SOLAR TV SYSTEM

• Performance
– Gains in LED efficacy have offered the largest opportunity for performance and price improvements for solar TV
– Appliance efficiency is similarly important for solar home systems, although the effect is not as dramatic
• Durability
– The transition to lithium batteries (especially LiFePO4) is a key factor for improved
– durability for small products, and these batteries are used increasingly in larger products
• Affordability and Productive Applications
– Innovation in PAYG technology has expanded access through improved affordability – PAYG technology can also be used to expand access to productive applications
• Longevity
– Aftersales service (warranty, repairs, etc.) plays a key role in product longevity; more innovation is needed in this area

Note: The solar operating efficiency is the ratio between the actual amount of solar electricity generated by the module and the maximum that could be generated with an optimal control scheme.

This establishes methods to measure the performance, quality, and durability of televisions (TVs) for use in off-grid applications (e.g. standalone solar home system, mini-grid).
The following test conditions are defined for the evaluation of product suitability for use in off-grid applications:
 Nominal conditions;
 Voltage fluctuation conditions, which simulate performance during over-voltage and under-
voltage conditions.
 Harsh environment exposure conditions, which simulate exposure to high temperature and humidity environments. Procedures are adopted from IEC 60068-2-78: Environmental testing – Part 2-78: Tests – Test Cab: Damp heat, steady state (2012).
The following test procedures are then defined for the evaluation of product performance under the above test conditions:

The following test procedures are then defined for the evaluation of product performance under the above test conditions:
 A procedure for measuring on mode power consumption adapted from IEC 62087 Ed 3.0: Methods of measurement for the power consumption of audio, video and related equipment (2011).
 A procedure for measuring standby mode power consumption adapted from IEC 62301 Ed 2.0: Household electrical appliances – Measurement of standby power (2011).
 A procedure for measuring screen luminance adapted from the ENERGY STAR® Program Requirements Product Specification for Televisions Test Method (2011)1.
 A procedure for evaluating physical ingress protection adapted from IEC 62257-9-5:2013: Recommendations for small renewable energy and hybrid systems for rural electrification: Integrated system – Selection of stand-alone lighting kits for rural electrification.
 A procedure for measuring viewing angle adapted from IEC 60107-7:1997: Methods of measurement on receivers for television - Part 7: HDTV displays.
