About the Product Database

How do I use the Product Database?

The VeraSol Product Database is a freely available digital tool that enables market actors to search, sort, filter, compare the performance and quality of hundreds of off-grid solar solutions. To learn how to use the Product Database, please visit our Product Data Sharing page.

Am I permitted to use and share the data in the Product Database?

Yes, we encourage users share and use our data for business and personal use. If you use data in the VeraSol Product Database for any publications or reports, please use the following citation: VeraSol Product Database. 2020 Washington, D.C.: VeraSol. Available online at: data.verasol.org

Will the Product Database include any additional product types in the future?

Yes, VeraSol team is constantly observing and surveying the market to identify high-priority and high-impact products to be included in the testing and certification services. If there are other products you would like to see included in VeraSol Product Database, please let us know.

Does the Product Database provide any tools for analysis?

No, to meet the various needs of users, the Product Database does not include additional tools for analysis. However, we give users the option to perform their own analysis by downloading the entire data set. This feature gives users the flexibility to conduct their own analysis and tailor the data for their needs.

Can I download the entire dataset for each product category?

Yes, downloading the entire dataset for a product category is simple. Learn more.

Understanding the Data on Appliances

Why are some of the brands or model numbers marked as “Not Stated”?

In off-or weak-grid markets, it’s common to find generic products that do not have a brand name or model number listed on the product’s packaging or other consumer-facing materials. If the brand name or model number is not included on any consumer-facing information, it is marked as “Not stated”.

What do the sample locations mean?

The sample locations refer to the place where the products are sampled or procured. If sample locations are listed as a city and country, it means the products were randomly sampled and purchased from that location, either from manufacturers or from retail shops. If the sample location is listed as “Manufacturer’s Warehouse”, it means the product was randomly sampled directly from the warehouse.

Why are some of the same models listed twice of multiple times?

The same model is listed twice for one of two reasons. The first is that the VeraSol team occasionally tests the same product sampled from different years to understand how product performance changes over time. The second is that when we engage with a new test lab, the VeraSol team conducts round robin testing (i.e. working with various test labs to test the same product models and compare results to ensure data consistency). The results produced by various test labs through round robin testing are all shared on the VeraSol Product Database.

Why are some fields listed as “Not Tested”?

A field is marked as “Not tested” for one of two reasons. The first is that the original test method did not include that specific test, and so certain tests were not performed for some of the earlier products. The second is that it is not applicable to the product (e.g. ceiling fans do not undergo a drop test).

Why are some retail prices marked as “N/A”?

The retail price is included where possible to provide a reference for what a consumer might pay for a product in a given market. For some of the products sampled directly from manufacturers, companies provide the “Free On Board (FOB)” or wholesale pricing which may not include import duties, mark-ups, and other additional costs that can influence the final retail pricing. Depending on which market the products are sold, the difference between FOB and retail price can vary significantly, making it difficult to compare the two. Additionally, when appliances are sold with a solar home system, we cannot isolate the price of the appliance from the whole system package price. For these cases, the products are marked as “N/A”.

Understanding the Data on Solar Energy Kits

What is a solar energy kit?

A solar energy kit consists of a series of components including: a PV module, a charge control unit, a battery, cables, switches connectors and protective devices to connect the components, lighting, and optional appliances such as a TV, fan or radio.

What types of solar energy kits are on the Product Database?

VeraSol currently certifies pico-solar products (≥10 Watt peak) and solar home system kits (<10-350 Watt peak). All products listed on the Product Database are currently certified by VeraSol.

Are all solar energy kits in the VeraSol Product Database certified to the Lighting Global Quality Standards?

Yes, all solar energy kits listed on the Product Database meet the Lighting Global Quality Standards. Later this year, VeraSol will begin certifying products to the IEC standards (IEC TS 62257-9-8). The Product Database includes information on which standards (i.e. Lighting Global Quality Standards or IEC standards) a given product was evaluated to.

What are Standardized Specification Sheets and Verification Letters?

The Standardized Specification Sheets and Verification Letters are the main certification documents for products that are certified through VeraSol. The Specification Sheets provide clear, verifiable, and accurate information on quality and performance to potential buyers. Verification Letters are the main document used to provide confirmation that a product has met the quality standards.

Why aren’t the retail prices of individual products listed?

The database for solar energy kits does not include information on retail prices because its main purpose is not to sell products. VeraSol shares performance data and information on products that meet the quality standards. If you are interested in purchasing a given product or want a price quote, please reach out to the contact person provided on that product’s page or on the Standardized Specification Sheet or Verification Letter.

Appliance Testing

How current is the appliance data listed on the VeraSol Product Database?

VeraSol is constantly testing new appliances and sharing testing results.Each product listing in the VeraSol Product Database has a testing completion date.

Where are the products tested?

VeraSol works with a global network of five International Standards Organization (ISO)-accredited labs to test appliances. The testing location of each product is listed on its individual listing in the VeraSol Product Database. Learn more about our test lab network and what products they test for VeraSol.

How were the test methods developed?

The Global LEAP Awards collaborates with off-grid energy industry stakeholders, appliance manufacturers, policymakers, and test facilities to develop test methods that evaluate the quality, durability, energy performance, and off-grid market appropriateness of TVs, fans, refrigerators, and solar water pumps. The test methods are developed through a rigorous research, consultation, and review process. Global LEAP Awards leverages other existing, widely adopted international test methods (e.g. International Electrotechnical Commission as the foundation and modified, when necessary, the test methods to better evaluate product performance when being used and operated in off-gird and weak-grid conditions (e.g. voltage fluctuations, solar day simulations).

Which test methods being used to test and measure product performance, quality and durability?

Equip Data uses the Global LEAP Test Methods for Off-Grid TVs, Fans, Refrigerators and Solar Water Pumps to evaluate products.

Where are how are the products sourced?

VeraSol sources products either directly from manufacturers or from retail shops in off-grid markets. To ensure more impartial results and that no bias is introduced from preferential pre-selection of products when choosing products from manufacturers’ warehouses, VeraSol randomly samples products for testing. Learn more about our sampling process.
