Difference between solar and photovoltaic panels
Solar panels and photovoltaic panels: although both are devices that use the sun’s energy, there are significant differences between the two technologies. In this article, we will explore the fundamental differences between solar and photovoltaic panels, helping you to better understand the areas of application.
The main differences between solar and photovoltaic panels
Solar panels
A solar panel, also known as a solar thermal collector, is a device designed to capture solar energy and convert it into usable heat. This heat can be used in different applications, making solar panels a versatile solution for using solar energy. In addition to domestic water heating or home heating, solar panels can be used for other purposes, such as air heating (radiant panel heating systems) or drying agricultural products..
In the industrial sector, solar panels can be used for heating industrial processes or for producing steam for commercial purposes. A practical example of the application of solar panels is their use in swimming pool heating systems. By installing solar thermal panels on your roof or near your pool, you can heat your pool water using solar energy, thus reducing the energy costs associated with using traditional heating systems. Furthermore, solar panels can be integrated into home heating systems, helping to reduce environmental impact and energy costs.
In summary, solar panels are versatile devices that offer a sustainable solution for harnessing solar energy for heating water and business or residential facilities, as well as for a wide variety of other industrial and commercial applications. Their ability to directly convert solar energy into heat makes them a sustainable and renewable alternative to traditional energy sources.
Photovoltaic panels
Photovoltaic panels, or photovoltaic modules, represent one of the most widespread and promising technologies in the field of solar energy. These panels exploit the phenomenon of the photovoltaic effect to directly convert solar energy into electricity. Their main components are photovoltaic cells, generally made with silicon semiconductors, which act as power generators when exposed to sunlight.
A distinctive feature of photovoltaic panels is their ability to generate direct electric current, which must be converted to alternating current for domestic or commercial use. This occurs through the use of a device called an inverter, which converts the direct current produced by the modules into alternating current compatible with traditional electrical systems. This feature makes them extremely versatile and suitable for powering a wide range of electrical equipment, thus generating clear savings on bill costs.
A practical example of the application of photovoltaic panels is their installation on company roofs to generate electricity for industrial use. The energy produced by the panels can be used to power electrical appliances, lights, electronic devices and other complex machinery used in the industrial sector (cold rooms, production lines, etc.). Furthermore, photovoltaic systems can be sized according to the energy needs of the specific company and can be integrated with storage systems to store excess energy for night-time use or in the event of network interruptions in order to make companies energy-intensive ever closer to energy autarky.
In addition to the above, photovoltaic panels find application in a wide range of contexts: they can be used to power public lighting systems, road signs, charging stations for electric vehicles and much more. Their versatility, combined with their ability to generate clean, renewable energy, makes them an increasingly popular choice for reducing environmental impact and energy costs.
In conclusion, photovoltaic panels represent an effective and efficient solution for generating electricity from renewable sources. Their ability to directly convert solar energy into electricity makes them an attractive choice for anyone looking to reduce dependence on traditional energy sources and adopt more sustainable energy production practices.
Possible applications in the corporate or domestic context
Solar technology offers a wide range of applications for both the business and domestic sectors, allowing solar energy to be exploited efficiently and sustainably. Here are some possible applications of solar and photovoltaic panels in both contexts, and the benefits and opportunities offered by these energy solutions.
Solar panels
Among the most widespread applications is water heating: solar panels are widely used to heat water for domestic or industrial use. This can include water heating for swimming pools, showers, laundry facilities and other water needs.
Photovoltaic panels
This technology offers a wide range of applications, for example here are some:
- Electricity Generation: Photovoltaic panels are used to generate electricity from renewable sources. They can be installed on building roofs, land or other surfaces exposed to the sun to produce electricity for domestic, commercial or industrial use.
- Connection to the electricity grid: the energy generated by photovoltaic systems can be transferred to the national electricity grid, generating economic valorisation of the same. This allows users to obtain additional income from solar energy production and contribute to reducing environmental impact.
- Energy storage systems: Photovoltaic panels can be integrated with energy storage systems, such as batteries, to store the energy produced for future use. This allows users to use solar energy even during night hours or in the event of grid outages.
- Other Applications: Photovoltaic panels can be used to power street lighting systems, traffic signs, electric vehicle charging stations and other electronic devices. Their versatility makes them suitable for a wide range of applications in both home and business environments.
Which technology to choose?
The two technologies described above respond to different consumption needs, which can however coexist in the same context. It is therefore useful to ask yourself what the most suitable solution might be for your structure, be it a home or a factory. To obtain a more precise indication, it is advisable to carry out a specific consumption analysis, relying on expert technical personnel who can offer support in all analysis and design phases.
The application of the two technologies generates significant advantages in terms of sustainability and energy saving, if well integrated with the customer’s energy needs. If you would like more information or personalized advice regarding your facility, contact the Suthenergy team.
