What is the Difference between Mono Solar Panel and Poly Solar Panel?

Monocrystalline and polycrystalline solar panels are two predominant types of solar technology, each with unique characteristics that affect their efficiency, cost, appearance, and suitable applications.

Composition and Manufacturing Process
Monocrystalline solar panels are composed of a single crystal structure of silicon, which is created by placing a seed crystal in molten silicon to grow a single ingot. This process gives rise to uniform, dark-colored panels that are recognized for their purity and efficiency. On the other hand, polycrystalline solar panels are made from multiple silicon crystals that are melted together and poured into molds, leading to a less uniform appearance characterized by a bluish hue. The manufacturing process for polycrystalline panels is simpler and less expensive, which typically makes them more affordable than their monocrystalline counterparts.

Efficiency Ratings
In terms of efficiency, monocrystalline solar panels generally outperform polycrystalline panels. Monocrystalline panels achieve efficiencies ranging from 20% to over 24%, while polycrystalline panels usually have efficiencies between 18% and 20%. This difference is primarily due to the structure of the solar cells; the single crystal composition of monocrystalline panels allows electrons more freedom to move and generate electricity efficiently.

Performance in Heat
When exposed to high temperatures, monocrystalline panels tend to perform better than polycrystalline panels. They have a lower temperature coefficient, which means their efficiency decreases less drastically as temperature rises. Conversely, polycrystalline panels exhibit a higher temperature coefficient, resulting in a more significant decrease in efficiency in hot conditions.

Cost Considerations
Cost is a crucial factor for many consumers deciding between the two options. Generally, monocrystalline panels come at a higher price due to the complex manufacturing process, with costs typically ranging from $1 to $1.50 per watt before installation. In contrast, polycrystalline panels are priced more affordably, generally around $0.90 to $1 per watt. Despite the initial cost savings with polycrystalline panels, monocrystalline panels may provide better long-term savings through higher efficiency, especially in space-limited installations.

Aesthetic Differences
The visual appeal of solar panels can also influence choice. Monocrystalline panels are usually sleek and all-black, which many find more aesthetically pleasing. Conversely, polycrystalline panels have a blue hue and may appear more variegated due to their composition, which some consumers might not prefer visually.

​In summary, while both monocrystalline and polycrystalline solar panels have their benefits and drawbacks, the choice often hinges on efficiency needs, budget constraints, aesthetic preferences, and roof space considerations.​ Monocrystalline panels are typically favored for their greater efficiency and sleek appearance, making them suitable for residential applications where space is limited. Polycrystalline panels are a more cost-effective option but may require more panels to achieve the same energy output due to their lower efficiency.

The cumulative number of installed households has exceeded 5 million.

Although household photovoltaic installations have grown rapidly in the past two years, overall, the penetration rate of household photovoltaic market is still low. According to data from Sepu Consulting, the penetration rate of household photovoltaics in 2023 is only 8%, which means that there are at least 60 million roofs to be developed. There are still many people who do not know enough about rooftop photovoltaics or have misunderstandings. Today, let’s talk about household photovoltaics.

1. What is household photovoltaics?
Household photovoltaic is a type of distributed photovoltaic, that is, by installing solar photovoltaic panels on the roof or courtyard of the house, solar energy is converted into electricity for household use, and the excess electricity is sold to the grid (self-generation and self-use, surplus electricity is connected to the grid), or the generated electricity is directly sold to the grid in full to obtain electricity fee income (full access to the grid).

2. What are the benefits of household photovoltaic?
Economic benefits: By installing household photovoltaic systems, families can use solar energy to generate electricity, reduce dependence on grid electricity, and thus reduce electricity bills. Excess electricity can also be sold to the grid for additional income.

Environmental protection and energy saving: Photovoltaic power generation is a clean energy that does not produce pollutants such as carbon dioxide. It helps to reduce carbon footprint, protect the earth’s home, do a little to slow down global warming, and leave a safer and more livable home for future generations.

Increase the utilization rate of roofs/courtyards: Roofs and courtyards usually have large vacant areas. Installing photovoltaic panels can make full use of these spaces, and increase the value per unit area without affecting normal use, that is, increase the utilization rate.

Energy independence: Photovoltaic systems enable families to achieve energy independence to a certain extent, especially in areas with unstable power supply or high electricity prices. Improving the safety and stability of electricity is of great significance to improving people’s lives.

Beautiful: Modern photovoltaic panels are beautifully designed and can be perfectly integrated with the roof to enhance the appearance of the house.

3. Precautions for installing household photovoltaics
Before deciding to install a household photovoltaic system, you need to pay attention to the following aspects:

Roof conditions: Make sure the roof structure is stable, has enough space and a good orientation, and is not blocked by trees or other buildings.

System design: According to the family’s electricity demand and roof conditions, choose the appropriate photovoltaic module array and inverter to ensure the best performance of the system.

Policy support: Understand the local power grid’s open capacity, grid connection requirements and power companies’ photovoltaic grid-connected electricity prices, etc. These policies may affect the return on investment and the benefits obtained.

Professional installation: Choose a qualified and experienced installation company to ensure the quality and safety of the system installation and avoid later maintenance and safety hazards.

4. Answers to common problems
Many families may encounter some problems during the installation and use of photovoltaic systems. The following are common problems and their answers:

1）How long is the life of a photovoltaic system?
Generally speaking, the service life of a photovoltaic panel is about 25 years, while the life of an inverter is 10 to 25 years. Regular maintenance and care can extend the service life of the system.

2）Can the photovoltaic system still generate electricity on cloudy or rainy days?
Although the power generation efficiency of the photovoltaic system will decrease on cloudy or rainy days, it can still generate a certain amount of electricity. Therefore, this situation is usually taken into account when designing the system to ensure the stability of power supply throughout the year.

In addition, some new solar cell technologies can even generate electricity at night or on rainy days. These technologies generate electricity by storing the energy of visible and near-infrared light that is not absorbed and releasing this energy at the appropriate time.

3）How much does it cost to install a photovoltaic system?
The installation cost depends on the size of the system and the choice of components. Generally speaking, the initial investment is large, and the payback period is usually around 5 to 10 years, which varies depending on the region and the system design. For details, please consult the relevant power station construction companies.

4) Is it difficult to maintain the photovoltaic system?
The maintenance of the photovoltaic system is relatively simple but highly professional. The daily work mainly involves regular cleaning of photovoltaic panels, checking the operating status of the system and handling faults. Most installation companies will provide a certain period of warranty and after-sales service.

5) Is there a radiation problem with photovoltaic power stations?
Radiation can be divided into two types: ionizing radiation and non-ionizing radiation, and ionizing radiation is harmful to the human body. Photovoltaic power generation is non-ionizing radiation. Photovoltaic power generation mainly converts solar energy into electrical energy. Compared with daily household appliances, the radiation of the photovoltaic system is negligible, so it can be installed and used with confidence.

In general, installing a photovoltaic power station on the roof not only helps save electricity bills and protect the environment, but also improves asset utilization, and has become a new “green fashion”. However, before installation, it is very necessary to fully understand the characteristics of the photovoltaic system and related precautions to ensure long-term and stable returns.

Revolution of Indoor Photovoltaic Technology: Challenges and Opportunities of Solar Cells in IoT Applications

Against the backdrop of today’s rapid technological development, the increasing popularity of indoor Internet of Things (IoT) applications has made the prospects of smart homes and industrial sensors more promising. However, providing continuous and efficient power to these numerous devices has become a major challenge faced by various industries. Especially in indoor environments, traditional power supply methods are stretched, and the rise of indoor photovoltaic (IPV) technology provides a potential solution to this problem. This article will explore in depth the challenges and opportunities of indoor photovoltaic technology in IoT applications and reveal the future development direction of this field.

First, the foundation of indoor photovoltaic technology lies in its ability to adapt to lighting conditions that are different from those outdoors. Outdoor solar cells are usually tested under standardized sunlight, while the intensity and spectrum of indoor light sources are more complex. For example, LED lamps configured indoors can be divided into warm and cool colors, and their spectral characteristics are very different from natural sunlight. For this reason, the design of indoor photovoltaic cells must take this into account to achieve optimal energy capture. Therefore, the development of photovoltaic materials suitable for low light intensity and specific spectrum has become an important direction of research and development.

Secondly, one of the main challenges of current indoor photovoltaic technology is how to improve the conversion efficiency of cells. Existing crystalline silicon solar panels perform well in outdoor environments, but their energy conversion efficiency drops significantly in indoor environments. This is attributed to the fact that the energy band width (bandgap) of crystalline silicon materials is much lower than the ideal condition required for indoor photovoltaics. To improve efficiency, researchers are exploring third-generation photovoltaic technologies including organic solar cells (OSCs) and perovskite solar cells (PSCs), which not only have the advantages of adjustable bandgap but also perform well under low light intensity conditions. In addition, reducing the manufacturing cost of materials and improving the flexibility and loadability of equipment are also key to promoting this technological innovation.

Not only that, the market potential of indoor photovoltaic technology should not be underestimated. According to industry analysis, the indoor photovoltaic market is expected to exceed US$1 billion by 2030. In addition, the role of the Internet of Things in improving energy efficiency and reducing carbon emissions is highly anticipated. By optimizing indoor photovoltaic technology, IoT devices can not only achieve energy self-sufficiency, but also reduce dependence on disposable batteries and reduce resource waste. This move is not only in line with the current trend of sustainable development, but also an important part of smart city construction.

However, the development of the industry also needs to solve the problem of standardized testing. At present, the testing standards for indoor photovoltaics are relatively weak, mainly due to the complexity brought by the diversity of indoor lighting conditions. The International Electrotechnical Commission (IEC) has introduced some specifications, but they still need to be improved. Establishing consistent testing standards will not only help improve the competitiveness of the industry, but also enhance consumers’ trust in technology, thereby accelerating the popularization of the market. In addition, although indoor photovoltaic solutions are theoretically feasible, in-depth research on their stability and security is still needed to meet the needs of various IoT applications.

In the future, indoor photovoltaic technology will play an increasingly important role in the Internet of Things. With the continuous innovation of technology, indoor photovoltaics can not only provide sustainable energy support for billions of low-power nodes, but also achieve smarter and more efficient space management. To achieve this goal, cooperation between governments, enterprises and academia is essential. By strengthening research investment, promoting technology sharing and optimizing the policy environment, we can jointly accelerate the maturity and development of this industry. The advancement and widespread application of indoor photovoltaic technology will inject new vitality into the Internet of Things and pave the way for the realization of smart life.

In summary, although indoor photovoltaic technology faces many challenges in IoT applications, it has great potential. Through technological innovation, standard setting and cross-border cooperation, we have reason to believe that indoor photovoltaics will provide a continuous source of power for future smart life and drive society towards sustainable development.
