I mainly use MC4 connectors for my solar panels and I love that they are included in this kit. While 100 watts isn't much, it's an amazing balance of size and performance. I have lighter panels that are larger and produce more power, but compactness is key, this is a good choice. The panels are well made and very efficient. I like the direct cable implementation and the compact solar controller. It's simple and effective. I won't use a controller unless absolutely necessary, but it's nice to know it's there. This is a fairly compact but heavy kit. It's easy 10 pounds.
