Question 1

How much is the Powerwall 2?

Accepted Answer

The Tesla Powerwall 2.0 is the second solar battery storage system from Elon Musk’s EV and clean energy company. It’s larger and more expensive than the original Powerwall, but it can store more electricity. So how much is the Powerwall 2.0? With installation, it will set you back between £6,500 and £9,000. But is it worth it? We’ll go through some of the top features so you can make your decision. The Powerwall 2 has a huge useable capacity of 13.5kWh. Most other solar batteries on the market have a capacity of around 4-6.5kWh, so it’s no surprise that it’s also one of the most expensive. If you’ve got a standard-size solar panel system on an average-sized home, you might not need a battery with such a big storage capacity. The Tesla Powerwall 2.0 is the only solar battery available in the UK to provide your home with an uninterruptable power supply (UPS) if you add the Backup Gateway 2. This means that if there’s a power cut, you won’t lose power – because your battery will keep running. It can also scan the weather forecast, so if there’s a storm it will ensure that your solar panels charge the battery in case you get a power cut. So while the Powerwall 2 is the probably the most expensive solar battery you can buy in the UK, if you live in a part of the country with a particular problem the power cuts or you have a large solar panel system, it might just be worth spending the money on it.

Question 2

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 3

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 4

What are solar panels made of?

Accepted Answer

Solar panels are made up of photovoltaic (PV) cells. These cells are made from silicon semiconductors, which absorb sunlight and convert it into electricity.

There are three main types of PV cell: monocrystalline solar cells, polycrystalline solar cells, and thin film solar cells. Monocrystalline cells are usually the most efficient and expensive, and thin film solar cells are the cheapest and least efficient. These are all made from silicone, but are manufactured in different ways.

Question 5

Who makes solar thermal panels?

Accepted Answer

There are a few trusted companies in the UK that make solar panels. While there are other solar thermal panels out there that are made by Chinese and American companies, we’ll focus on the brands with a longstanding presence in the UK since these are the panels MCS-registered solar companies are likely to recommend to you.

Viessmann, Worcester Bosch, Solar UK and Dimplex make some of the best solar thermal panels in the UK. Dimplex and Viessmann offer both flat plate and evacuated tube solar panels, while Solar UK only offers evacuated tubes. Worcester Bosch’s Greenskies range are all flat plate collectors. Viessmann’s panels come with a 5-year warranty, while Worcester Bosch and Dimplex offer extensive 10-year warranties. However, Solar UK offer a comprehensive 25-year warranty and guarantee that the panels will deliver the same level of performance for 25 years!

We’d recommend choosing evacuated tube solar thermal panels because they are the most efficient. While there won’t be much difference between evacuated tubes and flat plates in the summer, in the winter evacuated tubes are much better at taking heat from the sun than flat plates. Since our winters are long and cold with few daylight hours, we think it makes sense to go with evacuated tubes. However, if your priority is looks over maximising efficiency, you might want to choose flat plate collectors since they sit flat on the roof and look more like solar PV panels, whereas the evacuated tubes will stick out.

Question 6

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 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 much do solar thermal panels cost?

Accepted Answer

How much solar thermal panels cost in total will depend on whether you’re engaging an MCS-registered installer to fit them for you or whether you’re going to do it yourself. We’d always recommend that you get a reputable company to install them for you, since they have all the relevant skills and training to do the best job. However, there are DIY solar thermal panel kits out there that have everything you need to install them. If you get an MCS-registered company to install your solar thermal panels, you should expect to spend between £4,000 and £5,000. If you buy a solar thermal panel kit online, it will set you back between £1,500 and £2,000 - but you won’t be able to claim Renewable Heat Incentive (RHI) payments. The RHI is a Government scheme that pays you for every unit of heat that you generate from renewable sources, including solar thermal panels. If you’re in a 6-person household and you installed a 6m2 system, you could earn up to £525 per year for seven years. That means that you could pay off over half your system with these payments. Plus, if you’re switching from gas fuel, you can expect to save £60 a year on your bills, but switch from LPG and it could be as much as £100 a year. So while the cost of solar thermal panels will be more upfront if you choose to get them installed by an MCS-registered professional, you could make half the cost back in RHI payments and fuel bill savings, so it’s well worth getting them fitted properly.
