Independent technical advisory · Solar PV · Battery storage · Hybrid power
Credit decides which projects get financed. Physics decides which ones keep paying.
We review solar, storage and hybrid projects the way the plant will actually run: hour by hour, at site temperature, under the contract you are about to sign. Then we tell you, in numbers, what it means for the money.
Finding. A "400 MWh" battery misses its 300 MWh contract from year 3. Tender about 430 MWh, or price augmentation in before close. Run it with your numbers

Where projects go wrong
The costly gaps sit between documents that each look fine
A yield report, a single-line diagram, a PPA and a financial model are written by different people at different times. We read them against each other. These are the checks that most often change a decision.
PPA ↔ plant
Contracted capacity against installed AC
Modules are rated in DC, contracts in AC, and the export limit is a third number. We have seen inverter capacity sit well below what a PPA committed the plant to deliver.
500 MWp of modules → 414 MWac of inverters → 314 MW export cap. Three correct numbers for three points in the chain. Compare like with like.
Yield ↔ debt
A P90 that sits too close to P50
Lenders size debt on P90. If a report shows P90 only 2–3% below P50, an uncertainty term has usually been left out, often year-to-year weather.
Combined uncertainty = √(4² + 5² + 3² + 3² + 1²) = √60 ≈ 7.75%
P90 = P50 × (1 − 1.282 × 0.0775) ≈ 0.90 × P50
Motor ↔ inverter
Motor starts on an inverter-fed bus
On the grid, a large motor start is a non-event. On inverters alone, the same start can trip every drive in the plant. Average load does not size the inverter.
315 kW motor started direct on line: 6.5 × rated ≈ 2.5 MVA
Dip ≈ 2.5 ÷ 100 MVA of grid = 2.5%
Dip ≈ 2.5 ÷ 10.7 MVA of inverters = 23%
Warranty ↔ COD
Cover that starts before the plant does
Equipment warranties often start at shipment. Batteries sitting in a hot port age before they are installed. The EPC contract has to close the gap to commercial operation.
A 10-year warranty that starts at shipment, with COD 6 months later, gives the owner 9.5 years of cover. We check who carries the gap.

Lenders, funds and arrangers
Before the credit committee
A fixed-fee technical check on a single loan, or a fast, independent read of a data room. Findings ranked by what they do to cash, written for a credit paper.

Before you sign an EPC proposal
Independent review of solar, battery and hybrid quotes against your load, your process and the contract. Strongest on 24/7 plants with large motors and generators.
Quote and design review →Developers and owners
On the owner's side of the table
Design basis, employer's requirements, bid evaluation, guarantees and acceptance tests, so the plant you receive is the plant you specified.

Every finding comes with its number, its cost and its fix
"The battery margin looks thin" is an opinion. A finding states the physical effect, the money effect, the effect on debt service, who carries the risk and what resolves it. Every Linden Hof review is written this way, so it can go straight into a credit paper or a negotiation.
- Physical
- 319 MWh deliverable against a 300 MWh block: 6% margin, used up by fade in about two years
- Money
- Firm block missed from year 3; penalties or lost capacity payments
- Finance
- Fix adds about USD 7.5m CapEx; minimum DSCR 1.38 → 1.35
- Risk holder
- Sponsor, unless the EPC guarantees usable energy at the grid
- Resolution
- Tender about 430 MWh at day one, with pre-built augmentation bays
