- Electricity consumptionAnnual kWh + monthly profile if available
- Target system sizee.g. 750 kWp (or leave to supplier sizing)
- Battery storagee.g. 500 kWh usable, or leave open
- Grid connectionExisting contracted power, voltage level, surplus export allowed?

Buyer checklist
Before you submit, check this.
- Recent electricity invoices (12 months ideally)
- Roof structural load capacity or structural drawings
- Site photos / drone imagery if available
- Single-line diagram or grid-connection details
- Preferred ownership model (CAPEX, PPA, leasing)
- Planned timeline & any permitting work already done
Total value, not list price
Solar offers are easy to mis-compare — different panel wattages, inverter brands, battery chemistries, warranty terms and EPC scopes hide real value. ProfiCircle normalises system size, expected annual production (kWh/kWp), equipment quality, warranty duration, installation scope, monitoring, maintenance and payback assumptions, so you compare total value over the system lifetime rather than sticker price per kWp.

FAQ
Solar PV & Energy Storage — questions buyers ask first.
- Can one RFQ cover both PV and battery storage?
- Yes. Most commercial projects combine rooftop PV with battery storage and grid-connection scope in a single brief. ProfiCircle routes each line to qualified suppliers and consolidates offers in one matrix.
- Do suppliers handle permitting and grid connection?
- Most EPC suppliers offer full design, permitting and grid-connection support. The scope is itemised in each offer so you can see who manages what — and at what cost.
- Can I compare CAPEX, PPA and leasing models in the same shortlist?
- Yes. Suppliers may quote across ownership models. Offers are normalised on annual production, total cost and net cash flow so financial comparison is direct.
- Which countries do solar suppliers cover?
- ProfiCircle covers selected European markets through its direct supplier network. For Romania, Bulgaria and Hungary, solar projects are handled through our partner network. Country coverage depends on system size and grid-connection requirements.
- What documentation should I expect from suppliers?
- Suppliers may be asked to provide applicable documentation depending on project country, system size and grid-connection requirements — typically CE conformity, PV and inverter certifications, battery safety documentation, electrical design, installer qualifications and warranty terms.
