Interested in investing in solar, but at a smaller level than some multi-megawatt facility? Then check out Mosaic. I’m not affiliated with them and am not a current investor, but it’s a neat business model that I thought I’d pass along. They treat your investment like a loan, to fund smaller scale solar energy projects. Most projects listed are returning 4.5%, so it’s not some get rich quick scheme, but not a bad investment all in all.
