By monitoring the soiling level, operators can directly see how much energy production is being lost. For example, a reported 10% soiling level corresponds to a 10% energy loss in the PV system.<\/p>\n<p data-start=\"560\" data-end=\"765\">The measured soiling data is transmitted via a 3-wire RS485 bus using the Modbus RTU protocol to data loggers and monitoring units, making integration with SCADA, PLC, or other standard platforms seamless.<\/p>\n<p data-start=\"767\" data-end=\"786\"><strong
