Do Solar Generators Work in Cloudy Weather?
The increasing demand for dependable power can be observed throughout North America, and it is obvious why. From extended blackouts to long weekends spent outdoors in recreational vehicles, it is evident that reliable power has become a necessity. There is also growing concern about the lack of reliable power during outdoor activities. People have become more aware of this fact, especially since we have seen a surge in adverse weather conditions. The increasing number of centralized power grid failures over the last several months has highlighted how sensitive they are to major hurricanes, ice storms, and wildfires. For many families, depending solely on utility companies is not a reliable option for comfort and safety.
For many years, people have used gas generators to provide power. While they created energy, they made some noise, were dangerous to use indoors, and were pricey to refill. This led to the use of solar generators, which, for both outdoor use and emergency home backup, are safer, quieter, and cleaner. Solar technology is a pivotal advancement in the movement away from fossil fuels and the complex logistical tasks of storing gas and exhaust. Keeping gas generators is also a burden because no one wants to deal with exhaust fumes or gasoline.
But one of the essential questions is, what if it’s overcast or cloudy? If there is no sun, do the solar generators just stop working? This is the biggest misconception, and is a reason many people still are not using solar.
To answer the question directly: No, solar generators don’t just stop working on cloudy days. Solar panels do collect energy from the sun; even if it is behind the clouds, it’s just not at full capacity. Being plugged into a Jackery Explorer 2000 Plus Portable Power Station will provide enough power to run the essentials. These types of generators use solar power and, in combination with some backup batteries, give you uninterrupted power, regardless of the changing weather.
1. How Cloudy Conditions are Managed with Solar Generators
Solar panels capture sunlight through the integration of photovoltaic cells. Cloudy weather still allows solar panels to generate electricity, but they generate it at a slower rate. In the case of a cloudy day, solar panels utilize and capture diffuse light instead of direct sunlight, which means they still produce power. Solar Power Systems are never dormant during the day. They continue capturing and converting diffuse sunlight into DC power. Mild cloud cover: Expect 70-80% of peak output.
- Heavy overcast or storms: Output could be as low as 10-25%. Even a modest output allows batteries to be trickle-charged, offsets the power usage of small loads, and thus prolongs the available power from the batteries.
- Winter Months: Even when the sun sets earlier, panels still produce energy. Lower temperatures can increase the efficiency of panels and help improve the situation faced due to the reasonably shorter daylight hours witnessed in the northern locations.
The distinction happens in Power Storage. You can use a Portable Power Station to store energy, which can be used to power devices and appliances like fridges and lights, during sunny days and cloudy days. This strategic storage capability is what decouples the moment of energy generation from the moment of consumption.
Solar generators also use MPPT (Maximum Power Point Tracking) technology to optimize performance, even in cloudy conditions. It is an advanced controller that optimizes voltage and current flows during weak or shifting light, charging, and the solar system being cloudy or slow. The MPPT controller is constantly seeking the maximum power point on the panel’s voltage-current curve to guarantee that there is optimal harvest even in sub-optimal inputs.

3. How It Performs in Cloudy Weather
Explorer 2000 Plus has excellent performance in less-than-ideal conditions. It works this way:
- High-Efficiency MPPT Controller: The system’s MPPT controller takes charge of capturing the sun’s rays, when it is weak and scattered, and converting them into usable power.
Thanks to these constant, micro-level adjustments, very little solar input is wasted, ensuring efficient battery charging.
- Queryable Storage: The base 2,042 Wh capacity can be extended to 12 kWh and, with side-by-side units, to 24 kWh. That’s enough energy to sustain you for several days, even when cloud cover persists. This reserve capacity ensures reliable backup power, ready for unpredictable cloudy days.
- Ultra-Efficient Solar Charging: When the sun is out, the battery can go from empty to full in 2 hours if you use 6 SolarSaga 200W panels. This allows the device to store power for the impending cloudy days. This ability to charge with such speed is vital for regions where sunny days are punctuated by extended periods of cloudy days.
- Integrated UPS System: The moment there is a power disruption due to the storm, the Explorer can automatically switch in 20ms. This means there will be no interruption to the Wi-Fi, computer, and medical devices, which remain powered. This Uninterrupted Power Supply feature means sensitive electronics continue operating without disruption.
- Minimal Noise For Indoor Usage: The silence and lack of emissions from the device allow you to keep it indoors, unlike a fuel-powered generator.
Having the unit inside the home is an operational benefit too, as the unit is sheltered from the weather that usually comes with a blackout.
All this means performance during an overcast day is not as much of a concern. Instead of asking, “Will it work?” the more relevant question is, “How much backup do I need?” This shift in thinking shows the system is a proactive energy manager.

6. Effective Practices in Cloudy Weather
The following techniques will help you get the most out of gloomy days:
- Focus on the most critical loads first. These will include things like a refrigerator and medical devices. If cloudy weather persists, consider stopping the charging of devices that are not critical, which will help you conserve the little energy that is produced.
- Aim the panels into the sky with no shading. The panels should be placed in the most scattered sunlight zones. There is more energy harvested even with very thick cloud cover, and it’s important to minimize the localized shadow that’s cast by nearby trees and buildings.
- Battery longevity comes with avoiding deep discharges and discharging frequently. The rule of thumb with LiFePO4 is that it is tolerant of partial states of charge; you don’t have to deplete in order to start.
- In order to achieve the greatest efficiency, panels have to be clear of dirt and snow buildup.
This is not an exhaustive list, but it is a good list of what season or weather conditions should help you get ready.
