Solar PV Analysis of Tarxien, Malta
The location at Tarxien, Ta' Xbiex, Malta is generally good for generating solar energy throughout the year, but some seasons are much better than others. The highest amount of electricity can be generated in summer with an average of 7.96 kilowatt-hours per day for each kilowatt of installed solar power. This is followed by spring with an average of 6.65 kilowatt-hours per day. Autumn and winter produce less electricity due to shorter daylight hours and weaker sunlight, averaging at 4.21 and 3.32 kilowatt-hours per day respectively.
To maximize the total yearly production from solar panels in this location, it's best to tilt them at an angle facing 31 degrees South if they're installed as a fixed system.
However, there may be local factors that could affect solar production here such as weather conditions like heavy rain or cloud cover which can limit sunlight exposure on the panels; environmental factors like dust or bird droppings that could accumulate on the surface of the panels reducing their efficiency; topography issues like tall buildings or trees casting shadows onto your panels; and other local factors like regulations about where you can install your panels.
To counter these potential problems, regular cleaning and maintenance should be done to keep the panel surfaces clean to ensure maximum sun exposure. If shadowing is a problem due to surrounding buildings or trees, consider installing the panels in a different location if possible or using tracking systems that move with the sun during daytime for optimal sun exposure. It's also important to check local regulations before installation so you don't run into any legal issues later on.
In conclusion, while there might be some challenges related to weather conditions and local surroundings affecting sunlight exposure on your solar PV system in Tarxien, Ta' Xbiex, Malta; these can often be managed effectively through proper planning and maintenance practices making this location generally suitable for year-round solar energy generation with higher outputs during summer and spring seasons.

Solar output per kW of installed solar PV by season in Tarxien
Seasonal solar PV output for Latitude: 35.8625, Longitude: 14.5179 (Tarxien, 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 Tarxien, Malta
To maximize your solar PV system's energy output in Tarxien, Malta (Lat/Long 35.8625, 14.5179) 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 Tarxien, 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 Tarxien, 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 Tarxien, 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 Tarxien, 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 Tarxien, Malta
Tarxien is located in the southeastern part of Malta, which is largely characterized by low hills and terraced fields. The area has a Mediterranean climate with plenty of sunshine throughout the year, making it suitable for solar PV installations. However, its topography might present some challenges due to lack of flat open spaces.
The most suitable areas for large-scale solar PV installations would be flat rooftops of buildings or any available open land that receives ample sunlight. Rooftop solar panels are quite popular in Malta due to space constraints on the island. Another possible option could be offshore floating solar farms given the country's surrounding sea.
However, all these suggestions would need proper feasibility studies considering various factors such as cost, environmental impact, grid connection and local regulations before any implementation.
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.
