Solar panels can be a great long-term investment, are they good all year round? Do seasonal changes have an impact their efficiency? What happens in the colder, cloudier months? Will you be paying more in one season than the other?
You’ve already made such a huge investment getting solar panels so the last thing you want to face are unexpected expenses from something that’s designed to save you money.
What Factors Affect Solar Panel Efficiency?
Solar panels are rated to work in a certain set of conditions, but the amount of energy they can be expected to produce changes with each of the seasons. The physical location of your solar panels may also receive more or less sunlight as the position of the sun and shadows change throughout the year. It’s important to take seasonal changes into account when determining the placement of your solar panels. Stormy or cloudy weather can also reduce the amount of energy your panels collect, as can searing temperatures.
Seasonal factors that can impact solar energy production include the following:
The Time of Day
Peak solar times vary throughout the day over the course of the year, with winter leading to higher energy production in the morning and less in the afternoon. This can impact how much you pay for energy, as you may have to draw from the grid during different times of day than in the summer.
The position of the sun will change throughout the year, with the solstice marking the point where the sun emits light with increasing or decreasing intensity for several months. A building and different parts of a roof can get more or less sunlight or shade throughout the year. To maximize your solar panels’ output, it’s important to avoid any shadows that can occur throughout the day across the seasons due to the changing position of the sun.
Much of Las Vegas’ cloudy weather occurs in the fall and winter, which already have less intense sunlight than the spring and summer. While your solar panels will continue to produce during these times, they’ll make less energy and you might have to draw from the power grid. High winds are common in the spring and summer and can blow dust or debris onto your solar panels, which may require cleaning to maintain optimal production.
High temperatures during the peak solar production months can actually reduce the amount of energy that your solar panels are able to produce. Even though the sunlight is less intense in the fall, your panels can still produce a large amount of energy thanks to less stress being out on their systems. However, the loss in efficiency due to high temperatures usually hits a maximum of around 15 percent in Las Vegas.
Will I Pay More for Electricity in Winter With Solar Panels?
While your solar panels will likely produce less energy in the winter months, this doesn’t necessarily mean you’ll have to pay more. People often use less energy in Las Vegas in the winter, which can counterbalance your solar panels’ lower overall energy generation. Solar solutions can produce energy throughout the year and, despite seasonal variations, can help you save on overall energy expenses.
