Renewable Energy Specialist FAQs

do solar hot water systems need servicing?

Like every other systems in your home, solar hot water systems will require periodic inspections as well as a regular maintenance in order to keep it running as efficiently as it should. Not only that, the various components will also require either repair or replacement from time to time. It’ll also be proactive to take the necessary precautions so as to prevent worrying issues like corrosion, scaling or freezing.

Is it a task you can handle on your own? Well, there are some inspections and maintenance activities you should be able to handle on your own, however, you’ll also require a qualified technician to carry out the more technical or complicated tasks. You should also take note that it may actually be more cost effective to have some systems replaced, shut off or removed completely than having it repaired. Here are some of the essential inspections that should be carried out on solar system components. They include:

✓ Collector soiling. Periodic cleaning of your collectors is important especially in dry and dusty climates.

✓ Plumbing, ductwork and wire connections. Check the pipe connections for fluid leaks. Examine duct connections and seals. Also make sure that all wire connections are tight.

✓ Roof penetrations. Flashing and sealant around the roof penetration should be checked to see that it’s in a good shape.

✓ Collector shading. Check for shading of the collectors on annual basis as this may greatly affect their performance.

✓ Support structures. Examine all bolts and nuts which connects the support structures to the collectors for tightness.

✓ Heat transfer fluids. Anti freeze solutions in liquid solar heating collectors will have to be replaced periodically. And this right here is a task that’s best handled by a licensed technician.

Which solar battery is the best?
With so many different solar batteries on the market these days, it can be difficult to know which solar battery is the best. Luckily, we’ve picked out some of the best solar batteries on the market so you can take a look at their stats and figure out which one is best for you. Powervault 3: 8 kWh model This lithium-polymer solar battery has a useable capacity of 8 kWh and a depth of discharge (Dod) of 100%. It’s covered by warranty for 10 years. Cost: From £7,020 Tesla Powerwall 2.0 The famous Tesla Powerwall has a huge useable capacity of 13.5 kWh and also has a 10-year warranty, with a guarantee that it will work at 70% capacity during those 10 years. It’s a lithium-ion battery. Cost: From £6,500 Powervault 3: 4 kWh version This more modest solar battery from Powervault has a capacity of 4 kWh, but benefits from the same warranty length and DoD as its 8 kWh brother. Cost: From £4,470 SolaX 3.3 This more affordable solar battery from SolaX has a 10-year warranty and a good DoD of 90%. Cost: From £4,010 LG Chem RESU 6.5 LG are an up-and-coming player in the solar market and their 6.5 kWh battery is one of the most affordable on the market. Its DoD is 90% and it comes with a 10-year warranty. Cost: From £3,043 To decide which solar battery is best for you, you need to consider:
  • 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
When you’ve made these decisions, you can narrow down your choices. It’s also worth asking a few MCS-registered installers for their opinions on what they think would be best. Of course, they want to sell you whichever brand they supply, but they probably chose this for a reason. Ask them to give you a few pros and cons for the brands they recommend and see if this matches up with your research.
how many solar panels and batteries do i need?

How Many Solar Panels And Batteries Do I Need?

Are you presently considering adding a solar system to your home? With several homeowners in the UK using solar now, many more are realizing the numerous benefits they stand to derive by getting one. Therefore, if you’re thinking about adding the system to your home but do not know where to start, you’ve come to the right place.

Here, we’ll help you calculate the number of solar panels and batteries you’ll need to power your home. Starting from the panels, you can begin by taken into account everything that makes use of power in your home to get a good idea of how many you’ll need.

• Firstly, you’ll have to determine the number of watts you use. 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.

• Secondly, you have to determine the peak sunlight hours - having in mind that the solar panels only work when under direct sunlight. Once determined, you can then multiply the figure in hours by your home’s hourly energy usage and divide by your selected solar panel’s wattage.

Generally for a 1500 square foot house, you might need around 15 to 18 solar panels to cover the house’s electricity.

Meanwhile for batteries, there are also some factors to be considered to determine the number of batteries you’ll need for your house. These factors include your home’s power or electricity usage, the period of time in which the battery will be used as well as the battery’ specifications. Once done, you’ll be able to calculate the number of batteries required by your home.

how much does an air source heat pump cost?

Are you interested in installing an air source heat pump in your home or property? If yes, then you’d probably want to know just how much this is going to cost. Well, so are many other potential investors in the unit and we aim to answer this question once and for all. In this post, you’re going to discover the price range at which your new air source heat pump will fall in.

 

As simple as it seems, the cost of an air source heat pump can’t be accurate and straightforward as there are a number of factors that greatly influences the price. These influencing factors include the size of the heat pump, the system’s complexity, your personal preference - whether simple or advanced controls, and lots more. However, according to Energy Saving Trust, an air-to-water heat pump should fall within the range of £7000 to about £11000. What’s more? You’ll also need to put into consideration the cost of upgrading your radiators or fitting underfloor heating which can also cost you thousands of pounds.

 

In general, the main cost of a heat pump is the upfront cost of making a purchase as well as installing it. The heat pump will consume a little amount of electricity and the running costs are also relatively low. The amount your air source heat pump will cost largely depends on your home’s size, the temperature you want your home or property to be as well as how properly insulated your home is.

 

The period of time it’ll take to recoup your investment in the system in energy savings will also depend on a wide range of factors including the price you pay for electricity, how efficiently the system works, how you use the heat generated and more.

How long will a solar panel battery last once it's dark?

If you’re thinking about installing a solar system in your home or property, this is probably one of the things you’d like to know before making a purchase decision. Well, you’ve come to the right place! In this post, we’re going to give you a good insight into this to help you make the best informed decision possible moving forward. Let’s take a look!

First and foremost, it must be stated that providing a short and accurate answer to this question is nearly impossible as the amount of time a solar panel will last after dark is influenced by a number of factors. These factors include the size of your solar system, the battery size as well as your power usage. As you would have imagined, batteries are charged when there is excess energy that’s being produced by your solar system but it’s not being incorporated to power your home or property. More often than not, this occurs during the sunlight’s peak periods from about 10am to 2pm.

The time it’ll take for your battery to charge is influenced by the size of your solar system in Kilowatts, the size of your battery as well as the rate in which your system is being used. Your battery can be charged in a day or two, of course unless it’s an over-sized battery for your system.

When the sun sets and your solar panels can no longer directly run your appliances via electricity generation, the battery then kicks in. You will use about 1 to 2 kW’s of power if you’re watching TV, using the oven as well as lights internet etc. in other words, even a small solar panel battery will last all night. However, the same doesn’t apply if you’re having a party with running floodlights, three fridges and air conditioner as the battery will drain a lot faster.

what size ground source heat pump do i need?

The bigger the ground source heat pump, the better right? Wrong! And you’ll definitely be sorry to make such a huge mistake. When planning to install a heat pump, determining the size of the ground source heat pump is not as direct and straightforward as many homeowners would think. Here, you’ve got only a small margin for error. When the pump is too small, the heat pump will make use of the backup heater too often and in the event whereby the heat pump is too big, it’s going to short cycle. Both situations are preferably avoided as they’ll both leave you with an expensive and inefficient system.

To get the accurate size of a heat pump, there’s usually the need to hire the services of an expert and licensed heat pump installer who possesses a top notch design calculation software. In reality, the majority of inefficient systems are caused by a lack or poor understanding of the suitable design software.

There are many factors that can influence the calculation of a home’s heat pumps size. These includes

✓ Radiators and underfloor heating sizes

✓ Insulation, property fabric as well as heat loss

✓ The number of rooms in the property

✓ The types of rooms and their uses.

✓ The desired indoor temperature for varying rooms

✓ Seasonal temperature fluctuations.

Generally, a bigger house will require a bigger ground source heat pump. With an eye on the age of the property, heat loss as well as the types of the rooms, a house of about 100 square metre can require up to 4kW ground source heat pump. And for a house that’s about 200 square metre, the ground source heat pump also doubles to 8kW.

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.

What size home solar battery do I need?

The importance of selecting the right size battery for your home simply cannot be overemphasized. A lot of home and property owners are facing this challenge and understandably so. Selecting the right battery size for your needs depend on a number of factors which includes your motive for adding a battery, your electricity usage, your budget as well as your panel array size, be it new or existing. In this post, we’re going to take you through some of these factors to help you determine the right battery size for your home or property. Let’s take a look!

  • Your motive for getting a battery. While most people purchase a battery to wipe out their need to purchase electricity from the grid with the hope of making some savings, others add a battery so as to enjoy backup power. There are also some who just needs it to power their home with solar energy. It’ll not be economical to size a battery to effectively take you off the grid, but if your motive is to make savings, then you’ll should expect to purchase some electricity from the grid during the year.
  • Electricity usage. The average household uses about 16kWh of electricity on a daily basis. During the daylight hours, most of these household will use a third of their electricity when the solar panels are still generating electricity, while the remaining two third are purchased from the grid. In other words, you’ll require a minimum of 10kWh battery capacity if you were to use a battery to power the electricity you purchase from the grid.

For a typical British household, you’ll most likely need a 5kWh solar power system which normally generates about 17 to 21 kWh on a daily basis depending on your location in the UK.
