What are 2kW Solar Panels?
When you think of solar panels, you think of gigantic panels installed on your rooftops. However, a small, compact 2kW panel is good enough to power a small house with 1-3 people.
The basic framework of a 2kW solar panel system remains the same as that of a conventional system. Every system consists of a number of solar panels. These solar cells can be grouped to gather light and generate useable electricity.
Here’s where the difference comes in. The output rate of 2kW solar panel systems differs from that of other, bigger systems. The electricity generated per year by these solar panel systems is around 1.88kW.
Cost of a 2kW Solar Panel Setup
A regular 2kW system requires 14m2 of roof area. This brings in a cost of around £3,250. However, you would have to consult with a professional installer to get the final cost for your system.
The installer will factor the area of your rooftop and possible hindrances into consideration. It is safe to keep somewhere around £4,000 aside for a 2kW Solar Panel as a rough figure.
Getting Optimum Returns From Your Solar Panels System
Even though the investment incurred in a 2kW system is much less than a conventional system, it is still a substantial amount. Therefore, you would want to notice some substantial returns for your investment. To ensure this, you need to ensure that your system installer is accredited by MCS.
An MCS accredited installed system will enable you to seek benefits through the FIT scheme. This scheme rewards you for the extra energy you sell back to the national circuit.
Here are a few facts that will help you better understand your returns on investment.
- The payback period of a 2kW solar panel system is 7.5 years. This is very short compared to other systems.
- You will be making consistent profit above your investment post the payback period.
- 2kW solar panel system installed by an MCS-certified supplier will earn you 4.11p per kWh of energy generated. You are also given an export tariff of 4.77p per kWh.
- Additionally, FIT guaranteed you around 4.11p/ kWh more on top of everything.
How To Maximise Efficiency of your 2kW Solar Panel System?
The performance of your solar panel system is heavily influenced by your geographical location and the angling of your roof. A professional installer would determine the best position for installing the system.
It is crucial to remember that restrictions like building shading over your roof and trees might affect your system’s performance. Keeping all these points in consideration, here are 5 ways to improve the efficiency of your solar panel system.
Buy The Most Efficient Solar Panel Model Available
Solar panels are made up of photovoltaic cells. These cells convert solar energy into electrical energy. However, a solar panel can not convert all the solar energy it receives into usable electrical energy.
Therefore, a solar panel system’s efficiency is the percentage of solar energy converted into electricity. Try to find the best solar panel system available in the market based on the material and structure of the model.
Look for Panels That Provide High Concentrated Photovoltaic Cells
The purpose of CPV is primarily to concentrate sunlight on highly efficient solar cells. A conventional solar panel peeks at around 21% efficiency. However, the cells provided in CPV panels can reach up to 43% efficiency.
However, this increased efficiency comes with a raised price. CPV panels cost around 4 times more than a traditional solar panel system. It would be best if you checked the quotes of different manufacturers to get yourself the best deal.
Don’t Install Your Panels in a Shaded Area
The sole input of a solar panel is sunlight, and shade blocks sunlight. Therefore, it is only logical to keep your system away from shaded areas.
The total energy efficiency can be reduced even if one solar cell is guarded against sunlight because it performs as a resistor. Two of the most common barriers that often shade solar panels include tall buildings and trees.
It is empirical to be judicious during the planning process and make sure that shade isn’t an impediment.
Resort To Only Expert Installers
If you think of saving installation costs by approaching a non-certified local installer, it might not be a good idea. If solar panels aren’t installed optimally, they won’t get proper sunlight and will produce less electricity.
Here are some of the factors you should stress while getting your system installed:
- Solar panels should be at an angle of 18 to 36 degrees to maximize sunlight exposure.
- Since the UK comes in the northern hemisphere, your solar panels ought to be oriented towards the south.
- The efficiency of solar panels can decrease as the temperature rises.
- During installation, a sufficient gap should be left between the solar panels and the roof.
It is best to invest in an expert installer and qualified electrician to get the maximum benefit out of your system with so many factors to consider.
Clean Your Solar Panels Regularly
Your system wouldn’t require much maintenance since there are no moving parts. However, the accumulated dust and grime over the surface of the panels can reduce the system’s efficiency. Therefore, it would be best to treat your solar panel system with regular cleaning.
There is no fixed number for how many times you should clean your solar panels in a year. Factors like the frequency of rain and the cost of one cleaning session can determine how often you’d want to clean your system.
In the course of one year, dust and dirt are expected to cause a decline of 5% in the total output. However, the reduction can go up to 20% in areas where rainfall is scarce. Therefore, cleaning your panel once every year is a pretty ideal thumb rule.
How To Get a 2kW Solar Panel System?
Now that you know everything there is to know about 2kW solar panel systems, it is time actually to get one for your house. You would be happy to know that you can install your system without much hassle in the UK.
There are several certified installers that you can approach. You can start the process while sitting in the comfort of your home.
To get started, you can follow these easy steps to get a quote for your solar panel installation.
Step 1: Go to the installer’s website and describe your requirement for the product by filling out a form.
Step 2: The installer will connect you with different manufacturers and suppliers, based on your demand and geographical location.
Step 3: You will receive quotes from multiple suppliers based on your requirements.
Step 4: Analyse all the quotes to select the most viable supplier and get the installation process underway.
The solar capacity in the UK has increased from 5,488 MW to 13,259 MW in the last five years. This shows how the country is taking giant leaps towards shifting to a renewable form of energy. Options like 2kW solar panel systems provide you with the opportunity of contributing to this movement right from your homes.
2kW solar panel systems provide you with sustained energy and open doors for intelligent saving and profit-making.
