Photovoltaic: A simple technology with huge effects
The functional principle of photovoltaic was discovered by a French physics called Alexandre Edmond Bequerel. Initially in the middle of the 20th century photovoltaic technology was initially used in the field of cosmonautics. Since then, many things have changed. Nowadays solar plants are profitable investments and affordable for everyone.The technology is simple. No matter if you invest in an open space solar park or roof-top installation, the construction is the same. Solar photovoltaic modules are assembled on a mounting system which is either fixed on a roof or on the ground. Solar photovoltaic modules generate direct current (dc) through solar radiation.
DC is transformed to alternation current (ac) by inventors. The ac is then integrated either into the public grid or is used by you. Both ways are attractive for you because you earn money with either way.
Solar photovoltaic module – the heart of your PV-system
Solar radiation is converted into electric power by a solar photovoltaic module. Each module is made up of many solar cells. Cells can be differentiated into thin-film and thick-film cells. In general it can be said that thin-film modules are more affordable with the compromise in lower power output. Thus, we evaluate on a case-by case basis, which solar photovoltaic modules are economically reasonable for your solar installation.The prudish cells are embedded in a transparent-, radiation- and weather-proof membrane. On top, a glass panel secures and protects the cells from mechanical forces and the elements. The quality of the embedment is crucial for the long-lasting quality guarantee of the solar photovoltaic module. As the temperatures rise, there is a possibility of declinining effectiveness of the single solar cells. This is avoided with the integration of a specially optimized into the module that gurantees optimum cooling of the solar cells. The solar photovoltaic is framed in an aluminum frame. The frame is needed to secure the glass panel during transportation. Handling and assembling is easier with a frame. The frame hardens the connection between the single cells and last but not least the frame is needed for the fixation of the solar photovoltaic module on the mounting system.
The production of solar photovoltaic modules requires expertise and a commitment to quality manufacturing. For this reason, we only partner with carefully selected suppliers; with the promise of a high return on investment while delivering the highest quality.
The Alternating-Current Inverter
Solar photovoltaic modules produce dc where as the public grid runs with 50Hz 230 ac. The task of the inverter is to convert the dc into ac to induct the power into the public grid. Additionally the inverter shuts down the solar installation if grid problems occur, to avoid overvoltage and damage to your solar installation.In regard to invertors we put our trust in high-quality German products. The invertors we use achieve an efficiency rating of 98%.
Always stable – no matter what the weather is like.
No matter which type of roof or open space installation you need. ENVALUE uses customized mounting systems in order to optimal utilize and secure available space and to serve the needs of our customers and investors. In order to position modules optimally, ENVALUE elevates solar photovoltaic modules on flat roofs or roofs with a small slope. Thus snow and debris disappear and your solar installation can perform ideally.The assembly on pitch-roofs works differently. A parallel cross assembly is our recommendation for pitch-roofs. The advantage for such an assembly is the ideal ventilation due to the bigger distance between roof and modules. Consequently the modules don’t heat up during summer time and are able to keep working efficiently.
The modules are either elevated or build on a tracking system. We offer not only both techniques to our investors and customers, we also show you with the help of an economic efficiency calculation which technique the most lucrative technique for your project is.
