During long mountaineering expeditions, we use specialised Solar Panels for electricity consumption. We have a 6 Panel Solar System which has the solar capacity of 90 watts. Perfect for camping and trekking, these Solar Panels are incredibly durable, lightweight, portable, extremely powerful and designed to standup to the toughest weather conditions.
Solar energy is cheap and very easy to change into electric energy. You just need to have a good spot to mount the solar panel. To ensure that the panel receives the most possible sunlight, it should be mounted on a south-facing slope unshaded by any object or trees. The solar panels will convert the light energy obtained from the sun directly into electric energy. This electricity produced is in DC format or Direct Current. The solar panels are connected to a 12 volt battery, through which direct current is acquired and is used to light DC bulbs. One DC port can light around 4 DC bulbs. You can charge around 5 batteries at a time but the more batteries you charge, the more time is consumed for charging all the batteries. After the batteries are charged, the DC is stored directly in the storage batteries, the charge remaining stored when not in use. A Solar Controller can be used to check the charge rate (fully charged, etc.) in the battery.
Direct Current can only light DC bulbs but cannot be used for other applications. Hence, Alternating Current (AC) is needed to operate computers, heaters, to charge laptops, mobile phones, satellite phones, etc. In order to obtain AC, an inverter is used. An inverter is an electronic circuit that converts direct current (DC) into alternating current (AC). This solar panel is multifunctional, as both DC and AC can be acquired at the same time, for multipurpose use. This is a very easy technique, known by every climbing Sherpa.
