OUR PRODUCTS

Please find below some of our products to give a rough indication of what Sigma Tap can develop for you. Please keep in mind that products will be developed tailor-made. The biggest mistake in renewable energy is standardization or duplication. For every project many factors are different such as radiation, temperatures, minimum, maximum or peak loads etc. So please consult our engineers for your project solution. We like a challenge and can coöperate with you from the very beginning.

ON-GRID SYSTEMS

When a grid is available a well calculated on-grid system can help you to bring your energy bill down. Many countries or grid companies will not allow you to deliver power back to the grid and in those cases it is very important not to create an oversized installation. As the on-grid system usually does not need a battery bank back-up, the initial capital investment will be lower than in the case of off-grid systems or hybrid systems. Depending on your climate, we can integrate solar and wind generators to work together to have your renewable energy supply maximized 24 hours a day.

Suitable for

Most urban situations
Factories with grid connection
Places that run a mini or island grid
Solar fields to strengthen a weak grid

OFF-GRID SYSTEMS

Off-grid systems we develop for places where the grid is not available. The systems are used to guarantee suitable power supply to remote installations and houses. The system consists of solar panels and or wind turbines, a battery bank, battery chargers and also the integration of a generator set is possible. Optionally, we can add a lan / gsm module to monitor the installation from your or our installer’s office. This remote control together with the high-quality product makes maintenance easy and affordable.

Suitable for

Remote houses
Farms
Telecom stations
Gas / Oil / Water pumping stations

HYBRID SYSTEMS

A hybrid system is designed in cases where the grid is unreliable. Solar power when possible in combination with wind generator(s) can be installed together with a back-up generator. when solar and /or wind power is available the inverters will send it to your in-house grid. If the grid fails, the generator will come on automatically and run on low capacity to create your own grid and still use the free renewable energy available.

Suitable for

On grid solution for small wind turbines up to 1KW
Small on grid PV solar configurations
Combination of solar and wind turbines
Streetlights

FLEXIBLE HYBRID INVERTERS

For small PV solar in combination with a small wind turbine Sigma Tap produces a Flexible Hybrid inverter.

This system is a steel case with a slide-in solution for Inverter PCB`s developed by Sigma Tap for solar and wind. A full protection system safeguard the inverters against overload and will brake the wind turbine in case of heavy wind to protect damage by overspeed. The inverter PCBs can be programmed and adjusted to the circumstances where they are operated. For bigger projects, we can program them in the factory. This system has a proven track record as it is successfuly installed in many places around the world. Contact us for more information.

Suitable for

On grid solution for small wind turbines up to 1KW
Small on grid PV solar configurations
Combination of solar and wind turbines
Streetlights

CONCENTRATED SOLAR POWER

In cases where there is a high volume need for power, steam or drinking water, Sigma Tap can help you to develop a state of the art Concentrated Solar Power (CSP) plant. Our company developed a 7.5 MW plant with heliostats and 78 meter tower and in addition to that a drinking-water plant with bottling factory for 500.000 bottles a day in Africa. Our engineers can guide you also in the fields of parabolic through and Stirling systems. Please contact us to learn about the possibilities, the terms and conditions for this type of projects.

Suitable for

Power utility companies
Factories
Food processing industries
Mining companies
Tea estates

CONTAINER SYSTEMS FOR RENEWABLE ENERGY SOLUTIONS

Many special applications and systems need special attention. Security for the system and tresspassers. Protection against risk of theft or vandalism. Climate risks as heat, dust, humidity or rain and strong winds. We never can exclude all risks but together with you we try to make the best possible inventory and prepare the installation against such risks. Sigma Tap is specialist in preparing and installing the whole system in steel containers. We give the installer a quick approach at the site and the client a higher quallity product, produced under the best possible conditions.

CONTAINERS WITH REVERSE OSMOSIS DRINKING WATER SYSTEMS

Reverse osmosis is the ideal and proven method for producing clean water. Sigma Tap offers advice on the optimum size and configuration for your application. We can run these installations with renewable energy as you wish. Sigma Tap supplies reverse osmosis installations all over the world produced to the customer’s demand.

Reverse osmosis is a process driven by a pressure differential across two sides of semi-permable membrane. This membrane has the capacity of separating dissolved salts, heavy metals, and pesticides from the water.

Suitable for

Coastal areas
Remote areas around rivers
Hospitals
Schools
