Evolving Technical Features of PVGIS24

Precise Modeling via GPS Geolocation

Precise Modeling via GPS Geolocation

Using advanced Google Map geolocation, PVGIS24accurately identifies the GPS point of the installation. This approach enhances the accuracy of unlimited solar yield simulations by considering site-specific conditions such as altitude, shading, and solar angle.

Multi-Orientation and Multi-Inclination Simulation

PVGIS24has extended its simulation capabilities, now allowing yield calculations for systems with up to three or four sections, each with different orientations and tilts. This advanced feature accounts for every possible angle and orientation, making simulations even more precise for complex configurations.

With PVGIS24, users can simulate installations with two, three, or even four distinct tilts and orientationson a single site, a solution particularly suited for flat roofs and East-West or North-South triangle installations. This optimized calculation enables optimal solar irradiation capture, thereby maximizing the energy production potential of each panel.

Photovoltaic Energy Production Hours with PVGIS24

A key indicator for assessing the profitability of a solar project
Photovoltaic energy production hours refer to the number of hours during which a system produces the equivalent of its rated power (expressed in kWh/kWp). It is not a continuous duration of sunlight but rather an average equivalent production spread over the year.
  • For example, a 1 kWp system producing 1,438 kWh/year is equivalent to 1,438 hours of production at full power.
  • These hours help estimate revenue, energy savings, and most importantly, return on investment (ROI).
The higher the production hours, the more profitable the installation.
A monthly projection to optimize energy use
The month-by-month breakdown allows you to:
  • Plan for production peaks and thus adjust usage (for example, to heat water or charge a solar-powered car in December rather than June in some regions).
  • Adjust storage size (batteries) according to the weaker months.
  • Anticipate seasonal decline and maintain energy comfort.

Using Terrain Shadows

Geographic Site Shadows: PVGIS24automatically integrates shadows caused by nearby hills or mountains that may block sunlight during certain hours. This calculation excludes shadows from nearby objects such as houses or trees, providing a more relevant representation of local conditions.

Modular Approach for Complex Projects

PVGIS24allows for unlimited adjustments of solar yield simulation parameters according to project specifications, such as panel inclination, multiple orientations, or differentiated yield scenarios. This offers unmatched flexibility for engineers and designers.

PV Technology

Over the last two decades, many photovoltaic technologies have become less prominent. PVGIS24 prioritizes crystalline silicon panels by default, which are predominantly used in residential and commercial rooftop installations.

Simulation Output

PVGIS24enhances results visualization by instantly displaying monthly production in kWh as bar charts and percentages in a summary table, making data interpretation more intuitive.

CSV, JSON Export

Some data options deemed less relevant for unlimited solar yield simulations have been removed in PVGIS24to simplify the user experience.

Visualization and Technical Data Reporting

Results are presented as detailed technical graphs and tables, facilitating the analysis of photovoltaic system performance. The data can be used for ROI calculations, financial analyses, and scenario comparisons.
