System Details and Green Efforts:
We have a 5.7 kw PV system on our roof that faces due south. The system uses 240w Solar World PV modules coupled with enphase micro-inverters. The system is grid-tied, which means that there are no batteries and that I turn my meter backwards on a sunny day! I designed, purchased, and installed the system (installation with the help of couple of electricians).

We own two electric cars. One is an all-electric Ford Focus. The other is a plug-in hybrid Ford C-Max. We also have a solar water heater for space heating. That system uses 6 solar panels mounted on the side of my garage that heat a 300-gallon tank of water. I use the water to operate hydronic baseboard radiators, and plan to install a loop for pre-heating domestic hot water.
