[Request a CAPEX Proposal](https://arraysingenieria.com/free-solar-quote/?service=capex) See a plant our client owns What CAPEX Means ## Your plant, your savings, from day one Under the **CAPEX model** your organisation pays for the solar plant and owns it. There is no long-term power purchase agreement and no per-unit tariff to a developer: the electricity the plant produces replaces power you would otherwise buy from the grid or from diesel generators. Arrays Ingenieria delivers CAPEX plants end to end. We are an **installation, EPC and civil company**: we do not manufacture modules or inverters, so we are free to specify **Tier-1 equipment** from established manufacturers, or the makes your engineers or lead EPC have approved, and put all our effort into building the plant properly. ### What you get - Site survey, load study and system design - Tier-1 modules, inverters and balance-of-system equipment - Civil works as the site needs: pile foundations, RCC, boundary walls and fencing - Mechanical and electrical installation, earthing and lightning protection - Support with net-metering, DISCOM and Electrical Inspector (CEIG) approvals, as agreed in the contract scope, plus testing and commissioning - Handover documentation, and O&M support if you want it ### Why businesses choose CAPEX Owning the plant often gives the lowest lifetime cost of power, because no developer margin is built into a tariff. The real result depends on your finance cost, tariff, roof or land, and how well the plant is maintained. A business that owns the plant may also claim **accelerated depreciation** under the Income Tax Act, which lowers tax in the early years; check the current rate with your tax adviser. ## At a glance Model: **CAPEX: you own the plant** We deliver: **Design, supply, I&C, civil** Equipment: **Tier-1, not own-brand** Plants: **Rooftop & ground-mount** Assurance: **ISO 9001, 14001, 45001** ## Thinking of owning your plant?

An honest comparison. We build on the CAPEX model; if you prefer OPEX, the developer you sign with can still engage us to build the plant. | | CAPEX (you own) | OPEX / RESCO (developer owns) | | --- | --- | --- | | Upfront investment | You pay for the plant | None; the developer invests | | Who owns the plant | You, from commissioning | The developer, for the contract term | | What you pay afterwards | No per-unit tariff; you bear upkeep, insurance and any loan repayments | A per-unit tariff for many years | | Lifetime savings | Often higher: savings are not shared with a developer, but depend on finance and upkeep | Usually lower: the tariff includes the developer's return | | Tax benefit | Accelerated depreciation for businesses | Goes to the developer | | Best for | Organisations with capital or bank finance | Organisations that cannot invest upfront | | Arrays Ingenieria's role | Your EPC contractor, end to end | Installation & EPC partner to the developer | How It Works ## From Survey to Switch-On - 1 **Site survey & load study** We study your roof or land, your load profile, your grid connection and any diesel generators. - 2 **Design & proposal** A system design, bill of quantities and a clear scope of work, so you know exactly what you are paying for. - 3 **Procurement** Tier-1 modules, inverters and balance-of-system equipment, to our specification or your approved makes. - 4 **Civil & installation** Piling or roof works, structures, modules, cabling, earthing and lightning protection, run by ex-servicemen site teams. - 5 **Approvals & commissioning** Net-metering and DISCOM approvals, testing, grid synchronisation and commissioning. - 6 **Handover & support** As-built documents and training for your team, with O&M support available. Ownership ## Under CAPEX, You Own Everything You pay Arrays Ingenieria to build the plant. From commissioning, it is yours. | Item | Who owns it under CAPEX | | --- | --- | | The solar plant: modules, inverters, structures, cabling | You | | Every unit of electricity it generates | You: used on site or exported to the grid | | The savings on your power and diesel bills | You, for the life of the plant | | Tax benefit (accelerated depreciation, for businesses) | You | | Manufacturers' equipment warranties | Issued for your plant, handed over to you | | The roof or land | Stays yours; nothing is leased to anyone | | Upkeep after handover | Your responsibility; our O&M service is optional | | Arrays Ingenieria | Paid once to design, supply, build and commission the plant; owns nothing in it | Proof ## A Plant Our Client Owns [Tea Estate · Ground-Mount: **Jay Shree Tea: 1 MW Solar at Towkok & Manjushree Tea Estates**1035 kWp (535 + 500 kWp) · Sonari, Charaideo district, AssamRead the case study](https://arraysingenieria.com/project-jayshree-tea-1mw-solar-assam/) Questions ## CAPEX Solar FAQ Do you offer OPEX, RESCO or zero-investment solar? No. We build plants that our clients own. If you want an OPEX arrangement, the developer that finances the plant can engage us as its installation and EPC partner, as Tata Power Renewable Energy and Sustvest have done. Do you manufacture the panels and inverters? No. We are an installation, EPC and civil company. We specify Tier-1 equipment from established manufacturers, or the makes your engineers approve. Can you work with our own engineers or consultant? Yes. We regularly build to specifications and approved makes set by the client or the lead EPC, such as Tata Power.
