Terms and Conditions
General Terms and Conditions of TST
1. General information, scope, contracting party
1.1 The following General Terms and Conditions (GTC) apply to all orders placed via our online shop by consumers and entrepreneurs (business customers).
1.2 A “consumer” is any natural person who enters into a legal transaction for purposes that predominantly cannot be attributed to that person’s commercial or self-employed professional activity. An “entrepreneur” is a natural or legal person or a legally capable partnership who, when entering into a legal transaction, acts in the course of their commercial or self-employed professional activity.
For entrepreneurs, the following applies: If the entrepreneur uses conflicting or supplementary general terms and conditions, their validity is hereby rejected; they shall only become part of the contract if we have expressly agreed to them.
Both consumers and entrepreneurs can be customers of TST SOLAR and are hereinafter referred to as the “Customer”.
1.3 In the event of a contract being concluded, the contract is concluded with the following company:
TST Solarstrom OHG
Baron Riederer-Str. 48
84337 Schönau
Tel.: +49-8726-910037
www.photovoltaik-shop.com
info@photovoltaik-shop.com
VAT ID: DE321868036
2. Ordering, conclusion of contract
2.1 Ordering in the online shop
The presentation of products in catalogues, in the online shop or on the TST SOLAR website does not constitute a binding offer for sale. Rather, it is a non-binding invitation for customers to submit a binding purchase offer (“Order”).
Ordering via the website takes place in the following steps:
1) Selection of the desired product(s).
2) Confirmation by clicking the “Add to cart” button.
3) Review of the selected product(s) in the shopping cart.
4) Clicking the “Proceed to checkout” button.
5) If applicable, selecting the standard VAT rate for businesses or customers not entitled to the zero VAT rate by ticking the relevant checkbox.
6) Entering customer details, in particular shipping and billing address, as well as a telephone number for delivery notification.
7) Final review and, if necessary, correction of the entered data and the ordered product(s) (type and quantity).
8) Binding submission of the order by clicking the “Place order with obligation to pay” button.
9) Before submitting the order, the customer may return to the page where the customer’s details are captured by using the “Back” function of the internet browser (or cancel the ordering process by closing the browser) in order to correct input errors.
10) The receipt of the customer’s order is confirmed immediately by email. This order confirmation does not constitute acceptance of the customer’s offer; a purchase contract is not concluded thereby.
11) We accept your offer within two working days by sending an order confirmation in a separate email, or by processing the payment transaction via our service provider or the selected payment service provider. The timing of payment processing depends on the selected payment method (see section “3. Payment methods”). The relevant alternative depends on which of the listed events occurs first.
2.2 Ordering via a sales representative / case handler
Ordering via a TST SOLAR sales representative takes place in the following steps:
1) Customer enquiry by email, contact form or telephone.
2) TST SOLAR sends the customer a non-binding quotation subject to change, and, if applicable, the questionnaire “Determination of VAT taxation for your order”.
3) The customer places the order by returning the completed and signed questionnaire “Determination of VAT taxation for your order” or informally by email or post.
4) TST SOLAR confirms the order by sending the corresponding order confirmation.
TST SOLAR reserves the right to reasonably adjust the delivery date between quotation and order confirmation if the duration of the ordering process—particularly the time until the customer places the order—requires this or if stock levels or product availability have changed in the meantime.
2.3 For orders placed via the online shop, TST SOLAR stores the contract text and sends it to the customer without undue delay by email together with the order data, these GTC and further information, e.g. on the statutory right of withdrawal for consumers. The GTC can also be viewed and saved at any time at https://www.photovoltaik-shop.com/en/terms-and-conditions . Previous orders can be viewed in the customer area of the online shop if the customer registered before placing the order and logged in with their customer account.
2.4 Obvious errors, typos or calculation mistakes in price information entitle us to contest the contract. Payments already received will be refunded promptly in such case.
3. Contract language
The language(s) available for the conclusion of the contract: German, English.
We store the contract text and send you the order data and our GTC in text form. You can view the contract text in your customer login.
4. Subject matter of the contract
4.1 Product description
We point out that the respective product description forms an essential part of the contract.
4.2 Product images
Without prejudice to your statutory warranty rights, we would like to draw your attention to the following. If you are unsure, please contact us:
Due to individual screen configurations (e.g. resolution and brightness), minor deviations between the displayed and actual product colours may occur.
4.3 Right of use
Any sketches, drafts, preliminary products etc. created by us for the fulfilment of the order may be legally protected. We grant you a simple, non-exclusive right to use them for the purpose of fulfilling the order within the contractually agreed scope.
5. Requirements and handling of customer content
5.1 Requirements
If it is necessary for the fulfilment of the order that you provide us with content (e.g. texts, data, files), the technical possibilities and any applicable requirements are governed by the respective product description.
You are solely responsible for the content, including its legality and accuracy. We do not perform editorial/content review prior to executing the order.
5.2 Compliance with applicable law
The content and the resulting products must always comply with the applicable legal provisions. In particular, they must not infringe any rights or claims of third parties (especially copyright, trademark or other proprietary rights) and must not contain or serve any content that glorifies violence, is discriminatory, racist, xenophobic, immoral or unconstitutional.
5.3 Indemnification
You indemnify us against third-party claims that may be asserted against us in connection with an infringement of their rights through our contractual use. You also bear the necessary costs of legal defence, including all court and attorney’s fees to the statutory amount. The indemnification does not apply if you are not responsible for the infringement. In the event of third-party claims, you are obliged to provide us without undue delay with all information necessary for the examination of the claims and for a defence, truthfully and in full.
5.4 Right of withdrawal from the contract
We reserve the right to reject the order or to withdraw from the contract if the content you provide violates legal or official prohibitions or common decency, or if there is a justified suspicion in this regard. This applies in particular to content that is unconstitutional, racist, xenophobic, discriminatory, insulting, harmful to minors and/or glorifies violence.
6. Delivery, self-collection, acceptance by the customer, transport damage
6.1 Delivery options and costs
Delivery is made to the delivery address specified by the customer via freight forwarder or parcel service. Deliveries are only possible to delivery addresses within the EU; deliveries outside the EU are only possible upon request. You can find the transport costs here: https://www.photovoltaik-shop.com/en/shipping/
6.2 Delivery requirements and place of delivery
The customer must ensure that the product can be properly delivered to the agreed place of delivery at the scheduled delivery time. For freight deliveries, the commissioned freight forwarding company usually contacts you to arrange a delivery appointment. For deliveries of large quantities, the delivery address must be accessible for articulated lorries, and suitable unloading equipment (e.g. forklift) as well as a person able to unload must be present. We will inform you in advance if delivery is to be carried out by an articulated lorry. Delivery of the goods is limited to transport and unloading at the first public kerb at the agreed delivery address. Delivery does not include delivery to specific premises, assembly and/or installation of the ordered goods unless expressly agreed otherwise. We do not deliver to islands or parcel stations unless agreed separately in advance.
6.3 Self-collection
You generally have the option to collect your order from TST Solarstrom OHG, Baron-Riederer-Str. 48, 84337 Schönau, Germany during the following business hours: Mon–Thu: 08:00–16:00 and Fri: 08:00–13:00. Collection must be announced at least one hour in advance. The shipping costs from the supplier/manufacturer to our warehouse in 84337 Schönau still apply.
6.4 Transport damage
For consumers:
If goods are delivered with obvious transport damage, please report this to the delivery agent immediately if possible.
1) Document the damage, ideally with photos
2) Have the delivery agent confirm the damage by signature on your copy of the delivery note
3) Contact us without undue delay, ideally with photos and—if available—serial numbers of the damaged goods
4) If the delivery agent refuses to confirm the damage, refuse acceptance of the delivery
Failing to report/notify has no consequences for your statutory rights and their enforcement, in particular your warranty rights. However, it helps us to assert our own claims against the carrier/transport insurer.
For entrepreneurs:
The risk of accidental loss and accidental deterioration passes to you as soon as we have handed the item over to the freight forwarder, carrier or other person or institution designated to carry out the shipment. For merchants, the inspection and notification obligations pursuant to § 377 of the German Commercial Code (HGB) apply. If you fail to give notice as required, the goods are deemed approved unless the defect was not recognisable upon inspection. This does not apply if we fraudulently concealed a defect.
Basic information on acceptance of goods can be found here: https://www.photovoltaik-shop.com/pub/media/tst/pdf/TST_Information_sheet_for_goods_delivery.pdf
7. Payment
The following means of payment are available in our shop:
7.1 Advance payment (bank transfer)
If you select advance payment in the online shop, we will provide our bank details in the order confirmation and deliver the goods after receipt of payment. You receive a 2% discount (skonto) on the value of the goods, but not on shipping costs. The discount amount is deducted automatically.
If you order based on a quotation via a sales representative and select advance payment by bank transfer, we will provide our bank details in the footer of the order confirmation and deliver after receipt of payment.
7.2 PayPal & PayPal Plus
To pay the invoice amount via PayPal (Europe) S.à r.l. et Cie, S.C.A., 22-24 Boulevard Royal, L-2449 Luxembourg (“PayPal”), you must be registered with PayPal, authenticate with your access data and confirm the payment instruction. The payment transaction is carried out by PayPal immediately after placing the order. Further information is provided during the ordering process.
With PayPal Plus, customers can also pay by direct debit or credit card—even without a PayPal account. However, we have no influence on whether these options are offered; additional payment options may be governed by your legal relationship with PayPal. More information can also be found here: PayPal Legal Hub (EN)
7.3 Amazon Pay
During the ordering process you will be redirected to Amazon’s website. To complete the ordering process via Amazon and to pay the invoice amount via Amazon Payments Europe S.C.A., 38 Avenue J.F. Kennedy, L-1855 Luxembourg (“Amazon”), you must be registered with Amazon, authenticate with your access data and confirm the payment instruction. The payment transaction is carried out by Amazon Pay within one banking business day after placing the order. Amazon Pay may offer additional payment options to registered Amazon Pay customers selected according to its own criteria. We have no influence on the offering of such options; additional payment modalities may be governed by your legal relationship with Amazon Pay. Further information can be found in your Amazon Pay account or here: https://pay.amazon.de/amazon-pay-nutzen
8. Right of withdrawal
Consumers have the statutory right of withdrawal as described in the withdrawal information. Entrepreneurs are not granted any voluntary right of withdrawal.
Our withdrawal information can be found at:
https://www.photovoltaik-shop.com/en/return
9. Retention of title
9.1 The product remains our property until full payment has been made.
9.2 For entrepreneurs, the following additionally applies: We retain title to the product until all claims arising from an ongoing business relationship have been settled in full. You may resell the goods subject to retention of title in the ordinary course of business; all claims arising from such resale are assigned to us in advance in the amount of the invoice value—irrespective of any combination or mixing of the retained goods with a new item—and we accept this assignment. You remain authorised to collect the claims; however, we may also collect the claims ourselves if you do not meet your payment obligations. At your request, we will release securities to the extent that the realisable value of the securities exceeds the value of outstanding claims by more than 10%.
10. Prices
10.1 The stated prices include German VAT at the statutory rate and other price components. For eligible photovoltaic components under the Annual Tax Act 2022 (§ 12 para. 3 nos. 1–4 of the German VAT Act, as referenced), prices are stated with 0% VAT. If the customer and/or certain products are not eligible for the zero VAT rate, the applicable VAT of the delivery country will be charged additionally. Shipping costs may apply. The VAT rate on shipping costs corresponds to the VAT rate of the items in the customer’s order. Prices for resellers and installers in the restricted area (after approval by TST SOLAR) are generally net prices plus current VAT less any discounts. Further information: https://www.photovoltaik-shop.com/en/sales-tax-regulations
Delivery of an order at the zero VAT rate is only made if the statutory conditions allow. In order to be able to prove the customer’s eligibility to apply the zero VAT rate—especially to tax authorities—TST SOLAR may require a self-declaration regarding the customer’s VAT status. If, after placing and paying the order, we require further information or documents in accordance with statutory requirements, we will inform you by email. TST SOLAR also reserves the right to take legal action in the event of a demonstrably false self-declaration in order to claim VAT retrospectively. If there is sufficient suspicion of a false self-declaration, TST SOLAR may refuse application of the zero VAT rate or reject the customer’s order.
10.2 If agreed in the contract, TST SOLAR is entitled to request an advance payment of the total remuneration.
10.3 Unless otherwise agreed, all invoices issued by TST SOLAR are due and payable within 7 calendar days of receipt.
11. Use and registration
11.1 Use of the TST SOLAR websites including ordering is largely possible without registration. However, registration allows you to process future orders faster and more conveniently. Registration is free of charge and only possible subject to these GTC.
11.2 Registration is completed by creating a user account and agreeing to these GTC. Upon final activation of registration, a contract for the use of this website (“User Agreement”) is concluded between TST SOLAR and the Customer. This User Agreement is independent and must be distinguished from contracts or legal relationships arising from orders placed.
11.3 TST SOLAR reserves the right to reject registration without stating reasons. There is no entitlement to conclude a User Agreement. Final activation may take up to seven (7) working days. Shortly after registration, an automated preliminary activation may occur; this does not create any entitlement to final activation or continued use of individual services. TST SOLAR reserves the right to terminate the preliminary activation at any time without stating reasons.
11.4 Only one user account per customer is permitted. Creating or maintaining multiple user accounts—especially re-registering after termination or blocking of an account—is expressly prohibited and constitutes, in each case, an extraordinary reason for termination of the User Agreement. Use of one account by multiple persons is not permitted. User accounts are not transferable.
11.5 To create a user account, the customer must register with their full first and last name, address and a valid email address.
11.6 The data requested during registration that is required must be provided completely and accurately. Providing false data constitutes an extraordinary reason for termination. Any subsequent changes must be corrected by the customer independently and without undue delay.
11.7 Customers must keep their password confidential and must not pass it on to third parties. Customers are responsible for adequately securing their access and password. Customers are generally liable within the scope of their duty of care for all activities carried out using their user account.
11.8 The User Agreement may be terminated by ordinary and/or extraordinary termination. The examples of extraordinary termination reasons in this section are not exhaustive. Termination of the User Agreement does not affect orders already placed. The agreement for website use and legal relationships arising from orders are distinct and must be distinguished from one another.
11.9 The user may terminate the User Agreement at any time without stating reasons.
11.10 TST SOLAR may terminate the User Agreement at any time with two weeks’ notice. Rights to block services (in whole or in part), withdraw write permissions, and the right of extraordinary termination remain unaffected.
12. Warranty
12.1 Statutory warranty rights apply to all goods from our online shop.
12.2 Consumer claims for defects are governed by statutory provisions within statutory limitation periods unless otherwise stated below.
12.3 For entrepreneurs, the warranty period is 1 year from delivery. For used items, the warranty period is also 1 year from delivery if the customer is a consumer. § 438 para. 1 no. 2 BGB remains unaffected. For delivery of used items to entrepreneurs, claims for defects are generally excluded.
12.4 For entrepreneurs, TST SOLAR will initially remedy defects at TST SOLAR’s discretion by repair or replacement.
12.5 Entrepreneurs must notify TST SOLAR of obvious defects within two weeks of receipt; timely dispatch of the notice is sufficient to meet the deadline. Otherwise, warranty claims are excluded. For merchants, § 377 HGB applies.
12.6 For entrepreneurs, only the product description by TST SOLAR is deemed agreed as the quality of the goods. Public statements, promotions or advertising by the manufacturer do not constitute contractual quality.
12.7 If an entrepreneur claims reimbursement of expenses pursuant to § 478 para. 2 BGB, this is limited to max. 2% of the original value of the goods.
12.8 The one-year warranty period and the liability/warranty limitations do not apply in cases of intent or gross negligence on the part of TST SOLAR, in the event of personal injury attributable to TST SOLAR, in cases of fraudulent concealment, or in the case of supplier recourse pursuant to §§ 478, 479 BGB. Liability under the Product Liability Act remains unaffected.
12.9 Without prejudice to statutory warranty rights, we point out that minor colour deviations may occur due to individual screen configurations (e.g. resolution and brightness).
12.10 In warranty cases, please contact: TST Solarstrom OHG, Baron-Riederer-Str. 48, 84337 Schönau; Tel. +49-8726-910037.
13. Guarantee
13.1 Product descriptions do not constitute guarantees.
13.2 Within product descriptions, TST SOLAR may refer to manufacturer guarantees, which do not bind TST SOLAR. As a rule, TST SOLAR does not grant guarantees unless expressly agreed in a separate guarantee declaration. TST SOLAR is happy to assist customers in asserting manufacturer guarantees against the manufacturer.
13.3 If TST SOLAR grants a guarantee beyond statutory rights, the customer may—unless otherwise promised—only claim repair under the guarantee, not withdrawal, price reduction or damages. No entitlement arises to free replacement with new goods or replacement equipment during repair.
13.4 The guarantee period begins upon delivery and is not interrupted or suspended by repair. Statutory warranty claims remain unaffected.
13.5 In guarantee cases, please contact: TST Solarstrom OHG, Baron-Riederer-Str. 48, 84337 Schönau; Tel. +49-8726-910037, email: info@photovoltaik-shop.com
14. Liability
We are liable without limitation for claims based on damages caused by us, our legal representatives or vicarious agents
1) in the event of injury to life, body or health,
2) in the event of wilful intent or gross negligence,
3) for guarantee promises, if agreed, or
4) to the extent that the scope of application of the Product Liability Act is opened.
In the event of a breach of material contractual obligations (cardinal obligations) through slight negligence by us, our legal representatives or vicarious agents, liability is limited to the foreseeable damage typical for the contract.
Otherwise, claims for damages are excluded.
15. Processing of personal data
TST SOLAR processes personal data relating to the customer. The processing of personal data is governed by the privacy policy, which can be found here: https://www.photovoltaik-shop.com/en/data-protection
16. Notes on the return of batteries pursuant to § 18 BattG (German Battery Act)
Pursuant to § 18 BattG, we as a retailer are obliged to inform you as follows:
16.1 Consumers are legally obliged to return used batteries and solar storage units. Batteries must not be disposed of with household waste. We are obliged to accept used batteries free of charge. After use, consumers can return/send batteries to our company address.
16.2 Reimbursement of return shipping costs is not possible. End users can usually return batteries in household quantities to collection points established by public waste management authorities (e.g. municipal recycling centres). Batteries/accumulators containing hazardous substances are marked with the symbol of a crossed-out wheeled bin. This means the battery must not be disposed of with household waste. Near the symbol you will find the chemical designation of the hazardous substance with the following meaning:
"Cd": the battery contains more than 0.002% cadmium by mass;
"Pb": the battery contains more than 0.004% lead by mass;
"Hg": the battery contains more than 0.0005% mercury by mass.
17. Notes pursuant to the ElektroG (German Electrical and Electronic Equipment Act)
As of 24 July 2016, the new provisions of the Electrical and Electronic Equipment Act (ElektroG) apply. This results in new obligations for manufacturers, distributors and customers.
17.1 Obligation of separate disposal of old devices / separation of batteries and accumulators. Owners of old devices must ensure separate collection apart from unsorted municipal waste. Electrical and electronic equipment must therefore not be disposed of with household waste. ElektroG requires that all such devices are permanently labelled with the following symbol:
The symbol depicts a crossed-out wheeled bin and indicates the separate disposal of electrical and electronic waste equipment.
17.2 Obligation to separate batteries and accumulators. Customers must separate used batteries and used accumulators that are not enclosed by the old device before handing it in at a collection point.
17.3 Return option. TST SOLAR is obliged to take back old devices in accordance with ElektroG.
The following devices are taken back: old devices with an edge length of up to 25 cm without the purchase of a new product; larger old devices if you purchase a device of the same type from us (same type, essentially fulfilling the same functions as the new device). After use, consumers can return/send such devices to our company address.
Return is free of charge. (A fee may only be charged if your electronic waste device is not subject to the take-back obligation under ElektroG.) If, due to contamination, the old device poses a risk to human health and safety, acceptance may be refused. This generally does not apply to damaged old devices. You can also return electrical devices to collection points established by public waste management authorities (e.g. municipal recycling centres).
17.4 Responsibility for deletion of personal data. You are responsible for deleting any personal data that may still be stored on your old device.
18. Technical advice
Any application-related technical advice provided by TST SOLAR verbally, in writing or by tests—outside a separate consulting agreement (fee-based consulting contract)—is provided to the best of our knowledge, but only as non-binding information, also with regard to any third-party rights, and does not relieve the customer of their own obligation to check the suitability of products supplied by TST SOLAR for the intended procedures and purposes. Application, use and processing of products are outside TST SOLAR’s control and are the sole responsibility of the customer or persons commissioned by the customer.
19. Dispute resolution
We are willing to participate in an out-of-court dispute resolution procedure before a consumer arbitration board. The competent body is the Federal Universal Conciliation Body at Zentrum für Schlichtung e.V., Straßburger Straße 8, 77694 Kehl am Rhein, Germany, https://www.universalschlichtungsstelle.de/.
20. Final provisions
20.1 If you are an entrepreneur, German law applies to the exclusion of the UN Convention on Contracts for the International Sale of Goods (CISG).
20.2 If you are a merchant within the meaning of the German Commercial Code, a legal entity under public law or a special fund under public law, the exclusive place of jurisdiction for all disputes arising from contractual relationships between us and you is our registered office.
20.3 If individual clauses of these GTC are wholly or partly invalid, the remainder of the contract remains valid. To the extent clauses are invalid, the content of the contract is governed by statutory provisions.
