Rating of the best solar panels in 2024

The sun is an inexhaustible source of clean energy. For a long time, mankind perceived the sun as a source of heat and light, without thinking about its fuller use for its own purposes. With the development of new technologies, it became possible not only to use the sun's energy more fully, but also to accumulate it. Initially, the use of solar energy technologies was limited by the high cost of components and low productivity. Now, with the increase in the efficiency of solar systems and their gradual cost reduction, it has become possible to use this energy source for household purposes on an individual basis.

Everyone who wishes, having weighed all the pros and cons, can switch to the use of ecologically clean energy of the Sun and stop depending on the centralized power supply network. This is especially true when the country house is located far from power lines. In addition, solar systems can be used as an additional (backup) energy source, protecting yourself from power outages.

Panels differ in production technology, quality, method of use, and many other parameters. Let's try to understand this variety of proposed solar modules and highlight the best of them.

Types of solar panels

A solar panel is a combination of photovoltaic cells that convert the sun's energy into electric current.

According to the technology for the production of solar cells, all solar panels are divided into two large groups: silicon and film. Their types and features will be discussed in the table below.

Group	A type	Features:	Efficiency,%
Silicon	Monocrystalline (mono-Si)	They are one silicon crystal. They are square with rounded corners. Color gray or black to blue (with antireflection coating). Best converts direct solar radiation. Most expensive.	from 15 to 22
Silicon	Polycrystalline (poly-Si)	A block of silicon crystals connected to each other. They are square. Silver gray or blue (with antireflection coating). The absorption capacity of direct solar radiation is worse. Best used to generate energy from scattered radiation. Cheaper than single crystals.	12 to 18
Silicon, film	Amorphous	They occupy an intermediate position, because made of silicon, but in the form of a film. They are the deposition of a silicon semiconductor on a base. Convenient to use. Within six months or a year, they burn out in the sun, and therefore, their power decreases.	from 5 to 6
Film	Based on cadmium telluride	They look like a film that is applied to glass. Mirror dark green or black. Most often used in space and in Earth orbit. Toxic: they release harmful cadmium. Difficult disposal.	from 10 to 12
Film	Based on CIGS (copper indium selenide)	They have the form of a film in which copper-indium selenide is used as a semiconductor. Color from dark gray to black. Corroded.	from 15 to 20
Film	Polymer	They look like a very thin film. Cheap in production, do not emit harmful substances.	from 5 to 6

Now, focusing on the types of solar panels, we will consider in which areas of human life each of them is used.

Scope of solar panels

Stationary panels

Solar panels can be used both in stationary conditions and be portable.

Fixed modules are used in the following areas:

• at solar power plants;
• in autonomous, standby or hybrid power plants for a home or summer cottage;
• for space heating and water heating (solar collector);
• in autonomous street lighting systems;
• to power billboards;
• in navigation and alarm systems;
• in pumping stations, etc.

Considering stationary solar power plants, let us dwell in more detail on those that are used to supply power to the house. To provide a home with electricity using the energy of the Sun, you will need the following components:

• solar modules;
• battery (to accumulate unused energy);
• voltage controller (increases battery life, but is not required for installation);
• inverter (converts the direct current of the battery into the required alternating current for electrical appliances).

Home solar power plants in relation to centralized power supply can be:

• autonomous.

Autonomous, i.e. independent of other power sources, solar power plants are used where it is impossible for certain reasons (considerable remoteness from settlements) to connect to the general power grid. Their use is advisable in the southern regions, where daylight hours are longer and there are a large number of clear days. In any case, it is desirable to duplicate it with a generator running on combustible fuel. The main advantages of an autonomous station are its environmental friendliness, noiselessness, and minimal maintenance during operation. Minus - at night or on cloudy days, electricity will not be generated. In addition, for their work, the above-named components are needed, which make the autonomous system quite expensive.

• backup.

Reserve, or network, power plants are installed where there is a connection to the central electric network. It is used as an additional source of electricity. The backup solar power plant starts its work in the event of a power outage from the network. Advantages - noiselessness, reliability, the ability to mount on the roof or facade of a building. Another plus is the lack of a battery, controller and inverter, which significantly reduces the cost of the system.

• hybrid.

In fact, it is an autonomous station connected to the electrical network. The energy received from the Sun is used in the first place; in case of its shortage, electricity is supplied from the centralized power supply. Allows you to significantly save on payments for consumed electricity.

Mobile modules

Mobile devices for converting solar energy into electric current can be used:

• for charging mobile phones and other mobile devices;
• for powering radios during hiking, fishing;
• for powering navigation systems during expeditions;
• for lighting in the dark during hikes.

Portable batteries have become an indispensable accessory for out-of-town travel enthusiasts and tourists traveling in wild places where there is no electricity. Since modern life, even on a desert island or in the mountains, is impossible without various gadgets, they are recharged from chargers that convert solar energy. Portable solar cells are most often produced on the basis of monocrystalline silicon. They differ in size, shape, power. Compact batteries with low power can fit in a pocket, while large and powerful batteries can be installed on the roof of a car. In addition, they are equipped with all kinds of adapters for connecting various equipment.

What to look for when choosing solar panels

Due to the fact that the use of solar energy for domestic purposes has not yet become commonplace, and the choice of solar panels causes certain difficulties, we offer a list of the most important parameters. So, when buying such a module, you should pay attention to the following points:

• manufacturer.

It is important to pay attention to how long a given manufacturer has been on the market for this product, and what is its production volume. The longer a manufacturer has been in the industry, the more you can trust him.

• area of ​​use.

For what purposes the received energy will be used: for charging small equipment, for power supply of large electrical appliances, for lighting or for a full power supply of the house. The choice of the output voltage and power of the panels depends on the purpose for which the solar module is purchased.

• voltage.

For small electrical appliances, 9 V is enough, for charging smartphones and laptops - 12-19 V, and for providing the entire power system at home - 24 V or more.

• power.

This parameter is calculated on the basis of the average daily energy consumption (the sum of the energy consumed by all equipment per day). The power of solar panels should cover consumption with some margin.

• quality of photovoltaic cells.

There are 4 quality categories of photovoltaic cells that make up a solar panel: Grad A, Grad B, Grad C, Grad D. Naturally, the first category is best - Grad A. Modules of this quality category do not have chips and microcracks, are uniform in color and structure, have the highest efficiency and are practically not subject to degradation.

• life time.

The lifespan of solar panels ranges from 10 to 20 years. Of course, the duration of the full operation of such a power system depends on the quality of the batteries and the correctness of their installation.

• additional technical parameters.

The most important are efficiency, tolerance (power tolerance), temperature coefficient (influence of temperature on battery performance).

Having understood the main technical characteristics, we offer you a ranking of the best solar panels in 2024.

Conclusion

The sun is not only a source of light and heat, but also a source of inexhaustible energy. If earlier the alternative energy of the Sun was used most of all in the space and industrial sectors, now it has rapidly entered the domestic sphere. Solar water heaters, photovoltaic lighting fixtures, photovoltaic gadget chargers are all real examples of how the sun is used in everyday life.

If initially the advantages of using solar energy were attributed only to its environmental friendliness and inexhaustibility, now the list of advantages has expanded. So, the advantages of solar energy and its use:

• independence from third-party power systems;
• the constancy of the supply of electric current (no voltage surges);
• long service life (20-30 years depending on quality);
• independence from the season of the year (polycrystalline panels catch scattered radiation even in rainy weather);
• minimum service (cleaning the front of the panel from dust).

An item such as efficiency is difficult to attribute specifically to pluses or minuses. The fact is that the full provision of a country house with electricity due to the installation of solar panels requires a one-time large investment (this can, in a sense, be a minus). But in the long run, all costs are more than paid off (this is a plus). It is important to calculate everything correctly in advance and find the best option for a specific situation.

The only significant drawback to solar power systems is that they don't work at night. This requires the installation of energy storage devices. We hope our tips and best solar panels reviewed will help you get started using the green energy of the sun.
