Do Changes in the Season and Weather Affect Solar Panel Energy Production?
For an energy system based entirely on natural weather conditions, it seems pointless to ask whether changes in the seasons and weather affect solar panel energy production.
Contrary to popular belief, however, solar panels aren’t the most effective in hot weather. This may sound confusing until you actually gain a better understanding of how these systems work and what their ideal operating conditions are. That’s where our blog comes in.
To find out exactly what we’re talking about and what all of this means for your solar panels, continue reading the post below. We break down why higher temperatures aren’t the best for your solar panel system.
Are solar panels more effective in hot weather?
When it comes to this particular topic, many of our buyers are confused about the distinction between sunny weather and hot weather. There is, however, a crucial difference between the two when it comes to optimised solar panel energy production.
It’s also important to note that while it’s generally sunny when it’s hot, heat can clamp down on the efficiency of your solar panels.
What does this look like in practice? Say, for instance, that you have a 20kW solar panel system. This means that the maximum energy your panels can produce at any given time is 20kW. When it’s hot, your system will peak at a lower maximum power production level because of the heat. Conversely, cooler weather will mean that your system peaks at a higher level, maybe even achieve maximum output.
Why are cooler temperatures better for solar panel energy production?
Now that we’ve established that higher temperatures aren’t the most ideal for solar panel energy production, what makes cold weather more suited for these devices?
What you may not know is that solar panel system components have a negative temperature coefficient. This means that solar panels experience less resistance in cooler temperatures and produce more power.
So, while hotter temperatures certainly won’t prevent your panels from working the way they should, you’re not likely to enjoy maximum energy output. In fact, solar panels work surprisingly well even in snowy conditions. As long as the snow is not completely obstructing your panels, you can guarantee a certain amount of energy production for your home or office.
Just make sure to wipe snow off the surfaces of your panels from time to time. You can also change the angle of your panels by tilting them higher. This generates the maximum amount of energy during daylight – just make sure your panels are facing the south during the colder seasons. If you’re unsure of how to do this, consult skilled and experienced solar panel experts.
How do seasonal changes affect solar panel energy production?
A fact that isn’t much of a surprise to most is that solar panel performance is directly affected by seasonal changes as well.
While summer is often considered one of the best months for energy production, you may be surprised to find that transitionary seasons – spring and early winter, for instance – are the best for solar panel energy production.
While sunlight during spring and early winter may not be as strong as it is in the summer, the attendant external temperature isn’t as high as well – the perfect operating conditions for your solar energy system.
Solar panel energy production is an important aspect of our work, here at Earthsave. Given our goal of ensuring that we meet your energy needs perfectly, understanding this topic in its entirety is important.
This is because choosing the best solar panel system for your home will depend, in part, on the temperature and general climate of the area you live in. Fortunately and contrary to popular belief, these systems perform exceptionally well in colder temperatures too!
