This unique solar PV system was created to pump water by using the sun's energy. Coupled to an Yaskawa Variable Speed Drive (VSD) with a built in Maximum Power Point Tracker (MPPT), this system allows for the direct conversion of solar energy to control the pump. Having no utility connection on site, this sustainable solar powered pump is 100% off the grid.
A solar energy system was proposed for the Golden Arrow Training Centre in Philippi, Cape Town. With an aim to reduce the municipal electrical bill by utilising the available sun energy, the new solar system will supply the training centre with sustainable energy, reducing municipal demand and shaving load spikes. An initial 25.6kWp system was built in 2018 and a 25.92kWp extension was added in 2020, bringing the total system size to 51.52kWp.
A manufacturer and supplier of trailer and off-road caravans, our client is a high energy consumer. With the aim to offset their high energy needs, they opted for a renewable energy solution. We provided them a 70 kWp roof top solar system that ties them to the national utility grid. Receiving 95-100% of their energy from renewable energy resources now, our client not only saved on OPEX and reduced their carbon footprint, they are also able to feed back to the national energy grid.
This Johannesburg distribution centre required a solution to help them save on their monthly energy bill. With large refrigeration plants and as high consumers of energy, the site is able to benefit from solar. We designed and implemented a 136kWp rooftop grid-tied PV plant to meet their energy demands and reduce their electricity bills. The plant is providing the client with a 17% ROI, producing them approximately 25% of their daily consumption.
An office block situated in Pretoria, South Africa, the site required a renewable energy system to reduce grid consumption and carbon emissions during the daytime. N.S.E. provided a full EPC/development service implementing a complete grid-tied solar solution. The site now supplements +10% of it’s total demand through solar with an ongoing O&M contract ensuring continuous system performance and optimisation.
A luxury Lodge situated in the Okavango Delta, Botswana. The site required a completely off grid renewable energy system as there is no grid connectivity in the area. Primary purpose of the installation was to reduce generator diesel consumption and carbon emissions, as previously this site ran on generators only. The remote location adds to logistical challenges of maintaining constant diesel supply. N.S.E. provided a full EPC/development service implementing complete microgrid and solar thermal solutions. The project included Solar PV, generators, batteries, and two upgraded centralized solar thermal plants with reticulation. The site now supplements +85 % of its total demand through solar and solar thermal, with an ongoing O&M contract ensuring continuous system performance and optimization.

This site houses guests from the MSC Cruise liner route looping around South East Africa. This specific site is located on Inhaca Island, Mozambique. The site required a completely off grid renewable energy system as there is no grid connectivity on the island. Primary purpose of the installation was to refurbish an existing installation, and upgrade in line with the facilities expansion. Typically the installation also served purpose to reduce diesel consumption and carbon footprint. The remote location adds to logistical challenges of maintaining constant diesel supply over land and ocean. N.S.E. provided a full EPC/development service implementing a refurbished and upgraded microgrid solution. The project included Solar PV, generators, batteries, and AC reticulation. The site now supplements +95 % of its total demand through solar and solar thermal, with an ongoing O&M contract ensuring continuous system performance and optimization.
