Not recently, solar-powered homes were a rarity. But with good publicity and the tax incentives schemes, solar panels became a popular sight. Investing in solar panels can decrease your carbon footprint by an average of 35,180 pounds of carbon annually! Did you know that this is the equivalent of planting 88 trees every year? Although installing photovoltaics may seem like a simple process, this is more complicated than you might think. Check out this how-to install solar panels to get you started on the process already today.

What is the purpose of this project? Installing solar panels. Although this may seem like an easy task, adding solar panels to your home is not as straightforward as simply choosing a solar cell and nailing it to the roof. Investing in solar panels starts with you - specifically, you have to choose the system that is right for you and then follow a few steps that will allow to transform your idea into reality. But how can you make such a decision? How will you know if this particular system is the best solution for you? Follow this guide, to learn what is the best way to go about installing solar panels and the process will turn out to be much more fun and easy!
Investing in solar panels will reduce your carbon footprint and save money on your electricity bill. Not only this - you can earn money by applying for various incentive schemes offered by local authorities or the Government. But this is "step 7". First, lets get to know how solar panels actually work.
How It Works:
Solar panels (PV, photovoltaics) collect sunlight and convert that into electrical power. Solar energy captured with the use of a thin semiconducting material, usually silicon, is sent to an inverter which converts this into electricity we can use in the house. Read more about photovoltaics here.
Who To Hire:
Installing solar panels is not as simple as it may seem - slapping some solar cells on the rooftop and making sure that the array will stay in one place. Solar installation needs a lot of technical knowledge, normal mortals are lacking, for example installing wiring. Proper panel placement and a few square centimeters on your roof are the key to build an efficient and reliable solar panel array. Therefore, it is best if this will be left for the pros. When hiring a solar technician, be sure to find a person who:
- uses panels manufactured in United Kingdom. This ensures that your warranty will be still protected even if the company will go bankrupt;
- offers a strong warranty. The inverter should have a warranty that covers at least 10 years and the panels themselves are typically covered for 20 to 25 years;
- can supply references from at least two recent customers;
- is a licensed technician and there are no major complaints about his work.
Before you will consider investing in solar panels, be sure to check if your roof is exposed to the direct sun during most of the day (usually between 10am and 2pm). This is a requirement for the system to work efficiently. Trees, tall buildings and even chimneys should not cast any shadows on your future solar array. This is important, as even if one solar cell stays in the shadow throughout the day, the efficiency of the entire array is jeopardized as the system is tightly connected.
The prices of solar panels has dropped by 60% since the beginning of 2011. On average, the price of an solar PV array costs £3,500 per kWp installed, however costs continue to come down. Remember that on GreenMatch.co.uk you can compare quotes and find the best installers, who will provide you with the best solutions.
With the UK Government's tariffs (for example Feed-in-Tariff) it is possible to get paid for the electricity you generate with your solar PV array. Most domestic solar installations are between 1.5kWp and 4kWp. For a typical 3kWp system you would have to pay up to £10,000. Below you can see an example of how a typical domestic installation size of 3kWp could earn through the incentives. Read more about incentives here.
Lease, Free, Buy or Finance:
Leasing solar panel installations has become a very popular practice lately, as this is a way to defray the up-front costs. Leasing will also cover your expenses for repairs and maintenance. However, only a permanent installation comes with tax advantages and most likely increase the value of the house. Note that if you are not comfortable with either the option, you can get solar panels for zero costs. Free solar panels is a common practice but you would be surprised why is it not the best solution to go about.
Number of Panels:
This depends entirely on two things: the amount of energy that you need to generate and the level of insulation. Remember to get a good overview of those two factors.
Going solar will most likely get the attention of your insurance company. Solar panel installations usually raise your homeowner’s insurance so you may expect a small increase in your insurance rates.
Typical Project Length:
Installing the actual solar panels on the roof is not a daunting process, so you may expect to have them up on your roof in a few days time. However, the whole process from purchase to the actual installation may last for up to a month.
No needed. In England, Scotland and Wales, you are not required to apply for a planning permission for most of the domestic solar panel installations. But you might want to read into this if you are living in Scotland within the conservation area of World Heritage Site.
