Development of a unique design and a single-page web application for an online energy calculator. The service builds a monthly energy balance for a private house, a camper trailer, an apartment or a warehouse from real climate data - temperature, solar irradiance and wind speed for hundreds of locations worldwide.

The user adds the equipment being considered - solar panels, batteries, a heat pump, an air conditioner or a camper power station - and immediately sees how it changes the balance: installation cost, annual expenses, savings and the payback period in the local currency. The calculation is free, needs no sign-up, can be shared by a link or exported to PDF, and the interface is available in four languages.

An energy calculation usually means spreadsheets and tables of coefficients, so the main design task was to hide that complexity without hiding the numbers. The user starts by choosing the type of building and its location, and the application pulls in the climate data for that place on its own; everything else is entered in plain terms - floor area, insulation, the number of people living there, the appliances in use.

The monthly balance is shown as a chart where consumption and production sit side by side, so it is immediately visible in which months a solar installation covers the demand and when the house still depends on the grid. Every piece of equipment added to the plan changes the chart and the totals at once: installation cost, yearly expenses, savings and payback period. This turns the calculator into a tool for comparing options rather than a one-off estimate.

A finished calculation can be sent by link to a family member or an installer, or saved as a PDF for a meeting with a supplier.
