Solar PV Analysis of Luganville, Vanuatu
Luganville, Sanma, Vanuatu is a good location for generating solar energy throughout the year due to its tropical climate where sunlight is consistent most of the time. The amount of electricity that can be generated from each kilowatt of installed solar varies with the seasons: it's highest in summer at 6.50kWh per day, drops slightly in autumn to 5.19kWh per day, lowers further during winter to 4.84kWh per day, and increases again in spring to 5.92kWh per day.
The best times for solar power generation at this location are the sunnier periods of summer and spring; however, even during autumn and winter months when sunlight may be less intense or frequent, a reasonable amount of electricity can still be produced.
For a fixed panel installation here, tilting panels at an angle of 14 degrees towards North will help maximize total year-round production from the solar PV system as it would allow for optimal exposure to sunlight throughout different times of the year.
However there could be some local factors that might affect solar production such as heavy rainfall or storms especially during wet seasons which could block sunlight or damage panels. Also dust accumulation on panels can reduce their efficiency over time if not cleaned regularly.
Preventative measures include installing sturdy and weather-resistant mounting systems that can withstand harsh weather conditions; regular cleaning and maintenance schedules should also be put in place to ensure panels are kept clean and functioning optimally all through the year.
In conclusion Luganville has favorable conditions for producing substantial amounts of energy via Solar PV systems all-year round provided these potential issues are managed effectively.
Note: The Tropics are located between 23.5° North and -23.5° South of the equator.
So far, we have conducted calculations to evaluate the solar photovoltaic (PV) potential in 3 locations across Vanuatu. 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 Luganville
Seasonal solar PV output for Latitude: -15.5231, Longitude: 167.1646 (Luganville, Vanuatu), 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 14° North in Luganville, Vanuatu
To maximize your solar PV system's energy output in Luganville, Vanuatu (Lat/Long -15.5231, 167.1646) throughout the year, you should tilt your panels at an angle of 14° North 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 Luganville, Vanuatu
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 Luganville, Vanuatu. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 14° North tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 0° in Summer | 22° North in Autumn | 31° North in Winter | 9° North 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 Luganville, Vanuatu
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 Luganville, Vanuatu.
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 Luganville, Vanuatu
Luganville, the second largest city in Vanuatu, is located on the island of Espiritu Santo. The topography around Luganville consists of a mix between coastal lowlands and interior mountainous regions. The coastal areas are relatively flat with tropical rainforests and plantations while the inland areas feature rugged terrain with mountains, hills and valleys.
The best-suited areas for large-scale solar PV installations would be in the flatter coastal regions where there is less shading from mountains or dense vegetation. These locations provide more consistent sun exposure throughout the day which maximizes energy production from solar panels.
However, it's important to note that any large-scale installation would need to take into consideration local environmental factors such as rainfall (Vanuatu has a tropical climate with high rainfall), soil stability (to support infrastructure) and potential cyclone risks. Additionally, land ownership rights could also play a significant role in determining feasible locations for solar PV projects.
Ultimately, specific site assessments including detailed topographical surveys and solar irradiation studies would need to be conducted to identify most suitable sites for large scale Solar PV installations around Luganville.
