Marsa, Malta, situated at coordinates 35.8771, 14.4998, offers a promising location for solar PV energy generation throughout the year. This Mediterranean island town benefits from its position in the Northern Temperate Zone, experiencing abundant sunshine and moderate temperatures.

Seasonal Solar Performance

Solar energy production in Marsa varies significantly across seasons. Summer stands out as the most productive period, with an impressive daily output of 7.97 kWh per kW of installed solar capacity. Spring follows closely, generating 6.62 kWh/day. Autumn sees a noticeable decrease to 4.16 kWh/day, while winter experiences the lowest output at 3.25 kWh/day.

Optimal Generation Periods

The most ideal times for solar energy generation in Marsa are during the summer months (June to August) and late spring (April to May). These periods offer longer daylight hours and more direct sunlight, maximizing solar panel efficiency. Even during the less productive autumn and winter months, Marsa still maintains a reasonable level of solar energy generation due to its favorable Mediterranean climate.

Panel Installation Considerations

For fixed panel installations in Marsa, the optimal tilt angle to maximize year-round solar production is 31 degrees facing South. This angle ensures the panels capture the most sunlight throughout the year, accounting for seasonal variations in the sun's position.

Environmental and Weather Factors

While Marsa generally provides excellent conditions for solar energy production, there are a few factors to consider:

• Dust and salt spray: Due to its coastal location, panels may accumulate salt deposits and dust, potentially reducing efficiency.
• Occasional strong winds: Malta can experience gusty winds, which may affect panel stability if not properly secured.

To mitigate these issues, regular cleaning of the panels is recommended to remove salt and dust buildup. Additionally, using sturdy mounting systems designed to withstand strong winds can ensure the longevity and efficiency of the solar installation. With these precautions in place, Marsa remains an excellent location for harnessing solar energy throughout the year.

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 Marsa

Seasonal solar PV output for Latitude: 35.8771, Longitude: 14.4998 (Marsa, 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 Marsa, Malta

To maximize your solar PV system's energy output in Marsa, Malta (Lat/Long 35.8771, 14.4998) 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 Marsa, 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 Marsa, 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 Marsa, 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 Marsa, Malta.

Our calculation method

1. Solar Position:
   We determine the Sun's position on the Winter solstice using the location's latitude and solar declination.
2. Shadow Projection:
   We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle.
3. 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 Marsa, Malta

The topography around Marsa, Malta, is characterized by a mix of coastal lowlands and gently rolling hills. Marsa itself is situated in a low-lying area near the Grand Harbour, with the terrain gradually rising as you move inland. The coastline in this region is relatively flat, featuring small bays and inlets that have been developed for maritime activities. As you move away from the coast, the landscape becomes more varied. To the west and southwest of Marsa, the terrain begins to undulate, with small hills and valleys creating a patchwork of agricultural land and urban development. These hills, while not particularly high, provide some elevation changes that contrast with the flatness of the coastal areas. To the north and northeast of Marsa, the land rises more noticeably, forming part of the central ridge that runs through Malta. This area is characterized by limestone plateaus and gentle slopes, offering panoramic views of the surrounding countryside and the Mediterranean Sea.

Areas Suitable for Large-Scale Solar PV

When considering locations for large-scale solar photovoltaic (PV) installations near Marsa, several factors come into play. The ideal areas would have ample sunlight exposure, relatively flat terrain, and minimal obstruction from buildings or natural features. One promising area for solar PV development would be the agricultural lands to the southwest of Marsa. These areas offer expansive, open spaces with good sun exposure and relatively flat terrain. The gentle slopes in this region could actually be advantageous, as they can be oriented to maximize solar gain. Another potential location would be the elevated plateaus to the north and northeast of Marsa. While these areas may have some topographical variations, they benefit from excellent sun exposure due to their elevation. The higher altitude also means less potential for shadowing from nearby structures or geographical features. It's worth noting that Malta's limited land area and dense population pose challenges for large-scale solar installations. Therefore, any solar PV projects would need to carefully balance energy production goals with land use considerations and environmental impact. Innovative approaches, such as integrating solar panels into existing structures or utilizing brownfield sites, might be necessary to maximize solar energy potential in this region.

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.
