Small Production Unit
This installation process has the principal of producing electricity exclusively for the sale of energy at a guaranteed or market rate. How does the Small Production Unit (SPU) work? The Small Generation Unit (SPU) replaces the previous micro and miniproduction systems. The PPU is installed at a consumer site and the energy produced is fully injected into the public grid (RESP). These SPU are regulated by the Decree Nº41/2019, 9th of October, altered by Decree Nº43/2019, 23rd of October, which defines the procedure for registration and certification order.
With the objective to reduce energy costs, solar pumping features are a special highlight in Donauer's work. Direct connection between pump and photovoltaic generator - without battery. A distinguishing factor is the maintenance-free operation, without fuel or lubricants and no risk of water pollution. Allows irregation in remote locations and this type of solution is adequate for any agriculture project, from small to big dimensions. There are other solutions for pool pumping, gardins, etc.
A monitoring system allows you to control the production of your photovoltaic installation. You can compare, analyse and display data from your photovoltaic solar energy system. Monitoring is essential to be able to make the most of the performance of your photovoltaic system, as well as detecting possible faults and/or malfunctions in advance.
A hybrid system is a electric energy production system which combines two sources of energy in once single installation. A hybrid system can be off-grid or grid connected. Usually, these systems use renewable energy sources, for example photovoltaic energy. These include control systems and bateries tp accumulate produced energy. It´s an excelent option for self-consumption systems.
Solar Energy Projects
We carry out solar energy projects. we advise and provide professional support - all over the world. Our solutions include planning, supply of high end material, logisitc support, start-up of the installation, and after-sale technical support.
Backup Solar Energy
Backup systems are not only used in regions without a power grid, they are also a great solution to avoid power failures in case of unstable grid or emergency power supply. These systems, called backup systems, are intended for private, commercial and industrial applications.
It is the ideal environmentally friendly alternative for isolated and off-grid locations. Isolated systems make a great contribution to the application of modern means of communication in remote areas and in regions without connection to the public power grid, also making it a great solution for basic neccessity issues. As It is aslo a technology that requires little maintenance. These systems can comnbine many energy sources such as solar energy and diesel generated eolics, which increases energy availability, reduces investment costs and allows greater efficiency with the different available resources. An isolated photovoltaic system should be carefully dimentioned and should offer maximum efficiency, reliability and flexible at an accessible.
