Solar panels are a great source of energy with numerous benefits that comes with it. However, the main thing that puts off most homeowners or potential buyers is the fact that the equipment are usually very expensive. So if you’re planning to purchase solar panels to be installed in your home, then you’d probably want to know if it’s actually worth the investment or otherwise. In this article, we aim to give you a good insight into how solar panels works and if its a viable investment.

Generally, the length of time it will take for your solar panels to payback and whether you’ll be able to make money from them will be based on the following factors:

✓ The solar panel PV system’s cost.

✓ The amount of the generated electricity that you’re able to use.

✓ Whether as well as the amount you’re paid to the electricity you’re able to generate and export.

To know whether your solar panels are truly worth it, then a higher initial cost to fit the system will require to be settled with the amount you’re able to save through the use of the renewable electricity it produces, rather than making purchases from your electricity company. In other words, the more renewable energy you’re able to use, the more savings you make. If you’re registered for the FIT and paid per kWh of electricity produced, for 50 percent of that, which is assumed to be exported to the grid. Therefore, if you’re able to use more than 50 percent, you’ll be able to benefit from the investment.

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 outside the house 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.

Tesla’s top-of-the-range battery storage system is still one of the most expensive on the market. It has a huge 13.5kWh usable capacity and can even keep you up and running during a power cut. But how long does a Tesla Powerwall battery last? And does this mean it’s worth investing in one?

The Tesla Powerwall 2.0 comes with a 10-year warranty. But Tesla says that it should last way beyond this – at least 5 years longer. The standard warranty says that it should work at 70% capacity for the full 10 years – so if it loses more than 30% of its storage capacity within that time, it should still be covered.

While the Tesla Powerwall does last a long time, it has a large capacity that most average households won’t require, and it’s a costly option. After installation, the Powerwall 2.0 will set you back between £6,500 and £9,000, so ideally you want it to last past its 10-year warranty.

Before you splash out, consider the size of the solar panel system you want to install or you already have. Will it generate enough electricity to make it worth storing in the Powerwall? If not, are you expecting to upgrade your solar panels to a larger system in the future? If you are, then it might be worth investing in a Powerwall. It might also be better to wait until you come to upgrade your solar panels – the solar battery price trend is going the same way as solar panels, so they will probably continue to decrease in price as more people adopt the technology.

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.

If you happen to live in a quiet, serene environment ( or just cherish being in one) and wish to have an air source heat pump installed on your property, then you’d probably want to know just how noisy these renewable energy source are. In this post, we aim to provide answers to this question and more. Let’s take a look!

There is no short and direct answer to this question as air source heat pumps are available in varying shapes and sizes which makes the sound as well as volume of their noise different between models and manufacturers. However, as a result of government regulations, most of the contemporary air source heat pumps are able to function a lot quieter when compared to the older models. As you would have expected, modern air source heat pumps shouldn’t produce more than a low whirring sound provided they’re functioning as they should with no faults. On the other hand, the volume of the sound generated is largely dependent on the amount of work the air source heat pump is doing. This implies that a greater work load will generate a louder noise. This is due to the fan’s speed which works to absorb warm air into the compressor.

In order not to disturb the neighbours, noise pollution is normally determined at the design stage of the air source heat pump installation. The unit to be placed outdoor will typically be positioned as far from the neighbours property as possible and it’s also a great idea not to put the box directly under any windows. Overall, it’s always advisable to go for the newer models which tend to be better designed with thicker chassis and quieter fans.

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.

How Many Solar Panels And Batteries To Power A House?

Do you wish to know the number of solar panels and batteries sufficient for a house? Well, this is a frequently asked question in the solar world which would be very difficult to provide an accurate answer. This is basically down to the fact that all homes are unique with different sizes as well as amount of daily energy requirements. As a result, the number of solar panels and batteries needed would be unique to the house in question. However, we’ll consider the varying influencing factors that will go a long way to help calculate the number of panels and batteries needed to power a house.

First and foremost, let’s take a look at the solar panels. You’d have to start here by putting into consideration all household appliances that makes use of power in the house to get a good idea of how many that’ll be needed.

• How Many Watts Is Being Used In The House On A Daily Basis?

To determine this, simply go through your utility bill for kilowatt-hours (kWh). This varies amongst homes and being able to identify your daily average energy usage will assist you in getting your solar needs.

• What Is The Number Of The Peak Sunlight Hours At The House’s Location?

Having in mind that the solar panels only work when under direct sunlight, the first step to determine the peak sunlight hours. Once determined, you can then multiply the figure in hours by the house’s hourly energy usage and divide by the solar panel’s wattage.

Overall for a 1500 square foot house, the number of solar panels that’ll be required should fall around 15 to 18.

Meanwhile for batteries, there are also some factors to be considered to determine the number of batteries that is required to power a house. These factors include the house’s power or electricity usage, the period of time in which the battery will be used as well as the battery’ specifications.
