We can divide solar panel applications into 2 types: standalone systems grid connected systems Grid connected systems has been expanding rapidly since 1990. One driver for this is government rebates and incentive schemes. Standalone PV Systems Standalone photovoltaically powered systems can be small with peak PV power in the milliwatts to large, with peak PV [...]

Solar panels are made of silicon, the second most abundant element on earth behind oxygen. However it is mostly found in oxidized form such as silicon dioxide, sand or quartz. In the refining process, carbon and SiO2 is heated to 1800 degrees. This results in 98% pure silicon and as such is not suitable for [...]

Back in ’94ish, I participated in the World Solar Challenge as part of a TAFE team. It was a very low cost, low tech entry, basically it was a fiberglass canoe shape body with two wheels at the front and one at the back. A big flat solar panel array above our heads which could [...]
A V trough solar concentrator array would look like the below, not shown is the solar tracker. This particular array has a 60 degree concentrator, with the reflector surface the same length as half the width of a solar panel. The yellow lines represent the sun and show the sun reflecting to the middle of [...]

A solar concentrator is a shiny surface that reflects sunlight on to a collector. One type of concentrator is a ridge or V trough In this diagram, the solar panel is 50mm wide, the angle of the reflector trough is 60 degrees and the reflector trough in 50mm. You can use the solar funnel calculator [...]
