I used Silverline Restoration for my roof - they used GAF architectural shingles with a 50 year life. I have a simple gable roof and they weren’t too pricey ($7500 total). I used Sunpower for my solar panels. As someone mentioned above, they’re a little pricier but they’ve been around since the 80s and their panels have a very low degradation rate. Also they have a 20 year warranty for panels, inverters, roof leaks, and maintenance. Make sure you tally up your electricity usage for a year so that you’re not oversold a bigger system than you need. A few companies I interviewed tried to sell me a system that was way larger than I needed and therefore way more expensive.
