Solar power cannot be made competitive by spending more money hiring more scientists and conducting more research to find a technological breakthrough.
Are solar panels efficient or inefficient.
And 20 isn t that bad actually.
Solar panel efficiency is a measure of how much sunlight that hits the surface area of a solar panel is converted into usable electricity.
Please note the caption on the above illustration assumes unlimited progress in technology.
When it comes to specific answers to the question if the solar panels are inefficient or not the answers are unclear and it s still up to debate.
So the question that arises is does solar panel efficiency matter.
The wind and sun are free resources.
In other words solar is efficient enough.
This means that a 14 percent efficient solar panel will be bigger in size.
Factors that affect solar panel efficiency.
The efficiency in other words.
Solar energy is similarly inefficient for other uses of fossil fuels.
So if a solar panel has an efficiency rating of 15 that means 15 of the sunlight that hits the solar panels will be converted into electricity.
Most solar panels are between 15 and 20 efficient with outliers on either side of the range.
Solar panels have been consistently increasing in efficiency at about 5 annually since 2010.
In theory pv cells should get more and more efficient as light concentration increases.
The difference lies in the size of the panel lower efficiency panels require more space to produce the same power output.
In other words if you double the light intensity it should more than double the.
The amount of space the panels need to make the amount of power needed is perfectly adequate for making enough power to meet the average homeowner s needs.
In some applications like solar cars satellites lighting and electronic devices size will matter as the space availability is limited and each inch of the panel needs to produce the maximum.
There are far too many variables that can affect the efficiency of solar panels which can both be taken as benefits or dangers.
It works 100 to do the job we need it to do.
With solar panels this is around 20 but the 80 isn t an expensive waste.
The highest efficiency solar panels on the market today can reach almost 23 percent efficiency.
The average efficiency of solar panels falls between the 17 to 19 percent efficiency range.
High quality solar panels can exceed 22 efficiency in some cases and almost reach 23 but the majority of photovoltaic panels available are not above 20 efficiency.
