Solar Panel Installer FAQs

How much are Tesla solar batteries?
Tesla solar batteries are some of the most expensive solar battery storage systems on the market. The Powerwall and Powerwall 2.0 are both excellent options for homes that generate a lot of electricity from their solar panels, but they might not be worth it for those that only have small solar panel systems. But exactly how much are Tesla solar batteries? Since the Tesla Powerwall 2.0 is the latest solar battery, we’ll focus on this one. With installation, you can expect to pay anywhere between £6,500 and £9,000. Other lithium-ion batteries, like SolaX or the LG Chem, will cost around £4,000, so you can see the difference in price. The benefit of the Tesla solar batteries is that they have a huge capacity. Most battery storage systems have a useable capacity of somewhere between 4-8 kWh, whereas the Powerwall has a useable capacity of 13.5 kWh. This is excellent if you have a large solar panel system that generates a lot of electricity, since you’ll be able to store all of it to use yourself rather than sending any back to the grid. However, if your system can’t generate that much, it might not be worth spending the extra money on a Powerwall. Another thing to consider is how long Tesla solar batteries last. The Powerwall 2.0’s standard warranty is 10 years, and Tesla state that it should work at at least 70% capacity for those 10 years. That’s a pretty good warranty, and Tesla says that the battery should last way beyond that. So you could have the Powerwall for around 20 years, making it seem like a better investment. Just consider whether you need such a high-capacity battery before making your purchase.
How much do solar batteries cost?
How much solar batteries cost depends on the brand and type of battery and its capacity. At the moment, the cost is quite high because the technology is still new – but they will probably reduce, just like we saw the cost of solar panels reduce as the technology became more popular. It’s a great idea to get a solar battery installed with your solar panel system if you’re out most of the day. If you didn’t have a battery, all that electricity would simply go to the National Grid – but if you have a storage system, then while your solar panels are generating electricity in the day, it would get stored in the battery ready for you to use when you get home. Lithium-ion solar batteries are the most widely-used ones at the moment because they generally have a higher capacity and are more cost-effective. For a 3-4kWh battery, which would store enough electricity for a typical 4kW solar panel system, it will set you back an average of £3,400. If you need a larger battery, it could cost anywhere up to £6,000. Lead acid batteries are cheaper, and it can seem tempting to ask an installer to fit one for you – but they aren’t cheaper in the long run. While a 4kWh lead acid battery may only cost around £2,000, their life cycle is only around 1,800 cycles. A lithium-ion battery that costs around £4,000 would have a life cycle of about 4,000 cycles. That means that while the upfront cost is more, you won’t have to replace it as quickly as a lead acid one.
Can you install commercial solar panels on a flat roof?

With the numerous benefits that comes with the installation of solar panels, it should not be an option for just a few just because of the size and/or pitch of their roof. A number of individuals with flat roofs decide against solar panels due to the fact that they believe that the panels can’t be installed due to the lack of direct sunlight. However, in truth, this thought is absolutely incorrect. This is because it is actually very possible to fit solar panels on flat roofs and you can also benefit from a good amount of electricity that’ll be generated over time. In this post, we’re going to look at the possibilities involved in the installation of commercial solar panels on a flat roof. Let’s get started!

 

In reality, flat roof solar systems are mostly found on commercial buildings as their roof is typically made to be flat. Although, it’s important to note that it’s absolutely possible for them to be fitted on domestic properties too. The type of solar array that’s installed makes use of the same type of solar panel as a conventional system, however, there are some considerations that’ll have to be made moving forward. The array must be able to self clean during the rainy season while also avoiding damage whenever there’s a strong wind. The installation company you choose should take the pitch of the system into account, so as to make sure that its able to capture as much energy from the sun as possible. And that’s exactly why you should consider the use of thin film solar cells which are very flexible and moves with the sun as the day goes by, securing as much sunlight as possible as its always in direct light.

can solar thermal be used for central heating?

If you’re thinking about getting a solar thermal system for your home, it’s normal to consider the possibility of using the system for central heating. So is this viable? In this article, you’ll learn how solar thermal panels can be incorporated for heating. Let’s have a closer look!

Heating and hot water systems, on the average, takes up a sizeable part ( up to 70 percent) of our energy bills. Now take a moment to imagine how cool it’ll be to generate your own hot water for free without having to depend on any supplier which in turn significantly reduces your energy bills. Well, this is exactly the work of central heating systems that are powered by solar. That’s super cool, right? Well, let’s have a look at how this works.

While solar panels generates electricity, solar thermal panels produces heat for hot water production. However, what’s important is the fact that they both make use of the sun’s natural energy to provide us with a free and renewable energy we can use in our homes. Here’s how it works.

Solar thermal panels directed at central heating incorporates the sun’s natural energy to heat water in a storage cylinder which is then available for use at home. These solar thermal panels are exposed to the sunlight by fitting them on the roof of the home. Generally, they’ll include tubes that contains liquid whose job is to collect the heat and then transfer it to a hot water cylinder that’s solar compatible in your home. The heat is generated for free and is also renewable. This is help you save lots of money on oil, gas and even electricity which you purchase to power the cylinder.

Can I install solar thermal panels myself?
In theory, you can install solar thermal panels yourself. But it’s best to leave it to professionals. We’ll explain why here. Solar thermal panels work in a similar way to solar PV panels. They use collectors, in the form of evacuated tubes or flat plate collectors, to collect heat from the sun and use it to heat up water that’s stored in a hot water cylinder. You can use a boiler or immersion heater as a back-up to heat the water further so it’s at the temperature you want. So should you install a solar thermal system yourself? It certainly seems tempting since you can buy full solar thermal DIY kits with everything you need for £1,500 to £2,000. To have a solar hot water system installed by a professional, you’re looking at between £5,000 and £6,000, so it looks like there’s a significant saving to be made. However, if you want to take advantage of the Renewable Heat Incentive (RHI) payments, which is a Government scheme where you’re paid for using a renewable energy source to heat your home and/or its hot water, you can’t install it yourself. You need to engage a Microgeneration Certification Scheme-registered installer who can issue you with a certificate to say that the solar thermal panels have been installed correctly. For a 4m2 system that serves a 4-person household, the payments could be up to £375 per year. That means you could pay your system off within 14 years, and that’s not taking into account any of the savings you’ll make on your energy bills. So, while you can install solar thermal panels yourself, it’s much better in the long term to have them installed by an MCS-registered company.
what size solar battery do I need?

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.
Can solar panels cause fires?
It’s only likely that solar panels will cause fires if they are installed incorrectly. The safest thing to do is ask an MCS-registered engineer to install your panels as they have all the relevant qualifications and training in handling electricity. If you choose a reputable company that can prove they have the right certifications, it’s highly unlikely that your solar panels will cause a fire. It’s important to remember that solar PV panels can’t start a fire themselves. It’s other parts that could become faulty that would then lead to a fire. For example, if the connectors in the system aren’t seamed properly, it could cause arcing and overheating, which could then cause the panels to set alight. Another possibility is that the junction box overheats and starts a fire. The junction box is found on the rear side of the solar panel and enables the electrical connection via a connector. Of course, since solar panels harness electricity, there is always a small fire risk – just like there is with any electrical appliance in your home. But there are some precautions you can take to reduce your risk of fire from solar panels:
  • Don’t buy cheap solar panels – while it might seem tempting, make sure you choose MCS-certified solar panels. Any reputable installer will recommend high quality solar panels, which is another reason to have them professionally installed rather than doing it yourself.
  • Ensure that your installer uses non-combustible mounting systems and frames.
  • Check your system regularly for signs of pests gnawing through cables.
  • Keep your solar panel system regularly maintained with proper testing and servicing carried out as recommended by your installer.
  • If something doesn’t look right to you, get in touch with your installer and ask – they should be more than happy to help.
How do solar panels work?

Solar PV panels work by converting sunlight into electricity. They’re made up of photovoltaic cells, which take in the sun’s rays and turn it into direct current (DC) electricity. The current is then channelled into an inverter, which converts it to alternating current (AC).

Once converted to AC, the electricity is ready to use. It’s fed through a meter and into your property’s consumer unit, and is automatically used to power appliances and heating systems. Your system will automatically switch between your solar electricity supply and the national grid, and export any solar electricity you don’t use to the national grid.
