Solar Power from Your Roof is Worth it

PV Plant Monitoring With Solar-Log™

  • 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.
  • Solar PV plants turn sunlight into usable electricity. When the sunlight hits the solar panels they produce DC power. The inverter then converts DC power into AC power (power used by your home or building). 
  • Solar power is a clean, sustainable and efficient way to produce power. Solar plant owners are helping to protect and preserve the environment and reduce their carbon footprint by producing environmentally friendly energy. Solar plant owners are also lowering their electricity costs by producing their own power instead of purchasing it from the grid.
  • Energy produced by your solar plant can first be directed towards your home or building’s usage, eliminating the need to purchase power from the grid when the plant is producing. Any power that is not used is then fed into the grid. In areas with net-metering, the utility’s meter actually runs backwards when power is being fed in. This means you are getting paid for any power your plant produces which you do not use. Some states or countries have feed in restrictions, meaning you can only feed in a certain amount of electricity or sometimes you are not allowed to feed electricity in at all. In these areas, smart home and energy management tools help make use of the excess power. 
  • 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.
  • One of the benefits of going solar includes using the greater part of cheaper solar power directly in the building instead of purchasing expensive electricity from the grid.  The use of self-produced power can reduce your electricity bill from your utility company. Solar 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?

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 App for the Solar-Log WEB Enerest™ portal*

The 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 components 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.
