Energy Systems Group, Botswana

Reliable – Renewable

Energy Systems Group strives to be the leading energy management company in the SADC region, with the recent shortage in electricity due to increased consumption, Energy Systems Group thus provides alternative solutions to conventional electrical energy. Energy Systems Group supplies, installs and maintains solar water heating systems, photovoltaic (PV) products and systems, as well as mechanical equipment.



Energy Systems Group provides the world’s leading geyser brand: Solahart. Solahart geysers are specifically designed for areas with medium to high solar radiation such as Botswana. The Solahart geyser is equipped with the latest technology in solar water heating. They efficiently preserve stored hot water with excellent prevention of freezing in adverse weather conditions. It is the most effective and trouble-free system available today. With your Solahart system, you can lower your energy bills, save money and also help preserve natural resources by using free energy from the sun and thus reducing greenhouse gas emissions into the atmosphere (up to 4.5 tonnes per annum per system).


Solahart water heaters come in different sizes: 180L and 300L indirect type systems. We also accommodate various customer requirements, with other sizes available being the 150L and 440L systems and are available on request. Huge returns can be achieved for hotel and lodge applications by using Solahart hot water systems. In some instances, as little as 3 years payback can be achieved.


Energy Systems Group prides itself in being the market leader in renewable energy in Botswana. Solahart geysers can be seen in various parts of the country. It is important to note that a variety of big companies in Botswana have adopted the use of Solahart geysers, amongst them the University of Botswana, Debswana and Diamond Trading Company.




The primary strategy use of PV as the electrical power source for a residence is reducing the need for conventional electricity. Today the PV industry is experiencing rapid growth as people around the world turn to cleaner alternative technologies, like photovoltaic, to supply the energy needs that rapidly depleting fossil fuels will not be able to meet. As energy demand prices continue to climb, many home owners are looking for cost saving solutions for their energy demands.


PV installations can operate for many years with little maintenance after the initial set-up, so after the initial capital cost of building any solar plant, operating costs are extremely low compared to existing conventional power technologies. Conservation should always be the first step when looking into alternative energy systems for home use.


Even though they are undeniably expensive, photovoltaic solutions offer many benefits over the long term. Combined with conservation measures, solar power can provide energy needed for many households. Small PV systems also provide cost effective power supply in locations where it is expensive and impossible to send electricity through conventional power lines. PV also offers minimal service and maintenance costs.



This involves powering a residence using solar energy. These systems would normally comprise of solar panels, batteries, charge controller and power inverter to power small loads e.g. lights, fans, TVs, computers, fridges and other selected electrical appliances. Energy Systems Group also provides power back-up solutions that are used to power household loads during power cuts.


PV solar water pumping is a perfect solution for farmers and the agricultural industry. It is significant to note that solar water pumping uses natural sunlight making it reliable and consistent in the supply of water. Solar water pumping comprises of a standard SQF solar pump, a pump switch, solar panels and the necessary fittings and accessories.
