Question 1

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%.

Question 2

How much are Tesla solar batteries?

Accepted Answer

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.

Question 3

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 4

What are the benefits of installing solar panels?

Accepted Answer

Not only will you reduce your electricity bill by generating your own electricity with solar panels, but you can also earn money through the SEG which is offered by large energy suppliers. They&rsquo;ll pay you for the electricity you export back to the grid. You&rsquo;ll also reduce your carbon footprint, lessening your impact on the environment.

Question 5

How do solar thermal panels work?

Accepted Answer

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.

Question 6

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 7

Is solar thermal worth it in the UK?

Accepted Answer

We certainly think solar thermal is worth it in the UK. While we have cold winters that affects the amount of sunlight we get during those months, solar thermal panels can still generate a little heat in the winter on sunny days, and your back-up boiler or immersion heater can do the rest. The average cost of a 6m2 solar thermal system in the UK is £4,500. While that might seem like a lot of money up front, you’ll be able to make back some of that cost through Renewable Heat Incentive (RHI) payments. The RHI is a Government scheme that pays you for every unit of renewable heat that you generate, and a 6m2 system could earn you up to £525 per year over seven years. That means you could end up paying less than £1,000 for free renewable heat for your home! As well as the RHU, you’ll see a saving on your fuel bills since you’ll be less reliant on your traditional form of heating. If you have a natural gas boiler, you could save up to £60 a year on your bills, while if you’re switching from LPG the savings could be as much as £100 per year. So, we definitely think solar thermal is worth it in the UK! Plus, you’ll be reducing your carbon footprint and contributing to cleaner air for everyone in the country, so you can feel good knowing that you’re doing your bit.

Question 8

Which commercial property are 4-10kW commercial solar panels best for?

Accepted Answer

It’s important to get the right size solar panel system for your commercial property. Solar panels are usually installed on pitched roofs, although they can be fitted on stands on the ground if you have some unused outdoor space. The more panels you install, the more power you’ll generate, but there’s no point buying more panels than you have space for.

Solar panel system sizes are measured in kW. 4-10kW solar panel systems are usually too big for domestic properties but are ideal for smaller commercial properties. Here’s an idea of how many panels and space you’ll need for a few different system sizes:

System size, Number of panels, Area required (approximate)

4kW, 16, 23m²

6kW, 24, 35m²

8kW, 32, 46m²

10kw, 40, 58m²

Bear in mind that solar panels can’t be less than 30cm away from a roof edge, so you’ll need more space than the area that the panels take up.
