Solar installation crews spend full days on south-facing rooftops and ground arrays in direct sun — often at sites in the Inland Empire, Central Valley, and San Diego East County where summer temperatures regularly top 105°F. Cal/OSHA §3395 applies to every solar crew in California, and inspectors have increased enforcement in the renewable energy sector. HeatLog monitors each job site automatically and builds the documentation before you need it.
HeatLog monitors the weather at each solar job site, triggers the checklist when thresholds are crossed, and saves a timestamped record that stands up to a Cal/OSHA inspection.
Every morning at 6am, HeatLog checks the NOAA National Weather Service for each job site address. Solar projects often move between addresses — add each site separately and HeatLog monitors them all with the same government-source data an inspector can verify.
Your crew lead gets an email alert with a one-click compliance checklist: shade access, water availability, cool-down breaks, buddy system. At high-heat installations (95°F+), mandatory cool-down periods are logged. Takes under 60 seconds to confirm.
The confirmed record is saved with a server timestamp that cannot be backdated. Download your full monthly audit log as a PDF and hand it to an inspector — or email it directly from the dashboard to your safety officer or general contractor.
The solar industry has grown rapidly in California — and Cal/OSHA enforcement has kept pace. Every trade working outdoors on solar projects falls under §3395, not just the panel installers themselves.
Rooftop panel installation on homes across Southern California, the Central Valley, and the Bay Area. Crews work in direct sun from mid-morning through late afternoon during peak installation season, which coincides exactly with peak heat season.
Large-scale commercial installations on warehouses, retail centers, and industrial rooftops. Commercial projects often run longer days and involve more workers, increasing both the exposure and the documentation requirement.
Utility-scale ground arrays in the Mojave, San Joaquin Valley, and desert regions. No shade structures, sustained extreme heat (110°F+ in summer), and large crews — the highest heat-exposure work in the solar industry.
Battery energy storage installation is increasingly paired with solar projects. Outdoor installation of BESS containers and related infrastructure is covered under §3395 the same as panel work.
Outdoor installation of commercial EV charging stations — a fast-growing trade in California's electrification push. Often installed in open parking lots with no shade, in summer conditions that cross heat thresholds daily.
Electricians handling inverters, disconnects, and conduit runs on solar installations. Subcontractors are responsible for their own workers' documentation — being on a general contractor's site doesn't transfer the compliance obligation.
Add each address as a separate job site in HeatLog — the platform supports unlimited sites at a flat $49/month. Each site gets its own NOAA weather check, its own alert email, and its own compliance record. When a crew finishes a project and moves on, you can set an end date on that site so it stops generating records. You get one consolidated compliance log per site, with each month's PDF available for download or email.
Yes — each employer is responsible for their own workers under Cal/OSHA. If you're the subcontractor and your workers are on site, you need your own records. A general contractor's heat safety plan doesn't cover your employees. Cal/OSHA can (and does) cite multiple employers on the same job site for the same heat violations. Maintaining your own HeatLog records means you can demonstrate compliance independently, regardless of what the GC did or didn't document.
Yes. California's heat illness regulations apply to all employers with outdoor workers — there's no minimum employee threshold or business size exemption. A 2-person sole proprietor with one helper is covered the same as a company with 200 crews. Cal/OSHA particularly targets smaller employers in enforcement sweeps because they're statistically less likely to have documentation in order. At $49/month, HeatLog is designed to be affordable for exactly this situation.
