Services for solar PV, one decision each

Owners and operators of solar PV systems, from rooftop to utility-scale, can run a free health check or order a scoped service: a warranty projection, a check on signed evidence, an end-of-life route, or a material balance. Each service states what you provide, what you get, and which figures are verified and which are modelled.

Size classes used on every page: residential (≤ 10 kW) · commercial and industrial (> 10 kW to 1 MW) · utility-scale (> 1 MW). Pricing is on request, except PV Health Score, which is free.

PV Health Score

For owners and operators of residential, commercial and utility-scale PV who want a first read on how a system is performing · free, in your browser

Free

What you provide

  • A CSV of energy, daily or monthly, exported from your inverter or monitoring portal. Irradiation is optional.
  • The system size in kWp (DC).
  • An expected yield in kWh per kWp per year. PVGIS and NASA POWER publish reference data you can look up yourself; the tool does not fetch it for you.
  • Optionally, a tariff in US$ per kWh to value the findings. It is your assumption, not ours.

What you get

  • A score from 0 to 100 with these subscores: performance (actual against expected energy), trend (annual change in normalised performance), availability (days with no production in sun hours) and data quality.
  • Findings with an indicative value in US$ per year, at the tariff you enter.
  • Your file is read in your browser. It is not uploaded to our servers.

Verified and modelled

  • VERIFIED The trend is read against published field data. A 2013 review of 1,751 field-measured crystalline-silicon rates has a median of 0.5 %/year (Jordan and Kurtz 2013, Fig. 2b). A 2016 compendium of more than 11,000 rates gives a median of 0.5–0.6 %/year for crystalline silicon (Jordan et al. 2016, abstract).
  • ESTIMATED The score, subscores and findings are our calculation. Weights and rules are shown in the tool. The expected yield and the tariff in US$ per kWh are inputs you set.

02

Warranty Guard

For owners of systems under a module power warranty, and for asset managers checking a portfolio against its warranty terms · on request

Projection

What you provide

  • The warranty's retention terms as written: for example the share of rated output at year 10 and year 25, or one end-of-warranty figure. You can also choose a generic template.
  • A degradation rate: a measured loss over a period, or an assumed rate per year.
  • The module power in W and the module age in years.

What you get

  • A projected year in which output falls below the warranted curve (P50), and the probability of staying inside the warranty at the end of its term.
  • A p05–p95 band drawn against the warranted curve, and the margin today, in percentage points.

Verified and modelled

  • VERIFIED A warranty can be stated as a linear term with one end-of-warranty figure, for example 85% of rated output after 25 years (Solar Victoria, section 8, "Panel warranty from manufacturer"). A high-quality panel is expected to keep at least 80% of its original rating after 25 years (Solar Victoria, section 8, "Panel warranty from manufacturer"). Module working life is typically defined as output falling to between 80% and 70% of the initial power rating (IEA PVPS Task 13, 2014, chapter 3).
  • VERIFIED Measured degradation is not always linear. In a five-year field study of early-life modules, mean and median degradation were both −0.6 %/year, and degradation was highly nonlinear over time (Sandia National Laboratories, Lab News article, results paragraph).
  • VERIFIED An EU JRC preparatory study (Task 8, 2019 draft) found that manufacturers' degradation claims, and the power guarantees tied to them, have no standardised basis.
  • VERIFIED IEC 61215-1 states that its test results are not construed as a quantitative prediction of module lifetime (clause 1, Scope).
  • ILLUSTRATIVE The warranty templates are generic shapes. They are not any manufacturer's terms. We do not hold, read or verify your warranty document.
  • ESTIMATED Projected years, probabilities and bands come from our degradation model and the rate you enter.

03

Verify

For anyone who receives a signed evidence package from a provider, such as a buyer, lender or insurer, and needs to confirm that it was not changed after signing · on request

Signed evidence

What you provide

  • The evidence package: a manifest in the open LTB-Evidence-Manifest/0.1 format, the files it lists, and its Ed25519 signature.
  • The key ID named in the package, to compare with the public key published on the Verify page (key ID ltb-2026-08).

What you get

  • A SHA-256 hash for each listed file, recomputed in your browser and compared with the manifest.
  • An Ed25519 signature check against the published public key.
  • A pass or fail for each check. The sample package passes; a copy with one altered bit fails.

Verified and modelled

  • The check is deterministic: the same file and the same key always give the same result. It runs in your browser.
  • No figure in Verify is modelled. The check proves that the files match what the holder of the signing key signed. It does not prove that the content is true, or that the measurements in it are right.
  • The sample package is signed with the published key ltb-2026-08 and uses illustrative data. It describes no real system.
  • Trusted timestamping (RFC 3161) is not implemented yet. Packages do not carry a trusted timestamp today.

The Loop and Route Grader

For owners and asset managers deciding what happens to a system or its modules at end of life, after a failure, or at repowering · on request

End of life

What you provide

  • The scope: the array's nameplate power in kWp, and the age in years of its modules and inverter.
  • Condition data where you have it: measured power against nameplate, visible defects per module, the hot-spot share from an infrared survey, and insulation status.
  • Your own values for used-module price, test, sort and pack, removal and transport, and net recycling cost. Each one is an assumption, marked as such.

What you get

  • The routes on one common basis: keep operating, repower and resell modules, reuse off-grid or in small loads, and recycle.
  • Each route is valued in US$ per W of nameplate. A route blocked by an insulation fault is listed last and is not ranked.
  • The assumptions behind each route, listed next to its result with their provenance.

Verified and modelled

  • VERIFIED In the EU, PV panels are in scope of the WEEE Directive (2012/19/EU, Annex IV point 4). From 15 August 2018, the recovery target for the WEEE categories that include PV panels is 85%, and the target for preparation for re-use and recycling is 80% (Annex V, Part 3). No PV-specific collection rate is in force. The Commission must assess by 31 December 2026 whether the Directive needs revising (Directive (EU) 2024/884, Article 24a).
  • VERIFIED A suggested screening threshold for reuse is 70% of initial module power. It comes from a PV CYCLE and imec/EnergyVille exploratory study, reported by pv magazine in 2021. It is a suggestion, not a rule.
  • VERIFIED Used panels were resold at about 70% of the new-panel price in IRENA's 2016 research (IRENA and IEA-PVPS 2016, "Repair of PV panels (reuse)"). About two-thirds of replaced or prematurely failed modules can be repaired and reused, an expert estimate (Tsanakas et al. 2025, page 2).
  • VERIFIED IEA PVPS Task 13 (2026) judges the second-life PV market to be fragmented and underdeveloped (executive summary). It also states that it does not aim to give a comprehensive quantitative performance or reliability assessment of all repair technologies.
  • ILLUSTRATIVE Most default prices and costs in the tool are illustrative placeholders until you replace them.
  • ESTIMATED Route values are our calculation from your inputs. They move with those inputs, so read them as a comparison, not a forecast.

Material recovery

For recyclers, recovery operators, and owners of decommissioned crystalline-silicon fleets who need a material balance and its value · on request

Mass balance

What you provide

  • Rated power in W, or module area in m², with the mass per m² if you have it. Silver per module in grams, if you know it.
  • Module type. This service covers crystalline-silicon modules.
  • Your recovery rates and material prices, each marked as an assumption.

What you get

  • A mass balance per module, by material: glass, aluminium, silicon, polymers, copper and silver.
  • The recoverable value at your prices.
  • The share recovered, set against the EU WEEE targets. This is not a compliance test: the WEEE rate counts the weight that enters recovery facilities (Article 11(2)).

Verified and modelled

  • VERIFIED A typical crystalline-silicon module is about 76% glass, 10% polymers, 8% aluminium, 5% silicon and 1% copper by mass. Silver and other metals are less than 0.1% (IRENA and IEA-PVPS 2016, section 3.1). Designs vary: a laboratory test of Italian panels found 70% glass (Latunussa et al. 2016, Table 6).
  • VERIFIED Silver content is about 6 to 10 g per panel (IRENA and IEA-PVPS 2016, Box 22).
  • VERIFIED Mechanical separation of crystalline-silicon panels is reported to recover more than 85% of the glass and more than 85% of the aluminium, each as a share of panel mass (cumulative yield; IRENA and IEA-PVPS 2016, chapter 5). These are reported yields, not a promise for your process.
  • ESTIMATED The 95% silicon recovery is an assumption of one process model (Latunussa et al. 2016, section 3.4.3.7). Any recovery rate you enter is an assumption until you measure it.
  • VERIFIED The EU target applies to the whole WEEE category, not to each material. It is calculated against all separately collected WEEE of that category (Directive 2012/19/EU, Article 11(2)). A single-material yield is not the same test as the 85% and 80% targets.
  • ILLUSTRATIVE Material prices are placeholders until you set them.
