Italian Salesman

The sales person who came to check out my roof garden is an Italian guy.  It is interesting.  His boss is from China.  I think I spoke to his boss many years ago with regards to solar water heater.  He also propose a much larger system.  I am thinking I may need a smaller system to have lower capital cost plus I like some open space for my roof garden.  I will wait and see how much he quotes and then write to the relevant authorities to make sure I am in compliance with the law.  I like the fact now I can really be green.
