If you decide to use solar energy, you may be making sure your roof is solar-ready. You will systematically check to determine the health of the roof, whether it needs to be replaced, and other precautions. One of the considerations is the amount of shadow on the roof.
Whether caused by trees or your own chimney, shadows directly affect the efficiency of your solar installation and can reduce your system's total output cost by 20%-40%.
With this in mind, here are 5 ways to help limit coloring on your system:
- Bypass diode
- Panel orientation
- Design barrier
- Micro inverter
- Pruning nearby plantations
You may ask yourself, "How is the overall output affected by shadows?". good question. Solar panels are mostly connected in series. If the first battery/module in the series is being transported, it will generate less energy. This energy is then passed to the satellite module/unit, reducing overall output.
The good news is that bypass diodes can prevent this from happening. These can be connected to the battery of the solar panel and will limit the power loss of the shadow area rather than the entire system. The final output is still ordered compared to systems that do not receive shadows, but is much higher than when the bypass diode is not installed.
Panel orientation:
Curiously, if solar panels are not installed in the right direction, they may be the source of shadows. To prevent this from happening, the installer typically provides a 5-10 meter tilt to the rows in the back row. This not only shields the panels from each other, but also helps to cover less space and allows for the addition of more panels.
Design barriers:
Small obstacles on the roof, such as chimneys, also block part of the system. When you check the roof for solar preparation, be sure to discuss these obstacles with the installer. Typically, solar installers customize the array and how it is placed so that it is not obstructed by roof obstructions.
Micro inverter
Micro-inverters are relatively new to the solar world. Your system will be connected to each solar panel in the array, not to a large inverter connected to the entire system. These not only help to increase system output, but also protect the system from damage caused by high voltage output DC.
Trim the nearby plantations:
This is very obvious, but you won't believe that the number of customers who have experienced system coloring problems is because they haven't trimmed trees. If you are seriously considering solar energy, please do yourself a favor, buy a tree trimmer or hire a landscape architect to help solve this problem. Over the years, remember to pay close attention to their growth.
Now that you know how shadows affect the efficiency of your solar system and how you can prevent it, you can perform a shadow analysis of the roof before going deep into the installation process. If these measures are not sufficient to prevent shadows on your system, consider installing from
