This post is excellent because it shows us the reasons why we should opt for the use of renewable energy and whose generation does not involve damage to nature. However, in some countries to opt for this photovoltaic system is highly expensive not all people can have this possibility although it would be ideal. I believe that the high costs in obtaining this system has to do with the interest of large companies because people continue to use only the supply of electricity they have as a way to generate a consumerism that keeps them and destroys the planet. It would be interesting that our friends PH engineers gave us some tips to make this system at home ourselves, well you know something like a "do it yourself" post. Thank you.
