Data Act solar cell data 2026 – inverters, data access and service replacement | Word/PDF/Excel

Do you own, rent or lease a connected solar PV system – but can only see the production values in the manufacturer's own app? The EU Data Act may give users the right to access actual product data and request that it be shared with an independent service technician or other authorised third party. With this practical package, you can request data, document a failure to respond or an inadequate response, and check an export before switching service partners.

For: individuals with a connected inverter, solar PV system owners, property managers, small businesses, housing cooperatives and solar PV service companies. The package covers data access and data sharing, not an agreement on electrical installation or direct technical connection.

Exactly which files are included?

Excel – nine tabs and eight control indicators

Overview, Systems, Data Fields, Request, Third Party, Delivery Test, Deviations, Actions and Read Me. The overview calculates explicitly registered cases, unclear application issues, missing metadata, pending or rejected requests, third party/GDPR issues, failed export tests and blocked/delayed actions. Formulas and status selections have been tested with synthetic cases and the customer version has been cleared.

Note: Zero warnings in an empty workbook does not mean that legal obligations are met. Excel cannot automatically retrieve data, connect to the inverter or decide a legal dispute.

Legal basis – EU Data Act 2026

General application: Regulation (EU) 2023/2854 (Data Act) began to apply substantially on 12 September 2025. The regulation applies, subject to its conditions, to connected products and associated services, including product data that can be retrieved from the actual product or its service.

Article 3.1 and Article 50: the requirement that new connected products be designed so that certain data is directly accessible applies to products and associated services that have been placed on the market after 12 September 2026. This is a different rule from the right under Article 4 to request access to already readily available data.

Article 4 – user access: when the user does not have direct access, the data holder shall make readily available product data and related service data, including relevant interpretative metadata, accessible without unreasonable delay, free of charge for the user, securely and in a structured, commonly used and machine-readable format. Requirements for continuous access and real-time apply only where relevant and technically possible. There is no general right to require the supplier to invent history that does not exist.

Article 5 – data to a third party: the user may request that an identified service partner be given access to such data. The data holder and recipient must consider rules on purpose, security, trade secrets and any applicable conditions between businesses. Do not share account passwords to bypass technical controls.

Article 7 – exceptions: special exceptions may apply when a connected product has been manufactured or designed by certain micro/small enterprises or, for a limited time, certain enterprises recently classified as medium-sized. These must be assessed before an unconditional right to data is claimed.

What is not automatically covered: proprietary forecasts, complex algorithmic analyses, the supplier's source code, history that has not been stored or all existing third-party APIs. The European Commission's explanation distinguishes between raw/pre-processed data and information created through more extensive analysis.

GDPR: if product data shows, for example, how and when people use a home or a system, an independent data protection assessment must be carried out before data is shared, especially if the user and the data subject are different persons. The Data Act does not replace the GDPR.

Practical workflow

1. Identify the product and check that it is indeed a connected inverter or associated service covered by the scope.
2. Verify the user's eligibility and identify the actual data holder.
3. Define which existing raw/pre-processed data points and metadata are needed for troubleshooting, comparison or service switch.
4. Fill in Word Template 02 for personal access or 03 for sharing with a selected third party.
5. Document receipt, the format delivered and any deficiencies.
6. Make a separate GDPR and security decision before forwarding the basis.
7. Test exported data with Template 05 and record only de-identified statuses and evidence references in Excel.

Frequently asked questions

Can I retrieve data from my old solar PV system?

It may be possible. Article 4 and Article 3.1 have different time rules, and the right only applies to data that is actually available within the scope of the regulation. Check the product's market date and specific data categories.

Do I have a right to all data in the manufacturer's app?

No. Raw and pre-processed product data and necessary metadata differ from proprietary forecasts, analyses and other derived information.

Can I choose a different service technician?

Article 5 may give the right to request that covered data be shared with a selected third party. It does not replace warranty conditions, electrical safety requirements or any special installation qualifications.

Do I have to pay to get my data?

The user's own access under Article 4.1 should generally be free of charge when the requirements are met. Terms and compensation between the data holder and third party are assessed separately.

Can Excel retrieve data directly from the inverter?

No. The workbook is a status and control register for requests, deliveries and deviations.

Are the PDF files digitally fillable?

No. The PDF files are searchable and printable. Edit the Word and Excel originals.

Are the work templates included in English?

The five work templates and Excel are in Swedish. An English user guide describes how the Swedish files are used.
