Renewable Energy Specialist FAQs

how does an air source heat pump work?

Air source heat pumps work by taking heat from the air and using it to heat your home. They absorb heat from the air into a fluid, which then goes to a compressor where it gets hotter. This heat is then used to warm up water or air, which is distributed around your home.

First and foremost, you should know that heat pump is simply a device whose primary function is the transmission of thermal energy from one spot to the other. A good example can be found in the refrigerators whereby the evaporation as well as cooling of a liquid is incorporated to lower the storage compartment’s temperature. In recent times, this whole technology is utilized to draw the potential thermal energy present in the air outside and transmit it directly to the home or property where it’s going to be compressed and the heat transferred with the help of a number of coils. This is exactly what an air source heat pump does as it absorbs heat from the air and convert it into a higher temperature using a compressor. How the air source heat pump works is really simple, it’s just like a refrigerator but in reverse. Let’s take a look!

  • The air source heat pump extracts heat present in the outside air into a liquid refrigerant at a reduced temperature.
  • The pump then compresses the liquid to increase its temperature with the help of electricity. Once done, it then compresses it back to liquid so as to free the heat stored.
  • The heat released is then directed to the radiators or under floor heating, while the ones left would be stored in the hot water cylinder.
  • The hot water that’s stored can be used for showers, baths as well as taps.

Overall, the air source heat pump is an efficient way to make your home warm. It makes use of electricity to function, but it should consume lower electrical energy than the heat it generates.

Does a solar battery work in a power cut?

If you’re thinking of adding a solar battery to your home, you might be wondering whether or not it’s going to work in a power cut. If yes, then you’re not alone as this is one of the most common questions asked when it comes to solar batteries. In this post, we aim to provide you with a detailed answer to solve this concern once and for all.

The answer to this question is, it depends. The main reason why your solar batteries will usually not work or provide your home with the much-needed back up power is as a result of the several threats it poses. You should be aware that both your solar panels and battery are connected to the main grid. When a power cut occurs, your engineers will have to operate on the grid. If the solar panels or batteries are in operation at the period there’s a high chance the engineers would be electrocuted by the electricity that’s being produced. As a result of this, solar inverters are usually designed to automatically switch off once a power cut occurs. However, it should also be noted that if your solar battery possesses backup functionality, you’ll be able to make use of your solar energy in the event of a power cut. In other words, what determines if your home battery would work in a power cut is the availability or otherwise of a backup functionality.

Furthermore, you might also wish to know if your solar panels will continue to charge the battery in a power cut. Well, this depends on the type of backup system you possess. There are some more affordable batteries that are designed to automatically release their stored energy upon the detection of a power cut. And this is mostly because the battery inverter is usually smaller than the solar inverter which allows the energy from the solar inverter to the transmitted to the battery - risking an overload. However, if otherwise, then energy can continue to be transmitted to the battery until its fully charged.

How do air source heat pumps work?

Air source heat pumps work by absorbing heat from the outside air and transferring it inside to heat up your property.

An air source heat pump has an outdoor unit containing a refrigerant. This absorbs heat from the air and passes into a compressor, where the temperature is increased. The heat then transfers either into water, which feeds into your wet heating system, or into air, which is dispersed around your property.

Air source heat pumps need electricity to run, but this is to power the compressor rather than directly generate heat.

Do I need planning permission for solar thermal panels?

Most domestic solar thermal panels do not need planning permission and are covered by permitted development rights. There are restrictions on the size and location of these systems. If you live in a conservation area or listed building, or want to install a very large solar thermal system, check with your local authority to see if you will need planning permission.

How do solar thermal panels work?

Solar thermal panels work by capturing heat directly from the sun and using it to heat water. This hot water is then passed through a coil to heat the water for your central heating system. Solar thermal systems are compatible with many existing conventional boilers with hot water tanks, and can be set up to feed in to your existing heating system.

How much do solar batteries cost?
How much solar batteries cost depends on the brand and type of battery and its capacity. At the moment, the cost is quite high because the technology is still new – but they will probably reduce, just like we saw the cost of solar panels reduce as the technology became more popular. It’s a great idea to get a solar battery installed with your solar panel system if you’re out most of the day. If you didn’t have a battery, all that electricity would simply go to the National Grid – but if you have a storage system, then while your solar panels are generating electricity in the day, it would get stored in the battery ready for you to use when you get home. Lithium-ion solar batteries are the most widely-used ones at the moment because they generally have a higher capacity and are more cost-effective. For a 3-4kWh battery, which would store enough electricity for a typical 4kW solar panel system, it will set you back an average of £3,400. If you need a larger battery, it could cost anywhere up to £6,000. Lead acid batteries are cheaper, and it can seem tempting to ask an installer to fit one for you – but they aren’t cheaper in the long run. While a 4kWh lead acid battery may only cost around £2,000, their life cycle is only around 1,800 cycles. A lithium-ion battery that costs around £4,000 would have a life cycle of about 4,000 cycles. That means that while the upfront cost is more, you won’t have to replace it as quickly as a lead acid one.
how many solar panels do i need?

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.

is solar thermal cost effective?

If you’re looking to install a solar thermal system in your home, this is usually one of the first concerns several homeowners have. Being fully aware that solar water heating systems are usually more expensive than their counterparts - the conventional water heating systems, the question arises whether or not you’ll be able to save some money from your solar water heating system in the long run. In this article, we aim provide an answer to this important question. Let’s take a closer look!

When it comes to solar thermal systems, the money you’ll be able to save in the long run depends on a wide range of factors. These factor includes:

✓ Your system’s performance.

✓ Your geographical location and solar resource

✓ Your household’s hot water demand

✓ Financing and incentive options that are available.

✓ The cost of fuel that’s being used for your alternative or backup water heating system, if you own one.

✓ The cost of conventional fuels such as oil, electricity or natural gas.

There are several benefits, however, that comes with the installation of a solar water heating system. Since the sun is absolutely free, future fuel shortages and price hikes will have little impact on you. Also, on the average if you decide to fit a solar thermal system your water heating bills is expected to drop about 50 percent to 80 percent. What’s more? The economics are even a lot more attractive when you’re just about to build a new home or refinancing. When you include the price of a solar water system in a 30 year mortgage, it’ll normally amount to very low price per month. Therefore, on a monthly basis you’ll be saving more and paying less.
