SOLAR POWER SOLUTIONS

Solar is the most abundant, best developed and reliable renewable energy available at the moment. The technology has been tested and proven. The feasibilities have been shown.

SEG has built up the proficiency, supplier relationships and on the ground capacity to deliver solutions.

Background - Residential Solar Power Solutions

SEG provides residential solar from starter system that just run the basics to full off-grid systems that can run a whole house.

The systems types we do include: Grid-tied (self-consumption and net-metering), off-grid and grid-interactive hybrid systems.

These are mostly meant for home owners either in cities (grid-interactive) or on farms/small holdings (off-grid/grid-interactive).

Residential conversion to solar is a relatively easy one if energy efficient appliances, geysers and stoves are used in combination with the solar solution. A mind shift is required as the customer ends up owning and managing their own power plant at home.

A comprehensive energy audit and site assessment is done beforehand to ensure that a client will have a right sized, sustainable solution with a long system life expectancy.

Systems pay themselves off in energy production and energy savings. The average pay-off period is 6 to 10 years compared to a 25 year life of system. These systems starts paying for themselves from day 1.

SEG does turnkey installations that includes: sizing, design, feasibilities, engineering, component supply, electrical reticulation, installations, commissioning, securing, monitoring, maintenance & management. 

Background - Commercial Solar Power Solutions

Commercial solar systems are solar systems used in Corporate & Industrial (C&I) markets on office blocks, shopping centers, factories, mines, commercial farms, hotels, lodges, Security Estates, etc.

The most widely used systems are grid-tied, self-consumption systems due to the energy production curve of the solar plant being comparable to the day usage curve in the average building.

Hybrid systems using a combination of solar, batteries, gen-sets and/or wind turbines are also available. Hybrid systems allow for off-grid micro-grids to be built in remote locations like mining compounds, military bases and isolated communities where grid access is difficult or expensive.

Community solar systems are large scale systems that service whole communities like golf estates, security estates, retirement villages, etc. These can either be installed as one system or dispersed on roof, carports or ground mount installations. The dispersed system works like one big power plant.

Commercial solar systems can be installed on rooftops (single or dispersed), carport, parking garages or ground-mount locations.

A full energy audit and feasibility analysis is conducted by our engineers before the system is installed to optimized the design and minimize installation costs. The grid/ gen-set provides any additional power requirements.

SEG does turnkey installations that includes: design, sizing, engineering, financing arrangements, component supply, electrical reticulation, installations, commissioning, management & Maintenance.

We are a full wrap EPC (Engineering, Procurement & Construction) company. As well as an IPP (Independent Power Producer). 

Background - Utility Scale Solar Power Solutions

Large scale (Megawatt size) solar farms that interconnect with local, micro, municipal &/or the national grids. Such farms can supply power either to one large scale user like factories, industries or mines or multiple small scale users like municipal customers, communities, security estates, office blocks/parks or office parks.

This power can either be used for:

  • Self-consumption: Used on the site where it is produced.
  • Wheeling onto the local grid: Power is injected onto the local municipal grid for example where it is distributed to users on that particular grid. Excess power can be wheeled onto the national grid.
  • Wheeling onto the national grid: This power is either sold to Eskom or other power consumers using the national grid to distribute the power.
  • Banked: Power is generated and wheeled on the grid where it is used by other users. The banked units/credits can then be used at a stage when the solar farm is not producing power.
  • Stored: Grid-scale storage solutions like lithium batteries can be implemented to allow for smoothing out of the delivery curve, transition to backup gen-sets, power storage or peak shaving to reduce maximum demand charges.

We act as project developers, EPC Company (Engineering, Procurement & Construction), IPP (Independent Power Producer), Project Financing originators & General Consultants.

SEG in partnership with Solar Man, Astraea Energy and SunPower Corporation is working on 6 projects throughout South Africa ranging from 1 to 50 MW in size. The farms will connect to local municipal grids and be a second energy supply source. Solar power will be a primary supply with Eskom supplying whatever additional power is required. Implementation will be from the beginning of 2018.

Introduction to Solar Power Solutions

Solar power systems use the energy generated by the sun and converts it into energy that can be used in homes, businesses, commerce or industry.

This energy can either be:

More info
 

Off-Grid Solar Systems

  • With these systems you don't need a grid connection
  • The whole system is self sustaining, the PV panels charge up the battery bank that stores the energy
  • The components will include: Solar PV Panels, MPPT Charge Controllers, Batteries and an Inverter(s)
  • Backup would be a larger battery bank, grid connection or gen set
  • This is ideal for off-grid homes, lodges, farms, holiday homes and locations where a grid connection would be expensive/unsightly to install

 

Grid-Tied Solar Systems

  • A grid-tied system interphases with the grid
  • Power can either be pushed back into the grid (net metering/Small Scale Embedded Generation) or in the case of a self consumption system, the day loads are fed by solar power
  • No batteries required, so inverters switch off when the grid goes off
  • The components will include: Solar PV Panels and an Inverter(s)
  • The grid-tied systems are best for reducing your energy bills in the most cost effective way

 

Grid-interactive (Hydbrid) Solar Systems

  • A grid-interactive solar system is a combination of an off-grid and a grid-tied solar system
  • A hybrid system can either be set to store power in batteries, service loads or push power back into the grid
  • A backup battery reserve will be available to run loads in case of power outages (even multi-day ones)
  • The components will include: Solar PV Panels, MPPT Charge Controllers, Batteries and an Hybrid Inverter(s)
  • These systems work well in town or on farms or anywhere where sustained power availability is important

 

Residential Solar Power

  • These are solar power systems installed at private houses both in towns and on farms
  • Off-grid, grid-tie or grid-interactive systems can be installed
  • Usually roof mounted solar panels with battery bank(s) and inverters installed in a garage or battery room

 

Commercial Solar Power

  • Commercial solar systems are installed at busineses, office blocks, shopping centres, large farms, etc
  • In general grid-tied solar systems are installed in these locations to minimise energy bills
  • A small battery bank can be installed to accomodate power outages or generator startup requirements. 

 

Utility Scale (1MW+) Solar Farms

  • Utility scale solar systems push power back onto the local grid, municipal grid or National grid (Eskom grid)
  • The generated power is first used on the local grid, the rest of the power is wheeled to other users on the national grid.
