Solar PV & Rooftop Electrical Safety VR training.
Rehearse rooftop PV isolation, DC arc and fall-protection discipline on a virtual array where a string stays live in daylight and the consequence is scored, not real.
Solar PV & Rooftop Electrical Safety VR training
DrillXR Solar PV and Rooftop Electrical Safety trains workers to service photovoltaic arrays on a virtual rooftop where, unlike most electrical work, the source cannot simply be switched off. The simulation reproduces the hazards that make PV uniquely deceptive: a DC string that stays energised whenever there is daylight, a DC arc that does not self-extinguish the way an AC fault often does, falls from a rooftop or fragile-surface array, and shock during work on inverters and combiner boxes. Inside the headset the worker surveys the array and the roof access and fall-protection setup, isolates both AC and DC and identifies the circuits that remain live, proves dead and confirms the string state before working, services the inverter or combiner box with the correct PPE, and restores, re-tests and records the isolation. The lesson the headset drives home is that a panel in sunlight is always a live source.
Rooftop solar combines electrical and height risk, and India's framework covers both. The Electricity Act 2003 and the Central Electricity Authority safety regulations govern safe working on the installation, the Building and Other Construction Workers Act extends fall-protection duties to rooftop work, and a site rooftop-access and electrical permit-to-work procedure ties the two together. The common and dangerous misconception is that opening the AC isolator makes the system safe, when the DC side between the panels and the inverter remains live in daylight. A briefing rarely overturns that intuition. DrillXR lets a technician isolate AC, discover the DC string is still live, and prove the state before touching it, so the daylight-means-live discipline is built before they are ever on a real roof.
Why train solar pv & rooftop electrical safety in VR
Solar PV risk is counter-intuitive, and counter-intuitive hazards are exactly what classroom theory fails to fix. A worker who knows AC isolation cold can still treat a PV array as dead once the inverter is off, because nothing looks live, yet the DC string is energised by the sun regardless of any switch. VR makes the invisible visible: the trainee isolates the AC side, sees the DC string remain live, and learns to prove the state rather than assume it, and a DC arc that refuses to self-extinguish can be shown safely in the headset. The combined height risk means the trainee also experiences the rooftop exposure and fall-protection setup in the same session. Recreating a live DC fault or a rooftop fall to teach someone is impossible to do safely; DrillXR reproduces both hazards and their consequences with no real exposure.
Inside a solar pv & rooftop electrical safety session
A session places the trainee on a virtual rooftop with a fault to investigate on a PV array. They begin by surveying the array, the roof access and the fall-protection setup, establishing anchorage and edge protection before moving onto the surface. They isolate the AC supply and then the DC, and crucially they identify that the string between the panels and the inverter stays live in the daylight; treat the array as dead after AC isolation alone and the simulation registers the live DC hazard. They prove dead and confirm the string state at the point of work before touching a conductor. Working the inverter or combiner box, they use the correct PPE and insulated tooling. A DC arc is demonstrated if a live connection is broken under load. The run closes as they restore, re-test and record the isolation, with the fall-protection used throughout.
Scoring & certification
Each attempt is scored across the procedure: array and fall-protection surveyed, AC and DC isolated with live circuits identified, proved dead and string state confirmed, inverter or combiner box worked with correct PPE, and the isolation restored, re-tested and recorded. The decisive failures are captured explicitly, treating the array as dead after AC isolation only, working an unproven DC conductor, breaking a live connection under load, or a fall-protection lapse on the roof. Per-step weighting yields an overall competency outcome, and a passing run issues a dated certificate against the worker's record. Results stream over xAPI and SCORM to the LMS and the DrillXR compliance dashboard, where an HSE manager can confirm only competent staff are cleared for rooftop PV work and can evidence both the electrical and the work-at-height competence to an inspector.
Deployment on your site
Solar PV and Rooftop Electrical Safety runs on Meta Quest, Pico and PC-VR and launches in kiosk mode, so a headset at the depot or training room boots straight into the module for the next technician. The scenario is configurable to the customer's installations: the array layout and roof type, the inverter and combiner-box arrangement, the AC and DC isolation points, the fall-protection anchorage available, and the site rooftop-access and electrical permit-to-work procedure can be mirrored so training matches the systems crews actually service. A fleet of headsets is managed from one console with completion data feeding the central dashboard. For power and construction operators rolling out rooftop and ground-mount solar, this delivers consistent, auditable PV competence across sites before anyone is cleared onto a live array.
