22 Apr 2023

Solar power generation is not only an ideal loadshedding solution, but a great way to reduce your environmental impact and save on monthly energy costs. However, it’s crucial to understand a few fundamental facts regarding solar panels before making a purchase for your home. Here are 10 things regarding solar panels that you should know.

Types of Solar Panels

Thin-film, monocrystalline, and polycrystalline solar panels are the three main varieties of Solar Panels. Each variety has distinct benefits and drawbacks of its own. Find out more about the different types of solar panels here. Choosing the right type of solar panel can be a daunting task, but understanding the differences between each type can help you make an informed decision.

How Much Solar Power Do You Need to Run a House?

The amount of solar power you need to run your house depends on several factors, such as your electricity consumption, the size of your house, and your location. Use this guide to help you calculate how much solar power you need. The number of solar panels you have will determine how much energy you can produce.

Household Appliances Electricity Consumption

Knowing the electricity consumption of your household appliances is crucial in determining how much solar power you need. Check out this list of common household appliances and their electricity consumption. Home appliance energy consumption is measured in watts(W). Newer appliances tend to need less energy with technology increasing efficiencies. Look for an “A” rating label when purchasing any new appliance in order to save as much power as possible to reduce the amount of energy your PV system needs to produce.

Solar Panel Installation

Installing solar panels requires careful planning and consideration. You’ll need to decide on the location, angle, and orientation of your solar panels. Taking into consideration your location, roof condition and any potential installation restrictions imposed by complex or area governing bodies. It’s important to hire a professional to ensure that your solar panels are installed correctly and safely. Using an accredited installer will allow you to get a COC for the installation.

What Are Solar Panels Made Of?

Solar panels work by converting sunlight into electricity, making them a great solution for powering homes, businesses, and even entire cities and are made up of several components, including silicon, glass, and aluminium. The construction of the solar panels and the materials used are a determining factors for their efficiency.

Solar Panel Maintenance

Regular maintenance of your solar solution is important to ensure that your solar panels are functioning optimally. This includes cleaning the panels and monitoring their performance. Regular maintenance of your solar panels is key to ensuring they operate at their peak efficiency.

Solar Panel Lifespan

Solar panels have a long lifespan, but their efficiency decreases over time. Solar panel lifespan refers to the amount of time that a solar panel can produce electricity at a level that is considered useful. The lifespan of a solar panel depends on several factors, such as the quality of the panel and the conditions it’s exposed to. Understanding the life expectancy of the panels will aid you to calculate the ROI of your solar system and prepare for any potential maintenance or replacement expenditures.

Net Metering

Net metering is a billing arrangement that allows you to sell excess energy generated by your solar panels back to the grid. Many of South Africa’s largest towns are currently introducing net metering regulations to let individuals and companies profit from solar energy production that is in excess of their needs. With the implementation of tax incentives making the installation of a solar system even more attractive.

Upgrading or Replacing Solar Panels

Over time, solar panels may lose efficiency due to wear and tear, environmental factors, or technological advancements. In some cases, upgrading or replacing your solar panels can help you generate more energy and save money in the long run.

When considering an upgrade or replacement, it’s important to evaluate the cost and benefits. Factors to consider include the age of your current system, the condition of your panels, and the cost of new panels or upgrades.

If you’re upgrading, you may be able to keep some of your existing equipment, such as the inverter or mounting system. However, if you’re replacing your panels entirely, you may need to replace these components as well.
