Solar Irrigation

The output of a solar pumping system is very dependent on good irrigation system design derived from accurate site and demand data. It is therefore essential that accurate assumptions are made regarding irrigation water demand/pattern of use and irrigation water availability including well yield and expected draw-down. Please contact Solar E. Technology to start your irrigation system design.

Solar Vehicle

…. the past few years have seen a dramatic rise in the popularity of alternate energy sources, 
particularly solar power. The technology which directly converts the sun's rays into electricity is proving 
to be one of the more commonly used 'green' energies in the transportation markets. As research into 
solar power continues to accelerate and designers are busy trying to challenge people’s ideas of how 
vehicles that uses it can look. Solar E Technology has developed first time in Bangladesh Solar School Van.

Solar E Technology currently doing research to develop multi-gear solar hybrid vehicle.   

Solar Mini Grid

Solar E Technology Off-Grid Solutions develops scalable system solutions for grid-independent electricity supply based on renewable energies. From electricity for buildings in remote regions far from the grid to supplying entire towns and islands: with Sunny Island inverters acting as grid and battery.  Another focus of development is decentralized, grid-tie storage solutions: as a decentralized, intermediate storage option, the Sunny Backup system ensures a failsafe, grid-quality electricity supply.

Our Solar Mini Grid system is built in clusters. Each cluster consists of a battery bank with its own dedicated inverter chargers associated with grid tie inverter. The clusters are then combined to deliver the required energy output. The cluster design avoids single points of failure; in the event that one cluster fails, only one sub-system will be affected and the Mini Grid will still be operational.

Solar Nano Grid 

Solar Nano-Grids

Villages and towns that are far from the utility grid can have their electricity needs met by autonomous Nano-grids which can integrate solar, and other renewable energy sources to create a robust and reliable local grid. For customers, this source of energy operates just as if they were connected to the national utility: they pay a monthly fee based on their consumption. Innovative technology is emerging that allows for the Nano-grid to be controlled by mobile-enabled meters. These meters allow customers to pay for energy via mobile-money platforms, receive statistics on their consumption and energy credit remaining on their mobile devices, and for developers to remotely monitor the real-time performance and usage of the power system. When structured correctly, Solar E Technology Nano-grid projects can present a sustainable model for community electrification, with operating and maintenance costs covered by revenue from the metered customers. The Solar Nano-grids also offer an attractive return on investment for the operator of the system.

Solar IPS

Get a Solar IPS

Do not pay 200% more bill for emergency power using normal IPS

Power supply interruption in countries like Bangladesh is very common and has been for many years. It is still uncertain how long before this basic social service will be available to an acceptable level, but it is certain that with increased economic activities and growing population energy resource crisis become more if not tackled now. Use of normal IPS during the power blackout such as load shedding makes it even worse because the energy grid has to supply more power after the load shedding is over and all normal IPSs start charging.

A normal IPS draws *160%-200% more energy through your meter than it delivers during blackout periods. In chain, it creates more power blackouts in the national grid, an increasing chaos for future energy security.

Climate change impact is also 200% more for the same power. So be sensible by installing a Solar IPS for your home, office or apartment for an energy and environment wise sustainable living future.

Solar IPS will ensure you have power in your home during power blackouts and saving you from significant electricity bills rise which happens with normal IPS.

Solar IPS can also reduce your normal electricity bill when size is bigger than just emergency load or you do not have to pay any bill if you chose a system designed to suite your total power consumption.

Suitable for: Town or rural area, homes, flats, offices, shops and industrial buildings.

Sustainability in Large Office Building, Hospital, Industrial Complex etc…


Environmentally Sustainable Design (ESD) is the key concept for sustainability. Taking sustainability approaches in large complex  environment we can create a new world life that is naturally balanced with given natural resources, such as water and energy and other environmentally significant material, reduce climate impact of use of these resources and provide an economically sustainable future operation.


Solar E.Technology can offer design and consulting services to achieve sustainability goal of commercial complex.  Few key concepts are outlined for consideration in the design of the complex.


 Sustainability focus areas are:

Minimize use of fossil fuel source of energy which comes in the form of electricity, gas supply or other, in the ways of


# Minimizing the first demand

# Maximizing energy efficiency

# Energy and water recovery and recycling

# Maximizing use and production of renewable energy.

# Minimize material and chemicals that are environmentally sensitive and have high energy, global warming and ozone depleting potential.

# Management and maintenance of systems and components to its best operating performance



In minimizing the first demand the design should include:

# High star rating buildings features

# Minimize artificial air conditioning including heating and cooling

# Use of natural cooling processes such as evaporative cooling, natural ventilation and green vegetation

# Use of natural lighting where possible but with heat filtration

# Maximize thermal insulation where appropriate, including synthetic materials and natural insulating barriers such as double glazing and shading. Green roofing where possible can reduce significant cooling load in buildings.

# The use of phase change thermal storage to transfer cooling and heating load to a uniform level.

# Minimize use of direct electric heating

# Optimize the heating and cooling set points for building envelope and hot water supply.

# Minimize water flow at the ablution, showers and basin taps. Bypass mixture of hot and cold water in warmer weather where possible

# Maximizing “containing” the heating or cooling load example – automatic door closer in conditioned space.


In maximising energy and water efficiency the design should secure:


# Energy efficient equipment for all areas

# LED lighting

# Lighting control with automated features

# Use of fans with energy efficient motors for air  circulation. Similarly for water circulation.

# Use of ceiling fans for indoor air movement to increase “effective comfort” level and use less artificial air cooling.
