The first thing to keep in mind is that solar panels need light not heat! In winters the quality of light is still the same, the quantity is reduced because of shorter days. On snow days or blizzards, panels can get covered by snow but they are designed and installed in such a way that it clears off on it’s own. In major cities like Karachi, Hyderabad, Multan, Lahore and Islamabad we do not have to worry about snow reducing solar production.
A Balancing Act
Lets visit the basic of physics for a moment: “lesser the temperature of electrical components the more efficient it becomes”. This is the general principal why computers/laptops have such a defined cooling system. Following the same rule, solar panels actually become more efficient the colder it is. This means that for the same amount of light, the solar panels actually produce more power the colder it gets. The beauty of this is that it is almost a balancing act, during summers, the solar PV system is less efficient but gets more sunlight. In winters, it is more efficient, but gets less sunlight.
Solar Systems are very popular in a lot of cold climates around the world, the reason for this is that the savings generated by solar PV systems depend a lot on the electricity rates. The higher the rates, the more savings a solar panel system generates.
An experienced solar PV system designer can design your PV system in a way to minimize power production swings throughout the year. Our solar engineers have designed and installed hundreds of systems and know how to maximize your solar power production during winter months.
