Solar ROI and battery sizing for a 100-ton shrimp farm
Aeration is the single largest energy load on a shrimp farm and it never stops. That makes shrimp one of the highest-return use cases for solar + battery in aquaculture — but only if the PV array is sized against the real 24-hour aeration profile, and the battery is sized against the longest no-PV window, not the average day.
Solar ROI drivers
Every liter of diesel avoided at $1.00–$1.60/L compounds across 20 years. On tropical sites, PV + battery typically displaces 60–90% of diesel consumption, driving 3.5–5.5-year simple payback on the energy block.
5.0–6.0 kWh/m²/day sites hit 14–22% 20-year IRR in the Base scenario of the Solar ROI calculator. Below 4.2 kWh/m²/day or on subsidized-diesel grids, payback stretches beyond 7 years.
Sizing PV alone against average daytime consumption undersizes the system for shrimp. Size the array against total daily kWh × 1.15 losses, then let the battery bridge the night.
Use Pessimistic (low irradiance, high CAPEX, low fuel), Base and Optimistic in the Solar ROI calculator. Lenders want the Pessimistic case to still cover DSCR ≥ 1.30.
Battery sizing drivers
Emergency aeration for 100-ton production is typically 60–75% of peak farm load. Battery kWh = critical kW × autonomy hours ÷ depth-of-discharge (0.90 for LFP).
A hybrid farm with a small backup genset only needs to cover the nightly gap. Zero-diesel targets need to survive back-to-back cloudy days, which typically doubles the kWh.
6,000–10,000 cycles at 90–95% DoD means one LFP bank outlives 3–4 lead-acid replacements. TCO over 10 years is 30–50% lower despite higher CAPEX.
A 92% round-trip LFP system delivers ~8% more useful energy per PV kWh than an 85% lead-acid system — which directly shrinks the PV array required for the same aeration hours.
Key inputs to get right
Solar ROI and battery sizing outputs are only as good as four core inputs. Small changes here move CAPEX, payback and diesel offset by 20–40%.
Hour-by-hour demand of aerators, pumps, RAS loops, chillers, lighting and hatchery equipment. Peak vs. average and day/night split decide PV size, inverter rating and how much battery you actually need.
How long critical loads (aeration, oxygenation, biofilter circulation) must run with no sun and no grid. Typical: 4–8h for grid-tied hybrid, 12–24h for remote off-grid. Every extra hour multiplies battery CAPEX.
LFP (LiFePO₄) for most aquaculture sites — 6,000+ cycles, safer thermal profile, 80–90% usable depth of discharge. NMC only where energy density matters. Lead-acid rarely justified except for very short backup windows.
Grid tariff (USD/kWh), diesel price (USD/L), genset efficiency (kWh/L), any time-of-use or demand charges, and expected annual escalation. These drive the avoided-cost side of the ROI model and separate a 4-year payback from a 9-year one.
From load profile to a bankable battery spec — in 5 steps
Use this walkthrough to translate your 24-hour load curve into a defensible chemistry, usable-kWh and autonomy spec you can drop straight into an RFQ. All five steps map to inputs in the embedded Solar ROI + Payback and Battery Storage calculators above.
- 1Isolate the critical load, not the total load
Split your 24 h kW curve into critical (aeration, oxygenation, biofilter circulation, incubators, alarms) and comfort (lighting, office, non-essential pumps). Battery sizing works off the critical curve only — usually 60–75% of peak farm load. Comfort loads get shed automatically when the battery falls below the reserve threshold.
- 2Choose autonomy hours from the biology, not a round number
Grid-tied hybrid with genset backup: 4–8 h. Off-grid or unreliable grid: 12–24 h. Hatcheries and broodstock: 16–48 h. Anchor the number to two hard limits — the biofilter's safe no-flow window (nitrification integrity, typically 30–60 min) and the dissolved-oxygen ride-through of your densest pond or tank. Every extra hour multiplies battery CAPEX almost linearly.
- 3Pick chemistry — default to LFP
LFP (LiFePO₄) is the default for aquaculture: 6,000–10,000 cycles, 90–95% usable depth-of-discharge, safe thermal profile near live animals, and 30–50% lower 10-year TCO than lead-acid despite higher CAPEX. NMC only where energy density matters (rare on a fixed site). Lead-acid is only defensible for very small (<50 kWh) UPS blocks on SCADA and alarms.
- 4Convert to usable kWh with the sizing formula
Usable kWh = Critical kW × Autonomy hours ÷ Depth-of-Discharge ÷ Round-trip efficiency. For LFP use DoD = 0.90 and round-trip = 0.92. Example: 120 kW critical × 10 h ÷ 0.90 ÷ 0.92 ≈ 1,450 kWh usable. Nameplate kWh is that number ÷ DoD again if the vendor quotes gross capacity — always confirm which one the datasheet lists.
- 5Stress-test against Pessimistic / Base / Optimistic
Rerun the Solar ROI + Payback calculator with lower irradiance (−15%), higher CAPEX (+15%) and lower fuel/tariff (−20%). The Pessimistic case must still deliver DSCR ≥ 1.30 for senior debt and keep autonomy above the biological minimum. If it doesn't, either shrink comfort loads, add PV, or reduce autonomy hours — not the critical-load battery.

Bankability questions
- Is the site's annual solar irradiance (kWh/m²/year) verified with satellite + on-site data?
- Is the water source characterized (salinity, temperature, seasonality) and permitted for withdrawal and discharge?
- Is aeration load modeled hour-by-hour to correctly size PV, battery and diesel backup?
- Is SPF post-larvae supply secured with at least two qualified hatcheries?
- Is a qualified farm operator identified with prior semi-intensive shrimp experience?
- Is CAPEX supported by class-3 estimates from at least two independent RFQ respondents?
- Is 10-year fuel savings from PV + battery modeled at pessimistic, base and optimistic scenarios?
- Is the financing structure matched to project ramp-up cash flow (senior debt + green / blue-economy tranche)?
Key project risks
- Aeration under-sizing = mass mortality. Never cut PV/battery scope below full critical load.
- PL quality variability materially affects survival — dual-source and screen.
- Diesel price volatility is a positive lever here (PV hedges it), but insurance and O&M discipline matter.
- Pond biosecurity discipline is the difference between profit and loss.
