Photovoltaics in Salzburg
What determines your yield in Salzburg
Salzburg sits in a temperate climate — solar irradiation is lower than further south, but comfortably sufficient for efficient operation. A well-planned system here reaches roughly 950 kilowatt-hours per year for every 6 m² of module area.
Your yield is decided by your roof, not by the province. Four factors set it:
- Orientation — south is good, and a properly laid out east-west array achieves just as much
- Roof pitch — 15° to 40° is the favourable range; flat roofs are mounted on frames
- Shading — even one shaded section pulls down the output of the entire array
- Consumption profile — it decides how much you use yourself and how much you feed in
We establish these four on site, before anyone talks about modules or prices. Planning, installation and support come from Elixhausen near Salzburg.
An old roof: renovate first, then mount
A PV system stays on the roof for 25 years or more. If the roof covering is near the end of its life, renovation belongs before installation — otherwise the array has to be removed and re-mounted later.
We don’t carry out the roof work ourselves: we cooperate with roofing firms and coordinate sequence and scheduling so that renovation and installation mesh. Tell us how old your covering is when we visit — we’ll look at it together.
Photovoltaics: electricity from solar energy
Photovoltaics is a method of generating electricity from solar energy. At the heart of the technology are solar cells, which use the photovoltaic effect to produce electrical energy from sunlight.
Photovoltaics thus makes an important contribution to using renewable energy and reducing CO₂ emissions. With the sun as an inexhaustible source, electricity can be generated in an environmentally friendly way, and continuous technological progress keeps improving efficiency and adoption.
How the photovoltaic effect works
The photovoltaic effect occurs when light hits the solar cells and sets electrons in motion. Solar cells consist of several layers made from semiconductor materials such as silicon. When incoming light excites electrons in the silicon layer, electrical charges are created. An internal electric field within the solar cell directs these charges in one direction, producing current.
The solar cells are combined into solar modules, which in turn are connected into photovoltaic systems. These systems can be installed on building roofs or set up on open land. The direct current they produce is converted into alternating current by an inverter and can then be fed into the grid as usable electrical energy.
Is there a difference between a photovoltaic system and a solar system?
Yes. A photovoltaic system is used specifically to convert sunlight into electric current. It consists of solar cells made of silicon or other materials that generate electrical energy under sunlight. These systems produce direct current, which is converted into alternating current for use in the household or the grid. A solar system, on the other hand, is a general term for all systems that use solar energy. Besides photovoltaics, it includes solar-thermal systems for hot water or heating support, and solar space heating.
The main difference lies in function and application. While photovoltaic systems convert sunlight directly into electricity, other solar systems use the sun's heat to warm water or rooms. Photovoltaics is therefore ideal for power generation in residential complexes, commercial businesses and large solar power plants, while solar-thermal systems cover hot-water and heating needs. Both types play an important role in using renewable energy and reducing our ecological footprint.
Your benefits
All advantages at a glance
A photovoltaic system has numerous advantages worth noting: green, sustainable energy with financial benefits for the user — private individuals and companies alike.
Components of a photovoltaic system
A photovoltaic system consists of several components working together to convert sunlight into electricity:
-
Solar cells & modules
The heart of the system: semiconductor materials — usually specially treated silicon — convert sunlight directly into direct current.
-
Inverter
Converts the generated direct current into alternating current suitable for household use, which can be fed into the grid or consumed directly.
-
Mounting system
Brackets and frame-like structures hold the modules securely in the best position — on the roof or another suitable surface.
-
Battery storage (optional)
Stores surplus electricity for use when the sun is not shining — at night or in bad weather.
-
Monitoring system (optional)
Track system performance, measure generated and consumed electricity and detect problems quickly.
Generating your own solar power: requirements
Before you start generating your own solar power, several requirements need attention: a suitable area for the solar modules — ideally a roof, façade, open space or fence —, a favourable geographic location and the right orientation of the modules. Add to that the financial investment for purchase and installation, plus a feed-in meter and, where appropriate, suitable storage technology. Technology keeps evolving, so staying up to date matters. In the end, the solar power you generate reduces your need for conventionally produced electricity and your dependence on energy suppliers.
Strength of solar irradiation
Solar irradiation in Salzburg varies with geography and weather. Salzburg has a temperate climate, so irradiation is somewhat lower than in more southern regions — but still easily sufficient to run a photovoltaic system efficiently.
Irradiation intensity directly affects system output: the stronger the sun, the more electrical energy the system produces. Weather conditions such as clouds, fog and precipitation reduce irradiation. Efficient orientation of the system towards the sun is therefore decisive for maximising output.
Roof pitch
The roof pitch determines the angle at which sunlight hits the solar cells and thus how much solar energy they can absorb. The optimal pitch depends on geographic location, roof orientation and the system's purpose. In general, a pitch between 15° and 40° is best for energy production.
For pitched roofs, 30° to 45° is ideal. On flat roofs, mounting frames can achieve a tilt of roughly 10° to 30°. In areas with lower irradiation a steeper pitch can improve the angle of incidence — as guide values, about 30° suits Central Europe, 20° the Mediterranean and 45° Northern Europe.
Roof orientation
In Salzburg, south-facing or east/west-facing roofs work best — these are the best orientations for photovoltaic systems. A properly configured east/west orientation can deliver similarly good yields.
Both flat and pitched roofs are suitable: a flat roof allows more flexibility since modules can be set at a variable angle, while on a pitched roof the modules follow the roof's fixed pitch.
Shading
If part of the solar cells is shaded, the output of the whole system suffers. Common causes include trees or buildings, but cloud shadows or dust also reduce the light reaching the cells.
The best remedy is choosing the right location, away from shade sources. Where that is not possible, special mounting systems or "optimisers" can minimise the impact. It also pays to maintain the area around the system regularly so no new shade sources block the modules.
Your home's electrical installation
Before integrating the PV system into the existing wiring, the electrics should be checked: can the house grid handle the additional load? Existing cables and fuses may need reinforcing or extending. Feeding the solar power into the house grid requires appropriate feed-in equipment and correct wiring throughout.
For efficient use of your solar power, run appliances such as washing machines during sunny hours, or install a battery — this uses surplus power directly and reduces dependence on the public grid.
Sizing: how large should my PV system be?
When sizing a photovoltaic system, choosing the right capacity ensures optimal energy production. These factors feed into the calculation:
- Strength of solar irradiation at the site
- Roof pitch and orientation
- Shading from trees, buildings or other obstacles
- Existing house electrics and your consumption profile
Depending on your consumption profile, the system size can be tuned to maximise self-consumption or feed surplus energy into the grid. Even minor shading can significantly reduce output — so we recommend consulting an expert for a precise system design.
Subsidies in Salzburg
How to get the subsidy
The easiest way is through us: we work with renowned subsidy specialists who guarantee reliable processing. Of course you can also research and apply for the subsidies yourself:
-
Submit the application electronically
Via the Salzburg subsidy manager — have all required information ready.
-
Obtain construction clearance
Before starting to build the system, make sure you have all necessary permits and documents to avoid delays.
-
Submit the settlement documents
Once the system is installed, provide the subsidy office with all receipts and evidence required for disbursement. Full compliance with the requirements and deadlines is essential for a successful application.
Why are there subsidies?
A main driver is the State of Salzburg's climate and energy strategy, which aims to raise the share of renewables in the energy supply significantly and contribute to climate protection. Financial support enables more citizens, companies and public institutions to invest in photovoltaic systems, accelerating the expansion of renewables and reducing dependence on fossil fuels.
In Salzburg the subsidy takes the form of a direct grant towards gross investment costs. This increases demand for photovoltaic systems and supports regional value creation and jobs — the subsidies pursue both ecological and economic goals.
What is subsidised?
The state subsidy in the Salzburg region supports measures and projects contributing to sustainable energy generation, with a particular focus on photovoltaic systems. Requirements include compliance with technical standards and the use of renewable energy for power generation.
Smaller systems for single- and two-family homes as well as larger systems for commerce and agriculture are eligible; maximum rates vary by system type up to a certain percentage of eligible costs. The Salzburg state subsidy can also be combined with other programmes — federal subsidies, municipal subsidies or programmes from energy providers — optimising the financing.
Costs and financing: is a PV system worth it?
The costs cover purchase and installation of the photovoltaic system, accessories and the electrical connection, plus running costs for maintenance and insurance. Financing can work in several ways: equity or a loan, state subsidy programmes, or renting/leasing a PV system.
Whether a PV system pays off depends on individual factors: solar irradiation at the site, system size, feed-in tariffs for the generated electricity and your self-consumption share. Also factor in subsidies — state programmes often provide financial support or tax incentives.

Installing a photovoltaic system
Installing a solar system is a process with several steps — proper execution is decisive for the system’s maximum performance:
-
Site inspection
A thorough check for optimal sunlight exposure and enough space for mounting the solar modules.
-
Mounting the modules
On the roof, façade, fence or carport — fastened securely and aligned to the sun for maximum yield.
-
Installing the inverter
Easily accessible and near the fuse box — it converts the direct current from the modules into alternating current.
-
Wiring and metering
Proper, safe cabling including a suitable metering system to measure the energy produced and feed it into the public grid where applicable.
-
Testing and commissioning
All connections are checked, the modules connected to the inverter, and the entire system given a thorough inspection and function test.
After installation comes maintenance
After installation, regular maintenance is essential: inspections, cleaning and, where necessary, repairs keep the system performing optimally over its long service life.
Inspections should happen at regular intervals — for example every twelve months — checking all components for damage or wear, with particular attention to the modules, wiring and inverters. Any defect should be repaired promptly to protect other components. This ensures high energy production and early detection of problems.
