Write a term paper about: 
1.   The  battery  system  price  investigation,  including  all  kinds  of  battery  types  such  as lead“acid and lithium“ion (LI), etc.
2.   Consider  the  solar  +  battery  system  to  meet  part  of  the  energy  demand  for  all  the buildings. Find out the initial price, the annual benefit and costs for the solar + battery system. Assume a time period, could be 10 years or 20 years, use the knowledge from this  class  to  find  a  better  choice.  Three  scenarios  with  30%,  50%  and  100%  of  the energy demand covered by solar + battery system are the alternatives.
