Solar PV
Does the production become revenue?
Challenge yield, captured electricity prices, PPA terms and curtailment assumptions. Test whether the price still works when output or commissioning changes.
Investment & location decisions · SSI-ENN
Screen the project.
Challenge the investment case.
For PV, wind, PV+BESS hybrids and standalone BESS projects. Use SSI-ENN software to analyse the investment and its location together: identify weak economics, grid constraints and missing evidence before committing capital. Then keep valuation and reporting current as the asset develops and operates.
Coverage across all OECD countries.
Full capability is live for Italy; other countries upon request. Local data, asset type and reporting scope are confirmed for each engagement.

Scenarios, material gaps and a traceable decision
Different assets. The questions that change their value.
One software analysis brings together the project, its market and its grid connection. The scope follows your technology, development stage and investment decision.
Wind
How robust is the operating case?
Review production and availability assumptions alongside grid constraints, operating costs and exposure to weather. Identify what the technical diligence must resolve.
PV+BESS hybrids
Does the combination create value?
Compare solar-only and combined cases. Account for shared connection limits, charging energy, losses and the timing of sales without counting the same energy twice.
Standalone BESS
Which revenues can the battery sustain?
Test market and contracted income, duration, operating costs and battery renewal. Separate achievable cash flow from theoretical market opportunity.
An asset is also a location decision.
SSI-ENN connects project economics with grid-node context, climate exposure and infrastructure dependencies. Use the combined view to shortlist sites, challenge an acquisition price or prioritise the next diligence question.

Project pre-screening & due-diligence preparation
Screen the numbers before you commit capital.
Spot a weak investment case early. Test price, cash flow and required return before deciding what deserves deeper due diligence.
Two BESS portfolio sizes. One hypothetical PV+BESS project.
Examples A and B use real Italian portfolio sizes with invented financial assumptions: one meets a 10% return target, the other misses it. Example C is a wholly hypothetical solar-and-storage project. All prices, cash flows and returns are demonstrations-not project terms, market forecasts or sale offers.
Demo A: €650,000 purchase price + €50,000 additional capex per MW; €100,000 annual net cash flow per MW. Illustrative assumptions only.
Edit the total project amounts below. Cash flow is after operating costs, before tax and financing. Changing examples or resetting reloads its demonstration assumptions.
Solar and storage: one combined investment case.
The €40m base investment is a hypothetical €30m for PV, €8m for BESS and €2m for shared works; an extra €2m is entered separately. The €4.5m annual net cash flow represents the whole project, including an assumed allowance for maintenance and battery renewal. These round figures illustrate the screening process; they are not a build-cost estimate or yield forecast.
For your project, account for charging energy, losses and the PV revenue forgone when electricity charges the battery. Do not count the same MWh as both a PV sale and a battery sale. The flat cash-flow model does not simulate hourly dispatch or the timing of battery replacement; those are due-diligence questions.

- Compare site and grid constraints before investing
- Test revenue, cost, delay and resilience scenarios
- Separate investor cash flow from grid and community value
- Prepare decision, ESG and operating-asset compliance evidence
Does the investment recover its cost of capital?
Cumulative cash flow discounted at your required return, after the upfront investment. The final balance equals NPV.
How much room is there for lower cash flow?
NPV with annual net cash flow 20% lower or higher; price, capex, discount rate, life and terminal value stay unchanged. A sensitivity, not a forecast.
View the chart values in tables
Calculation method and scope
NPV = discounted annual net operating cash flows + discounted terminal value − purchase price or base investment − additional upfront capex. IRR is the discount rate at which NPV becomes zero. Simple payback divides the initial investment by annual cash flow; it is undiscounted, excludes terminal value and is not shown beyond the modelled operating period. The annual break-even cash flow is the constant annual amount needed for zero NPV at your required return.
This is a project pre-screening and due-diligence preparation tool, not a completed due diligence or a project valuation. It uses constant year-end cash flows before financing and tax. Debt, taxes, degradation, changing energy prices, construction delays and replacement capex are not modelled separately. The configured software models relevant scenarios and constraints from the supplied data. Grid or societal benefits are not automatically investor revenue.
Beyond the return: the full asset picture.
SSI-ENN supports decisions from acquisition to operating-asset reporting.
Value & scenarios
What changes the investment case?
Model project economics, compare operating and financing assumptions, and test sensitivities before committing capital.
Benchmarking
How does the asset compare?
Compare assets and portfolio exposures against their market and grid context. Refresh valuations as assumptions change.
Operating-asset reporting
What can you substantiate?
Prepare traceable evidence for CSRD/ESRS, EU Taxonomy and SFDR reporting where applicable. Link disclosures to data and method.
Resilience & climate
Where could availability be lost?
Examine infrastructure dependencies, climate exposure and compound-risk scenarios alongside the financial case.
Grid value
What does the asset contribute to the system?
Assess flexibility, congestion relief and potential services at the relevant grid node. Distinguish system value from contracted revenue.
Societal & ESG impact
Who benefits beyond the owner?
Explore reliability, local economic effects and environmental impacts in a separate community view.
OwnerInvestorCommunityGrid
Distinct views of the same asset. Societal and grid benefits are not automatically cash flow. Reporting scope and applicable requirements are agreed by country and asset; Italian reference workflows are available. Evidence supports, rather than replaces, the responsible reporting and assurance process.
