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]
