Solar Panels
I have 2 65w panels connected through a controller. I am testing them with the connection wires disconnected. I am getting 20.5 VOC and 3.5 ISC from each panel. The back of each panel says it shoul...

As has been mentioned before, many factors enter into how much power a solar panel setup will produce. total wattage of the array, latitude, time of year, angle of the array in relation to the sun, quality of the panels (mono crystalline, poly crystalline), age of the panels (most panel will decline a few percentage points each year as they age) Distance from battery bank, size of wire used, type of controller and so on.
I would suggest doing the math. Make a chart of how much power you will need, check your panel output, design your installation so you have the shortest distances from panels to controller, from controller to battery bank, make sure you have the correct wire size for the current produced.
If you are using an inverter (12V DC to 120V AC) decide whether you can use modified sine wave or if you will need a pure sine wave inverter). If you are using an inverter, you will need a sub panel or some form of circuit protection.
The key is to take the time to do all of the calculations and plan ahead for your installation. Good quality electric wiring is expensive and going cheap or trying to save money by using undersized wire is a recipe for disaster down the road. There is a lot of experience and expertise on this forum. Ask the questions before you do an installation. You ill get a lot of good advice!
