Reliable power for the 21st century

Hybrid Systems

Our core offerings are reliable and cost-effective solar-diesel hybrid systems, also known as mini-grids.

These mini-grids are made of modular, transportable solar generators and conventional high efficiency diesel generators. In sunny places like the Middle East, the solar system can cover up to 95% of the daytime demand, while the diesel generators guarantee reliable power around the clock, even when the sun isn’t shining.

Enerwhere’s proprietary hybrid controller enables the smooth interaction of all components of the mini-grid by continuously monitoring load, solar output, the residual load on the generators, and spinning reserve requirements. If any parameter changes, the system reacts in milliseconds to adjust generator output to the new requirement.

At low diesel prices, this combination is the most cost-effective configuration for systems with loads greater than 100 kW and relatively smooth load profiles (e.g. camps, construction site offices, islands, etc.).

Hybrid Systems

Solar-battery systems are often the best choice for small systems (<100 kW load), as the efficiency of diesel generators drops rapidly below 250 kVA, as well as systems with highly variable loads (e.g. tower cranes on construction sites or large motors in mines & quarries). The batteries can not only store solar energy for the night but also provide instant power bursts, thereby increasing power quality and reducing strain on the diesel generators.

Batteries can also serve as buffer for hybrid grids with very high (>80%) solar penetration, allowing to switch off the generators during the day.

We use  state-of-the-art lithium-ion batteries packaged in outdoor-rated IP65 enclosures to withstand the harshest climate conditions in the Middle East and Africa. We combine these batteries with highly-efficient, grid-forming inverters to provide UPS and black start capability.


Enerwhere includes a full remote monitoring & management suite in all of its solar-diesel and solar-battery hybrid plants as standard equipment.

All system parameters are automatically monitored remotely, with additional manual support from our control center in Dubai, where our team continually monitors the efficiency of our plants under real-life conditions in the field, no matter how remote the site. If an issue can’t be resolved remotely (e.g. due to failure of a piece of equipment on site), a service team is sent to the plant immediately to correct the issue before this leads to operational problems for our clients.

We have installed hundreds of sensors measuring everything from solar radiation to fuel flow, as well as dozens or parameters related to power quality and reliability on our fleet of mini-grids. This “Big Data” approach allows us to continually improve our performance, preventing outages and lowering both our and our clients’ operating costs in the process. It also enables us to offer our clients advice on how to improve the energy efficiency, thereby further lowering energy costs and CO2 emissions.


Soiling losses, created by sand and dust covering solar panels, are one of the major sources of production loss for solar installations in the Middle East. Without cleaning the production of a typical solar plant drops by an average of 0.7% per day, even though values can be much higher of lower, depending on the weather (a dust storm can lead to production losses of over 10% in a single day, while a good downpour will clean the panels and restore production to nearly 100%). Since rain is scarce in our region for most of the year, regular cleaning is required, with most solar plant owners opting for manual cleaning about twice a month, leading to annual average soiling losses of about 3%.

Reducing losses (and labor costs) further requires more innovative approaches, and Enerwhere is the first solar plant operators in the Middle East to roll-out robotic cleaning for commercial and industrial sites across its fleet.

The installation of these robotic cleaning systems reduces the need for manual labour and minimises water consumption, thereby lowering overall maintenance costs while enabling higher solar yields. With state-of-the art control and remote monitoring, Enerwhere is able to fully automate O&M for solar plants and deliver significantly better performance.
