How much solar

In the end, your solar panels are there to charge your house batteries and not to run anything directly. There should be a voltage regulator in the loop somewhere, should be before the battery connection, or else the solar panels will fry your batteries. With a solar powered house, the panel powers a battery bank that in turn runs the house through an inverter. In bright sunshine, most panels put out a LOT more voltage and power than what they are rated for...hence the need for a regulator. I found that out the hard way a few years ago by hooking up a supposed 12VDC solar panel directly to the battery, without a regulator, on a big generator to keep the battery charged. Came back to do monthly PM and found the battery out of water and dead. Checked the voltage on the panel and it was putting out about 30VDC in bright sunshine.
