Solar panels provide an alternative to paying expensive National Grid energy rates, so primarily their first major benefit is helping to reduce bills. Solar PV panels will produce free electricity, whilst solar thermal panels generate heat for hot water and space heating. There are also payment incentives known as the Feed-in Tariff scheme (FITs) (for solar PV) and the Renewable Heat Incentive (for solar thermal) which guarantee a tax-free income for 20 years.

If you’re considering installing ground source heat pump, it’s likely you’re also wondering just how deep it’ll go into the ground to be efficient. Well, the initial step to take while determining the ground source heat pump’s design is to research the different options available to reduce the space heating as well as hot water demand. To achieve this, there must be an accurate measurement of energy efficiency which is usually done by getting an Energy Performance Certificate ( EPC) . This is helpful as such that it helps to identify the most suitable or the right size of heat pumps which will help reduce the consumption of energy, heat loss as well as hot water needs of the house.

Generally, ground source heat pumps are usually more compatible with new builds against retrofits. What’s more? The heat pump has two different types of loop systems :

✓ The open loop system and;

✓ The closed loop system.

The open loop system absorbs water from the ground and transfers this ground water via a heat pump to where it carries out the extraction of heat. Meanwhile the closed loop system extracts heat from the ground and incorporates a continuous loop of piping that’s linked to the indoor heat pump. There are a few types of closed loop system, these includes:

✓ The Horizontal Ground Source Heat Pump. This is installed in horizontal trenches of about 1 to 2 metres deep. This is more common in areas where land is readily available.

✓ The Vertical Ground Source Heat Pump. These boreholes are a more costly option but it’s also the best option when land is not readily available for horizontal installation. The insulation hole is dug at a minimum of 6 metres into the ground, while the entire piping will be at a depth of about 50 to 150 metres based on your home’s heat requirements as well as the ground’s composition.

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.

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.

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.

• 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

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 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.
