Spent $500 on solar panels for my balcony in Portland - worth it or not?
Honestly, I dropped $500 on those plug-in solar panels for my apartment balcony to cut my electric bill. So far after 3 months, I'm saving about $15 a month, which means it'll take over 3 years to break even. But the city gave me a $100 rebate, so that helps a little. Anyone else try small solar setups and see real savings or was it just a gimmick?
