Myths on solar energy – the truth about photovoltaic panels

The most common myths about the efficiency of the solar panels Solar panels do not work in cloudy or winter day One of the most popular myths on solar panels is that they are not effective in cloudy or winter days. Although the production of energy is influenced by the intensity of sunlight, photovoltaic panels continue to work even in less favorable weather conditions.

Even if the sky is covered with clouds, the panels can generate energy due to the diffused light. Solar radiation does not disappear completely in the terrible days and the modern panel technology allows the capture and conversion of part of this electricity light. Depending on the density of the clouds, the efficiency of the panels can decrease by 10-50%, but the system continues to produce energy.

In winter, many believe that low temperatures influence panel performance. In fact, solar panels work more efficiently at lower temperatures, because overheating in summer can reduce their performance. As long as there is light, the panels continue to produce energy, even when temperatures are negative.

In conclusion, although the production of energy can vary according to the weather conditions, the photovoltaic panels remain a practicable solution throughout the year, even in the cloudy days and in the cold season.

How to produce energy a photovoltaic system even without a strong sun

A photovoltaic system does not need a shining sun to work. Capture the sunlight and transforms it into electricity and this process can also be done in days with the covered sky.

Solar panels are designed to use both direct and diffused light. When the sky is covered by the clouds, the sun’s rays are dispersed, but the panels continue to capture this light and produce energy. Even in days with rain or snow, solar radiation still reach the surface of the panels, allowing them to work, although to a lower capacity.

In addition, panels performance are influenced by the technology used. The monochristalline panels, for example, have greater efficiency and are more suitable for areas with long or many cloudy days. Another important factor is the installation corner of the panels, which must be optimized to maximize the capture of light throughout the year.

In addition, photovoltaic systems can be completed with batteries for energy storage. This allows the use of energy accumulated on sunny days, even when production decreases due to the adverse time. Therefore, solar energy remains a practicable solution regardless of the weather conditions.

Solar panels are not profitable and investment recovery takes too long

Another common myth is that photovoltaic panels are not a profitable investment and that it takes too long until the recovery of the initial cost. In reality, given the increase in electricity prices and the existence of subsidies, the recovery of the investment is performed faster than in the past.

A large photovoltaic system can reduce the electricity bill of 50-80%and, in some cases, even completely. This means that the monthly economies reached by producing their energies will cover the initial cost of the investment over time. Depending on the size of the system and the consumption of the house, the amortization can be performed in 5-7 years and, after this period, the energy produced is practically free.

In addition, the House Photovoltaic Green program offers a subsidy of up to 30,000 she, significantly reducing the initial costs. This financial support causes the investment to be much more accessible and accelerates the period of recovery of money.

Another aspect that increases the profitability of the panels is the possibility of becoming a prosumer. This means that the excess of energy produced can be injected into the network and the owner of the system receives financial compensation for the energy delivered. Therefore, the additional income from the energy produced can contribute to the fastest recovery of the investment.

In conclusion, photovoltaic panels are a long -term profitable solution, providing significant savings and protection against electricity prices fluctuations.

Photovoltaic panels break quickly and require constant maintenance

Another common myth is that photovoltaic panels are fragile and break easily, which require constant maintenance. In fact, solar panels are designed to resist extreme weather conditions and have a life of 25-30 years, with a minimum efficiency loss over time.

The photovoltaic panels are made with resistant materials, such as safe glass and anodized aluminum, which are tested to cope with strong winds, hail and great variations in temperature. Most manufacturers offer guarantees of 20-25 years, which demonstrates their long-term reliability.

As for maintenance, the panels require very little intervention. Usually, occasional cleaning is sufficient to remove dust, leaves or dirt deposits that could affect the efficiency of the system. In areas with frequent rains, this cleaning is made naturally, without the need for the owner.

The component that requires more careful checks is the inverter, the device that transforms the energy produced by the electricity panels that can be used at home. The inverters generally have a shorter duration than the panels, about 10-15 years and can request replacement at a certain moment. However, these costs are reduced compared to long -term savings.

In conclusion, photovoltaic panels are reliable, durable and do not require constant maintenance. With a correct installation and periodic minimum checks, a photovoltaic system can work effectively for decades, providing clean and sustainable energy without high maintenance costs.

Myths on costs and installation

Solar energy is too expensive and inaccessible

One of the most common myths about sun energy is that it is too expensive and inaccessible to most people. Although in the past the costs for the installation of a photovoltaic system were high, today prices have decreased significantly, making this technology more accessible than ever.

A factor that contributes to the accessibility of solar energy is technological development. The production of photovoltaic panels has become more efficient, which led to reducing production costs and, implicitly, at a lower price for consumers. In addition, the efficiency of the panels has increased, which means that fewer panels is needed to generate the same amount of energy.

In addition, many people believe that the initial investment is too large and difficult to recover. In fact, due to the economies made on electricity invoice, a large photovoltaic system can be amortized in 5-7 years and, after this period, the energy produced is practically free.

In addition to these aspects, there are also multiple financing options, including green credits and solar energy leasing, which allow the purchase of a photovoltaic system without a large initial investment. Therefore, solar energy is no longer a luxury, but a sustainable and accessible solution that is more and more people.

How the subsidies and lowering prices make solar energy more accessible than ever

In addition to reducing the prices of solar panels, government subsidies play an important role in increasing the accessibility of solar energy. In Romania, the Casa Photovoltaic Verde program offers financing up to 30,000 she for people who want to install a photovoltaic system. This subsidy can cover much of the initial cost, significantly reducing the amount that the beneficiary has to pay.

In addition, in addition to the state funding, there are also support patterns, which allow the surplus of energy on the network. Therefore, not only by saving money by reducing the electricity invoice, but you can obtain an additional income by marketing the energy produced.

Banks and financial institutions have started to offer green loans with preferential interests for renewable energy investments. Therefore, even those who do not have immediate financial resources can access a photovoltaic system and can recover their investments from the monthly economies made.

By lowering the prices and existence of various forms of funding, solar energy has become one of the most accessible and profitable sources of renewable energy, being a practicable solution that is more and more families.

The installation of photovoltaic panels is complicated and lasts for a long time

Many people hesitate to install photovoltaic panels because they have the impression that the process is complicated and takes a long time. In reality, due to the development of technology and experience acquired by authorized installers, the entire process is simple and well organized.

The first step is to choose an authorized installer, which deals with everything related to the design and installation of the system. In most cases, the installation company also deals with the documentation necessary to obtain funding, so that the owner should not be actively involved in the bureaucratic part.

The effective duration of the installation of a photovoltaic system varies according to its size, but usually does not last more than 1-2 days. After installation, the system must be checked and put into operation, which can take several days, depending on the procedures of the energy distributor.

The process of approval and obtaining funding through photovoltaic green house can take longer, but it is not the complexity of the assembly, but the time necessary to verify and approve the documents from the authorities.

Therefore, the installation of photovoltaic panels is not complicated and, once a reliable installer is chosen, the entire process is managed in a professional and stressful way for the beneficiary.

Solar panels influence the roof structure

Another common myth is that photovoltaic panels can damage the roof structure or cause water infiltration. This is false, because the correct assembly of the panels is performed without compromising the integrity of the roof.

The panels are installed on special tightening systems, which are designed to distribute the weight uniformly and not to exert excessive pressure on the roof. The materials used are corrosion resistant and do not influence the long -term structure.

In the case of inclined roofs, the panels are mounted on supports fixed with the help of sealed screws, which prevent any possibility of infiltration of water. For flat roofs, special structures are used that do not require direct blocking, thus eliminating any risk of damage.

In addition, photovoltaic panels can even play a protective role, since they reduce direct exposure of the rain, hail and UV rays, thus prolonging the duration of the life of the materials.

If the installation is carried out by an authorized company, there is no risk that the panels influence the integrity of the roof. Therefore, it is important to choose an expert installer, use quality materials and guarantee a safe and sustainable system.
