Continuing education courses must be approved by TDLR—many providers offer online solar PV specialist courses.

Renewal fees are $350-$500 depending on license class. You must maintain general liability insurance ($1 million minimum) continuously—lapses void your license. If you miss the renewal deadline, TDLR charges a $150 late fee and may suspend your license, making it illegal to perform electrical work.

Operating as a solar installer without a valid Texas electrical license is a criminal offense under Texas Occupations Code § 1305.351. Penalties include fines up to $10,000 per violation, potential jail time up to 180 days for first offense, and up to one year for repeat violations. The Texas Attorney General's office and TDLR actively prosecute unlicensed contractors through cease-and-desist orders that prohibit further work.

Violations are discovered through complaint investigations (homeowners report unlicensed work), building permit audits, and TDLR compliance inspections. Performing electrical work without proper permits in Corpus Christi incurs fines of $500-$2,000 per day of violation and mandatory project stoppage by the Building Official. Unpermitted installations may not pass final inspection or interconnect with the electric utility, rendering the system non-operational.

Insurance implications are severe: homeowner liability claims for fires or electrical failures caused by unlicensed installation are often denied under "negligent installation" exclusions. Property insurance may be voided if damage occurs on an unpermitted system. Utility companies (City Public Utility Board, AEP Texas) will refuse interconnection of systems installed by unlicensed contractors, preventing net metering benefits. Contractors face civil liability for property damage, personal injury, and breach of contract claims. Texas courts have awarded damages exceeding $50,000 in cases where unlicensed solar work caused fires or electrocution.
