If you’re considering getting a solar thermal system, one of the first things that comes to mind is the possibility of the system functioning properly during the cold months. The short and simple answer to this question is yes, a solar thermal system works in the winter. However, the downside here is that it’ll be a lot less efficient when compared to how it operates during the warmer months or summer. As a result of this fact, you’ll likely need to rely more on your boiler, immersion heater or any other backup heating system during this period as your solar thermal system will fail to contribute as much as it does during the warmer months. So what exactly is the reason why solar thermal is less effective and less efficient in the winter period? Let’s have a look!

As you know, solar thermal system banks on the sun’s energy to heat the water for your home’s use. During the cold months or winter, the sunlight becomes a lot less available when compared to the warmer months, as a result, there’s less sunlight that’s available to be used for its solar energy. And even more so at the periods when the days are shorter or skies are clearly overcast.

Also having a great impact on a solar thermal system’s output is heavy snow. Flat plate collectors normally have the capacity to cope better during snowy conditions as the light that’s able to travel through the snow will heat up the absorber plate - thereby making the snow slide off more quickly. However, the case is contrary with evacuated tube collectors which possesses a form of vacuum insulation that’s crafted to minimize the loss of heat, meaning they can’t generate heat to melt and cause the snow to slide off in a similar way.

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.

So do you wish to take advantage of the heat generated by the ground to warm up your home by getting a ground source heating pump? If yes, then you’d also probably be wondering how much a ground source heat pump is going to cost so you can set a budget and start planning.

Installing and running ground source heat pump can cost between the range of £600 to £700 to run on an annual basis, meanwhile it can cost you within a range of £13,000 to £19,000 to have installed. However, you should take note that these prices can be by varying influencing factors such as the size of the installation as well as any other extra work that may needed to complete the job.

When it comes to estimating the time it takes to recover the initial cost of the system via energy savings, nothing is certain as this can be very hard to determine or predict. The main reason for this is due to the fact that it’s dependent on the efficiency of your heating system, the type of system you’re replacing ( whether or not you qualify for Renewable Heat Incentive -RHI payments ), the efficiency of your home’s insulation, how efficiently the system’s controls are being used and how the heat generated from the ground source heat pump would be put to use. However, to figure out how much you’ll save, the type of fuel replacing is perhaps the most essential. For a four bedroom detached house, you can save between a range of £1,200 to £1,300 for a LPG fuel replaced, £1,400 to £1,500 for an electricity fuel replaced, £600 to £700 for an oil fuel replaced and finally, £200 to £300 for a solid fuel replaced.

So, you’ve finally decided to go for solar? If yes, then you’d also probably find yourself trying to figure out exactly what solar battery size is needed to power your home or property. This is one of the most common questions when it comes to the solar system world and understandably so. In this article, we aim to give you an idea of the solar size you’d need to power your home or property before making a purchase decision. Let’s take a look!

The first thing to do if you find yourself asking this question is to identify the reason why you want to purchase the solar battery in the first place. For some individuals, they simply want to save some excess energy being fed back into the grid, while others just want protection from possible blackouts. There are also some environment-conscious home or property owners who makes this decision in order to create a carbon-neutral home. Another crucial factor to consider is your budget. A full solar storage system can be quite costly, although this is cheaper than a decade ago. Generally, the size of solar battery you’ll require depends on the following:

• How much energy you’re able to generate: The size of your solar array as well as its efficiency will influence the amount of power it’ll be able to supply to your home.
• Your daily energy usage needs: Daily energy usage can vary greatly between households depending on a number of factors. These factors include the number of occupants, geographical location, type of building, general household energy usage and more. Some may find that their solar system cover for most of their energy usage, while others find themselves still relying heavily on the grid.

No, air source heat pumps aren’t particularly noisy. Most models make about the same amount of noise as a boiler or fridge. And don't forget, the unit itself is fitted to the outside of your property so you won't hear a thing when you're indoors or at nightime!

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.

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.
