From the sun directly to your smartphone: This is how you generate you

The solar boom is in full swing – especially for balcony power plants. While only 58 mini solar systems were newly commissioned in Germany in 2018, this number had already risen to over 274,000 by 2023 – and by 2024 it had reached 431,811 new balcony power plants.

This rapid development shows that more and more people want to generate their own energy – independently, sustainably and cost-effectively.

But with the growing number of balcony power plants, the need for transparency and control is also increasing. Many operators are asking themselves:

"How much electricity does my system actually produce – and how can I best use it?"

This is exactly where the MOE app comes in: It makes your electricity visible – live, understandable and directly on your smartphone.

In this blog post, we'll show you how to not only generate solar power, but also use it intelligently – for more efficiency, more control, and more independence.

What is a balcony power plant – and why is it worthwhile for you?

A balcony power plant – also called a mini solar system – usually consists of one or more solar panels and an inverter. The self-generated electricity is fed into your home's electrical grid via a special feed-in socket. The big advantage: You use directly what you produce – completely without bureaucratic hurdles.

The advantages at a glance:

Reduce electricity costs
Act in a climate-friendly manner
Quickly installed & no permits required
Flexible use – also in rented apartments
Information on obtaining permission from the landlord

But what many lack is a transparent insight into their own electricity flow.

Why electricity transparency is important

You generate electricity – but do you know, When and how much ? Without a direct overview, it often remains unclear:

how much electricity your balcony power plant actually produces
how much of it you use yourself
how much electricity you continue to draw from the grid
and most importantly, how much electricity you give away to your grid operator.

Many households are missing out on potential savings – simply because the data is lacking.

What can the MOE app do? – Your electricity data at a glance

With the MOE app, you have your energy flows in view at all times – live, easy to understand, and on the go. Whether it's electricity production, consumption, or weather conditions: the app brings together all relevant data and helps you use your balcony power plant even more efficiently.

Key features at a glance:

✔️ Live data in real time: See instantly how much electricity your system is currently producing – without complicated meter readings.

✔️ Trend analyses: Monitor your electricity generation over the course of a day, week, or month. Clear diagrams show you when your solar system is operating most efficiently.

✔️ Weather integration: Link your yield data with current weather conditions – for better consumption behavior.

✔️ Device overview: Easily manage multiple inverters or systems – ideal for households with extended PV infrastructure.

✔️ High compatibility: Currently optimized for Growatt, Shelly Smart Plug and evertech inverters – integration of Hoymiles is planned.

Why it's worth it – your advantages at a glance

Long-term evaluation	Track your efficiency over weeks and months

Example calculation: What benefits does the MOE app offer you?

A balcony power plant with 800 watts With proper alignment, the system generates approximately 800 kWh of electricity per year. The crucial factor is how much of that you... consume yourself.

Without an app – typical usage:

Self-consumption: approx. 35%
Example: 800 kWh × 35% = 280 kWh
Electricity price: €0.37/kWh
→ Savings per year: 280 × €0.37 = €103.60

Using the app – conscious use:

Self-consumption: realistically 48%
Example: 800 kWh × 48% = 384 kWh
→ Savings per year: 384 × €0.37 = €142.08

Thanks to the MOE app, you can adjust your electricity consumption in a targeted way and thus save noticeably more money per year – simply by using your solar energy more smartly.

Two everyday scenarios – this is how our customers use the app

1. Anna saves time with routine.
Anna now uses her dishwasher at midday instead of in the evening – because the app shows when her balcony solar power plant is generating the most electricity. The result: less grid power consumption, more savings.

2. Tom optimizes throughout the year
Tom regularly uses the MOE app to compare electricity production throughout the year. This allows him to see that his system operates particularly efficiently in spring – and to save additional electricity in winter through small adjustments, such as the use of LEDs.
