As photovoltaic technology moves from 1,500 VDC toward systems rated up to 2,000 VDC, solar cleaning businesses need to review their equipment, working methods and electrical safety training. The consequences of getting it wrong can be fatal. Solar panel cleaners can no longer assume that 1,500 volts DC represents the highest system voltage they may encounter on a utility-scale installation. In March 2025, Sungrow reported that it had deployed a 2,000 VDC photovoltaic system inShaanxi, China. Electrical connector manufacturer Stäubli also offers photovoltaic connectorsapproved for up to 2,000 VDC. Higher voltage solar technology is already a reality, rather than simply a future possibility. This does not mean that every solar farm now operates at 2,000 VDC, or that this voltage has become universally permitted across US installations. It means that cleaning contractors need to verify the electrical characteristics of each site rather than rely on previous assumptions.
