Solar Modules

Home solar panels have come a long way in recent years, and top-quality PV modules from emerce show just how much. In addition to being high-performance, you can also expect a reduction in CO² emissions with our modules. Able to withstand high wind and snow loads, all panels from us are TÜV proofed and have an extended warranty designed for maximum customer satisfaction. Our solar systems for home electricity are exactly what you need to create a more energy-efficient household.

Frequently asked questions

  • What is the difference between a solar module and solar panels?

    Solar modules consist of many PV cells that can be connected in series or parallel arrangements to generate the required direct current (DC). When assembling one or more solar modules as a field-installable unit, we are talking about solar panels.  

    There are various types of solar panels available in the market. Please visit the emerce online shop to compare and analyze the different types of solar panels and modules that we offer. 

  • How many solar cells are used in a solar module?

    Solar modules are a great way to generate electricity and meet your energy needs. One of the fundamental components of solar modules is solar cells. The two most commonly-used solar modules are 60-cell panels and 72-cell panels. Both these modules have their own sets of advantages and disadvantages.

    60-cell panels are preferred for residential use, and 72-cell panels are more commonly deployed for commercial use. The cost of installation for both these modules also varies to a great extent. emerce can help you in choosing the right solar module that meets your requirements. emerce ensures that you are able to find a product that is most appropriate according to the space available.

  • How many solar panels are needed to run a house?

    Using modern-day solar panels is a highly efficient way of meeting your electricity needs. This is because such panels allow you to generate enough power for your consumption without harming the environment. However, choosing the right type and number of panels for your home can be a complicated task. This is because many people are not aware of the actual amount of energy needed to power their house consistently. 

    Depending on the use of electricity, a normal household of up to four people has an average need of 3400 - 5500 kWh per year. If you are using electricity for heating and/or cooling it is higher than that. Modern PV panels today are producing more than 300 Watt. So, the number of panels can vary between 10 and 30 panels.  

  • How long do solar panels take to install?

    The time it takes to install solar panels varies depending on the size as well as location of the solar plant. For example, installing a 72-cell panel may take a bit more time than a 60-cell panel, especially if the space is limited. The layout of the roof also plays an important role in determining the time needed to install a solar system.  

    PV systems of an average family household can be installed in one day, including panels, mounting structures, inverter and cabling. Another half day would be needed when installing a battery storage solution as well as a few more hours for setting up monitoring solutions and establishing grid connection.  

    When installing a solar energy system for small factories, it could take up to six months. This timeframe could be caused by complex rooftop structures that require more detailed design planning as well as additional steps like getting needed permissions and conducting feasibility studies.
