What's inside
From your first bill import to a fully modelled solar ROI — every tool you need to make a confident energy decision.
Import your historical energy bills in seconds or enter them manually. Solviren keeps a clean record of every month's electricity and gas data so your analysis is always grounded in reality.
Get the numbers that matter at a glance. Four KPI cards surface your yearly averages so you always know where your energy spend stands without digging through tables.
Compare every year side by side in a single table. Trend indicators flag whether your consumption and costs are moving in the right direction.
Visualise your monthly electricity profile with interactive bar charts. Toggle between consumption and cost, and switch between individual years or the multi-year average.
The same powerful charting you get for electricity, applied to your gas bills. Spot seasonal heating peaks and track year-on-year efficiency gains.
Model a photovoltaic installation on your actual roof with scientific-grade accuracy. Pick your location on a map, set your panel orientation, and Solviren runs a real pvlib simulation to estimate annual production.
Find out exactly when a solar installation or heat pump pays for itself. Model costs, government incentives, and safety margins to get a realistic break-even timeline backed by your own consumption data.
