Home Solar System Cost: Solar Panel Cost and Installation
The complete home solar system cost is not inexpensive as I’m sure you know.
But, in spite of the eye-watering solar panel cost and installation for the home, it’s an expense that will invariably make your life a lot easier.
And, the high cost of your home solar system will be offset by a reliable and cheaper electricity supply.
Furthermore, for Cape Town residents who have paid their solar panel cost and installation, the city of Cape Town will pay for their excess power fed into the local electricity grid from June 2023.
Solar Panel Cost and Installation: Is the Home Solar System Cost Worth the Investment?
Complete Breakdown Of the Solar Panel Cost and Installation For a 3-Bedroom House Installation
Here’s a breakdown of the solar cost and installation for a 3-bedroom house.
Solar Panels
You’ll need 10 to 15 solar panels, of 250 to 300 watts each.
These solar panel prices can range from R15,000 to R20,000 each.
There the total cost for the panels will range from R150,000 to R300,000.Inverter
You’ll also need a grid-tied inverter with a capacity of 2.5 to 4.5 kilowatts.
A high-quality sine-wave home inverter price can be anything from R10,000 to R20,000.
Mounting System
To mount the solar panels securely to the roof you’ll need a decent roof-mounted racking system.
The cost of a good mounting system can be anything from R10,000 to R20,000.
Wiring and Electrical Components
The wiring and components needed to connect the system will include connectors, breakers, and other electrical components.
This cost will range from R5,000 to R10,000.
Installation Costs
The cost of installing your solar system, including the labour, permits, and any necessary inspections will be from around R30,000 to R50,000.
Batteries
In order to store the energy produced during the day for use at night or when the sun is not shining, a battery bank and a charge controller is necessary.
High-quality lithium-ion solar battery prices range from R50,000 to R100,000.
The total home solar system cost is, therefore, anything from R250,000 to R450,000.
You should note, however, that these costs are subject to change and may vary depending on the specific location, the size and quality of the solar panels, and the difficulty in carrying out the installation.
Also, you should get multiple quotes from different solar suppliers and installers to compare prices before making a purchase.
Also, depending on where you live, you should check to see whether there are any financial incentives or subsidies available for going solar.
For instance, Cape Town city is planning to pay providers for their excess electricity from June 2023.
There is also talk of making solar panels and components zero-rated, in terms of VAT, which would also help reduce the solar panel cost and installation.
3kw Solar System Price South Africa
The 3kw solar system price in South Africa is considerably less than a full home solar system to power a 3-bedroom house as above.
However, it will also power considerably fewer appliances.
But the 3kw solar system price in South Africa makes this an attractive option for people, so here’s a breakdown of the costs involved.
A 3kW solar system would typically require 6 to 8 solar panels with a capacity of 250 to 300 watts each.
A smaller inverter and fewer electrical components would be required for this system, resulting in a significantly lower cost than a system designed to power a 3-bedroom house.
Solar Panels
The cost of 6 to 8 solar panels with a capacity of 250 to 300 watts each would typically range from R60,000 to R80,000.Inverter
The cost of a smaller inverter for a 3 kW solar system would typically range from R10,000 to R20,000.
Therefore the cost of a 3kW solar system would typically range from R70,000 to R150,000, including all components and installation.
You can see that this 3kW system is way cheaper than a full-blown solar system for a 3-bedroom house which could cost anything from R250,000 to R450,000.
What Can a 3kW Solar System Power
With a 3 kW solar system, you will be able to power a variety of appliances in a home, depending on factors such as the specific usage and consumption of the particular appliance.
But, generally, a 3 kW solar system will power the following appliances;
- Lights
A 3 kW solar system can power all the lights in an average-sized house, including ceiling lights, table lamps, and outdoor lighting. - Small appliances
It will also be able to power small appliances such as laptops, tablets, and smartphones, as well as various kitchen appliances like toasters and coffee makers. - Entertainment systems
Your TV and sound system can also be powered by this size solar system. - Home office equipment
You’ll also be able to use a computer, printer, and other office equipment. - Fridge/Freeze
A standard refrigerator/freezer would also be able to run on this size system.
Please note that this is a rough estimate, and the actual power consumption will depend on the specific appliances, their energy efficiency, and their actual usage.
Also, a 3 kW system may not be sufficient to power all appliances at the same time, especially if heavy electricity consumers such as air conditioners or electric ovens are in use.
You’ll be pleased to know that a 3 kW solar system with battery storage will allow you to use the power generated by the solar panels even during the night and during grid power outages.
