How much energy do 500 m2 of solar panels produce?

500 m² of solar panels allow significant energy production , but several factors influence the overall efficiency of the photovoltaic installation. The total power generated depends mainly on the quality of the photovoltaic panels , their efficiency, and the sunlight conditions.

On average, a standard solar panel has a peak power of 300 to 400 watts-peak (Wp) . Assuming that each square meter of panels offers an output of 150 to 200 Wp , a surface area of ​​500 m² could theoretically generate between 75,000 and 100,000 Wp, or 7.5 to 100 kWp . This figure represents the maximum power that the installation can achieve under ideal conditions.

In terms of annual production, a system of this size can produce approximately 150,000 to 200,000 kWh of electricity . This estimate varies depending on local sunlight , orientation of the panels , and possible shadows or obstructions . In France, energy production can be affected by seasonal variations , with higher production in summer and reduced in winter.

It is also important to consider the efficiency of solar panels , which can range from 15% to 22%. A high efficiency means that the solar panels convert a greater proportion of sunlight into electricity. For example, a panel with an efficiency of 20% will produce more energy for a given surface area compared to a panel with an efficiency of 15%.

A well-optimized PV installation can also benefit from technologies such as maximum power point tracking (MPPT) and high-quality inverters, which maximize energy production. A 500 m² area of ​​solar panels can produce a substantial amount of electricity , but the exact results will depend on the specifics of the installation and local conditions.

Operating and maintenance costs for 500 m2 of panels

Once the solar panel installation is complete, there are operating and maintenance costs to ensure the proper functioning and durability of the system . These costs are generally low compared to the initial investment, but they are essential to optimize the performance and profitability of the solar panels in the long term.

Maintenance costs include regular cleaning of solar panels to prevent the accumulation of dirt or debris that could reduce their performance . Depending on the region and climate, cleaning may be necessary once or twice a year. On average, the cost of this service is around 500 to 1,000 euros per year for a surface area of ​​500 m².

Operating costs also include periodic verification of the proper functioning of the photovoltaic installation. This includes monitoring inverters and performance monitoring systems, as well as detecting and possibly repairing breakdowns or malfunctions . The costs associated with these annual checks can vary between 300 and 700 euros , depending on the complexity of the system and the services provided by the provider.

In the event of a major breakdown or failure of a solar panel, repair costs can be higher. However, most photovoltaic panels have warranties of 10 to 25 years , covering manufacturing defects and significant yield losses. Inverters, on the other hand, generally have a warranty of 5 to 10 years, with the possibility of extension.

Therefore, you need to budget for possible repairs and replacement of worn components . Total maintenance costs for a 500 m² installation are typically well below €1,500 per year , making it a relatively modest outlay compared to the savings on electricity bills.

Although the operating and maintenance costs for 500 m² of solar panels are generally low, they must be taken into account in the overall assessment of the profitability of the installation. Regular maintenance not only ensures the longevity of the system but also optimizes its performance and efficiency.

The net profitability of 500 m2 of solar panels

Assessing the net profitability of a solar panel installation on a 500 m² surface requires a thorough analysis of the costs and revenues associated with the solar energy produced. This calculation helps determine whether the initial investment will be amortized and whether profits will be made in the long term.

Installation cost and savings

The initial investment for a 500 m² photovoltaic system can vary between 150,000 and 250,000 euros, as mentioned above. However, this investment is usually amortized thanks to the savings made on electricity bills . Depending on the estimated energy production, such a system can generate between 150,000 and 200,000 kWh per year. On average, the value of this energy is around 0.10 to 0.15 euros per kWh, which represents annual savings of between 15,000 and 30,000 euros.

Income from the sale of surplus

In addition to saving on electricity bills , it is possible to generate additional income by selling surplus energy produced. In France, the feed-in tariff for solar energy can vary, but it is generally between 0.05 and 0.10 euros per kWh. Assuming that 30% of the production is sold, this can generate additional income of 2,250 to 6,000 euros per year.
