Answer to Question 1

Both systems can reduce the electrical requirement at a home or business. A grid-tie battery-backed system can have autonomy from the grid in case it goes down, which can provide emergency power; a system without battery backup cannot. The battery backed up system requires higher initial expense, ongoing maintenance costs, and a dry space that is well ventilated for batteries, whereas this expanse is avoided in a non-backed up system.

Answer to Question 2

A receiver at the top of a tower is heated by heliostats which direct sunlight to the receiver. A heat transfer fluid is used to produce steam, driving a steam turbine and generator. Hot, molten salt can be stored to allow electricity to be generated when there is no sunlight available.

Every flu season is different, and even healthy people can get extremely sick from the flu, as well as spread it to others. The flu season can begin as early as October and last as late as May. Every person over six months of age should get an annual flu vaccine. The vaccine cannot cause you to get influenza, but in some seasons, may not be completely able to prevent you from acquiring influenza due to changes in causative viruses. The viruses in the flu shot are killed—there is no way they can give you the flu. Minor side effects include soreness, redness, or swelling where the shot was given. It is possible to develop a slight fever, and body aches, but these are simply signs that the body is responding to the vaccine and making itself ready to fight off the influenza virus should you come in contact with it.
