Brisbane is dubbed as the sunshine state capital because of the 5.5 hours of peak sunlight average per day, according to PVWatts. But what do 5.5 hours of sun really translate to?
A great investment
A good quality solar power system installed properly and working efficiently will definitely yield savings at large. A 3 kW sized panel returns your investment by means of savings in 4 years, and $1,100 annual savings thereafter. How is this possible?
Abundance of sunshine
For a residential solar panel in Brisbane that is 85% efficient and north facing, a 1.5 kW sized system can yield 5.8 kWh daily. The bigger the size goes, the more output it generates. A 2 kW solar panel generates 9.4 kWh per day, 5 kW sized panel yields 23 kWh per day, and a 10kW solar panel can generate an output of 47 kWh per day. But what do these figures really mean?
Electric bills always indicate the power usage of the household in standard unit kilowatt-hours (kWh). This varies by season and by month, so it would be wise to study one’s power consumption pattern. With this, it would be easy to figure out how many kWh a household consumes on a daily average, and this will help with deciding the best size of solar panel to pick.
Solar power system prices and installation
Australia solar system prices for installation is among the lowest worldwide. And a number of companies offering solar power in Brisbane offer competitive prices. The federal government also provide discounts on installations through Australia’s RET or Renewable Energy Target. The value of the discount or incentive is subject to several factors, like system size and location, but is usually 30-40% off the installation cost. This incentive in place makes the country home to the world’s lowest solar power system prices. For the actual equipment, cheaper panels do not necessarily mean lower quality but always research on the brand you are eyeing and proceed with caution. Maintenance require inverter replacements every few years and the product warranty is usually 25 years.
In order to ensure uninterrupted power service, a battery storage system is necessary, so you can still have solar electricity available even at night. Companies offering systems for solar power in Brisbane made battery storage systems affordable as well.
