Fixed Solar Panel Tilt

Solar panels with a fixed tilt angle.

Fixed solar panel tilt.

For that reason the ideal angle is never fixed. Solar panels should always face true south in the northern hemisphere north in the. The solar panel tilt also depends on when you want the panels to produce the most energy. In a world of rapidly decreasing prices for solar ppas increased power production is critical in helping project owners achieve a viable roi.

We have completed over 2 6 gw of mounting systems for commercial and utility scale projects in canada the u s. The optimum tilt angle for solar panels during winter is calculated by multiplying the latitude by 0 9 and then adding 29. One of these evaluations is choosing between fixed tilt and axis tracking systems in pv solar fields. So why exactly are we seeing this shift from fixed tilt to single axis trackers.

On the picture below is a easy to understand map. In the above. 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. 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.

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. If your solar panels will have a fixed tilt angle and you want to get the most energy over the whole year then this section is for you. Showing with clear colored lines what your best solar panel angle will be depending on where. Tilt and angle orientation of solar panels to get the most from position fixed or seasonally adjusted photovoltaic or thermal solar panels you need to point them in the direction that captures the most sun.

Axsus globally designs engineers and manufactures solar tracking and fixed tilt systems. For panels that you will want to use all year and not have to touch once they are installed you will want to install at a solar panel angle optimized for just that. Axis tracker solar panels there are many design and financial evaluations that go into selecting the correct type of renewable resources in a region. To get the most sun reaching the panel throughout the day you need to determine what direction the panels should face and calculate an optimal tilt angle.

Trackers increase the production of a site by more than 15 to 25 over fixed tilt. For a precise method use the second formula on this page to calculate tilt angle. Otherwise your best bet is to set it at an angle that is optimal for the most prevalent. Subtract 15 degrees from the latitude at your location during summer and add 15 degrees to your latitude during winter.
