What is the yield of a solar panel ?
The yield of a solar panel is a measure of its ability to Sun light in Usable electricity. THE basic yield a solar panel is determined by the electricity production Photovoltaic cells, which is in turn influenced by the composition of the cells, the electrical configuration, the surrounding components, etc. All the solar light that reaches a photovoltaic cell is not converted into electricity. In reality, the major part East lost.
What is the best performance of a solar panel ? Thanks to the many advances in photovoltaic technology in recent years, the average panel conversion yield has increased from 15 % to more than 20 %. This percentage may seem low, but it represents a significant advance compared to the old models of solar panels.
Improving this conversion yield is a key goal of research and development and helps make photovoltaic technologies more competitive Compared to those using more conventional energy sources.
Its ultimate objective is to guarantee the highest profitability of the solar installation.
Calculation of the power of a solar panel by m²
To obtain an approximation of the yield of a solar panel, it is possible to apply the following formula:
Yield of a solar panel = power (WC) / (area (m2) × 1000).
For example, to obtain the yield of a solar panel of 100 toilets on an area of 0.5 m², The calculation is: 100 WC / (0.5 × 1000) = 20 %. But for a more precise result, it is necessary to take into account the factors affecting the yield of a solar panel.
What are the factors that affect the yield of a solar panel ?
The yield of a solar panel depends on its basic yield, but also on several other factors that must be taken into account even before installation ::
- L’shady ;
- L’rooftop ;
- There temperature ;
- THE Panel type ;
- L’panel orientation ;
- There surface and the roof shape ;
- THE time and thewear.

Tips to optimize the yield of a solar panel
Beyond investing in a High yield solar panel When you want to get the best possible return, you must also seek to optimize this performance afterwards.
Call on a RGE certified installer
Call on a certified installer RGE (recognized guarantor of the environment) Allows you to be advised as best as possible to install its solar panels. Indeed, if the solar panels are not installed correctly, they will not receive the quantity optimal solar light and will therefore produce less electricity.
In addition, using a RGE certified installer allows you to benefit from State aid Compared to the installation of solar panels at home.
The 7 tips by selectra
Here are seven factors that degrade the performance of solar panels, as well as the tips that you can apply to optimize the performance of your panel.
Factors | Advice |
---|---|
Shady | If a panel is shaded, even partially, the production of thesystem set is reduced. There are ways to get around this problem, for example by dividing the network in several channels or using microwilers at the back of the panels. |
Tilt | To obtain the best possible efficiency, solar panels must be tilted from 30 to 35 degrees compared to the horizontal,- an inclination of 5 degrees so that the water can flow. |
Temperature | Photovoltaic solar panels work better at low temperature. A Thermal management appropriate installation could improve bothefficiency and the life of the photovoltaic installation. |
Panel type | Solar panels made up of monocrystallins are the most efficient And require less surface that other panels. It converts almost a quarter of solar energy into electricity with an efficiency that can reach the 25 %. |
Surface and shape | Although it is not always necessary to cover the entire roof of solar panels to cover your needs, it can still be recommended to do so, because it is possible to resell the production surplus at EDF OA Solar at very advantageous. |
Orientation | Solar panels are designed to provide better performance when the sun’s radiation is perpendicular to the panel, that is to say when there is an angle of 90 degrees between the panel and the sun. |
Time and wear | Deterioration reduces the yield of solar panels 2 has 4 % in 15 has 20 years of use. It is possible to slow down deterioration through regular solar panels maintenance. |

Installing solar panels at home allows you to produce your own electricity and achieve considerable savings. However, it is important to know how much electricity they will produce to make the installation as profitable as possible. The yield of a solar panel depends on several factors such as the type of technology used, the orientation or the geographic area. Today, the average yield of solar panels is between 7% and 24%.
What is the yield of a solar panel ?
The yield of a solar panel indicates the ratio between the energy produced and the power of the radiation captured. In fact, solar panels capture the sun’s rays to transform them into electricity, but this conversion causes some losses. Today, The average yield of solar panels is estimated between 7% and 24%.
The yield of a solar panel is therefore the share of real energy that can be consumed in the form of electricity, once the whole transformation process has been completed. For example, If a solar panel has a yield of 10%, this means that 10% of the light captured has really turned into electricity.
The yield of a solar panel varies depending on many factors. The higher it is, the higher the possible savings.

What is the utility of measuring the production of solar panels ?
When talking about solar panels, several measuring units are used. We hear about Watt (W), Watt-Crête (WC) and Watt Hour (WH). What is the difference between the three, what do they measure ?
- THE Watt-Rêce is the unit of power measurement of a solar panel. It is, in fact, the delivery of an electrical power of 1 Watt, under good conditions of sunshine and orientation. The good conditions of sunshine are: sunshine of 1000 watts per square meter and a temperature of 25 ° C. The watt-crew is used in the form of a Kilowatt Crete (KWC) is used to compare the performance of photovoltaic materials as well as Fill in the size of solar equipment.
- THE Watt is the unit of measurement of energy power. Applied to solar panels, it is used, most often in the form of kilowatts, for indicate the energy production of these.
- THE Watt time is the measurement unit used to indicate the amount of enery produced by panels in one hour.. It is the kilowatt hour that is used most of the time.
Solid panel yield: the calculation formula
The yield of a solar panel is expressed as a percentage. It is different from the power of a solar panel, which is expressed in watt-crests and which is the maximum power of electrical production that a panel can deliver.
For Calculate the yield of a solar panel, You have to take into account its definition. The formula to use is as follows:
Yield = electrical power produced / solar power received.
How does the yield of a solar panel vary ?
Several factors must be taken into account to obtain a solar panel high yield. Indeed, the Calculation of the yield of a solar panel depends on many parameters:
- There technology : monocrystalline, polycrystalline or amorphous panels;
- There power solar panels ;
- L’orientation installation;
- L’tilt solar panels ;
- There geographical area, Because the level of sunshine is not the same everywhere in France. This does not mean, however, that only those who live in sunny regions can obtain a good yield;
- There surface Signs ;
- THE Possible shade (trees, posts, buildings nearby, etc.);
- THE yield of other components solar kit (inverter, cables, etc.)).

Recall me
However, it is always interesting to know the right techniques to optimize the performance of a solar panel. For that it is necessary take into account each parameter that vary it.
The level of sunshine
Naturally, the more the accommodation benefits from prolonged sunshine, the higher the yield because the panels use solar energy. However, Solar panels are not only reserved for residents of the south of France, Contrary to popular belief.
They can be profitable everywhere in the territory. Indeed, there are several weather factors which can vary the yield of a solar panel between two homes located in the same region.
Orientation of solar panels
In the same logic as the previous one, The more the panel exposed to the sun, the higher the yield. Which means that the orientation of solar panels is also an essential parameter. In general, It is always in the south that the panels capture the most light throughout the year.
But again, This factor is important but not decisive . If the roof is not south oriented, that does not mean that the installation will not be profitable. Concretely, An installation oriented to the south, respecting a good inclination and a power of 3kwc is profitable in approximately 11 years.
In less good conditions, it would be profitable in around 14 years . There is therefore a minimal difference of 3 years, which is completely negligible knowing that the lifespan of a solar panel reached almost 40 years.
It is therefore completely acceptable to have a west, southwest, east and southeast facing installation . On the other hand, Orientations in the north are not recommended .
The inclination of solar panels
Another parameter to take into account to maximize the yield of a solar panel is its inclination. To produce the maximum energy throughout the year and therefore have a good solar panel yield, The panels must be tilted from 30 to 35 ° compared to the horizontal.
The orientation and inclination of solar panels are important, but it is necessary to reassure yourself because they do not influence the yield of a solar panel in a drastic way .
The influence of temperature
The temperature can vary the yield of a solar panel considerably. The optimal temperature is 25 °. A solar panel undergoing a higher temperature loses up to 0.5% yield per additional degree .
Take the example of a temperature of 40 °, 15 ° more than the ideal temperature, and a solar panel of a yield of 24%. During this period at high temperatures, the yield of solar panels will therefore be 24% x (100% – 7.5%) = 22.2%.
It is however possible to limit these losses of yield. For example, he is advised to choose new generation solar panels. A new solar panel has a high yield And limits losses to 0.25% per degree above 25 °.
There is also the technique of Surimition of solar panels which allows better ventilation and more optimal yield, because the panels are not directly placed on the roof.
The influence of shade
Shading may have an impact on the yield of a solar panel. A shade can be a tree, a post or even a neighboring mountain, for example. For this kind of situation, It is necessary to make an inventory of potential shades which could impact the installation.
On the other hand, If these are partial shade, they are not necessarily problematic and will not really influence the yield of a photovoltaic solar panel nor the yield of a solar thermal panel.
Solar panel technology
It is essential to choose your solar panels well. The technology used is actually a factor that varies the yield of a solar panel considerably ::
- THE Monocrystalline solar panels : these are these panels that offer the highest yields . Indeed, the yield of these solar panels can reach Between 14% and 19% ;
- THE Polycristalline solar panels : they generally have a maximum yield included Between 11% and 15%. They are a little less effective than a monocrystalline solar panel, especially when the sunshine is low;
- THE Amorphous solar panels : these are the solar panels that offer the lowest efficiency, be Between 5% and 7%. This type of panel works well with a low level of sunshine, but the yield of this solar panel per m² remains lower. These types of panels are rather reserved for specific uses, for example on boats or when hiking.

Solar panels maintenance
Regularly maintaining its solar panels is essential. You have to think of a good rate of cleaning its solar panels.
Actually, well -maintained and cleaned installations would have a yield of 2 to 7% more that those that are not maintained.

The installation of solar panels is an ecological and economical solution. It is necessary to install them while respecting the most optimal conditions in order to obtain the best return. However, It is also necessary to choose how to use them to make them profitable. Two choices are possible:
- Self -consumption : it consists in producing and consuming your own electricity using renewable energies (this does not only concern solar panels, but also other energy sources such as wind turbines for example). In particular, it can no longer depend on the changes in electricity prices, but also to protect the environment by limiting its CO2 emissions. There are also many state aids that allow you to finance the installation of solar panels for its accommodation. With its aid and savings on the guaranteed electricity bill, it is possible to reach a 9% financial return ;
- There Total or partial sale of the energy produced : It is also advisable to consider selling the electricity produced to energy suppliers who have the obligation to buy electricity, or to consume the electricity that we need and sell the surplus. It is necessary to pay particular attention to the power of the installation in the context of the sale of energy, because the price of electricity is directly linked to this power.
