1. Installation and transportation
First of all, bifacial solar panels due to both sides of the absorption and conversion of solar energy materials make its weight is much higher than monocrystalline solar panels, according to relevant data show that the same size, the weight of bifacial solar panels is usually higher than the weight of monocrystalline solar panels about 5% to 20%, such as a 400watt monocrystalline solar panels weighs about 18kg, while the same size of the weight of the bifacial solar panels is about 20.25kg. For example, a 400watt monocrystalline solar panel weighs about 18kg, while a bifacial solar panel of the same size weighs about 20.25kg.
It is for this reason that the installation and transportation of bifacial solar panels takes more time, and if you hire workers to transport and install the panels, you will need to pay more for transportation and installation, which is something you need to consider before you buy.
As the back of the double-sided solar panel also needs to absorb solar irradiance, but the ability of the ground to reflect the sunlight is poor, so in order to improve the efficiency of the back of the power generation, you need to buy reflective devices, this device can reflect more sunlight for the back of the absorption and conversion, although the installation of reflective devices will increase the installation cost, but the later earnings will be greatly increased.
2. Thermal performance
Bifacial solar panels do not have a back panel with superior heat dissipation performance like monocrystalline solar panels, bifacial solar panels are glass panels on both sides, which makes the heat dissipation performance of bifacial solar panels worse than monocrystalline solar panels, and when it is in operation, bifacial solar panels are absorbing the sunlight on both sides, compared to monocrystalline solar panels, the heat will be a lot of heat build-up in bifacial solar panels, which may affect its service life. This may affect its service life.
3. Post-maintenance
Solar panels require regular cleaning of the glass panel to ensure that the solar panel can work properly. Bifacial solar panels need to clean the glass panels on both sides, which takes more time compared to monocrystalline solar panels.
Moreover, due to the unique design of bifacial solar panels, compared to mono solar panels, more frequent inspections are required for bifacial solar panels in order to keep both sides in the best working condition, which further increases the maintenance cost of bifacial solar panels.
4. Cost recovery
Although the cost of bifacial solar panels is higher than that of monocrystalline solar panels, the benefits are much higher than that of monocrystalline solar panels, so in terms of cost recovery, bifacial solar panels require less time than monocrystalline solar panels.
According to relevant data, the normal family use of standard solar panels, bifacial solar panels to build up the solar system requires about 7 years to recover costs, while monocrystalline solar panels to build up the system requires about 8 years to recover costs.
5. Space utilization
In order to reflective devices can work properly, reduce the shadow on the back of the double-sided solar panels to generate electricity, so the double-sided solar panels compared to monocrystalline solar panels need to be more spacing, which makes the installation of double-sided solar panels on the space requirements are greater than monocrystalline solar panels, the space utilization is lower.
Summary
Bifacial solar panels and monocrystalline solar panels are photovoltaic power generation equipment, is to promote the development of green energy indispensable thing, through the two kinds of solar panels in-depth understanding of the advantages and disadvantages of the solar panels, you can pick the solar panels more suitable for their own, which is conducive to the solar power equipment to better serve you.
