Why Purchasing Solar Water Heater is a Smart Investment in Nepal?

A solar water heater in Nepal is a wise investment because of its long-term reliability, major savings on costs, and environmental advantages. Many areas have more than 300 days of sunshine a year, thus solar water heaters effectively supply hot water while lowering the need for other energy source. Although a solar water heater can save households about NPR 15,000 a year on electricity costs, the initial expense starts at about NPR 51,000. It makes Nepal cleaner by reducing CO2 emissions by roughly 1500 kg in a year, which is the same as planting 38 trees. With little maintenance, these heaters can last up to 20 years, and government grants through the Alternative Energy Promotion Center (AEPC) reduces the cost.

Reasons for purchasing Solar Water Heater in Nepal

• Maximum exposure to sunlight: The majority of regions in Nepal experiences plentiful of sunshine in a year for effective operation of solar water heater. According to, MDPI the country come across 300 Sunny days per year with 6.8 sunshine hours per day. Furthermore, SOLAR GIS maps show strong solar irradiation throughout the nation.

• The cost of hot water is higher: As claimed by NEA, the average electricity consumption in household ranges between 862-912 KWH/Year. This clearly indicates increase in use of electrical appliance including electric geysers and heat pumps. As reported by Kathmandu Post, the cost of domestic LPG gas cylinder is approximately NPR 1910 which is very expensive to use it for heating water.

• Cheaper Operational Cost: In comparison to LPG Gas and electrical appliances, the operational cost of solar water heater is cheaper in long run because after making an initial investment it only requires solar energy and regular maintenance to achieve effective operation.

• Security of energy: Irregular supply problems exist even if load-shedding is mostly gone. The majority of hot water demand is separated from the electrical system and cylinders by a solar heater.

• Incentives and Subsidies on Solar Energy: Solar technologies (mini-grids, rooftops, irrigation) are strongly promoted by government and AEPC programs. Although household subsidies differ depending on the program and year, the general direction of policy is encouraging.

• Benefits to the environment: By replacing highly demanded electricity and LPG (a fossil fuel), households reduce CO₂ emissions and improve air quality. With the growing hydropower capacity in Nepal’s grid, solar energy can also generate clean electricity for other purposes.
