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 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 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.

• The power of your solar panel system – there's no point buying a higher capacity battery if your system will never generate enough electricity to charge it
• How often you think you will need to charge your battery
• Your budget
• Whether you care about having the latest technology and a recognisable brand name

Are you thinking of installing solar thermal systems in your home or property and wondering exactly how it works to generate electricity? Regardless of your motive, in this article you’ll learn in simple details how solar thermal is how solar thermal doesn't provide electricity for your home.

If you are looking to generate electricity for your home then Solar PV are able to generate electricity simply by absorbing and focusing sunlight in such a way to create a temperature level that’s high enough to generate the much needed electricity. There are two main components that comes with the solar energy collectors of each. These two components include, the reflectors ( mirrors), which works to absorb and concentrate the sunlight onto a receiver. In several types of the solar thermal power systems, a heat transfer fluid is then heated and distributed in the receiver so as to generate steam. Once the steam as been produced, it’s then transported to the turbine where it’s turned into a mechanical energy, which in turn powers the generator to produce electricity.

Solar thermal power or electric systems are usually embedded with a tracking system which keeps the sunlight concentrated on the receiver all day long as the sun changes position in the sky. They also come with a wide array of collectors which works of distribute the heat absorbed to a turbine as well as the generator. A lot of solar thermal power facilities will gave two or more plants with different arrays and generators.

Solar thermal power systems can also have a thermal energy storage system component whose work is to permit the solar collector system to heat an energy storage system during the day while energy storage system’s generated heat is incorporated in the production of electricity at night or during a cloudy weather when there’s not much sunlight.

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.

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.
