Technical Standards For Solar Dryer and solar Cooker

Alternative Energy Promotion Center National Rural & Renewable Energy Programme Jan 2013

Background

Alternative Energy Promotion Centre (AEPC) is an apex institution promoting Renewable Energy Technologies (RETs) in rural Nepal. Presently, AEPC has been implementing National Rural and Renewable Energy Programme (NRREP) supported by Danida, Norad, KNV, Renewable Energy for Livelihood (RERL former Rural Energy Development Program) supported by World Bank and UNDP, Biogas Support Program (BSP) supported by SNV Nepal and KfW. AEPC works closely with various INGOs, NGOs, GOs and private sector in order to implement various programs and projects.

National Rural and Renewable Energy program has just been started from July 16, 2012. This program envisages installation of 7,500 solar thermal systems in next five years. Understanding the local needs, AEPC / NRREP is committed towards promotion of the solar thermal technology at domestic and industrial scale. To assure the quality and reliability of the products the organization is progressive in developing the technical standards. The technical standards will be paramount to benchmark the products which will be disseminated under the subsidy poilicy. 

1. Definition

Solar thermal energy: Solar thermal energy is innovative technologies for harnessing solar energy for heat.

Solar Dryer: Solar Dryer is a device that facilitates the dehydration of the matter by passing hot air in direct contact or pre-heated air through natural or forced circulation. The air is heated by solar energy.

Domestic scale sofar dryer is defined as with effective drying area of 3ft² to 20ft²

Medium scale solar dryer Is defined as with effective drying area of 21 to 85ft²

Large scale solar dryer Is defined as with effective drying area above 85ft²

Solar Cooker: Solar Cooker is a device that conver1s sunlight into heat fo 

Parabolic solar cooker: A reflective mirror of polished glass, metal or metahzed film is used to concentrate light and heat from the sun into a small cooking area. making the energy more cone ntrated and increasing its heating power.

The minimum technical standards will provide the benchmark criteria for solar cooking and dryer specified under the government subsidy policy. This document will be effective from Jan 2013 and will remain valid till a new rsion formally replaces it.

3 Minimum technical standards for solar dryer and solar cooker under the government subsidy Policy

3.1 Solar Dryer

a) Domestic scale restrict insect and minimize debris.

b) Medium Scale and Large Scale

Note -Solar drying technology not covered by the standards while valid within the government subsidy mechanism would need to provide national or international recognized 3rd party certificate verification from ETS

2 Domestic Solar Cooker

a) Parabolic Disc

Note - SoJar drying technology not covered by the standards while valid within the government subsidy mechanism - would need to provide nationial or international recognized 3rd party certificate verification from ETS
