Mosta, located in Malta at a latitude of 35.9142 and longitude of 14.4253, is an advantageous location for solar power generation due to its high sunlight exposure throughout the year. The energy production from installed solar panels fluctuates with the change in seasons; it averages 7.96 kWh per day per kW of installed solar during summer, reduces to 4.21 kWh/day/kW in autumn and further drops to a minimum of 3.32 kWh/day/kW during winter months due to shorter daylight hours and less intense sunlight. However, it rebounds back up to an average of 6.65 kWh/day/kW in spring as the sun's intensity increases.
For a fixed panel installation at this location, tilting the panels towards South at an angle of approximately 31 degrees is ideal for maximizing sunlight absorption all year round.
Despite these promising figures for solar energy generation, there are certain local factors that could potentially impede optimal performance of solar installations in Mosta - strong winds and heavy rainfall being prime examples among them. These weather conditions can lead to physical damage or soiling on the panels which would subsequently decrease their efficiency.
Preventative measures such as installing robust mounting structures that can withstand high wind speeds can help mitigate potential damage caused by storms or gusty winds while regular cleaning schedules should be maintained especially during rainy seasons when dirt accumulation on panels might occur more frequently than usual.
In conclusion, Mosta offers significant potential for efficient year-round solar power generation given its geographical coordinates; however careful consideration has to be given towards suitable installation techniques and maintenance practices considering local environmental factors.
Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.
So far, we have conducted calculations to evaluate the solar photovoltaic (PV) potential in 48 locations across Malta. This analysis provides insights into each city/location's potential for harnessing solar energy through PV installations.

Solar output per kW of installed solar PV by season in Mosta
Seasonal solar PV output for Latitude: 35.9142, Longitude: 14.4253 (Mosta, Malta), based on our analysis of 8760 hourly intervals of solar and meteorological data (one whole year) retrieved for that set of coordinates/location from NASA POWER (The Prediction of Worldwide Energy Resources) API:
 
Ideally tilt fixed solar panels 31° South in Mosta, Malta
To maximize your solar PV system's energy output in Mosta, Malta (Lat/Long 35.9142, 14.4253) throughout the year, you should tilt your panels at an angle of 31° South for fixed panel installations.
As the Earth revolves around the Sun each year, the maximum angle of elevation of the Sun varies by +/- 23.45 degrees from its equinox elevation angle for a particular latitude. Finding the exact optimal angle to maximise solar PV production throughout the year can be challenging, but with careful consideration of historical solar energy and meteorological data for a certain location, it can be done precisely.
We use our own calculation, which incorporates NASA solar and meteorological data for the exact Lat/Long coordinates, to determine the ideal tilt angle of a solar panel that will yield maximum annual solar output. We calculate the optimal angle for each day of the year, taking into account its contribution to the yearly total PV potential at that specific location.
Seasonally adjusted solar panel tilt angles for Mosta, Malta
If you can adjust the tilt angle of your solar PV panels, please refer to the seasonal tilt angles below for optimal solar energy production in Mosta, Malta. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 31° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 20° South in Summer | 40° South in Autumn | 50° South in Winter | 28° South in Spring |
Our recommendations take into account more than just latitude and Earth's position in its elliptical orbit around the Sun. We also incorporate historical solar and meteorological data from NASA's Prediction of Worldwide Energy Resources (POWER) API to assign a weight to each ideal angle for each day based on its historical contribution to overall solar PV potential during a specific season.
This approach allows us to provide much more accurate recommendations than relying solely on latitude, as it considers unique weather conditions in different locations sharing the same latitude worldwide.
Calculate solar panel row spacing in Mosta, Malta
We've added a feature to calculate minimum solar panel row spacing by location. Enter your panel size and orientation below to get the minimum spacing in Mosta, Malta.
Our calculation method
- Solar Position:
We determine the Sun's position on the Winter solstice using the location's latitude and solar declination. - Shadow Projection:
We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle. - Minimum Spacing:
We add the shadow length to the horizontal space occupied by tilted panels.
This approach ensures maximum space efficiency while avoiding shading during critical times, as the Winter solstice represents the worst-case scenario for shadow length.
Topography for solar PV around Mosta, Malta
Mosta is located on a plateau and has rolling hills. The area surrounding Mosta is generally flat and open, making it well-suited for large-scale solar PV installations. Areas that are most suitable for large-scale solar PV include open fields, parking lots, rooftops, and other flat surfaces with direct access to sunlight.
Malta solar PV Stats as a country
Malta ranks 73rd in the world for cumulative solar PV capacity, with 196 total MW's of solar PV installed. This means that 6.50% of Malta's total energy as a country comes from solar PV (that's 12th in the world). Each year Malta is generating 373 Watts from solar PV per capita (Malta ranks 8th in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in Malta?
Yes, there are incentives for businesses wanting to install solar energy in Malta. The government offers a number of financial incentives and grants to encourage businesses to invest in renewable energy sources such as solar power. These include the Renewable Energy Investment Scheme (REIS), which provides up to €50,000 per project for eligible investments in renewable energy technologies; the Solar Photovoltaic Self-Consumption Scheme (SPVSCS), which provides a one-off grant of up to €20,000 per kWp installed; and the Feed-in Tariff (FiT) scheme, which pays businesses for any excess electricity generated from their solar installations that is fed back into the grid.
