I found that the installation of solar photovoltaic panels on the roof, which became popular in the past few years, has really received mixed reviews in recent years. Many people think it is suitable, and those who think it is not good also stick to their own ideas.Why do people on both sides have different opinions? Is it good to install solar panels on the roof?Today, I will simply talk to you about the things about installing solar panels on the roof.
The advantages of installing photovoltaics on the roof are actually very obvious, mainly reflected in three aspects.The most obvious is clean energy, saving electricity and money. Many photovoltaic power generation systems are connected to the grid. Generally speaking, whether it is for self-use or sold to the grid, there are certain subsidies, and electricity consumption is equivalent to saving a lot of money.
Secondly, after installing solar panels, there will also be a rent for renting the roof, but it usually takes 25 years, and there is a one-time subsidy. Many families live in old houses in the village, and they usually don’t live in them. They will choose to agree, which is also a reasonable use.
In addition, the roof is equivalent to an extra barrier. As long as the structure of the house is fine, the installation of photovoltaic panels will be more sun-proof and rain-proof, which will make the roof more durable.
What situations are not recommended?
But in fact, there are some situations where it is not recommended. At least you should carefully consider installing solar panels.
Aging of the house structure
There is no need to say much about the aging of the house structure. Solar panels still have a certain weight. If the house is an old house, it has been in disrepair for a long time, or there are places that have been aged and damaged, it is recommended not to install solar panels rashly to avoid causing greater damage to the house structure.
Poor roof sunshine
Secondly, if the roof sunshine is not good, then whether it is for self-use or connected to the grid, the efficiency is not high. Many photovoltaic installation companies will also conduct tests. For roofs with poor sunshine, such as north-facing, shaded by trees or buildings, they will be evaluated and are often not suitable for installing solar panels.
Need roof drying
There are also many friends living in the village who need to use the roof space to dry corn, clothes, bedding and other items. The roof is equivalent to an extension of the floor of the house. In this case, you have to weigh the pros and cons and decide whether you need photovoltaic power generation or use space.
Small roof area
A small roof area is also a disadvantage for installing photovoltaics. As we all know, solar panels need a large light-collecting area to effectively generate electricity. If the roof area is too small, it will inevitably affect the efficiency of power generation, and there is no need to install it at this time.
Requirement for the beauty of the house
Oh, yes, there is another situation, that is, friends who have requirements for the beauty of the house.After installing photovoltaic panels, it is definitely not as good-looking as the original brick and tile structure of the house, and when the sun is strong, the photovoltaic panels on the top of the house will also have the problem of dazzling. It has to be said that many people give up installing solar panels for aesthetic considerations.
Poor roof material or too inclined
Finally, there is the problem of the roof. Some non-standard shingle materials or inclined roofs with too tricky angles are generally not considered to install solar panels. The former is the same as the structural problem mentioned above, and the latter is because of the angle of sunlight, which will also affect the power generation efficiency.
In Conclusion
Seeing this, it should be clear to everyone whether to install solar panels on the roof.
Personally, for old houses that meet the conditions and are not often lived in, installing solar panels is also very beneficial. Not only is it a new energy source, but there are also certain subsidies. Although it is not too much, it is better than being idle.But if there are any of the above 6 situations, you still have to make a careful decision. After all, a contract is often signed for 25 years, and changes in the middle should be considered in advance.
