About Our Company LessWatts is a micro-integrator of renewable energy. With a 13% Eskom price increase looming and probably even more from municipalities, this customer decided to be ahead of the wave and do something about it. 90% of his daytime use can be saved with the possibility of expansion in the future. This system was designed to be able to provide emergency backup to crucial loads in the event of a power failure. Designed to provide both cost saving and partial battery backup during times of power outages. This system is designed to conserve energy for the customer. In the event that all the energy is not consumed internally, the remainder flows to the public grid. This site serves as a reference for a possible larger project. It demonstrates the capability of solar power to the customer in driving the control units for three pivot point irrigation systems. We integrated a grid-tie solar system with his existing pre-paid electricity connection. System integration is done in such a way that the system can be expanded in future either by adding generation capacity (more solar panels) or batteries for increased self consumption or both.
