Nelumbo

What Nelumbo does

Nelumbo (legal entity NELUMBO Energy, a.s.) is a privately held Czech joint-stock company founded in 2003 and headquartered in Prague, operating in the integrated renewable energy systems segment. The company designs, sells, and installs turnkey photovoltaic solutions for residential, commercial, and agricultural customers across the Czech Republic, bundling bi-facial monocrystalline solar panels (up to 540 Wp, PERC half-cell technology), LiFePO4 battery storage (modular, up to 10,000 charging cycles, ~20-year lifespan), low-start-voltage inverters, air-to-water heat pumps, EV charging stations, and the proprietary NELUMBO SUNRISE smart-home regulation system that optimizes self-consumption against production and pricing.

The business model combines one-time hardware-and-installation sales with recurring managed services. Residential packages are priced from approximately 185,200 CZK for a small PV+battery system to roughly 1,443,670 CZK for a full large-home system after Nová zelená úsporám subsidies, with payback periods of 6-11 years. A separate commercial SVR (Služby výkonové rovnováhy / power-balance services) line sells or rents grid-stabilization battery storage at the 100 kW to 1 MW scale, with hardware packages priced 1.6M-16.3M CZK (ex-VAT) and subscription rentals at 69,800-699,900 CZK annually under multi-year contracts. Customer acquisition runs through direct sales (website inquiry, phone, on-site technical visit, custom proposal) plus a partner network of electricians and installers across the Czech Republic.

Nelumbo reports nearly 50 MW of cumulative installed capacity under its brand, a base spanning family homes, apartment buildings (SVJ), commercial/industrial sites, and ground-mounted solar farms (most notably a 2.112 MWp plant near Most from 2008 and a 1.1 MWp plant in Hustopeče u Brna). The company is owner-operated, has not raised external funding, and is a member of the Solární asociace and CAFT (Cech akumulace a fotovoltaiky) industry associations. Distribution is exclusively domestic (Czech Republic).
