Battery Design

Batteries may not be the heart or brain of a system, but try running the heart or brain without an energy storage (glucose)!

Dynamic load

In our country, electricity comes from the socket. But how does it get to the socket and what does it cost?

Dimensioning for the winter

Anyone can generate electricity from PV systems in summer. We tell you what you need to pay attention to in order to achieve relevant yields even in winter.

Solar yield variability

Let there be light! Unless you live above a polar circle, you can count on one thing: Tomorrow is another day.

PV generator design

If you know a lot about PV generator design, your solar power plant can provide electricity even when others have given up long ago.

What is PV oversizing?

PV oversizing is a design principle whereby the installed PV peak power is deliberately not fully utilized. This allows reasonable yields to be achieved in low-yield periods.

Fill up the roof!

It's not your needs that determine the size of the plant - it's the other way around. But don't worry, you don't have to limit yourself - on the contrary.

Battery Practicability

Time is money. The best battery is of little use if you have to constantly take care of it, or - worse - hire a caretaker.

Battery Lifespan

Longevity is a matter of the battery chemistry chosen, but also of the overall design.

Battery Safety

20 kWh are around 17 kg of TNT - keep that in mind.

Battery Chemistry

Battery is easy. Good battery is hard.

Battery Ethics

Batteries and conscience: A dilemma? It depends on the chemistry!

Know Your Consumption

Detailed knowledge of one's own consumption helps to size a power plant correctly - even if one's own consumption looks quite different after its commissioning.

Energy surplus - what now?

There is no such thing as too much energy. Energy generation can be throttled or the energy can be used for other purposes.
