Nexus Solar Energy and Devsol exhibited at REV Expo Uttar Pradesh 2026 from 11 to 13 September 2026 at Defence Expo Ground, Lucknow, at stall B41. On display: the Devsol 740W HDT solar panel, hybrid solar inverters from 1kVA to 15kW, lithium batteries and hybrid solar AC.
What we showed at stall B41
Our stall brought together products for solar generation, storage and cooling so visitors could see the equipment side by side. The display included the solar panel range, hybrid solar inverters, lithium batteries and hybrid solar AC. A product-range and installations screen provided more context at the booth. The photographs below document the display and the team at the event; they are not a record of visitor numbers, sales or performance outcomes.
The inverter display included wall-mounted units and a 12kW unit on a plinth. Devsol-branded lithium batteries were displayed beside the inverters, allowing visitors to see the storage and inverter products in one setting. The hybrid solar AC display carried the line “Solar Power, Cool Air Every Day.” Product selection still depends on the electrical load, installation design and the specifications of the particular model; the stall display itself should not be read as a system design or sizing recommendation.
The Devsol 740W HDT solar panel
The Devsol 740W HDT solar panel product page is the source for the current model specifications: 740W rated power, 23.8% module efficiency at Standard Test Conditions, glass-glass bifacial construction, a Pmax temperature coefficient of −0.24%/°C and 0 to +3% positive power tolerance. It states a 15-year product warranty and a 35-year linear performance warranty, each subject to the applicable terms and conditions. These specifications are not a promise of site-specific energy yield: actual output depends on installation and operating conditions.
HDT (Heterojunction Dual-side Technology) is an Advanced HJT-based dual-side solar architecture engineered to optimise front- and rear-side optical response, surface passivation, current collection, bifacial energy yield and module-level performance.
The panel was part of a broader solar generation and storage display at the Lucknow booth. For a purchase or project specification, consult the linked product record and request the applicable datasheet and written commercial terms for the model being supplied. System design should also account for the electrical and structural requirements of the installation rather than relying on the panel’s nameplate wattage alone.
Photos from REV Expo Lucknow 2026
These photographs were captured on 11 and 12 September 2026 at stall B41. They show the lit Nexus Solar Energy and Devsol booth, the inverter, battery and hybrid solar AC display inside it, conversations at the counter and a group photograph at the stand. The images document the physical display and team presence; they do not establish sales, visitor totals or product performance.
