A 3kw solar system is a great way to save money on your electricity bills. This also helps to protect the environment since it uses the sun's energy rather than coal, oil or gas. But it isn't cheap to install and requires careful planning.
Cost of 3kw solar systems uk
The quality of the panels and other components will determine the cost of a solar system of 3kw. For most systems, you will need at least 8 solar panels. The cost of a standard solar system is as low as PS4,500 or as high as PS11,000 for an expensive system.
Panels cost a few thousand dollars per kWp, and a single panel can vary between PS2,000 and PS2,700 depending on the manufacturer. This is a big difference from years ago when solar panels were more expensive and less efficient.
Select panels of high quality and performance. The panels will be more efficient and more productive over their lifetime.
Solar panels come in two varieties: monocrystalline and polycrystalline. The most efficient panels are polycrystalline, but are also more expensive.
Solar panels vary in their efficiency, but on average they are around 15%. A panel with higher efficiency costs more, but will save you money over time.
You should get a quote for solar panels from a specialist. They can tell you how many you will need, what they cost and if there are any additional options available. You can ask a few companies for quotes and then compare them to find the one that best suits your needs and budget.
You will need a roof area of at least 16 square metres or 170 sq. ft. for a 3kw solar panel. The more space that you have the better your system will perform and generate more electricity.
Inverters convert the energy generated by solar panels to a form that can be used in your home. These systems can be as simple as an inverter or sophisticated with solar storage and batteries.
Inverters also connect your home to the grid. This allows you to still receive power even if the sun isn't out or if your solar panels haven't been fully used.
You'll be able to export any excess energy you generated back to the grid and get credit for it. This means you can take advantage of government incentives, such as net metering and subsidies, while also saving money on your electricity bill.
How to use electricity at home
Installing a 3kw-solar system on a roof that faces south is required if you have an electric bill exceeding $450 per quarter. The amount you can use depends on your location, the time of year, and how oriented your solar panel is.
