I'm wondering if there's an economical edge with 250 watt panels. All of these installers that I have spoken with are seeming to only use 250 watt panels but my brother who is an electrician explained that there are all types of wattages for different panel types. Does anyone have any experience with the different w values? I want to make sure I get enough power for my household energy consumption

The difference between a 200W and 250W solar panels is that a 250W solar panel has a higher power output, which means that, given the exact same conditions, a 250W panel will produce more energy than a 200W panel.

A 250W panel is not necessarily better than a 200W panel, however. Your primary concern should be that you get a system that has a big enough overall output to power your home. A system that has 12 solar panels rated at 250W can produce the same amount of power as a system that has 15 panels rated at 200W (12 x 250W = 3,000W, 15 x 200W = 3,000W). At that point, it's a question of which design you like more, and which system comes at a better price.

For a system of 5000W or 5KW, you can use 20 panels of 250W or 25 panels of 200W. So a system with 200W panels will take more space if you plan to install it on the roof.
