JUSTSOLAR — Solar Module Manufacturer

Leadership
The person you message is the person who decides.

Most of our competitors route B2B buyers through regional sales offices, country managers, and factory planners before a price commitment actually happens. We don't. Our flat structure exists because our customers told us it's the single biggest operational advantage we offer.

Frank Yang

Frank leads commercial strategy, production planning, and quality oversight at JUST SOLAR GROUP. Every proforma invoice that leaves the company is reviewed by him. Every warranty claim above a trivial threshold is signed off by him. Buyers routinely message him directly on WhatsApp with technical questions at hours most competitors' regional offices are closed.

The goal isn't that Frank personally negotiates every deal — it's that the structure guarantees buyers can always reach a decision-maker in one step. For a company shipping to 50+ countries with a 2 GW production line, maintaining that flat structure takes deliberate organizational discipline. It's the choice we've made because our B2B customer base tells us, repeatedly, it's what distinguishes working with us.

If you're working on a specific project — utility PPA, distributor stocking, OEM private-label, large C&I tender — the fastest way to get a useful answer is: send a structured RFQ or message directly on WhatsApp.

How we operate

Four organizational commitments that define our B2B relationship.

< 30 min
Avg WhatsApp reply

Flat structure, faster decisions

No regional-office stack between buyer and factory. Pricing, lead-time, and technical decisions happen in one conversation — typically within 30 minutes. Most Tier-1 brands route you through 3+ layers (regional rep → country manager → factory planner) before any commitment.

100%
PI review by Director

The Director signs POs personally

Every proforma invoice is reviewed by the Director before it goes out. No junior salesperson can commit on price or lead time unilaterally. This is both a quality gate and a signal to our buyers: you're talking to someone who can actually decide.

Stable
One contact, 25 years

Same point-of-contact from quote to warranty

Unlike large manufacturers where your sales rep changes when the deal closes (and again when you have a warranty claim), your direct channel at JUSTSOLAR is stable. Same WhatsApp thread from first quote to year-25 performance claim.

Honest
About our fit

Transparent on what we're not

We don't hide that we're outside the BNEF Tier-1 bankability list. For projects where Tier-1 wrap is mandatory, we structure sub-supplier arrangements honestly. We won't oversell — ask us what we can't do and you'll get a straight answer.

The wider team

We don't believe in inflating the org chart with vanity titles. Here's roughly how our 50+ employees are organized and what role each team plays in your order.

Quality Assurance

Incoming material inspection, in-line QC, EL testing, flash testing. Report directly to Director — cannot be over-ridden by commercial pressure on any module.

Logistics / Trade

Documentation, customs paperwork, freight booking, insurance handling. Tracks every container from factory to destination port.

Warranty & After-Sales

Technical review of claims, replacement-module coordination. Director signs off on every confirmed claim.

Macedonia Operations

Local team runs Skopje facility + EPC project delivery for EU customers. Direct reporting line to HQ.

Team member CVs, internal reporting lines, and equipment operator shift schedules available under NDA for utility-scale project due diligence.

Leadership FAQ

Who founded JUST SOLAR GROUP and who runs it today?
JUST SOLAR GROUP LIMITED was founded in 2011 in Shanghai as a vertically integrated solar energy solutions provider. Frank Yang is the Director and is the primary commercial and technical decision-maker. For buyer inquiries, factory audits, and warranty matters, Frank is directly reachable — no filter. Corporate structure: 50+ employees across our Jiaxing (China) headquarters, Skopje (Macedonia) facility, and SE Asia contract manufacturing partner.
Why do you emphasize 'direct to the Director' so much?
B2B solar purchasing has a structural problem: the person you talk to at most tier-1 brands doesn't have decision authority. They quote, you negotiate, they escalate, you wait, they come back with an answer 3 days later. Our flat structure removes that layer. When you ask 'can you match $0.12/W CIF Manzanillo with 30/70 BL terms?' the answer is yes/no in one reply, not three. For buyers with tight project timelines, this is the single biggest value we offer beyond price.
Is one person as the main commercial contact a risk if Frank is unavailable?
Fair concern. Continuity mitigation: (1) WhatsApp + email + office phone all monitored 7 days a week, with backup staff covering when Frank is in transit or on audit visits. (2) All quotes, orders, and commitments are recorded in our internal ERP — not stored only in one person's head. (3) For utility-scale orders (5 MW+), we can assign a dedicated project coordinator as secondary contact from the start. Ask for this during the RFQ process.
Do you have independent board members or investors?
JUST SOLAR GROUP LIMITED is a private company. We don't disclose capital structure publicly, but for utility-scale orders and bankability reviews we can share relevant financial statements, ownership structure, and banking references under NDA. For most distributor and C&I buyers, that level of disclosure is not needed — the published business license + ISO 9001 cert + reference customer list is sufficient.
What's your team's background?
Our core technical team has 10-20 years each in solar manufacturing, with backgrounds spanning module design, cell technology (TOPCon + HJT), QA engineering, and international logistics. Our production lines are operated by trained technicians working in rotating shifts, supervised by engineers. Specific CVs available under NDA for large-project DD. For ongoing engineering queries, our technical team is reachable via email with 24-hour response.
How does leadership handle warranty claims if they occur?
Director-level sign-off on every confirmed warranty claim. We don't delegate this to a claims department because (a) we don't have one — we're a manufacturing company, not an insurance business, (b) quick resolution of legitimate claims is our brand. Process: photo + SN + issue → 48-hour technical review → replacement modules shipped at our cost (typical resolution 4-8 weeks, or 1-2 weeks air freight if urgent). See /warranty for full claim process.
