Over the past decade, solar panels have been a huge hit globally. The number of solar panels will surpass 3,000,000 by 2021.
While solar systems aren’t new technology, many people still have questions. You can take a deep dive, especially in hot climates. Solar panel output decreases if temperatures rise above 77 degrees Fahrenheit (25 Celsius).
Solar panels are more effective in certain areas than others. For example, in Las Vegas, the sun is hotter and solar panels produce more power than in San Francisco. SF’s cooler climate keeps the device at the optimal temperature for energy output when there is the sun.
It might surprise you to learn that solar systems are very popular in gray areas, like Seattle, the place with the most cloudy days. Portland, Oregon, the second-cloudiest city in America is a top-rated US city for solar power. Both cities have long summer days and mild temperatures, which provide ideal conditions for maximum solar output. This helps to offset the lower production during the winter months.
Solar panels work well on cloudy days but less efficiently. Solar panel performance drops when it gets too hot. However, solar panels are still worth the effort in all climates.
Are solar panels able to work at night?
They don’t. Solar panels require sunlight to produce energy, as we have already mentioned. They can also generate energy from street lights or the moon, but the output is limited. Solar panels fall asleep at night due to this. They become inactive and cease producing electricity.
How can solar panels be used to provide power for homes at night?
Solar panels do not produce electricity at night, as we have already mentioned. They do produce more power during daylight hours when the sun is shining. To balance the system and maintain electricity supply after dark hours, customers can use solar batteries to store power or meter.
Solar battery storage
Solar energy storage is a simple concept. Solar systems are designed to produce more electricity than your home uses during the day. The excess power generated during the day can be stored in a solar battery solution like the Tesla Powerwall.
When your solar panels go into sleep mode at night, you can turn on the battery system and use stored energy to power your home. His setup can even operate without the utility, meaning that some houses can run offline.
Net metering is a way to use the grid for storage.
Even if your solar panel system does not have storage, you can still use the excess solar energy at night. How? It’s called net metering. Net metering doesn’t require you to store any energy at home. Instead, excess power generated by solar panels is exported into the utility grid during the day. This power is credited to your account.
You can also use your credits later in the night to offset the cost of the electricity. Net metering allows you to store the economic value that you generate, which can be used to reduce, or even cancel, your electric bill. Solar power is a great deal, thanks to net metering.
Recap: When do solar panels work?
Your solar panel system will perform well on cloudy days, but it will also work better when it is not too hot. Your panel brand will determine how efficient your panels perform under different weather conditions.
