Worldwide, government policy has distorted demand and supply in the global photovoltaic industry for many years. 2013 is already seeing changes in some of those distortions. To determine how this translates to solar power systems’ pricing in 2013 we need to look at basic economics – price is set where demand equals supply. A History of…
Sunlight is converted to DC (direct current) electricity using the silicon and other chemical elements within the solar panels (PV array). The DC current runs down the electrical cabling to the inverter. The inverter transfers the current from DC to 240 volt AC (alternating current)- so that it is suitable for use in your home.…
In Perth, WA the ideal position for solar hot water system panels or solar power panels is facing true north on a 30 degree pitch.
As there are so few moving parts there is not much involved in maintaining your solar power system other than cleaning and inspecting the system. Solar Panels Cleaning Dirty panels reduce the amount of sunlight absorbed, and thus the power generated. It is advisable that you wash your solar panels at least once a year…
A solar panel should be designed to last at least 25 years, so build quality is an important factor in choosing a quality solar power (photovoltaic) system. To make a solar panel, solar cells are laid between a superstrate layer (usually glass) on the top and a backing sheet (usually plastic laminate)on the bottom. This…
Should I choose the cheapest brand of photovoltaic system that provides a decent warranty? Unfortunately it is not that simple. As always, it pays to read the fine print for what is and isn’t covered by warranty. Also, if there is a warranty call, determine who is going to replace the faulty part. Plenty of…
So you are looking at solar power systems and you want to know which one performs the best To understand the performance of solar power (photovoltaic) systems you need to look at the panel and inverter specifications. Inverter Performance Most people concentrate on solar panel performance and forget about inverter performance. But what’s the use…
On Friday 16 November 2012, the Australian Government announced that the Solar Credits multiplier on small scale solar power photovoltaic wind or hydro systems will cease 1 January 2013. This brings forward the date 6 months as it was due to cease 1 July 2013. Effectively this means that from 1 January 2013 the only…
