I've been trying to build products to start my own solar company. A common issue with solar panels is dust accumulation, which reduces the already low efficiency even further. I've been working on creating Solar powered Street Lights, hypothetically with vent design that avoid/reduce dust accumulation. My major being in Electronic Engineering , I've the circuit and connections part covered.
Is it possible to design vents along the solar side of such lights that could use air stream over highways that prevents dust accumulation so as to reduce the need of regular maintenance?
