ᐅ Limit the photovoltaic system to 70% capacity and install a remote control receiver for load management.

Hello,

Our photovoltaic system is planned to be installed on our roof, which will hopefully be ready, at the same time as the house construction in about 2 weeks.

We are currently a bit unsure about what makes more sense:

1. Limiting the system to 70% of its maximum capacity, or

2. Installing a remote control receiver that allows the utility company to control the system remotely.

How and why did you handle this with your photovoltaic systems?

We have an almost perfect south-facing orientation without shading, and our system will have a maximum output of 4.25 kWp.

Is it correct that if the utility company turns off the system, they still have to pay compensation?

Best regards,

Dirk

Hello Dirk,
I have point number 2 as a drawback: it costs an extra 400€ (euros)... My system has never been shut down in the 2 years of operation so far. Why? About 1 km (0.6 miles) away there is a solar park that gets shut down first in case of overproduction.
Yes, they pay some compensation (but you are responsible for figuring out when they shut down your system). You have to check a website every few months to see if you were affected.
The throttling is permanent - from when does the extra 400€ payment pay off? You will have to calculate that yourself.

Hello Wastl,

Thank you for your reply. I am currently leaning more towards solution 2 – the meter costs us EUR 249.00 including calibration plus VAT, so just under EUR 300.00.

Did you receive this website from the electricity provider, or from somewhere else?

Regards,

Dirk

Yes. The website was given to me in a letter from Bayernwerk. They are responsible for the power grid in our area and at the same time my clients.

@Wastl: Thank you!

We chose the 70% rule. This was a recommendation from the solar technician. The additional costs would not be worthwhile since the system usually does not operate at full capacity (in our case, the orientation is east/south/west on three roof sides) – only in summer, with perfect sunlight and optimal orientation. What does your solar technician say? They should have prepared the necessary calculations for sizing the photovoltaic system and be able to tell you when which power output can be expected.
