Big dreams for renewable energy often goad people into imagining big solar projects, with acres of panels. But lots of smaller projects are just as likely to add up to big numbers.
Counting solar projects from California and New Jersey (which together make up half the U.S. solar market), the average size of an American solar project is just 34 kilowatts (kW). This squares with findings from Germany, where their 25 gigawatt solar capacity is mostly rooftop projects 100 kW and smaller.
