So solar panels produce DC current, no conversion actually happens when sunlight is generated as electricity.
The DC current is then converted to AC as it is efficient in the electrical grid for long distances. However it is also used at home and majority of devices (hardly at least) don’t use AC as it gets converted to a safer DC current. This is especially important for electronics and battery recharging. When conversion happens, majority of that energy is lost as heat which you would find in the charging brick. In addition, with smartphones and EVs, wouldn’t direct DC be more efficient and quicker to charge than converting it back to DC. [Proponents claim that it would be beneficial if buildings had a ‘AC-DC converter box’ near a switchboard.](https://www.youtube.com/watch?v=hF_A4sp7nM8) (should mention that this is not a very credible source but others also claim similar stuff with DC)
So as I said before, why is AC forced as the current for homes instead of direct DC. Only current that needs to be exported to the grid would benefit from AC conversion. I couldn’t really see any answer to this with solar on mind. They will say AC is used for powering things while the other sites claim that AC burn devices if used.

A power inverter modifies DC power to AC power. AC power is what the power grid uses. Without the inverter, the solar panels are essentially useless on the power grid
