Drag to estimate your solar need
The solar sizing slide bar is an intuitive tool designed to help you estimate the size of the solar power system needed to offset your monthly electricity bill. Simply slide the bar to the right until it matches your typical monthly electricity expenditure. The tool will then calculate the recommended solar capacity in kilowatts (kW) that should be installed on your roof in the form of photovoltaic (PV) panels. This calculation assumes a cost of R3.50 per unit of electricity and is based on an average of 5 hours of sunlight per day. Additionally, a 20% safety margin is incorporated into the result to account for potential inefficiencies and variations in solar energy production. This ensures that the suggested solar system size is sufficient to meet your energy needs and provide reliable off-grid power.
Tips:
-
Convert to Gas: By switching to gas for hot water, cooking, and heating, you could reduce your monthly energy bill by up to 40%, significantly lowering the size of the solar system you need.
-
Switch to Solar Pumps: Replacing traditional water pumps with solar-powered ones reduces energy consumption, eliminates the need for constant grid power, and further decreases your solar system demand.

Why Incorporate a Standby Generator with a Solar System?
A standby generator is a crucial component for ensuring energy security, particularly in off-grid solar solutions. While solar systems provide a sustainable and efficient source of electricity, they are reliant on consistent sunlight to charge batteries and meet energy demands. During periods of prolonged cloud cover, rainy seasons, or unexpected increases in energy usage, solar energy production may fall short. Here’s why integrating a standby generator is essential: Reliable Backup During Low Solar Production Even the best-designed off-grid systems can experience days when solar production is insufficient. A standby generator steps in during these times, ensuring your household or business remains powered without interruptions. This is especially critical for systems that support essential appliances like refrigerators, medical equipment, or water pumps. Battery Health and Longevity Solar batteries are a significant investment, and their longevity depends on proper maintenance, including avoiding deep discharges. A generator helps protect your batteries by providing power when energy demand exceeds stored capacity, reducing strain and extending battery lifespan. Handling Peak Loads In some instances, energy demands temporarily spike beyond what your solar and battery system can supply, such as during high-use events or when starting heavy equipment. Generators can handle these surges, preventing system overload and ensuring consistent power delivery. Fuel Flexibility and Cost Efficiency Modern generators are designed to be fuel-efficient and can run on diesel, petrol, or even gas, offering flexibility in operation. When solar energy is unavailable, the generator provides a cost-effective alternative to keep your system operational. Peace of Mind For fully off-grid setups, having a generator as part of your system eliminates the fear of being left without power. Whether for emergencies or routine use during low solar production, a generator ensures that you are never caught unprepared. Integration with Solar Systems Incorporating a standby generator into a solar system is seamless with modern inverter technology. Hybrid inverters can manage the switching between solar, battery, and generator power efficiently, ensuring smooth operation without user intervention. Conclusion While solar systems are a cornerstone of sustainable living, the inclusion of a standby generator adds an essential layer of reliability. It complements your system, ensuring uninterrupted power supply, protecting your investment, and enhancing overall system performance.

Gas
Cut costs, increase reliability, get Gas

Cooking with LP Gas
Cooking with LP gas is not only cost-effective but also incredibly reliable. Gas stoves provide instant heat, precise temperature control, and are unaffected by power outages. This ensures meal preparation continues uninterrupted, saving both time and energy. Paired with a solar system, LP gas reduces the strain on your inverter and batteries, allowing your solar energy to focus on other essential appliances.

Water Heating with LP Gas
LP gas geysers heat water on demand, meaning you only pay for the energy you use. They are faster and more efficient than electric geysers, providing hot water even during load-shedding. When used alongside a solar system, gas water heaters eliminate one of the largest energy drains, significantly improving the lifespan and efficiency of your solar setup.

Space Heating with LP Gas
LP gas heaters are a reliable and cost-effective solution for keeping warm in winter. They provide instant heat without waiting for an electric system to warm up. By using gas for heating, you reduce the load on your solar system, ensuring more battery power is available for lighting and other essential appliances during the colder months.
Tips:
-
Trusted Products: Deltool-recommended products are handpicked for quality and reliability, unlike generic off-the-shelf items. You get long-term performance and better support.
-
Safe Installation: Using a registered gas practitioner ensures your system meets all safety standards, reducing risks and keeping your warranty intact.

Solar Borehole Pumps
Solar-driven borehole pumps provide a reliable and cost-effective solution for accessing water in remote or off-grid locations. Powered by free solar energy, they reduce reliance on grid electricity or diesel, cutting operational costs significantly. These pumps operate during daylight hours, ensuring consistent water supply while requiring minimal maintenance. They’re an eco-friendly and sustainable choice for farms, smallholdings, or residential properties.

Solar Water Pressure Pumps
Solar water pressure pumps maintain consistent water flow and pressure for households or irrigation systems without the high electricity bills. By harnessing solar power, they work efficiently during the day, ideal for watering gardens, filling tanks, or supporting water systems. Using solar pressure pumps reduces grid dependence, enhances energy efficiency, and aligns with sustainable living goals.

Solar Pool Pumps
Solar-powered pool pumps keep your pool clean and healthy while slashing energy costs. These pumps use solar energy during peak sunlight hours, eliminating one of the biggest energy drains in households. They’re low maintenance, environmentally friendly, and a perfect fit for reducing electricity usage while keeping your pool crystal clear.

Electric Geyser Solar Conversions
Converting an electric geyser to run on solar power dramatically reduces energy consumption, as water heating accounts for a large portion of household electricity use. Solar conversions use the sun’s energy to heat water, lowering electricity bills and providing hot water even during power outages. It’s a cost-effective upgrade that improves energy independence and supports a sustainable lifestyle.
