Price of Night Solar Panels in Pakistan

ByHina Gul

Are you tired of high electricity bills and frequent power outages in Pakistan? Imagine that you can access affordable and reliable energy even at night. The night solar panels save solar energy during the day and use this energy to generate electricity at night time. If you are interested in exploring nighttime solar panels with energy storage in Pakistan, you are at the right place. 

Solar panels generally serve the purpose of producing electricity during the day time only but night time solar panels save this energy and utilize this to produce electricity at night. The sunlight generated during day time is saved in batteries. This saved energy is then converted into electricity at night time when you can not get direct solar energy. On an average, the price of Night solar panels in Pakistan in 2024 ranges between PKR 35000 to PKR 85000.

What are Night Solar Panels?

Night solar panels are nothing but utilization of saved solar energy at the night time. The power outages in Pakistan and rising electricity tariffs have become a grave concern. Recently, a lot of industrial and residentials users have started to shift to alternate energy solutions like solar energy. 

The electricity needed during the day is quite sorted. For electricity required at the night time, Night Solar Panels are the best solution. They are an added technology to regular solar panels with batteries that save solar energy received during the day and utilize the same solar energy to produce electricity at the night time.

How do Night Solar Panels work?

Night solar panels, also known as “Anti-solar panels” or “Thermo-radiative cells,” work on a different principle compared to traditional solar panels. The Night solar panels generate electricity by radiating heat. At night, the Earth emits infrared radiation as it cools down after absorbing solar energy during the day. The night solar panels use the temperature difference between the warm Earth and the cooler night sky to generate electricity.

Mechanism behind Night Solar Panels

  • Thermo-radiative Effect: Night solar panels utilize the thermal radiative effect. This is the reverse of the photovoltaic effect. Instead of absorbing photons and generating electricity, these panels emit photons (infrared radiation) and generate electricity.
  • Temperature Difference: The key to generating electricity at night lies in the temperature difference between the panel and the night sky. The panel, being warmer than the cold night sky, radiates heat. This radiation can be converted into electrical energy.
  • Semiconductor Materials: These panels are made from semiconductor materials that are sensitive to infrared radiation. When the panel emits infrared radiation, electrons in the semiconductor move, creating an electric current.

Benefits of Night solar panels

  1. Saves Significant electricity bills

With Night solar panels, there is no more reliance on Mains electricity, hence, having a significant impact on electricity bills. Residential electricity consumers are more likely to get relief with the help of night solar panels.

  1. Uninterrupted Power Supply

Pakistan has been witnessing a lot of load shedding over the past few years. There is a significant shift towards alternative energy sources like solar panels, that guarantees a continuous power supply. No further relying upon electricity generating companies any more.

  1. Stable Energy Resource

Investing in Solar panels is a one time cost. This provides long term savings on basic utilities like electricity further enabling households, businesses and factories to have stable electricity.

  1. Reduced Environmental Pollution

Traditional electricity generation requires combustion of gas adding dangerously extreme to environmental pollution. Shifting towards solar panels contributes to reduction in pollution as well.

Future of night solar panels in Pakistan

If we talk about Pakistan, the future of solar panels along with night time solar panels is bright. With the advancement in technology and people getting an increased awareness about technology, there is a significant shift to solar panels installation witnessed. Furthermore, the energy crisis and increase in electricity tariffs has added fuel to this fire. Pakistan is even witnessing a shortage of solar panels due to a steep incline in the demand of solar panels, inverters and batteries. This demand is expected to grow exponentially in the upcoming years.

Availability of night solar panels

The concept of Night Solar Panels is currently being researched in Pakistan. An Alternative of night solar panels is a traditional solar panel integrated with a battery to provide stored energy during the night time. A fully flourished concept of night solar panels, that works on the principle of thermal radiative effect (opposite of photovoltaic effect in day solar panels) is not currently functional in Pakistan.

FAQ’s

Conceptually, solar panels are configured to work during the day time till the sun is out. However, night solar panels are also gaining popularity who tend to utilise energy at night time. These include

  • Thermal solar panels that store heat from the daylight into the solar panel using a fluid known as Molten Salt. 
  • PhotoVoltaic Batteries store sunlight they receive during the day and use this to produce electricity at night.
  • Lunar Power: An emerging concept that is working on using lunar energy for power generation at the night time.

Solar panels work entirely on producing electricity from the energy received from sunlight. However, on cloudier days, the solar panels still function, though, at a reduced efficiency level.

Traditional solar panels cannot be used at night because they rely on sunlight to generate electricity. Solar panels are made up of photovoltaic (PV) cells, which convert sunlight into electrical energy through the photovoltaic effect. At night, there is no sunlight to be absorbed, and therefore, no electricity can be generated.

While solar panels do not produce electricity at night, energy storage solutions like batteries can store excess energy generated during the day for use at night.

Solar panels that work best in low light conditions are typically made from materials that have high efficiency and good performance in diffuse light. Here are some types that are known for their effectiveness in low light:

  • Monocrystalline Solar Panels: These panels are made from a single crystal structure and are known for their high efficiency and performance in various light conditions, including low light.
  • Polycrystalline Solar Panels: While generally less efficient than monocrystalline panels, they still perform reasonably well in low light conditions.
  • Thin-Film Solar Panels: Particularly cadmium telluride (CdTe) and copper indium gallium selenide (CIGS) thin-film panels can perform well in low light due to their ability to absorb a broader spectrum of light.
  • Bifacial Solar Panels: These panels can capture light from both the front and back sides, which can be beneficial in low light or overcast conditions where light may be reflected from the ground or surrounding surfaces.

Conclusion

Night Solar panels are a new concept in the field of alternative energy solutions. With significant increase in power tariffs, excessive load shedding, there are a lot of consumers shifting towards solar panels that provide stable and cost effective and equally beneficial alternatives to traditional electricity. The prices of solar panels are expected to increase in the next 6 months.
