International Area

    We are all living among an emerging global market. Moreover, there are no fronteirs for information, knowledge and comunication.
    At SOLTEKenergias, Ltd. we take this globalization very seriously, wich make us feel the need to expand our knowledge and experience, out of our country.

    Portugal has a solid and remarked experience at renewable energy fields, and SOLTEKenergias, Ldt. was born almost at the beggining of this "renewables revolution". As so, we have grown sustainably and carefully, allways learning new technics and different ways to act.
    Our state of art and due to a competent scientific and engineering team, able us to develop projects from remote sites to urban places all over the world. Countries from Africa, and such as Brazil or Saudi Arabia are probably the aim for the implementation of solutions where there's no public electrical grid.

    We present below a sample of some solutions we have available as turnkey systems for remote area

cellcube

    cellcube is an emission-free and clean suply of energy system powered by CellStorm. Working in a different manner than conventional batteries, cellcube has a lifetime up to 20 years.
    cellcube principle is based on a vanadium redox flow reaction. This type of reaction doesen't lead to any damage due to a total discharge and a high number of cycles won't affect the lifetime.
    With this system you can have up to 100 kWh of available energy, or much more, depending on the scalability you need.
    It also brings a monitoring system wich allows you to prevent remotely any failure before it happens.
    With cellcube, you have a secure and an almost free maintenance power supply at all times.

sun2go

      sun2go is a trade mark from Meeco AG.
    sun2go is a photovoltaic (PV)-based portable power supply comprised of a collapsible PV module and a wheeled trolley containing a battery, inverter, and charge controller.
    sun2go was specialy designed to power small appliances as electronic devices (mobile phones, laptops, TV's) , cooking and kitchen (microwaves, coffe makers, refrigerators), medical and emergency devices, climate control (air fan, space heater), etc.
    With sun2go, you can have a total energy stored up to 1kWh, AC (230V/ 600W) or DC (12V/ 15A).
    sun2go takes you where no other system go!

sun2water

sun2water is an other trade mark from Meeco AG.
sun2water is basicaly an offgrid system for water treatment. It can use a wide range of water treatment technologies to address local water conditions and requirements:

Decarbonation
Reverse osmosis
Nano filtration
Ultra filtration (UF)
Micro filtration
Specific ion removal
Chlorination

sun2water is able to treat water with an average flow of 700 L/ h and comes with a collapsible water storage tank of 7000 L and stores treated water for 10 hours. The raw water should be pumped from a depth less than 5 meters.
This system is ideal for villages or places where pure water is not available or the costs are too high to be afforded. Furthermore, it may allows the local social and economical development.
