Double Power Generation System

"Double power generation" is an expression used to describe the combination of photovoltaic power generation systems and ENEFARM systems, which make it possible to produce electricity where it is used.

With double power generation, priority is placed on the use of electricity produced using ENEFARM, which is supplemented when necessary using electricity produced by photovoltaic power generation. When power use is low, all required electricity is supplied by ENEFARM, and power produced by photovoltaic power generation can be sold. For this reason, double power generation is friendly to both the family budget and the environment.

What Is Double Power Generation?

Double power generation is a next-generation eco-power system that combines a photovoltaic power generation system and ENEFARM, which produce electricity where it is used. Skillfully combining photovoltaic power generation, which cannot generate power at night or on rainy days, and ENEFARM, which uses automatic learning in generating power around the clock, realizes a new style of living that is friendly to the environment and the family budget.

  3. Electricity purchased from the grid

The distribution board arranges for power from ENEFARM to be used first, followed by power from photovoltaic power generation, according to the amount of power used in the home. Surplus power from photovoltaic power generation can be sold to the grid.

Double Power Generation Features

1. Environmental Conservation Effects

Since energy is used where it is produced, combining ENEFARM, which entails little energy loss from power generation, and a photovoltaic power generation system, which utilizes natural energy from sunlight, makes it possible to contribute to reducing CO2 emissions.

  • *3Assumptions: photovoltaic power generation system installed capacity of 4 kW and annual power generation volume of 4,000 KWh
  • *4Assumptions: CO2 emissions of 0.69kg-CO2/kWh for electric power and 0.04kg-CO2/kWh for the photovoltaic power generation system

2. Economy

Surplus power generated at home can be sold to the grid. Double power generation is highly economical since much of the electricity used at home is provided by ENEFARM and much of the power produced by the photovoltaic power generation system can be sold.

3. Greater Awareness of Energy Conservation and the Environment

Household energy production, use, and sale can be monitored on a special screen for double power generation systems. This makes contributing to society through energy conservation is a fun and rewarding activity the whole family can enjoy.
