When people start looking into generating their own energy and even in self-consumption with solar panels at home, it’s common for many questions to arise.
How many solar panels do I need? is one of the most frequent questions. Solar energy has become a sustainable and efficient option in Argentina, and can be put into practice.
With the urgency to reduce expenses and seek renewable energy sources, many wonder about the ideal quantity to supply a household’s energy needs.
How many solar panels do I need for my house?
It’s time to figure out how many solar panels are needed to power a house.
Determining the quantity will depend on various parameters, including monthly electricity expenditure and the photovoltaic energy generation in your area.
Self-consumption: How many solar panels do I need for a house?

If we consider a house of about 60 square meters, it’s estimated that a residence of this size may require between 4 to 6 solar panels, but the exact number will depend on its energy consumption.
On the other hand, for a house of approximately 100 square meters, the average energy consumption can be around 350 kWh per month. However, this will vary depending on the appliances in the household and their frequency of use.
Taking into account this energy expenditure, a system that produces at least that amount of electrical energy will be needed.
According to specialists, in the case of opting for 300 W solar panels each, under the best conditions, each panel can produce around 1.2 kW/h per day. Therefore, to meet the 350 kWh per month consumption, the following is required:
- Calculate daily consumption: 350 kW/h / 30 days in the month = 11.667 kW/h/day.
- This daily consumption is divided by the daily production of each panel: 11.667 kW/h ÷ 1.2 kW/h per panel. This results in 9.73 panels.
Thus, a total of 10 300 W solar panels are needed.
To determine how many solar panels are needed for a house, it’s necessary to consider its electrical expenditure and the house’s area. According to the gathered information, this may vary depending on each household’s electrical usage.

The importance of quality in solar panels
Solar panels represent a long-term investment, generally designed to operate for 25 years or more. It’s essential that the installed modules provide the promised quality, as otherwise, the return on investment is affected, and the customer could experience performance issues.
Solar modules and inverters are the most sensitive components of a photovoltaic system, but it’s also important to pay attention to the wiring, connectors, and overall installation quality, as any failure in these elements can compromise the efficiency and safety of the system.
