Limit the photovoltaic system to 70% and install a wireless remote control receiver

Hello,

our photovoltaic system is supposed 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. To "limit" the system to 70% of the maximum capacity or

2. To install a radio ripple control receiver so that the electricity provider can remotely control the system.

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

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

Is it true that the electricity provider, if they shut down the system at some point, still has to pay compensation (in the form of a reimbursement)?

Best regards,

Dirk

Hello Dirk, I have number 2. Disadvantage: It costs an extra 400€ again,.... My system has never been shut down so far (2 years of operation). Why? About 1 km away there is a solar park that is shut down first in case of overproduction. Yes, they pay compensation (but you are obliged to find out yourself when they shut down your system). You have to check a website every few months and see if you were affected. The throttling is permanent - from when do the extra 400€ payment pay off? You have to calculate that yourself.

Hello Wastl,

Thank you for your reply. I am currently also leaning more towards solution 2 - the receiver costs us EUR 249.00 including calibration + VAT, so just under EUR 300.00.

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

Best regards,

Dirk

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

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

: Thank you!

We chose the 70% regulation. This was a recommendation from the solar installer. The additional costs would not be worth it, as the system does not deliver full power most of the time anyway (for us, N/E/S/W orientation on three roof sides) - only in summer with perfect irradiation and perfect orientation. What does your solar installer say? He has surely made the relevant calculations for the design of the photovoltaic system and should be able to tell you when which output will be delivered.
