Our Approach to
Social Impact
Measurement
T
To achieve our ambitious social impact goals, d.light employs a rigorous data-driven approach to measure impact across our key impact metrics. We use sales data, customer feedback, and ongoing product evaluation in the field to provide a comprehensive picture of how access to energy transforms the lives of our customers.
For solar products, our impact numbers are calculated using GOGLA standardized impact metrics. For non-solar products or impact metrics not defined by GOGLA, we adapt the methodology. Our impact metrics include:

Lives Transformed: All products we sell are designed to create a transformation in the lives of our customers. We assume that even if a product is primarily used by one person in a household, the entire household benefits in some way. We apply household size and discount factors outlined by the GOGLA methodology but count multiple transformations for one household. For example, if a family purchases a solar lantern and later purchases a clean cook stove and a pay-go solar home system, we count their lives being transformed three separate times.
CO₂ Offset: We calculate this based on the GOGLA methodology for solar products and use third party carbon credit methodologies for products outside of this category (such as for clean cook stoves).
GWH generated from renewable energy source: This metric applies to solar products and is calculated using the GOGLA methodology.
$s saved from Energy Related Expenses: This metric applies to solar products and is calculated using the GOGLA methodology.
School-aged children reached with solar lighting: We calculate this based on the average number of school-aged children in households. This metric only applies to solar products we sell with a lighting component.
Productive Hours created: This metric applies to solar products and is calculated using the GOGLA methodology.

At d.light, we are committed to improving the lives of our customers and to making a positive impact in the communities we serve. By measuring our impact through these metrics, we ensure that we are on track to achieve our social impact goals and that we continue to make a difference in the lives of our customers.
