Frequently asked questions, answered

Start by selecting your region and entering your average electricity bill or consumption. The first result is preliminary. The final configuration and price are confirmed after the roof data, equipment and engineering conditions have been reviewed.

The preliminary sizing is based on your electricity consumption and solar-resource data. Professional mode can refine the estimate using the exact property location, roof area, orientation and tilt. Final sizing and technical compatibility are confirmed by an engineer.

Payback is calculated when sufficient solar-production and financial data are available. The calculator can use the standard residential tariff or an effective electricity rate supplied by you. The result is preliminary and does not model future tariff increases, panel degradation, financing, taxes or future maintenance costs.

The final price depends on system capacity, the selected panels and inverter, mounting hardware, roof conditions, protection and electrical components, optional battery storage and installation work. Website pricing is a preliminary guide, not a contractual offer.

Credit or leasing availability depends on current financial-partner offers and the project parameters. A YOURENERGY specialist can explain the available options and terms for your project.

Periodic inspections, monitoring checks and cleaning when needed help maintain efficient operation. The exact maintenance schedule depends on the equipment, installation conditions and local environment.

Warranty periods can differ between panels, inverters, batteries and installation work. The selected equipment comes with warranty terms confirmed by the manufacturer or supplier. Final warranty obligations are confirmed in the proposal and contract.

Contact the YOURENERGY team and provide the monitoring error or a description of the issue. Diagnosis comes first; further action depends on the cause, equipment warranty and the applicable service terms.

The exact document set depends on the property, system capacity and current grid requirements. A complete document package is not needed for the preliminary online calculation. During implementation, the engineer confirms the documents and process required for the specific project.

That depends on the property type, project and current requirements. Before implementation, a YOURENERGY engineer will verify the current requirements for the specific property.

The final grid-connection scheme and requirements depend on the project and current network conditions. The calculator provides a preliminary solar assessment and is not a grid-connection approval. Connection compatibility is confirmed during the engineering stage.

Yes. Battery storage can be included when the selected inverter, system architecture and project conditions are compatible. Professional Calculator allows you to request a storage or backup assessment.

Accurate battery sizing depends on which loads must be backed up, their power demand and the desired backup duration. Total monthly household consumption alone is not sufficient for precise battery sizing.

Not every solar system continues operating automatically during a grid outage. Backup operation requires a compatible inverter, battery and properly designed backup configuration. This capability must be planned during system design.

It is possible with many systems, but it depends on the inverter model, electrical architecture and compatibility of the future battery. If storage may be added later, it is best to account for that during the initial design.

Quick Calculator is designed for an initial estimate: select your region and enter an average bill or consumption. Professional mode uses the same calculation foundation but adds exact location, solar-resource data, roof parameters, more detailed consumption inputs and expanded results.

Professional Calculator refines the preliminary estimate with location, consumption and roof data, then presents expanded results.

1. 1

   Step 1 — Location

   Search for the address, select the correct result and confirm the property on the map. If needed, select the point directly on the map or enter coordinates. The calculator obtains reference solar-resource data for the selected location.

   Tip: choosing the correct address makes the preliminary estimate more useful.

2. 2

   Step 2 — Consumption

   Choose the input method for the information you have: average bill, average kWh consumption or a monthly consumption profile. If you know your effective AMD/kWh rate, it can be used for the financial calculation.

   Tip: actual kWh consumption is usually more useful than the bill amount alone.

3. 3

   Step 3 — Roof

   Outline the roof on the map or enter a measured roof section area. For a map outline, mark at least 3 points on the same roof. Confirm orientation, tilt and mounting method. Map-derived roof area is preliminary.

   Tip: a map outline does not replace physical measurement or a shading assessment.

4. 4

   Step 4 — Results

   Review the recommended system capacity, panel count, annual generation, consumption coverage, roof compatibility, preliminary equipment selection and, when available, financial estimates. From the results you can open Solar Passport, create the PDF report or send the calculation to an engineer.

   Tip: the result is preliminary; an engineer confirms final technical compatibility.

If actual kWh consumption is available, use it. If you only know the monthly bill amount, the calculator can derive a preliminary consumption estimate. Professional mode also supports a monthly profile. More accurate consumption data produces a more useful preliminary system sizing.

Choose the roof-outline method and mark at least 3 points around the same roof section. Adjust the points if needed and review the resulting area. The map outline provides a preliminary projected area and does not replace physical measurement, shading assessment or structural verification.

Results include preliminary recommended capacity, panel count, expected generation, consumption coverage, roof constraints, preliminary equipment selection, environmental indicators and financial estimates when data are available. They are not a final engineering design or contractual offer.

Solar Passport brings together the calculation inputs, results, data sources, preliminary equipment selection and modelling assumptions. It helps explain what the estimate is based on, but it does not replace a site survey, engineering design or commercial proposal.

Yes. Professional Calculator results provide a printable/PDF report containing a summary of the system, roof, generation, financial picture, data sources and major limitations.
