Welcome to Aster Integral Private Ltd

World-wide, energy and water demands are growing more and more every day. The sustainable long-term supply using conventional solutions is a big challenge in today’s development forums.

Having built our business menu and reputation on the basis of this fundamental mission, and on the underlying principle fact that energy, water, information and housing are precious services driving human life in the modern economies.

We do provide intelligent engineering solutions and innovations to the Energy-Water problems for all clients ranging from individual households, institutions, municipalities NGOs and government agencies.

Aster Integral are consulting engineers and planners for a wide range of fields ranging from Renewable energy technologies, Water supply, Waste-Water and Municipal management technology, power generation, Electrical power systems, Power Back-up or UPS systems, and implementation of rural electrification programs.




We provide consulting and advisory services in the following fields:

ENERGY SERVICES

We offer services for feasibility studies, engineering design, procurement assistance, construction supervision and project management for the following fields:

  • Power generation from Solar-Photovoltaics (standalone and grid-connected power plants), Hydropower, Biomass (Wood residues and Biogasification), Wind energy
  • Power transmission and Distribution (132kV, 33kV, 11kV, 415/240V voltage standards)
  • Rural electrification including medium and low voltage networks as well as customer service connections
  • Hybrid and Standalone mini-grid power supply schemes for isolated remote communities
  • Network studies, Dynamic and Transient stability study for power networks and distributed power generation systems
  • Energy efficiency, Power audits and retrofits for power factor correction
  • Electrical installations for factories, commercial buildings and Residential houses
  • Power market studies, Energy economics and financial analysis
  • Solar-thermal technology for related applications like water heating for domestic, institutional and commercial applications
  • Power backup and Uni-interruptible Power Supply systems based on online technology for commercial buildings, institutions and        Residential houses

 
Example-1: Hydropower development and implementation

ASTER INTEGRAL was contracted by Emerging Power FZC/Z-One Holding of UAE to provide specialized services for the 15MWp grid-connected solar power plant, proposed at Bufulubi-Mayuge district.
Our staffs are assisting Newplan Limited in construction supervision of the 635kWp hybrid solar plant being implemented by KIS, at Kalangala-Bugala Island on lake Victoria.
We have also implemented several commercial and institutional solar-PV projects for hybrid power supply to Kolping offices in Hoima, Kampala-Kolping Hotel at Kampala; Nile Guest House in Njeru town council, together with a large number of institutions/schools in Mukono, Mityana, Gulu, Lira, and urban homes in Kiwatule, Naguru and Wakiso district.

 

 

WATER SERVICES

We offer services for feasibility studies, engineering design, procurement assistance, construction supervision and project management for the following fields:

  • Solar-water pumping, for water needs ranging between 1m3/day to over 300m3/day powering small DC pumps and large-three phase AC pumps with electric motors requiring over 30kW power.
  • Piped water supply schemes for small towns and rural growth centres
  • Back-up support for operation and maintenance as well as specialized training and capacity building for water scheme operators

 
Example-1: ERT-Water Project

Innovation products under promotion

“SELF-SUSTAINING RENEWABLE HOMESTM”

This is a concept in which the solar engineers at Aster-Integral have packaged sustainable energy-water supply solutions that relieve a home-owner in the urban or peri-urban areas from high un-fair utility bills. The technology saves a domestic home owner nearly 90% of all utility bills, and offers nearly 99% energy and water supply reliability at affordable one-time costs. Operation and maintenance of these facilities is almost zero cost, with no need for human operator, and very limited repairs.

The Concept once implemented ensures that the utility services for electricity (such as from UMEME) and water (such as from NWSC) only act as backup in cases when nature has dictated. Energy and water supply all depend on the abundant God-given solar energy (sunshine) and rain.

pic12

Energy supply: Solar-Panels are used to supply electricity/heat to the household fully integrated, and automated in hybrid with the Utility power supply. System is maintenance free and requires no human operator.

Water supply: Rain water is harvested and stored in surface or underground tank. The water is then pumped to an over head tank using a solar-powered pump. Energy to the pump is supplied by the same solar system that was installed originally. No need for a new system unless otherwise specified by the engineer. (See separate brochure for details)

 

SOLAR SUPPORTED DRIP IRRIGATION

Solar supported drip irrigation system for agri-business. Size of Solar system: 240Wp, delivering 6,000liters per day, enough to irrigate 3 acres of land.
