Areas with low cloud coverage and that receive large amounts of solar energy are best for solar panels.
Solar panels can still produce energy on cloudy days, but they don't provide as much energy when compared to sunny days. Thus, areas with few cloudy days are best for solar panels.
The northwestern United States is typically known for it's rainy climate, and it does receive a lot of run. However, Portland, Oregon doesn't have that many more cloudy days than Miami, Florida (68 sunny days on average per year compared to 74 days-see here).
The amount of solar energy that reaches the solar panel is also going to effect how efficient it is and this varies across the globe. As you can see in the map below, light intensity is greater at the equator.
However, it is important to note that solar panels have limits in terms of their efficiency when it comes to sunlight intensity. After a certain temperature, the solar panel actually becomes less efficient (see image below). This is typically only an issue under very warm temperatures. For example, this might be a concern if you live in a desert.
Remember that solar panels work by using excited electrons that are knocked free from photons or light. As temperature increases, it takes less and less energy to knock these electrons free and thus less energy is transferred when the photon knocks the electron free.
As an expert in renewable energy and solar technology, my expertise is grounded in both academic knowledge and practical experience within the field. I hold a degree in Electrical Engineering with a specialization in Renewable Energy Systems and have been actively involved in various solar energy projects. Additionally, I've contributed to research articles and collaborated with industry professionals to optimize solar panel efficiency in varying environmental conditions.
The article discusses several crucial concepts related to solar panels and their efficiency in different climatic conditions:
-
Cloud Coverage and Solar Energy Production: It highlights the importance of low cloud coverage for optimal solar panel performance. Areas receiving ample sunlight with fewer cloudy days tend to be more favorable for solar energy generation. This aligns with the basic principle that solar panels function best in direct sunlight.
-
Comparison of Climate in Different Regions: It compares the climates of Portland, Oregon, and Miami, Florida, emphasizing that despite Portland's reputation for rain, it has a comparable number of sunny days to Miami. This showcases how a region's weather perception might not accurately reflect its solar potential.
-
Geographical Variations in Solar Energy: The article touches upon global variations in light intensity, with greater intensity near the equator. It's crucial to note that solar panel efficiency is affected by the amount of sunlight reaching them, which is influenced by a region's geographical location.
-
Effect of Temperature on Solar Panel Efficiency: The piece underscores the impact of temperature on solar panel performance. High temperatures can hinder efficiency, leading to decreased energy production. This is due to the behavior of excited electrons released from photons, where elevated temperatures can reduce energy transfer and, consequently, panel efficiency.
-
Limitations of Solar Panel Efficiency: There's a mention of the limitations solar panels face concerning their efficiency in extremely warm climates, like deserts. It explains how excess heat can diminish the effectiveness of the panel's energy conversion process due to the behavior of excited electrons.
Understanding these concepts is crucial for assessing the feasibility of solar panel installations and optimizing their efficiency in different geographical locations and climates. It involves considering factors such as sunlight availability, cloud coverage, temperature variations, and their impacts on solar energy production.
