How to make an app for a solar panel installer

A rooftop solar job runs for weeks: survey, quote, advance, material, installation, electricity board paperwork and handover, then cleaning visits for years. An app shows where every project stands, what has been paid and which customers are due a visit, so nothing waits on someone's memory.

Who uses the app

The owner, the office person and the installation team. If the team updates stages from site on their own phones, connect a Supabase database so the office sees the same project. If only the owner tracks projects, the data can stay on one phone.

The screens a solar panel installer app needs

Enquiries: New leads with phone, town, monthly bill amount the customer told you and the survey date
Roof survey: Roof type, usable area, shade, sanctioned load and the system size suggested, with photos of the roof attached
Projects: Each project with its stage: quote, advance, material, installation, paperwork, handover, and the next step
Payments: Instalments agreed for each project, what has been received and what is still due
Material: Panels, inverters, structure and cable sent to each site, with serial numbers
Service visits: Installed customers, cleaning or check visits done and the next one due
Map: Pins for every installed rooftop, to plan service visits area by area

Features worth asking for

A project stage list so you can see every job stuck at paperwork or waiting for material
Scan the barcode on each panel and inverter to save its serial number (in the installed Android app)
A quote PDF with system size, equipment, structure, labour and the payment schedule
Payment reminders as a WhatsApp message ready to send for the next instalment
A reminder on your phone at a set time for each cleaning visit due, from the installed app
A handover PDF listing the equipment, serial numbers and warranty periods for the customer's file

Where the data lives

If only the owner uses the app, the data can stay on that phone. If the office and site team all update projects, connect your own Supabase database from the chat; add Razorpay if customers should pay instalments online, with the money going straight to you.

How to make it with AppCub, step by step

Decide what the app does. List the screens you need, for example: Enquiries, Roof survey, Projects, Payments, Material.
Describe it to AppCub. Paste the request below, changed to your own business and details.
Check the plan. AppCub shows the screens and features it will build. Change them in the chat until they are right; seeing the plan is free.
Try it on your phone. The app runs live next to the chat. Scan the QR code to install it, and ask for changes.
Share it. Share it as a web link, an APK file, or publish it on Google Play from your own developer account.

Copy this request, change the details to match your solar panel installer, and paste it into AppCub:

Make an app for my solar installation business, Suryodaya Solar Works in Nashik. Screens: enquiries, roof survey, projects, payments, material, service visits and a map. A project has stages: quote, advance, material, installation, paperwork, handover. The roof survey has roof type, area, shade, sanctioned load, suggested kW and roof photos. Payments are instalments against each project. Material lists panels and inverter with serial numbers; let me scan the barcodes. Make quote and handover PDFs. Service visits show who is due for cleaning, with a phone reminder. Yellow and dark green colours.

Tips for a solar panel installer app

Write down your project stages exactly as your team uses them today and give AppCub that list; the app should match how you work.
Start with projects and payments. Add material tracking once every new project is entered from the survey stage.
Keep quotes to equipment, work and payment terms. Leave savings and subsidy figures out of the PDF unless you have checked them for that customer.
Keep customers' electricity bill photos and ID documents in the app only if you need them, and use sign-in if more than one person can open it.
Try scanning panel barcodes on the installed app before a big site; it doesn't work in the web preview.

What it costs

Describing your app and seeing AppCub’s plan for it is free.
A new app usually takes 60 to 110 credits. Start with the 2-day trial for ₹99 (150 credits, enough for one app and a few changes) or the one-time App Pack for ₹499. Starter is ₹1,599 a month for 700 credits.
Google Play needs a paid plan (it includes the Play Store bundle and your app’s signing key) and your own Google Play developer account, a one-time US$25 fee to Google.
Work that fails or is rolled back costs no credits.

Good to know

AppCub doesn't connect to inverters, solar monitoring portals or meters, so the app can't show generation or alert you when a system stops. It doesn't file paperwork with the electricity board; it records which step each project has reached.
AppCub builds Android apps. You can also share the app as a web link that opens on any phone; for the iPhone App Store, AppCub’s team can do it for you.

Questions

Can the app show how much power a customer's system generates?

No. AppCub doesn't connect to inverters or monitoring portals. The app keeps the project, equipment and service records; generation is seen in the inverter's own app or display.

Can I track each project through the electricity board paperwork?

Yes. Ask for project stages, including paperwork steps you name, and a list of projects stuck at each stage with the date they reached it.

Can my team scan panel serial numbers on site?

Yes, in the installed Android app the phone camera scans barcodes. With a Supabase database connected, the office sees the serials as soon as they are saved.

Can the app handle payments in instalments?

Yes. Ask for a payment schedule per project, such as advance, on material delivery and on handover, with what is received and what is due.

Will the app remind me about cleaning visits?

The installed app can show a reminder on your phone at a time you set, which may arrive a few minutes late. A WhatsApp button then lets you message the customer.

Can customers see their project status in the app?

Yes, with a customer screen connected to your Supabase database and sign-in, so each customer sees only their own project. Many installers start with the team's app and add this later.
