Why we Celebrate Chinese New Year in February? Interesting Facts.

Acting in solar energy field, it’s impossible to avoid China and Chinese relationships, cause it’s the biggest giant in PV industry. China is the biggest producer of PV modules, inverters and other solar technologies.

China is a very interesting culture, which is worth to study. So, why Chinese people celebrate New year holidays in February? What means red colour in China during holidays?

 

So, to start this interesting topic, we have to mention that Chinese new year is celebrated in February, not in 1st January, cause they are taking into account not Gregorian but Lunar calendar, and as the day is connected with Lunar calendar- a new moon birth, it’s not the same every year. The Chinese New Year day is being changed every year, but anyway it’s is being celebrated during February.

According to Easters calendar, China is celebrating not 2022 but 4720 year.

The real name of Chinese New Year is Chunjie, which means ,,Spring festival,,. They celebrate their spring festival with many similarities with Armenian people. First of all they pass the holidays with their families. They make traditional dishes, many of which include meat and sweets. They make a very family supper evening together. Chinese people like making gifts to each other.  The most common gift is money in red envelope, which symbolises luck in New Year.

And what is the meaning of the dragon? Why all New Year decorations are in red colour in China?

As we understood, Chinese New Year history is more than 4000 years. In pursuance of Chinese legend, a monster dragon named Nian (Nian means year in Chinese) comes every New Year and damages peoples’ houses, steels children and eats their food.

After some time, people understand that the only thing the Dragon is scared is red colour. They start to decorate their houses with red lanterns; they wear red clothes and make fireworks.

The other way to protect from Dragon is feasting and feeding the dragon. Chinese people place very tasty food near the house doors, for the dragon to carry them and be kind to people.

So, the legend of Nian Dragon made the Chinese holidays very specific and interesting to the whole world.

Is Solar Energy Actual and Workable During the Wintertime?

The most common myth about solar energy is that it’s not working during the winter. We’re very glad to announce that this claim is not correct.

 

So, now please pay attention to the facts:

  • Solar panels are working even in the winter, when there’s a sun. The most important is the sunshine presence.
  • We may say that the system keeps the same efficiency in the winter, as it does in the summer. The only reason the system produces less energy in the winter is that the sun hours are less than during the summer.
  • Technically: Solar panel silicone Is closed with a anti-glare glass, which absorbs maximum light.
  • In the same way, the solar panel absorbs the air temperature. Even in case a very small sunlight the panel gets much hotter.  So the snow melts and cleans the panel. That’s why we call solar panel a ,,self-cleaning product,,

 

So, as we understood, the glass of the solar panel influences on the system’s productivity during the winter time. It helps to absorb much energy.

 

How the cold helps or obstacles to the solar PV system?

What concerns to the cold, it only helps the solar panel work. The colder is the atmosphere, the less is the degradation of the PV module.

In many regions, where it is cold, solar systems have the best productivity.

 

Gegharquniq region is one of these regions in Armenia. This is a place where is very cold, but not foggy.

 

Is it needed to serve solar panels in the winter?

In general, solar panels are classified to the products, which don’t need any service.

As we mentioned above, the snow Is melting down from the solar panel even in case a small sunlight. But there’re some regions, where it’s wet and the snow is becoming ice, sticking on the panels. In this case it’s better to clean solar panels, but through solar panel cleaning specialists.

 

What concerns to solar panel productivity, we have to repeat that the system produces less during the winter, but it’s because of less solar hours. But we have to mention a very important fact: as the PV is producing more energy during the summertime, which is being accumulated, there’s a possibility to use the accumulated energy during the wintertime. So, we have a compensation of energy in the winter.

So, even the wind, snow, cold don’t make an obstacle to have a eco friendly energy from sun. So, why to wait? Why to lose summer sunny days and not to install solar PV system to become energy efficient.

When the solar panels are dying? Recycling of solar panels

Alternative energy is realized as an eco friendly technology, but what happens to this technology, once they reach the end of their lifetime?

The solar industry, which is one of the biggest fields of the alternative energy sources, continues developing and fighting against the climate change. In 2008 5.5 GW capacities was installed in all over the world, which produced total 15 GW energy. The installed total capacity grew till 22 GW in 2013. The industry keeps going on today.

However, the experts are existed whether the solar energy is really as green as we imagine. In any case, it is manufactured in factories; it is demanding grow materials and can leave wastes, it has lifetime and after the lifetime, it has to be recycled, if not, it’s becoming a rubbish and no eco anymore.

The solar experts are sure: Manufacturers must have responsibility and recycle the manufactured solar panels after 25-30 years and more. For example, PV modules contain glass, aluminium, which may be successfully used for another production or even for solar panel.

The problem that the PV modules are not old enough and cannot provide enough volume to start recycling, so the PV recycling start-up has to start with collecting solar panels for a while and then open a manufacturing.

Anyway, this issue is so essential, that the European Commission undertook it and started development. The members of this commission have signed a joint declaration and accepted to collect minimum 65% of solar panels installed in Europe since 1990 and recycle the 85% of the waste.

 

So, from the view of the business: How are the PV panels recycled? Who will be responsible of following the PV module lifetime and collecting them?

  • The exploiter: The owners /houses or businesses/ are responsible to collect damaged or old solar panels and deliver to the PV recycling company.
  • The manufacturer and electronic companies: The manufacturer is responsible to collect the batteries, junction boxes and so on and recycle, reuse them.

From the view of the economy, the recycling company itself is interested in getting the recycling materials and will pay to organize the process of course, but will it be profitable for it?

Many economists and experts share that the PV recycling is not financially viable today, in the absence of a carbon price. It’s of course clear that the PV recycling is quite profitable for the PV manufacturer, but will it be ok from the view of carbon taxes or carbon prices.

However, many manufacturers have developed a plan: how to make a recycling just in the PV manufacturing process.

The First Solar is one of these companies which finance a PV recycling program.  They are separating the panel into glass, metal and electronics. The components are being recycled just in the factory and being reused for the PV module manufacturing.

The Perfect Place to Install Solar Panels. Where and How?

Whether it’s possible to install solar panels anywhere? The most frequently asked question has one answer-question: Will it be possible to plant a garden in anyplace not considering the issue of light, water and ground.

Just like plants, the solar panels also need the highest light rate, which is the most important factor for the PV installation.
The solar PV station slope, azimuth are the most important factors during installation, so it’s not possible to install without the site study. It’s not the same to install solar panels on the house wall vertically or on the rooftop horizontally. The efficiency will be very different. Everything matters.

The solar PV installation is not a small investment, so it must be ideal to trust the pre-installation studies to a specialized team, who will examine the solar potential, roof or relief. In common, the solar panels are being installed on the rooftop with an exact way, with solar metal construction. This is because the solar PV is the most efficient when having a slope to south. So this is the reason, that every customer must ask himself: What is the most important reason he installs the solar panel: energy efficiency, gas reduction or just the solar PV existence on the rooftop.

In general, the most common place to install solar panels is the rooftop, especially when it’s residential project. But it’s also possible to install on the ground like a cover, roofing, parking and so on. Depending on the site features, climate and other factors, the listed above constructions may all produce the highest efficiency and solar power if installed with ideal technical standards.

Just within this theme, we’d like to talk about the solar PV installation price, which depends the installation features, whether it’s on the roof or ground. In case of ground mounting, the price is higher for concrete and metal construction height. So this is the reason, that Eco Step Green Energy Solution Company never publishes fixed prices. The most professional approach is to study the site, make a solar examination and then make a material price list.
However, where is the most convenient place to install solar panels? Everywhere is possible, and everything depends on the site features.

Some Features of Solar PV System Installation

At first, we have to understand what the solar panel is, as it’s the most important element of the PV system.

The solar module / solar panel is a union of photovoltaic elements, which produce direct current. The solar panel is just a simple structure, which gives many visible advantages to its user, such as:

  • Decrease of utility, electricity costs.
  • Reduce of greenhouse gases.
  • Minimum costs of exploitation.
  • No noise pollution.

Solar panels may be monocrystalline and policristalline. They both are made from crystals.
To explain with the simplest words, a solar panel is an aluminium rectangle frame, which includes crystals and closes with special, protection glass. The glass has ideal transparency, so it helps the sun rays to penetrate inside. There are also some other type, flexible solar panels, without a frame, which are using for sticking on walls, on cars, tracks and so on. The efficiency of these panels is not as high as the simplest panels with frame.

So, concentrating only in solar panel technical characteristics and quality is not correct, cause in global, the productivity of solar panel is mostly depending on solar inverter, battery and other components characteristics and quality.

And so, let us introduce what are the core components of the most complicated solar PV system:

  • Solar panels (modules), which produce DC from sun rays. 
  • Controller, which is responsible for charging the batteries. 
  • Solar inverter, which may be both three phase and single phase. This depends of the user’s network. 
  • Batteries.

For the first phase of solar panel manufacturing process, some researchers are being done to use special high quality components and materials, which will be able to be exploited even in  -35 °C – +80 °C temperature terms.

The solar PV connection scheme may be introduces by the following way:

  • DC is going to controller with good quality, three phase insulated cables.
  • DC is dividing in two branches: One of the branches goes to house, which will be used by the user and the second branch goes to solar battery, where it’s being collected.
  • DC is passing to battery by solar inverter, where it’s being made three or single phase. The solar inverter responds for making the current 220V or 380V.
  • The alternating current is being distributed in junction box, after what it passes to feed all the equipment of the house.

However, the main reason to invest in solar PV installation is energy saving. For the excellent productivity of the PV system we have to take into consideration some factors such as the ideal site, no shadegood azimuth and slopeno high temperature and so on. We have talked and we’ll talk much for the role of these factors in our previous and next blogs.

To gain highest productivity, it’s very important to tilt the panels to south. The slope is already depending on the climate characters of the region, such as fog, temperature and so on. But anyway, the ideal variant is to change the tilt two times per year, in winter and in summer.
In the case, where solar panels are installed on ground, we need to consider also the snow load, so the solar structure, the mounting system must be higher. The height depends on the snow load of the region.

Average Lifetime of solar PV Modules

Solar energy is being used in energetic field since the 1800s as we know. Famous French physician Alexander Edmond Becquerel was the one, who invented solar energy as an energetic and thermal solution in 1839, using also magnetic and optical forces.
Many countries try to boost the solar energy field and support the development by creating a profitable legislation field and loan terms for individuals and businesses to have energetic freedom and to solve ecological problems.

How many years will the solar PV module be exploited?

But anyway, the more people realize the profites of solar energy, the more they start to ask questions. One of these questions is: How many years will the solar PV module be exploited? How to prolong the solar PV panel’s productivity.

However, the guarantee of solar PV module’s productivity is given by the manufacturer, that’s why it’s important to collaborate only with certified, experienced solar PV manufacturers. Eco Step is proud to announce that all PV and solar inverter producers are classified in top 10 quality world manufacturers.
Offering only premium class solar products, Eco Step gives big importance also to installation quality and professionalism. Having a reliable product is not enough to guarantee long lifetime of the solar PV system. Eco Step Armenia ensures the PV system’s security and highest productivity, being sure in protection systems’ quality and long lifetime.
So, depending on the solar brand that the client will choose, Eco Step will provide more than 30 years of linear performance guarantee with 15-25 years of product warranty with free service.

Type of Solar panels

Anyway, solar panels are classified in two, big types: Monocrystalline and polycrystalline. There’re many opinions about the lifetimes of these two types, but we have to mention that it’s not professional to give advantage to one type, because the panels act differently in different regions and climate terms. For example, monocrystalline solar panels are better in cold, but not so foggy regions. Policrystalline solar panels have longer life period in very hot regions. But anyway, the advantage is for monocrystalline solar panels in Armenian climate terms. The monocrystalline solar panel will give more efficiency also. It needs fewer surfaces and produces more energy.

So, giving a big importance to the development of solar energy field, countries try to influence on solar panel and solar inverter producting quality, that’s why they demand quality and special certification for companies, which produce solar PV. The certificates are demanded also for every production series and every solar module with an exact code.

However, talking about solar PV module productivity, we have to take into consideration also the external factors which influence on PV system effiency:

  • Solar PV panel slope and azimuth
  • Climate terms of the region
  • Solar PV module’s systematically cleaning and service
  • Shadows
  • Temperature of the region

Of course, except climate terms and PV module cleaning, it’s very important to provide mechanical security during the installation. If any damages be on the solar panel, it will have more degradation during the year.

This is the reason, that we take into consideration not only the manufacturing quality of the product, but also the work quality of installation team.
