Netmetering & Solar Sizing Strategies
Netmetering policies will typically define a project size where netmetering is eligible. For example, netmetering may be only available for systems 10 kW and below. Keep in mind that is 10 kW AC and not DC. Solar produces direct current, or DC, and the inverter changes the DC power to alternating current, or AC. The utility company only cares about the AC output and AC output is governed by your inverter’s rating. For example, a 12 kW (DC) solar array connected to an inverter with a rated AC output of 10 kW (AC) would qualify for a netmetering policy with a 10 KW limit. Other utilities may not have a limit, or may allow much higher capacity installations.
There are various electrical losses as power is converted from DC to AC. From your solar array to inverter, overall losses can range from 9 to 15% depending on the efficiency of your equipment, quality of your electrical installation, shading, snow cover, electrical equipment mismatch, and other factors.
There are many variations in netmetering policies from utility to utility. Netmetering can also be a confusing matter. Many solar companies don’t have a good grasp of these policies and their estimate of return on investment (ROI) could be misleading or incorrect.
