An assessment from your invoice and data
Send your electricity invoice and interval data. Within three working days you have a technical and economic assessment of solar PV and battery storage for your supply point. Free, as a first step.
An assessment as the first step: what matters is not annual consumption but when you consume. The assessment shows it on your numbers, not on averages.

What the assessment contains
- 15-minute load profilewhen you draw power, how high the peaks are, how much PV output you would use
- Reserved capacity and tariffwhat you pay for capacity and peaks and what a battery will do about it
- PV and battery designPV capacity, battery capacity and power, placement, connection to the distribution grid
- Economicsinvestment, savings, payback from your electricity prices, no guarantees
- Subsidy eligibilitywhich calls are open and how the battery would be sized for them
What we need
- Electricity invoicethe latest invoice with the breakdown of distribution and reserved capacity
- Interval data15-minute data from the distribution system operator for 12 months, CSV or XLSX
- A few lines about your operationchanges in consumption, plans, roof, existing PV or transformer station
The assessment is prepared by the team that then designs and builds the project. Details of the solutions are on the pages Solar PV for businesses, Battery storage and Subsidies. Businesses and municipalities: obchod@energovision.sk.
Questions we get asked
1Where do I get interval data?
From your distribution system operator (ZSD, SSD or VSD) via its customer portal or on request; some suppliers send it on request. If you do not have it, send your invoices and we will request the data under a power of attorney.
2How much does the assessment cost?
Nothing. It is the first step of every project we do; if you choose a different contractor, you keep the assessment.
3What is in the assessment?
The 15-minute load profile, reserved capacity and peaks, distribution tariff, proposed PV capacity and battery capacity, economics with payback from your prices, eligibility for current subsidy calls and the recommended next step.
4How long does it take?
Within three working days of receiving the invoice and data. For more complex supply points we will get in touch with questions sooner.
