Solar is for 3rd world countries. You spend 20k-30k to save $100/mth. Keep your money in a 4% account and you make that much with no contract and you keep your money. Glass roof tops cause high insurance.

Bonds - solar panels are non-recyclable and make for mountains of waist/trash already, lol. High quality solar panels degrade and .7% every year with a shelf life of bout 20 yr of productivity. Lame
