Net metering with MSEDCL
Net metering lets the plant export surplus units and offsets them on your bill. Eligibility and limits depend on current state rules; we handle the application and tell you what applies to your connection.
Industrial Rooftop Solar EPC in India
WRS designs, installs and maintains solar plants for factories, MSMEs and government projects. Pay upfront and own the plant, or go zero-investment with RESCO. Add battery storage to use solar after sunset, and energy audits to find where power is wasted.

Your options
Rooftop solar (capex)
WRS designs, installs and maintains rooftop solar plants for factories, so you generate power on your own roof and cut your grid bill. You own the plant and keep the savings.
Is this right for you?
- You pay a significant monthly power bill and run mostly in the daytime.
- You have a strong, shadow-free roof or a roof that can be strengthened.
- You want to own the asset and keep every unit it generates.
- You want to use the tax benefits available to owners of solar assets (confirm the current rules with your chartered accountant).
How a rooftop project runs
- Site survey and roof load checkWe measure the usable roof, check its strength and the shading, and study your load profile.
- Design and yield studyA layout and generation estimate for your site, with the system size that suits your daytime load.
- Approvals and net meteringWe prepare and follow up the MSEDCL net-metering application and other approvals.
- InstallationIn-house engineers install the structure, modules and inverters, with quality checks at each stage.
- CommissioningTesting, grid synchronisation and handover with documentation.
- O&M and monitoringCleaning, inspections and performance monitoring, so the plant keeps producing as designed.
What to know before you decide
Accelerated depreciation
Businesses that own solar assets may be able to claim accelerated depreciation. The rate and eligibility change, so confirm them with your chartered accountant.
Roof load checks
Every roof is checked for strength and condition before design. Mounting is chosen for your roof type, and weak sections are flagged before any work starts.
What it costs and what you save
Cost depends on system size, roof type and structure, and savings depend on your tariff and daytime load. After the free assessment we send a written proposal with system size, cost, annual savings and payback. For a quick indication, try the savings calculator.
RESCO / OPEX (zero investment)
Under the RESCO model, WRS builds and runs the plant and you pay only for the power it produces. No upfront cost. Depending on your site and financial profile, the tariff can be set below your grid rate.
Is this right for you?
- You want lower power costs but prefer not to spend capital on a plant.
- You have a suitable roof or land and a steady daytime load.
- You would rather not manage operation and maintenance yourself.
- You are comfortable with a long-term power purchase agreement.
How RESCO works
- We assess your site and loadWe check your roof or land, your load and your current tariff.
- WRS builds and owns the plantWRS funds, designs and installs the plant on your premises.
- You buy the power it producesYou pay a per-unit tariff for the solar power you use, agreed in advance.
- WRS operates and maintains itMonitoring, cleaning and repairs are WRS's responsibility for the contract term.
The commercial terms, in plain language
Per-unit tariff versus your grid tariff
You pay for solar units at an agreed rate. Depending on your site and financial profile, that rate can be set below the grid tariff you pay today, so you save from the first bill.
Contract term
RESCO contracts run for an agreed period. The term and any tariff escalation are set out in the agreement before you commit.
Who maintains the plant
WRS operates and maintains the plant for the contract term, at no extra charge to you.
Buy-out option
Buy-out terms, if you later want to own the plant, are agreed in the contract.
What it costs and what you save
There is no upfront investment. The tariff and contract term depend on your site, load and financial profile, and we set them out in a written proposal after the free assessment.
Ground-mounted and open access
When your roof is too small, or your load is too big, a ground-mounted plant can supply your factory directly (captive) or through the grid (open access). WRS also builds ground-mounted plants for government tenders.
Is this right for you?
- Your power use is larger than your roof can supply.
- You can offer land for a captive plant, or buy green power through open access.
- You are a government body or developer with a ground-mounted solar tender.
- You want a larger share of your power from solar than a rooftop allows.
How a ground-mounted project runs
- Land and load studyWe assess the land, the terrain and your consumption.
- Design and yield studyLayout, structure and generation estimate for the site.
- ApprovalsGrid connection and the approvals needed for captive or open-access supply.
- ConstructionFoundations, structures, modules, inverters and evacuation.
- CommissioningTesting and handover with documentation.
- O&M and monitoringOperation and performance monitoring through the plant's life.
What decides whether it works
Land
You need suitable, unshaded land with a clear title, close to a grid connection point.
Transmission and wheeling charges
For open access, the charges for moving power through the grid affect your delivered cost. We model them before you commit.
Eligibility
Captive and open-access eligibility depends on your connection and on state rules. We confirm what applies to you.
Green energy open access rules
State green-energy open-access rules change. We keep up with them and build them into the proposal.
What it costs and what you save
Costs depend on land, plant size, grid connection and the supply model. We set out the cost, expected generation and payback in a written proposal after the free assessment.

Agrivoltaics
Agrivoltaics lets a farm produce electricity and crops from the same land. WRS designs solar for farms and agricultural projects, with a focus on Africa.
Read moreBattery storage
Batteries store solar power so you can use it after sunset, ride through outages and run less diesel. WRS can supply storage as a project or as a service.

The cheapest unit of power is the one you do not use. WRS audits where your plant uses and wastes energy, ranks the fixes, and sizes solar to the reduced load.
