A new report highlights a critical opportunity for the off-grid solar industry to extend the lifespan of solar products in rural and remote communities through enhanced repair initiatives.
Published by researchers from UNSW Sydney in partnership with Solar Aid, The State of Repair in the Off-Grid Solar Sector report urges industry investment in repair-focused approaches to boost energy access and reduce waste in hard-to-reach areas.
Over the last decade, household solar products have transformed energy access in remote regions, offering affordable electricity to millions.
However, these devices, often essential for daily needs, tend to fall into disrepair, posing a major challenge for communities relying on them.
The report estimates that over 375 million solar energy kits have been sold worldwide, primarily to populations in the Global South, illuminating more than half a billion people.
Despite this success, more than 250 million of these products are believed to have broken down prematurely.
Associate Professor Paul Munro, co-author of the report said: “If these products can be repaired, people will have better and more consistent access to light and electricity at the household level. It would reduce waste flows in countries where recycling and waste processing facilities are often limited and would enhance the sector’s sustainability and reputation.”
The study found that 90 per cent of broken products are technically repairable, but many households retain broken devices, hoping they can be fixed in the future.
Access to spare parts is a significant challenge for off-grid solar distributors, with logistical difficulties in reaching remote areas for repairs.
The report calls for manufacturers to embrace a more open approach to repairs, suggesting that distributors and third-party technicians could play a larger role in maintaining products.
Recommendations include the development of open-access repair materials to enable basic DIY repairs and the adoption of a repairability rating system to guide consumers and investors in selecting products.
Batteries were identified as the most common source of repair needs, suggesting that standardised, widely available batteries could streamline repairs.
Dr Shanil Samarakoon, report co-author, emphasised: “Where possible, the types of batteries used in off-grid solar products should be standardised, made more readily available in locales, and integrated with repair-friendly designs.”
As the industry grows, UNSW researchers plan follow-up reports to track progress in repair initiatives, with hopes to see a shift toward longer product lifespans and widespread repair practices.
Associate Professor Munro concluded: “The sector should see repair as an opportunity to fulfil its responsibilities to its customers and the planet. Longer-lasting products and warranties, along with a repair-friendly approach, should become the norm.”
