Solar photovoltaic panels
What are solar photovoltaic panels?
Photovoltaic panels, also known as photovoltaic modules, photovoltaic solar panels or solar current collectors, are devices designed to convert sunlight into electricity. At their core are solar cells, usually made of semiconductor materials such as silicon. These cells, arranged in a grid pattern on the surface of the panel, use the photovoltaic effect to generate electricity when exposed to sunlight. The process involves absorbing photons from sunlight, which excites electrons in the cells, causing them to flow and generate a direct current.
At a time when concerns about climate change and the relentless search for sustainable energy sources are on the rise, solar photovoltaic panels have emerged as a beacon of hope and innovation. They are transforming the way we harness solar energy, offering a clean and renewable solution to the ever-increasing demand for electricity.
At its core, a solar panel is a device designed to convert sunlight into electricity through a process known as the photovoltaic effect. All current solar panels consist of multiple solar cells made of semiconductor materials, most commonly silicon. The cells are arranged on a panel to form a lattice structure. When sunlight hits these cells, it excites the electrons in them, causing them to flow like an electric current. This direct current (DC) is then transformed into alternating current (AC) using an inverter, making it compatible with the electrical grid and ready for use in homes, businesses and industries.
One of the most idealized aspects of solar PV panels is their environmental impact, or rather lack thereof. Unlike fossil fuels, which emit harmful greenhouse gases when burned, solar panels generate electricity without any emissions or pollution. This makes quality solar panels an essential tool for reducing your carbon footprint and fighting climate change.
Photovoltaic panels - advantages
Solar PV panels have quickly gained popularity as a clean and sustainable source of electricity, and their many benefits extend beyond environmental benefits. Here are some of them:
- Clean and renewable energy – Perhaps the most significant advantage of solar photovoltaic panels is their ability to generate electricity without emitting harmful greenhouse gases or pollutants. They harness the power of the sun, making them a crucial tool in reducing carbon emissions and fighting climate change;
- Lower electricity bills – By generating their own electricity, solar PV system owners can reduce their dependence on grid power, resulting in long-term savings. This is just one of the reasons many people make the investment in solar panels.
- Energy independence – By generating electricity on-site, homes and businesses are less susceptible to power outages caused by grid failure or extreme weather events. This additional independence can be particularly valuable in regions prone to such situations.
- Increased property value - Homes and commercial properties equipped with solar panels tend to have higher resale values.
- Environmental benefits - In addition to reducing carbon emissions, solar panels reduce demand for finite fossil fuels, conserving valuable natural resources.

Photovoltaics for the home
Today, solar panels for the home are considered a transformative solution to meeting our energy needs as well as our environmental goals. All home solar is a big step towards a sustainable lifestyle and a greener future.
The efficiency of a solar power system is determined by the quality and manufacturing technology of the cells that make up the panel. It expresses the rate at which sunlight is converted into electrical energy, or in other words, how much of the incoming solar energy is converted into electrical energy.
One of the most preferred for the home is solar panels up to 500W - this is because they provide the most optimal price-quality ratio. However, this is not the only thing that determines the efficiency of a solar home system. It also depends on the orientation and inclination of the photovoltaic panels, their cleaning and maintenance, the percentage of shading, as well as the latitude.
Some solar home systems also operate on batteries. Such systems can both be connected to the power distribution network and work autonomously. Battery capacities are commonly referred to as solar batteries or solar energy storage systems and play a crucial role in increasing the efficiency and reliability of solar energy systems. Photovoltaic batteries are designed to store excess electricity generated by solar panels during the day for later use, usually at night or when there is insufficient sunlight.
Solar Panel Program
Interest around innovative solar power panels has grown significantly over the past few years. Their indisputable advantages and the ability to reduce the energy costs of households and businesses make them highly desirable by more and more people today. It is because of the high interest that solar panel programs exist today, enabling thousands of people to finance their business and home solar project.
Subsidies for solar panels and other equipment can be obtained by any person or company who applies and meets the conditions of the programs. Application for solar panels by program is made at the Ministry of Innovation and Growth, where current programs and results can also be tracked.
If you too are planning to apply for a solar panel program or have already received funding, we can help you implement and finalize your project. Trust Global-Test for everything from the initial analysis, through the determination of the appropriate energy-saving measures to their implementation. We carry out every single project "turnkey", which provides you with maximum convenience.
Delivery and installation of photovoltaic panels
The process of supplying and installing photovoltaic panels usually involves several steps to ensure a successful and safe installation process. Here's what you can expect in a nutshell.
Prior to delivery and installation, an analysis will be conducted to evaluate your energy needs, the condition of the intended installation site, shading, and other factors to determine the best size and configuration of a solar system for your home. or business.
Detailed plans for your system will then be created. This includes determining the most optimal angle of the photovoltaic panel, the type of installation, as well as its most suitable location - on the roof or mounted on the ground.
After designing and issuing a permit, the installation of photovoltaics itself remains. The solar installation company will provide the necessary equipment, including the structure for mounting the photovoltaic panels, wiring and other components. Photovoltaic panels and other equipment will be delivered to your property in advance on the appointed installation day. Delivery will be coordinated upon arrival of the installation team.
Once the installation is complete, it's time to start enjoying the benefits of your system, including the biggest one – lower energy bills.
Regular maintenance, such as cleaning the panels and checking for any problems, is essential to ensure the long-term efficiency and reliability of your solar panels. Global-Test offers a range of services for regular maintenance of your photovoltaic plant, including professional cleaning of the panels.
Price of photovoltaic panels
In addition to energy savings and reduced environmental impact, photovoltaics offer financial benefits, increased property values and a sense of energy independence. And as technology continues to advance and incentives encourage solar adoption, residential and commercial solar panels are expected to grow in appeal, making them a wise choice for property owners looking to embrace clean energy and reduce their footprint on the environment.
That is why today more and more people want to know how much it costs to install photovoltaic panels. The truth is that it depends on a number of factors – the size, the power, the subcontractors you will hire, and many others.
