Manufacturers can make solar panels more efficient in two basic ways.
Are more solar panels more efficient.
The more efficient the photovoltaic solar panel the more energy output it will have per amount of light energy hitting the cell which will in turn take up less surface area to meet your energy requirements.
As a result these panels tend to cost less than the more efficient monocrystalline panels.
Reflectance efficiency is determined by how much sunlight is reflected back instead of absorbed and put to use.
Solar panel efficiency is a measurement of a solar panel s ability to convert sunlight into usable electricity.
Improving the solar cells themselves improving the way the cells are placed in the panel there is an alphabet soup of acronyms and buzzwords being floated around about improvements in technology coming down the pipeline.
Oxford pv claims that the next generation solar panels will be able to generate almost a third more electricity than traditional silicon based solar panels by coating the panels with a thin layer.
Right now sunpower manufactures the most efficient panels on the market the series x which boast a whopping 22 8 efficiency rating.
Given the same amount of sunlight shining for the same duration of time on two solar panels with different efficiency ratings the more efficient panel will produce more electricity than the less efficient panel.
