DO SOLAR PANELS WORK IN COLD WEATHER?

WHAT'S THE SCIENCE BETWEEN SOLAR PANELS AND TEMPERATURE?

Even in below-freezing weather, solar panels turn sunlight into electricity. That’s because solar panels absorb energy from our sun’s abundant light, not the sun’s heat. In fact, cold climates are actually optimal for solar panel efficiency. So long as sunlight is hitting a solar panel, it will generate electricity. Any diminished output during the winter months will primarily be due to heavy snow and shorter daylight hours.

So, how do solar panels work? When sunlight photon particles hit solar panel photovoltaic cells, electrons in the silicon are put into motion. This creates an electric current, which is sent to your home’s electric distribution box to power your essential items. A rechargeable solar battery can help store this electricity so you can still use solar energy at night, during peak electricity usage, or when the grid goes down.

Remember how electrons move around atoms? Electrons are at low energy in cooler temperatures. When these electrons are activated by increasing sunlight (high energy), a greater difference in voltage is attained by a solar panel, which creates more energy. That’s why solar cells produce electricity more efficiently when it’s colder.

when it’s cold ,it is also less likely for solar panels to reach their peak temperature, or peak power. Once their temperature rises above that peak temperature, solar panel performance decreases.

Research has demonstrated that panels begin losing efficiency around 77ºF.However, this diminished efficiency is balanced out thanks to more daylight hours during the spring and summer months.

Do solar panels work when it rains?

The sun still delivers daylight to solar panels through the rain and clouds. Although solar panels are most productive in direct sunlight, they can still use diffuse or indirect sunlight to generate energy. Rainy days and clouds cause diffuse light. But what’s the difference? 

Direct light is solar radiation traveling in a straight line from the sun down to the earth’s surface. Diffuse light is sunlight that has been scattered by particles in the atmosphere yet still reaches the earth. Thus, the amount of electricity generated is dependent on the density of cloud cover. Though energy production decreases with increasingly dense cloud cover, panels continue working to a greater capacity than one may expect. Rain also helps wash away dust on panels to keep them operating efficiently.

Installing a grid-connected, rooftop solar panel system with battery storage can give you clean, renewable back-up electricity so you can power through the next blackout. We’ve seen that solar panels are incredibly resilient in the face of extreme weather conditions. By pairing your panels with a solar battery, you can store up your sunny days for a stormy one.

It's time time to go solar , While solar panels and battery storage can be a significant investment, Pontus Technology Limited offers stress-free and reliable Solar services.

  ADVANTAGES OF USING CCTV SYSTEMS FOR YOUR BUSSINESS CCTV can provide a whole host of advantages within the building in which it is installed, along with its contents and any workers or residents.     Benefits of CCTV Cameras in Business  Here, we run through some of the top benefits that this safety system can bring to businesses of all types, and why it is a great thing to have installed at your business premises. 1. Crime deterrent It goes without saying that having a CCTV camera installed at your premises will act as a serious deterrent to criminals and anyone carrying out illegal activities. The sight of a CCTV camera infers an air of danger and the presence of the law, deterring anyone planning to carry out a crime from doing so. 2. Monitors activities CCTV systems are able to keep track of what is happening at the premises where they are installed. By monitoring the activity of workers and visitors at your business’ site, you and your workfo...

POWERING A SAFER FUTURE WITH RENEWABLE ENERGY Energy is at the heart of the climate challenge and key to the solution. A large chunk of the greenhouse gases that blanket the Earth and trap the sun’s heat are generated through energy production, by burning fossil fuels to generate electricity and heat. Fossil fuels, such as coal, oil and gas, are by far the largest contributor to global climate change, accounting for over 75 percent of global greenhouse gas emissions and nearly 90 percent of all carbon dioxide emissions. The science is clear: to avoid the worst impacts of climate change, emissions need to be reduced by almost half by 2030 and reach net-zero by 2050.To achieve this, we need to end our reliance on fossil fuels and invest in alternative sources of energy that are clean, accessible, affordable, sustainable, and reliable. Renewable energy sources which are available in abundance all around us, provided by the sun, wind, water, waste, and heat from the Earth – are reple...

  HOW TO CHOSE THE RIGHT INVERTER AND BATTERY FOR YOUR HOME  Are you planning to buy a new inverter or upgrade your old one? Whatever maybe the reason, it is very important to understand what is the right inverter for your home. The power requirement at your home can be different from you neighbor’s home. So do not just blindly install the same inverter (in terms of power) in your home. Before buying an inverter for your home do a little homework and understand the basics. First understand your Power Requirement  One of the most important factor that you must know before buying an inverter is your “Power requirement”. In simple words, what all electrical appliances like fan, tube lights, television, etc, you want to run at the time of power failure. The power requirement is addition of the power consumed by various electrical equipment. Suppose you want 3 Fans, 3 Tube lights, 1 fluorescent and    1 television to operate at the time of power failure....
