Solar panel cost is based on what?

Many factors have direct effect on solar panel cost. First is the power size (in Watts), than the physical size, the brand, the durability and quality certifications it might have. Deciding only on solar panel cost is not recommended; because it may not fit the area you wish to install it. Next problem could be that it doesn't have the necessary certifications to qualify for government rebates, or may not have the durability required for economic payback of the power produced.

Durability and Warranty The durability or longevity of the system is important for a number of reasons. For example, if the solar panel only has a 10-year warranty and it is used in a grid connect system you would expect it to produce enough power to pay for itself within 10 years. But if that is not the case than hardware cost will go up sharply. So to make most of your system you should go for quality, long lasting plates. Reputable manufacturer will have warranty period of 25 years.

Size and Watts The producing power of the solar panel in Watts will directly affect the price, as they are usually priced (and compared) in dollars per Watt. Watts are related to the output of each panel, which means that a 100Watt unit under ideal, sunny conditions will generate 100 Watts of electricity each hour and a 200-Watt unit will produce double. That is why you can expect to pay double price for the 200-Watt panel, compared to the 100-Watt one.

The output is directly correlated to the physical size of the panel, which means that the 200Watt unit will take much more space than the 100-Watt one. . The type of solar cells that produce power also has great impact on the size of each peace. Main thing to consider is that your system overall make enough Watts to power your appliances, but at the same time that the hardware will physically fit in the area you wish to install them. Both these factors will have direct impact on solar panel cost.
