABCEP engineer for open-loop freeze pipe burst: retaining a NABCEP BCSTI to document the absence of any freeze protection — no drainback controller, no glycol, no recirculation thermostat — at a Big Bear Lake installation in Climate Zone 16; retaining a licensed roofing and general contractor to bid $28,000 collector removal, roof deck repair, flashing replacement, and interior water damage remediation.
  • Settlement valuation incorporating all three harm tracks and CLRA § 1780 mandatory attorney fees: D-46 three-track settlement demand integrates OG-100 mold remediation and rebate loss (Track 1), scalding medical costs (Track 2), and freeze burst and roof repair (Track 3) with CLRA mandatory attorney fees under the Ketchum multiplier.
Gap 2 Annual Value (NABCEP engineer, burn injury medical expert, roofing contractor bid, three-track damage quantification)
$1,200–$2,000/yr
4 clients × 2 calls × 60 min × 50% untracked = 4.00 hrs/yr at $300–$500/hr median solo rate

Billing Gap 3 — CLRA § 1780 Fee Petition, Pure Ketchum Multiplier, Lodestar Documentation, and Missouri v. Jenkins Fees-on-Fees (4.00 hrs/yr = $1,200–$2,000)

The third billing gap covers fee recovery preparation across all three D-46 harm tracks.

  • Documenting the CLRA § 1780 lodestar from the CSLB D-46/C-61 License Check date: SRCC OG-100 product directory search records; SRCC OG-300 system certification review; CEC Title 24 JA8 CF1R-DHW permit file; NABCEP BCSTI inspection report; burn injury emergency department and burn center records; roofing contractor damage assessment and repair bid; LADWP rebate disqualification letter — all fee-petition-eligible from the first CSLB License Check query.
  • Briefing the pure Ketchum multiplier: novelty and difficulty — SRCC OG-100 collector certification directory search methodology (OG-100 product listing database at solar-rating.org; certification validity by installation date; glazing specification analysis from OG-100 test report); SRCC OG-300 expansion vessel undersizing calculation (glycol volume at ambient vs. stagnation; 400°F stagnation temperature for south-facing flat-plate in California summer; proper expansion vessel sizing calculation); Climate Zone 16 freeze protection omission causation analysis; Ketchum v. Moses 24 Cal.4th 1122 (2001); PLCM Group Inc. v. Drexler 22 Cal.4th 1084 (2000).
  • Missouri v. Jenkins fees-on-fees for the fee petition: the time spent preparing the D-46 fee petition — compiling CSLB search records, SRCC OG-100 and OG-300 advisory documentation, NABCEP engineer reports, medical records, utility rebate disqualification documentation, and contractor bids into the lodestar declaration — is itself compensable under Missouri v. Jenkins 491 U.S. 274 (1989); Hensley v. Eckerhart 461 U.S. 424 (1983).

Frequently Asked Questions

Does SRCC OG-100 Solar Collector Certification create mandatory attorney fees against an unlicensed D-46 solar thermal contractor?

No. SRCC OG-100 is a private certification program operated by the Solar Rating and Certification Corporation — it creates no private civil right of action and no mandatory attorney fee-shifting mechanism. However, SRCC OG-100 generates compensable pre-complaint research hours: confirming D-46/C-61 license status at contractors.ca.gov, searching the OG-100 product directory at solar-rating.org for the specific collector model, reviewing the CEC Title 24 JA8 compliance documentation, and retaining a NABCEP solar thermal engineer to document glazing and mounting deficiencies — all fee-petition-eligible under CLRA § 1780 lodestar. PURE KETCHUM: the attorney fee entitlement flows from CLRA § 1780. Ketchum v. Moses 24 Cal.4th 1122 (2001).

What is the difference between D-46/C-61 and C-46 Solar for CSLB solar contractor licensing?

C-46 (Solar) covers photovoltaic electrical solar power systems — PV panels, NEC Article 690 DC/AC wiring, inverters, and battery storage. D-46 (Solar Thermal Systems) under C-61 covers solar thermal flat-plate and evacuated tube collector systems that convert solar radiation to heat for domestic hot water and pool/spa heating — no electricity is generated. A C-46 license does not authorize solar thermal DHW installation; a D-46 license does not authorize any PV electrical work. For § 7028 liability, confirm the C-61/D-46 designation at contractors.ca.gov.

What freeze protection does SRCC OG-300 require for a California mountain solar thermal system?

SRCC OG-300 requires freeze protection adequate for the installation climate zone. For California mountain locations such as Big Bear Lake (Climate Zone 16, elevation 6,750 ft, design temperature −4°F) an open-loop direct system with no freeze protection is wholly inadequate — either drainback (pump stops and loop drains to a reservoir below the frost line), propylene glycol (30% solution rated to −10°F minimum), or thermostatically controlled recirculation is required. An unlicensed D-46 contractor who installs an open-loop direct system at a mountain location without any freeze protection creates a foreseeable freeze burst risk. PURE KETCHUM: SRCC OG-300 is a private SRCC standard; pipe freeze burst and roof damage are recoverable as CLRA actual damages.

Can a LADWP solar water heater rebate disqualification support a D-46 attorney fee petition?

Yes. LADWP's Solar Water Heater Rebate Program requires SRCC OG-100 certification as a condition of rebate eligibility. If an unlicensed D-46 contractor installs a non-OG-100-certified collector and the property owner is denied the LADWP rebate (typically $500–$2,200 depending on system size and installation date), that rebate loss is a direct economic damage recoverable as CLRA actual damages. Combined with roof damage from glazing delamination and the CLRA § 1780 mandatory attorney fee recovery, the rebate disqualification is a standalone quantifiable harm track. Ketchum v. Moses 24 Cal.4th 1122 (2001).

How does Missouri v. Jenkins fees-on-fees apply to a D-46 solar thermal contractor fee petition?

Missouri v. Jenkins 491 U.S. 274 (1989) establishes that attorney time spent preparing and litigating the fee petition itself is compensable as part of the lodestar. In a D-46/C-61 solar thermal matter, the fee petition requires briefing SRCC OG-100 collector directory search methodology, SRCC OG-300 expansion vessel sizing analysis, CEC Title 24 JA8 permit records, and three-track expert documentation — all assembled into the lodestar declaration with time records. Time spent drafting the motion, reviewing the opposition, and arguing the fee petition is recoverable under Missouri v. Jenkins. Combined with the Ketchum v. Moses 24 Cal.4th 1122 (2001) positive multiplier, the D-46 fee petition produces a fully compounded recovery.
