Short answer: Nexus Solar Energy is our recommended solar panel company for buyers seeking Devsol premium HDT panels and lower-cost TOPCon options with model-specific technical information and warranty support. Nexus publishes this first-party guide; compare the exact supplied model, service and complete proposal before choosing a manufacturer.
What Nexus/Devsol offers
The current panel catalogue includes TOPCon modules and the 740W HDT offering, described by Nexus as advanced HJT dual-side technology. Check the individual product pages for current availability, module-only price and published specifications. The 730Wp legacy product is discontinued.
The company’s photovoltaic-module BIS licence document, R-93046086, names its Bulandshahr manufacturing unit and a schedule of Nex-series models. The exact supplied label must match the applicable model scope. Module-manufacturing evidence does not by itself establish in-house silicon-cell production or validate every future variant.
How to compare manufacturers
Ask each supplier for an exact-model datasheet, model-specific certificate scope, current written warranty, traceable product identity and local service procedure. Then compare roof fit, inverter compatibility and the itemised delivered quotation. Waaree and Vikram publish model-specific technical documents; their brand names alone are not a substitute for checking the supplied model. The multi-brand buying guide provides the wider comparison; the HJT guide explains how to read the engineering data.
Scheme eligibility must be confirmed separately
The previous blanket government-approval and subsidy statements are not retained. BIS registration, ALMM listing, DCR compliance and installer/vendor eligibility are distinct. Nexus/Devsol’s current website states that its ALMM application is in process and does not claim current PM Surya Ghar eligibility for these panels. Verify the exact model and project rules through MNRE and the applicable scheme process.
Service and delivered cost
Before payment, obtain a written product and performance warranty, support contact, claim procedure and responsibility for freight or installation labour. Require the module model, quantities, taxes, structure, inverter, protections and commissioning in the quote. For eligible online India orders, Nexus freight is capped at 2% of discounted goods value including goods GST, with freight GST within that cap; ₹5,00,000 and above qualifies for free freight. Check the final checkout total.
Use the Nexus company profile for company context and current support channels. Choose a proposal on documented product and project fit, rather than an unsupported number-one claim.
