Our solar cost calculator is a great tool for getting a sense of how much solar costs and how much you can save by going solar. However, every calculator is limited by its assumptions and its results
Calculate solar panel energy output per square meter. Get accurate daily, monthly, and annual production estimates based on location, panel specs, and system losses.
The following table shows the prices per solar panel, per Wp and per kWh, the number of square meters that these panels occupy, and including installation, materials.
Solar panel cost and savings calculator showing how many solar panels your home needs and likely cost based on current solar system prices, savings & payback period.
To use a solar panel cost calculator, users must initially provide the data asked for by solar panel companies. This includes data such as location, the size of your house, the type of roof
All costs reported are represented two ways: Minimum Sustainable Price (MSP) and Modeled Market Price (MMP).

Empa Solar Energy Europe is a leading energy storage equipment manufacturer and integrator based in Poland, serving the European market. We specialize in C&I energy storage systems for factories and warehouses, industrial battery storage systems for heavy-duty applications, factory energy storage systems (ESS) to optimize production, commercial battery energy storage systems (BESS) for retail and offices, enterprise storage solutions for corporate campuses, industrial park energy storage for multi-tenant sites, commercial battery storage for peak shaving, industrial battery storage systems for backup power, and remote base station power solutions for telecom towers. Our portfolio also includes lithium-ion batteries, system-level battery management systems (BMS), energy conversion systems (PCS), energy storage battery system cabinets, communication cabinets for telecom and data centres, integrated PV-storage systems, distributed energy resources, deep discharge battery technology, and containerised BESS. As a full-service provider, we also offer modular battery racks, backup emergency power, and zero‑carbon microgrids. Our advanced lithium‑ion and sodium‑ion solutions ensure safety, scalability, and high performance for commercial, industrial, and utility projects across Europe.
Our modular energy storage portfolio ranges from compact lithium-ion batteries to 20ft/40ft mobile containers and outdoor all-in-one storage cabinets with IP54 protection. We are a leading energy storage equipment manufacturer, offering communication cabinets for 5G/telecom, server racks for data centers, and IP54 rated enclosures for harsh environments. Our stackable design allows flexible capacity expansion, while our grid-forming technology ensures stable off‑grid operation. Whether for remote base stations, off‑grid power systems, backup emergency power, integrated PV-storage or large zero‑carbon parks, our products feature advanced thermal management, deep discharge cycling, and compliance with European and international standards. We also provide professional energy storage system installation and after‑sales support across Europe.
