How Hybrid Solar Systems Work
Hybrid solar systems combine solar generation, battery storage, and grid power into a single integrated solution. Energy is generated during the day, stored for later use, and used when needed, reducing reliance on the grid and improving overall efficiency.
- Reliable power during outages and unstable grid conditions
- Use solar energy during the day and stored energy at night
- Reduced reliance on grid electricity and rising tariffs
- Systems designed and sized for your specific energy needs
- Expandable with additional solar and battery capacity

Residential Solar Systems FAQs
-
What size solar system do I need for my home?
The right system size depends on your energy usage, available space, and whether you want backup, reduced grid reliance, or full off-grid capability. A proper assessment ensures the system is correctly sized for your needs.
-
Can a solar system power my entire home?
Yes. Depending on the system design and battery capacity, your solar system can power your entire home or selected essential loads.
-
Do I still use electricity from the grid?
Hybrid systems use the grid as support when needed, while off-grid systems operate independently. Backup systems rely on the grid but provide power during outages.
-
How long do solar batteries last?
High-quality lithium batteries are designed for long-term use and can last many years depending on usage patterns and system design.
-
What is the difference between high-frequency and low-frequency inverters?
Low-frequency inverters use transformer-based designs known for durability, stability, and long-term serviceability. High-frequency inverters are lighter and more cost-effective upfront, but often prioritise compact design over long-term robustness.
-
Can my system be upgraded in the future?
Yes. Our systems are modular, allowing you to expand solar generation and battery storage as your energy needs grow.

Why going green is the best option.
There are many benefits to ‘going green’, but here are just a few:
- The average solar system in South Africa will prevent between 1.75 – 2.05 tons of carbon dioxide going into the atmosphere per year.
- Electricity prices are forecast to surge by 93% over an 8-year period [source: Times Live].
- A solar system adds real capital value to your home.
- A solar system allows you the possibility of not having a power bill for the next 25-40 years. Solar systems last for 25 years with an 80% yield, though they have been known to perform for over 45 years.
- Your energy use and the size of your solar energy system will determine the actual savings. Systems start paying for themselves immediately and the savings on electricity costs increases each year as the cost of electricity rises. A typical return on investment is usually around 15-20%.
With a solar system installed in your home, you will also have energy security for years to come.

The main types of solar installations.
A solar system that connects the solar panel installation with the main electricity grid is known as a grid-tie solar system and, if legislation allows, you will be able to feed excess energy back into the grid through a special meter, and when legislation allows you will be financially rewarded.
An off-grid solar system is generally installed for remote properties where the cost of connecting to the main grid is prohibitive or not financially viable. The solar system charges a battery bank which in turn is used to power all your appliances and lights etc. A generator may be used as a backup to the battery system for added security, if so required.
A hybrid solar system combines the best of both worlds: the convenience of a grid connected system — including the ability to earn Feed-In tariff credits (legislation applicable) — with the extra peace of mind of a battery backup. This means that even during a power blackout, you still have electricity.
A backup system allows you to enjoy a continuous power supply when the grid fails. When the grid power is off, energy is supplied to your home from a battery and inverter system, enabling you to continue with your daily routine.

Factors to take into consideration when going solar.
The cost of your solar system depends on several factors, including your current energy usage, your available unshaded roof space, your utility’s (Eskom’s) metering policy and other factors.
Normally solar panels will be installed as discreetly as possible on your roof, but if you prefer, they can also be erected free-standing elsewhere on your property.
Solar panel orientation is dependent on the installations latitude. As a rule of thumb, maximum solar energy in South Africa is obtained by having the solar panels face north and tilted upwards at an angle of 30 to 35 degrees.
You will also need to consider your energy requirements – how much electricity do you use, when do you consume the most electricity and what appliances do you use regularly? These factors will help determine the type and size of the system you need.
Look for professionals who can offer you strong warranties, good after sales support and that have a proven track record. Specialized Solar Systems – an established and reliable brand that you can trust.
