SOLAR PANELS

Solar panels: What are they?

Solar panels, made with materials that transform solar radiation into electricity, are devices that capture the sun's energy. Photovoltaic solar energy has a significant impact on the provision of electrical energy, the country's economy and the environment.

The generation of electricity through solar panels is achieved thanks to the materials used in the manufacture of the solar panels. Over time, these materials have evolved, and currently, the market offers photovoltaic panels with greater durability, outstanding reliability and more competitive prices to purchase photovoltaic solar panels.

Photovoltaic solar panels are made up of photovoltaic cells that are connected in series and parallel to achieve the appropriate voltage and intensity values. For this reason, 12V photovoltaic solar panels consist of 36 photovoltaic cells, 24V solar panels have 72 cells, and so-called grid-connected photovoltaic solar panels have 60 photovoltaic cells. In general, the number of photovoltaic cells affects the price of solar panels.

The varied offer and different prices of solar panels allow solar kits to be accessible to homes that opt ​​for renewable energies and want to reduce their electricity bills or that do not have access to the electrical grid (isolated) when purchasing photovoltaic solar panels.

Photovoltaic panels are commonly used in single-family homes, caravans, boats and even for water pumping systems. Over the years, the technology of photovoltaic solar panels has improved, increasing their efficiency and making them more profitable, with the aim of achieving photovoltaic self-consumption.

The increase in the performance of photovoltaic solar panels and the greater availability of price options, together with the current social and economic context, have driven the exponential growth in the sale of photovoltaic solar panels in Spain in recent years.

Photovoltaic panels are more profitable when self-consumption represents more than 60% of production, that is, when the energy generated by photovoltaic solar panels covers 60% or more of electricity consumption.

⇒ If you are in a location without access to the electrical grid and need electricity, you can visit our category of isolated photovoltaic solar panel kits. These kits include solar batteries in their components, which guarantees complete energy autonomy.

⇒ On the other hand, if you need to install photovoltaic panels in your home and you have access to the electrical grid, we recommend exploring our grid-connected solar panel kits. These kits are highly cost-effective as they contribute significantly to reducing your electricity bill.

⇒ If you want to minimize your dependence on the electrical grid as much as possible, we invite you to explore our hybrid photovoltaic solar panel kit.

When considering the purchase of photovoltaic solar panels, it is important to take into account the following aspects:

❶ Define your objectives or needs and understand how photovoltaic panels can help you achieve them.

❷ Establish precisely the level of consumption you want to cover to determine the number of photovoltaic panels needed.

❸ Properly size the installation of photovoltaic panels.

❹ Consider the future and how you can further optimize the profitability of photovoltaic panels.

❺ Know in detail the ideal location, orientation and inclination for solar panels.

Taking these aspects into account, you will be able to make informed decisions and reduce the cost of solar panels.

They should face south and have an appropriate inclination depending on the latitude to maximize efficiency. The presence of shadows also significantly affects energy production, so it is essential to avoid them throughout the photovoltaic installation.

- Suitable structures: Each solar panel installation requires specific structures depending on the location, such as flat roofs, tile roofs or metal roofs. Since the panels have considerable dimensions and weight, it is essential to choose the appropriate structure to avoid future problems.

- Regular maintenance: Solar panels, being outdoors, accumulate dust, leaves and dirt that reduce their productivity. Periodic maintenance is recommended, especially in rural or coastal areas.

- Component warranty: The components of solar installations have a long useful life. Photovoltaic solar panels, for example, can last up to 40 years and usually come with 25-year warranties from the manufacturer. This ensures the long-term reliability of your solar energy investment.

The Best Photovoltaic Panels and Types of Solar Panels

Solar panels, as we mentioned above, are made up of photovoltaic cells that convert solar radiation into electricity. These solar panels can be classified according to the type of cell used:

1. Monocrystalline:These panels are made up of photovoltaic cells made of a single crystal of silicon. They are characterized by the shape of their cells, which are circular or octagonal from cut circular cells. Currently, they are the most used solar panels and offer the best performance. Although they are a little more expensive, they are ideal to integrate into the roof of your home due to their better aesthetics.

2. Polycrystalline:Polycrystalline panels are made up of photovoltaic cells with multiple crystallized silicon particles. These cells usually have a rectangular shape and a more bluish tone with a more irregular coloration compared to monocrystalline cells. Although they are cheaper, their performance is slightly lower.

3. Amorphous:Also known as thin film panels, they are made of non-crystallized silicon. They are low-performance panels and are mainly used in small devices, such as calculators and chargers.

The choice of the type of solar panel will depend on factors such as the size of the available surface, the desired power for the installation and energy consumption. At Varisolar, we primarily offer monocrystalline solar panels, but we may also have polycrystalline models available.

How Photovoltaic Panels Work

Photovoltaic panels work by using semiconductor materials, such as silicon. When sunlight hits photovoltaic cells, the photons in the light excite the electrons in the semiconductor material, freeing them from their atoms. These electrons, now in motion, generate an electric current.

However, this generated current is continuous (direct current or DC), and most electrical devices in homes and businesses use alternating current (alternating current or AC). Therefore, an inverter is necessary to transform direct current into alternating current, which is the form of electricity commonly used in our homes and businesses.

The amount of electrical energy that can be generated with solar panels depends on several factors, including the intensity of sunlight, the ambient temperature and the quality of the materials used in the construction of the photovoltaic cells. It is also essential that solar panels be located in a location that receives an adequate amount of sunlight throughout the year to maximize their efficiency and energy production.
