Several measures can be taken to mitigate voltage drop in solar energy systems: Proper Wire Sizing: Choosing wires with adequate gauge size based on the current load and distance to minimize resistance and voltage drop.
When shading occurs under load, the power produced by the solar panel drops because the panel cannot produce its total energy capacity. The load has little to do with the decline because the power level from the panel was already low. Is the Temperature Playing a role in Load Capacity?
Issues that can cause a solar panel to not perform at peak capacity include: Fluctuations in lighting to the panel, such as dawn and dusk, cloud cover, storms, and debris. Corroded connections between the panel and the inverter. Age — panels only last for so long before they naturally degrade.

As the temperature rises, the output voltage of a solar panel decreases, leading to reduced power generation. For every degree Celsius above 25°C (77°F), a solar panel''s efficiency typically declines by 0.3% to 0.5%. This decrease in efficiency can be significant in regions where temperatures rise dramatically during the day, such as deserts or tropical areas. …
For example, my solar panel has a Max. System Voltage rating of 1000 Volts, which is the common rating for most solar panels.
