The 30-degree rule is flexible: While 30 degrees is often cited as optimal, any roof pitch between 15-45 degrees will deliver excellent solar performance, typically within 5-10% of peak efficiency. Don't let imperfect pitch discourage you from going solar.
Typically, a 12V solar panel can produce anywhere from 5 watts to 300 watts. Smaller panels, around 10 to 20 watts, are often used for applications like charging batteries for garden lights or small devices.
