Renewable Energy Specialist FAQs

how much energy does a solar panel produce?

If you’re looking to purchase and install a solar system for your home or property, then knowing the amount of energy a solar panel can produce can go a long way to help you determine just how much solar panels that’ll be needed to power your entire house. In this article, we’ll give you an idea of the amount of energy that can be generated by a solar panel to help you make informed decisions going ahead.

First and foremost, you should note that each and every solar panel is rated by how much direct current power they’re able to generate under standard testing conditions. The output of a solar panel is given in watts units (W) and it stands for the theoretical power generation of the panel under direct sunlight as well as temperature conditions. Generally, several domestic solar panels possesses power output ratings which ranges from 250 watts to 400 watts. And as you would have expected, the higher power ratings are preferable when compared to the lower power ratings. What’s more? The total wattage of your solar panels will greatly influence a major part of your overall solar system cost.

Assuming you’re able to get just about 5 hours of direct sunlight every day, you can determine the output of your solar panel in this way - 5 hours x 290 watts ( wattage example of a premium solar panel) = 1450 watts-hours or approximately 1.5 kilowatts per hour (kWh). hence, the individual solar panel output in your array should be able to generate about 500 to 550 kWh of energy every year. This is sufficient energy to power some small appliances without problems.

how efficient are ground source heat pumps?

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 do I connect solar panels to a battery?

Most people want to connect solar panels to a battery when they’re not at home all day to use the electricity they generate, or generate more than they consume over a day. Solar batteries are a great way to maximise the savings on your energy bills since you can use every unit of electricity you generate.

If you want to connect your solar panels to a battery, the best – and safest – way is to ask an MCS-registered company to do it for you. They’ve had lots of training and hold qualifications in handling electricity and installing solar batteries, so they will be able to recommend the best battery for your solar panels and for the among of electricity you use. Some of the brands they might recommend include Tesla, SolarEdge and SolaX, but there are many more to choose from. If you want to send electricity to the grid from your battery to receive Smart Export Guarantee (SEG) payments, it’s also worth leaving installation up to a registered installer. This is because you might not be eligible for payments if your battery wasn’t installed by an MCS-registered company.

However, if you do want to have a go at connecting your solar panels to a battery, it’s worth finding out whether your system is ‘storage ready’. Most relatively new systems will be, since batteries are becoming more commonplace. If your solar panels are storage ready, they will have an inverter that can easily have a battery added to it. If this is the case, then you should be able to buy the solar battery you want and follow the manufacturer's instructions to install it.

But it’s worth remembering that electricity is extremely dangerous when handled improperly. If you don’t get the solar battery connected properly and something goes wrong, it could cause a fire or you could electrocute yourself. If a fire breaks out due to your battery, it’s unlikely that your home insurance company would pay out since you connected the battery yourself. That’s why it’s always worth speaking to a registered installer to install a solar battery storage system for you.

how does a ground source heat pump work in winter?

Are you currently considering installing a ground source heat pump in your home? Well, a heat pump can be a great alternative when compared to gas or oil boiler, however, you may also be worried about the operating efficiency of this heating system if you live in a cold climate or during the winter months. However, in reality, there’s nothing to be worried about!

A ground source heat pump works by incorporating the natural heat that’s typically found in the ground or groundwater. In other words, this type of heat pump doesn’t make use of fossil fuels to heat your home while it can also minimize carbon emissions that may pose a huge risk to the environment. This makes a popular option especially amongst home and property owners who are very environment conscious and prefers to utilize more renewable sources of energy.

However in a place such as the UK where the temperature can drop to around -10℃ during the winter months, it may get you thinking whether there’ll be enough heat in the ground to warm up your home. Let’s have a look.

In the UK, the temperature of the ground doesn’t normally fall less than 10℃. This is still enough heat for the ground source heat pump to warm up your home. In other words, as long as you purchase the right one, your ground source heat pump will continue to work just fine during the cold months. Due to the fact that every heat pump varies, you will need the right equipments so as to ensure the heat pump works well throughout the winter. This is usually not an issue in the UK, but same can not be said of colder places like Canada and North America.

How many types of air source heat pumps are there?

There are two main types of air source heat pump: air-to-water and air-to-air. They work in different ways and have different advantages and disadvantages. Make sure you do your research so you know which one is best for you. Alternatively a registered installer will be able to determine the best type for your property.

how much to install solar panels and battery?

How Much To Install Solar Panels And Battery?

Are you thinking about installing solar panels and battery in your home and wondering how much the installation is going to cost? Well, you’re not alone. This is one of the most commonly asked questions in the solar world, but unfortunately a precise answer can not be provided. This is mainly due to the fact that solar panel systems come in varying sizes which is the main influencing factor that determines how much electricity that can be generated. In other words, the larger the system, the more the electricity that’ll be produced to your home’s benefit.

Generally, for a solar system size of 1kW, the average cost of the solar panel ranges between £1800 to £1850, 2kW is between £3600 to £3700, solar panel size of 3kW ranges between £5500 to £5600 and finally, 4kW is between £6000 to £6050. For example, with the aforementioned prices in mind, the cost of solar panels for a standard 3 bedroom house will range between £5520 to £6040 as the high electricity demands will need the installation of 3 to 4kW solar system size.

Meanwhile the installation cost of solar batteries is also dependent on a number of influencing factors like the size as well as the make of the battery. Generally, you can expect to spend within the range of £500 to £2000 to install your batteries depending on aforementioned factors. In the event whereby you’ll be retrofitting, you might also need to include an additional cost of £1000 for an inverter. However, it’s important to note that there are only quite a few hybrid systems which are able to combine a battery storage with an inverter.

Are heat pumps noisy?

Air source heat pumps do make a bit of noise. However, it’s the external unit that makes the noise, minimising disruption in your home. And while it’s a good idea to ensure your external unit isn’t located directly under your bedroom window or very close to a neighbour’s property, it won’t be louder than 40-60 decibels. In many cases, this is actually quieter than a fossil fuel-powered boiler.

are air source heat pumps classed as renewable energy?

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.
