Investing in solar energy can be a significant decision for any homeowner, especially in St. Louis, Missouri. With the right timing, you can maximize your savings, enhance your home's value, and contribute to a greener environment. In this post, we will explore which month or time of year is best for going solar by considering various factors such as weather, energy savings, and installation timelines. We will also highlight the benefits of solar energy throughout the seasons.

Understanding Solar Energy Production in Different Seasons

Solar panels harness energy from sunlight to produce electricity. Understanding how seasonal changes impact solar energy production is crucial for homeowners. In general, solar panels are most effective during sunny months. However, they can still generate electricity on cloudy days, albeit at a reduced capacity.

Summer (June to August): During summer, the long, sunny days in St. Louis provide the optimal conditions for solar energy production. More sunlight means higher energy output. According to the National Renewable Energy Laboratory, solar panels can produce up to 25% more energy in the summer compared to winter months.

Fall (September to November): Fall is an excellent time to invest in solar panels before winter sets in. Energy production remains high in early fall, and homeowners can take advantage of sun exposure as trees shed their leaves. This season also allows for efficient installation as demand tends to decrease.

Winter (December to February): While winter days are shorter and sunlight is less intense, solar panels can still be effective. Snow can reflect sunlight, potentially increasing output. However, if installation occurs during this season, delays can happen due to harsh weather conditions.
Spring (March to May): Spring brings a rejuvenation in solar energy production, with increasing daylight hours. It is a perfect season to install solar panels as the weather warms and clears up. In addition, some homeowners choose to complete their installations in spring to have everything ready by summer.

Factors to Consider Before Going Solar

Energy Savings and Financial Incentives

Making the switch to solar energy can lead to significant energy savings for homeowners in St. Louis. Many utilities offer net metering, allowing homeowners to receive credit for excess energy produced. Additionally, tax incentives often make solar installations more affordable.

For example, as of 2023, the federal solar tax credit allows you to deduct 26% of your solar installation costs from your federal taxes. This incentive is set to decrease in subsequent years, making it more beneficial to install early.

Weather Conditions and Installation Timeline

Weather plays a crucial role in determining the right time to install solar panels. St. Louis experiences varied weather throughout the year, making some seasons more conducive for installation than others. Spring and fall are generally the most favorable seasons because of mild weather, which can expedite the installation process.

Delays in Winter: Intense snowfall or icy conditions during winter can prolong installation timelines. If you plan to have your system up and running by summer, it's prudent to consider an installation in spring.

Choosing Solar Technology

Different solar technologies may also influence timing. For instance, if you opt for a solar battery installation alongside solar panels, the process may take longer. Battery storage is increasingly becoming popular as it allows homeowners to store excess energy for later use, offering a reliable energy source even during outages.

Benefits of Going Solar by Season

Summer: Maximum Production Potential

As mentioned earlier, summer is the peak season for solar energy production. If you install your solar panels during these months, you can quickly start generating energy and saving on your utility bills.

Moreover, many solar companies offer special summer promotions, making this season a favorable time for potential buyers.

Fall: Preparation for Winter

By installing solar panels in the fall, St. Louis homeowners can prepare for winter and harness the tail-end sun's benefits. This proactive approach allows homeowners to maximize energy production before the cold weather hits.

Additionally, considering that many companies experience slower business in fall, you might find better customer service and potentially lower prices.

Winter: Take Advantage of Lower Costs

If you're looking for cost savings, winter can be an advantageous time for installation. Many solar providers may offer discounts during winter due to decreased demand. Additionally, if you choose to install solar panels, you may benefit from a federal tax credit when you file your last tax return for the year.

Spring: Ideal for Planning and Installation

Spring is widely considered one of the best times to invest in solar. The transition from cool to warm weather allows for efficient installation, and there are often financial incentives available. When you install solar panels in spring, you can prepare for summer months, ensuring you’ve maximized your savings for the hottest season.

Installation and Maintenance Tips

Selecting a Reputable Installer

Choose an installer who specializes in solar energy systems and has a solid reputation in the St. Louis area. Check reviews, ask for references, and ensure they are properly licensed and insured.

Scheduling the Installation

Plan your installation well in advance to ensure it aligns with your financial goals and desired timeline. Contact multiple installers to compare quotes and timelines. Having a clear understanding of the timeline will help align with energy production expectations.

Maintaining Your Solar Energy System

Once you've installed your solar panels, be sure to maintain them for optimal performance. Most solar panels require minimal maintenance, but you should regularly inspect them for dirt, debris, or any obstructions.

Final Thoughts: Is There a Best Time to Go Solar?

The best time to go solar largely depends on personal circumstances, energy needs, and potential savings. As a homeowner in St. Louis, consider the factors discussed in this post when deciding when to invest in solar energy.

Whether you choose to go solar in the summertime when energy production is at its peak or spring when conditions are best for installation, the long-term benefits of solar energy can significantly outweigh the initial investment.

Remember to stay informed, explore financial incentives, and choose the right installer to set your solar journey on the right path. By doing so, you'll not only make a wise investment but also contribute positively to the environment.
