Solar cleaning CAPEX vs OPEX — which model fits your plant?
IPP and CPSU teams evaluate robot purchase (CAPEX + AMC) against Taypro OPEX (pay per panel cleaned). This page compares balance-sheet impact, mobilisation speed, audit trails, and 5-year TCO — not just sticker robot price.

Commercial models
Robot CAPEX + AMC vs Taypro OPEX
Robot CAPEX + AMC
Purchase the fleet. Own depreciation, residual value, and spare inventory policy. Taypro commissions, trains operators, and maintains robots under structured AMC with NECTYR included.
India robot CAPEX bandsTaypro OPEX service
No upfront robot purchase. Pay monthly for verified panels cleaned — ideal when balance-sheet efficiency and fast mobilisation matter more than asset ownership.
OPEX service detailsQuick answer
When to choose robot CAPEX vs Taypro OPEX
Robot CAPEX means you purchase GLYDE, GLYDE-X, NYUMA, NYUMA-X, or HELYX, depreciate the fleet on your balance sheet, and contract structured AMC for uptime. Taypro OPEX means Taypro retains fleet ownership — you pay monthly for panels actually cleaned, reconciled through NECTYR telemetry.
Many Indian IPPs start with OPEX to mobilise quickly without capital approval, then transition to owned fleets on long-hold assets after 3–5 years of proven PR recovery. CPSU and SECI-tendered plants often model both scenarios in parallel using the same soiling and tariff assumptions.
Compare on ₹ per recovered MWh over 5–20 years — not robot unit price alone. Manual wet washing on a 10 MW arid site typically runs ₹45–80 lakh per year all-in; robotic programmes convert cleaning to measurable per-panel economics with 3–10 dry cycles monthly.
Both commercial models include NECTYR block-level cleaning logs — the audit layer lenders and internal O&M governance ask for at 50 MW scale. Electrical O&M, inverters, and tracker mechanical work stay with your existing contractor; Taypro owns the cleaning execution layer.
Discount rates of 10–14% are common in Indian utility finance models when comparing 5-year TCO. Use the ROI calculator below with your MW, tariff, and installation type, then request a site-specific soiling study for binding terms.
Decision matrix
CAPEX vs OPEX procurement comparison
Use this matrix in RFQ and investment committee packs. Rates and CAPEX bands are directional — binding terms follow a site soiling study.
| Factor | Robot CAPEX + AMC | Taypro OPEX |
|---|---|---|
| Balance sheet | Capitalise fleet; depreciate over plant life | Operating expense; no robot asset on books |
| Mobilisation | Commissioning + operator hire; capex approval cycle | Faster — Taypro owns and deploys fleet |
| Cost predictability | AMC escalation; spare parts ownership | Per-panel rate (₹0.45–0.70/cycle) × verified volume |
| Cycle frequency | You schedule; uptime and spare risk | Contractual 3–10 dry cycles/month typical |
| Lender / audit | NECTYR logs + owned asset register | Monthly panel-volume reconciliation in NECTYR |
| Best hold period | 15+ years on very large fleets | 3–10 year IPP holds; balance-sheet sensitive sponsors |
Hybrid paths
OPEX first, CAPEX later — a common IPP pattern
Several Indian IPPs contract Taypro OPEX for the first operating seasons to prove PR recovery and NECTYR audit trails, then transition to owned fleets on assets they plan to hold 20+ years.
SECI and state discom tenders increasingly ask for evidence of cleaning coverage — not just a line item for manual washing. Both CAPEX and OPEX models deliver NECTYR block-level logs; the difference is who owns the robot asset.
Tracker plants carry higher per-panel economics (1.8× OPEX multiplier vs fixed tilt). Model this in both scenarios before committee sign-off.
The finance question
Are you optimising for balance sheet or for speed to PR recovery?
OPEX preserves gearing and mobilises in weeks. CAPEX suits long-hold owners who amortise robots over 15–20 years. Many portfolios use both — OPEX on new acquisitions, CAPEX on core assets.
Procurement workflow
How to model CAPEX vs OPEX for your plant
Five steps finance and O&M teams use before signing a cleaning contract.
Gather plant and finance inputs
MW capacity, state, fixed tilt vs tracker, module Wp, PPA or merchant tariff, hold period, and current annual cleaning spend.
Estimate soiling and cycle count
Use regional benchmarks (8–25% seasonal loss without systematic cleaning) or a Taypro soiling study. Choose 3–10 cycles/month for dry robotic programmes.
Run parallel CAPEX and OPEX scenarios
Use the ROI calculator with both procurement models. Compare 5-year TCO at your discount rate (10–14% illustrative).
Review audit and SLA requirements
Confirm NECTYR reporting meets lender or SECI technical due diligence. Define breakdown response and coverage evidence.

Model fit
CAPEX vs OPEX — quick fit guide
OPEX often wins when
- You need fast mobilisation without capex committee approval
- Hold period is under 10 years or balance-sheet gearing is constrained
- You want opex tied to verified panels cleaned, not lump-sum crew contracts
- Portfolio has mixed MW sizes and you want one accountable vendor
CAPEX often wins when
- Hold period exceeds 15 years on 50 MW+ core assets
- You have in-house O&M capacity to own spares and fleet depreciation
- You already own robots and only need AMC + NECTYR upgrade

Solar cleaning CAPEX vs OPEX — FAQ
Common questions from IPP finance and O&M procurement teams.
CAPEX means purchasing robots and owning depreciation plus AMC. OPEX means Taypro owns the fleet and you pay monthly for panels cleaned, verified in NECTYR.
When hold period is shorter, capex approval is slow, or you want opex aligned to verified cleaning volume. Run both scenarios in the ROI calculator with your tariff.
Hybrid transitions are common after 3–5 years of proven performance. Discuss fleet purchase options during commercial engagement.
Yes. Taypro OPEX is all-in for operators, robots, spares, SOPs, and NECTYR — you pay for panels cleaned, not idle hours.
Many prefer auditable per-panel billing with NECTYR coverage logs over opaque manual crew contracts.
Indian utility models often use 10–14% illustrative. Your treasury team should set the rate for investment committee packs.
Manual wet costs on 10 MW arid sites often run ₹45–80 lakh/year and scale linearly with MW. Compare on ₹ per recovered MWh over 5 years.
Tracker geometry adds cost per cycle (1.8× OPEX multiplier). Both models remain viable — model tracker-specific inputs in the calculator.
OPEX programmes typically start around 10 MW utility scale. Smaller sites may face minimum monthly programme fees.
Yes. Robot CAPEX programmes include NECTYR fleet portal for scheduling, coverage audits, and AMC ticketing.
Tenders increasingly require documented cleaning coverage. Both models can meet technical diligence with NECTYR evidence — choose based on balance-sheet preference.
