Charging 12v batteries with direct connection to 20v solar panels


I want to charge a 12v Sealed Lead Acid car battery off of a solar panel (20v) and then draw about 10-20W of power from it via an inverter (the load).

And what downsides, if any, are there and can I avoid them? Is it a problem hooking up the battery to solar panel without a load?


Thanks!
