Balcony solar could help fight rising US utility costs

Something seems wrong with the numbers in this article.

This is the $400 (now $500) balcony solar kit from Bright Saver - it's only 180W: https://www.brightsaver.org/product-page/flex180

From https://www.thegreenwatt.com/peak-sun-hours-calculator/, peak sun hours in California is roughly 6.

If we multiply these numbers together we get about 1080Wh, which is about 1kWh. Electricity rates vary depending on plan, time of day, and baseline usage, but let's assume it's $0.50 per kWH which is on the very high end.

This is only $15/month. But it's balcony solar, which means that the panel is cannot be mounted on the roof, and it's going to be blocked by the very building that it's mounted to, as well as trees and other buildings. So probably a lot less than $15.
