These Terms of Use govern the BestSolar websites, applications, online resources and business communication services that reference them (the “Services”). The provider is Best Energy Technology Co., Ltd., a company incorporated in Hong Kong SAR, unless a separate agreement identifies another entity. “You” means the individual using the Services or the organization that individual is authorized to represent.
1. Scope and acceptance
The Services include product information, technical resources, inquiries, accounts, monitoring, warranty and support, and related email, WhatsApp, SMS, telephone and AI-assisted functions. Availability depends on the product, region, account and service offered.
By using Services subject to these terms, you agree to the terms applicable to that use. You must have authority to act for an organization and to use any restricted account or feature. Additional terms are presented before use where a feature requires them.
A separately agreed purchase, supply, distribution, installation, service or software license agreement takes precedence for matters it governs. These terms do not replace product warranties, mandatory consumer rights or expressly agreed commitments.
Acceptance does not constitute consent to optional analytics, advertising, marketing or recording. Required permissions are obtained separately.
2. Permitted use and accounts
You may use the Services for lawful evaluation, purchase, installation, administration, operation and support of BestSolar products, personally or for an authorized organization. This permission does not authorize resale of the Services, unauthorized copying or access to another customer’s information.
Keep account and contact information accurate, protect authentication methods, use only assigned permissions, and notify us promptly of suspected unauthorized access. You are responsible for activity you authorize and reasonable account safeguards; this does not excuse our own obligations.
An employer, installer or other organization administering an account or system may control access and configuration under its policies and agreement. Permission to view information does not necessarily authorize a transaction, product change or disclosure.
3. Product information, content and documentation
General website descriptions, examples, chats and AI responses support evaluation and do not replace current product documentation, agreed specifications or advice from qualified professionals. Use instructions appropriate to your product model, firmware, installation and jurisdiction. Electrical, battery and energy-storage work must follow applicable safety instructions and local requirements and be performed by appropriately qualified people.
We may correct errors and update information. A displayed product, indicative price or feature does not itself guarantee availability or create a binding offer. Commercial commitments arise through the applicable transaction or authorized agreement.
Rights in our materials, branding, designs, software and documentation belong to BestSolar or the relevant owners. Except as permitted here, by a separate license or by law, you may not reproduce, redistribute, sell or exploit them.
You may download documentation and share necessary copies with authorized colleagues, customers or qualified contractors for legitimate evaluation, installation, operation, maintenance and support. Keep ownership notices and the document’s integrity. This permission does not authorize unrelated public republication, presenting modified material as official, copying website design or implying endorsement through our branding.
Software, firmware and applications may have separate licenses. Applicable open-source licenses and mandatory rights concerning interoperability, repair or other protected activity continue to apply.
4. Privacy and individual choices
Our Privacy Statement explains data categories, purposes, Google and Meta analytics and advertising, cloud and communications providers, international processing, AI, retention and rights. Its data restrictions apply alongside these terms; a submission license does not override them.
Use Cookies in the website footer to manage optional Analytics and Advertising. Marketing subscriptions and recording permissions are managed separately. Optional advertising is not required for ordinary inquiries or essential website functions.
You may change multiple preferences by contacting legal@bestsolar-group.com and explaining your request. Withdrawal of one choice does not automatically change every other choice; we apply the scope you specify and applicable law.
5. Business messaging and telephone services
Calls and messages may be routed or transferred to authorized personnel, and outbound calls may display a shared BestSolar number. Availability, delivery and quality depend on carriers, platforms, devices and connectivity. Messages can be delayed or fail to arrive. Delivery or read indicators do not establish acceptance of an order or contractual commitment.
Our browser and application calling feature is a business communications service and does not provide emergency calling. Maintain another suitable means of contacting emergency responders. Features requiring microphone or other device permissions need those permissions to operate.
We obtain the permission required by law and platform rules before initiating messages. A response to your inquiry allows us to handle that conversation; it does not automatically create an ongoing marketing subscription. Where an unsolicited introductory business message is lawful, we send only one message concerning that outreach through the channel unless you respond. This rule does not create an exception to an opt-in requirement. Service, safety, warranty and legally required communications follow their own purposes.
WhatsApp Business. Our channel handles the business and service interactions described to you. An approved template does not replace recipient permission. Ask us to stop in the conversation or through our contact address. Your WhatsApp account remains subject to the applicable WhatsApp Terms. Processing by Meta and the providers supporting delivery is explained in the Privacy Statement.
SMS program
BestSolar, operated by Best Energy Technology Co., Ltd., sends SMS through Twilio and relevant carriers. Messages may concern requested inquiries, sales or order coordination, service updates and support. Promotional messages are sent only if included in the subscription you validly authorize. The sign-up or permission notice identifies the applicable program and message categories before you join.
- Permission: Subscribe only a number you are authorized to use. Marketing consent is not a condition of purchase. Permission for one program does not authorize unrelated messages or another business. Tell us if you give up or change your number.
- Frequency and charges: Message frequency varies with your requests, transactions and subscriptions, as explained in the applicable sign-up notice. Message and data rates may apply under your carrier plan.
- Stop: Reply STOP to unsubscribe, use another supported standard opt-out method, or contact us. We may send one final confirmation, then stop SMS to that number unless you validly subscribe again. Unsubscribing does not cancel an order or warranty; necessary contact can use another lawful channel.
- Help: Reply HELP or email legal@bestsolar-group.com.
- Delivery: Timing and successful delivery are not guaranteed. To the extent permitted by law, carriers are not responsible for delayed or undelivered messages. Mandatory responsibilities remain unaffected.
- Changes: Before materially changing a program’s subject, frequency or data use, we provide notice and obtain any fresh permission required. We may suspend or end a program subject to applicable obligations.
We do not sell or share mobile information with third parties or affiliates for their marketing or promotional purposes. Text messaging originator opt-in data and consent are excluded from general sharing provisions and are not shared for another party’s own use. Providers may process them solely as necessary to operate and deliver our messaging service. SMS subscription and consent records are excluded from advertising audiences and customer matching. The Privacy Statement provides the retention and rights rules.
6. Recording and transcription
Calls covered by the applicable recording notice are recorded and transcribed for the purposes explained before recording. We obtain any agreement required by law. If you decline, tell the representative or use a suitable written channel. Do not record another participant unlawfully.
The Privacy Statement explains access, retention, deletion and your rights for recordings and transcripts. Recording permission does not authorize unrelated uses of the content.
7. Artificial intelligence
AI may assist with public articles, descriptions, images, translations and other materials across our websites. We review material as appropriate and provide specific notices or markings where required. AI-assisted content can contain errors and is provided for general information.
Customer service AI may answer questions, translate messages and produce transcripts. We identify direct interaction with an AI assistant and explain how to reach a person. Staff may use disclosed translation and transcription features while handling a request.
AI responses and transcripts can be inaccurate, incomplete or out of date. They do not by themselves create an offer, change a contract, grant warranty coverage, approve a safety-critical configuration or bind BestSolar to a price or service commitment. Obtain confirmation from authorized personnel where needed. Applicable legal obligations and actual authorized commitments remain effective.
You must have authority to provide your inputs. Do not submit unlawful material or another person’s information without authority, evade protections, seek unauthorized access, or overload the Services. Highly sensitive information should only be provided where the relevant service requests it through an appropriate process.
We do not use customer communications, recordings, transcripts or customer service AI inputs and outputs to train, retrain or fine-tune AI models, and we do not authorize providers processing that content for us to use it for their own model training or improvement. The Privacy Statement governs related processing and retention.
8. Material you submit
You retain your rights in submitted information and material. You grant us a limited, non-exclusive permission to receive, store, reproduce, transmit, translate, transcribe and otherwise process it as reasonably necessary to provide the requested service, handle the transaction or support interaction, protect the service and meet legal duties. Necessary providers may act for us within the same purpose and restrictions.
This permission does not authorize public display of private customer information, unrelated promotion, advertising customer matching or AI model training. Those activities remain subject to the relevant specific notice, permission and prohibition. We obtain separate authorization for a public case study, testimonial or promotional use of a private submission.
You must have the necessary rights and authority to supply material. We may restrict unlawful or harmful submissions and need not publish unsolicited suggestions. Personal data retention follows the Privacy Statement; this license does not create an indefinite retention right.
9. Prohibited conduct and service availability
Do not use the Services to gain unauthorized access, distribute malware, disrupt availability, send unlawful or unauthorized marketing, harass others, impersonate a person, manipulate caller identity deceptively, or infringe intellectual property, confidentiality or privacy rights. Do not interfere with product firmware, monitoring data or safety controls in a way that endangers people, property or operation. Follow applicable trade, safety and other legal requirements.
We may investigate misuse, maintain or change features, and proportionately restrict access where necessary for security, law, misuse or the end of a relevant account relationship. We provide notice where practicable and required. These rights do not override an agreed warranty, service commitment, mandatory consumer right or applicable data-access obligation.
Except for an express commitment or legal requirement, we do not promise that every online or communications feature will always be available, uninterrupted or error free.
10. Responsibility and third-party services
To the extent law permits, we exclude implied warranties concerning general online Services, including merchantability, fitness for a particular purpose and non-infringement, where these have not been expressly agreed. Product warranties and separately agreed service commitments continue on their own terms.
To the extent law permits, BestSolar and its suppliers are not responsible for indirect or consequential loss, including loss of profit, business opportunity or use, arising from access to or inability to use general online Services. Responsibility for a purchased product or contracted service remains governed by its agreement and applicable law.
These exclusions do not apply where unlawful, including liability for fraud, injury or other matters that cannot lawfully be excluded. They do not remove mandatory consumer or privacy rights or excuse an express obligation that law requires us to honor.
Independent platforms and linked websites may have their own terms and privacy notices. A link does not imply endorsement of everything its operator does. We do not control independent websites or every carrier or platform action; this does not remove responsibilities we have for selecting and instructing our providers.
11. Governing law and disputes
For matters governed by a purchase, supply, distribution, installation, EPC or other service agreement, that agreement’s counterparty, law, forum and liability provisions take precedence.
For matters governed only by these Terms of Use, the following rules apply, subject to mandatory local rights. Location means your habitual residence or the principal place of business of the organization using the Services.
| Location | Applicable law and forum |
|---|---|
| EEA, United Kingdom or Switzerland | The law and courts of the relevant country of habitual residence or principal place of business. |
| United States or Canada | Hong Kong SAR law, preserving mandatory state or provincial consumer rights; Hong Kong SAR courts or local courts where mandatory law gives that right. |
| Mainland China | The law of the People’s Republic of China and the competent people’s court for the place of performance. |
| Other locations | Hong Kong SAR law without its conflict rules, with non-exclusive jurisdiction in Hong Kong SAR courts. |
You retain access to any court, regulator, complaint process or remedy available under mandatory law. The United Nations Convention on Contracts for the International Sale of Goods does not govern these general online-service terms.
12. Changes and contact
We identify the published version and provide reasonable notice of material changes, with additional acceptance where required. Changes apply prospectively and do not remove accrued rights. Continuing use after a validly notified change has the effect allowed by applicable law; it does not supply separate data or marketing consent.
If a provision is unenforceable, it applies only to the lawful extent and the remaining terms continue where they can operate independently. Delay in enforcing a right does not by itself waive it. Interpretation of translations follows applicable law and any separate agreement without removing mandatory local protections.
For questions about these terms, SMS assistance or service preferences, contact Best Energy Technology Co., Ltd. at legal@bestsolar-group.com. Privacy requests follow the Privacy Statement. The current Terms of Use are available on our website.
