    Do solar panels need an inverter?

    For grid-tied systems, the inverter capacity must be sufficient to meet the AC demand. However, it doesn't necessarily need to match the exact load at all times since the grid will supply additional power if needed. The performance of solar panels varies with temperature, and high temperatures can reduce the panels' output.

    Why are solar inverters sized lower than kilowatt peak?

    Inverters are usually sized lower than the kilowatt peak (kWp) of the solar array because solar panels rarely achieve peak power.
