I did really rough math and a hypothetical 200W panel getting 100% sun for 5 hours per day (1 kW/hr) would net you a whopping ~$9.30 in savings per month. We're paying something like $0.31 per kW/hr in NYC and it's a lot of money right now.
- Aurornis 6mo agoDid your calculations account for the suboptimal angle of the panels in most balcony solar setups? Most calculators assume the panels are at an optimal angle or on a roof pitch, not vertical like the image in the article. A setup like the image in the article is going to get much lower than optimal efficiency because the panel is mounted vertically. She could be netting closer to $2-3 dollars per month or even less depending on which way she’s facing.
