Solar PV Analysis of Guam Government House, Guam
The location at Guam Government House, Guam is generally very good for generating energy using solar panels throughout the year. This is because it's located in the tropics where sunlight is fairly consistent most of the time.
In simple terms, let’s look at how much electricity can be produced from each kilowatt (kW) of installed solar power during different times of the year: In summer, you can expect to get about 6.14 kilowatt-hours (kWh) per day; in autumn it's about 5.45 kWh/day; in winter it's around 5.89 kWh/day and in spring you get approximately 7.25 kWh/day.
So, looking at these numbers, spring seems to be the best time for generating solar energy at this location because that’s when your panels will produce the most electricity per day.
Now regarding installation: To make sure your solar panels are as productive as possible all-year-round here, they should ideally be tilted towards south with an angle of about 12 degrees.
However, there might be a few things that could affect how well your solar panels work here:
Firstly, since Guam experiences both wet and dry seasons instead of traditional four seasons like many other places do – heavy rainfall or storms during wet season may temporarily reduce sunlight exposure which means less power generation during those periods.
Secondly though not common but typhoons could potentially damage or misalign your panel setup if they hit directly - so proper securing and regular maintenance checks would help prevent such issues.
Lastly due to its tropical climate - dust accumulation on panel surfaces could also slightly impact their efficiency over time – so regular cleaning would help maintain optimal performance levels too.
Overall though - considering its consistent sunshine hours across most part of year along with appropriate measures taken into account while installing & maintaining them; Solar PV system should work quite effectively for energy production at this location throughout entire year!
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 6 locations across Guam. 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 Guam Government House
Seasonal solar PV output for Latitude: 13.5682, Longitude: 144.8823 (Guam Government House, Guam), 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 12° South in Guam Government House, Guam
To maximize your solar PV system's energy output in Guam Government House, Guam (Lat/Long 13.5682, 144.8823) throughout the year, you should tilt your panels at an angle of 12° 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 Guam Government House, Guam
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 Guam Government House, Guam. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 12° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 3° North in Summer | 20° South in Autumn | 29° South in Winter | 7° 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 Guam Government House, Guam
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 Guam Government House, Guam.
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 Guam Government House, Guam
The topography around Guam Government House is characterized by coastal plains, with some hills and low mountainous areas. The region is largely urbanized with the city of Agana Heights being nearby.
As for large-scale solar PV installations, flat open spaces are usually ideal as they offer maximum exposure to sunlight without obstruction or shading from surrounding features such as trees or buildings. Given this, the coastal plains could be suitable if there's enough open space available.
However, it should also be noted that Guam experiences a high frequency of typhoons annually so any solar installation would need to be designed to withstand such conditions.
Another potential area could be unused military land (provided permissions and agreements can be obtained), considering the significant presence of U.S military bases on the island. These areas tend to have wide-open spaces which might prove useful for setting up large scale solar farms.
In addition, rooftops in urban areas like Hagåtña (where Government House is located) can also potentially accommodate smaller-scale distributed solar panels installations which collectively could make a significant contribution towards renewable energy generation on the island.
It's important though that any proposed site undergoes a detailed feasibility study including factors like local climate conditions (amount of annual sunshine hours), land availability and use restrictions, environmental impacts etc., before deciding on its suitability for large scale solar PV installation.
