Case study

A typical family with 3 people living in a T2 has an average annual electricity consumption of 3,000 kWh (2,000 kWh / year in empty and 1,000 kWh / year in empty), which is equivalent to a monthly bill of 60 € ( considering the values ​​of the regulated tariff on a bi-hourly basis with a daily cycle).

The installation of a photovoltaic kit for self-consumption with an installed capacity of 1,000 Wp, occupying an area of ​​7.5 m2 oriented to the south and with a slope close to the local latitude, allows an average annual production of 1,500 kWh / year.

This kit represents an investment of € 1,200 and an annual saving of € 285 in energy, corresponding to a reduction of € 24 in your monthly bill, which represents a payback period of 4 to 5 years.

The energy generated by the system corresponds to the annual energy consumed by domestic equipment, such as:

• Fridge;
• Washingmachine
• Dishwasher

Installing a photovoltaic system will make your home more efficient and could increase your energy class.

Conclusion:

For greater savings, you must ensure that the highest consumptions occur during the photovoltaic panel’s energy production period while consuming as much energy as possible.
