How to troubleshoot low impedance of photovoltaic panels

This is possibly the most common cause of low voltage. Ensure that there are no trees around and that the solar panels are not blocked by shadow at any time during the day. Keep in mind that a solar systems lasts for more than 25 years andtreesgrow over time. Conducting a bi-annual survey of the installation site is a good idea.
