Understanding your bill

2. Your contact details, customer number, plan information as well as our contact information for inquiries regarding your account or bill.
3. Your billing period and overview of your bill including the amount due and its due date. If you already set up a direct debit, the amount due will be automatically withdrawn from your account to update or change your payment details visit here.
4. Graphs give you an indication of your sonnenFlat parameters and your usage.
5. Minimum Annual Generation required: The minimum amount your solar system needs to produce to receive the full annual household usage allowance.
6. Annual Export Threshold: Energy exported above the annual export threshold will be paid at the solar feed-in rate.
7. Adjusted Annual Household Usage Allowance: Yearly energy credit for total household usage of energy from installed solar PV, sonnenBatterie, and the grid corrected for your actual generation. Once your (adjusted) annual usage allowance is exceeded, subsequent usage from the grid will be charged at the excess usage rate.
8. Your contract parameters.
9. Details of your sonnenFlat bill – broken down by Minimum Annual Generation, Export Threshold and adjusted Annual Household Usage Allowance.
10. Your generation: Shows your minimum annual generation vs. plan requirements. If your generation falls short, we will reduce the annual usage allowance pro-rata (adjusted annual household usage allowance).
11. Your electricity usage: Once your (adjusted) annual usage allowance is exceeded, subsequent usage from the grid will be charged at the excess usage rate. First, we look at the excess grid usage which has already been paid throughout your sonnenFlat year, then we apply the outstanding excess energy costs.
12. Your export: The credit for export applies as soon as you reached your export threshold. Every kWh fed into the grid above the threshold will be remunerated at the solar feed-in rate. Credits will be carried forward to future bills.
13. Your electricity supply details including information about your NMI, billing period and your next scheduled read date.
14. Find your meter read details here, including whether an actual or estimated read has been taken for your official meter data. This gives you a good overview of your grid usage, controlled usage and your export. This data is used for calculating your excess grid usage and remuneration for export.

Bill questions
Where can I find my FiT on the monthly bill?
The export graph on the monthly bill indicates when you will reach your Export Threshold. Credits for export are added to the annual bill only.
Why does my monthly bill indicate an estimated meter reading?
We must show grid meter readings on our customers’ bills that have been provided to us by your Local Distribution Network. These readings are sometimes ‘estimates’ but will always be corrected by actual readings within your sonnen anniversary.
What happens if I terminate my sonnenFlat contract?
If you terminate your sonnenFlat contract, you will not be charged an exit fee. You can leave at any time. Your contract parameters (i.e. Annual Household Usage Allowance, Annual Export Threshold and Minimum Annual Generation) will be adapted pro-rata according to the time you stayed with us.
Why do I have to pay for excess usage?
The Annual Household Usage Allowance is the credit for total household usage of energy from installed solar PV, sonnenBatterie, and the grid. Once your (adjusted) Annual Usage Allowance is exceeded, subsequent use from the grid will be charged at the excess usage rate.
