Best Solar Panels for Cloudy Days 2020

(Last Updated On: November 7, 2020)

Solar panels are widely used all over the world as an alternative source of energy and offer an affordable and alternative source of power generation. The solar panel consists of photovoltaic (PV) cells that use sunlight as a primary source of energy and generate electricity with the help of sunlight. The collective assembling of PV modules on a panel generates electricity and then supplies it to the batteries attached to the solar panel to store it for use. Solar panel absorbs sunlight directly from the sun as it is placed directly under the sun and generates power with the help of the photovoltaic effect. We have compiled some of the best solar panels for cloudy days in the article. We suggest you have a look at them.

Most of the solar panels either use wafer crystalline silicon cell or thin-film cells that help the panel to convert solar power into energy and then transmit the energy for storage. However, you need to protect the cells from damage or moisture to keep the panels working a long time. The solar panel systems carry a junction box at the back of the panel that works as an output interface making the panel weatherproof and useable for a longer period.

Since solar panels take sunlight as a primary source of energy to convert the same into electricity, so sunlight is a vital factor for effective power generation. However, traditional solar panels don’t work if there is insufficient sunlight and ultimately takes less energy that would result in low power generation.

Fortunately, we are blessed with modern technology lately that has allowed the generation of power even in the cloudy weather conditions. Researchers have developed black silicon solar cells that are capable of absorbing more light and produce more energy than conventional solar panels. Most of the modern solar panels equip this technology for yielding higher benefits for electricity generation.

There are different types of solar panels available on the market, you need to know how each type works, its capacity of power generation and price to buy a one for yourself. There are three broad categories of solar panels which are discussed below:-

Monocrystalline Solar Panels

This is the most efficient type of solar panel; its efficiency rate is 20% and best for commercial use. Although it is an expensive type of solar panel that is used commercially. They give maximum performance no matter how the outdoor conditions are.

Polycrystalline Solar Panels

Polycrystalline solar panels offer an efficiency rate of 15% and relatively cheaper than other types of solar panels. The solar panel is sensitive to high temperatures and has a lower lifespan with a huge requirement of space.

Thin-Film Amorphous Silicon Solar Panel

This is another commonly used type of solar panel that comes at a low cost and offers an efficiency of about 10%. However, it has a shorter warranties and lifespan.

We have researched some of the best solar panels that work on cloudy days and great for personal and commercial use. We have described each solar panel in detail helping users to decide easily to pick the solar panel for their use. Check out the best solar panels for cloudy days as below:-
