1) Using portable panels is much more efficient, if you keep them aimed toward the sun every couple 3 hrs.
2) If you perm mount them on roof, figure on at least double to triple the panels.
3) Storing/hauling port panels is always a problem unless you have large basement compartments, or carry them inside.
4) Don't get caught up in all the hi $ sofistigated equipment, unless you are a real solar fanatic.
5) Panels at $1.50 per watt max, and a $15 controller works great for me. Add a 100 ft roll of 10ga twin lead wire ($36) to connect it all, and you're in business.
