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. The installation is not cheap and requires careful preparation.
Cost of 3kw Solar System in UK
The cost for a 3kw system is determined by the quality and quantity of the solar panels. For most systems, you will need at least 8 solar panels. A standard system can cost as little as PS4,500, while a high-end one could cost as much as PS11,000.
Panels range between PS2,000 - PS2,700 per kWp. This depends on the manufacturer. It's a huge difference compared to years ago, when solar panels were less efficient and more expensive.
You'll want to choose high-quality, well-performing panels. 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 cells vary in efficiency between brands. However, the average residential panel is 15%. It is more expensive to buy a panel that is more efficient than one that is less efficient, but the cost difference will be worth it in the long term.
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. Comparing quotes is a great way to determine the company that will best suit your needs.
You will need a roof area of at least 16 square metres or 170 sq. ft. for a 3kw solar panel. The more space you have, the better the system will work and the more electricity it can generate.
Inverters are needed to convert the power generated by the solar panels into a usable form for your household. These systems can be as simple as an inverter or sophisticated with solar storage and batteries.
An inverter also connects your home to the grid. It ensures your house can still receive energy, even if it's not sunny outside or if all of the energy you've generated hasn't been used.
The excess energy generated by you can be exported back to the grid, and you will receive credit. You can save money on your electric bill and take advantage of government incentives such as net-metering.
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.
