You need to know about solar seasonality to understand your electricity bill. You also should learn how sunlight affects electricity bills. Different weather means varying electricity bills. This article will explain the relationship between solar seasonality and electricity bills.
Solar Seasonality
These variations in solar energy generation are caused by seasonal changes in sunlight and weather distribution. There are different levels of sunlight, just as there are different temperatures for every season.
The Sun And Solar Panels
Solar panels make the most electricity in peak sunlight hours when direct sunlight falls on these panels. There is a reduced output of electricity other than peak hours since energy production is directly related to:
- Sunlight angle.
- The sun’s radiation.
- The expected position of the sun throughout the year.
- The sun’s brightness.
This variability affects the energy that is created by your solar power system. Elaborating further on angles, it’s not just the sun’s angles that matter but also the angle of the solar panel which affects solar panel efficiency. This is calculated by factors like:
- The direction of your roof.
- The angle of your roof.
- Historic precipitation levels.
- Average cloud cover.
- Average daylight hours.
Solar installers employ sun databases based on historical data to design solar panel systems. These databases help them determine the expected solar irradiation levels for different geographic regions and change them according to your system.
Electricity Consumption
Varying seasons have different electricity production and different electricity consumption. It is common to run the air conditioning frequently in hotter months; during colder months, a heater may be used often. This means that electricity consumption will also fluctuate throughout the year.
Net metering can be a great help, especially if you live in an area with such a program. For instance, you should survive mild winters without turning on the heater to enjoy those energy savings by running the air conditioning during blistering summers.
Seasonal Solar Panel Performance And Utility Bills
Since seasonality directly affects solar panel performance and solar performance affects utility bills, the duration of sunlight received by the solar panels and the sun’s angle can significantly influence how much money you’ll save. In winter, sunlight duration is typically less than in summer, so electricity output is low.
As this low output won’t meet your energy needs, you’ll have to resort to the grid, which will cost you money. Even if solar panels meet your energy needs, this doesn’t mean there will be no electricity bills. Your home will sometimes need power from the electricity grid instead of your solar panels. By being aware of this pattern, you can predict fluctuations in your energy bills.
Weather Conditions And Efficiency
Anything that blocks the sunlight from reaching your solar panels will affect the production of solar energy. This can be shade from any object, clouds, rain, or any other weather condition. Let’s explore the different weather conditions and how they affect solar energy production:
Snow:
Solar panels can generate electricity even if a thin layer of snow covers them. It is better to clean the snow on your solar panels, but a thin layer will typically melt itself due to sunlight and heat. However, a thick blanket of snow seriously affects your solar power production. This is why keeping the panels at an angle that can assist in keeping the snow off the panels is helpful.
Rain:
Solar panels can function on cloudy days, but they won’t be generating electricity at peak efficiency due to limited sunlight.
Cold Climates:
You can still produce electricity in cold places. Modern solar panels are designed to operate in the temperature range of 45°-75°F as long as they are exposed to sunlight.
Hot Climates:
It is common to think that the amount of sunshine is directly proportional to electricity generation by solar panels. However, there are other things to consider too. High temperatures (above 80°F) can negatively affect the performance of electronic devices. Increasing temperatures can decrease voltage and efficiency, which ultimately reduces performance.
Is Solar Seasonality Worth It?
Solar panels are worth it since they return the money invested into them in a short period. However, you should consider the effects of seasons on your electricity bills and solar panel performance. The bill will fluctuate due to the amount of sunlight your solar panels receive. By carefully analysing how different seasons and weather patterns affect your electricity bills, you can effectively predict how to save money in the most efficient way possible.
