Solar Panels Are Capable Of Turning Sunlight Into Electricity, And We Will Discover Together How Much A 550W Panel Can Generate In Energy.
First, we need to understand three things: the power of the solar panel, the solar irradiation of the location, and the efficiency of the system. The power is the strength of the panel, and solar irradiation varies according to the region – after all, Brazil is quite large and the sun is not the same everywhere. And efficiency? Well, that relates to the natural losses of the system. Now discover how many kWh a 550W solar panel can generate.
Calculating The Energy, A Simple Formula
Now, let’s get to the point: calculating the generated energy. The formula is simple: the energy generated monthly is equal to the power of the panel times the average daily solar irradiation of the location, times the efficiency of the system, times the days in the month, all divided by 1000. Easy, right?
Let’s use as an example a 550W panel installed in Belo Horizonte, with an average solar irradiation of 5.17 kW/m² per day and an efficiency of 80% (considering 20% losses). Making the calculations, this panel will generate about 68.24 kWh per month.

Regional Variations, The Sun In Favor Of Energy
However, this generation varies from city to city. In São Paulo, for example, with lower irradiation, the generation drops to 58.47 kWh/month. In Brasília, which has a strong sun of 5.28 kW/m² per day, generation increases to 69.69 kWh/month. Therefore, location is key when planning your solar installation.
