What is the difference between software engineering and traditional engineering?
Difference between software engineering and traditional software engineeringSoftware engineering is based on computer science, information science and discrete mathematics whereas traditional engineering is based on mathematics, science and empirical knowledge.Traditional engineers construct real artefacts and software engineers construct non-real(abstract) artefacts.In traditional engineering, two main concerns for a product are cost of production and reliability measured by time to failure whereas in software engineering two main concerns are cost of development and reliability measured by the no. of errors per thousand lines of source code.Both disciplines requires maintenance but in different ways.Software engineers often apply new and untested elements in software projects while traditional software engineers generally try to apply known and tested principles and limit the use of untested innovations to only those necessary to create a product that meets its requirements.Software engineers emphasize projects that will live for years or decades whereas some traditional engineers solve long-ranged problems that ensure for centuries.Software engineering is about 50 years old whereas traditional engineering as a whole is thousand of years old.Software engineering is often busy with researching the unknown(eg. To drive an algorithm) right in the middle of a project whereas traditional engineering normally separates these activities. A project is supposed to apply research results in known or new clever ways to build the desired result.Software engineering has first recently started to codify and teach best practice in the form of design pattern whereas in traditional, some engineering discipline have thousands of years of best practice experience handed over from generation to generation via a field's literature , standards, rules and regulations.

Do solar panels last more than 50 years?
Depends on the quality and how you treat solar panels. Generally, solar panels normally last from 20-30 years treated well enough, but for 50 years, you need to get a REALLY good quality solar panels. Average solar panels, last for about 20 years. Good panels can last for 50 years, but that is hard.
