 Trenching for the wire from PV array to the house.\\
-House Side Wiring
+==== House Side Wiring ====
 The TVA requires what is referred to as a line or supply side connection, which means that the solar feed connects to the grid at their usage meter. Many parts of the country use what is called a load side connection. This would require running the cables from the solar array into the house breaker panel. Line side was much easier for me. I had to buy a meter base for the solar supply meter, and a manual disconnect switch. The wiring from the array runs through the buried conduit into the solar supply meter; into the manual disconnect switch, and then over to the usage meter. All boxes were connected with grounds and to a ground rod.

 When the connection day finally came, it was cold, snowing, windy and completely overcast, yet the system put out enough power to successfully complete the test.

-With the Enphase Enlighten monitoring system, anyone can go to  My Enphase Web Page  and see current and historical production. As of this writing, it's only been connected for a month of short and often cloudy winter weather. Even so, it is averaging just a little under our usage. I feel confident the longer sunny days of summer will create more power than we are using.
