Yes it could, and my husband is trying to convince me to do exactly that with ours (we bought extra panels and store them in our house until they prove to be needed).
However I enjoy the light that comes down through the Fantastic; we have an Ultra Breeze covering it, which blocks some of the light but it's still quite bright. So I'm not sure if we need a fourth panel just yet. But if an owner instead covered their Fantastic with a vaulted solar panel, it would eliminate the need for a secondary rain cover, so that's something to think about.
Our solar system is being sized to accommodate my main work computer, which requires somewhere in the neighborhood of 240 watts. We have a DIY lithium upgrade in progress right now, so we haven't done any real-life testing as to whether we can get away with these 3 panels or whether we need more.
