For example, a module rated at producing 20 watts and is described as max power (Pmax). 2V under full power, and the rated operating. . The grid-connected system consists of a solar photovoltaic array mounted on a racking system (such as a roof-mount, pole mount, or ground mount), connected to a combiner box, and a string inverter. The inverter converts the DC electrical current produced by the solar array, to AC electrical current. . Estimate the ideal inverter size for your grid-tied solar system based on solar array capacity, system losses, and inverter loading ratio (ILR). Formula: Inverter Size (kW) ≈ (Array Capacity ÷ ILR) × (1 - Losses%) × Efficiency. The most common is a "LOAD SIDE" connection, made AFTER the main breaker. This way you attempt to eliminate all or part of your electric bill.
