Different sizes of solar panels?

Question:I want to add more solar panels to my array. I have two Kyrocera 55 watt panels now. Do the new panels that I want to add need to be the same brand and wattage? I would like to add panels as I find good deals on them and not be limited to the size or brand so I can save some money.

Answers:
They shouldn't have to be the same wattage, but the probably have to be the same voltage. Find someone selling a competing brand and ask them and then go back to Kyrocera and ask them whether the alternate brand will cause problems and try to work out any confusion between the answers. Go to one of the internet groups on solar energy.
