Grid-tied Solar Power System

A ZEN Energy grid-tied residential solar system allows you to enjoy the benefits of free solar power while still retaining a connection to the main power grid.

A grid-tied solar power system connects your residential power to a set of solar panels on the roof of your home, providing free power while the sun is shining. During periods of lower power production or high demand, it switches to the utilities-backed power grid.

Grid-tied solar power systems provide all the benefits of solar as well as the consistency of a main power grid.

All ZEN grid-tied systems include high-performance LONGi mono-crystalline solar panels and the latest GoodWe grid-tied inverters.

This combination provides you with the highest efficiency grid-tied system available, built from market leading components, all at an incredibly cost-effective price

A typical grid-tied solar power system includes three parts: the photovoltaic solar panels on the roof, a rack that holds those panels, and a solar inverter that converts the solar power into something usable in your home.

Once installed, a grid-tied solar power system instantly begins producing electricity, powering all your home appliances, including the fridge, the television, the lights, even the boiler. Any existing electrical connection can be powered by the grid-tied solar energy system.

This solar power supplements your existing power grid connection, instantly reducing your demand and reliance on your utility company and cutting down on your overall electricity bills.

If the sun isn’t shining or you experience higher-than-expected demand, a grid-tied solar power system can also draw on the grid as usual, ensuring you always have a back-up source of power.

Grid-tied solar power systems are, generally, the most cost-effective and easy-to-install of the three main types of solar power grids, making them one of the most popular of the three main types of solar power systems.

Generally, residential solar power systems are measured in kilowatts (kW), which refers to the maximum amount of energy that a system can generate.

ZEN Energy grid-tied solar power systems range from 2.22kW through to 5.18kW, with the top end being the maximum likely required for any residential application.

Grid Tied Solar Systems

Solar Power to Your Home During the Day

Not quite ready to let go of the grid? We get it. Our Grid-Tied solar power systems power your home or business while staying connected to the main power grid. If your solar generation isn’t enough, the grid kicks in seamlessly – meaning you’ll never be without power (unless there is a power cut!). Vice versa, if your solar power system generates more electricity than you need, the excess goes back to the grid and you’ll receive a credit on your next power bill.

A grid-tied solar energy system has several benefits, including:

  1. Lower energy bills: By generating your own electricity, you can offset the amount of electricity you need to buy from the grid, resulting in lower energy bills.
  2. Environmental benefits: Solar energy is a clean and renewable source of energy that can help reduce your carbon footprint and reduce your impact on the environment.
  3. Return on investment: A grid-tied solar energy system can provide a return on investment over time, as the system can pay for itself through energy savings.
  4. Energy independence: With a grid-tied solar energy system, you have the potential to generate your own electricity, which can provide a level of energy independence.
  5. Net metering: Most grid-tied solar systems are eligible for net metering, which allows you to sell excess energy back to the grid and receive credits on your energy bill.
  6. Low maintenance: Grid-tied solar energy systems require very little maintenance, with most systems only requiring occasional cleaning and inspection.
  7. Increased property value: A grid-tied solar energy system can increase the value of your property, as potential buyers may be attracted to the idea of owning a home with lower energy bills and a reduced carbon footprint.

A well-maintained grid-tied solar energy system can last up to 25 years or more. The lifespan of the system largely depends on the quality of the components used, the maintenance and upkeep of the system, and the weather conditions in the area where the system is installed. Regular cleaning, inspection, and maintenance of the solar panels, inverters, and other components can help ensure that the system lasts as long as possible.

Grid-tied solar energy systems are relatively low-maintenance. The solar panels themselves require very little maintenance, with occasional cleaning to remove dirt and debris being the main requirement. The inverter and other components may need periodic maintenance or replacement, depending on their age and wear. It's a good idea to have a professional inspect and service your system every few years to ensure it's working at peak efficiency. Additionally, monitoring your system's performance and checking for any issues on a regular basis can help you catch and address any problems early on.

A grid-tied solar energy system alone will not work during a power outage. However, some grid-tied systems are equipped with battery backup systems or generators that can provide electricity to your home during an outage. In these cases, the solar panels can continue to generate electricity and charge the battery, which can be used to power critical appliances and lights until power is restored. It's important to note that the battery backup or generator system will come at an additional cost and may require maintenance to ensure it's working properly in case of an outage.

Yes, with a grid-tied solar energy system, you can still use electricity from the grid when your solar panels are not producing enough energy to meet your needs. When your solar panels produce excess energy, it is fed back into the grid and you receive credits on your electricity bill. This is known as net metering, and it allows you to use electricity from the grid when you need it and sell excess energy back to the grid when you don't.

Net metering is a billing system that allows homeowners with a grid-tied solar energy system to receive credits for any excess energy they produce and send back to the grid. Essentially, when your solar panels produce more energy than you need, the excess electricity is sent to the utility grid, and your meter runs backwards, effectively providing you with credits for that excess energy. Later, when your solar panels are not producing enough energy (e.g., at night or on cloudy days), you can draw electricity from the grid and use the credits you accumulated during sunny days. This way, you only pay for the net amount of electricity you used from the grid. Overall, net metering can be a great way to save money on your electricity bill and maximise the benefits of your grid-tied solar energy system.

A grid-tied solar energy system may be a good fit for you if you live in an area with reliable access to the electricity grid, have a relatively high electricity bill, and want to save money on your electricity costs. A grid-tied system allows you to generate your own electricity and feed any excess back into the grid, reducing your electricity bill and potentially earning you credits through net metering.

However, if you live in an area with frequent power outages or unreliable access to the grid, a grid-tied system may not be the best option for you. Additionally, if you have limited roof space or face shading issues, it may be difficult to install a large enough solar array to meet your electricity needs.

Overall, a grid-tied solar energy system can be a great investment for homeowners looking to reduce their carbon footprint and save money on their electricity costs, but it's important to a consult with a qualified solar energy installation company like ZEN Energy to help consider your individual circumstances and needs before making a decision.
