We briefly mentioned the term ‘photo voltaic’ on the How Solar Power Works page of this site. Here we take a deeper look into what really is behind this effect and how it is the backbone of solar panel function and operation. The development of ‘photo voltaics’ – the process of converting the sun’s visible spectrum radiation into electricity has come a long way in the last 20 years but much of the ‘credit’ for the development of the underlying principles of solar cell operation go back further than that – to the pioneers of modern day quantum physics. Physicists like Planck and Schrodinger were credited with much of the initial work around quantum physics which was a model that attempted to describe the behaviour of electrons within atoms and more particularly the way the atoms moved in discrete energy levels or ‘quanta’ of energy. This discovery, at least in basic terms, demonstrated that when electrons were ‘excited’, by, for example in the case of solar radiation, sunlight striking a suitably modified piece of silicon, that the electrons within that material would experience an ‘increase’ in their energy levels by a very specific amount. This amount of increased electron energy was not a ‘randomly defined’ amount of energy but, to the contrary, was found to be determined by quantifiable ‘steps’ of energy. Einstein was the first to discover and document this ‘photo-voltaic’ effect, which became the cornerstone of the modern day solar panel. The video below gives a reasonable explanation of the photo voltaic effect in silicon – the most commonly used semiconductor in solar panels:

Living in Canberra? Talk with your LOCAL Solar Power Installation Company We work hard to provide very prompt, courteous and above all, skilled levels of customer service to our clients. If you are confused about how solar panel installation can cut your power bills talk to us today. We can explain in clear, easy to understand language, what the current A.C.T. feed in tariff is and how to optimise and get the maximum benefit from your solar panels.
Premium Quality Inverters
We supply only the best brands of solar panels, cabling, inverters and racking systems.
- Warning -Electrical Components:
Installing cheap electrical parts will decrease the solar system cost but it may considerably decrease the efficiency of the system, its life and safety. This is why we only install high quality components. An example of this is that we only use 1000v lockable isolators and not the conventional circuit breakers.
Extensive Choice Of Panel Brands
We carefully tailor the type and brand of solar panels to your situation, budget and installation parameters. We carry only reputable, tried and tested brands like Sharp, German Solar, LDK, Trina and many more. As discussed, our philosophy is that we will only carry and install solar panels with solid, long standing back-up and support. Call us today for a totally free appraisal of solar power for your home.
