For example if you are seeking to maximise solar generation during winter months be it for an off grid system or higher energy consumption levels you would ideally want to angle your panels at a greater tilt for maximum exposure to the low winter sun.
Best angle for solar panels in winter.
If you want to improve your winter performance you would angle your photovoltaic panels towards the winter months in order to get the best performance at that time of year.
In this way at noon the panels will be perfectly perpendicular to the sun s rays.
While you can use solar panel trackers to keep them at the optimum angle at all times the costs and complications involved aren t worth it in most cases.
Solar panels with a fixed tilt angle.
Corey wood march 6 2019 at 2 15 pm solar panels need sunlight to produce power so if your solar panels are covered in snow they will not generate electricity this statement is not actually true.
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.
The violet line is the solar energy per day if the panel is fixed at the winter angle discussed below these figures are calculated for 40 latitude.
As a general rule of thumb keep in mind that the panels need to be more vertical during winter to face the lower sun directly and more tilted towards the ground during summer to face the higher sun.
In 2015 the northern alberta institute of technology nait completed a 3 year long side by side study comparing snow covered panel performance with snow cleared panel performance.
The ideal angle for your solar panels can vary depending on your solar objectives.
Here two simple methods for calculating approximate solar panel angle according to your latitude.
While the sun is in a higher position in the sky during the summer and lower position during the winter it has an average position right in between the two seasons.
Therefore the best angle for your solar panels is the one that allows the panels to get the most direct perpendicular light.
At some places as much as a vertical tilt of the panels is needed to get the maximum output during wintertime.
Calculating the ideal angle for your solar panels is not that difficult.
Solar panels on a shallow roof capture more sunlight during the summer season whereas solar panels on a steep roof will produce more power during the winter.
During winter the sun is lower and to catch more of its light the best solar panel angle would be more tilted.
Optimum angle differs during winter months.
