These meticulous processes in energy balancing not only lay the groundwork for a sustainable business model but also exemplify a convergence of engineering precision and technological innovation.
Low-voltage, Efficient DC Appliances
Specialized Solar Systems has dedicated years to crafting, refining, and rigorously testing low-voltage DC products, ensuring both efficiency and durability. Our business model revolves around meeting diverse energy demand profiles. We strategically combine these low-voltage DC appliances in different configurations to cater to a wide range of demands, effectively fulfilling consumers’ preferences and needs.
Energize Your World: Tailored DC Bundles for Seamless 24/7 Power
Blending various low-voltage DC appliances creates a comprehensive 24-hour load profile. This profile becomes the cornerstone for establishing kWh specifications when constructing energy generation systems. We offer attractively packaged DC energy bundles tailored for consumers, aligning seamlessly with their energy appliance requirements.
Solar-Powered Microgrid Distribution Methods
Solar generation and storage DC microgrids offer a promising solution to bridge gaps in disconnected grid infrastructure. In the design of low-voltage DC microgrid systems catering to full household power, reliability, modularity for future growth, and minimal maintenance are key considerations.
Utilizing low-voltage direct current compliant with regulatory standards ensures energy supply within a range with minimal risk of dangerous electrical shock. This characteristic facilitates swift training and the deployment of installation processes. Frequently, projects leverage unskilled local labor for system installation and maintenance, contributing to economic improvement.
Solar Tower Power Distribution
Solar towers present an advanced solution, enabling higher capacity and intelligent devices with smart networking features (ITC) for efficient energy generation and storage. To meet the consistent demand profile, energy must be distributed through wired reticulation among connected households, utilizing bundled DC appliances with varying DC voltages.
For instance, if a solar tower has a load profile of 3200W over 24 hours and all connected households use the same bundled DC appliance with a load profile of 200W each over the same period, the Solar tower can effectively supply energy to 16 houses daily. The advantage of a gridded system lies in the fact that consumers don’t all use their maximum demand profile simultaneously, allowing for better energy balancing.
Innovative Energy Management at the Core: The Technology Inside Solar Towers
Harnessing state-of-the-art industrialized technology, a solar tower houses its internal energy management hardware within a tamper-proof tower head. This serves as the hub where the system’s core intelligence consistently validates data between internal hardware configurations, autonomously making management decisions based on these configurations, all while integrating safety features.
Recorded data on energy generation, stored energy, and consumed energy, along with other relevant datasets, is efficiently transmitted to cloud-based servers with minimal data overhead. This is achieved through a variety of connectivity protocol options tailored for efficient and secure data delivery.
Standard and Management Systems
Every Solar Tower seamlessly integrates into remote management platforms, providing comprehensive system and customer management, billing services, point-of-sale administration, consumption management, switching controls, and more. Renowned for their durability, solar towers are meticulously constructed, set up, and maintained to adhere to the highest specifications and safety standards. Harnessing the latest technologies, these towers exemplify cutting-edge engineering with features such as:
Energy management applications effortlessly tap into this wealth of information, granting solar specialists the ability to remotely program and configure key components for optimal performance. The delicate balancing act of energy resources ensures a seamless match with the load demands of households’ DC appliances. Any surplus energy is intelligently directed, either distributed or stored for later use.
In a 24-hour cycle, each household’s DC appliance bundle operates at a specific wattage. The consumption is precisely monitored and reset upon completing the cycle. In cases where the total usage exceeds the load profile over a cycle, automated actions kick in. These can include notifying the consumer to reduce usage or automatically switching off the energy supply. To ensure safety and control, each household is equipped with a DC meter featuring short-circuit protection and a configurable peak usage threshold (current limiter).

PAYGO Billing method, unique:
The PAYGO billing package is a rental-based payment for daily usage upfront billing structure.
The customer only pays for the duration of the daily energy supply.
PAYGO allows for varying amounts of value-driven rates to be added to a PAYGO billing package giving a customer attractive bundled options (Days versus Amount) when making payments.
It includes ON and OFF switching directly related to a bundles’ expiry date, account balance, and 24-hour load profile consumption calculation total.
CONTRACT Billing:
The contract billing package is a rental-based monthly debiting billing package.
A value is set for the energy supplied, and this value is deducted monthly on a defined day every month.
It includes ON and OFF switching directly related to the account balance on the monthly debit date and a 24-hour load profile consumption calculation total.
The package includes a reconnection value and, if selected, will charge the account with the value if switched off due to a lack of payment.
AD-HOC DEBITS AND CREDITS:
Both billing packages support ad-hoc account debits and credits, which can be allocated to a customer’s account with detailed descriptions.
For example, if a technician is sent out to replace a broken LED DC light bulb, this can be charged directly to the customer’s account and will only be due for payment at the billing package debit or expiration date.
Alternatively, a credit value may be issued if, for example, the system had to be switched off in order to fully recharge the battery after a very bad patch of weather.
Every transaction is logged with the user-administrator details in an advanced searchable audit trail.

650 DC Solar Home Systems Project at the Collins Chabane Local Municipality
Following the success of 2000 Solar Home Systems produced and installed for the DOE by Specialized Solar Systems, another 650 were recently completed in the Collins Chabang Local Municipality district.
Collins Chabane Local Municipality is a municipality situated in the Limpopo province of South Africa. It was established after the August 2016 local elections by the merging of portions of two local municipalities namely Thulamela and Makhado.
The town, Malamulele, is the seat of the municipality. The main economic sectors are agriculture, community services, finance, trade and transport. The households are situated in rural villages and are currently assisted by 72 councilors for the region.
Solar Electrification Application Procedures
There is currently a large number of households without access to electricity. A need analysis was completed in collaboration with the Department of Energy and in conclusion, an allocation of 650 households was set aside for Specialized Solar Systems locally produced Solar Home Systems (SHS) installations. These were identified as homes without access to the National Grid which will not be serviced by the National Grid for the next three to five years.
The application which was submitted was subjected to an inspection to verify the need and to discuss the implementation plan and procedures that are required for final allocation. This included adjusting the Integrated Development plan as well as verifying the list of beneficiaries. A provision for maintenance had to be secured in the form of the funds received from the Treasury for indigent members of the community and the allocation of the Free Basic Electricity portion for maintenance.
The equitable fund for indigent residents makes provision for assistance in electrification. It is therefore important that the indigent register stays updated and the information of installations performed will also assist the local municipality in this task.
This process was completed, the inspection by the Department of Energy was performed and 650 installations was allocated to the Collins Chabane Municipality.
Scope of work
Specialized Solar Systems with Subcosol Consortium were appointed as a Department of Energy Service Provider with a three-year contractual obligation to install Solar Home Systems in South Africa, as and where required. This agreement was concluded in 2016 and phase three was completed by the 31st March 2019.
This follows on to the completion of the 1000 non-grid farm workers homes that were installed by Specialized Solar Systems in the Oudsthoorn district on behalf of the Oudtshoorn Municipality in 2017 and also the 1000 non-grid homes in the !Kheis Municipal area successfully completed in March 2018.
Project Plan
Verification of Solar Energy Recipients
Having received the appointment, a formal introduction between the Municipal leaders and the Specialized Solar Systems and Solar Visions Team members were facilitated by Serame Moeketsi representing the Department of Energy.
Verification of the process in verifying the recipients and areas to be installed was established and confirmed by the local councilors representing the wards.
Information was shared with demonstrations of the Solar Home Systems and the expected time frames for completion.
Community Meetings about Solar Energy Implementation
Community meetings were conducted in villages as needed, facilitated by local councilors and representative of Solar Vision, responsible for the ongoing maintenance program.
The separation of tasks roles and responsibilities between the consortium members (Specialized Solar Systems and Subcosol) was as follows:
The Implementation Team
The implementation Teams were constituted as follows:
Three installation teams from SUBCOSOL and one Local installation Team from the Collins Chabane Local Area. The mixing and matching of installers accommodate local logistics and ensured local skills left behind. Local installers will also assist with post-installation maintenance.
Administration Co-coordinators was deployed by Solar Vision on the project. This aspect of local job creation, as well as an understanding of the project dynamics, was used in collaboration with the local ward committee members in identifying the appointed employees. This will also assist with the maintenance plan by utilizing the administration skills of a local coordinator reporting to Solar Vision.
One Subcosol installation supervisor will do training as well as quality assurance – this is a resource with proven installations- as well as supervisory skills.
One Subcosol Project Manager will deal with planning, draughting strategic documents, performance-based budgeting, confirming implementation plans and monitor the progress of these plans.
As soon as the consignment of equipment reached the installation sites, it was allocated according to the beneficiary list in that location. The Teams then started the installation process. The administration team followed on with the Beneficiary Acknowledgement Forms where each beneficiary acknowledges that he/she has received the Solar Home System hardware and confirmed that it was successfully installed at the house with the recorded GPS coordinates of the home.
In the Beneficiary Acknowledgement Form (BAF), the beneficiary pledges to abide by the norms and standards of utilization as explained to them. In terms of this pledge, the beneficiary must report any fault or non-performance of the system to the Representative Agent for attention and repair. It is a good measure to prevent tampering and to prepare the installations for the Maintenance Programme.

Beneficiary List
More applications were received than what was allocated and provided for and names were collected and referred to the Municipality for further application to the DOE.
Manufacture and Supply
Specialized Solar Systems is not only manufacturing and supplying Solar Home Systems to fulfill their contractual obligation with the DOE but also supply other Service Providers as was done in the past.
During this round of installations, it was decided to also supply Solar Vision in Polokwane with Solar Home Systems to be installed in the Tubatse Municipal Area, Limpopo. A production schedule for the manufacture of the Solar Home Systems was planned and the procurement process for system components and consumables was executed.
Maintenance
Solar Vision is the appointed Concessionaire responsible for all maintenance in the Limpopo Province. An information meeting was conducted at the Solar Vision Offices in Polokwane attended by senior management, technical managers and all the team leaders responsible for installations and maintenance. Mateli Mapuntsa from Subcosol, responsible for the operations during the installations period, was also present and communication channels for future collaboration were established.
A maintenance agreement between the Municipality and Solar Vision is in place which facilitates the collection of FBE funds to perform the ongoing maintenance.
Specialized Solar Systems will facilitate the further training of the maintenance team as and when required as well as the availability of replacement parts and additional equipment and appliances to be installed on the beneficiaries’ request.
Flow batteries are a well understood class of energy storage technology. To date, production flow batteries have been relatively large in terms of both physical size and storage capacity. Redflow has successfully designed and commercialised a small, modular, flow battery based on zinc-bromine reactants — referred to as a ZBM2 (Zinc-Bromine Module).
Redflow Limited has received an order to supply five zinc-bromine flow batteries for a pilot project to provide standby energy storage for mobile phone towers in South Africa.
