Location-Specific Tilt Angles
Our calculator uses your latitude to determine the best tilt angles. For example, in Karachi East (latitude 24.86°), the year-round angle is approximately 24.86°. However, we go beyond this rule of thumb by applying advanced formulas:
- Year-Round: Latitude × 0.76 + 3.1
- Spring/Fall: Latitude × 0.98 – 2.3
- Summer: Latitude × 0.93 – 21
- Winter: Latitude × 0.875 + 19.2
Seasonal and Monthly Adjustments
The sun’s position changes throughout the year—higher in summer, lower in winter. Our calculator provides:
Seasonal Angles: Four distinct angles to adjust your panels quarterly.
Monthly Angles: Twelve angles for fine-tuning each month, ideal for those with adjustable mounts.
For example, in winter, a steeper angle (e.g., 39.86° in Karachi East) captures more sunlight when the sun is lower, while a flatter angle (e.g., 9.86° in summer) is better for higher sun positions.
Sun Direction and Azimuth Considerations
While our solar panel direction calculator focuses on tilt, proper orientation (azimuth) is also crucial. In the Northern Hemisphere, panels should face true south (180° from north) to capture the most sunlight throughout the day. Our tool assumes this orientation but encourages you to check for obstructions like trees or buildings that might cause shadowing, which can reduce efficiency.
Interactive Visualizations
Each season comes with a canvas visualization showing:
- The solar panel tilted at the recommended angle.
- The sun’s position and rays, illustrating how sunlight hits the panel.
- The ground level for reference, helping you understand the tilt in a real-world context.
Use Cases
Optimize your rooftop solar setup for maximum energy production, whether you have a fixed or adjustable mount.
Adjust portable solar pv panels angle calculation on the go to ensure you’re always capturing the most sunlight, no matter where you park.
For remote cabins or tiny homes, fine-tune your panels to meet your energy needs year-round.

What is the Purpose of the Solar Panel Tilt Angle Calculator?
The purpose of our calculator is simple: to help you position your solar panels at the ideal tilt angles by city or zip code, maximizing energy production. The angle at which your solar panels are tilted directly impacts how much sunlight they capture. A flat panel (0° tilt) reflects most sunlight, while a properly tilted panel ensures sunlight hits the surface perpendicularly, boosting absorption and efficiency. Our calculator takes the guesswork out of this process by providing precise tilt angles for your location, whether you’re optimizing for year-round performance, seasonal adjustments, or monthly fine-tuning.
How to Use the Solar Panel Tilt Angle Calculator
Using our calculator is straightforward and takes just a few steps:
Enter Your Location:
Type your zip code (e.g., 90210) in the “Enter Zip Code” field, or click “Use My Location” to automatically detect your coordinates.Our tool uses the OpenCage API to fetch your latitude, ensuring accurate results.
Calculate the Tilt Angles:
Click the “Calculate Tilt Angles” button.
The calculator will process your location and display the Best Summer Tilt Angle, Best Winter Tilt Angle, and year-round angles, along with seasonal and monthly recommendations.
View Your Results:
Year-Round Angle: A single angle optimized for consistent performance throughout the year.
Seasonal Angles: Four angles for Spring, Summer, Fall, and Winter, ensuring you capture the most sunlight as the sun’s position changes.
Monthly Angles: Fine-tune your setup with monthly tilt angles for maximum efficiency.
Visualizations: Check out the canvas images showing how your panels should be tilted for each season, complete with sun direction and panel orientation.
Adjust Your Panels:
Use the provided angle finder to tilt your panels manually, or set up an adjustable mount to change the angle seasonally or monthly.
Benefits of Using the Solar Panel Tilt Angle Calculator
- Maximize Energy Production: Proper tilt angles can increase energy output by up to 7–8%, as seen in studies from Chandigarh, India.
- Cost Savings: More energy means lower electricity bills and a faster return on your solar investment.
- Seasonal Optimization: Adjust your panels to capture more sunlight in winter (when the sun is lower) or summer (when the sun is higher).
- User-Friendly: No technical expertise needed—our tool does the math for you.
- Eco-Friendly: Harnessing more solar energy reduces your carbon footprint and reliance on fossil fuels.
People Also Asked (PAA)
How Do You Calculate Solar Tilt?
Enter your location (zip code or current coordinates) into our calculator. It uses your latitude to compute the tilt angle with formulas like Latitude × 0.76 + 3.1 for year-round optimization, adjusting for seasonal and monthly variations.
What is the 20% Rule for Solar Panels?
The 20% rule suggests that for every 1° your tilt angle deviates from the optimal angle, you lose about 0.2% of your energy output. Our calculator ensures you stay as close as possible to the ideal angle to minimize losses.
How Do You Find the Right Angle for Solar Panels?
Use our calculator to input your location, and it will provide the best angle based on your latitude and the time of year. You can also manually measure your panel’s tilt with a protractor or inclinometer to ensure it matches the recommended angle.
How Much Difference Do Tilting Solar Panels Make?
Tilting panels to the optimal angle can increase energy production by 7–8% annually, as shown in studies from Chandigarh, India. Even small adjustments can make a significant difference over time.
What Direction is True South?
True south is 180° clockwise from true north in the Northern Hemisphere. Use a compass or digital app to ensure your panels face true south for maximum sunlight exposure throughout the day.
What is the Rule of Thumb for Solar Panel Tilt?
The general rule is to set your tilt angle equal to your latitude for year-round performance. However, our calculator improves on this by providing seasonal adjustments, which can increase energy output by up to 0.71% annually.
How to Calculate the Tilt Angle?
Our tool automates this for you, but manually, you can use: Year-Round = Latitude × 0.76 + 3.1; Summer = Latitude × 0.93 – 21; Winter = Latitude × 0.875 + 19.2. Enter your latitude into these formulas to get your angles.
How Much Should Solar Panels Be Tilted?
This depends on your location and goals. For example, in Karachi East (latitude 24.86°), a year-round tilt of 24.86° is ideal, but you might use 9.86° in summer and 39.86° in winter for seasonal optimization.
What is the Optimal Tilt Angle?
The optimal tilt angle varies by location and season. Our calculator provides the most accurate angle for your specific needs, typically outperforming the latitude rule by 0.71% in annual energy production.
