Thumbnail image for Residential Solar PV Price Index – November 2017

We’ve introduced some major improvements to this month’s Solar PV Price Index. Namely: We’ve added 7kW solar systems to all tables We’ve included in new tables & data for ‘premium’ and ‘microinverter’ system offerings We’ve drawn clearer distinctions between ‘primary’, ‘premium’ and ‘microinverter’ pricing We’ve dropped 1.5kW systems from our data tracking (because so few […]

Microinverters: Are they right for your solar system?

April 18, 2017
Thumbnail image for Microinverters: Are they right for your solar system?

As the name suggests, microinverters are small inverters for use in solar PV systems, usually installed at a ratio of one per solar panel. By contrast, most solar PV systems in Australia have a single, centralised inverter called a string inverter. What are the advantages of having a solar PV system that uses microinverters instead of […]

How does maximum power point tracking (MPPT) work?

March 27, 2017
Thumbnail image for How does maximum power point tracking (MPPT) work?

Maximum Power Point Tracking (MPPT) is a technology approach used in solar PV inverters to optimise power output in less-than-ideal sunlight conditions. Most modern inverters are equipped with at least one MPPT input. The below article – which originally appeared as a response by Bradley Detjen to a question on Quora.com – explains MPPT using the most […]

Sizing inverters to optimise solar panel system efficiency

February 6, 2017
Thumbnail image for Sizing inverters to optimise solar panel system efficiency

The efficiency of the inverter drives the efficiency of a solar panel system because inverters convert Direct Current (DC) (as produced by the solar panels), into Alternating Current (AC) (as used by the electric grid). This leads many to wonder what effect over-sizing or under-sizing an inverter will have on overall system efficiency. This entry […]

Should you oversize your solar array / undersize your inverter?

February 3, 2017
Thumbnail image for Should you oversize your solar array / undersize your inverter?

After numerous questions about the relationship between solar panel power and inverter power, I decided to put together this blog post. Now logically, if you have (say) 3,000 Watts of solar panels on your roof, you would expect that a 3000 Watt inverter would be the perfect match, right? Not necessarily! There are a number of […]
