Question 1

Which solar battery is the best?

Accepted Answer

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.

Question 2

Can solar panels cause fires?

Accepted Answer

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.

Question 3

Can Solar Panels be installed on an office building?

Accepted Answer

With energy prices rising steadily over the past couple of years, it’s little surprise several individuals are now seeking other options for powering their commercial and office buildings. With that said, the most common energy saving solutions incorporated by a lot of people are solar panels and wind turbines – the former being the favourite of most. Not only because they feature fewer moving parts, but also because they require less maintenance. So, can solar panels be installed on an office building? The short and simple answer to this question is yes, solar panels can definitely be installed on an office building. They’re noiseless, requires minimal maintenance, reduces your carbon footprint and saves you money. However, there’s the need to ensure that the best solar panels are installed on your office building to be able to fully enjoy these aforementioned benefits and more. So how do you go about that? Let’s take a look! If you want to install a solar panel, you’d discover that they come in various sizes, quality as well as cost. It’s important to always consider the panel’s size and select one that’s appropriate for your office roof as well as power needs. Furthermore, the efficiency is also crucial. When you get an efficient system, this is able to charge the batteries a lot quicker with a higher energy output, meaning more energy savings for you. What’s more? The durability of the panel is also important as a panel that’s durable comes with quality parts which helps you avoid downtimes at work. Finally, you should also consider a solar panel with a warranty which covers a more extended period. Several panels come with warranties of over ten years, but if you can get the one of over 20 years then the better.

Question 4

How much do solar batteries cost?

Accepted Answer

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.

Question 5

how much do commercial solar panels cost?

Accepted Answer

There are a wide range of benefits you stand to derive by installing solar panels for your business operations. Not only can it help you save money, but it can also go a long way to help reduce your business’ environmental footprint. Regardless of whether your company is big or small, it can still benefit immensely by making use of solar panels. If you’re considering the installation of solar panels in your business environment, then you probably want to know just how much it’ll cost to complete the project. In order to help you make the most informed purchase decision, we’ve created this post to give you a good insight into commercial solar panel pricing. Let’s take a look!

Generally, the cost of commercial solar panels is within the range of £16000 to £70000 for small to mid-sized companies. However, there are a number of factors that can influence the cost of commercial solar panels which includes the size of the roof, the amount of energy that’s generated as well as the number incorporated. There is a need to evaluate the cost of solar panels so as to determine whether or not they’re a feasible option for your business. In order to determine the amount of energy your company uses per month, simply take a closer look at your utility bill. This should indicate just how much energy you use per month as well as how much the utility company charges per kW. In general, most small to medium sized companies will incorporate 30,000 to 50,000 kWh annually and you can expect the cost to differ based on your location and the size of your system. The rule of thumb with larger systems is to calculate using £1000 per kW, plus VAT as the yardstick.

Question 6

Is there enough sun for solar panels in the UK?

Accepted Answer

It may be hard to believe with the summers we have in the UK, but there is more than enough sunlight to power solar panels. Solar PV (photovoltaic) panels operate in daylight, rather than needing direct rays from the sun so they&rsquo;ll work throughout the year.

Question 7

Which commercial properties suit 11-50kW solar panels?

Accepted Answer

It’s vital to purchase a solar panel system that suits your property. If you’re investing in a solar panel system, it makes the most financial sense to get the biggest one possible. However, whether you can do this or not depends on budget and space.

Here’s an idea of how much roof or ground space you’ll need to install a few different sizes of commercial solar panel system.

Solar panel system size, No. of solar panels, Approximate area required

11kW, 44, 64m²

20kW, 80, 116m²

30kW, 120, 173m²

40kW, 160, 231m²

50kW, 200, 288m²

Question 8

How long do home solar batteries last?

Accepted Answer

How long home solar batteries last depends on the type of battery you have and how often it’s charged and discharged (when electricity is fed into it, then used later on). Generally speaking, a home solar battery should last between 5 and 15 years. Lithium-ion batteries last longer than lead acid batteries. Lithium-ion batteries are more common these days because they’re more cost effective. A lead acid battery is the cheaper option at around £2,000, but it’s likely to last between 5-8 years. On the other hand, a lithium-ion battery may set you back around £4,000, but will last between 11-15 years. So you can see that it’s well worth choosing a lithium-ion home solar battery. It’s also worth considering that a solar battery’s lifespan will be reduced if you over-discharge it. When your home solar battery is installed, you’ll be left a manual which will tell you its depth of discharge, or DoD. This means how much you can use the battery before recharging it – it's not as simple as letting the battery run down to 0% then charging it again. In fact, this can significantly shorten your battery’s lifespan. If your solar battery system’s DoD is 80% and its capacity is 5kW, make sure you charge it before you use up 4kW to help prolong its life. Luckily, most lithium-ion batteries have a DoD of 80% or more, so you don’t need to worry about not being able to use much of the electricity stored in your home solar battery. This is another reason to use them over lead acid batteries, because their DoD can be as low as 50%.
