Renewable energy sources have penetrated the daily lives of Greeks due to circumstances that have arisen primarily from two factors. First, the continuous increases in electricity costs are one of the main problems that professionals face. They find themselves in a difficult position deciding whether to absorb part of the increases, thereby reducing their profits, or consider increasing prices and losing part of their competitiveness.
The second reason more and more people are turning to green energy is the discussion surrounding climate change. The problems arising from ecological destruction are expected to intensify in the coming years. One of the most immediate ways to address the issue is to move away from coal burning for electricity production. The burning of lignite is one of the main reasons for the emission of pollutants responsible for the greenhouse effect.
However, it is entirely reasonable to have reservations about the transition to green energy. As has happened in the past with all pioneering systems at the beginning of their operation, this article aims to answer some of the most fundamental questions that anyone interested in installing a photovoltaic system on their roof may have.
Frequently Asked Questions About Photovoltaics #1: Is it really worthwhile for me?
The first thought that comes to every professional’s mind is understandably the economic benefit they will gain from such an investment. Certainly, the initial capital required cannot be considered a negligible amount, mainly because it needs to be paid upon the completion of the installation of the system. In contrast, the existence of a monthly electricity bill may give the impression that the required amount is smaller, but the reality is quite different.
For example, a professional needing 20 kW to fully meet their energy needs will need to pay an amount of around €20,000 to install a reliable photovoltaic system. However, if they remain in the existing form of electricity supply, then, without considering the upcoming increases, they would be expected to pay at least €400 per month, which means that in 4 years, they would have already paid the amount of €20,000.
If we also calculate what they will have paid at the end of the twenty-five years based on the current state of the energy market, we arrive at the enormous amount of €120,000. It is easily understood, therefore, how great the profit is for the professional who will become self-producer of the energy needed for their business.
Frequently Asked Questions About Photovoltaics #2: What are the maintenance costs of a system?
We are accustomed to every investment having what are known as the small print clauses that reduce the costs initially promised to the investor. It is reasonable, therefore, that there is a search in photovoltaics for points that could create future costs and burdens outside of the initial program. Usually, the first thought of most people focuses on the maintenance costs of the system, which is not unreasonable considering it is a technological installation exposed to weather conditions.
The reality, however, is quite different as photovoltaic systems have evolved to such an extent that the interventions needed after installation are minimal. Specifically, the panels are manufactured to specifications that withstand weather conditions for many years, while the only maintenance cost, aside from damages caused by hail, is an annual cleaning with water and common commercial detergents.
For the mounts, similarly, the only care required is tightening the screws once a year for two years so that the system takes its final form due to expansion and contraction. Finally, the inverter does not require any care as long as it is within the warranty period, but after five or ten years, depending on the warranty offered by the supplier, a typical check is recommended.
In this way, the admittedly short list of maintenance tasks required for a photovoltaic system is completed, regardless of its size. Therefore, it becomes clear that there are essentially no maintenance costs, as most tasks do not require specialized personnel or lengthy work.
Frequently Asked Questions About Photovoltaics #3: How will it fit on my small business roof?
The progress of photovoltaic technology has led to a dramatic increase in the efficiency of a system while keeping the size of the installation stable. A decade ago, the photovoltaic panels commonly available in the market had a nominal power of 220W and covered a little less than 2 square meters. In contrast, today, the power of each panel has more than doubled, reaching 530W without changing the size of the construction. Thus, in a roof that can accommodate 20 panels, a system that could previously be installed with a capacity of 4.4kW can now have a capacity of 10.6kW.
Another factor that should be taken into account by professionals who hesitate due to a lack of space is the assistance provided by legislation for installations. Specifically, current legislation allows photovoltaic installations on roofs and terraces of buildings, but not only. The system can be placed on the ground or on a canopy of an auxiliary building or parking space, and panels can even be installed on the façade of the building. In short, installations can be placed anywhere the professional wishes, with the only condition being that it must be a legally constructed building or an regularized unauthorized structure.
Frequently Asked Questions About Photovoltaics #4: Will it create problems with the roof insulation?
One of the most widespread objections encountered in the transition to green energy concerns how the panels are installed on the roof or terrace and whether it will affect the insulation of the space. It is entirely reasonable to have this concern, as improper installation can create serious issues with the building's insulation, both functional and aesthetic, leading to additional correction costs.
The only sure way to avoid this issue is to entrust the installation of the project to companies with extensive experience in the field of photovoltaic installations, and the quality of their work speaks through their projects, such as ΙΩΝΙΚΗ Renewables. Do not hesitate to ask them to show you some of the photovoltaic installations they have already completed or to talk to people who previously chose the company you are considering.
Additionally, the most significant mistake that individuals interested in photovoltaic installations make is attempting to save some money by choosing companies that lack the necessary experience in photovoltaic installations, resulting in frequent problems. This ultimately leads to the installation costing more for the interested party than if they had initially trusted a well-established company in the field, due to the additional repairs that may be required.
Frequently Asked Questions About Photovoltaics #5: I want to install photovoltaics, but let's wait a while
A large number of business owners and residential consumers understand the benefits of a photovoltaic system but either due to cost or different priorities choose to postpone the installation of the photovoltaic system for another time. However, this is now proving to be a wrong choice, as the significant increase in the number of new installations has led the network to the brink of saturation.
The margins for new renewable energy installations are rapidly decreasing, with many areas of the country already beginning to reject applications for photovoltaic parks. The reason for this saturation is that the energy produced by photovoltaics must be transferred to the nearest substation of the network, and from there it must be absorbed and distributed. However, the substation has a maximum limit of energy it can absorb, and when that limit is reached, HEDNO (Hellenic Electricity Distribution Network Operator) stops accepting new applications for photovoltaics.
Thus, the possibility that new permits will stop being issued, as happened in 2012, seems more tangible than ever, with no one being able to predict when the system will reopen. Therefore, postponing the decision to install photovoltaics may lead to an inability to carry out the installation when the idea has matured well in the minds of the interested party, who will see their bills continuously increasing. Moreover, considering the time it took after 2012 for permits for photovoltaic installations to be issued again, it seems imperative to expedite decisions and processes for those who want to benefit from green energy.
Epilogue
The uncertainty that accompanies any investment and the doubts regarding the disbursement of an amount for the transition to green energy are completely natural. Another spike in electricity prices, which all indications show will continue to rise, presents a prime opportunity for interested parties to contact experts in the field of photovoltaics to discuss the above and many more potential queries they may have.
Choosing a reputable company in the field of photovoltaics, such as ΙΩΝΙΚΗ Renewables, is the most reliable solution to alleviate all doubts with the expertise of the company’s staff, helping you take the leap into the future of green energy, leaving competitors behind while also contributing to the protection of the environment.
