A 9.9kW solar system for homes in Wollongong is becoming increasingly popular amongst Australian homes as a result of a number of factors, including their affordability, their size & ease of approval when it comes to connecting to the grid. If you’re considering a 9.9kW solar system for your home in Wollongong, the following things should be kept in mind like pricing, energy yields and their attractiveness as an investment.
How many panels are required in a 9.9kW solar system for a home in Wollongong? How much area required?
A modern-day 9.9kW solar system using 370W panels will consist of about 27 panels.
Each panel generally measures out to about 1.7m2, so the roof area required for a 9.9kw solar system for a home in Wollongong will be about 37-40m2 – or possibly more depending on how your roof is laid out and whether you require tilt frames (which need to be spaced out more than panels mounted flush on the roof).
An important note about inverters for 9.9kW solar system for home in Wollongong
9.9kW solar system for homes in Wollongong are the latest systems.
Although a 9.9kW solar system for a home in Wollongong may have 9.9kw worth of solar panels, don’t be surprised if the proposed inverter for your system is only 8kW or 8.5kw. 8kW solar systems are also incredibly popular in Australia for a number of reasons (including the fact that that size is pre-approved for grid connection on basically every network in the country), which means that 8kW inverters are much more common to come across. Many of the 9.9kw solar system for home in Wollongong on the market are therefore ‘overclocked’ systems with an 8kW inverter. This is perfectly legitimate within Clean Energy Council guidelines, with benefits such as greater solar energy yields in early morning and late afternoon – even if ‘peak’ production is clipped back to 8kW during the middle of the day.
How much does a 9.9kw solar system for a home in Wollongong cost?
Solar Choice has been keeping track of residential solar system prices since August 2012 with our monthly Solar PV Price Index.
The cost of such a 9.9kw solar system for a home in Wollongong is around $4000-$5000 – significantly less than what it would have been even just a few years ago.
The price of solar systems do, however, vary widely in the market. A more cost-competitive 9.9kw solar system for home in Wollongong consisting of cheaper, low-end products will cost less, while premium offerings will generally be pricier.
How much energy will a 9.9kw solar system for a home in Wollongong produce?
Depending on a number of factors, the actual power output of a 9.9kw solar system for a home in Wollongong will vary. These variables include:
- Location and local climate
- Orientation and tilt angle of the solar panel array
- Whether there is any shade cast on the panels.
- The performance of the individual components (primarily the panels and inverter)
Location is one of the main determinants of solar system energy yields, as the amount of sunshine falling on a solar system’s solar panels directly affects the system’s output.
