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.

    Solar-powered TV: the TV is powered by solar and solar battery, of cause the tv must have battery built-in, or have battery partner, at first, the TV must be low power consumption TV(solar tv), then, people need have solar panel, mostly 30watts panel is enough, then, the TV must have battery partner or built-in battery. when the panel charges the battery, the battery can power the TV.

We continue to see strong growth in the sales of off-grid solar lighting products. Global sales have reached 4.11 million, with a standalone capacity of 40.88 MW worldwide.
The vast majority of these are cash sales, accounting for 3.10 million 76% of global sales) with an overall value of $85.34 million. These typically smaller products generate steady cash revenues, as they are predominantly sold in full in a single cash transaction.
As Figure 5 shows, PAYGo has reached its greatest volumes ever recorded in this reporting round,
at 1 million units with a value of $216.85 million, accounting for 24% of global sales volumes. This
is PAYGo’s highest market value, driven by sales of larger products. However,the value forthe reported PAYGo products is not yet realized in
full as our calculation is the market value, based on the expected amount to be received once the product has been paid in full by the customer. There are of course a variety of factors that can lead to this full value not always being realized and this variability around repayment in full is embedded in the pricing of products as part of the PAYGo sales model.
Globally, both cash and PAYGo sales volumes increased by 5% compared to the second half of 2018, although we see the two segments as having different trajectories in different geographies because they are driven by different categories
of products. Therefore, the two are not expected to be as aligned in future reporting rounds. Moreover, there has been a significant increase in Megawatts of 26% compared to the last reporting round, with the boost in sales largely driven by the overall increase in sales of solar home systems (SHS).
Portable Lanterns
The first half of 2019 saw 2.83 million portable lanterns sold globally, accounting for 69% of total sales worldwide. The majority of these were sold on cash basis, though an increasing amount of solar lanterns with mobile charging were sold through PAYGo channels, more than doubling from 7% in the second half of 2018 to 15% in the first half of 2019.
Larger and brighter solar lanterns capable of charging mobile phones (with an indicative wattage of 1.5-2.999 Wp) remain the bestseller
in terms of volume across all product categories. These solar lanterns make up around 37% of all product categories' global sales volumes for this reporting period, at 1.5 million units. With a dollar value of $45.8 million, this category represents 54% of the global cash sales value and 11% of the newly installed capacity at around 4.5MW.
Globally, the second best-performing category for sales volumes is the solar lantern without mobile charging (with an indicative wattage of 0-1.4999 Wp). 1.3 million of these solar lanterns were sold worldwide, representing around 30% of the
total sales volumes. The value of these products, however, accountsforonly11%ofthetotalat$9.5 million and only 1% of the total newly installed capacity at 0.49 MW. This is due to the lower retail price and the smaller panel sizes of the products in this category.
Between the two portable lantern categories, different trends appear. There is a 20% increase in sales for lanterns without mobile charging. This is mostly due to bulk purchases happening in Sub- Saharan Africa, especially in West and Central Africa. The reasons are varied, but historically the size of these orders is often significant and highly variable from one reporting round to the next. This can cause significant fluctuations in overall sales volumes.
Conversely, there is a 10% sales decrease for lanterns with mobile charging. This could indicate a possible seasonal pattern when looking at Figure 3, where usually the first half of the year sees less strong sales than the second half. However, this decrease could have been much more substantial had there not been large bulk purchases in the Middle East and North Africa (MENA) region for humanitarian purposes.

Multi-light Systems
A total of 600,000 multi-light system units were sold in the first half of 2019, accounting for 15% of the global total and installing a total capacity of 3.92 MW. 57% were sold through PAYGo channels. Historically, the majority of these systems were sold on PAYGo, however the increase of cash sales decreased PAYGo’s share to 57% in the first half
of 2019 from the 70% recorded in the second half of 2018. The cash value of total sales was $10.5 million, and the PAYGo sales value standing at $33.3 million.
Multi-light systems observe stable sales, confirming the importance of this product category which offers Tier 1 level of modern energy access to a full household. If the outlier in the reporting round of July-December 2017 - caused by a single bulk purchase - is removed, the segment then proves to be stable with sales of around 600,000 units per reporting round.
In general, it is difficult to trace a trajectory for multi-light systems. Trends in this category have to be observed in close connection with sales of SHS, due to the similarities in the level of service they provide and the increased cost competitiveness
of SHS products in the 11-20 and 21-49 Wp range. It may be that those segments will see strong competition in the coming rounds.
Solar Home Systems (SHS)
SHS - consisting of larger, higher-cost products
- recorded the highest percentage growth of
all segments in this reporting round, with a 40% increase compared to the second half of 2018 and exceeded the sales volumes of multi-light systems for the first time. This continues the great growth reported in the last round.
A total of 680,000 units were sold across the 4 categories, installing 31.88 MW and accounting for a PAYGo value of $177.5 million and a cash value
of $19.5 million. This segment saw a significant increase in the percentage of global sales, now representing 17% of the global total. This increase is in part due to the increasing number of customers using SHS to power appliances.
For solar home systems, PAYGo is the most popular method of payment, due to the larger product and higher pricing. PAYGo represents 76% of all SHS
sales. Only in the 100+Wp segment, there is a large majority of systems purchased via cash sales. It may be that these products are sold as backup systems for relatively wealthy customers, who
may not require the same level of financing as the average off-grid household. It is also possible that they are included in government financing schemes, especially in the East Asia and Pacific region.
The top-selling segment of this category is not
yet firmly in place, and shifts in each reporting round. For the first half of 2019, the top seller is
the 21-49Wp category with over 240,000 units sold, seeing a 48% increase compared to the last reporting round. Given that this is the first segment capable of powering TVs, the increase in sales is strongly connected with the customer demand
for this entertainment appliance. The second-best performing category is the 50-100Wp one, which almost reaches 200,000 units for the first time ever and records the sharpest percentage growth: a 147% increase compared to the previous round of reporting. The 11-20 Wp category products currently sit in third place, with sales similar to the last reporting round of 170,000 units. This is a good sign given that the volumes reported in the second half of 2018 were record-breaking for the category. Sales in the 100+ Wp category are also stable, with volumes clocking in at around 60,000 units.
As mentioned in the previous paragraph, it is possible that we will continue seeing increased sales in SHS segments, as customers opt for these systems to provide lighting and to power appliances such as fans and TVs.
