The corp 138 final bundle equips the PV panel installer of the Comarca Lagunera (Torreón, Gómez Palacio, Lerdo, Durango, Saltillo, Monclova). Hard hat with industrial chin strap, UV 400 protective glasses, dielectric gloves rated for 1000V, technical backpack with document and tool pockets. The CFDI 4.0 invoice goes under USO CFDI D02 or I08 with 16% national IVA. Delivery runs from the regional warehouse in Torreón with 1–2 day transit for Durango, Coahuila and Chihuahua.
The Comarca Lagunera (Torreón-Gómez Palacio-Lerdo conurbation) is the region with the highest solar irradiance in the country, averaging 5.5 to 6.0 kWh/m²/day according to NASA SSE and CENACE. The PV cluster operates more than 25 solar integrators installing distributed plants on industrial and residential roofs, with more than 850 MW of installed capacity accumulated over the past 5 years. The solar corporate operating in Comarca Lagunera runs crews of 4 to 8 installers per site, with constant rotation between projects.
The PV installer's work demands PPE certified under NOM-017-STPS-2008 and NOM-009-STPS-2011, UV 400 glasses for direct sun exposure of 8 to 12 hours, class 0 (1000V) dielectric gloves for cable and string box handling, and a technical backpack that supports transport of hand tools (drill, torque wrench, multimeter, clamp meters). The corp 138 final bundle covers the initial issue.
The solar integrator with Comarca Lagunera presence invoices consolidated from its Torreón fiscal domicile (usually colonia Centro, Ejido la Compañía, Sector Naval or Cd Industrial). The invoice breaks down per crew, site and period. Deductibility runs under Article 27 LISR as integrator operating expense, with supporting documentation: installer list signed by site supervision and current tax certificate.
The solar corporate runs a site calendar shaped by the dry season (October to May, higher installation demand) and rainy season (June to September, lower site pace). Delivery to site runs via specialised carriers with 1–2 day transit for Comarca Lagunera, Durango, Coahuila and Chihuahua. For sites in Sonora, Baja California and Nuevo León, transit extends to 2–4 days.
The kit ships in a rigid box sealed with the corporate stamp and installer folio, identified with installer's name, RFC and crew. Each piece carries engraving of the corporate logo for inventory control and site documentary traceability.

The solar corporate with more than 10 simultaneous sites in Comarca Lagunera issues a single consolidated invoice with per-crew, site, installer RFC and kit-count breakdown. Deductibility runs under Article 27 LISR as integrator operating expense, with supporting documentation: installer list signed by site supervision and current tax certificate. The CFDI 4.0 invoice attaches to the site file.
For solar companies reporting ESG indicators (CO2 reduction, renewable energy generated, operational sustainability), the corp 138 final bundle provides evidence of commitment: dielectric gloves reduce accidents, UV 400 glasses prevent eye damage, the certified hard hat protects the installer. The CFDI 4.0 invoice with certified-PPE breakdown serves as supporting documentation for the ESG spend reported in the sustainability report.
The Comarca Lagunera solar corporate runs high season (October to May) that demands maximum headcount, transition season (June, September) with regular headcount, and rainy season (July to August) with reduced headcount. Crew turnover is high: the corporate reports 10% to 15% monthly turnover among installers, higher in the rainy season due to temporary site suspension.
The annual contract with safety stock and replacement within 5 business days covers the continuous flow of crew hires and departures. Delivery is scheduled to match site peaks: October (high-season start), February (mid-season), April (end-of-season prep). For urgent deliveries (crew starting the next day), we run a minimum batch of 5 kits with 8–10 business day production time.
Production runs 15 to 20 business days for series of 30 kits or more, with 20 to 25 days for series above 100 kits. Delivery to site runs via specialised carriers with 1–2 day transit for Comarca Lagunera, Durango and Coahuila.
