Good day, in 2016 I bought two 250w solar panel the next year I went to buy some more panel but the retailer was out of 250w so they suggest some 265w solar panels they explain that they would be equal to the 250w panel that I already had wen I connect them, so I bought 4 of them. So now I want to add more panel, the retailer is saying the don't have any 265w or 250w, they only have 335w and higher. So my question is can those panel be used?
