Small-scale solar systems that plug into regular wall outlets are gaining traction in the US as homeowners look for affordable alternatives to traditional rooftop solar installations. These plug-in or balcony solar systems, about the size of a door, have been popular in Europe for years but were previously limited by lack of awareness and utility rules in the US.
However, with the passage of President Donald Trump’s budget-and-policy package, which scraps residential rooftop solar tax credits, manufacturers are seeing increased demand for these smaller systems. Bright Saver, a nonprofit company in California, has seen overwhelming interest in its plug-in solar systems, with over 1,000 units sold since its launch.
The $2,000 system installed on Terrence Dwyer’s backyard deck in Oakland, California, consists of two 400-watt panels, an inverter, smart meter, and circuit breaker. It saves him around $35 per month on his power bill, but he cites reducing his carbon footprint as his primary motivation.
Installing a plug-in solar system requires some homework, including checking the utility’s policies and obtaining necessary permits. Some systems can be self-installed, while others may require an electrician. Bright Saver offers smaller models, including one that sold out in six days.
Utah has recently passed a law exempting certain small-scale systems from interconnection agreements and establishing safety requirements. This move is seen as a positive step towards promoting plug-in solar adoption in the US.
While some questions remain about the savings potential of these systems, companies like Bright Saver and Craftstrom are reporting increased demand despite higher upfront costs compared to European markets. As technology advances and regulations evolve, plug-in solar systems are expected to become more mainstream.
