Night Solar Panel: Power Generate At Night

Rising electricity prices have driven increased dependence on electricity as a power source for most consumer devices in Pakistan. As a solution, many people are turning to solar panels, which create power through photovoltaic technology powered by sunlight. However, these panels do not generate electricity during bad weather or at night. The industry is now working on producing flexible panels, also known as night solar panels or moonlight solar panels. By incorporating a thermoelectric generator into a conventional PV panel, the researchers achieved a 50 mW/m2 nighttime energy generation.

How do night solar panels work? 

Stanford University has designed Night Solar Panels, which utilize Photovoltaic technology to generate electricity and store energy when sunlight falls on them. These panels, also known as anti-solar panels, overcome power crises when sunlight is unavailable. They contain semiconductor cells that convert sunlight into electricity, emit heat at night, and transfer it to cooler space. This heat flow causes the panels to produce electricity at night which has a temperature of around 3 kelvin (-270.15°C). Night Solar Panels represent a significant development in solar technology, reducing dependence on electricity and potentially saving up to 100% on electricity bills. By utilizing these panels during the day and night, significant reductions in electricity bills can be achieved.

Price of night solar panels in Pakistan:

According to a study of 2024, the costs of the nighttime solar panels are given below:

• A 100-watt Night Solar energy panel costs: PKR 25,000 to PKR 35,000.
• A 250-watt night solar energy panel costs around PKR 45,000 to PKR 55,000.
• A 500-watt solar energy panel costs: PKR 65,000 to PKR 85,000.

Comparative Analysis: Day VS Night Solar Panels

• Day Solar Panels

Conventional solar panels, also known as day solar panels, are specially manufactured with photovoltaic technology. When sunlight falls on these cells, they change over warm into power. A converter is connected to it which changes over it into usable power. This power is moreover used in homes and workplaces. The more daylight there is, the more power is created. They do not absorb sunlight. That is, the daylight is changed over into power as long as it falls on the panels. For the generation of new power, more light is required. This is not a very costly system. it is a reasonable system for users. Later, batteries are connected to them to get power and the excess energy is put away in it.

 VS

• Night Solar Panels

These are moreover made with photovoltaic technology like routine solar panels. They take light from the sun during the day and change it into power. After that, the excess vitality is put away in the photovoltaic cells. In adverse climate conditions and at night, they give electricity from their inner warmth. They do not require any additional battery for capacity. They are more costly than routine sun-oriented panels. It is not however used for residential purposes. 

Challenges and Limitations Of Night Solar Panels

Night solar panels have some challenges and limitations, which are listed below:

• The amount of energy a night solar panel can generate can be limited because it generates energy from solar energy stored during the day. If there is not much light during the day and the panels do not store much energy, then they will not produce much electricity.
• They cost more than conventional solar panels. In terms of efficiency, they generate less electricity than conventional solar panels. If more electricity is used during the day, it is possible that the required electricity cannot be obtained at night. They also require regular maintenance and may need to be replaced after a certain time.

Despite these challenges and limitations, night solar panels offer sustainable energy and are quite beneficial.

Advantages of Night Solar Panel

• Continuous electricity Production

They generate electricity continuously because they are designed with photovoltaic technology to store excess sunlight. This allows them to provide electricity in bad weather conditions or at night. In other words, they can provide electricity even when there is no sunlight.

• Environmental friendly

Solar panels also reduce carbon emissions, which keeps the environment clean and makes this source of energy more sustainable.

• Savings In Electricity Bills

These systems reduce dependence on conventional electricity by providing 24-hour free electricity and achieve 100% savings in electricity bills. Although the initial cost is high, the long-life performance compensates for the high initial cost.

• Freedom of Electricity

By using it, you have the freedom to use electricity. There is no risk of load shedding, which means that you can use electricity at will. Using night solar panels also saves battery costs. That is, you don’t have to use the battery to store additional electricity. A solar panel always provides electricity by itself.

• Enough Power generation

Night solar panels also increase the overall production of electricity. They work together with other panels and can generate energy quite easily even in low light or darkness, saving a lot of electricity.

Future of Night Solar Panels in Pakistan:

The use of solar panels is increasing day by day in Pakistan as technology improves year by year. People can store the sun with the help of solar panels, even in the dark. Homes and businesses have electricity all the time with the help of solar panels if other power sources are not working. Using better batteries for better results, we can have electricity all the time, even if the sun is out or the weather is dark. As more people and the government invest in the technology, using a solar panel system becomes very easy. If we incorporate this type of technology into our daily lives, we can reduce pollution and become less dependent on coal, oil, and gas.

Conclusion:

Night solar panels are promising for the journey towards 24-hour uninterrupted power supply. They are designed to absorb heat by themselves. Although they are slightly more expensive than traditional solar panels, they can be quite beneficial. In the near future, their use will become common and the prices will also decrease. They are responsible for saving electricity and bills. They are the best solution for a continuous supply of energy.
