Why Solar Electricity?

Many homeowners are installing solar power systems to reduce their reliance on Eskom, lower their electricity bills and make their homes more environmentally-friendly. Most electricity in a home is used in the early mornings and evenings and not during the day when solar power production is at its maximum. For this reason, we recommend using an off-grid or hybrid system with lithium battery storage, to store solar power generated during the day and make use of all this stored energy to power your household lighting and appliances at night.

How It Works

Solar panels collect energy from the sun and convert it into electricity, which is sent to the inverter. The inverter is one of the most important components of a solar power system and has two very important functions. It takes the electricity from the solar panels and charges the batteries as well as converts the DC from the batteries and solar panels into 230V AC. The AC electricity is then fed into your home to power your lighting and household appliances. There is no need to change any of your lighting or appliances.

Any excess solar power that is not used during the day is used to charge your battery storage system. The battery storage system supplies power to your inverter at night or when there is insufficient solar power available to satisfy your power needs. The system uses an automatic changeover switch to ensure you still have power from Eskom on occasion, when there is not enough solar and battery power available. This way you are almost certain to have power available at all times, day and night.

Frequently Asked Questions

Can the system be installed in a house that has 3-phase electricity?

Connecting solar power to a 3-phase supply is entirely possible. Options include:

  1. Connecting your solar system to only one of your supply phases with a single-phase solar inverter.
  2. Connecting your system into all 3 phases of your supply with a single, 3-phase solar inverter.
  3. Connecting your system into all 3 phases with 3 separate single-phase inverters.

What are the warranty specifics?

Victron Products – 5 years
Canadian Solar Panels – 25-year linear power output warranty; 12-year enhanced product warranty on materials and workmanship
Pylontech Battery – 7years from date of installation, extended for 3 years by successfully registering the product with Pylontech

Does the system need to be serviced?

The system is service-free and is monitored remotely by NuPower on the Victron platform, which our clients also have access to.

How long does the installation take?

The system installation generally takes two days in total, weather permitting – one day for the system components and another for the electrical connections; most of the time concurrently, but it can also be spaced over two or three days.

The systems installation generally takes two days in total whether permitting. One day for the system components and another for electrical connections. Most of the time concurrently but can also be two or three days apart.

How long will the battery bank last?

This will depend on the discharge load on the battery and this, in turn, will be determined by what is connected to the battery.

  • 7kWh bank @90% discharge at a rate of 1kWh will last 6,3hrs
  • 7kWh bank @90% discharge at a rate of 2kWh will last 3,15hrs
  • 7kWh bank @90% discharge at a rate of 500Wh will last 12,6hrs

The battery is expected to last for 6000 cycles at an 80% discharge – this is roughly 16 years.

Will the system take me off the grid completely?

This will depend on the house and the kWh consumption of the house, but all our systems are modular and can be expanded on to become fully off-grid.

Can I upgrade the system at a later stage?

Yes, our system is fully modular and upgradable over time to suit your needs.

How much will I save/panel?

8 x 405W panels will, on average, generate 15Kwk/day, depending on the consumption of the home; assuming 25kWh/day, the saving will be the 15kWh/day, resulting in a 60% saving.

What can I run on the system?

The entire house will benefit from the system under normal conditions with no interruption from the grid. Once the grid fails, only lights and plug circuits will receive power from the system. Pumps, ovens, stoves, geyser elements and underfloor heating, for example, wil not have power during power failures.

Can I push power back into the grid?

In most cases this is not possible, as the infrastructure does not allow for it. It is however possible at some estates with specialised metering in place. The system is capable of feeding power back into the grid where possible.

What is the difference between Grid Tied and Hybrid systems?

Grid Tied

This system consists of two components: solar panels and a grid tied inverter. This system produces energy and feeds into the house to reduce the consumption. The inverter is tied to the grid and needs it; if the power fails the systems switches off. If system needs to be upgraded to hybrid, either the inverter will have to be changed or a hybrid inverter will need to be added to the system to accommodate for the battery bank.


This system consists of three components: solar panels, inverter and battery bank. This system produces energy and feeds into the house to reduce the consumption and recharge the discharged battery bank. In the event of a power failure, both the panels and the battery bank supply power during the day, while at night, only the battery bank. The hybrid inverter can only operate with the battery bank connected. With panels it is a hybrid system; without panels it is only a back-up system.
