Solar panels are a great way to reduce your carbon footprint and energy bills while generating clean energy for your home or business. However, choosing the right solar panels can be quite daunting, especially for those who are just starting out. In this article, we will provide you with all the information you need to choose the right solar panels for your needs in the United Kingdom.
Firstly, it’s important to determine your energy needs. You need to know how much electricity you use on a daily, weekly, and monthly basis. This will help you determine how many solar panels you need to install. You can get this information from your energy bill or by using an online energy calculator.
The next thing you need to consider is the size of your roof. Solar panels come in different sizes, and you need to make sure that you have enough roof space to accommodate the number of panels you need. A typical solar panel is around 1.6 meters by 1 meter, and you will need around 10 square meters of roof space for a 1 kW solar system.
The orientation and tilt of your roof are also important factors to consider. Ideally, your roof should face south to get the most sunlight throughout the day. However, if your roof faces east or west, you can still install solar panels, but you may need more panels to generate the same amount of energy. The tilt of your roof is also important. A tilt of around 30 degrees is ideal for solar panels in the UK.
Another important factor to consider is the efficiency of the solar panels. The efficiency of a solar panel is the amount of sunlight it can convert into electricity. The higher the efficiency, the more electricity the solar panels can generate. In the UK, solar panels typically have an efficiency rating of between 15% and 20%.
The type of solar panel you choose is also important. There are two main types of solar panels: monocrystalline and polycrystalline. Monocrystalline solar panels are more efficient and more expensive than polycrystalline solar panels. However, polycrystalline solar panels are more affordable and have a shorter payback period.
Finally, you need to consider the cost of the solar panels. The cost of solar panels varies depending on the size, efficiency, and type of solar panel you choose. You also need to factor in the cost of installation, which can vary depending on the complexity of the installation.
In the UK, the cost of a 4 kW solar system can range from £5,000 to £8,000, including installation. However, the cost of solar panels has been decreasing over the years, and there are also government incentives that can help reduce the cost of installation.
The UK government offers a scheme called the Feed-in Tariff (FIT) that pays homeowners for the electricity they generate through their solar panels. The FIT scheme pays homeowners for every kilowatt-hour (kWh) of electricity they generate, regardless of whether they use it or not. The current FIT rate is 4.07p per kWh, and the scheme is set to end in March 2019.
In conclusion, choosing the right solar panels for your needs in the UK requires careful consideration of your energy needs, roof size and orientation, solar panel efficiency, type, and cost. By taking these factors into account, you can choose the right solar panels that will help you reduce your carbon footprint, save money on your energy bills, and generate clean energy for your home or business.
