Power Efficiency Guide

If you've made the decision to go solar, then you Power Efficiency Guide Review/'re probably in process of making sure your roof is solar ready. You will systematically go through inspections to determine the health of your roof, whether it needs replacement of repair and several other considerations. One such consideration is the amount of shading your roof gets.Whether it's caused by trees or even your own chimney, shading directly affects the efficiency of your solar unit and can cost you 20%-40% of the total output of your system.eeping this in mind, here are 5 ways you can help limit shading on your system Bypass Diodes anel Orientation Designing around obstaclesMicro invertersTrim nearby plantationBypass Diodes You may be asking yourself is, "how does the overall output get affected by shading?". Great question. Solar panels are mostly connected in the form of a series. If the first cell/module in the series is being shaded, it will produce less energy. This energy will then travel to the adjacent modules/cells, decreasing your overall output.Good news, Bypass Diodes can prevent this from happening. These can be connected to the cells of your solar panels and will limit the power loss to the shaded areas instead of the entire system. The final output is still decreased as compared to a system that receives no shading but will be considerably higher than the output you would receive had you not installed bypass diodes.Panel Orientation Oddly enough, solar panels can be the source of shadings if they are not installed at the right orientation.
