Installing solar panels in your home could be an attractive idea. You can get electricity for free whenever it is sunny, saving you money on energy as well as helping the environment, without having to consider it a lot more.
Experts agree that reducing the carbon emissions emitted by heating and powering the homes of our families, who generate 5 percent of the UK’s CO2, is vital in order for the country to achieve its goal of becoming net zero by 2050.
In a time where the cost of energy is rising and increasing numbers of us would like to do our part for the planet, installing solar panels to your home has never been more attractive. What are the advantages and disadvantages to installing solar panels economically and environmentally considering?
Consumers are becoming more conscious of the need to switch to ‘green’ or renewable energy sources. Recent research by Citizens Advice reveals that two-thirds of homeowners are considering improving their homes’ energy efficiency over the next 12 months. Meanwhile, according to a study conducted by NatWest 55 percent of homeowners reported that they are planning to implement eco-friendly changes to their homes in the coming decade.
Wind and solar are currently the cheapest methods to produce electricity, and unlike conventional forms of energy, they’ll never last forever. It’s not a surprise to find that installing solar panels to the roofs of houses is a common upgrade for homes, with over one million solar panels installed on homes all over the UK. They’re not cheap however in the long term they can help reduce the cost of electricity and also reduce your carbon footprint. In addition, you’ll also earn a fee for the additional energy you create.

How do solar panels function?
The solar electricity panel, commonly referred to in the field of photovoltaics (PV) can take sunlight and convert it to electricity, which is then used to power your home’s main power source. The solar PV panel is made up of numerous cells constructed of layers of semi-conducting materials which is typically silicon. When light hits the panel, an electric flow electricity is generated, which means you are able to produce your own renewable electricity.
The energy generated by your solar panels can use to charge all appliances you have within your house at moment the energy is produced. Any electricity surplus that isn’t used is sent to the grid for which you’ll get a payment.
If you’re looking into solar panel options, then you might find thermal solar panels. However, these are used only to warm water.
How much do solar panels cost?
This is contingent on your selection of panels. This, in turn will depend on the amount of electricity your home makes use of, the amount of area you have for your roof, and the amount you’re willing to invest.
The majority of the expense of solar panels results from the installation process, and the Energy Saving Trust (EST) suggests that you get quotes from three installers at a minimum.
The installation cost are shared with you if you already have scaffolding in place for roof repairs , or if you’re building a brand new home. Costs also depend on the type of panel you select, tiles, and if you choose to build-integrated panels or panels that rest on the roof. Panels that sit on top of the roof are the most affordable option, whereas tiles are the most costly for the same system.
Do solar panels help me save money?
The time it takes before your solar panels be able to pay for their own, and whether or not you are able to earn profit from them, will be contingent on the price of the solar PV system you have installed as well as the amount of energy generated by it is available to utilize, and the extent to which (and what) you receive a fee for excess electricity.
Typically, solar panels placed in the roofing of homes or buildings will not provide much returns within the initial 20 years or so as per Mike Childs, head of research for Friends of the Earth. “But there are massive environmental benefits, based on the location you live in and the amount of electricity you use” he states. “The average person produces 12.7 tons of carbon emissions per year, but with the installation of solar panels, about 1 ton of carbon can be saved each year, meaning there is a lot of potential.”
Do I have the potential to earn money from the electricity my solar panels produce?
If you own solar PV systems and produce more energy than you actually need the excess will be remitted to the grid of energy used by the nation. In the Smart Export Guarantee (SEG) that was announced at the beginning of January in 2020 electricity providers provide a payment for every unit of power that you transfer to grid. The previous feed-in tariff program was more generous, but was closed to new customers in March 2019.
If you’re selling power back to the grid of the nation You can choose the most competitive SEG rate available in addition to any contract with an energy company which powers your home.
SEG tariffs are either flexible or fixed. Fixed SEG tariff will be paid an agreed rate for every kWh that is exported over the duration of contract. The variable SEG tariff will alter prices according to market demand with the one condition being that the prices do not fall below zero.
Solar Energy UK has a useful league table that reveals which companies currently provide the lowest rates. Additionally, Ofgem publishes a list of SEG licensees annually and you can reach out to an energy provider directly for more information about the rates it offers.
How do you make the most out of the energy you produce?
To maximize the energy that you receive from the solar panels, you must be mindful of when you are using your appliances.
Elliot Clark says: “Saving appliances that are running, such as washers, dishwashers or even washing machines to use during the sunniest periods of the day can help you save money. It is also possible to purchase a solar diverter when you are in the process of buying a hot-water storage or thermal store, therefore any power generated that the property doesn’t use could be used to heat the water to use for heating or washing.”
“Hot water cylinders are most likely to be a popular option because they are frequently utilized with heat pumps and are a great way to store excess power as hot water will decrease the energy consumption for the heat pump.”
Batteries might be another option homeowners can store the excess electricity generated by solar panels for utilize at a later time, however there’s a long ways to go before technology allows this to be a feasible alternative. At present, these batteries are in the size of bookcases and cost a lot of money and their cost could exceed the advantages. They also can only keep energy for a specific duration of time — usually for a few weeks at minimum.
What are the drawbacks of solar panels?
The primary obstacle is the amount of the time required for a return on your investment, as well as the difficult task of calculating it ahead of time.
Installation costs can be costly, and the performance of solar panels could be affected by weather conditions – this is much more prevalent for the UK than other countries such as in the USA or Australia. There are a few roof types that are appropriate, and panels may appear ugly and take up plenty of space.
The manufacturing of solar panels is not environmentally friendly. Friends of the Earth points that the majority of solar panels are produced in China in a country where the manufacturing process is dependent on coal. They’re also costly and hard to move. This could be a problem if are planning to relocate.
In a significant report that is based on their own consumer complaints Citizens Advice has expressed concern regarding cold-calling and mis-selling by unprofessional solar panel companies. The report states that many customers have signed contract terms that they don’t understand, and that leave them in worse shape than when they first started.
