Tracking systems v Fixed Solar Panels for Off Grid Solar Power Systems

January 5, 2012

Tracking systems provide 30-40% more power but at a higher cost (often the same amount higher). So why use them? On an off grid system they balance the battery load because they are producing power for much more of the day.

Solar Tracking Systems – the best option for off grid power

November 27, 2011

LJW is an expert in the installation of remote power and stand alone power photovoltaic systems. Stand alone power systems often use a tracking system because it gives increased output by up to 40% compared to a fixed axis system. It also changes the pattern of production, by creating more power at the start and [...]

Solar Farms great for rural Australia

November 10, 2011

The increasing cost-effectiveness of solar energy could see more solar power plants established in regional Australia. The nation’s first utility-scale solar farm is under construction near Geraldton in Western Australia. Rob Bartrop, from developer First Solar, says decreasing set-up costs mean solar has become competitive with other renewable forms of energy. “A lot of smaller [...]

On Grid Solar Power v Off Grid Solar Power v Hybrid Power

September 28, 2011

On Grid Solar Most residences are attached to the grid, and draw their power in off the grid for use within the house. It is metered on the way in and you are billed for that power. When a solar power system is set up in this scenario it runs in parrallel exporting the power [...]

Glossary of terms for Solar Power – PV Systems

September 28, 2011

Alternating Current (AC) – The main grid and all of your electrical appliances run on AC. That means the flow of electricity constantly changes direction between positive and negative sides. Generally, mains current shifts direction at a rate of 60 times per second. (opposite of direct current or DC) Ambient Temperature – The temperature of [...]

The importance of solar trackers – great for off grid solar power

September 27, 2011

Solar trackers In most cases, solar panels are set up on fixed arrays – either on a roof or a ground mounted system. In cities, almost all solar is on household roof tops. A tracking system is somewhat more complicated to set up but allows the entire array to move throughout the course of the [...]

Flat v tilted panels – the importance of installation method

September 27, 2011

The ideal orientation of fixed panels is North, and the ideal pitch is around 30 degrees. The difference in output from this ideal is explained in this document. Grid_Connect_Design_Guidelines_CEC (skip to page 19 for Sydney data) You can see that facing East or West at a 30 degree pitch will lose around 16-18%. On a [...]

The effect of shading on solar panels

September 22, 2011

Being keen to ‘go solar’, a lot of people don’t realise (or are not told by their installers) the potential impact that shade can have on a system. Shade can have a massive impact on a system, decreasing output by 80% in some cases. Crystalline panels (so polycrystalline and monocrystalline) silicon panels are made to [...]
