Photovoltaic systems are now one of the most effective ways for a household to reduce its electricity bill. One of the most common questions we receive is:
“How much electricity does a 10kW photovoltaic system produce?”
The answer depends on several factors, but Greece has some of the highest levels of sunshine in Europe, making photovoltaic systems particularly efficient.
Average production of a 10kW photovoltaic system
In Greece, a 10kW photovoltaic system produces an average of:
14.000 – 16.500 kWh per year
This means that every 1 kW of installed capacity produces approximately:
1.400 – 1.650 kWh per year
High output is mainly due to:
- the country’s abundant sunshine
- the many clear-sky days
- the long hours of sunshine in summer
For example, in Attica a 10kW system usually produces approximately 15.000 kWh per year.
Average daily and monthly production
A photovoltaic system does not produce the same amount of energy every month. Output is significantly higher in summer than in winter.
Average output
- 40 – 45 kWh per day
- 1.200 – 1.400 kWh per month
Of course, these are annual averages.
Example of output throughout the year
A typical 10kW photovoltaic system in Greece can have approximately the following output:
January
400 – 600 kWh
400 – 600 kWh
March
1.000 – 1.200 kWh
1.000 – 1.200 kWh
May
1.400 – 1.600 kWh
1.400 – 1.600 kWh
July
1.600 – 1.800 kWh
1.600 – 1.800 kWh
September
1.200 – 1.400 kWh
1.200 – 1.400 kWh
December
350 – 500 kWh
350 – 500 kWh
As you can see, in summer, output can be up to 3-4 times higher than in winter.
How much of a home can a 10kW photovoltaic system cover?
The average electricity consumption of a Greek household is approximately:
4.000 – 6.000 kWh per year
This means that a 10kW system can comfortably meet the needs of a large home, even if it uses:
- multiple air conditioners
- a heat pump
- an electric car
- a water heater or other energy-intensive appliances
In many cases, output can even cover additional consumption.
Factors affecting output
The actual output of a photovoltaic system depends on several technical factors.
The most important are:
Orientation
The ideal orientation for maximum output is south.
Panel tilt
In Greece, the ideal tilt is approximately 25° – 30°.
Shading
Trees, chimneys, or other buildings can reduce output.
Equipment quality
Performance also depends on:
- the quality of the photovoltaic panels
- the inverter
- proper design and installation
Installation location
Production varies slightly depending on the region:
Athens / Southern Greece
15.000 – 16.500 kWh
15.000 – 16.500 kWh
Northern Greece
13.500 – 14.500 kWh
13.500 – 14.500 kWh
Crete / Islands
up to 17.000 kWh
up to 17.000 kWh
Is a 10kW solar system enough for a home?
In most cases, yes.
A 10kW system can cover:
- a large home with high energy consumption
- a home with a heat pump
- a home with an electric car
- a family with high use of electrical appliances
The exact capacity each home needs depends mainly on:
- annual electricity consumption
- available installation space
- the net billing model
Would you like to know how much a solar system could produce at your home?
A 10kW solar system in Greece produces approximately 14.000 – 16.500 kWh per year, enough to fully cover the consumption of an average home.
