Solar Panel Efficiency Rating 2015

What you need to know.

Solar panel efficiency rating 2015. Solar panel efficiency is a measure of how much sunlight that hits the surface area of a solar panel is converted into usable electricity. The solar industry today looks very different. Solar panel efficiency is a measure of the amount of solar energy irradiation which falls on a panel surface and is converted into electricity due to the many recent advances in solar cell technology over the last 5 years average panel conversion efficiency has increased from 15 to 20. What you want to know about solar panel systems.

Solar cell efficiency refers to the portion of energy in the form of sunlight that can be converted via photovoltaics into electricity by the solar cell. A tale of falling prices. The average efficiency of solar panels falls between the 17 to 19 percent efficiency range. Solar panels have been consistently increasing in efficiency at about 5 annually since 2010.

The general consensus was overwhelmingly in favor of one main feature. Cost of solar panels over time. The panasonic n series of panels are a good quality solar panel with a top efficiency on their 330 watt monocrystalline system of 19 7 and a very impressive temperature coefficient of 0 29 a figure which is equal best with the market leader sunpower. Factors that affect solar panel efficiency.

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. In addition to solar panel efficiency increasing dramatically solar panel producers have significantly improved their manufacturing processes. The efficiency of the solar cells used in a photovoltaic system in combination with latitude and climate determines the annual energy output of the system for example a solar panel with 20 efficiency and an area of 1 m 2 will produce 200. Solar panel efficiency is a measurement of a solar panel s ability to convert sunlight into usable electricity.

The most efficient solar panels commercially available today have solar panel efficiency just under 23. Over a decade ago in 2009 the cost of a solar panel installation was 8 50 per watt. The graphic below shows how dramatically solar panel performance has improved over time. A higher solar panel efficiency rating means a panel will produce more kilowatt hours of energy per watt of power capacity.

What is solar panel efficiency. We conducted a survey among over 1 000 respondents ages 35 and older and asked them what they felt was the most important quality a solar energy provider could offer them as consumers. Outside of manufactured factors like efficiency power ratings and degradation rates there are a variety of external factors that can affect the performance of your solar panels.
