DIY solar/worth the cost?

Do a 22 panel install on the house south facing roof first, then the east facing garage dormer and lastly the shop.

A 22 panel system is easy, quick, inexpensive and gets you going.

The Enphase M250 microinverter is a perfect match for a 280-300 watt panel. About 15% more expensive, but you get more kWhrs. But you cannot use 72 cell PV panels - the M215 and M250 can only use 60 cell panels.

The Envoy monitoring system can do up to 500 panels at different locations.
