Indra's Energy+ Household
Net positive energy with day to day transportation for 5 years running
General Energy Use, Strategies and Systems
Energy Use:
All electric home. Natural gas completely disconnected for 5 years now. 2 EV charging stations - 1 level 2, 1 level 1
Energy Strategies:
Increase efficiency thorough reasonable retrofits. Electrify everything by eliminating natural gas appliances. Convert automobiles to EVs. Monitor energy usage for a year. Install net-metered solar system sized to cancel out all the used electricity over the year.

Indra's Energy+ Household
Renewables and Energy Balance
Renewable Energy Sources: Renewable energy is generated within the building footprint (e.g. solar PV on the roof)
Renewable Energy System Description & Details
40, 295 W Canadian solar mono-crystalline modules (CS6X-295M) meted with a Fronius 11.4 KW single phase inverter. The array faces 40% east, 40% west and 20% south. Half of the array is equipped with Tigo optimizers to optimize output.
