SMALL-SCALE VOLUNTARY PROGRAMME ACTIVITY DESIGN DOCUMENT FORM (Voluntary-SSC-VPA-DD) - Version 01 NAME /TITLE OF THE VPoA: Solar Lighting in Rural Ethiopia VPoA This template shall not be altered. It shall be completed without modifying/adding headings or logo, format or font. page 20 According to small scale methodology AMS I.A (version 14), monitoring shall consist of an annual check of all systems or a sample thereof to ensure that they are still operating. In this case, each VPA will be verified by testing a representative sample of SHSs. The CME has opted to implement a verification system for the DOE that will individually verify each VPA (instead of sampling) in order to determine the emission reductions from the VPA. The central database managed by the CME includes data that can be directly attributed to each VPA within the VPoA, thereby allowing unambiguous determination of the emission reductions attributable to each VPA: Solar systems deployed for each household under the individual VPA as per sales records. The record includes household location and household identification number depending on system type), client’s name, system type ( ST-1,ST-2, ST.-5 or ST-10) and serial number of panel, battery and charge controller for ST-10; panel and battery, for the remaining systems, payment details, GPS data and the corresponding Solar Center under which the household is listed. Sample database for VPAs, Data collected from the Project Sample Group households of each VPA relating to the ongoing usage of project systems and operational LEDs during each monitoring period In order to ensure accuracy and completeness of the information retrieved by Solar Centers, the criteria for selecting distributors of SEF solar systems will also take into account their access and ability to accurately provide updated records of sales and customers. Sampling Plan Sampling is carried out separately for each solar system type i. In the description below i is fixed. According to the methodology AMS I.A., monitoring shall consist of annual checks of all systems or a sample thereof to ensure that they are still operating. There are 4 SHSs types sold that include different numbers of LEDs: SHS Sun Transfer 1 – 1 LED lamp SHS Sun Transfer 2 – 1 LED lamp SHS Sun Transfer 5 – 3 LED lamp SHS Sun Transfer 10 – 4 LED lamp To ensure that all SHSs are fully operational, it has to be monitored whether the total numbers of lamps in each SHS of the different types are operational. During monitoring checks, system will be differentiated by type and therefore 4 Sampling Groups will be created to account for the different types of SHSs installed. Monitoring will be conducted over the crediting period, 10 years, and with a 90/10 confidence/precision. 1 Field Measurement Objectives and Data to be collected The field measurement objective.is to identify the total number of LEDs operational based on the
SMALL-SCALE VOLUNTARY PROGRAMME ACTIVITY DESIGN DOCUMENT FORM (Voluntary-SSC-VPA-DD) - Version 01 NAME /TITLE OF THE VPoA: Solar Lighting in Rural Ethiopia VPoA number of SHSs installed. Ni,a Number of solar lamps of system type i installed in period a This template shall not be altered. It shall be completed without modifying/adding headings or logo, format or font. page 21 The samples to be checked will have the same weighted age as the total number of deployed solar systems. For example, if an equal number of system type i in the first year of use (age0-1) and second year of use (age1-2) are credited, a usage parameter is required that is weighted to be equally representative of lamp failure rates for system type i age0-1 and age1-2. The minimum total sample size is 100, with at least 30 samples for project technologies of each age being credited. Thus, if systems type i of age 1-5 are credited, the usage survey must include 30 representative samples from each age for a total of 150 samples. The resulting usage parameter will be weighted based on the proportion of systems type i in the total sales record of each age. di,a,y As the systems are installed gradually, the average number of days in the first year is set as 180 days; meanwhile, with the same reason, the average number of days in the last year is set as 180 days. All the years in between are considered at 365 days. In order to ensure that lamps are in operation for at least 180 days in the first and last year of the crediting period, the parameter is monitored by checking the implementation date, which is recorded in the central database, and interviewing the households of the selected sample groups whether the lamps have been operational since then. CFi,v,LFR Once the number of solar lamps of system type i that are operational have been identified a correction factor is applied. This factor corrects the total number of lamps of system type i by the share of these lamps of the same system type i that were found to be operational according to the sampling in the monitoring period v. The statistical error is included in this parameter (confidence level 90%). The correction factor is based on the Lamp Failure Rate. LFRi,v The LFR is the share of lamps of system type i in the 4 Sample Groups that were found not to be operational for the monitoring period v. Even though all SHSs use the same lamp type, based on the different composition of the SHSs, the estimated lifetime of lamps varies between the ST 10 and the remainder of systems. LEDs of ST 10 are estimated to have an operational lifetime of 50,000 hrs whereas LEDs of ST1, 2 and 5 are estimated to be operational for 30,000 hrs. The fraction of checked lamps according to system type which were not found to be operational is calculated by dividing the fraction of non-operational lamps of the respective system type by the total number of lamps of the same system type Ideally, every 12 months from the start of the VPA, an on-site survey of sample households shall
