The Real Problem

Most Solar EPCs Run on
WhatsApp, Excel, and Hope.

01
Sales & Proposals

Your sales rep takes 3 hours to send one quote.

Your competitor's quote was in the client's inbox before you finished the second tab.

02
Project Execution

Stage 5 is "Installation." You have no idea who's on site.

You find out the project is delayed when the client calls. Not before.

03
Monitoring & Billing

Your 500kW Pune site underperformed for 11 days. You didn't know.

11 days of lost generation. No alert. Just a manually updated spreadsheet — and an angry client calling to ask why their bill hasn't reduced.

04
Finance & Payments

Your contractor payment trail lives in a WhatsApp thread.

No approval log. No UTR reference. No idea which milestone triggered which tranche. When the contractor disputes it, you have nothing.

05
Analytics & Reporting

You don't know which salesperson closed the most deals last quarter.

Revenue by project type, lead-to-closure rate, pipeline value, site generation trends — you're running a ₹5Cr business on gut feel instead of data.

Voltavic solves all five. Six modules. One platform. Built only for solar EPCs.

Geo-tagged photos at every stage
Engineers upload photos via mobile app. Each photo is auto-stamped with GPS coordinates, timestamp, and stage. Admin approves or rejects before the stage advances — no skipping.
3
Procurement request → delivery challan → inventory deducted
Raise multi-item purchase requests, get approval, generate delivery challan on dispatch. Every deduction is tied to a project, milestone, and person — immutable ledger.
4
Audit fails → milestones revert to RESUBMIT
If the quality audit rejects a stage, it reverts to RESUBMIT with the rejection reason logged. Commissioning milestone resets to PENDING. The trail is always complete.
5
Handover PDF auto-generated
All approved milestone photos, task completion records, and timestamps compiled into a branded completion report — ready for client sign-off.

What EPC Companies Say

Real words from people
building solar in India

★★★★★ 4.9 / 5 47 EPC companies across India MH  ·  GJ  ·  TN  ·  TS  ·  KA  ·  RJ
Quality Control
★★★★★

The milestone media verification changed everything. Every stage photo is GPS-stamped and goes through our QC lead before marking complete. We caught 3 installation issues in the first month — wrong earthing depth, loose DC connections, wrong panel angle.

We run 35 OPEX sites for textile factories. The inverter API sends the reading, Voltavic calculates the kWh, generates the GST invoice, and sends it to the client — without us touching anything. No billing team needed.

Frequently Asked Questions

Everything solar EPCs ask us before signing up

Real questions from operations heads, project managers, and directors at Indian solar EPC companies.

Yes, for residential leads. Upload the electricity bill — Voltavic extracts 19 fields, auto-sizes the system, builds the full BOM with GST, and generates a branded PDF. The only input you add is the client's name if it's not on the bill.
Yes. It works with MSEDCL, BESCOM, TANGEDCO, UPPCL, KSEB, BEST, Adani Electricity, Tata Power, BSES Rajdhani, BSES Yamuna, BRPL, BYPL, CESC, DHBVN, UHBVN, PSPCL, GETCO, and others — PDFs, scans, or photos. If a field can't be read, Voltavic flags it for manual entry rather than guessing.
Voltavic calculates panel count, cable runs, combiner boxes, MC4 connectors, earthing, and structure from system capacity + roof type. Every line item is fully editable after generation — change brands, quantities, or prices anytime.
Sungrow, Huawei, SMA, ABB, Delta, Growatt, Fronius, Solaredge, and Enphase via cloud APIs. Any brand with Modbus TCP or RS485 works via local gateway. Data polled every 5 minutes.
Yes — for full automation and push messaging, you need a Meta WhatsApp Business API account. Voltavic connects to it and manages everything from there: template configuration, message sending, delivery tracking, and follow-up rules — all from the Communications tab.
TRAI requires all commercial SMS to use a registered Entity ID, Sender ID, and pre-approved template — unregistered messages are silently blocked. Voltavic stores your DLT IDs per template and passes them automatically on every send. We include 48 ready-to-register templates covering every EPC stage.
Yes. Tasks, milestones, and photo capture all work offline. Data syncs when connectivity returns. GPS coordinates are stamped at capture time — not at sync — so location accuracy is preserved.
Set your tariff, billing cycle, and GST rate once at project setup. On each billing date, Voltavic reads actual kWh from the inverter API, generates a GST invoice, and sends it to the client — zero manual steps. If the inverter API is unavailable, you're alerted to enter readings manually.
Data is stored in an isolated schema per company on AWS Mumbai — not shared with any other customer. Role-based access limits what each user sees. Deactivating a team member invalidates their session immediately. Full data export available anytime.
Yes. Each warehouse is tracked separately. Stock deductions are tied to a specific location, project, and person. Low-stock alerts fire per warehouse. Transfers between locations create a ledger entry that updates both balances.
Yes. Every invoice shows CGST + SGST or IGST per line item, with HSN/SAC codes, your GST number, and client GST number for B2B. The invoice register exports as a date-range report ready for GSTR-1 filing.
Most teams are operational within one working day. A 90-minute live onboarding session (included in all plans) covers your branding, first proposal, team setup, and lead import. Field workers onboard by phone number — no email required.
You get a 7-day reminder before expiry. If you don't subscribe, the account goes read-only for 30 days — you can still export everything. After that, data is deleted with a final notice. If you subscribe, all your data carries over untouched.
Growth plan. CRM users and field workers are priced separately, so you don't pay full-user rates for technicians. Growth covers the complete EPC workflow — BOM sizing, monitoring, AI extraction, inventory, and auto-billing. Upgrade to Enterprise for dedicated support and custom integrations.
