Solar panels: What to pay attention to when choosing?

When choosing solar panels, it is crucial to consider panel type, efficiency, and long-term adaptability to ensure optimal energy performance.


In today's global environment, where awareness of environmental issues is steadily rising, the search for sustainable energy sources is exceptionally important. The trend of solar energy aligns with the increasing demand for cleaner and more environmentally friendly alternatives.

In this context, solar energy systems have emerged as a crucial and ubiquitous choice for generating electricity from renewable sources. The ability of solar panels to convert sunlight into usable electrical energy not only reduces dependence on fossil fuels but also creates long-term benefits for the environment and financial savings.

Solar panels have become the preferred choice for reducing electricity bills, both for households and companies seeking sustainable energy solutions. However, selecting the right solar panels tailored to your specific needs requires an in-depth analysis of several key factors.

It is essential to collaborate with experts who can provide personalized advice and solutions to ensure that your solar power plant delivers the best results and long-term economic benefits.

Factors influencing the choice of solar panels:

Type of solar panel

When selecting solar panels, understanding the different types and their characteristics is crucial to making the best choice for your needs. Solar panels can be monocrystalline or polycrystalline.

Monocrystalline panels are recognizable by their darker color and rounded corners, resulting from their production method, which reduces material waste. With higher efficiency in converting sunlight into electrical energy, monocrystalline panels are an excellent choice for limited installation space.

On the other hand, polycrystalline panels have a light blue color and rectangular cells, produced more cost-effectively and efficiently, often resulting in lower prices.

Solar panel efficiency

The efficiency of solar panels quantifies their ability to convert sunlight into electrical energy. Higher panel efficiency allows for the generation of more energy on a smaller surface area, especially beneficial in cases with limited installation space.

It's important to note that while higher-efficiency solar panels often come with a higher initial cost, they can lead to significant long-term savings on electricity costs.


The warranty of solar panels plays a crucial role in assessing their quality and durability. Reputable solar equipment manufacturers often provide warranties that extend from 20 to 25 years. However, it is crucial to carefully analyze the warranty terms to fully understand what is covered and the procedures in case of servicing or panel replacement.

Location and orientation of solar panels

The location and roof orientation of your home play a crucial role in solar panel efficiency. Ideally, solar panels should be south-facing to capture the most sunlight during the day. While in some cases, east and west installations are considered, their energy production is not on par with south-facing panels.

Solar panels are never installed on the north side due to the lack of sunlight. Adjusting the tilt angle of panels, if possible, can significantly improve energy absorption.

Roof material

The choice of roofing material significantly impacts solar panel installation. The type of material determines not only the quantity but also the position of solar panels. Durable metal roofing is the most suitable choice for solar installations due to its ease of panel installation. In contrast, delicate roofing materials like terracotta tiles are prone to cracking, making solar panel installation on such roofs challenging.

Therefore, carefully selecting roofing material is essential to ensure a successful and efficient solar panel installation.

Installation and cost

The range of costs for solar panel installation can vary depending on factors such as geographic location, the size of the solar system, and the complexity of the installation. Ensuring the proper installation and maximum efficiency of this system is crucial. Therefore, engaging experts with extensive experience in solar installations is crucial.

Properly placing solar panels on the roof requires a specially trained and skilled installation team capable of efficiently carrying out and overseeing the implementation of solar solutions of varying levels of complexity.

Maintenance of solar panels

Solar panels require minimal maintenance, but cleaning them from dust and dirt is essential to maintain their efficiency. Solar panels should be cleaned several times a year, and it's important to consider how easily maintenance can be performed on the selected panels.

Duplico Solar power plants

Choosing the optimal solar power plant requires research and careful consideration of a range of key factors. Striking the right balance between economic feasibility, energy efficiency, and durability becomes incredibly important to achieve excellent results aligned with the unique energy needs of your project.

It is advisable to seek advice from experts to ensure that the selected solar panels best suit your individual requirements.

Key is to achieve a balance between cost, performance, and longevity to realize excellent results tailored to your energy needs.

The solar calculator is the first step towards a solar power plant. When you enter basic information about your electricity consumption and provide a brief description of the property, you will receive all the necessary information via email. This tool provides you with a personalized analysis that enables you to make informed decisions about the implementation of solar panels and effectively plan your energy transition.

It's important to emphasize that the informative calculation from the solar calculator represents an experiential estimate. The final price will be accurately provided after the creation of a commercial and technical offer.

Through this approach, we ensure transparency and accuracy, allowing you to make informed decisions about your investment in solar energy.
