Solar Energy Potential in Tsimasham, Chukha, Bhutan

Tsimasham, Chukha, located in Bhutan's northern sub-tropical region, offers promising conditions for solar PV energy generation throughout the year. The location demonstrates relatively consistent solar energy production across all seasons, with some notable variations that potential solar installers should consider. The seasonal electricity output from solar PV installations in Tsimasham shows an interesting pattern. Spring stands out as the most productive season, generating approximately 5.00 kWh per day for each kilowatt of installed capacity. Autumn follows closely with 4.58 kWh/day, while summer produces 4.50 kWh/day. Winter experiences a slight dip but still maintains a respectable 4.28 kWh/day per installed kilowatt. For those planning fixed solar panel installations in Tsimasham, Chukha, the ideal tilt angle to maximize year-round energy production is 26 degrees facing South. This specific angle has been calculated by analyzing the optimal panel orientation relative to the sun's position throughout the year, weighted by the solar potential at this location.

Environmental and Weather Considerations

Several environmental factors could potentially affect solar production in Tsimasham. The sub-tropical location means monsoon conditions may impact solar generation during certain months. Heavy rainfall and increased cloud cover during the monsoon season (typically June to September) could temporarily reduce solar efficiency despite the otherwise favorable summer conditions. Mountain shadows may also be a consideration in this Himalayan region. Depending on the exact installation site within Tsimasham, Chukha, nearby mountains could cast shadows during early morning or late afternoon hours, potentially reducing daily production time.

Preventative Measures for Optimal Production

To maximize solar energy production in Tsimasham, Chukha, several preventative measures should be considered:

• Elevate panels sufficiently to avoid snow accumulation during winter months
• Install robust mounting systems designed to withstand potential high winds in mountainous terrain
• Implement regular cleaning protocols to remove dust and debris, particularly during drier months
• Consider micro-inverter or power optimizer technology to minimize the impact of partial shading
• Conduct a detailed site survey to identify potential shadow-casting obstructions throughout different times of the year

With its consistent seasonal output and proper installation considerations, Tsimasham represents a viable location for solar PV development, offering relatively stable energy production throughout the year with spring being the optimal production period.

Solar output per kW of installed solar PV by season in Tsimasham

Seasonal solar PV output for Latitude: 27.1021, Longitude: 89.5388 (Tsimasham, Bhutan), 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 26° South in Tsimasham, Bhutan

To maximize your solar PV system's energy output in Tsimasham, Bhutan (Lat/Long 27.1021, 89.5388) throughout the year, you should tilt your panels at an angle of 26° 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 Tsimasham, Bhutan

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 Tsimasham, Bhutan. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 26° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
11° South in Summer	33° South in Autumn	43° South in Winter	21° 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 Tsimasham, Bhutan

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 Tsimasham, Bhutan.

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 Tsimasham, Bhutan

Topography of Tsimasham and Surrounding Areas

Tsimasham is situated in the southwestern part of Bhutan, nestled within the foothills of the Himalayan mountain range. The topography around Tsimasham is characterized by dramatic elevations, with the landscape consisting primarily of steep mountain slopes, deep valleys, and flowing rivers. The settlement itself sits at an elevation of approximately 1,800 meters (5,900 feet) above sea level. The terrain surrounding Tsimasham features significant variations in altitude, with nearby peaks reaching heights of over 3,000 meters. The region is part of Bhutan's Sub-Himalayan zone, where the landscape transitions from the lower foothills to the higher mountains. This creates a complex topographical profile with numerous ridges, valleys, and plateaus. The area is drained by several tributaries that eventually feed into the Raidak River (also known as the Wang Chhu in Bhutan). These waterways have carved deep gorges and valleys throughout the region, creating natural boundaries between settlements and agricultural zones. Forest cover is substantial around Tsimasham, with mixed coniferous and broadleaf forests dominating the hillsides. These forests play a crucial role in preventing soil erosion on the steep slopes that characterize the area.

Potential Areas for Solar PV Development

When considering locations for large-scale solar photovoltaic installations near Tsimasham, several topographical factors must be evaluated. The ideal areas would feature relatively flat terrain, southern exposure, minimal shading, and accessibility for construction and maintenance. The south-facing slopes of the hills surrounding Tsimasham offer promising potential for solar energy development. These areas receive more direct sunlight throughout the year compared to north-facing slopes. Particularly, the gentler slopes and small plateaus south of Tsimasham present viable options for solar installations. Several relatively flat areas exist along the valley floors near Tsimasham, particularly along the wider sections of the Wang Chhu valley. These locations offer easier construction conditions and good solar exposure, though they may require evaluation for flood risk. The higher elevation ridges approximately 5-10 kilometers south of Tsimasham feature some plateau-like areas that could accommodate larger installations. These higher elevation sites typically experience less fog and cloud cover than the valley bottoms, potentially increasing solar efficiency. Areas where deforestation has already occurred for agriculture or other development might present opportunities for solar installation without requiring additional forest clearing, aligning with Bhutan's strong environmental protection policies. It's worth noting that Bhutan's challenging topography generally limits the size of contiguous flat areas available for development. This geographical reality suggests that multiple medium-sized installations might be more feasible than single massive solar farms. The mountainous terrain also creates considerations regarding grid connectivity and accessibility for construction equipment. Any development would need to carefully consider the region's seasonal patterns, including the monsoon period which brings heavy rainfall and potential for landslides on steeper slopes. The most suitable areas would balance favorable solar exposure with geological stability and minimal environmental impact.
