Two Ways Weather Can Affect Solar Energy Production

Two Aspects Of Weather That Can Affect Solar Energy Production

Solar installation is increasingly popular in today’s world. Considering the massive amount of energy produced by the sun’s rays on earth, it makes sense to invest in residential solar or even commercial-use panels in the Bay Area. When running the numbers for energy management, there is plenty to be gained and very little to be lost when installing renewable energy sources in a home or business.

However, the effectiveness of a solar panel’s energy production rests on various factors. Some areas of the world aren’t exactly optimized for this form of sustainable solar energy production. Fortunately, those in California are ready to reap the benefits, as the weather in this relatively warm state is perfect for maximum solar gains.

1. A Solar Installation’s Optimal Temperatures

In Northern California, energy generation is much better than in other areas because of the region’s ideal temperature conditions. Contrary to popular belief, solar panels generate better electricity in colder weather with bright and clear skies over scorching days. Cold panels produce more voltage, while hotter days make them less efficient because of their design.

Depending on the panels you have on your solar installation job, these have spec sheets that show you optimal working temperatures and conditions. The manufacturer has likely tested these and listed them down in your manual. A general rule of thumb is that a panel produces less efficiently by one percent for each degree above 77 degrees Fahrenheit. Conversely, each degree below this number makes the energy production one percent more efficient.

However, the overall effectiveness of a panel’s production rests on general weather conditions. Winters are typically much colder but have shorter periods of daylight and without much sun. There will definitely be periods in the year where the sun is shining, and the temperatures are still quite chilly, such as spring and the days leading towards fall. Summer will still produce electricity well enough because of bright sunny days that are less interrupted and much longer.

2. Light Blockages Affect Electricity Production

Cloudy weather will definitely affect energy production, as residential solar still requires an abundance of sunlight hitting the panel to be effective. Commercial solar can be better because of larger installation surface areas, meaning fewer blockages from trees and other taller buildings. However, a cloudy day that still has some brightness can generate power using your solar installation panels.

While production numbers can drop significantly and affect energy management, some cloudy days have a doubling effect on the electricity produced. Some clouds have edges, magnifying the heat from the sun’s rays and allowing the panels to absorb more.

Overcast days might produce even less, as the generation can be affected by up to 70 percent compared to a sunny day. However, certain areas on the west coast can still benefit from a solar installation, as even cloudy and overcast days can generate a fair amount of energy. You’ll definitely save plenty of money over time with an excellent residential or commercial solar system, so it’s always a good idea to go green with renewable sources of electricity.


Running a solar array is a great way to go green and shift to renewable energy. While the common knowledge is that hot summer days produce the best results, the truth is that solar energy production realizes its maximum potential with cooler temperatures and bright sunlight during the day. As long as there is light, there is electricity for solar power, so invest in a proper system today!
