1. Cost-Effectiveness A 3kW inverter is suitable for medium-sized residential solar installations, making it a cost-effective solution for many homeowners. This capacity is typically sufficient to cover the energy needs of a home, reducing dependence on grid power and lowering electricity bills.
The efficiency rating of a solar panel is a key aspect to consider alongside its dimensions. Higher efficiency panels can convert more sunlight into electricity within a smaller area. While standard panels may have an efficiency of around 15-20%, high-efficiency models, such as those using monocrystalline technology, can achieve 22% or higher. This means that for the same power output, a higher efficiency panel may require less roof space than a lower efficiency option.

4. Orientation and Angle The placement of solar panels in relation to the sun is crucial for optimizing power output. Panels should ideally be installed at an angle that allows them to absorb the most sunlight throughout the day. In the Northern Hemisphere, solar panels facing south generally receive the most direct sunlight. Tracking systems that adjust the panels’ angles to follow the sun can further enhance energy production.
One of the most notable benefits of bifacial solar panels is their ability to capture sunlight reflected from the ground. This capability is particularly advantageous in areas with high albedo surfaces, such as snow, sand, or reflective rooftops. According to recent studies, bifacial solar panels can generate 10% to 20% more energy compared to their monofacial counterparts, depending on the installation location and surrounding conditions. This increase in energy output means that fewer panels are needed to achieve the same level of energy production, ultimately reducing the overall cost of solar installations.
Once your solar panels are installed, you can start enjoying their benefits! You''ll be generating clean energy and reducing your energy bills. However, you'll still have to pay for any energy you consume that is not generated by your solar panels. It is recommended to program your appliances to operate during the daytime to make the most out of your system. Additionally, you may want to consider investing in battery storage or other smart devices that enable you to utilise your free energy effectively.
Generally, the more expensive the system, the more electricity it can generate — and therefore, the more savings it can bring. The table below shows the annual savings on your electricity bills per system size, how much you can earn through Smart Export Guarantee (SEG) payments, and ultimately, how long it can take to break even.
4. Check Local Regulations Before installation, it's important to verify local building codes and regulations regarding solar panel installations. Some areas may have specific guidelines related to the aesthetics of solar panels on historic buildings or neighborhoods.
