There is no doubt that the sun is the greatest source of energy for mankind. Although human beings can only capture part of solar energy, if we can make full use of solar panels and solar energy, it will bring significant changes to the world.
With the increase of capital reserves of solar panels and the increasingly fierce competition in market costs, solar power generation has become the main energy source for more and more families.
In the past few years, this technology and solar cell storage technology have developed rapidly, making solar energy an effective clean energy.
However, one kind of energy always has its disadvantages. This article will discuss some advantages and disadvantages of household solar panels.
Advantages:
1. Reduce electricity expenditure
When the power generated by the solar power generation system meets the household energy demand, the household energy expenditure will be reduced, and the amount saved depends on the scale and energy consumption of the system.
For example, if the user’s family has a large population and invests in solar energy for the house, this transformation may bring great benefits, because most of the original energy expenditure of the family is covered by large-scale solar power generation systems.
In addition, the solar power generation system can not only save power for users, but also sell the remaining power to the transmission network when the power generated by the system is more than the actual use.
2. Renewable energy sources
One of the main advantages of solar panels is that solar energy is renewable energy, which can be used every day and is suitable for all regions of the earth. Solar energy is different from other limited energy sources. It is impossible for mankind to consume it.
As long as the sun shines on the earth, solar energy can be used. Scientists predict that the solar energy will disappear in 5 billion years. They hope that humans can enjoy the sun during this time.
3. Low maintenance cost
Generally speaking, the solar power generation system does not need too much maintenance. It only needs to keep it clean. Cleaning it several times a year is enough. Users can either clean by themselves or ask professionals to clean.
If the solar panel manufacturer is reliable, it will generally provide users with a warranty period of 20 ~ 25 years. Because the solar panel has no moving parts, there is no wear.
Generally speaking, the inverter is the only component that needs to be replaced, which needs to be replaced every 5 ~ 10 years, because solar energy is constantly converted between electric energy and thermal energy (i.e. between solar photovoltaic and solar thermal energy). In addition to the inverter, users must also maintain the cable to ensure the maximum benefit of the solar power generation system.
When using solar panels, users need to pay relatively low maintenance and repair costs after paying the initial system cost.
Disadvantages:
1. Vulnerable to weather
In rainy days, the effectiveness of solar power generation system will decline, because solar panels rely on sunlight to effectively collect solar energy. Therefore, smog, humidity and other weather will have a significant impact on the power generation system. In addition, the system cannot capture solar energy at night.
On the other hand, if users also need hot water at night or in winter, thermal power battery panels can be used instead.
2. Expensive storage space
Solar energy must be used immediately or stored in huge batteries. These batteries can be charged during the day and power off grid solar systems at night.
This is a good solution that enables users to use solar energy around the clock, but the cost is quite expensive.
In most cases, it is wiser to use solar energy only during the day and other energy sources at night. However, users can only do so when the system is connected to the grid. Fortunately, users usually need more electricity during the day, so solar energy can meet most of their needs
3. Large occupied space
The more electricity you want to produce, the more solar panels you need to collect as much solar energy as possible.
Different types of solar panels occupy different space, but most solar panels need a lot of space. However, some users’ roofs are not large enough to accommodate the number of solar panels required for energy production.
Some solar panels can be installed in the yard, but the installation position must be able to receive sunlight. If the space for installing solar panels owned by users can not meet the expectations, they can still install fewer solar panels to meet certain energy needs.
This also means that users will not be able to run the entire power system through solar energy. In addition, due to the need to connect to the power grid, users still have to pay part of the electricity bill.
However, in most cases, users who are able to purchase and maintain solar panels usually have a house large enough to meet their needs for placing solar panels on the roof.
