The gap between solar panel rows should be around five to six inches, but it is also recommended that you leave one to three feet of space between every second or third row. This is because maintenance workers need enough room to get on the roof and make repairs whenever necessary. Additionally, local regulations may vary by region or province, so. . Azimuth is the horizontal direction your panels face: 180° = Due South (ideal in Northern Hemisphere). < 180° = East of South. Correct azimuth alignment reduces shading and ensures each row gets sunlight for the maximum number of hours per day. This ensures the panels. . For this purpose, the distances of the rows from each other are determined using the calculations for the angle of incidence of solar radiation for December 23, when the sun is lowest above the horizon. This will help to ensure optimal efficiency and output.
