Frequently Asked Questions?
NJ Engineering focuses on complete EPC execution, quality solar components, professional installation, technical support, net metering assistance and long-term system performance support.
Yes. A properly designed rooftop solar system can generate electricity for on-site consumption and, where applicable, export surplus power through the approved net-metering mechanism, helping reduce grid electricity consumption
Eligible residential customers may receive government subsidy subject to the applicable government scheme, eligibility criteria and current regulations.
Warranty varies by manufacturer and component. Solar modules, inverters and other equipment carry their respective manufacturer warranties, while installation-related warranty is provided as per the project terms.
Yes. We provide technical support, system monitoring, maintenance assistance and after-sales service for installed rooftop solar systems.
Solar systems require periodic panel cleaning, visual inspection, electrical checks and performance monitoring to maintain efficient generation.
The installation timeline depends on system capacity, site conditions, material availability and required electrical approvals. The project schedule is confirmed after the site survey and order confirmation.
Yes. NJ Engineering provides assistance with the solar application and net metering process, subject to applicable DISCOM/MSEDCL procedures and approvals.
Yes. NJ Engineering can provide solar panels, inverters, ACDB, DCDB, L&T meters, electrical materials, mounting accessories and other rooftop solar components as required for the project.
A typical EPC project includes engineering and system design, solar modules, inverter, mounting structure, DC/AC electrical equipment, protection devices, cabling, earthing, installation, testing and commissioning.
System capacity is determined based on electricity consumption, electricity bills, sanctioned load, available rooftop area, shadow analysis and the customer's energy requirements.
Yes. We provide rooftop solar EPC solutions for homes, apartments, commercial buildings, offices, factories, industries, institutions and other properties.
NJ Engineering provides end-to-end rooftop solar EPC solutions, including site survey, system design, solar material supply, installation, electrical work, testing, commissioning, net metering assistance, and after-sales support.
A Rooftop Solar EPC company provides complete Engineering, Procurement and Construction services, including system design, equipment supply, installation, testing, commissioning, and project support.
We provide On-Grid, Hybrid and Solar Battery Storage solutions based on the customer's electricity requirements and site conditions.
NJ Engineering offers complete solar power solutions including On-Grid Solar Systems, Off-Grid Solar Systems, Residential Solar, OPEX Solar Power Plants, and Open Access Solar Power Plants for residential, commercial, and industrial clients.
An on-grid solar system is connected to the utility grid and allows you to use solar power during the day while exporting excess electricity to the grid through net metering, helping reduce electricity bills.
An off-grid solar system operates independently of the electricity grid and uses batteries to store solar energy. It is ideal for remote areas, rural locations, and places with unreliable power supply.
In an OPEX solar model, NJ Engineering invests in, installs, operates, and maintains the solar power plant. The customer pays only for the energy consumed at a fixed, lower tariff without any upfront investment.
Open access solar allows businesses to purchase solar power from large solar plants through the open access mechanism. It is suitable for high-power consumers looking for long-term cost savings and sustainability.
