I put a small flexible light weight one up last year. Secured with steel washcloth line (it doesn’t have glass or anything, just a plastic sheet with cells on it), the city replaced the meter to account for feeding in (not needed, I work home office and use up all of it in my apartment) cost me 600 or so last year, plugs into regular wall socket and has already lowered consumption by about 1/10th which is a solid chunk of money with current prices. I am very happy I get to do something as a renter, even if it will take years to pay for itself.
