Rails or supports underneath panels are commonly spaced between 40 to 60 inches (1000 to 1500 mm) apart, depending on rafter spacing and load calculations. Structural Safety: Poor spacing can cause panel flexing or rattling in strong wind.

Grid-tie inverters convert DC electrical power into AC power suitable for injecting into the electric utility company grid. The grid tie inverter (GTI) must match the phase of the grid and maintain the output voltage slightly higher than the grid voltage at any instant. A high-quality modern grid-tie inverter has a fixed unity, which means its output voltage and current are perfectly lined up, and its phase angle is within 1° of the AC power grid. The inverter has an internal computer that senses the current.
