"Solar electricity is an eco-friendly technology and the most viable alternative energy source available here," says Moon Pradhan of Gham Power. "Loadshedding has forced people to look into solar as a convenient and safe power option." In operation since February this year, the company has already installed over 70 PV solar systems.

The costs also come down if low-wattage electronic appliances are installed. "We need to be conscious about power consumption when we purchase electronic goods," says Manish Bajracharya of Lotus Energy. "It can easily cut down on our energy requirements and bills."

Another plus point is that the investment in the system pays for itself in the long run. "Sunlight is abundant and free," explains KR Khanal of Ultra Group. "And unlike other energy options, the operating costs of a solar system are minimal." Most PVsolar panels come with a 25-year warranty, and the only maintenance they require is cleaning. Batteries require a change of distilled water every three to six months.

Surendra Mathema of Tahachal has a 200W solar backup in his house and is one satisfied customer. "I also use a solar cooker, which makes my cooking gas last longer, " says Mathema. He now has another 500W of solar capacity and is exploring the possibility of joining it up to the main grid.

Use of PV solar modules for electricity started in Nepal with rural electrification projects in areas that did not have access to the main hydroelectric grids. "A solar lighting system does not require huge infrastructure, can be installed in a day and even a small system can power the energy needs of a rural household," says Yug Tamrakar of Solar Electricity. According to the Alternative Energy Promotion Centre, more than 225,000 PV solar systems have been installed in rural households, a total of 8MW of electricity. The use of solar in rural areas has been boosted by a subsidy for rural solar projects that ranges from Rs 5,000-Rs 10,000.
