Instead of a single guest, maybe have three short guests or a panel on a specific topic.

They can charge from the grid or from solar.

However the initial capital would be too large (panels + room + GPU investment) for me.

So, your prediction that there would be at least $20k more if everything is included should be accurate.The reason for choosing a JADU is that converting the garage into an ADU would require a separate laundry setup and an additional electrical panel in the main house, which would increase the renovation costs for the main house itself.

Hey how’s it going everyone, I was recently told that a great investment was Solar Farming... now do I have to buy the LAND and THE PANELS ???

Each unit has its own electric panel, gas meter, furnace, water meter.

Any homeowner offered these types of programs associated with allowing homeowners to upgrade their homes with solar or any type of energy conversation improvements with no money down should proceed with caution.  

We needed an upgraded 200amp electrical panel ($5-8k), extended water and sewer for the garage ($5k), built out interior ($7k?)

Electrical panel/updating wiring throughout house3.

Unfortunately, this isn't always an easy relationship.What if you, as a buyer, like a home but despise its wood-paneled walls, shag carpet and lurid orange kitchen?
