Solar Hybrid Technology

Reliable power for the 21st century

Solar Hybrid Technology.

System components:

  1. Solar panels can be installed on the roof or on the ground. They convert the abundant solar power into usable electrical power. Their performance is guaranteed for over 25 years
  2. Solar inverter: converts the direct current (DC) produced by the panels into alternative current (AC) to suit your appliances
  3. Enerwhere Hybrid manager: optimizes power supply from solar, utility grid and back up generators at any point in time and communicates real time data to enerwhere online monitoring platform

Solar-Diesel Hybrid Systems

Enerwhere’s core offering are cost-effective, reliable and practical solar PV-diesel hybrid systems. We build these systems by synchronizing our modular, transportable solar generator units with conventional ultra-high efficiency diesel generators. In a typical configuration the solar system covers up to 95% of the daytime demand, while the diesel generators guarantee reliable power 24/7, even when the sun isn’t shining.

Enerwhere’s proprietary hybrid controller enables the smooth interaction of all components of the system by continuously monitoring load, solar production, the residual load on the generators, and spinning reserve requirements. If any parameter changes (e.g. if solar production drops due to a passing cloud), the system reacts in milliseconds to adjust generator output to the new requirement. More advanced versions of the controller can take into account solar radiation forecasts from sky cameras or trigger demand management to provide even higher reliability levels.

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

Solar-Battery 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.

Another good application for solar-battery systems is peak shaving of industrial loads (e.g. tower cranes on construction sites, concrete batching plants or large mill motors in mining), thereby helping to increase power quality and reduce strain on the diesel generators. Batteries can also serve as buffer for hybrid grids with very high (>80%) solar penetration, allowing to switch of the generators during the day.

Enerwhere uses state-of-the-art Lithium 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 high-power inverters to provide full backup and black start capability.

Real-time monitoring

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 monitored remotely from Enerwhere’s control center in Dubai, allowing our team to continually assess and monitor the efficiency of our plants under real-life conditions in the field, no matter how remote the site. In case any problems are spotted by our control center, a service team is sent to the plant to correct the issue before they lead to operational problems for our clients.

We have installed hundreds of sensors measuring everything from ambient temperature to fuel flow, power quality and solar radiation on our fleet of mini-grids around the Middle East. We are continually expanding our sensor network, thereby growing a unique dataset about the real-life energy consumption profiles of camps, construction site offices, hotels and more.

This “Big Data” approach allows us to continually improve our performance over time, preventing outages and lowering costs in the process. It also enables us to offer our clients advice on how to improve the energy efficiency of their facilities, thereby further lowering power costs and emissions.
