Photovoltaic power generation employs solar panels comprising a number of cells containing a photovoltaic material. The Australian Government provides incentives for the use of PVs for both domestic and industrial use you can save money, and save the environment.

Solar photovoltaics generates electricity in more than countries and, while yet comprising a tiny fraction of the GW total global power-generating capacity from all sources, is the fastest growing power-generation technology in the world.

Between andgrid-connected PV capacity increased at an annual average rate of 60 percent, to some 21 GW. A good EEI would be to measure current as a function of the angle of incidence of sunlight all within a short period of time eg 30 minutes ; measure current when collector is perpendicular to rays during the day how should that go?

If so, you could put a load on the circuit resistor and measure V and I. In the method shown below, Moreton Bay College students are measuring the effect of angle on the flow rate hence power output of a electrical water pump.

Energy output of a solar panel Photovoltaics (PV) is a method of generating electrical power by converting solar radiation into direct current electricity using semiconductors that exhibit the photovoltaic effect.

This was Year Energy output of a solar panel II You could also investigate the effect of shade on the output of a panel. In this photo, students are using layers 1, 2, 3 etc of shade cloth. It would also be interesting to see the effect of light of different wavelength to see if the solar cells are sensitive to all wavelengths.

java - Temperature Conversion Class | DaniWeb Sir William Thomson 's third tide-predicting machine design, —81 In the first half of the 20th century, analog computers were considered by many to be the future of computing. These devices used the continuously changeable aspects of physical phenomena such as electricalmechanicalor hydraulic quantities to model the problem being solved, in contrast to digital computers that represented varying quantities symbolically, as their numerical values change.

You could use coloured cellophane - but then that reduces intensity and not all coloured cellophane has the same percentage transmission.

For large-scale solar plants to maintain their maximum efficiency, the photovoltaic cells must be kept clean, which can be a challenging task in dusty environments. One good EEI would be to investigate the effect of dust on the solar panel.

This is a harder EEI than the two above. It involves setting up a solar panel a short distance from an incandescent bulb eg 15 cm and adding controlled amounts of "dust" eg bentonite clay powder, fine sand, icing sugar to the face of the panel spread evenly.

It is a good idea to adjust the panel so it is working at maximum power. Do this by setting up the circuit on the left below, using either a variable resistor or fixed resistors that can be varied from 0 ohm to ohm.

Plot a graph next figure to see the maximum power point. Then add the bentonite 0.

A good article is in Physics Education, V45, Septemberpage Solar panel output and temperature The output of a solar photo-voltaic PV panel changes during the day for two reasons: I have 16 Suntech panels.

Any cloud cover on these days seems to help output a lot also. I have got I also have black tiles but have a good 50mm gap between roof and panels so it should have reasonable airflow.

This suggests a good EEI. Then with constant illumination, you could put the PV panel on top of a hotplate and crank up the temperature.

How high a temperature - well, you can decide.

Alternatively, you could hold the temperature constant and vary the illumination. Year 12 student Ryan Phillips from Villanova College, Brisbane, used an electric bar heater in front of the solar panel.The history of computing hardware covers the developments from early simple devices to aid calculation to modern day computers.

Before the 20th century, most calculations were done by humans. Early mechanical tools to help humans with digital calculations, such as the abacus, were called "calculating machines", called by proprietary names, .

Bill Hennessy. Great things that people love. This is the website of consultant and writer William Hennessy. Getting all the facts sounds sciencey.

People who forgot fifth-grade science class forget how the scientific method begins. The scientific methods begins with observation. A technology called NTX actually blocks the liver-killing.
