Solar panel performance by month
To cover all the energy demand of your home with a solar list of zimbabwe consumer email panel installation , you should look for a system capable of generating at least the amount of kWh that you usually consume on average per month. Although technology has advanced a lot, today, this is very difficult to achieve. Because, as we have seen before, performance and efficiency do not only depend on the panels, but also external factors such as temperature or the presence of shadows on the panels.
Weather conditions can vary from month to month due to seasonal changes, and this directly affects the performance of the panels. For example, in summer solar radiation is greater because the days are longer, while in winter radiation is less because we have fewer hours of light. Thus, the efficiency of the panels will be lower during the colder months.
However, it is important that you look for systems that perform as well as possible throughout the year, because this will improve the energy efficiency of your home .
Calculating monthly yield
To find out the monthly performance of solar panels, follow this process:
Measuring monthly energy generation. An energy meter connected to the system can record the amount of electrical energy generated in a month.
Determination of monthly incident solar energy. Monthly solar irradiation data can be obtained from official meteorological stations.
Calculating monthly yield. To calculate the yield, divide the energy generated by the incident solar energy and multiply the result by 100 to obtain a percentage.
What is the average performance of solar panels?
Solar panels are classified into three groups according to their performance:
Low performance. They can generate between 150 and 250 W per square meter, with an efficiency of between 14% and 17%.
Medium performance. They generate between 250 and 350 W per square meter, with an efficiency ranging between 18% and 19%.
High performance. They can generate up to 400 W per square meter and their efficiency reaches 23%.
High-performance panels are made from the highest quality materials and the most advanced technologies. Even so, their capacity to transform the energy received into electrical energy is only 23%. For this reason, in most cases, medium-performance panels are chosen, which are cheaper and offer an efficiency close to 20%.
The performance of solar panels is a very important factor when making your decision about the installation of your home or business . Another very important factor is who you trust with said installation. At Naturgy, we are at your disposal.
Storage installation: This involves replacing or installing storage devices. Households will receive a subsidy of between 140 and 490 euros per kWh. This amount is the same for other sectors.
