This week we focus on those people who have solar installations which work normally for them during the warm months of the year, which correspond to those with the greatest number of hours of sunshine, but who each year with the worst months of the year have significant problems due to insufficient generated energy. This usually happens mostly in the winter months in November, December and January, that is, when the path of the sun in the sky is lower and that causes fewer daylight hours; therefore the plates do not generate the same energy as other months.
This problem usually occurs mainly for two reasons: - The first cause may be due to poor sizing in the assembly of the installation, which was carried out at the time without taking into account the lower solar radiation in the winter months. It causes that the spring and summer months are not appreciated since a lot of solar radiation is received. The problem arises in winter when the radiation is 60% less than that received in summer. For this reason, it is so important that the solar kit for use throughout the year be sized based on the month of least radiation, December. - The second cause may be due to the fact that the user is consuming more electricity in the home than initially agreed upon when the installation was carried out or when the solar kit was purchased. With which the current dimensioning of your solar equipment will be insufficient.
To solve the problem, at Wccsolar we will ask you to indicate the devices you use and their number of hours of use as well as the current components of your solar installation such as solar panels and their power, battery capacity, and inverter power and of the solar regulator. With these data we will be able to diagnose the cause and indicate the best solution so that the solar installation always works well and optimally all year round. In most cases, after the calculation that we will carry out, you will only have to add solar panels to cover the deficit of solar energy capture in the months of low radiation. While in other installations it may be due to a lack of energy storage capacity in the batteries. We will also make sure that you have the appropriate cable thickness in each of the sections of the installation. Since we often find equipment with thin cable sections of 1.5 or 2.5 mm2 as if it were alternating current at 230V when they should be much thicker in the parts where the current is direct. These cable errors mean voltage and energy losses throughout the circuit and a serious problem in the general operation.
Whatever the cause, at WccSolar we will give you the appropriate and balanced solution to your needs. Always thinking about its functionality and with the appropriate solar material, which can vary depending on the type of consumption connected to the power inverter. If it is solar energy for seasonal use in summer, on weekends, or for daily use as a habitual residence. Contact us to receive information.
