If you’re looking to install some new solar panels in your home or property, then you’d probably want to know how it works. This is one of the most frequent questions asked by homeowners when it comes to solar panels and in this article we aim to give you a good insight on the operations of solar panels. Let’s have a look!

Generally, solar panels work by absorbing the energy of the sun and then converting it into electricity. It functions by allowing photons from the rays of the sun release the electrons free from atoms within the photovoltaic or solar cells in order to produce a flow of electricity. There are several solar cells that are connected together ( usually 60 or 72 ) in each panel. Individual cells comprises both a negative layer and a positive one which combines perfectly to create an electrical field in which the energy is generated.

The boron that’s within the bottom layer generates the positive charge, while the phosphorous found in the silicon layer produces the negative charge. In order to convert the sun’s rays into the energy that’s going to be transported from the panels to the inverter, the two field will interact with one another.

In other words, solar panels work by turning photons from the sunlight into direct current which is transmitted to the inverter. Once it gets to the inverter, it’s then translated to alternating current and send this current to to your electric box which powers the entire home. If you do not wish to reduce the high bills that’s associated with renting power from the grid, the solar energy system is an efficient and affordable way to achieve this aim.

If you’re thinking about the possibility of installing a ground source heat pump in your home, then it’s normal to consider how efficient they’re in heating up a house before going ahead to make a purchase decision. In this article, we are going to address this question to help you make an informed purchase decision.

We know you’d prefer a single, accurate answer to this question, but the fact is, there are several influencing factors that can play a key role in the efficiency of a ground source heat pump installation. These factors include whether or not the property is well insulated, the fitting of a well designed system and the quality of its installation, the heat source that’s being used as well as the heating distribution system and its size ( under floor heating or radiators ).

The Coefficient of Performance ( CoP) measurement is used to imply the efficiency of a heat pump. This is basically the ratio between the amount of heat energy generated by the ground source heat pump and the amount of electrical energy or fuel it consumes. Therefore, the Seasonal Coefficient of Performance ( SCoP) is usually taken as a realistic measurement to cover throughout the year as its based on CoP at varying conditions as well as a standardized climate.

You must, however, note that there is no established Coefficient of Performance for ground source heat pumps as they can be influenced by a lot of factors as well as testing conditions. When they’re properly fitted, ground source heat pumps can achieve a quite high Coefficient of Performance.

Generally, a ground source heat pump can generate about 3 to 4 kilowatts (kW) of heat for every 1 kilowatt to electricity or fuel it consumes. It’s able to achieve a higher efficiency when compared to its counterparts by using the freely available heat energy from the ground.

Asides from the fact that solar energy can be converted into electricity with the help of solar panels, there’s also another pretty cool way the sun’s power can be harnessed - solar thermal technologies. These technologies are able to convert sunlight into heat rather than power and these are in fact the very first solar energy products that were commercialized in the United Kingdom. Solar thermal panels, in a similar way to solar PVs, can help in minimizing your carbon footprint while also assisting you to save good money on your energy bills by providing the much needed coverage for your heating needs with the help of a renewable energy source that’s totally free.

Solar thermal panels provides some great benefits which is capable of making all homeowners in the UK consider installing one in their respective homes. Let’s take a closer look at these benefits.

✓ When compared to solar PV panels, they’re a more affordable heating option and also have a shorter payback period.

✓ Solar thermal panels are more efficient than PV panels due to the fact that the heat waves are able to hold more energy than sunlight and also because there’s no electricity transformation process.

✓ Solar thermal panels are able to operate in cold climates, strong wind as well as overcast weather, and make use of an energy storage system.

✓ They can help you save about 600kg of carbon dioxide emissions on an annual basis.

✓ Although most of the solar thermal panel systems come with a warranty usually within the range of 5 to 10 years, they’re able to last up to 25 years. What’s more? The require just a little maintenance, meaning the main cost you’d have to worry about is the cost of installation.

If you’re interested in getting a new air source heat pump, then you’d probably want to know if they’re really advantageous, cost effective and efficient. The fact is, there are a plethora of benefits that comes with using heat pumps which is a renewable alternative to warm up your home in the UK.

An air source heat pump can help you save money on energy bills while also minimizing your carbon footprint as compared to a gas or electric heating system. Another important benefit that comes with air source heat pump is the fact that they’re quire versatile and yet affordable. Generally, they can function either for heating or cooling purposes and they can also be incorporated for either heating of space or water. In fact, in order to achieve the target Net Zero by 2050, the UK government are looking to fit 19 million heat pumps in new builds. With significant rise in the deployment of heat pumps, the grants by the UK government enables this renewable energy source to become a lot more affordable to run while also helping to minimize the burden of the air source heat pump cost.

As perfect as it seems, this renewable source of energy also comes with a number of disadvantage which we’re going to list out. Let’s take a look!

• There must be sufficient space in your garden to accommodate the external condenser unit.
• The condenser unit can make a lot of noise and even blow colder air into their immediate area.
• Since they consume electricity to operate, this also means they’re not zero carbon unless the electricity is produced from a renewable source like solar panels etc.

If you look after your air source heat pump, it can last for over 20 years. Make sure you check it every year and get a registered or qualified installer to check it every 3-5 years to prolong its life. If in doubt, check the manufacturer’s maintenance instructions.

When you’re about to transform from the standard electricity to solar energy, what determines your solar system’s size is the amount of solar that’s required. The amount of solar that you’ll need, on the other hand, requires considering the end goal, be it to increase money savings, reduce environmental contamination, maximize Returns On Investment ( ROI), or just to copy what the neighbour’s done.

In order the determine the number of solar panels that is needed, the first step would be to calculate the number of kWhs that’s currently being used. A kWh is what’s used to determine the amount of energy that has been incorporated over time which the utility uses to bill you. What’s strongly recommended to create a suitable range is a 6 to 12 months average of your household electricity bill. Other factors that can play a key role in the determination of the number of solar panel needed include the following:

✓ Sunlight exposure hours. In order to know just how much energy your solar panels will generate, there’s a need to know the number of direct sunlight hours you should expect on a daily basis. For example if you stay in a region that’s usually very sunny, then it’ll be reasonable to expect more energy production per panel than regions that are usually cloudy.

✓ Angle and size of the roof. Roofs with a lot of workable space may require to let go of some efficiency opting for larger and cost effective panels to achieve the targeted energy. However not all homeowners have sufficient roof space or shade coverage for the solar panel they actually want. Also, the degree at which the roof slants will also determine if the sunlight is hitting the panels well enough and the amount of energy that can be generated thereof.

The more you’re at home during the day, the more you can save on your electricity bill, since solar panels generate electricity during the day. The Feed-in Tariff scheme (FITs) ended in March 2019, but the new Smart Export Guarantee (SEG) pays you, via your energy supplier, for the electricity you export back to the grid. With the savings involved in generating your own electricity and SEG payments, you can expect to save up to £390 per year on your electricity bill.

Like every other systems in your home, solar hot water systems will require periodic inspections as well as a regular maintenance in order to keep it running as efficiently as it should. Not only that, the various components will also require either repair or replacement from time to time. It’ll also be proactive to take the necessary precautions so as to prevent worrying issues like corrosion, scaling or freezing.

Is it a task you can handle on your own? Well, there are some inspections and maintenance activities you should be able to handle on your own, however, you’ll also require a qualified technician to carry out the more technical or complicated tasks. You should also take note that it may actually be more cost effective to have some systems replaced, shut off or removed completely than having it repaired. Here are some of the essential inspections that should be carried out on solar system components. They include:

✓ Collector soiling. Periodic cleaning of your collectors is important especially in dry and dusty climates.

✓ Plumbing, ductwork and wire connections. Check the pipe connections for fluid leaks. Examine duct connections and seals. Also make sure that all wire connections are tight.

✓ Roof penetrations. Flashing and sealant around the roof penetration should be checked to see that it’s in a good shape.

✓ Collector shading. Check for shading of the collectors on annual basis as this may greatly affect their performance.

✓ Support structures. Examine all bolts and nuts which connects the support structures to the collectors for tightness.

✓ Heat transfer fluids. Anti freeze solutions in liquid solar heating collectors will have to be replaced periodically. And this right here is a task that’s best handled by a licensed technician.
