(hereinafter "CheckSolar" or "Provider")
and the respective installation partner (hereinafter "Partner") who uses the CheckSolar platform to receive customer inquiries (leads).
(2) These GTC are directed exclusively at entrepreneurs within the meaning of § 14 BGB (German Civil Code). Use of the platform as a Partner requires the status of a business operator.
(3) Deviating, conflicting, or supplementary terms and conditions of the Partner shall only become part of the contract if the Provider has expressly agreed to their validity in writing.
(4) The version of these GTC valid at the time of the order or lead transmission shall apply.
§ 2 Description of Services
(1) CheckSolar operates an online platform through which end customers (hereinafter "Users") can submit inquiries for photovoltaic systems and related services.
(2) The Provider transmits qualified customer inquiries (hereinafter "Leads") to the Partner. A Lead contains the contact and project information provided by the User.
(3) The Provider is solely responsible for the transmission of Leads. A contract between the Partner and the User is neither guaranteed nor owed by the Provider. The conversion of a Lead into an order is the sole responsibility of the Partner.
(4) Leads are transmitted exclusively to the Partners selected by the User during the comparison process on the platform. No further distribution to additional Partners takes place.
§ 3 Registration and Partner Account
(1) Use of the platform as a Partner requires successful registration. The Partner is obligated to provide truthful and complete information during registration.
(2) The Partner is obligated to keep their access credentials confidential and to protect them from third-party access. The Provider must be informed immediately in case of suspected misuse.
(3) The Provider reserves the right to reject registrations without giving reasons or to suspend or terminate existing Partner accounts in case of violations of these GTC.
§ 4 Prices and Payment Terms
(1) Leads are billed at a fixed price per Lead. The applicable price will be communicated to the Partner before contract conclusion or upon registration and is accessible on the platform.
(2) All stated prices are exclusive of statutory value-added tax, where applicable.
(3) Billing occurs immediately upon transmission of a Lead. Payment is processed automatically through the payment service provider Stripe. The Partner agrees to the automatic charging of their stored payment method.
(4) The Partner is obligated to store a valid payment method with Stripe and to ensure its currency. In case of failed payment, the Provider reserves the right to suspend Lead transmission until outstanding amounts are settled.
(5) Invoices are provided to the Partner electronically via the platform or by email.
(6) The Provider reserves the right to adjust prices for future Leads with a notice period of at least 14 days. Price changes do not apply retroactively to already transmitted Leads.
§ 5 Lead Quality and Complaints
(1) The Provider endeavors to transmit qualified Leads. A Lead is considered qualified if it meets the following minimum requirements:
a) The contact details provided by the User are complete and correct. b) The User has expressed a comprehensible interest in a photovoltaic system or related service. c) The User is reachable at the provided contact details.
(2) The Partner has the right to file a complaint about a Lead within 14 calendar days after transmission (hereinafter "Complaint Period"). After expiration of this period, the Lead is considered accepted.
(3) A complaint is only possible in the following cases:
a) Not reachable: The User is not reachable despite at least three documented contact attempts on different days and through different channels (e.g., phone and email). b) Not qualified: The Lead contains obviously false or incomplete information (e.g., invalid phone number, fictitious address), or the User has no actual interest in a photovoltaic system.
(4) Complaints must be submitted in writing by email to info@check-solar.com, stating the Lead reference number and a comprehensible justification. The Partner must provide evidence of the circumstances of the complaint (e.g., documentation of contact attempts with date, time, and channel).
(5) The Provider reviews each complaint individually. The decision on the recognition of a complaint and any credit is at the sole discretion of the Provider. The Provider will process the complaint within 10 business days of receipt and inform the Partner of the result.
(6) In the case of a justified complaint, a credit in the amount of the price paid for the affected Lead will be issued. The credit will be offset against the next payment or refunded to the stored payment method. There is no entitlement to reimbursement beyond the Lead price.
(7) The following are specifically not grounds for complaint:
a) The User decides against entering into a contract with the Partner. b) The User has already accepted an offer from another provider. c) The Lead does not result in an order or contract conclusion. d) The Partner's economic expectations are not met.
§ 6 Partner Obligations
(1) The Partner commits to processing transmitted Leads promptly and professionally. Contact with the User should be made within 24 hours of Lead transmission.

§ 7 Data Protection
(1) The Provider processes personal data of the Partner in accordance with applicable data protection legislation, in particular the GDPR. Further details are governed by the Provider's Privacy Policy.

The Partner commits to processing this data exclusively for the agreed purpose and in compliance with the GDPR.
§ 8 Liability
(1) Otherwise, the Provider is only liable for breach of essential contractual obligations (cardinal obligations). In this case, liability is limited to the typical, foreseeable damage.

§ 9 Contract Duration and Termination
(1) The contract between the Provider and the Partner is concluded for an indefinite period.
(2) Either party may terminate the contract at any time with 14 days' notice to the end of the month, in writing or by email.
(3) The right to extraordinary termination for good cause remains unaffected. Good cause exists in particular if:
a) The Partner violates material provisions of these GTC. b) The Partner is in arrears with payments amounting to more than two Lead prices. c) Insolvency proceedings are opened against the Partner's assets or the opening is rejected for lack of assets.
(4) In the event of termination, already transmitted Leads and the resulting payment obligations remain unaffected.
§ 10 Confidentiality
(1) Both parties commit to keeping confidential information of the other party, which becomes known to them in the course of cooperation, secret and not to disclose it to third parties.
(2) This obligation does not apply to information that is publicly known without this being due to a violation of this agreement, or that must be disclosed due to legal requirements.
§ 11 Final Provisions
(1) The law of the Federal Republic of Germany applies, excluding the UN Convention on Contracts for the International Sale of Goods (CISG).
(2) The place of jurisdiction for all disputes arising from or in connection with this contract is Tallinn, Estonia, provided the Partner is a merchant, a legal entity under public law, or a special fund under public law.
(3) Should individual provisions of these GTC be or become invalid or unenforceable, the validity of the remaining provisions shall not be affected. In place of the invalid or unenforceable provision, the valid and enforceable provision whose effects most closely approximate the economic objective shall apply.
(4) Amendments and supplements to these GTC require written form. The Provider reserves the right to amend these GTC with a notice period of at least 14 days.
