What You'll Learn
Solar power is available at higher altitudes
Photovoltaic (PV) cells, commonly found in solar panels, can convert sunlight directly into electricity through the photovoltaic effect. Technological advancements have improved the efficiency of PV panels at higher altitudes, and they are now a viable source of electricity in regions like Everest Base Camp. The increased availability of solar power at high altitudes has several benefits, including reduced reliance on traditional energy sources and improved access to electricity in remote areas.
Previous research has shown that solar energy harvesting at high altitudes is more effective than at sea level. An installation in the Swiss Alps, at an elevation of 1,800 meters, demonstrated a 50% increase in efficiency compared to sea-level panels. This efficiency gain is attributed to the reduced dispersion of radiation and the increased direct radiation at higher altitudes.
The use of solar panels at high altitudes also has implications for powering countries far from the equator during the winter months. Research by Dr. Annelen Kahl of the Ecole Polytechnique Federale de Lausanne suggests that properly angled panels at high altitudes can significantly increase electricity generation during the winter. This is particularly relevant for countries like Switzerland, where electricity demand is typically higher in winter.
Additionally, solar power at high altitudes can be a cost-effective solution. Solar energy is often the cheapest way to generate electricity during daylight hours, and advancements in energy storage make it increasingly feasible for nighttime use as well. However, there are still challenges in storing electricity for extended periods, such as during the winter months when daylight hours are shorter.

Power banks and solar chargers are recommended
While electricity is available at Everest Base Camp, it is recommended that trekkers carry power banks and solar chargers to avoid any issues related to charging their devices. This is because, as you go higher in elevation, many of the teahouses and guest houses run on solar power only, and electricity is limited. In some cases, power may only be available from 6 pm to 8:30 pm, or until the power runs out. Charging devices at these accommodations can be expensive, with prices ranging from 150 to 450 rupees per hour.
Solar power is an excellent alternative source of electricity for trekkers, as it can be used in remote lodges at higher altitudes, depending on the weather. Sunlight is widely used by trekkers in remote areas to recharge their devices, and portable solar chargers are now readily available for purchase. Carrying a power bank is also a convenient option, allowing trekkers to avoid the hassle and cost of charging at accommodations.
Additionally, it is important to note that the cold weather can drain battery charge, so it is recommended to keep extra batteries warm. This can be done by storing them in an insulated pouch or pocket close to your body, ensuring they maintain their warmth and charge.
Overall, by relying on power banks and solar chargers, trekkers can ensure their devices remain charged throughout their journey to Everest Base Camp, without having to depend on the limited and costly electricity available at higher elevations.
