In winter, the sun is lower in the sky and sunlight is diffused over a larger area, whereas in summer, the sunlight hitting your solar panels is more concentrated..
Solar photovoltaic panels convert a slightly lower proportion of sunlight into electricity in hotter conditions. That is why peak power output generally occurs at midday in April or May..
In winter, panels may produce less due to shorter days and lower sun angles, while in summer they may produce more due to longer days and higher sun angles..
This reduces energy production compared to the summer when the sun is more directly overhead. The number of daylight hours varies throughout the year due to seasonal changes. [pdf]

Solar panel degradation is caused by aging and does not only affect large PV installations, but it is present on every rooftop PV installation worldwide..
Bird droppings and tree sap can accumulate on your panels, blocking out precious sunlight and reducing your energy production. [pdf]
[FAQS about Why do photovoltaic panels always lose power ]
This is primarily due to their lower albedo, which leads to increased heat absorption and enhanced thermal convection between the panels and the underlying roof surfaces..
This is primarily due to their lower albedo, which leads to increased heat absorption and enhanced thermal convection between the panels and the underlying roof surfaces..
However, solar panels are hotter than the air around them because they are absorbing the sun’s heat, and because they are built to be tough, high temperatures will not degrade them. [pdf]
