Question 1

Is it worth getting a solar battery?

Accepted Answer

There are a few factors that will determine whether it’s worth getting a solar battery. They involve how much electricity you use, how often you’re at home and whether you receive any export payments.

To work out whether it’s worth getting a solar battery, you need to work out how much of the electricity you generate you’re using already. If you’re able to run all your appliances during the day while your solar panels generate electricity, then it sounds like you’re already using your electricity well. It might not be worth you getting a solar battery in this case.

However, if you’re not at home for a lot of the day, then you’ll be missing out on the electricity your panels are generating while the sun’s shining. If you install a solar battery system, you can store the electricity that your panels generate in the battery and use it when you get home. This will help you cut your electricity bills even further.

You’ll also need to consider whether you’re getting paid to export your electricity. If you’re on the Feed-in Tariff scheme (FITs) or receive payments from the Smart Export Guarantee (SEG), you’ll get paid for every unit of electricity you export to the National Grid. Before you decide whether it’s worth getting a solar battery, you’ll need to weigh up whether you’d be better off carrying on exporting your unused electricity rather than storing it to use yourself. If you’re unsure, visit the Energy Saving Trust’s website or speak to an MCS-registered installer who will be able to help you work out which is more cost-effective.

Question 2

How long do solar panels last?

Accepted Answer

How long your solar panels will last depends on their age and quality. Most modern solar panels have 20-30 year warranties, but this doesn’t mean that they’ll stop working at this point. Many will stay at a good efficiency level for up to 40 years, while others will start to decline earlier.

Question 3

Can I buy solar panels?

Accepted Answer

Yes, you can buy solar panels without having to have them installed by the same company. There are lots of online companies that will sell you single solar panel modules, but there are also lots of businesses that offer DIY solar panel kits with everything that you need to install solar panels yourself. If you’re looking to buy solar panels without installation, you should expect to spend around £4,000-5000 on a 3.5kW system, which is the average system installed in the UK. When you buy solar panels to install yourself, it’s worth bearing in mind that you won’t be eligible for Smart Export Guarantee (SEG) payments. To receive SEG payments, your solar panels need to be installed by an MCS-registered installer, and if any schemes come about in the future it’s likely that the rules will be the same. It’s also worth doing some sums before you decide to buy solar panels and install them yourself. An average solar panel system installed by an MCS-registered company will cost between £4,500-6,000. While that’s more expensive than a DIY solar panel kit, you can claim SEG payments. According to the Energy Saving Trust, you can make your money back on your solar panels within 16 years with the SEG, but without the SEG it could be up to 20 years – and that’s only if you’re at home all day to use the electricity. So before you go ahead and buy solar panels to install yourself, consider whether it would be better to get in touch with some solar companies to get quotes and see if it’s better to pay more upfront.

Question 4

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 5

Should I clean solar PV panels myself

Accepted Answer

If your solar panels are mounted on your roof and you require a ladder to reach them we would always recommend you get a professional to do the work for your own safety.

Question 6

Is it best to get solar panels installed by a professional?

Accepted Answer

Yes. It will always be best to get solar panels installed by a professional because they have gone through lots of training and have all the relevant qualifications to install solar panels correctly. Whenever you’re dealing with electricity, if something goes wrong it could cause a fire or you could electrocute yourself, so it’s always worth leaving it to the professionals. The other thing to bear in mind is that it’s best to get solar panels installed by a professional, MCS-registered engineer so you’re eligible for Smart Export Guarantee (SEG) payments. The SEG is a government-backed scheme where your energy supplier pays you for each unit of electricity you send back to the grid. Each supplier can set their own rate, but it must be above zero at all times, even if wholesale electricity prices dip below zero. According to the Energy Saving Trust, if you’re at home all day and live in the South East, combine the savings on your electricity bills with your SEG payments and you could save up to £330 a year, meaning the system could pay for itself within 16 years. If you don’t use an MCS-registered company to install your solar panels, you won’t be able to claim the SEG. It’s also unlikely that you’d be able to claim payments for any other schemes that may become available in the future, so it’s always best to leave your solar panel installation to the professionals.

Question 7

How long do solar panels last?

Accepted Answer

The lifetime of a solar panel depends on its quality and age. Generally, the older a solar panel gets, the less efficient it becomes. The majority of modern solar panels come with 20-30 year warranties, which means that they’ll stay at a good efficiency level for at least this long. Some panels can stay efficient for as long as 40 years, while others won’t last this long.

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%.
