Click ＋ Add Expert to record the first energy professional.
Their name, qualifications and licence numbers appear on the report as the validator.
Optional. If the qualification behind the report belongs to a company (audit organisation, design office), record it here.
Its name, registered office, tax number and licence number appear on the report next to the signing expert.
Enter the details for the new location.
Select the value column in Excel, copy it, then paste here.
Link 2+ locations — their hourly consumption, production and feed-in are evaluated together.
A new location is created for the chosen year.
Owner tool. Create and manage customer accounts — subscription, package and access.
Orders from the website. Issue the invoice, and once it is paid, create the account from the order.
Double opt-in: only confirmed addresses may receive the newsletter. Unsubscribed rows are kept as a suppression list — that is the proof the request was honoured.
Registrations from tanul.siteenergy.hu. The week column is the lead score: whoever reached week 6 is a warmer prospect than someone who stopped at the assessment.
Contact e-mails filtered by package and status — ready to paste into the recipient field. Load the accounts above first (Accounts → ⟳).
Logged actions and errors of active and past accounts (up to 90 days). The log stores an anonymised IP and account id — not names or addresses. Load the accounts above first (Accounts → ⟳).
Applies to every account unless overridden individually.
Combined hourly energy balance of the member locations.
Owner tool. Generate an access key and send it to the user — it works on any device.
⚠ Client-side gating is a deterrent, not security — real accounts arrive with the server version.
Fill in the address and property information for this location.
The whole hourly analysis of this location runs on one year — the examination year. Pick one of the last three closed years. Every uploaded or generated data series must belong to this year: system_hourly_data always holds exactly this one year with 8760 hourly rows (Feb 29 is dropped in leap years).
Optional. Pick a tariff from the catalog to auto-fill the fields, or leave empty to keep the fixed prices above. These feed the shared price model.
Look up the GPS coordinates using the address fields above (via OpenStreetMap / Nominatim — same service as Python geopy), or drop a pin directly on the map for locations without an exact address.
Select a module to manage this location. Click the name to edit details.
Import 15-minute consumption data. Automatically converts to hourly values for energy calculations.
Manage PV systems — planned and installed. Configure tilt, tracking type, and peak power.
Manage energy storage systems — planned and installed. Configure capacity and power ratings.
Manage chimney systems. Configure flue gas temperature, volume flow, and diameter.
Define annual technological heat demand, its required temperature, and its distribution across months, weeks, and hours — or from an uploaded hourly pattern.
Define hot water consumption and its distribution across months, weeks, and hours of the day.
Define heating and cooling energy needs per building. Configure HVAC units, set-point temperatures, and performance coefficients.
Candidate PV to size. Set the max installable power plus mounting, tilt, and cost — the optimizer solves the best size.
Candidate storage to size. Set cost/kWh and maintenance — the optimizer solves capacity and C-value.
Recover heat from a chimney's flue gas to cover a Technological Heat or Hot Water demand. Link a chimney and a demand, set the heat-exchanger effectiveness.
Store heat to cover a Technological Heat or Hot Water demand. Choose a technology — water, PCM, sand, molten salt or brick — charged from surplus solar, off-peak power or a heat source. Sizes the store and estimates payback.
Replace an existing Hot Water, Heat, or Building demand with a heat pump. Link it to a demand and set its COP / EER.
Add an electric vehicle as a smart, shiftable load. Set battery, charger and driving; smart off-peak charging is valued against flat pricing.
Reduce a building's heating / cooling need (insulation, glazing). Link to a Building energy need and set the improved demand.
Solar collectors (flat-plate or evacuated-tube) preheat a Hot Water or Technological Heat demand. The covered heat offsets that demand's original fuel.
A gas / biogas engine that produces electricity and heat together. Electricity offsets import; the heat covers a linked demand. Nets out fuel cost and CO₂.
A small wind turbine. Set the rated power and capacity factor; self-consumed generation offsets import, the surplus is fed in.
Power-to-power storage: an electrolyzer makes H₂ from surplus / off-peak power, a fuel cell turns it back to electricity. Values the peak−off-peak arbitrage at the round-trip efficiency.
Read-only performance indicators from the calculated hourly data: self-sufficiency, specific yield, CO₂, heat-pump SPF, battery cycles and economics. Run the Energy Flow Calculation first.

Windows can be freely dragged and arranged.
Click ＋ Add Demand to define your first technological heat demand profile.
Set the annual kWh and distribute it across months, weekdays, or hours.
Click ＋ Add Demand to define your first hot water demand profile.
Enter daily or annual litres and distribute across months, weekdays, or hours.
This is the backbone of every calculation: it drives the energy-flow calculation, the optimizer and every result. Upload it first — then tell the app below what the series actually measures, because the two possible answers lead to very different results.
Supports .xlsx, .xls, and .csv · 15-minute intervals will be converted to hourly.

Not needed for the calculation — the T-curve above is what drives it. If your meter export also has the reactive series, upload them here and the report adds a reactive-energy chapter with a power-factor correction proposal. The two directions are stored separately, because the distributor bills them separately.
timestamp + kvarh · .xlsx, .xls, .csv
timestamp + kvarh · .xlsx, .xls, .csv
Monthly totals in kvarh. The two directions are shown separately, never netted — the distributor bills them separately, and a site can be inductive by day and capacitive at night.
Click ＋ Add Building to define a building's energy needs.

Click ＋ Add Recovery Unit to plan flue-gas heat recovery.
Link a chimney (the heat source) and a Technological Heat or Hot Water demand, then set the heat-exchanger effectiveness.
Click ＋ Add Heat Store to plan thermal storage.
Pick a storage technology and the demand it should cover, choose how it is charged, then size it and estimate payback.
Click ＋ Add EV to plan an electric vehicle.
Set the battery, charger and daily driving; smart off-peak charging is valued against flat pricing.
Click ＋ Add Building Envelope Upgrade to plan insulation / glazing improvements.

Pick a collector type and the Hot Water / Heat demand it preheats, then evaluate the saving and generate the hourly heat column.
Click ＋ Add CHP Unit to plan combined heat & power.
Set the electric power and efficiencies, link the heat to a demand, then evaluate the net saving and generate the hourly columns.
Click ＋ Add Turbine to plan a wind turbine.
Set the rated power and capacity factor; self-consumed generation offsets import, the surplus is fed in.
Click ＋ Add H₂ System to plan hydrogen storage.
Set the electrolyzer, fuel cell, storage and efficiencies; the peak−off-peak arbitrage is valued at the round-trip efficiency.
