Photovoltaic (Solar) Installations are unique from the perspective that both DC and AC electricity are present. Safe work practices are a must when performing this type work. The solar panels are designed to produce voltage when the sun shines on them; simply stated, when we’re working with them, they provide a potential shock hazard. Most of today’s systems are designed to tie-in with the existing power grid. The AC is a source for an additional shock hazard, and “back-feeding” between the two systems is reason for further concern. Proper use of PPE, coordination with local utilities and checklists protect our employees, our greatest objective. Ultimately, per initial expectations, our clients save money by reducing their monthly utility bills.
