How solar installers work

A solar installer's job runs over weeks: an inquiry, a look at electricity bills and satellite imagery, a site survey of the roof and electrical panel, a system design and quote, any grid connection or permit paperwork, then a one- or two-day install with scaffolding, panels, inverter and often a battery. Spring and summer bring the most inquiries, and energy price rises cause sudden spikes. Installers juggle a quoting tool, spreadsheets, a shared calendar and supplier emails. Software helps by keeping each home's survey, design, paperwork and install date together.

What quote & estimate app for Solar Installers has to handle

  • Quotes should include system size, panel count, inverter model, battery options and estimated annual generation.
  • Several options, such as with and without battery, help customers compare.
  • Scaffolding, electrical upgrades and bird protection should be itemized as extras.
  • Assumptions behind generation or savings figures must be stated clearly.

A tip for solar installers

Always quote a version with and without a battery. Many customers hesitate at the full price but will commit to panels, then add storage later; giving both options keeps the sale moving and sets up future work.

A prompt to start from

Build a quote and estimate app for a solar installer. Keep a price list of services such as site surveys, panel installation, battery storage and maintenance with a default rate. Let me create a quote for a customer with customer name, address and system size, add line items with quantity, rate and discount, and see a total with tax. Give each quote a number and a shareable page where the customer can accept or decline it, and show all quotes in a list with status and value. Use a database and add a login for staff.

Questions

Can a solar quote include estimated savings?

Yes, if you enter the assumptions such as generation and electricity price. Label estimates as indicative and state the figures used.

Can a customer accept a quote online?

Yes. Each quote gets its own page with an accept and decline button, and the status updates in your list. Ask Mythex to email you when a quote is accepted.

Can an accepted quote become an invoice?

Ask for it in chat: Mythex adds a button that copies an accepted quote's line items into an invoice, so customers are billed exactly what they agreed to.

Do I need to know how to code?

No. You describe what you want in plain language and Mythex writes the code, shows a live preview, and lets you change things by chatting. The code editor and terminal are there if you ever want them.

Do I have to explain my business every time?

No. Mythex remembers who you are and how you work across every project, and follows the standing notes you set for a project, so you are not re-briefing it in each new chat. You can read, edit or switch all of it off.

How much does it cost?

There is a Free plan with daily credits, enough to build and publish a first version. Pro is $25/month and adds full code editing, GitHub export, custom domains, and credit top-ups.
