A 20kW solar system is very often a smart investment for small to medium sized businesses looking to reduce their operating costs by powering their daytime electricity consumption from solar power. This article will provide a brief overview of the price of a 20kW solar system, potential power yields (in kWh), and financial returns that a business may expect.
Inverter: The choice of inverter will depend on a number of different factors. Often we will install a number of smaller inverters to maximise flexibility with panel design. We sell the leading models from all of the largest manufacturers including SMA, ABB (Aurora) and Schneider Electric to name just a few.
Mounting Kit: Solaray can design a mounting solution for almost all roof types. The two main exclusions are asbestos and slate roofs.
As a general rule, a 20kW solar power system will output around 80kW/h a day averaged out across the year.
There are a number of factors that influence this figure and these include:
- The location of the system and the expected daily and annual solar irradiation and cloud cover
- Orientation of the roof and the tilt angle of the solar panel array
- Whether there is any shade cast on the panels. For roof with patchy shade we recommend a micro inverter system.
- Operating temperature of the panels - it is important to use good quality panels with temperature coefficients well over 40 degrees.
- Whether solar panel array capacity is professionally matched to inverter capacity. This is an important design consideration and our commercial team can discuss this with you in more detail.
- The quality of the individual components. For example, a Q Cells panel may outperform a cheaper Chinese Made panel by 5% or more. This can result in a large difference in potential savings when extrapolated out over a year... or a decade.
A 20kW system installed in Sydney with no shade orientated north can generate up to and even over 100kW/h a day in summer. In winter, when the days are shorter and the sun is lower in the sky, a 20kW system may only produce 60kW/h a day. When you make an enquiry, our commercial solar team will ask you for a number of power bills to analyse when your business uses its power (both across the day and across the year) to accurately size up a solar power solution.
Financial Benefit of a 20kW Solar System in Sydney
A commercial solar power system in Sydney directly reduces your power bills by feeding solar power directly into the main phase of your power supply. Because of this, the potential savings of a solar system depend on how much you pay for your electricity.
As a rough guide, a 20kW solar system will save you up to approximately $8,800 (this figure will change depending on the price you pay for electricity). For more information please contact our commercial solar team.
With a possible return on investment now well under 5 years, a 20kW solar power solution is now an attractive investment option for your business to reduce short to medium term operating costs, and to improve the environmental profile of your business.
