LTW Fragen und Antworten

frequently asked Questions

Every house roof is suitable for photovoltaic systems. Only some house roofs are “easier” to assemble than others. Our on-site experts will objectify the available roof areas and select the roof that can be built on most effectively. Of course, after the project planning, you will receive a full plan and a static report from us, as well as the expected effectiveness of the PV system.

A power storage system turns a PV system into a real power plant. Without storage, all of the electricity is sold into the grid and self-consumption is withdrawn from the grid. With an LTW storage system, you keep the electricity in your house and draw it from your LTW storage system if the PV system does not deliver. Without a network or electricity provider. All LTW storage systems also optimize all household loads and can thus save even more money for you through energy efficiency measures. If you want to become self-sufficient or just want to save money, LTW storage is the right technology for you.

With the right configuration, you won’t be selling a lot of electricity. However, the system itself decides after all the consumers in the house have been served and the battery is full to sell the electricity. With the energy you generate in summer, you also generate a buffer for a bad weather phase with fog in winter.

The more data you provide LTW for the calculation, the more precisely we can dimension your project. Our supervisors will advise you on site and go through all the necessary documents with you. For an initial estimate and a target price offer, we need an annual electricity bill, if possible a roof plan and the typical consumers that you use in the evening.

In short, YES. You too can benefit from the new technology and upgrade your old system.

LTW always plans for the longest possible service life of the storage system. Basically, we assume a service life of 15-30 years, depending on the use of the storage tank.
