Before you progress

Confirm interval building demand and import limits.
Validate charging demand, installation costs and all tariff fees.

Assumptions & limits

Declared charger use and electrical headroom; no traffic forecast or connection approval.
Inputs are unverified. EUR only; no automatic currency conversion or jurisdiction-specific entitlement is inferred.
Constant year-end pre-tax unlevered cash flows. No inflation, degradation, financing, tax, replacement or terminal value. Payback is not a return guarantee.
Concurrency is an enforced aggregate output limit, not a promise about coincidental arrivals. Charging losses increase grid demand.
Utilisation is a user scenario, not forecast traffic. Include network, payment, maintenance and other fees in the stated costs. No solar contribution is assumed.

Built for your business. Useful to your visitors.

Property portals

Add energy screening beside an industrial-property or operating solar-asset listing. Prefill the property’s published facts and let visitors explore their own demand or investment assumptions.

Listing data is editable and is never presented as independently verified.

EPC websites

Give plant owners a first repowering or direct-wire comparison before they request a proposal. Receive the selected scenario and assumptions with their enquiry.

Production, equipment suitability and construction scope still need your engineering review.

O&M websites

Help customers explore the value of a proposed upgrade. With Business, replay supplied hourly export against a changed capacity and export limit.

Use the results to scope diagnostics and compare repair with replacement.

Three ways to integrate

01 · EMBED

Copy into your website

Use a hosted iframe on WordPress, Webflow or a custom site. No API key goes into the page. Register the exact website origin where it may appear.

02 · COMPONENT

Connect a listing

A small JavaScript component mounts the calculator, prefills supported inputs and emits a completion event. Your visitor can review every value before calculating.

03 · API / PRIVATE PORTAL

Connect your software

Submit scenarios from your backend with a scoped API key. Business also accepts aligned hourly profiles. Existing asset API access remains separately permissioned.

Try the visitor experience

These examples use illustrative EUR inputs. They are not a forecast for a real property and do not send enquiries.

Change the inputs to explore the assumptions.

Choose the integration depth you need

Loading plans…

Prices in EUR per month, excluding VAT where applicable. Allowances are shared across your workspace and reset each UTC calendar month. No rollover, automatic overage or charge for an exact retry within 30 days. These plans cover widget screenings; full workspace assessments and asset access have their own entitlements.

Free is available to signed-in workspace administrators. Paid plans are available by arrangement; online paid checkout is not enabled.

Your website widgets

Create a widget, copy its integration code and review enquiries that visitors choose to share. Visitors can see results without providing contact details.

Business server key

Create a key limited to widget calculations. Copy it now; it will not be shown again. Keep it on your server.

Shared enquiries

Only visitor-confirmed submissions appear here. Enquiries are available for 90 days; download them if you need to retain them under your own policy. No email or CRM delivery is automatic.

For your developer

The component supports reviewed prefill and a completion event. It never sends a visitor’s financial result to the parent page automatically. Business API keys stay on your server.

Component example · Pro and Business

<div id="pv8-assessment"></div>
<script src="https://pv8.ai/ui/widgets/component.js"></script>
<script>
const widget = PV8Widgets.mount({
  target: '#pv8-assessment', widgetId: 'YOUR_WIDGET_ID',
  prefill: {country: 'CZ', annual_generation_mwh: 1100},
  onComplete: () => console.log('Assessment completed')
});
// Later: widget.update({annual_generation_mwh: 1200});
// On route change: widget.destroy();
</script>

Server API example · Business

POST /api/v1/widgets/YOUR_WIDGET_ID/assessments
Authorization: Bearer YOUR_SERVER_KEY
Idempotency-Key: a-unique-key-for-this-input-set
Content-Type: application/json

{
  "country": "CZ", "currency": "EUR",
  "annual_generation_mwh": 1100,
  "proposed_generation_mwh": 1350,
  "energy_value_eur_mwh": 75,
  "capex_eur": 140000, "incremental_opex_eur_year": 1000,
  "term_years": 20, "discount_rate_pct": 7
}

Use the run:widgets scope. Create a widget-only key above or with POST /api/v1/widgets/keys while signed in. Revoke it with DELETE /api/v1/keys/{id}. Use a new idempotency key when inputs change. Failed validation does not consume an assessment.

Hourly profiles contain one complete UTC calendar year of consecutive hourly MWh values (8760 or 8784). Supply the generation series and, for direct wire, an aligned demand series. The OpenAPI contract defines the fields and required scenario assumptions.

Choose an EU-27 country, Japan, Turkey or Australia as the review jurisdiction. All widget money inputs and outputs are explicitly EUR. Local permits, support arrangements, taxes and supply rules require a separate review.
