Google says a three-year collaboration with Ignite Energy Access has developed mapping, routing and supply-chain tools for off-grid solar distribution in sub-Saharan Africa. The company estimates the partnership enabled more than 160,000 tonnes of CO2-equivalent emissions reductions in the first half of 2026, linked to 3.7 million solar devices delivered since 2023.
Google says its three-year partnership with Ignite Energy Access has helped develop mapping and logistics tools for distributing off-grid solar in sub-Saharan Africa, and estimates the work enabled more than 160,000 tonnes of CO2-equivalent emissions reductions in the first half of 2026. The company links the estimate to 3.7 million solar devices delivered across the region since 2023; the figures and impact assessment are Google’s, rather than an independently verified evaluation described in the report.
The collaboration, undertaken through Google’s Startups for Sustainable Development program, brought Ignite together with Google researchers, engineers and data specialists over three years. Google says the teams held more than 100 advisory sessions to address barriers to reaching households that lack formal addresses and are separated by rough or unmapped routes. Ignite describes its ambition as connecting 100 million people across Africa to electricity by 2030.
To identify potential customers and plan deliveries, the teams combined satellite imagery, Google’s Open Buildings dataset and routing algorithms. Google also says it is developing geospatial models to identify rural paths and include them in routing plans. Its operations-research models are being used to evaluate warehouse and local mini-hub locations, taking into account factors such as transport costs, vehicle capacity, routes and inventory expenses.
The report also describes work to locate existing small solar installations from satellite imagery. Because a rooftop panel can occupy only about one pixel in standard imagery, the teams are developing computer-vision models using Gemini for Science and drone images supplied by Ignite. Google says the models are being tested for precision and recall; it does not provide performance results or say the system is already deployed at scale.
Reaching Homes Beyond Mapped Roads
Off-grid solar distribution depends not only on equipment but also on finding households and getting devices to them. Tools that improve household identification, rural routing and stock planning could help providers serve communities where conventional address and road data are limited. Better maps of existing installations could also help operators identify areas that remain underserved and decide where to direct future deployments.
The scale of the need is substantial, according to the report: Google says more than 600 million people in sub-Saharan Africa lack electricity. That figure frames the potential relevance of last-mile planning, but the partnership’s reported device deliveries do not establish how many people gained reliable electricity, how long systems remain in use, or what share of the regional access gap has been addressed.
The next phase concerns energy uses beyond lighting. Google says it and Ignite are modeling community-level microgrids for electric cooking, which requires more power than an individual rooftop solar kit can provide. If workable, such systems could address household energy needs that small solar devices alone cannot meet. The report gives no timetable or deployment commitments for the cooking work.

Three Years of Mapping and Delivery Work
The report’s starting point is the difficulty of serving dispersed rural households. Google says many homes are absent from standard maps, while routes between communities may consist of unmapped dirt tracks and difficult terrain. Even after solar devices are delivered, identifying small rooftop systems from orbit presents another data challenge because the panels are barely distinguishable in typical satellite images.
Google presents the partnership as a way to apply its technical expertise to an energy-access provider’s field operations. The work covers both the physical supply chain—where to place warehouses and mini-hubs, and how to plan deliveries—and the data needed to locate households and installations. The company says the effort has produced a repeatable approach that could be useful beyond this partnership, but the report does not identify other organizations currently using the tools.
Google’s emissions estimate is tied to devices delivered since 2023, while the stated reduction figure covers the first half of 2026. The report says those milestones contribute toward Google’s aspiration to help partners collectively reduce one gigaton of carbon-equivalent emissions annually by 2030. That corporate goal is not a measured outcome of this project alone.
““Across sub-Saharan Africa, nearly half the continent’s population — over 600 million people — live without electricity.””

How Impact Will Be Verified
The report does not provide the methodology behind the 160,000-tonne CO2e estimate, including its assumptions, comparison baseline or independent review. It also does not specify how many households received devices, how many systems are operating, or how the reported deliveries translate into sustained electricity access. Google describes the satellite-detection models as under development and provides no precision or recall figures, deployment date or coverage area. The timing, financing and expected capacity of the proposed microgrids for electric cooking are also not stated.
Testing Models and Microgrid Plans
Google says researchers are continuing to test computer-vision model variations against drone imagery provided by Ignite, with the aim of improving detection of small solar installations. The partners are also modeling community-scale microgrids for clean electric cooking. The report does not set a launch date or give details on where those systems might be built.
Further evidence of the project’s reach will depend on whether the mapping and logistics tools move from development and planning into sustained field use, and on more detail about how emissions estimates are calculated. Google says its 2030 emissions aspiration is a collective partner goal; the report does not announce a new project deadline or a quantified target for Ignite’s next phase.
Key Questions
What did Google and Ignite Energy Access report?
Google reported on a three-year collaboration to improve mapping, routing and supply-chain planning for off-grid solar distribution. It estimates the partnership enabled more than 160,000 tonnes of CO2e reductions in the first half of 2026.
How many solar devices were delivered?
Google says 3.7 million solar devices were delivered across the region since 2023. The report does not give a household count or say how many devices are currently operating.
Is the emissions figure independently verified?
The report presents it as Google’s estimate. It does not describe an independent audit or provide the calculation method and comparison baseline.
What is planned beyond household solar kits?
Google says the partners are modeling community-level microgrids that could supply enough power for electric cooking. The report gives no deployment timetable or confirmed project locations.
