Freedom Energy has a unique development platform. We have streamlined our process by utilizing the best, most flexible and easy to deploy technology available on the market and by leveraging our experience in the development and financing of renewable energy projects. The result is a uniquely efficient process which removes unnecessary design and installation costs, and allows us to offer the most competitive, quick and consistent overall solution.
We specialize in the development of hybrid systems but in some cases, depending on the project, location, and counterparty, we can offer an “Energy-as-a-Service" model where we fully finance the project's CAPEX. This approach provides a hassle-free, no-capital-required way to receive clean power and to start realizing savings immediately.
In this phase of the development process, you provide us with some basic information about your energy needs. This will typically include information regarding current energy demand, current expenses, location, prices for energy, information regarding typical operating hours, etc. The more detailed the information, the more value will be delivered by our solution.
Based on the provided information, we assess the system characteristics and devise a bespoke solution to match your specific needs as best as possible. We will assess your local conditions and match them to your needs. We will propose the best-value solution for your setup which will almost certainly bring you significant savings. The result is an indicative report for your situation. It will illustrate how the system works, its main characteristics and advantages, and most importantly - its financial benefits to you. This report will also contain an indicative offer for installing the system, conditional upon confirming the information provided.
This step in the process is optional and depends on two factors – your preference and your situation. There are two options you can opt for – purchasing the assets or establishing an ESCO-type contract. If you opt for the predefined benefits ESCO contract, we will investigate if we can offer you are eligible for this type of service. Once this is complete, we will take care of the rest.
If interest is expressed from your side following our initial report, we will continue with signing a formal intention contract and begin an investigation into the specifics of your situation. We will conduct a more detailed analysis to make sure we have the correct information in the previous step. Next, we will start organizing the development process at your premises. This will include the specific provisions for transportation, licenses, and any other costs that affect the project.
We offer a wide range of services for the management and maintenance of installed energy systems. We can remotely monitor your system and change its behavior when required. We offer system maintenance as an addition and also provide warranty on all parts, which can be easily changed by you as well. The combined effect leads to a great user experience and seamless operations.
No grid access for a new production facility
The investors faced a problem with the electricity supply of a new industrial building – the chosen location was ideal, however, the closest electricity substation was 12 km away. There were two feasible alternatives: A) a significant investment in building a new substation or B) going off-grid by installing a solar hybrid energy system and producing the required energy locally.
After assessing the plant's energy demand, a PV-based solution was designed with a back-up diesel genset for days of prolonged cloud cover. The system’s smart control makes dynamic decisions regarding power sources – when solar power is unavailable, the system draws energy from the battery storage. In case the storage unit is depleted, the diesel generator automatically starts at maximum efficiency to both charge the battery, and power the system.
Exeron MX system :: 16 x 2 kWp MPPT charge controllers SML2000 :: PV system 32 kWp polycrystalline :: 4 x 2 kW rectifiers ML2000 for inverter feeding and battery charging from DG :: 36 kVA output power, 3-phase :: Battery 48V/1560Ah :: Diesel genset 16 kVA
Power supply has been reliable since installation. The diesel genset provides additional power in winter months when there are more than 2 consecutive days without sunshine. The solar + storage component provides 90% of the required energy, thus greatly reducing OPEX and bringing significant value compared to its grid alternative.
No reliable grid access for a college building
The investor aimed tо take a 25-room college building off the grid while supplying it with electricity from 100% renewable sources. Rooms are equipped with lights, computers, air conditioners, and other electrical appliances. The building’s consumption curve is skewed towards the daylight hours with some spikes in the evenings.
The two main sources of energy are batteries and PV panels. An Exeron hybrid control system takes care of the load, battery charging and system monitoring. The system’s smart control makes dynamic decisions regarding power sources – when solar power is unavailable, the system draws energy from the battery storage: during the day the generated power from the PV modules is used for powering the building and charging the batteries. After sunset or in days without sufficient solar irradiation the load is powered by the energy stored in the battery.
Exeron CM system :: 25 x 2 kWp MPPT charge controllers SML2000 :: PV system 50 kWp polycrystalline :: 60 kVA output power, 3-phase :: Battery 4 x 48V/1560Ah, total battery storage capacity 48V/6240Ah (~300 kWh)
Power supply has been stable irrespective of climate conditions or changing seasons. The system is able to cover the energy demand without any supply irregularities.
No grid access for a telecom tower
Undisclosed, Rural Area
A network operator aimed to cover a wide area with an ultra-fast LTE data network. Our client required OPEX optimisation and low-cost maintenance solutions. The region's high ambient temperature and relative humidity (between 95% and 98%) posed a challenge the technical design team.
An IP55 outdoor cabinet with double walls and special anti-corrosive coating in combination with high temperature, multicycle batteries, developed for PV applications were installed. Forced ventilation guaranteed max Δt ≤ 7°C. A 4 kWp PV system with polycrystalline modules was chosen as the main energy source. The configuration was designed to guarantee a 48h power autonomy thanks to the correct scaling of the PV system. A small 6 kVA diesel GenSet was installed on site. It is automatically controlled by Exeron's Main Control Unit. In case there is not enough sunshine in two following days and the battery is fully used the diesel GenSet would provide back-up to power the equipment and, at the same time, charge the batteries.

OPEX costs are nearly zero. No supply irregularities have been reported to date.
