My point was to get useful power at a stable voltage you need some battery like components to buffer the inconsistent power delivery of a solar panel so most of the time you see a actual battery involved.
Without any batteries you typically need to way over panel and still have some caps involved. My parents have a 7kw solar system grid tied no batteries with a 1500w emergency outlet that runs when the grid is down. Works ok but if enough clouds go over it just shuts off the inverter needs a lot of excess to maintain a stable 120v output and it has rather large filtering caps.
