What is solar power
Energy obtained by the Sunlight transformed into electricity using photovoltaic cells (PV), creates what we understand as solar power.
Typically a solar panel will start life as a 6” diameter blank of silicon around 18 inches in length. Silicon resin is used to create ingots quite literally in poly or mono moulding tanks.
The process manufacturing the silicon blanks is done in laboratories under strict hygienic conditions, (Clean Rooms). This is where the micro thin blanks are surgically machined.
These segments are then tested to obtain the relative ‘grade’ performance certification. The segmented parts of the silicon ingot are then assembled, and can then be called solar cells.
Photovoltaic or solar cells are manufactured out of polysilicon, or monosilicon, the cost of poly are usually less than mono, because it takes much longer to process. Therefore when you weigh up the performance differences the poly grade ‘A’ cell against the cost effectiveness of a mono grade ‘A’ solar cell, Differential costs tend to be minimal.
Electricity runs our World therefore it is an easy way to provide the abundance of electricity required, using photovoltaic solar PV panels, in assembled banks of cells, have the ability to turn light into voltage. Sun powered cells create a DC current.
When several cells are linked together this will increase the voltage across the circuit.
Solar modules are the finished article, this is what most people call a solar panel, these have no moving parts which reinforces the life expectancy of 25 years plus, historically most of the high grade ‘A’ equipment manufactured over the last 30 years in Germany is still generating power without fault.
Solar panel installations have reduced in price over the last three years. “This may have been due to some of the lower cost solar panels containing a lower performance cell.” Lower grade glass and frames, undoubtedly will not return the same consistent performance when this is based against the life cycle of a higher grade ‘A’ solar panel products. “The use lower grade silicon to manufacture the cells, could radically reduce the life expectancy of the finished product overall.”
Take a look at the picture, this shows a standard layout of a finished cell. These cells are so extremely thin that even blinking the wrong way could damage them. Therefore, it is important to understand the fragile nature of the products. The delicate nature of a completed product can be and the importance of selection.
