Going solar #3 – in business, just in time

Once things happen, they happen quickly! After getting the county permits, it took ProVision 3 days to get here to start work, and 1.5 days to finish the install.

The first day they pulled the wires from the meter to the new subpanel in the garage in a long, snaking conduit going under the eaves and then across to the garage, where the inverter is mounted. The inverter is in a closet in the garage:

Then they mounted the conduit for the DC wires up to the panels, as well as the rails that hold the panels themselves:

On the second day, they just installed the panels themselves, pulled some final DC wire, and hooked them up.

Now, the roof looks like this:

Here's the roof now, fully equipped to supply our energy needs, without fossil fuel.

We can’t connect the panels to the grid until the utility has inspected them, but the inverter has a standalone functionality that gives you a backup power outlet if the power is out. We can use that, which seems like a good thing since tomorrow we’re being hit by Hurricane Iselle! I’ve determined that we actually can run the fridge on it, so this will come in handy if the shit hits the fan. Let’s hope it doesn’t come to that.
