VeraSol’s robust sampling and independent, third-party testing processes ensure that the results we share in our Product Database are consistent and accurate. The appliance testing process can be broken down into four simple steps.
VeraSol conducts random sampling to eliminate preferential pre-selection bias from manufacturers or distributors. Random sampling also ensures that the test data are representative of products from commercial production. VeraSol identifies and samples products through two different channels: retail markets and manufacturers.
Retail MarketsVeraSol samples products from off-grid product retail markets to get better data on what products are available to an average off-or weak-grid consumer. On-the-ground consultants work with the VeraSol team to survey retail shops, gather product data, and identify products for testing.
ManufacturersManufacturers submit their product for testing directly to VeraSol. Once they submit a product for testing, VeraSol works with sampling agents to conduct warehouse visits and randomly select products from their existing stock for testing.
Independent laboratory testing and evaluation assess the extent to which products meet their advertised performance claims and measures the design elements that make them suitable for off-grid use. VeraSol coordinates and advises a global network of ISO-accredited test laboratories to test products. Testing is performed in accordance with the Global LEAP test methods for off-grid appliances.
Once testing has concluded, the lab shares the test results with the VeraSol team. During this time, the team reviews the results, conducts data quality control, and works with test labs to update the results as necessary. The goal of this step is to ensure the accuracy and comparability of the test results we publish.
The data is uploaded and organized into VeraSol’s interactive, easy-to-use Product Database. This open-access tool enables any user to easily access and use the product data. The VeraSol team works with market actors throughout the value chain to interpret data and conduct benchmarking.
The VeraSol Product Database is the central repository for all off-grid solar technologies from off-grid solar energy systems to productive use equipment. By sharing first-of-its-kind performance data and benchmarking, VeraSol brings much-needed transparency and consistency to the off-grid solar market. This tool helps market actors to make faster, smarter decisions about off-grid-appropriate appliances.
