Does Solar Work In Winter?
Does Solar Work in the Winter?
Transition to solar is a thoughtful process that considers the entire annual production cycle. Despite a common misconceptions about the effectiveness of solar panels in winter, rest assured that solar systems are carefully designed to provide sufficient energy year round.
Solar systems are designed to maximize production throughout summer. They take advantage of extended daylight hours and heightened sunlight to accumulate unused energy. This energy is stored for use during winter, when limited sunlight hours, snow, and cloud cover may reduce production.
While winter may present challenges, the solar system’s capability to build up excess energy during more favorable periods ensures a dependable energy supply throughout the year. This year-round approach to energy generation offers homeowners a continuous, reliable power source despite seasonal variations or weather conditions.
Now, let’s dispel the common misconception regarding solar panels’ effectiveness in winter.
The good news is that not only do solar panels continue to function during winter, but they exhibit increased efficiency. While unique winter conditions—such as reduced sunlight hours, snow, and cloud cover—may lead to a temporary dip in system production, it’s crucial to recognize that solar systems are carefully designed to guarantee uninterrupted power throughout the entire year.
Solar Performance During Winter
Homeowners may be surprised to hear that solar panels actually function more efficiently during the winter than the summer. Panels are powered by sunlight, not heat, so like most electronics they actually work better when cold than when hot. This means that your solar panels will produce more energy per sunlight hour in the winter than in the summer.
While this means that your solar system is performing at peak efficiency during the winter, the limited sunlight hours each day during the winter do still cause your system to produce less energy than in the summer. The energy your system produces in the winter will probably be less than the amount of energy your home needs.
Solar Energy Storage: Saving Up for Winter
The limited sunlight hours during the day and your home’s increased energy usage in winter months may leave a gap between your system’s production and your home’s consumption. That’s why we design your system to prepare for the winter months ahead of time.
We build your solar system to produce more energy during the high production summer months than your home needs. All of this excess energy that your home does not use during the summer will be stored up for you to use during the winter, when your system is not producing as much. You can store this energy on the grid using net metering, or you can add a solar battery to your system as a backup power bank.
Your home will automatically pull the energy it needs off of your solar battery or the power grid whenever your solar system is not producing enough for your home. You see this on a smaller scale every day: your solar panels don’t produce energy at night when the sun is not out, so we build your system to overproduce during the day so you can store up extra energy to use at night.
Using the Power Grid for Additional Energy
What if you don’t have enough energy stored to cover your home’s energy usage?
Well, all solar systems are connected to the grid, even systems that use battery storage. That means if you ever run into an instance where you need more energy than you have stored, you will be able to pull extra energy from the grid. Your utility company will keep track of how much extra energy you take and bill you accordingly.
There are a variety of reasons you could end up in this situation. Maybe a recent home upgrade increased your energy consumption: a hot tub, pool pump, or electric vehicle, for instance. Maybe you just experienced a record cold winter and have been using the heater more than usual. Whatever the reason, you always have backup options to ensure you get the power you need.
Power Through the Winter Months with Solar
These backup options ensure that your solar energy system continues to provide the power you need year round. While you may notice variations in your system’s production and your home’s consumption each month, over the course of the year these fluctuations will balance out and your system will provide you with the energy promised. If not, we will reevaluate your system, making any changes or upgrades necessary to provide the energy you were promised!
Don’t let the winter chill stop you from going solar. When we build your system, we make sure that you will always have access to the energy your home needs. You can expect to keep enjoying the many benefits solar has for you and your home year round.
