Project Description

Commercial Grid Tie Solar

No matter how streamlined you try to operate your business you can feel the pinch in your profit margins with electricity prices rising steadily for years now at a rate never imagined before.

Many commercial businesses are looking for ways to reduce their energy costs and a commercial grid connected solar PV system which is well matched to your company’s usage patterns in sunshine hours could be a solid contribution in your aim to cut operating costs.

To get the best ‘bang for your buck’ it is of great importance to collect information how you use your Energy right now in your business. As your feed in tariff with any retailer may most likely be only 4 to 6 cents per kWh fed to the grid, the most ideal solution is to offset as many kWh of energy regularly used into ‘Peak Sunshine hours’ – hence instantaneous use of your free sunshine power.

Below is an example of a business we modelled for 2 systems around the 20kW size investigating the outcomes of placing the panels flat to the roof (pitch 10°) facing East, as the building was built that way (Table A) and tilted with special frames North 15° pitch (Table B).Due to the nature of the business – metal fabrication, the starting hours are early not quite fitting to the ‘Peak Sunshine hours’.

For this reason we stress how vital it is to gather usage information. These can be obtained by contacting your retailer and requesting more detailed consumption reports or by contacting us to clamp up your main phases and connect it to a meter for a period of time to collect data (fees apply to this service) or read your meter(s) from the start of operational hours to the end of operational hours every hour to for 1-2 weeks to establish your usage patterns.

The possible saving outcomes have been demonstrated to the customer based on an electricity cost of 20 cents per kWh used (based on a 20kW system).
