I use one 235w module.
I recommend a good quality controller like Morningstar.
I bought two 6v GC2's at Sam's club. They work fine. If you want better, buy Trojans for an additional $75. I also have another 100AH in AGM.
I run a small electric dorm fridge and 1202V entertainment devices. My furnace, alarms, water heater use no power. I have a water pump lights and fans that use 12V. Calculate your usage in watts or amps and allow for a cloudy day.
Wind turbines are impractical unless parked for a season. I have a small wind setup at my house. It doesn't make enough power to do much.
Solar Blvd has good pricing for modules. E Bay and Amazon can also be good. The Renogy modules w/free shipping can be a good bargain.
