Two houses, same lot - one solar system

[unheard]

Hello.

 

I"m interested in a solar system that would be capable of covering the vast majority of our electrical needs,

I don't know much about solar and all things electrical.

 

I live in a newly built house located at a distance of approximately 15 m from another, much older house, which is occupied by my parents in law.

Both houses are on the same lot/property.

 

Each house is connected to a separate electrical meter.

The older house is connected via an analog type, while the newer house - via a digital.

Both meters reside on the same pole.

The digital meter supplies electricity to the newer house via an underground cable , while the spinner is connected to the older house via an overhead line.

 

I pay all electrical bills.

 

I'm thinking of installing a hybrid system with batteries that would be big enough to cover both houses electrical needs while still having an option to draw from the utility company during the prolong rainy, overcast weather.

All solar equipment (panels, inverter, batteries) will reside in close proximity to the older house.

 

Questions:

1) How would you configure the connection to the utility company considering the above-described situation with two meters/households?

2) Would it be OK to run an underground cable from the solar station to the second house electrical inlet with an estimated run of 20m?

 

Thank you

Yes and if you want to keep the grid connection with the old meter then you can install an Automatic Transfer Switch at the old house.

You can also choose to have the old meter removed and only feed the old house from the underground cable from your solar inverter.

My inverter is supplying power to our main house and  to the two smaller rental cabins that we have.
