Water, Energy & Infrastructure
Solar & Electrification
Reliable power for children, schools, water systems and community services in places the grid does not reach.
- 2,224 Junior and 24 Student lights in 2025
- 24 schools reached in the planned distribution
- Solar systems designed for remote maintenance
When the sun sets, essential work should not stop
In an off-grid village, darkness affects study, safety, communication, water and the ability to prepare for tomorrow. Solar & Electrification turns available sunlight into practical hours that children, teachers and communities can use.
The programme
Energy designed around what people need to do
Electricity matters when it keeps a child reading, a teacher preparing, a water pump moving or a remote team connected. The technology is only useful if it serves that daily purpose reliably.
Our report from Mahu shows a small solar panel powering one lamp beyond the grid, and why dependable electricity matters in daily life.
Solar & Electrification works at several scales. Personal SolarBuddy lights give children safer light for reading and movement after dark. Larger photovoltaic systems support schools, water infrastructure, internet access, printing, charging and the buildings where essential services operate.
Each project begins with the use, not the equipment. Load, autonomy, location, security, maintenance and local responsibility are considered before installation. Teams return to inspect what was built, listen to users and correct problems because equipment placed far from technicians must remain understandable and repairable.

The Mbajik system was inspected nearly a year after installation, with users consulted and equipment checked.
From need to maintained power
How a remote energy system is built to last
The installation day is one moment in a longer responsibility. A useful system must be sized correctly, installed safely, understood locally and inspected after people begin using it.
Identify the use
The team records who needs power, for which activities, at what hours and what currently stops them.
Measure and design
Loads, solar exposure, battery autonomy, wiring routes, structure, security and future maintenance shape the system.
Transport and install
Panels, batteries, inverters, protection and tools travel across difficult routes before careful testing on site.
Teach responsibility
Users learn charging, safe operation, panel cleaning, fault reporting and the limits of available power.
Return and inspect
Connections, supports, batteries, inverters and actual use are reviewed so problems are found before service fails.
Reliability is part of the intervention
Power must remain safe after the team leaves
Off-grid equipment cannot depend on frequent specialist visits. Clear design, protected components, realistic loads and local knowledge are essential to continuity.
What a durable system includes
- Load assessment based on real daily use rather than equipment alone
- Correctly sized panels, inverter, battery storage and electrical protection
- Safe wiring, secure mounting and components protected from weather and misuse
- Simple operating guidance understood by teachers, families or local supervisors
- Routine cleaning, visual checks and a clear way to report faults
- Documented follow-up that compares technical performance with user experience
What puts continuity at risk
- Adding loads that exceed the system’s designed capacity
- Damaged cables, loose connections, water entry or unsafe alterations
- Batteries left without monitoring or used outside safe operating limits
- Panels shaded, dirty, unsecured or installed without access for inspection
- No person locally responsible for basic checks and fault reporting
- Equipment donated without training, spare planning or a return visit
At SDN Mbajik, power now supports classrooms, teachers living on site, internet, printing and evening study. Returning after installation is part of the work.
Energy in daily life
Electricity connects services that used to stop at dusk
At SDN Mbajik in Haray, six teachers sleep on site because the school is hours from town. The solar system serves 55 pupils and supports lesson preparation, computer use, printing, internet access and lighting after sunset. Its value appears in ordinary tasks that can now continue.
Study and teaching
Children can read after dark while teachers prepare and print lessons without travelling to town.
Water systems
Solar pumping can move water where gravity or a public electricity connection is unavailable.
Communication
Charging and internet access connect remote schools and teams to information, coordination and support.
Safer evenings
Personal lights reduce dependence on darkness and polluting flame-based lighting for study and movement.
What changes in practice
Reliable energy returns usable time to a community
Children can keep learning
Reading and homework no longer have to end simply because daylight has disappeared.
Teachers can work on site
Preparation, printing, charging and online resources become possible at the school where they live.
Water and communication become more resilient
Correctly designed solar power can support pumps, connectivity and field equipment beyond grid reach.
Responsibility continues after installation
Training and return inspections make users part of keeping the system safe and useful.

Three Crosses Near Haray, and a Prayer for What Comes Next
Three wooden crosses stood on a hillside near Haray during our journey to evaluate a school solar installation in East Sumba. Alex stopped to pray for the future of Fair Future Foundation, the Rumah Kambera Community Socio-Medical Centre, and the people the teams still need to reach.
A Small Solar Panel and One Lamp in an Off-Grid Village in Mahu
A small solar panel rests on a chair beside a road in Mahu, East Sumba. Out of view, an old scooter battery stores enough power for one 12-volt lamp in a home. This photograph shows how families make light where there is no grid, and why village and school electrification must be dependable.
Solar Power at SDN Mbajik | Nearly One Year On
Nearly a year after installing solar power at SDN Mbajik, we return to Haray, East Sumba, to inspect the system and listen to its users. For 55 pupils and their teachers, electricity now means evening study, printed lessons and access to online resources.
SolarBuddy Education East Sumba – Solar Light
In many schools without electricity, SolarBuddy education East Sumba becomes more than lamp distribution. It brings structured guidance, hygiene awareness and printed learning material to children who rarely receive personal documents. Light becomes a medical and educational tool.
School Health Posters – Education in Action
In rural Indonesia, school health posters are more than visual aids. They are daily prevention tools. At SDN Bidiwai, teachers received SolarBuddy lamps and a full set of educational materials that transform classrooms into spaces of long-term community awareness.
SolarBuddy distribution update reaches final phase
The original plan counted 24 schools. Field reality allowed more. Careful logistics and constant presence made it possible to extend distribution beyond expectations, proving that long term engagement creates room for added impact where children need it most.
Solar Light for Children in Ultra-Rural Regions
This new picture of the day shows solar light for children delivered through patience and care. In an ultra-rural classroom, a lamp is not simply handed over. Time is taken to explain, to show, to ensure understanding. For children living without electricity, light means safety, learning, and dignity once the sun goes down.
SolarBuddy distribution reports now available East Sumba
The two documents prove that light delivery is more than numbers. They show routes taken, funds used, and hours of study gained. They record teacher involvement, safer evenings, and lower injury risk. Evidence builds trust, and trust keeps the lights arriving where they are needed most.
SolarBuddy lamps Matawai Katingga protect child health
In Lapinu, an isolated village in Matawai Katingga, SolarBuddy lamps Lapinu children change daily life. Without electricity or clean water, evenings meant smoke, kerosene and darkness. Our joint teams from Fair Future and Kawan Baik bring light as a medical tool, to protect lungs, eyes and learning
SolarBuddy lamps East Sumba – quality control to classrooms
At Rumah Kambera we checked 2,224 SolarBuddy lamps East Sumba one by one. Volunteers, Rotary, Fair Future and Kawan Baik tested brightness, panels, switches and batteries, fixed faults, logged QR codes, and packed each unit for long journeys to schools with no electricity. Light prevents injuries, improves study, and protects health.
SolarBuddy quality control for Sumba’s children
Over two focused days at Rumah Kambera, volunteers and Rotary members tested, repaired, labeled, and registered 2,224 SolarBuddy lamps so children and schools in East Sumba can study safely without toxic kerosene and darkness.
SolarBuddy lamps arrive in Rumah Kambera
The 2,224 SolarBuddy lamps have arrived at our base in Rumakambera after six months of challenges. These lamps will transform lives, offering safe lighting, improving education, and aiding medical care in villages without electricity.
Accountability
Installed equipment creates a continuing responsibility
We document specifications, costs, locations, recipients, training, inspections and faults. Energy projects are judged by safe performance and daily usefulness over time, not by the moment equipment is handed over or switched on.
