Commercial & Industrial Solar Energy & Battery Storage Solutions
Commercial Applications of Photovoltaic Grid Connected Systems
Medium and large industrial and commercial businesses can make effective use of photovoltaic (PV) electricity because solar generation generally matches load usage. ‘Medium’ consumers of electricity are those who use less than 275 kWh per day. The size of the selected PV system depends largely on the daily consumption.
For example, a 10 kW PV inverter system will generate on average 45 kWh/day with 10-20% more in summer and 10-20% less in winter.
‘Demand Charge’ Fees
Large consumers who use more than 100,000 kWh per annum must pay demand charge fees on a kW basis in addition to their kWh energy usage. This charge usually amounts to no less than $1500 per month on top of their consumption and service fees.
Photovoltaic generation can help reduce maximum demand charge (kW) 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. 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.

Commercial & Industrial Businesses are Reaping Savings from the Sunshine
Any business investment MUST make you money or make your life easier. Installing solar does BOTH. Payback and return on Investment certainly stacks up in today’s environment. More and more businesses are discovering just how effectively solar drives down their outgoings. Large businesses with access to the best and brightest accountants, analysts and managers are leading the charge.
Companies such as the supermarket chains, department stores, logistics complexes, hardware chains, giant tech companies, manufacturing plants, together with institutions like private schools, universities and colleges - plus more and more government agencies. The people running these undertakings are quietly enjoying the satisfaction of positive impacts on their profitability and often kicking themselves for not joining the renewables revolution sooner.
