Solar Panel Prices -- A guide to give you an idea of how much they cost
Factors affecting solar panels prices
In an obvious way, different solar cell's costs are different. We can see that the prices wary depending on the working age of the cells, the quality of the material they were made in and the machinery they were constructed with. It is essential to note that as with every other aspect considering technology, the newest cells are the best since they have been manufactured by breakthroughs in efficiency and maybe cheaper to produce materials, hence affecting both quality and performance in a better way. Hence the solar panels prices may vary.
If you compare two different panels which have been in use for, say 1 year and 20 years, the prices may vary because of the varying technology and the age of the panels.
In short, thought two solar panels may be similar, many factors still need to be taken into consideration. It is to be duly noted that you cannot buy a cheaper alternative just depending on its price, the focus should be more on efficiency and the amount of energy harnessed.
Comparing the prices of solar panels
Measure the dollars/watt ratio to compare the value of two solar cells. The best deal you can currently get on solar cells is about $4.30 per watt. Your total cost for a 50 watt solar panel would be $215. Remember this when calculating the cost and buying solar panels and cells. A complete set of solar cells is known as a solar panel, hence solar panels prices are derived from solar cell prices.
The newer panels in the market are not always cost effective, so you should judge the working of a system on its dollar/watt ratio, even if you are planning to choose the latest system or even trusty older ones.
Scrap solar cells
The defective solar panels (the ones which may vary from tiny defects but are still in working condition) which do not go through the quality checks can be bought from scrap dealers to be utilised at as less as $3/watt. So it will be a massive bargain for clever buyers but you may lose out on quality so make sure to check the panels first. Solar panels which are defective can be bought online from various dealers. You can get a bargain between them too!
