GRID TIE SYSTEM BEST FOR COMMERCIAL AND INDUSTRIAL

Grid tied systems consist of only 2 key components – solar panels and a dedicated grid tied inverter. All the electric power generated by the solar panels feeds through a main synchronized inverter directly into your distribution board and offsets the power you would normally consume from the utility.

This is the system we encourage for C&I customers mainly. This is so because your working hours are also our solar peak production hours 0800hrs to 1600hrs, you knock off when the solar production plummets on the bell like graph, During the day you are practically off the grid when the sun goes down the system will switch to the utility of which this period your usage have dropped quite significantly. For establishments without NIGHT SHIFT, your utility bill will drop by up-to 70%

Benefits of Grid-Connected Solar Systems

  • Very affordable
  • Reduces your bill up-to 70%
  • Increases the value of your property
  • Low capex cost because battery storage
  • Exceptionally reliable
  • Reduces your generator running costs
  • Warranty extension up to 25 years for grid tied invertors
  • Panels already come with a 25-year warranty

Disadvantages of Grid-Connected Solar systems

  • Dependent on the Grid availability
  • No Grid no production

Introducing generator PV coupling

When there is load shedding the generator automatically starts thereby switching the grid tied invertors then the production resumes

Generator coupled to PV solar, fuel consumption comparison

The table below outlines an approximation of the diesel generator fuel consumption per hour in litres. We have shown the usage at various load levels across a range of generators from 10kVA to 500kVA.Take note this table should only be used as an approximate to give you an indication of fuel usage at various load levels. Actual usage may vary slightly due to various factors.

Generator Size ¼ Load (litres/hr) ½ Load (litres/hr) ¾ Load (litres/hr) Full Load (litres/hr)
