But remember, we are here to help you, so contact us if you are unsure about anything.

Grid Tie Solution – no power during loadshedding, but saves on your Eskom bill

  • No Energy Storage Required: Unlike off-grid solar power systems that require energy storage solutions like batteries, grid-tie setups do not need storage as they can rely on the grid as a virtual energy bank. When the renewable energy source is not generating enough power, the grid supplies the shortfall.

  • Electricity Grid Connection: A grid-tie solution, also known as a grid-tied system, refers to a type of renewable energy setup, such as solar PV systems or wind turbines, that is connected to the main electrical grid. This means the system can both generate electricity for on-site use and feed any excess power back into the grid.

  • Synchronization with Utility Grid: Grid-tie systems use inverters that synchronize the electricity generated by the renewable energy sources (e.g., solar panels) with the frequency and voltage of the utility grid. This ensures the power generated by the system is compatible with the electricity supplied by the utility company.
  • Net Metering or Feed-in Tariffs: With a grid-tie solution, when the renewable energy system generates more power than is currently being used on-site, the excess electricity is sent back into the grid. In some regions, this excess power can be credited or sold to the utility company through net metering programs or feed-in tariffs, providing potential financial benefits to the system owner.
  • Sustainable and Environmentally Friendly: Grid-tie solutions promote the use of renewable energy sources like solar and wind power, reducing reliance on fossil fuels and contributing to a cleaner and more sustainable energy mix. By harnessing renewable resources, grid-tie systems help reduce greenhouse gas emissions and mitigate the impact of climate change.

Off-Grid Solar Power Solutions – no connection to Eskom whatsoever, ideal for remote locations

  • Stand-Alone System: An off-grid solar energy solution is a stand-alone system that operates independently of the main electrical grid. It relies solely on solar panels to generate electricity, making it ideal for remote or isolated locations where grid connection is not feasible or cost-effective.

  • Battery Storage: Unlike grid-tied solar power systems that export excess electricity to the grid, off-grid solar setups require energy storage in batteries. The excess power generated during sunny periods is stored in batteries for use during times when the solar panels cannot produce enough energy, such as at night or on cloudy days.

  • Energy Independence: Off-grid solar energy solutions offer energy independence, allowing users to generate and store their electricity. This makes them less vulnerable to power outages and utility price fluctuations, providing a reliable and stable energy supply.
  • Sustainable and Environmentally Friendly: Off-grid solar systems utilize clean and renewable energy from the sun, reducing reliance on fossil fuels and lowering carbon emissions. They contribute to a greener and more sustainable energy ecosystem, promoting environmental conservation.
  • Customization and Scalability: Off-grid solar energy solutions can be tailored to meet specific energy needs. Users can design and scale their systems based on power consumption requirements, making them suitable for a wide range of applications, from small residential cabins to large-scale industrial operations in remote areas.

Hybrid Solar Power – energy independence for self-generation & storage of power, while connected to the grid

  • Increased Energy Independence and Resilience: By combining multiple energy sources and incorporating battery storage, hybrid solar solutions offer greater energy independence and resilience. Users can reduce reliance on the grid, decrease energy costs, and ensure continuous power supply even during grid outages.

  • Integration of Multiple Energy Sources: A hybrid solar energy solution combines solar PV panels with other energy sources, such as wind turbines, diesel generators, or the main electrical grid. This integration allows for a more reliable and flexible energy supply, especially in areas with variable weather conditions.
  • Battery Storage and Grid Connection: Hybrid systems include energy storage through batteries, enabling the storage of excess solar energy for later use during periods of low solar generation. Additionally, they can be connected to the grid, allowing users to import or export electricity when needed, providing extra stability and backup.
  • Load Management and Optimization: Hybrid systems often incorporate sophisticated load management and optimization technologies. These systems intelligently manage energy sources, prioritizing solar and battery usage when available, and switching to the grid or other sources when necessary, optimizing energy consumption and cost savings.
  • Environmental Benefits and Carbon Reduction: Hybrid solar energy solutions contribute to environmental sustainability by utilizing clean and renewable energy sources. The integration of solar power and other renewables helps reduce greenhouse gas emissions, promoting a greener and more eco-friendly energy generation approach.

Backup Power Solutions – usually battery-based systems for critical applications (security) powered mainly by the grid, but can also have solar components

  • Emergency Power Source: A backup energy solution provides an alternative power source during power outages or disruptions in the main electricity supply. It ensures critical appliances and systems continue to function, offering peace of mind during emergencies.

  • Standby Power Generation: Backup energy solutions often involve generators or battery systems that can be activated automatically or manually when the primary power source fails. These systems can provide power for varying durations, depending on the capacity and fuel/battery level.
  • Redundancy and Reliability: Having a backup energy solution adds redundancy to the power supply, enhancing the overall reliability of the electrical system. It minimizes downtime in critical situations and ensures essential operations can continue smoothly.
  • Versatility: Backup energy solutions come in various forms, including diesel, natural gas, propane generators, or battery-based systems. Users can choose the one that best fits their needs, considering factors like power requirements, fuel availability, and environmental considerations.
  • Critical Applications: Backup energy solutions are particularly important for critical applications such as hospitals, data centers, security systems, and communication networks. These applications require uninterrupted power supply to avoid potential hazards or data loss.

Bespoke Solar Power Solutions – custom designed to suit your goals, budget, consumption requirements and location

  • Tailored to Specific Needs: A custom-designed solar energy solution is specifically created to meet the unique energy needs and requirements of a particular project, location, or application. It takes into account factors such as energy consumption patterns, available space, budget, and energy goals.

  • Optimal System Sizing: Custom-designed solutions ensure the solar PV system’s size is precisely calculated to match the energy demands of the property or facility. This helps maximize energy generation and ensures efficient utilization of available resources.
  • Integration with Existing Infrastructure: The custom design considers the integration of solar panels, inverters, and other components with the existing electrical infrastructure, ensuring a seamless and efficient setup.
  • Advanced Technology and Components: Custom-designed solar solutions allow for the selection of high-quality and advanced technology components that best suit the specific requirements. This may include the latest solar panels, smart inverters, energy storage options, and monitoring systems.
  • Long-term Viability and Cost-effectiveness: By tailoring the solar energy solution to the site’s unique characteristics and energy demands, it ensures long-term viability and cost-effectiveness. The custom design aims to optimize energy production and provide a solid return on investment over the system’s lifetime.
