Did you know that the performance optimization of a photovoltaic is a process that starts before the purchase of a photovoltaic system and goes after the installation of it? Read in this article that will optimize the performance of your photovoltaic system.
Key points of the article:
– Investment in quality.
– Watch out for the shadows.
– Selection of appropriate installers.
– Cleaning of the panels.
– Use of monitoring applications.
– Reduce energy consumption.
The performance of a photovoltaic system defines the real benefit accruing to an individual from his or her residence or a professional of his business.
This is the main reason why two persons to install, for example, pv 10 kW, but to have a different efficiency. This means that one of the two will have a reduced profit.
The factors that determine the efficiency of a photovoltaic are many, starting before buying, and continue after the installation.
In this article we will look at how to achieve maximum efficiency of a photovoltaic system so you know what you need to do before you install a pv and the steps you should do after the installation.
Operations prior to the installation
1. Performance optimization of a photovoltaic investing in quality
As quality is the solar panel, the higher performance will have your photovoltaic system.
The panels are made of cells within which turns the sunlight into energy. Although, that would be great for the panel to be able to turn it into a stream of all the energy you receive, this is not possible.
As it progresses the technology of the panels, are becoming more and more efficient. In the last 5 years, the performance has been increased by 15%-20%. However, not all are manufactured the panel in the same way. The materials used for each, determine both the performance and the price, of course.
Conventional panels have an efficiency rate of 11% -15%. Note that the most efficient solar panels have efficiencies of about 20%.
The less-efficient panels, to occupy a greater surface to allow them to reach the levels of the most efficient.
Of course, the most efficient solar panels are more expensive. As we have mentioned in many articles, we suggest to you the highest quality panels, although more expensive. Don't forget that it is an investment of 25 years and the depreciation is achieved quickly in the first years.
2. Avoid shading for performance optimization of a photovoltaic
From the moment the solar panels produce energy from solar light, it makes perfect sense any shadow causes a decrease of efficiency.
This, however, is not known to many stakeholders is the impact of the shading even in a single hive of a panel.
You should be aware that if there is shading even in a beehive, are directly affected and the neighboring cells, as well as the shaded hive acts as a resistor. This has as a result, may not be fully efficient and the neighboring cells, something that affects the entire performance.
The high trees or neighboring buildings are the most frequent reasons for shade. So very important role in this case you will play the office will undertake the design of your project.
3. Select the appropriate installers
There are few cases in which many stakeholders have requested, only the purchase of a photovoltaic system and trying out installation by claiming that they have the knowledge.
It is not enough to have experience in facilities or to work his hands in order to be able to install successfully on a photovoltaic system. Technically it is possible but it is necessary that the work be performed by a qualified licensed installers to allow the solar to be cost-effective.
Another thing I don't know a lot of people is that the solar panels are not as efficient when high ambient temperatures. Most people consider that the high temperatures help but exactly the opposite is happening. Another solar light and temperature. The panels need a lot of sunlight and no high temperatures.
This means you are required to have the proper distance between the panels and the roof so that there is easy passage of air and to not overheat the panels.
If the panel is not placed correctly, you will not receive the necessary solar energy and produce less current.
So to get the most out of your photovoltaic system, trust the experts.
Actions after installation
4. Performance optimization of a photovoltaic with cleaning of the panels
The solar panel does not consist of moving parts, so the required maintenance is easy and minimal.
The dust and the dirt that accumulates on the panels is one of the reasons for the reduction of profitability. During the course of a year, it is estimated that there is a reduction in efficiency of 5% due to dust and dirt.
If you live in areas that rarely rains, then it builds up even more dust and the reduction of the efficiency can reach 20%.
The only thing that you need in these cases is a simple cleaning of the panels once a year.
It is a process that you can make yourself with common cleaners.
5. Use recording applications performance
One of the most important achievements of the technology in the field of photovoltaics is the applications that record in real time the performance of a photovoltaic system.
Through these applications, the owner receives interesting statistics for the photovoltaic.
Knowing what hours of the day is more efficient and which months. If you observe any significant differences in comparison with previous periods, you may come to the conclusion that something is not going well and to investigate the causes of a reduction in the efficiency.
If this sounds a lot of work, ask the office that would work if it provides services monitoring.
At ΙΩΝΙΚΗ Renewables, we provide these kinds of services. Every day, our engineers monitor the statistical data of our clients' photovoltaic systems and resolve any issues that arise.
Our Classic packages that include Huawei inverters come with the cloud application FusionSolar, for monitoring. Our Premium and Elite packages with SMA inverters include the Sunny Portal cloud application.
6. Reduce the number of electrical appliances that you use at the same time
For the end we left a factor that requires daily effort on your side.
There are very few households waste more electricity than you need.
To avoid unnecessary power consumption, it will make your photovoltaic system more efficient, while at the same time will save you more money that you can spend elsewhere.
Things of everyday life that seem small and insignificant, in reality, can help in a significant way.
For example, if you don't watch tv, there's no reason to be open and consuming power. If the dishwasher is in operation, you could avoid to put a vacuum cleaner, of course, if there is time in your schedule for another time.
Generally, the fewer electrical devices operate at the same time, the more benefit you get. The benefit, which will have a direct striker in your pocket.
Just consider that with a 10 kW solar panel in a household that consumes 13,000 kWh annually with all electric appliances, such as kitchen, water heater, heat pump, air conditioning, irrigation pump, electric bike chargers, etc., the household saves approximately €1,775 annually. Over the 25-year lifespan of a solar panel, the savings amount to €44,375. From this amount, we will subtract about €10,000, which was the cost of purchasing and installing the solar panel, so a household will save a net amount of €34,375 that they would have paid if they did not have solar panels.
What can you do with about €35.000; This is an answer that will give you by yourself.
Conclusion for the performance optimization of a photovoltaic
As you will have realised by now, the efficiency of your photovoltaic system starts from the market research that will make the suitable equipment. Focus on quality and our experienced licensed installers.
At ΙΩΝΙΚΗ Renewables, we have expertise in the study and installation of photovoltaic systems. We have installed photovoltaic parks, as well as photovoltaic systems for homes and businesses throughout Greece, including on islands. We undertake all the processes from potential financing of the project, the study, the submission of documents, the installation, and we deliver your photovoltaic system ready to use. Additionally, our photovoltaic packages come at highly competitive prices.
