More people using solar lighting system

Small solar lighting devices are becoming increasingly popular among households, particularly those from middle income groups, as they help lighten up homes with small investment during power cuts.

According to traders, sale of these devices has increased by 15 to 20 percent this year compared to last year. They expect the sales to grow further as price of these devices has dropped by 7 to 10 percent this year due to drop in import costs of solar cells. 

“This will increase the demand of solar lightning systems as people can overcome power crisis with lesser investment,” said Resham Lal Gautam, director of Clean Home´s Energy Nepal at Sano Bharyang.

Wide range of solar lightning systems like home lighting, street lighting, traffic lighting, garden lighting and mobile charging system are available in the market. 

The accessories required for solar lightening systems are imported from India and china and the companies assemble them as per the need of the customers.

“Many people are switching to solar Light Emitting Diode (LED) lights to overcome power crisis as they are affordable. This has increased the demand for these devices both in and outside the capital,” said Yug R Tamrakar, managing director of Solar Electricity Company at Bagbazar that manufactures solar photovoltaic system.

According to Tamrakar, small solar lightning systems are the best options for those who cannot afford expensive power backup solutions. 

Solar systems with capacity ranging from 2.5 watts to 20 watts are considered the best for household use. The 2.5 watt Solar Tuki System with solar panel costs Rs 2,800. It was priced Rs 3,000 last year. Similarly, solar panel of 5 watt capacity that lights 2 LED bulbs is now available at Rs 4,500 down from last year´s Rs 5,000.

Fixed solar system of 10 watt capacity costs Rs 7,300, down from Rs 8,000 last year. Likewise, solar system of 20 watt capacity costs Rs 13,500. Last year, it was priced at Rs 14,500.

Fixed solar system of 10 watt can light 4 LED bulbs for five hours while system of 20 watt can light 7 to 8 LED bulbs for up to 10 hours. 
The companies provide five-year warranty on solar panels and one-year warranty on LED lights and battery.
