Several clients asked me how to correctly input electricity generated on-site by e.g. a PV during the past week. I want to reshare this here as general guidance.
First, please note the software understands all inputs on the electricity consumption query page per year (i.e. they will be multiplied with the calculation period).
Second, there are two distinct cases, which require different handling.
If the demand is higher than the production on-site:
- Subtract the electricity generated on-site from the demand
- Input the result of this equation to the section called “Electricity consumption ”. This is the electricity that will need to be bought in addition to the generated electricity.
- Leave the exported energy field empty (everything produced is used on-site)
If the demand is lower than the production on-site:
- Leave the section called “Electricity consumption ” empty
- Subtract the electricity generated on-site from the demand
- Input the result of this equation to the section called “Exported energy”
I also recommend adding comments as they can help with documentation.
I hope this is helpful to some of you. You can find additional information here. If you have any further questions to this, please dont hesitate to post them here.
