I really don't understand why most people here act like this is some weird unproven and unsafe technology. This is literally a solved problem. They are everywhere in Germany and it's no issue.
The inverters follow the grid AC and shut off their output if they are disconnected or unplugged, so the plug is never "hot". The power they input into your home wiring/the power grid is limited to 800 Watts as to not overload any installation. And the power meters know not to run backwards if you happen to feed power into the grid. Most can even meter how much power you fed in total (you're not going to get paid for it, though)
If you want, you can add battery storage that follows the same rules but lets you save excess power during the day to feed into your home at night or during demand spikes (washing machine, ...).
The setups are dirt cheap (often 200 - 300 EUR for an inverter and 800 - 1000 W(peak) of solar panels) and pay for themselves in about 1-3 years in saved electricity costs.
