Algiz 7 helps bring electricity to healthcare facilities in developing countries

A Rwandan solar energy company uses the Algiz 7 rugged tablet for remote data collection for healthcare.


Supply consistent, clean power to rural healthcare facilities in the developing world.


Using the Algiz 7, collect detailed energy data to inform development of a self-contained solar energy generation system.


The ability to design and build energy systems that will save lives and improve healthcare outcomes.

Thanks to the powerful rugged mobile technology of the Handheld Algiz 7 rugged tablet computer, rural healthcare clinics in Rwanda are helping create a model for efficient, dependable energy production that will save lives.

Healthcare is essential to human survival. Access to trained practitioners, clean facilities, and vital medications and supplies makes the difference between life and death, especially in the developing world. But effective modern healthcare requires electricity. Without reliable power, the best doctors and clinics can be left helpless.


Tremendous strides have been made in providing access to healthcare in the developing world – and yet 75 percent of the world’s population relies on healthcare from facilities that suffer from an insufficient or intermittent energy supply. A lack of electricity is central to this risk – often there is medical equipment available, but no power to run it. A solar power system may even be installed but not operating.

This dilemma is what Great Lakes Energy (GLE) is aiming to solve. Their CEO, Sam Dargan, describes GLE as “a solar innovation company.” For the past decade, GLE has been immersed in the energy challenges of rural healthcare, focusing on photovoltaic (PV) solar systems as a solution to power needs.

GLE is developing a self-contained solar energy generation system called SESH (Solar Energy Services for Healthcare) that can supply constant and clean power to healthcare facilities. The system can be monitored in real time, allowing operators to prevent failures before they occur. SESH also monitors a variety of healthcare functions, from refrigerator temperatures for vaccine storage to usage patterns of lights and medical equipment.Algiz 7 helps to develop reliable electricity sources for healthcare facilities

The challenges in implementing SESH systems are daunting. The facilities GLE works with are typically rural and off the power grid. And healthcare clinics have continual but highly unpredictable energy demands, with spiking needs at irregular intervals. So two years ago, Dargan and GLE “embarked on a journey to find a way to make PV a much more sustainable electrification resource.”

But testing, adjusting and perfecting a system like SESH requires data – lots of data. In remote areas, under rugged conditions. And all they had was standard laptop computers.

“The roads here are very rough,” Dargan says. “Carrying company laptops into the field resulted in a high failure rate for our computers.”


This was a perfect opportunity for Handheld’s powerful Algiz 7 tablet. The rugged Algiz 7 features an Intel Atom processor, along with massive 128 GB storage capacity and 4 GB of DDR3 RAM. It also meets stringent MIL-STD-810G U.S. military standards for withstanding humidity, vibration, drops and extreme temperatures, and meets IP65 standards for sealing out dust and water. And despite its brawn, this rugged tablet computer is compact and portable, weighing only 1.1 kg (2.4 pounds).

“This is the kind of technology that unlocks possibilities for a worthwhile project like Great Lakes Energy’s work in Rwanda,” says Carsten Billeschou, Managing Director for Handheld Europe. “A remote project like this is only successful if its equipment holds up, and the Algiz 7 is a perfect tool for a noble goal. We were glad to help.”


So GLE put its Algiz 7 rugged tablet computer to work. Its lead role is to collect the critical data that informs the design and refinement of the SESH system. The project approach is to blanket Rwanda’s rural healthcare system with sensors that measure energy performance and status, and measure how each clinic’s staff uses electricity.

Data loggers, which collect specific information on energy use – timing, type, load levels – are installed in numerous health centers across Rwanda. “We leave each logger in place for two weeks, after which we collect the data. The Algiz 7 is perfect for this,” Dargan says.

With data from multiple points in the field, GLE uses specialized software loaded right onto the rugged tablet to analyze the data and manipulate the inverters their PV systems use to control energy flow.Algiz 7 collect detailed energy data to inform development of the energy generation system

Not only that, but the software generates SMS (text) messages directly to each clinic’s staff, advising them how to consume energy in ways that won’t crash or overdraw their solar energy system.

“A lab technician receives a notice that, due to excess energy production, right now is a good time to run the autoclave,” Dargan says. “And the nurse receives a notice that she’s left the lights on in the middle of the day.”

The system can also apply the energy-use data to make regular maintenance services more predictable going forward, and to quantify the impact of a reliable energy source.


The Algiz has been instrumental in bringing all the aspects of the project together. First and foremost, it’s a perfect tool for remote sites. “The compact form, rugged build and serial ports have made this rugged tablet computer extremely useful for our work in the field,” says Ivan Asiimwe, an electrical engineer for GLE.

And the future of rural healthcare is brighter because of GLE’s work.

Dargan takes a moment to neatly sum up the big picture: “The technology enables the data. The data enables the services. The services increase the value of the energy system to healthcare providers and officials. The reliable supply of electricity saves lives.”
