These terms govern the participation of businesses ("companies", "you") on Solar Client (solarclient.de), operated by ⟨operator name — to be completed in Settings⟩ ("platform", "we"). They form the framework agreement between you and us; the membership packages you order are concluded under it. The service contracts you conclude with customers are separate contracts between you and the customer.
1. Eligibility and verification
1.1 Only businesses acting in the course of their trade (§ 14 BGB) may register as companies. Consumers cannot become companies. By registering you confirm that you act commercially and that the person registering is authorised to represent the business.
1.2 Admission requires verification: current commercial register extract or trade registration, proof of business liability insurance, VAT number (validated via VIES), and — for categories where the law requires it — the relevant licences or certificates (for example electrical qualification for grid connection work). We may request further documents, refuse admission without giving reasons, or withdraw it if documents expire, prove false or are not renewed.
1.3 You must keep all data and documents current. Expiring documents are flagged in your panel; an expired mandatory document automatically blocks quoting in the affected categories.
1.4 Team members you add act under your account and your responsibility. A person with an existing platform account is linked only after accepting our invitation e-mail. You alone decide which permissions each member has.
2. Nature of the platform; independence
2.1 The platform is an online marketplace under Regulation (EU) 2019/1150 (P2B Regulation) and the Digital Services Act. We forward customer requests to matching companies and provide tools (request pool, quoting, messaging, appointments, job tracking, contract text, invoicing of memberships).
2.2 You are an independent business. Nothing in this agreement creates an employment, agency, partnership, franchise or joint-venture relationship. You are not authorised to act or make statements on our behalf. We do not direct your work.
2.3 We do not verify, approve, supervise, accept or warrant your quotes or your work, and we are not a party to your contracts with customers.
3. Membership packages, prices and payment
3.1 Access to the request pool, quoting and messaging requires an active membership. Packages, durations, quote limits and prices are shown in your panel before ordering; prices are stated net and gross for your country. A trial package, where offered, is granted once per company.
3.2 An order is placed by selecting a package, accepting the membership contract shown to you and clicking "start payment". Payment is by bank transfer to the account shown, quoting the payment reference. The membership starts when we have confirmed receipt of payment (normally within 24 hours of your uploading the transfer receipt on working days) and runs for the period bought. It does not renew automatically; you order each period separately. Expiry warnings are sent 30, 14, 7, 3 and 1 day(s) before the end.
3.3 After expiry your account and profile remain; only quoting and sending messages stop until a new period is bought. Data is retained as described in the Privacy Policy.
3.4 As a business you have no statutory right of withdrawal. Once a period has started, fees are not refunded. If a platform outage attributable to us lasts more than 24 consecutive hours, your period is extended by the outage.
3.5 Invoices are issued electronically (PDF view and XRechnung/e-invoice XML) after payment confirmation and are available in your panel. For companies established in another EU member state with a valid VAT number the reverse-charge mechanism applies; otherwise German VAT is charged.
3.6 We may change package prices for future periods. Changes are announced at least 30 days in advance and never affect a period already paid.
4. Requests, quotes and contracts with customers
4.1 Requests are shown to you when your categories, asset types, service area, credentials and membership match (see the Privacy Policy, section 3.3, for the matching criteria). Before a customer accepts your quote you see the service details, photos, postcode and region and the customer's initials; you do not receive the customer's name, address, phone or e-mail.
4.2 A quote you submit is a binding offer for the validity period you state. It must be complete, truthful, priced in the customer's currency with VAT shown, and compliant with the law applicable to the customer (including consumer information duties where the customer is a consumer). You may withdraw a quote before acceptance.
4.3 On acceptance the platform generates the service contract text from the request and your quote and asks you to countersign. Appointments and job stages can be recorded only after both signatures. The customer's full contact details are released to you at acceptance.
4.4 You alone are responsible for your quotes, advice, performance, materials, timing, safety, permits, statutory warranties, invoices to the customer, taxes and compliance with technical rules (VDE, DIN, manufacturer instructions, local building and grid requirements). Disputes with the customer are settled between you and the customer.
4.5 You must not use the platform to obtain customer data and then offer, negotiate or perform the job outside the platform in order to avoid its rules; contact details are provided for the accepted job only.
4.6 You must record the true job stages and, on completion, mark the job completed so that the customer can review you.
5. Use of customer data (data protection)
5.1 From the moment contact details are released you are an independent controller under the GDPR for your own processing. You undertake to: use the data only for quoting and performing that job; not add customers to marketing lists or contact them for other purposes without their separate consent; keep the data confidential and secure; delete it when no longer needed for the job or a statutory retention period; and provide customers with your own privacy information where the law requires it.
5.2 Messages, appointments and job records on the platform are stored by us as described in our Privacy Policy and may be used by both parties as evidence.
5.3 Serious breaches of this section entitle us to suspend your account immediately and to inform the affected customers and, where required, the supervisory authority.
6. Company profile, content and conduct
6.1 You must keep your public profile accurate. Your legal name, address, register number and business e-mail are shown to logged-in users because Article 30 of the Digital Services Act requires traders to be identifiable. You decide the visibility of phone, mobile, team, certificates, portfolio and catalogue.
6.2 You may publish only content you are entitled to use and that is lawful, truthful and not misleading. Photos of persons require their consent. Reference photos must show your own work.
6.3 Prohibited: fake or duplicate accounts, misleading claims about qualifications or prices, discrimination, harassment, spam, manipulating reviews (own reviews, incentivised reviews, attacking competitors), scraping, interfering with the platform's security, and any unlawful activity.
6.4 You may reply once to each published review; the reply is subject to the same rules as the review.
7. Ranking and differentiated treatment (P2B Regulation, Art. 5 and 7)
7.1 In the request pool, requests are ordered by publication date (newest first). Requests from customers who registered with a marketing campaign code may be marked "featured" or "priority" and shown first for a limited time; the campaign is an advantage granted to the customer, not something a company can buy.
7.2 In the public company directory and on category pages companies are ordered by: match with the selected category and region, average rating and number of reviews, number of completed jobs on the platform, completeness of the profile, and — where a campaign benefit "featured profile" has been granted through a printed invitation campaign — a temporary featured position that is labelled as such. Distance to the searcher is used where a postcode is given. We do not sell ranking positions.
7.3 We do not operate our own solar business and do not compete with you on the platform. Companies with the same membership package receive the same features.
8. Suspension, restriction and termination (P2B Art. 4, DSA Art. 17, 23)
8.1 We may restrict or suspend your account, or remove content, if you breach these terms, if verification documents lapse or prove false, if payment is not received, if we receive credible reports of illegal content or conduct, or if we are legally required to do so. We give you a statement of reasons through the platform and by e-mail before or at the time of the restriction, unless the law prohibits it or immediate action is needed to prevent harm.
8.2 You may contest any such decision free of charge through our internal complaint-handling system within six months (see Appeals). We handle complaints diligently, in a timely and non-discriminatory manner, by a human reviewer, and we revoke a decision that proves unjustified.
8.3 Termination of this framework agreement by us for reasons other than a breach requires 30 days' notice with reasons. You may terminate at any time; a running membership period is not refunded. Statutory retention of contract, invoice and moderation records is unaffected.
8.4 Mediation: for disputes about this agreement that are not resolved through our complaint system, we are willing to engage with the following mediators (P2B Art. 12): the mediation bodies designated by the Federal Ministry for Economic Affairs, or another independent mediator agreed with you. Mediation is voluntary and does not affect the right to go to court. Because we are a small provider, the mandatory mediation duty of Art. 12 P2B may not apply, but we offer it regardless.
9. Availability, changes and our liability
9.1 We provide the platform with reasonable care and aim for high availability but do not guarantee uninterrupted or error-free operation. Planned maintenance is announced. Feature changes that affect your obligations are announced 30 days in advance (P2B Art. 3(2)); you may terminate before they take effect.
9.2 We are liable without limitation for intent and gross negligence, for injury to life, body or health, under the Product Liability Act and for guarantees we expressly gave. For simple negligence we are liable only for breach of cardinal obligations and limited to the foreseeable damage typical for this contract, and in any case limited to the total membership fees you paid in the twelve months before the event. Liability for lost profit, lost business and indirect damage is excluded to the extent permitted by law.
9.3 We are not liable for customers' statements, for the accuracy of request data, for a customer's creditworthiness, or for any damage arising from a job. You indemnify us against third-party claims arising from your quotes, work, content or breach of these terms, including reasonable legal costs.
10. Data of your business; confidentiality
We process your business and personal data as described in the Privacy Policy. Access to platform data (P2B Art. 9): you can see, in your panel, the requests matched with you, your quotes, messages, appointments, jobs, reviews, invoices and statistics. We do not share your quotes or messages with other companies. Aggregated, anonymised statistics (e.g. average quotes per request) may be published.
11. Term and changes
This agreement runs indefinitely. Changes are announced 30 days in advance by e-mail and in the panel; if you do not object before they take effect and continue to use the platform, they apply. You may terminate before the effective date.
12. Final provisions
12.1 German law applies, excluding the UN Sales Convention. Place of performance and exclusive place of jurisdiction for disputes with merchants is the registered seat of ⟨operator name — to be completed in Settings⟩.
12.2 Should a provision be invalid, the rest remains in force.
12.3 The English text is provided for convenience; the German version prevails for companies established in Germany.
