Evidence-led pre-feasibility research

Test a solar and storage scenario.

The model combines site inputs with NRCan annual resource data. A site study must confirm roof, electrical and utility conditions.

Direct answer

Enerwav screens declared Canadian solar and storage inputs, reports bounded ranges, and suppresses unsupported results. A site study must resolve physical, utility, tariff, tax, and operating conditions.

Use the screen to improve the next question.

The Explorer is an answer-first planning surface for a Canadian commercial site. It turns a small set of declared facts into a bounded solar and storage screen, then shows exactly which parts still need study. It is not a quote, design, production guarantee, tax opinion, tariff determination, or investment recommendation. A useful result is often a clear suppression: knowing that export value, peak savings, tax treatment, or backup autonomy cannot yet be supported prevents an early assumption from hardening into a procurement claim.

Start with a municipality, site type, annual or complete monthly electricity use, and at least one physical sizing bound. Usable area limits what can fit; a target capacity records an owner or procurement objective. If both are present, the lower applicable bound controls the screen. The resulting DC and AC capacities are planning values based on visible model assumptions. Structural loading, setbacks, access, shading, equipment layout, service capacity, protection, and utility approval remain study questions.

Annual energy value needs an export decision.

An import electricity value alone does not prove that every generated kilowatt-hour avoids that value. The Explorer therefore needs either a paired export share and export credit or an explicit confirmation that all modelled generation will be self-consumed. Without one of those paths, combined annual value, payback, and cash flow stay unavailable. This is a deliberate safeguard against assigning full retail value to exported energy. A later study should use time-aligned load and generation, the current tariff, fixed and variable charge treatment, and the utility's settlement rules.

Storage outputs separate power, energy, and value.

Storage power describes the maximum dispatch rate. Nameplate energy describes charged energy, while the Explorer applies the entered round-trip efficiency to show discharged energy. Runtime divides discharged energy by nameplate power. Per-cycle value subtracts the cost of the full charged energy from the value of discharged energy, so losses are not treated as free. Annual energy-shift value remains suppressed until charge and avoided rates, cycle count, interval load, interval solar, and dispatch evidence are all confirmed.

A peak-clipping output is only a zero-to-upper-bound screen. Demand-charge savings need the controlling billing determinant, interval length, ratchet, billed months, and evidence that dispatch can coincide with the relevant peak. Backup autonomy is not stated because critical loads, reserve policy, islanding equipment, starting currents, temperature, degradation, auxiliary consumption, and operating requirements need a separate resilience study.

Commercial tax and finance inputs remain bounded.

The commercial mode can screen the Clean Technology Investment Tax Credit only after the user declares claimant and property eligibility, labour treatment, acquisition date, available-for-use date, eligible basis, and assistance. The acquisition must fall within the reviewed program window and cannot follow available for use. Capital cost allowance uses its own property, acquisition, available-for-use, UCC-treatment, and tax-rate questions. These outputs are preliminary and should be reviewed by a qualified tax adviser using the current law and the taxpayer's facts.

Cash, debt, and PPA choices are recorded so a requirements brief can ask the right commercial questions. The Explorer does not invent interest rates, lender fees, security, PPA prices, escalation, buyout terms, accounting treatment, or tax ownership. Its cash-flow chart is a consistent 25-year planning view built from the visible project ranges and entered operating assumptions. It should not be read as a financing model.

Read evidence beside every result.

Each available or suppressed output carries a confidence label, evidence references, a human-readable method, and a limitation. Official sources support public rules or datasets; owner evidence supports Enerwav's declared modelling choices; calculated values trace to those inputs. Verification dates matter because tariffs, programs, and source availability change. Reopen the linked official document before relying on a rule, and do not use a dated project example as proof of current eligibility or performance.

Finish with a study brief, not a screenshot.

Once the screen is valid, the requirements-brief link carries only typed, non-personal inputs. It excludes names, contact details, street addresses, arbitrary tariff text, and calculated outputs. The brief recomputes the scenario, lists suppressed values, and gives engineering, utility, tax, legal, insurance, operations, and procurement reviewers a common question set. That durable handoff is more useful than treating a preliminary chart as the answer.
