What is a net zero home / zero energy home? The answer depends on who is answering.
The United States office of Energy Efficiency & Renewable Energy defines it as “a zero energy building produces enough renewable energy to meet its own annual energy consumption requirements, thereby reducing the use of nonrenewable energy in the building sector”
Renewables are defines as Solar, Wind, Hydro and Biomass.
In Nigeria the most common source of renewable energy is solar.
Since 2016 we have been a Net zero facility. We have 2 inverters. A 5 kw grid tied inverter with 2250 watts in panels and a 5 kw smart hybrid battery inverter with 5840 watts. We have a 10 kwh lithium battery bank. No grid and no generator (we might change that in the future)
We run normal home appliances.
