The Balcony Solar Craze Has Reached the US. Here’s What to Know Before You Buy
Plug-in solar systems, known as balcony solar, are gaining popularity in the US as an affordable DIY solution to rising electricity costs. These compact devices plug into standard wall outlets to supplement home energy use, offering a cheaper alternative to traditional rooftop installations. While they can significantly reduce bills, their financial viability and legality depend heavily on local regulations, sunlight availability, and energy rates.
- ▪Eleven US states have recently legalized plug-in solar systems, with additional legislation pending in other jurisdictions.
- ▪A researcher in California achieved an 18-month return on investment for his system, though a few years is a more realistic timeframe for most users.
- ▪These systems can generate approximately 150 kilowatt hours of electricity per month, covering about 17% of the average American household's consumption.
- ▪The effectiveness of plug-in solar is maximized in regions with high electricity rates and abundant sunlight, such as California and New England.
