The E3 Conference

Sharing Solar Energy experiences in Bhutan by JB Solar Solution

B2B initiative supported by Danida

Batec ( Danish company) & Jattu ( local company) initiated a Pilot Test project which was supported by Danida ( 2010 -2012)

Decided to Test market in practise rather than making a feasibility studyAssembly unit to be set up in Bhutan (train in

the working process involved in manufacture of solar absorbers)

ChallengesLonger pay back period ( Cheap electricity)Financial assistancesAvailability of cheaper solar heating systemsPoor Plumbing solutionsPoor energy efficient buildingsLack of Energy saving consciousness ( Mind

set)

OpportunitiesEnergy savings ( energy efficient

constructions)Potential for more revenue from export of

ElectricityHarnessing Free EnergyPromoting good Plumbing practisesIncrease in domestic revenueEmployment & skilled manpower

Bhutan is blessed with natural resources

White petrol ( Hydro potential)Green Petrol ( Renewable forest resources)Rich flora & Fauna, culture ( Tourism)Sunny Winters ( Rich in solar energy)
