In the article below, you will better understand the cost of professional photovoltaic systems, so that you can form an idea of the investment required for your business.
Key Points of the Article:
- A selection of high quality photovoltaic solar panels, constructed from more durable materials.
- Select inverters with reliability and after sales service as this is the most sensitive part of a photovoltaic system.
- Do not ignore the quality of photovoltaic mounting structures.
- Make a careful selection seuss designers and installers of the system.
- Focus primarily on the value provided by the photovoltaic system in your business in the long term, and to a lesser extent in cost.
Green energy, renewable energy sources, global warming and the protection of the environment of unknown words in the past decades have become a daily topic of conversation. In addition, the increases in electricity bills, which are expected to become even greater in the coming months, are already a very important outlet for businesses who are trying to find their feet in the post-covid19 era.
The auto-production of energy through photovoltaic systems, in particular with the energy clearing ( net – metering) presented as an economic solution that will allow professionals to maintain their viability.
However, just like any other investment, special attention is needed in choosing the right supplier for photovoltaics to ensure that there will be neither overpricing of the project nor a reduction in quality in order to lower the price.
How is it calculated, however, the cost of professional photovoltaics? A quick and easy way to grasp the real cost of a system is to consider separately the different components that make up the solar installation.
Cost of professional photovoltaic: The utility grid have the greatest cost
The photovoltaic modules or panels are the key component of the system. Are the ones that absorb the solar radiation which is then converted into electrical energy.
The technology of the frames has made leaps of progress in the last few years. Now, coupled to the reduction of the volume of each panel, with the simultaneous increase of the Watt-absorbing.
A few years ago the most common panels in the market was rated power of 220W and occupied around 1.5 m2. Today we are in the era of the panel power 530W over 2 m2. That is, 240% more strength in just half a square measure above.
The explosion in demand for solar panels has resulted in the creation of multiple, huge in size, production companies frame. As with all industries, in energy, there are companies that stand out for their quality and durability of their materials. There are those who are trying to offer good quality at a good price. There are others that are lagging behind in quality but superior in price.
The first two categories of companies usually have their headquarters in Europe. There is carried out the study and the design of the frame. The third category consists of companies located in Asia. It is worth stressing here that the essential difference between the frames of the various companies is the quality of the materials it has been decided to be placed. Plants, almost all of the companies are located in Asia.
The difference between the frame does not have a direct impact on the output results of the system. After ten or twenty years, however, the reduction in performance is noticeable. Generally, as a price range, it is worth noted that a reliable panel costs around 0,33€/Watt.
Select reliable inverters voltage (inverter)
The second most important factor to consider for the cost of professional photovoltaic systems is the inverter used. Solar radiation, as it hits the photovoltaic panel, generates direct current (DC) within it. However, direct current cannot be used directly, as homes use alternating current (AC). Therefore, a photovoltaic installation includes an inverter which is responsible for converting the current to alternating current. This way, it can be used in the home and excess power can be fed back into the grid of the HEDNO.
Toss corresponding with companies in the production of photovoltaic modules were and those who create inverters voltage. The market is filled with options for every budget. Colossi of telecommunications have been in the industry. At the top of the preferences of the consumers, but, thanks to the reliability and after sales service are the companies based in Germany.
The cost of the inverters is not possible reduction in Watts, as well as the larger the inverter, the lower the cost per Watt. Because, however, it is the most sensitive device of the system, which is accompanied with a shorter warranty, compared with the other parties, interested parties are advised to trust the companies with the greatest reliability even if their price is higher.
Don't ignore the important role of the base of support of a photovoltaic
The mounting of the photovoltaic modules constitute a particularly important part of the installation, in which, however, rarely given the attention it deserves.
The most common choice are the bases are made of aluminum and this is the main reason that the photovoltaic systems exhibit increases in prices in the last period. The installation on the roof is a more expensive option compared to the installation of a roof, as it required much larger volume of material to achieve the optimal support of the panels.
The cost of the base can be calculated roughly around us $ 0.10/Watt if this is an installation on the roof, while if the installation is to be made in the roof, then the cost is 0.13€/Watt.
Because the bases are not present any particular difficulty in making them the most important thing that must be taken care of is the existence of the necessary certifications for adequate static installation and resistance to wind loads and weather conditions. In this way, there is the assurance that in any difficult weather conditions will not cause an accident that can cause great inconvenience.
Electrical equipment: cable and gauge system
This category is part of all the electrical equipment that is used for the completion of the installation. In particular, the cables and the system counters. As is easily understood, there are thousands of different kinds of cables that can be used for the installation of a photovoltaic system.
It is a fact that the better the cable, the greater and the duration of life. The sharp increase in the price of copper has embraced the values of all the wire. In many cases they appear, and problems of shortages of stock.
The meters on the other, are the only part of the photovoltaic equipment where the options are few. This is due to the mandatory certification that needs to be done in the meter of net metering by the board HEDNO who has given a list of a number of counters which can be the option.
Their function is exactly the same. It is responsible to measure with accuracy the electricity generated by the photovoltaic and gives the HEDNO in order to make the set-off between produced and consumed, and the cost of them.
A great deal of attention in the office you choose to study, licensing, and installation of photovoltaic
It's so great is the area of the renewable energy sources that anyone, is presented as an expert. Many declare themselves ready to take on the completion of a quite demanding process. A process consists of the design and licensing of a photovoltaic system.
Initially, the precise dimensioning of the system and the optimal location so as to avoid shadows and to ensure the maximum output power might sound a simple process but many times it is terribly complex and if done incorrectly, is not susceptible of correction.
Consequently, if the management of the licensing process is not handled correctly, it can lead to significant delays. It may even result in the rejection of the licensing request. Therefore, it is clear that if the choice of the engineer responsible for the photovoltaic system is made purely based on financial criteria, there is a risk of creating failures that could either result in the project not being completed or in the presence of issues that would be detrimental to the self-producer.
There is a similar logic to be followed in the installation of the system. The quick and economical completion of the project does not necessarily mean that it's the right one. Any mistakes in the installation of the base, the panels and the inverter may cause major damage. So the building will be installed, with water leakage from the roof, or the roof, and on the same equipment, which may suffer irreversible damage and, ultimately, to raise the cost of installation instead of decreasing.
Cost of professional photovoltaics: How much money should I invest?
The conclusion is that the entrepreneur – a professional who is interested to invest in a photovoltaic system for his business, has a lot of options. From cheapest to most expensive.
The decision on the quality of the investment will take it himself. In this article, we have presented the key factors that you need to evaluate in order to put a price correctly the size of the investment.
There is a system for €850/kW, with of €1,000/kW, with €1.150/kW. The businessman – professional will take the decision of how much money she wants to make available and to consider his options.
We emphasize, however, that the solar is an investment with great depth of time (25 years). I would suggest the cost to be the sole factor in making a final decision. Focus on the value you will offer a quality photovoltaic in your business and not so much cost.
Don't forget to give importance to the proper choice of the partner who will undertake the design and installation, as well as mentioned, the efficiency of the photovoltaic and all the work is in their hands.
