The optimum angle varies throughout the year depending on the seasons and your location and this calculator shows the difference in sun height on a month by month.
Optimum roof pitch for solar panels uk.
Pitch and solar pv.
Providing the highest level of solar radiation.
In the uk the optimum roof pitch for solar panels is 30 to 40 degrees.
Elevation is the pitch of your roof in degrees from horizontal.
Depending on the pitch of your roof tracking panels may not be an option for.
Tracking panels live up to their name they track the sun as it moves through the sky each day.
The best angle and orientation for solar panels in the uk the angle and orientation of your roof is a significant factor when considering installing solar panels.
This is due to the fact that the angle of the sun is 50 to 60 degrees which when combined with a 30 to 40 degree roof pitch creates a 90 degree angle.
To get the best out of your photovoltaic panels you need to angle them towards the sun.
A typical two storey house roof in the uk ha a roof elevation of around 30º 40º although there are exceptions.
Shade will also affect your output regardless of the orientation or elevation.
The angle of your roof actually has less impact on solar panel performance than the direction your solar energy system faces.
Solar panel angle by zip code.
Pv panels output will drop off beyond these figures.
Your life would be much easier if you could just find out what angle is the optimal solar panel angle in your city or county.
Many roofs are going to have slopes between 30 and 40 degrees which means that solar panels can lie flush against the roof and produce enough electricity for attractive returns.
If you are trying to install solar panels on a steep roof it may not be possible to place panels at the optimal tilt with traditional racking systems.
Regardless of where you live or the tilt of your roof adopting solar power provides significant savings.
Fixed panels are stationary and remain at the same pitch throughout the day and year.
Fixed or tracking solar panels.
The ideal angle is about 30 degrees off the horizontal simply because this allows the panels to extract more from the sun in the morning and the evening whilst still making the most of the mid day sun.
As well as the orientation the angle at which the panels are pitched is important.
For example a solar panel placed flat onto a west facing wall will produce about half the amount of electricity compared to being placed at a 30 degree angle on a south facing roof.
The table below features a solar panel angle by zip code for at least one city from every state.
Optimal electricity production occurs when solar panels face south at a tilt equal to 30.
Optimum angle for solar panels.
For example if you reside.
The ideal angle for solar panels in australia is usually equal to the latitude angle of the location of the property.
