Solar panels

Solar panel: basic principles

The solar panels are devices that transform the sun's energy into electricity that can be used to charge your devices or power appliances, among other things. The photovoltaic panels capture direct current (DC) and the solar panel inverter converts it into alternating current (AC).

The electricity production through solar panels is possible due to the materials from which a solar panel is made. Over time, these solar panel materials have evolved and now photovoltaic panels have greater efficiency and energy production capacity. In addition, as technology evolves, the lifetime of self-consumption solar panels increases and the price of solar panels becomes more competitive and affordable.

The price of solar panels has dropped considerably in recent years. Research and advances in photovoltaic solar energy has allowed the fact that buying photovoltaic solar panels has become democratised.

The use of solar energy has become widespread in the population in the last ten years. The research and development of solar panels has been continuous to advance their efficiency. There has also been research into the manufacture of transparent solar panels, flexible solar panels, portable solar panels,... Buying solar panels has become a simple task due to the variety of models and manufacturers. If you need solar panels for your home check out our website FVComponents.com and you will find solar panels at competitive prices.

It is quite common to use solar panels in: single-family homes, industries, campers, boats, caravans,... and even for pumping water. There are also self-installable solar panels. Due to all this progress, the photovoltaic solar panels can be adapted to each type of installation by size (there are even balcony solar panels), types of photovoltaic solar panels, voltage,...

The improvement in the performance of photovoltaic solar panels and a greater supply in the price of solar panels, and coupled with the social and economic context that we live right now has meant that the sale of photovoltaic solar panels in Spain has grown exponentially in recent years. In the following text we will explain the process of how to buy solar panels, the price of solar panels and their utilities, and much more. Continue reading.

Price of solar panels

The solar panels price depends directly on the characteristics of the types of solar panels. That is to say, the solar panels prices can go in one direction or another depending on the brand, the technology used, the quality of the materials, the voltage (V), the power (W),... The solar panel price is something very important in a photovoltaic solar panel system, an installation can have as many photovoltaic solar panels as needed according to the consumption of the house.

The price of photovoltaic panels varies depending on whether it is the price of the solar panel and is purchased by units or by pallet of photovoltaic panels. Knowing all this about the price you can choose how many solar panels I need for a house.

At FVComponents.com we have a wide range of solar panels, solar panel kit, solar panels for house, solar panel for van... The price depends on whether it is a monocrystalline solar panel or polycrystalline photovoltaic cells. The solar panel price will also depend on whether it has PERC technology, if it is a bifacial solar panel, if you buy a solar panel kit instead of the equipment separately.

How much does a solar panel cost?

The price of a 12V solar panel is between €25 and €110.

The price of solar panels has a wide range and will depend largely on their voltage. It is not the same to buy photovoltaic solar panels of 12V than another voltage. We explain their differences.

• Photovoltaic panels 12V: These photovoltaic solar panels are the lowest priced on the market as they are smaller in size and power. The approximate price of solar panels can range from €25 to €110. Their powers range from 30W to 200W.
• Photovoltaic panels 24V: These types of panels have a higher price than 12V panels because their size is medium/large. They also have higher power ratings, typically ranging from 200W to 550W.

How much does a solar panel cost?

The price of a 24V solar panel is between 150€ and 200€.

It should be remembered that the price of a solar panel varies depending on the manufacturer, efficiency, materials or energy capacity. If you want to know the price of solar panels, you must take into account the type of solar panel and its technology.

• Polycrystalline solar panel: This type of photovoltaic solar panels are made of several silicon photovoltaic cells joined together. This solar panel is less expensive as its performance is lower and its materials are of poorer quality.
• Monocrystalline solar panel: These photovoltaic solar panels are made from a single silicon crystal cell. Their manufacturing process is more complicated and they are therefore more expensive, but they are more efficient.

The price of installing solar panels and also the purchase price is getting lower and lower, but you can't expect to get free solar panels from the government.

To the question of how much it costs to install solar panels must be added the price of other technologies that can increase it.

• PERC technology: This technology is used in some photovoltaic solar panels. They have a reflective layer on the back that increases the efficiency of the solar panels.
• Half-Cell Technology: This technology uses photovoltaic cells cut in half, so each half of the photovoltaic panels gives 50% of capacity to each cell.

All these technological advances influence the price of solar panels, although there are also other aspects that affect the cost of photovoltaic panels, which we explain below.

Solar panels price: Which one should I choose for my house?

If you are wondering "how much is a solar panel worth", it depends; the price of solar panels has decreased in the last decade due to the increase in demand in the sector and because of technological progress. On the FVComponentes.com website you can find a wide range of prices to suit all budgets and needs.

There is one factor that undoubtedly affects the price of solar panels, the power. For example, you have to take into account how many solar panels you need to generate 5 kW, the more power you need, the more panels you need and/or the bigger the panels. As the power increases, so does the price of solar panels. What other elements also influence the price of solar panels? The technology used in their manufacture, the use or not of monocrystalline silicon and the other is the PERC technology, all this influences the solar panels price.

The use of a single piece of silicon (monocrystalline) means an increase in the price of solar panels, as it is much more efficient than a polycrystalline solar panel. The use of PERC technology in solar panels is implemented so that the efficiency does not drop with the reflection of radiation. As mentioned above, this increases the price of solar panels.

A solar panel without these technologies would have almost no efficiency, so they are implemented in most of the models that we have in FVComponentes.com. Therefore, their use directly affects the price of photovoltaic solar panels.

You can also buy solar panels on pallets, i.e. in bulk. The price of solar panels on pallets rises to €3,000, but the pallets contain 31 or 36 panels, so you end up making considerable savings on each pallet.

You have already seen all the price possibilities of solar panels, both individually and in pallet. In short, at FVComponentes.com you can find a wide variety of photovoltaic panels and always at the best price.

Before carrying out a photovoltaic project, there are a few points to consider in order to achieve the maximum yield and the desired objective:

Placement of the solar panels. The orientation of the photovoltaic solar panels must be taken into account. They should be installed facing south and at a suitable angle depending on the latitude. In order to get the most out of the photovoltaic panels, shadows should be avoided. If there are shadows, the yield is greatly reduced. If the installation is made up of panels in series, when affecting a photovoltaic panel it ends up affecting all the solar panels connected in series, so there should not be any shadows on the photovoltaic installation. You can take a look at this website solar panel tilt calculator.

Structures. Each installation of photovoltaic panels requires a different type of structure depending on where they are going to be installed: flat roofs, tiled roofs, metal roofs, etc. The panels are heavy and large, so it is very important to choose the right structure to avoid future problems.

Position. The panels are generally placed in a fixed position that does not change. When installed outdoors, dust, leaves and dirt are deposited and this reduces the efficiency of the photovoltaic cells and if you are wondering how to clean solar panels; they have an external glass, so in the same way as conventional glass is cleaned. The system must be checked periodically and more frequently if we are in rural or maritime areas.

Component warranty. The components of solar panel systems are characterised by a long service life. A photovoltaic solar panel can have a service life of around 40 years and comes with a manufacturer's warranty of 15 years or 25 years.

At FVComponents.com you can buy photovoltaic solar panels along with the other necessary components to make a correct photovoltaic installation at a good price, here you have our network connection kit.

Best photovoltaic panels - What types of solar panels are there?

Solar panels are composed of photovoltaic cells capable of producing electricity from the solar radiation that falls on them. They are classified according to the type of cell:

Monocrystalline: made of single-crystal silicon photovoltaic cells. They are recognisable by the shape of the photovoltaic cells, circular or octagonal as they are made from cut-out circular photovoltaic cells. Currently, they are the solar panels The most efficient and most widely used. The other technologies are more economical, but have worse performance and also worse aesthetics for integration into the roof of your home.

Polycrystalline: panels consisting of panels with photovoltaic cells made of multiple crystallised silicon particles. The cells of these photovoltaic panels are usually rectangular in shape and have an irregular bluish hue.

Amorphous: also called end-layer and composed of uncrystallised silicon. They are photovoltaic panels with very low performance and their use is limited to small objects such as calculators, chargers...

Depending on the type of cell chosen, the performance will vary.

To know which photovoltaic panel produces the best performance in the installation we must take into account factors such as the size of the surface where the panels are going to be placed, the power we want the installation to generate, the consumption... In FVComponentes.com we only have monocrystalline solar panels, as they are the most efficient and have the best performance.

How solar panels work

As explained above, solar panels are made up of photovoltaic cells that are responsible for converting the energy from sunlight into electrical energy. The silicon collects the photons of sunlight and transforms them into direct current. This current must pass through the solar panel inverter so that it can transform it into alternating current, which is needed for the electrical appliances in the house.

This is possible because photovoltaic panels are made of semiconductor materials, such as silicon. When sunlight strikes a cell of the same photovoltaic cells, the electrons in the semiconductor material are excited and released from their atoms. These electrons then move through the material and thus generate an electric current. With this technology becoming more and more developed, it allows the installation of solar panels to be amortised very quickly and thus justifies the investment.

The amount of electrical energy generated by photovoltaic panels depends on several factors, such as the intensity of sunlight, the ambient temperature and the quality of the materials used in the manufacture of the photovoltaic cells. It is also important to remember to install the PV modules in a location that receives an adequate amount of sunlight throughout the year to maximise their efficiency and energy production.
