     Hybrid

     See details below

We advise on energy usage & energy cost saving opportunities. Our main objective is to enable you to reduce your energy bill and to save on energy cost.

Grid Tied

 

  • Grid-tied solar power systems are connected to the local municipal electrical grid and will allow you to generate solar power for your residence and route excess power into the local municipal electrical grid.
  • A grid tied system will allow you to use solar power as well as electricity from the grid, as grid-tied systems do not need to produce 100% of the electricity demand for your residence.
  • When there is no demand for electricity, the solar system will send excess power back into the grid for use elsewhere.
  • When a residence is using electricity, but the solar panels aren’t producing enough electricity for instance at night, or on a rainy day, electricity from the grid supplements electricity from the panels.
  • Grid-tied systems are the most simplistic type of solar power system and do not require any batteries. Thus, you will not be able to store any power.
  • Grid tied systems are mainly considered for its cost savings potential.
  • Owners of a grid-tied systems normally complete a net metering agreement with their local energy provider. This agreement allows energy customers to receive credit for the excess energy they generate. Net metering policies and agreements are different for each local energy provider and you will have to obtain information from them.
  • Living with a grid-tied solar system is no different than living with your local municipal electricity provider, except that some or all of the electricity you use comes from the sun.
  • Grid-tied systems do not provide protection against Eskom power outages. When the electrical grid fails, grid-tied systems will not continue to operate. This is a regulating governance that allows the energy provider to fix the power lines safely without wasting time identifying solar energy systems that are still feeding electricity into the power lines.
  • Life expectancy of a quality grid tied system is 25-30 years and it will require almost no maintenance.

Grid tied system components include:

  • Grid inverter
  • Solar panels
  • Roof mounting rails & brackets for your roof type, electrical connectors (breakers, fuses & wiring) and earth cable for safe connect to the grid.
  • A monitoring system to monitor energy production for record keeping & optimisation purposes is available as an optional.

 

 

 

 

 

Off-grid (Island)

 

  • Off-grid systems (also referred to as Island systems) are used where no electricity is available to ensure the supply of power without a grid connection.
  • Off-grid systems operate independently from the local municipal energy grid to provide solar power/electricity to a residence. An off-grid needs to produce enough solar power to cover 100% of the required energy needs of the residence.
  • Most residences have an electricity demand in the evening or at night, thus the reason for off-grid systems will require a battery bank or Super Capacitor for storage and usage at a later stage when required.
  • Off-grid systems are more complex and less flexible than grid-tied systems.
  • Off-grid systems are the most expensive solar power solution as it requires a number of batteries for storage purposes.
  • Off-grid systems are more common in remote locations without an energy service.
  • An off-grid solar system must be large enough to produce enough solar power to cover 100% of the energy needs.
  • In all off-grid scenarios, electrical usage must be monitored and kept below the maximum output of the panels and batteries, as there is no grid-source to supply the excess demand.
  • The life expectancy of an off-grid system will depend mainly on the quality of the battery bank and or storage unit, the quality of the inverter whilst most quality panels will last 25 to 30 years . All batteries have a number of cycles and will last according to the cycles and usage patterns. Quality batteries can last between 10 – 15 years, Sirius Super Capacitors are new technology that offers 1,0 million cycles and a live expectancy of 45-years plus and it is therefor obvious that this new technology will have a mayor impact on future storage of energy.
  • Off-grid systems will require minimal maintenance, however, the batteries may require annual check-up and top-ups in most cases, depending on the type of battery installed.

Off-grid system components:

  • Off-grid inverter
  • Solar panels
  • Battery bank or Sirius Super Capacitor
  • Charge controller (to protect the battery bank from overcharging)
  • Roof mounting rails & brackets for your roof type, electrical wiring & connectors, earth & connection fittings for safe connect to the grid and operation.
  • Monitoring system to monitor energy production for record keeping & optimisation purposes available as an optional.

 

 

Back-up
  • The main purpose of a back-up system is to avoid power outage or load shedding and to allow you to enjoy an independent, reliable 24-hour energy supply.
  • A back-up system supplies power when Eskom power is unavailable.
  • Back-systems are normally designed to cater only for the supply of power to essential equipment only.
  • When Eskom power is available the unit acts as a charger ensuring the charging of the battery bank.
  • During a power outage the inverter converts the stored battery power to normal AC power.
  • In cases of extended power failures the back-up system can be further charged with a generator.
  • Back-up systems can be installed with or without solar panels. A back-up system with solar panels is similar to an off-grid system, except that it is smaller in size and production capacity.
  • We recommend back-up systems that are solar ready and that can be integrated into a complete island or hybrid system to ensure maximum future value for money.
  • Life expectancy of back-up systems will depend mainly on the quality of the inverter and the batteries or capacitor that you install. Over utilization of back-systems will shorten its life expectancy, this does not apply when a Super Capacitor is used.
Back-up system components:
  • Off-grid inverter
  • A small battery bank or a Super Capacitor
  • Charge controller (to protect the battery bank from overcharging)
  • Electrical wiring & connectors for safe connect to the grid or mains.
  • Solar panels are optional

 

 

 

 

 

 

 

Hybrid and ESS function
  • Hybrid systems are a clever solution that incorporates a grid tied system, an off-grid system and a backup system into a single system solution.
  • Certain off-grid inverters with ESS (energy storage system) design functionality can also operate as a hybrid solution. Inverter with the ESS function are installed as a grid tie with battery storage. This will offer best of both worlds, grid tie and off grid in one solution. Excess solar power generated can be stored in the batteries and if more power is required than what the solar system is delivering it can use power Eskom power to cater for the excess. 
  • Hybrid systems are used for self-consumption with a grid presence to offer you all the benefits of the grid, off-grid and backup systems.
  • Normally grid-tied systems can be upgraded to include a battery backup. An Off-grid or Hybrid inverter and a battery bank of deep-cycle long life batteries or Super Capacitor are then added to upgrade the system to a complete Hybrid solution.
  • With Hybrid systems the backup batteries or Super Capacitor are charged by either or both the grid and the solar panels.
  • The system will run a residence off-grid during the night, discharging the batteries to a predetermined level. Unlike Grid tied systems the Hybrid system freely switches to off-grid operation in cases of grid power failure, which means that your green power will be available even during power outages.
  • Hybrid systems are cheaper than Off-grid systems as it usually requires a smaller battery bank or storage unit to supply only essential equipment during power outages.

Hybrid system components:

  • Grid & Off-grid inverter (or only an Off-Grid inverter with ESS function)
  • Solar panels
  • Battery bank or Super Capacitor
  • Charge controller (to protect the battery bank from overcharging)
  • Roof mounting rails & brackets for your roof type
  • Electrical wiring & connect fittings for safe connect to the grid and operation.
  • Monitoring system to monitor energy production for record keeping & optimisation purposes.
