Easily calculate the best solar panel orientation with our free solar panel orientation calculator. Get accurate tilt and direction for maximum energy output.
Do you want to get the most from your solar panels? The secret lies in the way they face. Panel orientation decides how much sunlight hits the surface. More light means more power. Our solar panel orientation calculator helps you find the perfect direction and angle for your panels in seconds.
Think of it like adjusting a chair to catch the warmest sun on a winter morning. When you get the angle right, you enjoy the heat. Solar panels work in the same way.
Solar panel orientation is about two things: tilt and azimuth. Tilt is the vertical angle of the panel. Azimuth is the compass direction it faces. Together, they decide how much solar energy your system collects during the year.
The basic formula for tilt angle is simple:
Tilt Angle = Latitude × 0.76 + 3.1
This formula is widely used for fixed panels. It gives you the best average angle for a year-round setup.
For seasonal adjustment, follow the 20% rule:
Example: If you live at 30° latitude:
Azimuth direction depends on location:
Using the solar panel orientation calculator is super easy.
It’s like having a personal solar installer at your fingertips.
The 20% rule helps fine-tune panel tilt for seasons. In summer, you drop the angle by 20% to capture the higher sun. In winter, you increase by 20% to catch the lower sun.
This trick can improve energy efficiency by up to 10–15% depending on your region.
In most cases:
But, your local conditions also matter. Roof slope, shade, and power needs play a big role.
Think of it like parking your car. You’d park where it gets the most sunlight in winter. Panels should do the same.
Getting the right orientation for solar panels is not rocket science. With our solar panel orientation calculator, you’ll always know the best tilt and direction. Just enter your details and get instant results.
A small adjustment in angle can save you big on bills. Start today, and let your panels work smarter, not harder.
Use the formula Tilt = Latitude × 0.76 + 3.1 and face South (North if in the Southern Hemisphere).
Adjust tilt by ±20% for summer and winter to capture more sunlight.
South-facing in the north, and north-facing in the south.
Yes. Many systems allow tilt changes a few times a year for better results.
