7. Residential Consumption Information

Base for Solar Self-Consumption Simulations

This section provides an essential foundation for simulating your solar self-consumption project with precision and maximizing your energy autonomy gains. The "Residential Consumption Information" section provides key data for simulating solar production for self-consumption with PVGIS. By entering your consumption habits (split by day, evening, and night, weekdays and weekends), you will get an accurate estimate of your electricity consumption, which will serve as a reference for:

1. 1. Adapt solar production to your needs:

   Consumption data helps simulate the most suitable solar installation to cover your energy needs when you need it the most.

2. 2. Optimize self-consumption:

   By understanding your peak consumption periods, PVGIS can estimate how much of your solar production will be used directly, thus reducing your dependence on the public grid.

3. 3. Forecast potential savings:

   By comparing estimated solar production with your residential consumption, PVGIS calculates the percentage of energy you can self-consume, providing an estimate of savings on your electricity bill.

8. Commercial Consumption Information

Base for Solar Self-Consumption Simulations

This section is essential for commercial solar simulations as it helps tailor solar production to the specific needs of the business, promoting better energy autonomy and reducing operational costs.
The "Commercial Consumption Information" section provides crucial data for performing solar self-consumption simulations adapted to business needs. By entering your electricity consumption habits (split by time of day on weekdays and weekends), this data serves as a reference for:

1. 1. Adapt solar production to business hours:

   Consumption data helps simulate a solar installation that precisely matches the times when your business needs the most energy, maximizing the use of the solar energy produced.

2. 2. Optimize the self-consumption rate:

   Based on your consumption peaks, PVGIS estimates the proportion of solar production that will be directly consumed, reducing electricity costs from the grid.

3. 3. Forecast savings and return on investment:

   By comparing solar production with your energy needs, PVGIS calculates the potential for self-consumption and estimates the savings you can achieve on your electricity bills, providing a key indicator to evaluate the project's profitability.

9. Recommended Losses by Default for a Solar System

These recommended default losses help to provide an estimate that takes into account the practical limitations of your solar system, ensuring a more accurate production forecast.
Solar production simulations incorporate estimated losses to provide a realistic prediction of usable energy. These losses are default recommended percentages based on the average performance of solar installations. Here are the default losses typically recommended for each component and their impact:

1. 1. Cable Losses (1-2%):

   • Cable losses are inevitable since the electricity produced by the panels must be transported to the inverter and then to the grid or consumption meter.
   • Generally, an estimate of 1 to 2% cable losses is recommended. This percentage depends on the length and gauge of the cables: longer or smaller cables result in higher losses.
   • Using high-quality cables with an appropriate gauge can minimize these losses.

   PVGIS24 estimates the cable loss by default at 1%.

2. 2. Inverter Production Losses (2-4%):

   • The inverter converts the DC power produced by the solar panels into usable AC power. This process is not perfect and leads to losses.
   • On average, inverter losses are estimated at 2-4%. High-quality modern inverters can reduce these losses, while less efficient equipment can increase them.
   • This percentage is based on the conversion efficiency of the inverter, which typically ranges between 96% and 98%.

   PVGIS24 estimates the inverter production loss by default at 2%.

3. 3. Solar Panel Production Losses (0.5-1%)

   • The panels themselves experience efficiency losses due to external factors such as dirt, partial shading, high temperature, and the natural degradation of solar cells over time.
   • The performance of panels naturally declines over time (about 0.5% to 1% per year depending on materials). The performance loss is due to physical degradation, such as glass yellowing, corrosion, and cracks in the cells.
   • Regular maintenance, such as cleaning the panels and optimizing their placement (to limit shading), can reduce these losses.

   PVGIS24 estimates the solar panel production loss by default at 0.5%.

By using these default loss values, PVGIS gives you a reliable and realistic estimate of your solar production. These percentages are based on industry averages and help account for the gaps between theoretical and actual production, incorporating the physical variables that affect the performance of each component.

10. Maintenance Information

This maintenance information helps plan regular maintenance to maximize the photovoltaic system's production and reduce long-term costs. By keeping the system in good condition, you prevent performance losses and ensure the profitability of your solar investment.
The "Maintenance Information" section provides key details for planning and estimating the maintenance costs of a photovoltaic system. Regular maintenance is essential for ensuring optimal performance and extending the system's lifespan. Here are the maintenance elements considered in this section:

1. 1. Annual maintenance of the photovoltaic system (% of the total system cost):

   • This percentage indicates the share of annual maintenance costs relative to the system's initial cost. Generally, maintenance represents about 1 to 2% of the system's total cost per year.
   • This estimate covers necessary interventions to clean the panels, check the wiring and inverter, and ensure the system is working correctly.
   • Regular monitoring helps prevent performance losses related to dirt, wear, or component degradation.

2. 2. Maintenance cost per Watt

   • The cost per watt provides an estimate of the annual maintenance expenses based on the installed power. This value is useful for large installations, as it allows easy calculation of costs based on the system's size.
   • By indicating this cost, you can obtain an accurate estimate of your annual maintenance expenses, proportionate to the size of the installation.

3. 3. First maintenance period after commissioning

   • This information helps plan the first inspection or maintenance after installation. Generally, the first maintenance is recommended within 6 to 12 months of commissioning to ensure the system is functioning perfectly.
   • The first maintenance is important for detecting and correcting any early issues, such as installation defects, panel alignment, and inverter performance.
