It’s a 6kW Diesel generator located by the bodega. Yeah, you can hear it in the B&B but it is not very loud. It’s been there for a while but I just installed the (manual) transfer switch. (Automatic is on the agenda but, for now, this is OK.
On the “to do soon” list is add four solar panels (that we already have) and an inverter. That won’t run the whole place but it will cover lights, fridge, and stove in the owner unit, internet, computer and lights in the terrace and hot water. And it should pretty much reduce the electric bill to zero.
