Residential rooftops in the US seem to be most commonly tilted between 18 and 34 degrees—pretty much ideal. Even if your roof falls outside of the 15 to 40-degree Goldilocks zone, solar panels can often still produce more than enough electricity to be worth the investment. . The solar panel's best angle determines how much sunlight your panels capture throughout the year, directly impacting energy production and ROI. A correctly tilted system can improve efficiency by 5–10% annuall y, reducing payback time and boosting long-term savings. Start by entering your location in the search box. If you hold the bucket flat during a downpour, you'll catch the maximum amount of water.
