The decision should not be taken lightly because it depends on the efficient functioning and durability of an installation of photovoltaic panels. Then briefly detail my analysis of both possibilities through the search and study of the options available on the Internet. Buy solar panels used. This seems the most logical choice to rule after the purchase of new panels. There are a variety of prices, brands, and qualities that allows choosing the most appropriate to our needs.
It's great that there is this wide range of offerings, but on the other side may be a degree of complication. It is necessary to know the technical basis for solar power generation to make a good choice and purchase. Avoid being led by a great price without checking carefully the operating status of the panels. Construction of solar panels. It may seem odd, but to build solar panels do not need to be technical. These devices are surprisingly simple and there are many manuals, guides and instructions available for construction. The great advantage is that a homemade panel is built with new parts at a price much lower than that of a panel used.
The downside is obvious, it takes desire and some time to undertake this work. My decision. I prefer the new products, especially for electrical devices, because of that and the low costs involved, I decided to build my own solar panels. I would like now to share the results of my search, hoping that this information is useful for those who want to switch to clean energy and significantly reduce their energy supply costs. In the link I put down is a good summary of what is in my opinion the best choices in terms of self-built photovoltaic systems. It is a professional guide with step by step videos designed for anyone to follow instructions, no matter the lack of expertise or level of English.
