Solvera, a Calis Group LLC product

Solar system design and quoting, built into Shopify.

Solvera is a Shopify app that lets shoppers design a complete solar system on a merchant's own storefront. They choose panels, racking, inverters, and balance-of-system parts from the real catalog while a bill of materials builds in real time, then request a quote or check out.

What Solvera Is

Solvera is a faster way to sell complete solar systems online. Instead of trading spreadsheets and email threads, a merchant installs one Shopify app and turns any page into a guided system designer. The solar engineering, compatibility, string sizing, panel to microinverter limits, and racking counts, runs underneath, so the merchant supplies the catalog and Solvera handles the rest.

It is made by Calis Group LLC and runs natively inside Shopify, so quotes and orders flow through the store a merchant already operates.

Who It Is For

Installers

Solo installers and shops that want online quoting without building it from scratch.

Distributors

High-volume sellers running large, multi-brand catalogs.

Resellers

Sellers who need compatible, complete systems rather than loose parts.

Sales teams

Reps who build and adjust quotes for B2B and assisted sales.

What It Does

Guided design on the storefront

Shoppers pick panels, racking, inverters, and balance-of-system from the catalog, with a running bill of materials as they go.

Solar engineering handled

Compatibility, string sizing, and quantities are calculated automatically, so merchants add products without wiring up the math.

Works across manufacturers

Panels, inverters, batteries, optimizers, racking, and BOS from different brands mix freely, and only compatible options are shown.

Editable without code

Merchants change wording, images, and questions directly on the storefront to match their brand.

Three ways to close

Each finished design can be emailed as a branded quote, shared as a link, or added to cart for checkout.

Built-in sales mode

Reps build and adjust quotes alongside customers, which suits distributors and B2B accounts.
