Calculating the optimal solar panel angle as a rule of thumb solar panels should be more vertical during winter to gain most of the low winter sun and more tilted during summer to maximize the output.
Solar panel inclination uk.
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.
If you are using a compass to orient your panels you need to correct for the difference which varies from place to place.
To get the best out of your photovoltaic panels you need to angle them towards the sun.
Welcome to another entry in our ongoing solar 101 series.
Solar panels should always face true south if you are in the northern hemisphere or true north if you are in the southern hemisphere.
Elevation angle and azimuth angle commonly shortened to angle and azimuth for brevity.
The optimum angle varies throughout the year depending on the seasons and your location.
Therefore in london which has a latitude of around 51 degrees solar panels should ideally be mounted at an angle of approximately 65 degrees.
Since solar panels are more productive when the sun s rays are perpendicular to their surfaces the certainly best orientation is the one directly true south azimuth angle 180.
Today we re going to explain how to mount your solar panels to get the most energy from them.
Let s start with two key terms.
On the contrary in the countries of the southern hemisphere such as south africa and australia the best orientation is true north.
In marseille for conventional thermal energy 4m of panels are necessary for a typical home s hot water needs 200 l at 45 c and the best inclination of the panels is between 50 and 55.
For the best results solar panels should be oriented towards the south.
In general photovoltaic solar panels should be mounted at an angle of 10 to 15 degrees plus the site s latitude.
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.
This way you could adjust the tilt angle and direction of the solar panels to an optimal level.
The vertical tilt of your panels.
This is because the sun is always in the southern half of the sky in the northern hemisphere.
Here two simple methods for calculating approximate solar panel angle according to your latitude.
This solar angle calculator tells you by location the optimum angle to get the best out of your system.
True north is not the same as magnetic north.
