As the price per watt of solar pv comes down the trend is to simply add more panels rather than fancier panels or special aiming technologies. That works as long as you have room for panels. Most of us living in puna (the boonies, cheap acreage not good for much else) would fit that category. Granted if you live in the city you are out of luck, but with the way people are paving their whole house lot with either house or parking, even people in town could rack up some kws if PV got cheap enough.
I am gradually getting closer to getting a solar system set up at my place. 720 watts of panels, 200 amp-hr x 48 volt battery bank, 2700 watt inverter. I hope to be able to run a reefer, TV, lights, and misc small electronics such as a phone. I will know soon how it works.
I'll be lucky to get 2 kwh/day here and half of that will go to the reefer.
