Solar & BESS Sizing + Quotation
The one tool installers open before, during and after every solar or BESS job — sized to how real installers actually work, not how a spreadsheet imagines they do.
For: Solar engineers · EPC contractors · Electricians · Installers
What it does
- Size solar arrays, inverter capacity and LiFePO4 battery banks from real load profiles
- Switch between country packs so sizing rules, standards and defaults already match wherever the job is — no manual re-checking against assumptions built for a different market
- Build and reuse your own equipment library from the brands and suppliers you actually stock
- Generate itemised, branded client quotations on the spot, before you've even left the site
- Save project designs on the device, then export and import JSON files to move a project between devices or share it with a colleague
- Build a custom equipment catalogue with local pricing, specifications, and bulk CSV import and export
- A built-in user guide walks a new hire through every screen, so bringing on a junior technician doesn't cost a training day
- Interface and in-app documents are available in English, Spanish, Portuguese, and French
Who it's for
Installers who need one mobile tool for data collection, design and proposal generation on-site — no juggling a calculator, a spreadsheet and a quote template
Homeowners who want to confirm or estimate the true cost of a solar/BESS system before ever inviting a salesperson in
DIY enthusiasts planning their own installation who want a professional sizing method instead of guesswork
Frequently asked questions
What platform is the app available on?
Android, via Google Play. A homeowner-facing web version for instant quotes is also in beta — see Solar Design & Instant Quote.
Does it work outside Kenya?
Yes — it supports country packs so sizing rules, standards and defaults switch to match wherever the job is, not just Kenya.
Can my whole team use it, or is it one device only?
Saved projects and custom equipment are stored on the device. Export a project as JSON or equipment as CSV to move data between devices or share it with a colleague.
Is training needed to onboard a new technician?
A built-in user guide walks a new hire through every screen, and the app runs in two languages to fit the team you actually have on-site.
