Net Metering

Net Metering (NEM) is a billing process that credits solar energy system owners for the electricity they add to the grid. NEM allows utility customers, who generate electricity, to use the electricity anytime, instead of only when it is generated. This means that a home or business can generate power during the day from a solar panel system and get kWh (kilowatt-hours) credited to be used at night or any other time they may need it. Credits are totaled each month by the utility and credits generated in low usage months may be used in higher usage months.

Self-consumption and self-sufficiency

Solar panels do not work at night or in cloudy conditions, wind mills depend on wind conditions, power generators depend on oil supply.
Real time energy generation has to be stored to optimize domestic use with no rupture of energy and permanent control on the storage reserve level.
Storage capability must be durably reliable, eco friendly and ready to handle long short cut of power supply.

Why Lithium-Ion batteries for Self-consumption ?

Better Security

Greater energy density

Lithium-ion batteries have an energy density exceeding 150 Wh/kg. The energy density of a lead acid battery is about 20 to 30 Wh/kg.

Best performance

Lithium-Ion batteries support up to 5000 thousand charge cycles and discharge unlike conventional lead batteries (about 500 cycles).

Lithium-Ion batteries accept large flows of discharge (1C to 3C continuous and peak)

The discharge curve of a lithium-ion battery is nearly flat, which allows to obtain maximum power to the complete discharge.

Ease of storage

Lithium Ion batteries can be stored for long periods even if they are partially discharged unlike conventional batteries which need to be fully recharged regularly and frequently. The rate of self discharge of Lithium-ion battery is very low.

Better heat resistance

Lithium-ion batteries can withstand high ambient temperature (up to 60°C)

Minimal maintenance

Lithium-ion batteries do not need any maintenance

Better for the environment

Lithium-ion batteries contain no toxic heavy metals such as lead and cadmium

Better life

The lifespan of Lithium Iron Phosphate is far superior to Lead batteries even for deep discharge cycles (up to 20 years). Lifetime > 80% after 1800 cycles at 1/2C charge discharge
