Everything You Need To Know About Solar Power Costs
The pressure on the electricity grid in South Africa is enormous and many people are turning to alternative solutions to make up for the shortfall. Solar power is one of the most common solutions to our power challenge and clients find using a solar array calculator a good starting point.
Solar power is a clean, renewable source of energy that can help you save money on your electricity bill and reduce your carbon footprint. The most common questions people ask before investing in a solar power system is: How do I calculate solar panel sizes and wattage and how much will a system cost?
We’ve developed an online solar calculator that can help you estimate the size and cost of a renewable energy system tailored to your requirements. The solar requirement calculator gives you an idea of how much money you’ll save with a solar system for your home or business.
Our solar calculator is easy to use. All you have to do is enter information about your monthly electricity bill, how much you want to save, and how many hours you want your battery to run. The solar output calculator will then give you an estimate based on this information.

How the Solar Savings Calculator works
The Solar Savings Calculator is an online tool that helps you estimate the size, cost, and potential savings of a photovoltaic (PV) solar system for your home or business.
It considers several key factors, including:
- Your energy usage: The solar system sizing calculator uses your monthly electricity bill to determine the appropriate size and capacity of the solar system you need to offset a significant portion of your electricity bill.
- The cost of solar panels and equipment: The solar calculator online factors in the current cost of solar panels and associated equipment. This is particularly important because continuing advancements in solar power production have increased the adoption of solar power.
The combination of factors allow the Solar Savings Calculator to estimate the overall costs and potential savings that a solar system tailored to your specific circumstances provides.
The information from the solar panel wattage calculator can help you make informed decisions regarding the adoption of solar power while considering your energy usage, the cost of equipment, and the potential financial incentives available.
HOW TO USE THE SOLAR SAVINGS CALCULATOR
- Single-phase: This is the most common type of electrical service in homes. It uses two wires, one for the live wire and one for the neutral wire.
- Three-phase: This type of electrical service is used predominantly in commercial and industrial settings or larger homes. It uses four wires, one for each phase and a neutral wire.
Your electricity bill contains a lot of the information you need to complete the form, including, how much electricity you use each month.
This information is important for the solar calculator because it will help to determine the size of the PV solar system you need.
If you don’t have your current monthly electricity bill, you can estimate your usage by looking at past utility bills.
You can also conduct a home energy audit to get a more accurate calculation of your energy usage. Although you can conduct the audit yourself, South Africa has several companies with professional installers who can do it for you.
Information regarding the number of kilowatt-hours (kWh) is essential to the calculation.
- A kilowatt-hour (kWh) is a unit of energy that is equal to one kilowatt of power used for one hour.
- To convert your monthly electricity bill to kWh, divide the total cost of your bill by the price per kWh.
- The price per kWh is usually listed on your utility bill.
Our solar system calculator has a function that estimates the number of kilowatt-hours (kWh) used per month based on your electricity bill’s amount .
This feature of our solar solution calculator allows you to choose the percentage of your monthly bill you would like to save.
For example, if you enter 50%, the solar calculator will estimate the size of the solar system you’ll need to cut your monthly electricity bill in half.

The solar calculator provides estimates on five aspects that are crucial to the energy production of all solar systems.
For example, if you enter 24, the solar calculator will estimate the size of the system you need for 24 hours of battery backup.
Our solar system calculator has a function that estimates the number of kilowatt-hours (kWh) of battery storage required along with the hours of autonomy.
1) Cost: This is the total cost estimate based on the numbers generated for the different components.
2) Size of panel array: The solar calculator determines the number of solar PV panels required to meet your needs.
3) Battery bank capacity: This refers to the battery capacity needed to power your home for your desired hours of autonomy.
4) Payback period: This is the time it takes for your solar system to pay for itself; for example, it will take 25 years of solar power generation for the savings from your system to equal the total system cost.
5) Monthly estimated savings: This is the money that will come off your electricity bill every month averaged over a year.
