A solar site survey is like a health checkup for your solar project. It's a detailed initial assessment of the property where you plan to install solar panels. This assessment includes checking the roof or ground conditions, measuring available space, analyzing shading, and evaluating the electrical system.
To install a photovoltaic system, the first step is to perform a site survey. When choosing a site for the solar array, consider the following: Ensure there are no shading obstacles throughout the whole day and year. Minimize the length of the DC cables between the PV array and the inverter.
Evaluate the site's electrical infrastructure to ensure it can safely accommodate the solar system. This evaluation includes checking the main service panel's capacity, available circuits, and any potential upgrades needed. When assessing the electrical system, consider the following:
