On average, standard solar panels with a power output of 330 watts measure approximately 5.4 ft x 3.25 ft feet.
For a 13.3kW Solar-Powered Production system, you'll typically need around 30 to 41 (Based on 450W - 330W Panels) solar panels, requiring roughly 525 sqft to 852 sqft. of roof space, depending on panel layout and tilt angle.
It's important to consult with a solar professional to accurately assess your roof's suitability and determine the optimal panel configuration to maximize energy production.
