They use the available light during rainy and cloudy days. They don't operate at their full potential during these days, but they do still work. Just as we can still see during rain or clouds, so can a solar panel. It just doesn't produce as much output because it is getting reduced sunlight.
WHEN it works - solar by day, wind when its blowing.
Compared to base load electricity sources like coal-fired power stations or nuclear generators, solar energy is not reliable because it need the sun shining on the panels The sun goes out at night, and is sometimes covered with clouds during the day. The capacity factor of a solar installation may be as low as 25%.
One problem associated with the use of solar energy the cost to purchase the solar panels and convert the energy. Another problem is there needs to be a way to store the energy when the sun is not out.
A plant is likely to produce more oxygen on a cloudy day than on a rainy day. On cloudy days, photosynthesis can still occur, albeit at a reduced rate due to less sunlight, allowing for some oxygen production. In contrast, during rainy days, water saturation can limit gas exchange and potentially reduce photosynthesis, as waterlogged soil may hinder root function and oxygen availability for the plant. Thus, while both conditions can affect oxygen production, cloudy days generally provide a more favorable environment than rainy days.
a crime lab works during the day and the night !!!!!!!!!!!!!!!! a crime lab works during the day and the night !!!!!!!!!!!!!!!! a crime lab works during the day and the night !!!!!!!!!!!!!!!!
No more working well under a cloudy rainy season. It could down to 30% compare to bright sunny day.

Solar panels will still generate some electricity on a cloudy day, although the output will be lower compared to a sunny day. The efficiency of the solar panels will decrease as there is less sunlight available for conversion to electricity.
are affected by cloud coverage and day length"
This depends entirely on the efficiency and size of the solar panels, and the lighting conditions.
Solar panels would not generate electricity if there is no sunlight available. They rely on sunlight to produce electricity through the photovoltaic effect. In the absence of sunlight, the panels would not be able to convert solar energy into electrical energy.
You can put solar panels on your roof to generate electricity from the sun. This can be stored in batteries or fed back into the grid.
Solar panels are not a renewable resource, unless you recycle them. Solar panels make electrical power from solar energy, but it in no way replenishes the Sun to make more solar energy in the future. However, the Sun does rise every day, and when it's not cloudy the electrical energy produced by the panels is reinstated.
Battery back up.
The cost of it and places that don't get much sunlight in the winter can't make as much electricity. From: Coolgirl1869 Solar power is great overall, but some disadvantages are that solar panels, installation, and repairs are VERY expensive. Also, the weather can effect the efficiency of the solar panels. Solar panels can only process energy throughout the day, even though it usually has enough power saved up to run everything all through the night, which is another disadvantage. And pollution levels can also effect the solar panels efficiency.
There are many variables which will affect the answer, how big the panels are, how many you have and in what sort of climate they are.
Solar panels require about 5 to 6 hours of direct sunlight per day for optimal performance.
