Energy efficiency is an increasingly important issue due to the current scenario where increasing demand is growing faster than the energy supplied. It is important, therefore, analyze and minimize electrical system losses. This study conducts a comparison of a system formed by a photovoltaic generator feeding an LED lamp directly without steps DC-AC -DC conversion, and a system using these conversion steps for the same lamp power. Losses in conversion steps are quantified and the degradation of power quality occurred due to conversion is evaluated

Always seeking the maximum profit under the reduced production time and lower number of failures, companies are increasingly evolving and going after continuous improvement in order to remain competitive in the market. Thus, increasingly there is investment in the management system Lean manufacturing. Lean system is very important, because through it, the maximum value is added in the final product. Being measured by the efficiency and reducing failures to zero. In the studied company, Lean manufacturing system came into effect through the kanban system for purchasing, control and distribution of bulk material used in the assembly of the final product, which are earth-moving machines. It is very important to check the great change made in the company with the implementation of kanban. All inventory management becomes visual, elements are arranged in an organized manner, with addresses in structures, calculated in special boxes and finally, assemblers have the guarantee of an item supply, with the distribution cars located on their assembly area. This study participates effectively assuring the supply. Avoiding any failure on the lack of material, non-compliance of delivery times to the customer and maintenance of over-stock or obsolete inventory, in which case both cause financial loss to the company
