We will tell you why

Solar power from your roof is worth it



  • Low investment costs, purchase and installation costs are constantly falling.
  • Lucrative consumption of self-produced power, this eliminates the need to purchase expensive power from the grid.
  • Independent power supply thanks to battery storage systems. The self-produced power can be used at night and during bad weather.
  • Generate annual financial returns with a photovoltaic plant, making such a plant more attractive than other financial investments.
  • Feed-in tariffs, grants and tax breaks offer additional financial incentives.
  • Photovoltaic is the direct conversion of sun light into electricity. As soon as light hits the solar module, it produces DC power. The inverter of the PV plant converts this DC solar power into AC power. Unbeatable efficiency!
  • Self-produced PV power is environmentally friendly, sustainable and efficient. In this way, you make a contribution to the transition to clean energy and take your power supply into your own hands. Become an electricity producer yourself and produce 100% environmentally friendly solar power with your PV plant.
  • The best case is when the self-produced power is directly fed into the home power network and it consumed immediately. When there is a surplus, the self-produced power can be fed into the public power grid. However, the particular legal regulations of the country in regard to feed-in power have to be respected. When power is fed into the grid, the feed-in meter records the power yields from self-produced power. In Germany, for example, these yields are compensated at a fix priced for 20 years according to the government support program.
  • Another option is to store the energy in a battery. Battery storage allows the consumption of self-produced power to be optimized even more. This stored self-produced power is available for consumption also in the evening, free of charge. If the power demands exceed amount stored, power is then supplied from the public power grid.
  • Combining photovoltaic with the Solar-Log® and a heat pump offers another potential way to optimize the consumption of self-produced power. When there is a surplus, the power is supplied to the heat pump. With the combination of photovoltaic, Solar-Log® and EGO Smart Heaters, surplus PV power can be used to heat water, which can be used later when stored in combination storage tanks. The combination of combination with a heat and power generator (CHP) or a charging station also provides many advantages.
  • The aim is to consume the greater part of cheaper solar power directly in the building instead of purchasing expensive electricity from the grid.  This is how you can reduce your electricity bill from your utility company to a minimum. Photovoltaic is worth it! Self-consumption turns your investment into a sustainable energy supply and makes you independent of rising electricity prices.

    The sun offers 10,000 times more energy than we will ever need world-wide. Why should we not use this energy while saving money and making a contribution to environmental protection at the same time?

Good Reasons for an Intelligent

  • Solar-Log® Feed-in Management, implement individual and legal requirements in a practical way.
  • Solar-Log WEB Enerest™, keeping everything in sight and under control.
  • Solar-Log® protects your investment and provides banks and investors unmatched security.
  • Solar-Log®, a sound technology with innovative possibilities in the area of smart energy, the intelligent management of your energy consumption.

Solar-Log® immediately detects malfunctions

at photovoltaic plants

The system monitors the photovoltaic plant and triggers an alarm immediately when a malfunction occurs. The causes may vary greatly and lead high yield losses on the long-term. The failure of an inverter, the partial failure of a module or cable damage are just some examples of problems that are detected quickly at an early stage. Yield losses can be avoided with Solar-Log® to prevent any unpleasant surprises.

Solar-Log® can be upgraded at any time.

Plant completionAugust 2010

The inverters of this plant were not working for 20 days in June 2015, resulting in a complete failure with the plant producing no power during this time. This resulted in a loss of 195.29 € for the plant owner.

With a professional monitoring system like Solar-Log®, the failure can be detected immediately and fixed by the installer within about 5 days. The loss would have only been 48.80 €.


So that you can always keep everything in sight.

The new App for the Solar-Log WEB Enerest™ portal


The new App with its modern design and completely revised operating concept is available for smartphones and tables free of charge from the app store. It offers many new features and interactive graphics. For example, a single PV plant or several plants can be presented on a pinboard with customized views. Its interactive graphics can visualize current and historical plant data as well as data from connected accessories such as heat pumps and heating rods. The feed-in and self-consumption data can be concisely presented and compared. The News Center keeps users informed and up-to-date. All PV plants that are connected to the Solar-Log WEB Enerest™ portal via the Internet are supported. The data from these plants is automatically available in the App.
