‘On Grid’ Photovoltaic Systems
Medium and large agricultural operations can make effective use of photovoltaic (PV) electricity because solar generation generally matches load usage. Photovoltaic generation can help reduce maximum demand charge (kW) – for customers using 100,000 kWh per annum – as well as the energy usage (kWh). When the contribution of PV electricity reduces the annual consumption of grid electricity below 100,000 kWh the consumer can apply to change to a different kWh only tariff. For such customers this results in 40-50% reduction on energy bills.
A reasonable sized PV system is 36 kW connected to one or two inverters. The energy generated averages 140 kWh per day depending on tilt angle and orientation.
Off Grid Photovoltaic System
‘Off grid’ solar systems for electricity generation employ a PV array, a storage battery and a stand alone inverter. A maximum power point tracker is used to optimally charge the battery bank. The ‘off grid’ system usually incorporates a backup diesel or petrol generator.
During the day energy can be used to supply the day load and the excess energy is stored for use by the night load. Either lead acid or lithium batteries are used at a D.C. voltage of 24 V or 48 V depending on the inverter capacity. Higher D.C. voltage is preferred if the connected load exceeds 3 kW to reduce internal resistance losses.

The Solar PV Design Process Begins
At Solar Energy & Battery Storage Solutions (SEBSS), we guide business owners or managers through every step of the process, helping you to understand solar basics, analyse your power needs, and explaining the opportunities available to you.
Paul & Kame begin with a feasibility study for your business based on an on-site analysis and scrutiny of your power needs and past and current usage. We can interpret your past 12 months of electricity usage data from your meter right down to 30min intervals. This, with a survey of your available roof space, allows us to recommend the right sized solar system for your situation.
An over-sized solar system is over-capitalising and a waste. On the other hand, under-sizing can mean a lost opportunity for very high marginal returns on the electricity your system generates. Read more: Investing in Solar
