It likely goes without saying, but of all the energy solar panels generated last year, none of it was produced at night. New research is showing that doesn't have to be the case. Researchers at Stanford modified commercially available solar panels to generate a small amount of electricity at night by exploiting a process known as radiative cooling, which relies on, no lie, the frigid vacuum of space. When an object is facing the sky at night, it radiates heat out to outer space, which means that an object can become cooler than the air temperature around it. This effect could have obvious applications in cooling buildings, but the difference in temperature can also be used to generate electricity. While the modified panels generate a tiny amount of energy compared with what a modern solar panel does during the day, that energy could still be useful, especially at night when energy demand is much lower, the researchers said.

One day, there will be no more fossil fuels. We do not have a say in this. They simply will be gone, consumed, transformed from potential energy into kinetic and off to the next thing they will be.
Instead, we will be sunflowers, traveling with the light.
Instead, we will be sailboats, traveling with the wind.
Instead, we will be Hephaestus' hearth, warmed by the molten rock below.
One day soon we will live an alternative energy reality and it is up to us to prepare.
I'm living in a flat without balcony on the second floor. I'm not allowed to modify the building stock, like drilling holes into exterior walls. Nonetheless, I want to use solar energy to cover the base load of my flat. Over the last couple months I developed a DIY solution to accomplish just that. A solar panel is clamped into a window embrasure with a telescopic rod. The power is carried through the window into my flat with a special flat conductor.
This is a work in progress, so please visit the project documentation at https://hackaday.io/project/192011-window-mount-for-solar-panels if you are interested.

As the Earth tilts and turns, the changing seasons can have a profound effect on the performance of solar power systems. From the height of summer to the depths of winter, a solar panel owner’s strategy must adapt to ensure their system is optimized throughout the year. Let's take a closer look into how each season affects solar output and how you can maximize your system's efficiency, regardless of the weather.
Summer: Sun’s Out, Panels Out
Summer often means longer days and more direct sunlight, which is excellent news for solar energy production. In the United States, the average solar panel efficiency can climb during these months due to increased insolation – a term that refers to the amount of solar radiation reaching a given area. The Solar Energy Industries Association (SEIA) reports that in peak summer, a well-positioned solar panel system can produce twice as much energy as during winter. However, extreme heat can sometimes decrease panel efficiency, a phenomenon known as temperature coefficient, typically resulting in a performance drop of about 0.5% for every 1°C above 25°C.
Fall: Preparing for the Pivot
As fall approaches, the sun’s angle begins to lower, and days get shorter, which can lead to a decrease in solar production. Despite this, cooler temperatures can enhance panel efficiency, slightly offsetting the loss from reduced daylight. It’s essential to prepare for leaf fall during this season, as debris can obstruct panels and impact performance. A National Renewable Energy Laboratory (NREL) study suggests that a single leaf on a panel can reduce power output by up to 10%.
Winter: Weathering the Cold
Contrary to what many assume, solar panels don't go dormant in winter. They can still produce significant energy, especially in areas with strong winter sunlight. Snow can even act like a mirror, reflecting light and potentially increasing performance on clear days. The key statistic to watch, however, is daylight hours. For instance, according to the U.S. Energy Information Administration (EIA), regions like the Pacific Northwest see a reduction of about 40% in solar radiation from November through February, affecting potential output.
Spring: A Time for Tune-Ups
Spring is often seen as a time of renewal, and for solar panel systems, it's an ideal period for maintenance to optimize energy capture. As days lengthen, your solar system's production will naturally increase. To fully capitalize on this, ensure your system is free from the winter’s accumulation of dirt and debris. Data from the Department of Energy indicates that a clean solar panel is approximately 21% more efficient than one covered in the season’s grime.
Year-Round Maintenance and Monitoring
Regular maintenance is crucial for keeping your solar power system at peak performance. It’s advisable to check your system's output against benchmarks provided by your installer or local averages. Most modern systems come with apps or monitoring software, enabling you to track energy production in real-time and notice any significant discrepancies that may indicate an issue.
Utilizing Battery Storage
To truly optimize your system year-round, consider integrating battery storage. This allows you to capture excess energy during peak production times and use it when the sun isn’t shining. For example, Tesla’s Powerwall reports that, when used effectively, battery storage can increase the self-consumption of solar power from 30% to upwards of 70%.
Embracing Energy Efficiency
Lastly, optimizing a solar system isn’t just about maximizing production; it’s also about minimizing consumption. Implementing energy efficiency measures within your home can significantly impact how much solar power you need to meet your energy demands. The EPA suggests that for every kilowatt-hour of solar energy used efficiently, a typical system’s return on investment can improve by 5-10%.
By understanding and adapting to the seasonal shifts in solar production, you can ensure your system is not only effective but also contributes to a sustainable future all year round. Whether you’re dealing with the abundance of summer sun or the scarcity of winter light, these strategies will help you stay powered through every season.
