From customer survey to a clear proposal.

Solar Quote Studio is our web software for solar planning and quotations. It brings load assessment, preliminary equipment sizing, pricing and estimated CO₂ savings into one workspace.

01 · Assess

Understand the load

List appliances, their wattage and daily operating hours to calculate estimated energy demand.

02 · Plan

Prepare a system estimate

Review indicative inverter, battery and solar array sizes with the calculation assumptions visible.

03 · Quote

Share the proposal

Add your equipment and installation prices, then print a customer quote or save it as a PDF.

01 · Load survey

Customer appliances

Use the wattage on each appliance label and estimate how many hours it runs per day.

02 · Preliminary sizing

System estimate

Assumes all listed loads may run together, 25% inverter headroom, 80% usable battery capacity and 90% conversion efficiency. Solar array uses 4 peak sun hours and 75% system yield. Battery estimate covers one day of listed use.

A qualified installer must confirm startup surge, peak sun hours, roof space, shading, cable sizing, protection and equipment ratings before installation.

03 · Quote details

Before you begin

Using Solar Quote Studio

How do I try the demo?

Choose Load sample to see an illustrative appliance list. Replace it with the customer's actual appliance ratings and usage. Sample appliances represent a demonstration, not a completed customer project.

How is system capacity estimated?

The tool adds appliance watts × quantity to estimate connected load, then adds 25% inverter headroom. Daily energy is watts × quantity × operating hours. Battery nameplate capacity divides daily energy by 80% usable capacity and 90% conversion efficiency. The panel estimate divides daily energy by 4 peak sun hours and a 75% system yield. These fixed assumptions are starting points for an installer assessment.

How do I use the CO₂ estimate?

Enter the monthly electricity the solar system is expected to replace and the documented kg CO₂ per kWh for that source. Include the source and year in the reference field. Monthly savings equal displaced kWh × emission factor. Annual savings assume the same displacement for 12 months.

Where are customer details stored?

Save draft stores one project in this browser on this device. A new save replaces that draft. Restore saved draft retrieves it. Customer details entered here are not sent to our team by this calculator. Printed and downloaded quotes are stored wherever you save them.

Can I use the quote to order equipment?

The quote is a preliminary proposal. Prices are entered by the installer. Confirm site conditions, final equipment specifications, applicable taxes and project terms before placing an order.
