Yes. Creating a customer account is mandatory for placing orders in our online shop. As we supply exclusively to business customers, this process is required to verify your commercial activity.

Registration is reserved for business customers only. Please click on “Register” in the top-right corner and complete the form with your contact details. You will then be asked to upload your business documents so we can activate your account.

To verify your company with Solarcraft, we require your business registration document to be sent by email. For all other countries, a valid VAT identification number is required.

All prices are shown net, excluding statutory VAT and shipping costs. Many products include tiered pricing, meaning higher order quantities automatically result in lower unit prices.

Of course. You can reach our team by email at [email protected] or by phone at +49 721 909 990 99.

No. Solarcraft operates exclusively as a wholesaler for photovoltaic components and does not provide installation services.

All prices displayed in the shop already include any applicable cash discounts.

No, there is no minimum order value.

All technical datasheets, unit certificates and installation manuals are available directly on the respective product detail page under the “Downloads” tab. If any document is missing, please contact our sales team.

Yes. For larger construction projects, we offer project reservations. Please contact your dedicated sales representative with your bill of materials and the planned implementation period. Cart reservations without checkout are not technically possible.

Yes. Our shop is directly connected to our warehouse management system. The status “In stock” means the goods are physically available in Karlsruhe. For items marked “Incoming” or “On request”, we are happy to inform you about the expected delivery date.

We currently do not provide CSV exports of our product data. However, we can supply selected product information on request.

Compatibility should be verified using the technical datasheets (voltage, current, MPP range) of the module and the inverter. Many manufacturers also provide official compatibility lists.

If a product is discontinued (“End of Life”) during an ongoing project, we cannot guarantee that the same item will be supplied again. We will only offer technically equivalent alternatives.

Standard products generally do not have minimum order quantities. For larger projects or pallet-based orders, we are happy to review individual project pricing.

Stock items are usually ready for dispatch at short notice. After receipt of payment, shipping typically takes place within 24–48 hours, depending on the product and carrier transit times.

Yes. We can deliver directly to your end customer’s address. Please enter the deviating delivery address during checkout and mark it as a “construction site delivery”. Ensure truck access (up to 40 t) is possible for larger orders.

At present, we do not offer a neutral delivery note. Solarcraft will appear as the sender to your end customer.

Freight shipments are generally pre-advised by phone. Please make sure to provide a mobile number that can be reached during the day—ideally that of the site manager or installer—to avoid demurrage or failed delivery attempts.

Delivery is generally made “kerbside”. For pallet deliveries of modules, unloading equipment (forklift / wheel loader) must be provided on site unless otherwise agreed.

No, unfortunately this is not possible. You must place two separate orders.

Solar modules are shipped flat on special one-way or returnable pallets, professionally strapped and shrink-wrapped. Mounting rails (long items) are packaged separately.

The delivery address must be accessible for trucks. In most cases, unloading equipment (e.g. forklift) is required. Any deviations must be communicated in advance.

Transport damage or discrepancies must be noted upon delivery and reported promptly. We will then handle the clarification with the carrier.

As a business customer, you are obliged under § 377 of the German Commercial Code (HGB) to inspect the goods immediately upon receipt for completeness and transport damage. Any visible damage must be noted on the driver’s delivery document.

For technical defects (e.g. inverter malfunctions), please use the form in the dealer area. In many cases, direct processing via the manufacturer’s service department is faster. We will gladly assist with the necessary contact details.

Please report the defect with a photo of the nameplate, a description of the issue and measurement results (e.g. string voltage). After manufacturer approval, a replacement will be provided. Defective modules must be stored until the case is fully resolved.

As a wholesaler, we are liable within the scope of statutory warranty for defect-free goods. Costs beyond the replacement delivery are generally covered by manufacturer warranty allowances, provided these are stipulated in the warranty terms. We will assist you in submitting such claims.

As the statutory right of withdrawal applicable to consumers does not apply to B2B transactions, the return of non-defective goods is only possible on a goodwill basis.

If you receive an incorrect item, please notify us in writing within 48 hours, quoting the delivery note number. We will promptly arrange replacement delivery and/or collection of the incorrect goods.

Obvious defects must be reported immediately upon receipt of goods. Hidden defects must be reported without delay after discovery. Warranty periods are governed by the manufacturer’s specifications.

Typically, we require the invoice number, serial numbers, a fault description and meaningful photos.

As standard, we offer prepayment by bank transfer. For approved existing customers and partner companies, purchase on account (with a payment term) is also available following a successful credit check.

For environmental reasons, invoices are sent electronically by email to the billing address stored in your customer account. Copies can be requested at any time.

At present, it is not possible to add a custom reference or comment to your order.

Yes. If a valid VAT identification number and an EU delivery address are provided, the delivery is treated as a VAT-exempt intra-Community supply. VAT ID validity is checked automatically during registration.

For deliveries to Switzerland, invoices are issued net (without German VAT). Swiss customs duties and import VAT apply and must be paid by the recipient.

Your credit limit is determined based on your payment history and external credit assessments. For larger projects requiring a higher limit, please contact our accounting department or your sales representative in advance.

No. For accounting and tax reasons, each order is invoiced separately.

In the event of late payment, we reserve the right to suspend further deliveries, charge reminder fees and adjust the credit limit. Our B2B payment terms apply.

kWh (kilowatt-hour) is a unit of energy (power multiplied by time), while kWp (kilowatt-peak) indicates the nominal power of a module under Standard Test Conditions (STC). The annual ratio of kWh to kWp is referred to as the specific system yield.

AC stands for alternating current, while DC stands for direct current.

MPP stands for Maximum Power Point. It describes the operating point at which a solar module delivers maximum power. This point varies depending on irradiation, temperature and cell technology.

An off-grid system is a stand-alone system that is not connected to the public power grid. An on-grid system is a photovoltaic system connected to the public grid.

Load profiles describe the distribution of average electricity demand over the year at specific times of day (weekdays, Saturdays and Sundays).

Load management includes all technical measures aimed at consuming electricity when it is being produced by the PV system, thereby increasing self-consumption.

Smart grids are intelligent power networks that combine generation, storage and consumption. They use information and communication technologies to balance fluctuations and optimize energy flows.

A string refers to multiple solar modules connected in series.
