PVGIS.COM provides information on solar radiation and PV system performance for any location in the world
PVGIS 5.2 / PVGIS 24
PVGIS 5.2 is the historical form of PVGIS used since 2007. PVGIS 24 is a more modern form of PVGIS.COM in 2024. The estimates and simulations are identical, only the form of presentation and the Printed states are different.
PVGIS 5.2
PVGIS 5.2 is the free standard version that made PVGIS
the world's No. 1
Solar weather data estimates.
PVGIS is the most reliable source of geographic data
to the world. Almost all solar productivity calculation and simulation software
use PVGIS in geographic data.
PVGIS 24
PVGIS 24 is a free evolution of PVGIS 5.2 for
solar installations only
connected to the grid, mainly on the roof. PVGIS 24 is
intended for installers
and
solar craftsmen, more and more numerous to date.
PVGIS 24 allows growers to
"residential"
and "commercial" independent companies to check and compare
the "residential"
and "commercial"
solar production of their current or future installation.

PVGIS 24 automatically options shadows due to local hills or
mountains that can be
block the light during certain hours
of the day. This calculation does not take into account the
shadows from very close objects such as houses or trees.
Solar radiation database: Geographic database of solar radiation
PVGIS offers four different databases on solar radiation with an hourly revolution. PVGIS 24 automatically determines the database corresponding to your geographical production site.
PV Technology
In twenty years, many photovoltaic technologies have become marginal. On residential and commercial roofs, the majority of solar installations are made with panels made of crystalline silicon cells. This is the default choice of PVGIS 24.
Simulation Output
PVGIS 24 improves the reading of solar production month by month
by offering a visualization
immediate on-screen production of the month-by-month productions,
in kWh in the histogram bars and
in
Percentage in a summary table.
System Loss: System Losses
This is the most important evolution of PVGIS 24.
PVGIS 5.2 provides a default value of 14% for overall losses in the
production system
of solar electricity.
This overall loss is estimated for 20 years of operation, allowing
roughly estimate an average annual solar production with annual variability
generally close to 3%. PVGIS 24 proposes to estimate solar
production in the first year
and to develop this operation for 20 years, taking into account the decline in
production of photovoltaic panels on a global average of 0.5% per year (see work by Sarah and
Jordan Kurtz) and seasonal variability.
Estimated solar production year by year
will be very useful when extrapolating to financial estimates such as the
IRR
(Internal Rate of Return and ROI (Return on Investment).
CSV, Json and radiation extract
As these options and information bring little added value to solar production simulations, they have been updated to version PVGIS 24.
PVGIS:
the FREE
tool to estimate photovoltaic production
Investing in solar panels is an option, but at what cost?
How to determine if
Will the purchase of a photovoltaic device be profitable?
And if so, when will it pay off?
When you contact an installer for a quote, they will certainly
give you an estimate.
However, how accurate is this estimate?
It is surprising to note that finding a precise answer to this question
is an exercise
difficult.
The calculation of the production of solar panels requires the consideration of many factors, such as the type of material, the age of the panels, the shading, the amount of sunlight, the orientation, tilt, and many more. For a few years now, there has been a free online solution which allows you to obtain an estimate of the production of solar panels: PVGIS "Photovoltaic Geographical Information System".
PVGIS analyzes GPS, weather and other information to determine
the profile
of a solar device, then it estimates the photovoltaic production.
Using data from Google Maps, this software is both accurate and easy to use.
Forget divination, tarot cards and signs in coffee grounds, PVGIS has it
all
to convince you!
PVGIS is an online tool, accessible to everyone with a simple click.
It was launched by the European Commission in 2007 with the aim of supporting the development of renewable energies by providing as much information as possible to citizens.
Key features of the PVGIS tool
The performance of a solar panel depends on many factors such as orientation,
radiation
solar power, sunshine time, temperature, shading, equipment used, etc. PVGIS
performs calculations by cross-referencing this data to estimate the production
of your solar
panels.
PVGIS offers sunshine maps (irradiation in kWh/m²) and temperature data
for all regions of the world. It takes into account
solar irradiation as well as
the elevation of the surrounding terrain.
PVGIS provides optimal data for tilt and azimuth!
This is very

of energy production
of your solar installation, whether real or hypothetical. However, it is important to
understand these numbers.
Your annual photovoltaic production displays the yield in kWh/kWp/year.
Energy is expressed in kWh (kilowatt-hour):
it is the product of the power (in W) per
the
time (in h). Thus, 1 kWh corresponds
to the production of one kilowatt (1,000 watts) in one
hour.
The power of a panel is estimated according to one hour of production in kWp (kilowatt peak).
The kWp represents the maximum expected production of a photovoltaic panel
in
conditions
in terms of location and use.
