Container solar panels come in various sizes, but the standard dimensions often used are 1.6m x 1m, with a weight of approximately 40 kg. The output varies depending on the specific model and technology employed, usually ranging from 250 to 400 watts, depending on efficiency and design.
[pdf] Individual solar panels come in a lot of different shapes and sizes, but generally speaking, they're about 3 feet by 5 feet, or about 15 square feet per panel, according to Pamela Frank, vice president of Gabel Associates, an energy consulting firm.
[pdf] A typical 100-watt solar panel is 41.8 inches long and 20.9 inches wide. It takes up 6.07 sq ft of area. If you have a 1000 sq ft roof, and you can use 75% of that roof area for solar panels, you can theoretically put 123 100-watt solar panels on a 1000 sq ft roof.
