Solar Item Supply and Maintenance

You don't have to worry about storing any energy; the grid will usual be there to make sure all the loads can run when the user wants them.

OFF GRID SYSTEM

Off grid can be Stand alone power system or mini grids typically to provide a smaller community with electricity Off grid solar power also stores DC electricity in Battery.

Solar Based Irrigation

Solar Irrigation Solutions are very attractive alternative to diesel powered pumping and support sustainable agriculture.


Solar Irrigation Pump

Solar pump Irrigation is the application of controlled amounts of water to field for land preparation and helps to grow agricultural crops at needed intervals with Solar Pump. Pumping system comprises of the pump, motor, solar modules, control device, piping accessories etc.
DC electricity produces, when sunshine strikes on the solar panels.
DC electricity either drives a DC motor or is converted to AC by inverter and propels of AC motor.
AC/DC motor is coupled with a pumping element (centrifugal or helical rotor), which draws water from surface/submersible water source.
It is made MPPT controller enables the systems to lift water even in diffused sunlight (cloudy or foggy days).

Advantages

Renewable energy, no fossil fuel, no environmental hazard, clean energy, undoubtedly, fully Ecological
One liter diesel produces about 2.7 kg of CO2 whereas Solar pump emits zero emission and zero operational cost
Unpredictable diesel price leading to uncertainty in crop economics.
Seasonal crisis of fuel availability.
Frequently maintenance of diesel pump.
Solar irrigation pump reduces cost of irrigation and reduce diesel fuel imports.
Solar irrigation pump has a very handsome financial return with positive NPV, short Payback period.


Solar Irradiance

Solar Irradiance is the output of light energy from the entire disk of the sun which is measured at the Earth.
In Bangladesh, the average solar irradiance ranges from 215 w/m2 in the North-West/day and 235 w/m2 in the SouthWest/day.


Application of Solar Panels in Multipurpose Use

In harvest time, it is used in threshing and husking purpose.
By using off-grid inverter and battery, the power of the panel may be used in lighting and home appliances at night.
The power is used for charging of Easy Bike.
It is used for light trap to prevent insecticide.
By Grid Integration, the excess power may be added to the grid and can generate a surce of income.


Grid Integration of Existing Off-Grid Solar Irrigation Pumps

Grid Integration is a utility billing mechanism that offers a credit to farmers and business customers who are making excess electricity with their solar panel systems and sending it back to the grid.
With Grid Integration, the owner is only billed for the “net” energy used each month, that is, the difference between the energy produced by the solar power system and the energy consumed by the house over the monthly billing period.
For grid integration of individual Solar Irrigation Pump (SIP), a DC circuit breaker, an interlocking switch, an inverter and a unidirectional (Export) meter will be required. During off irrigation season when the SIP will not be operational, the PV array will only export electricity to the grid via the inverter.
