Solar Panel Installer FAQs

Is it best to get solar panels installed by a professional?
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.
do solar hot water systems need servicing?

Like every other systems in your home, solar hot water systems will require periodic inspections as well as a regular maintenance in order to keep it running as efficiently as it should. Not only that, the various components will also require either repair or replacement from time to time. It’ll also be proactive to take the necessary precautions so as to prevent worrying issues like corrosion, scaling or freezing.

Is it a task you can handle on your own? Well, there are some inspections and maintenance activities you should be able to handle on your own, however, you’ll also require a qualified technician to carry out the more technical or complicated tasks. You should also take note that it may actually be more cost effective to have some systems replaced, shut off or removed completely than having it repaired. Here are some of the essential inspections that should be carried out on solar system components. They include:

✓ Collector soiling. Periodic cleaning of your collectors is important especially in dry and dusty climates.

✓ Plumbing, ductwork and wire connections. Check the pipe connections for fluid leaks. Examine duct connections and seals. Also make sure that all wire connections are tight.

✓ Roof penetrations. Flashing and sealant around the roof penetration should be checked to see that it’s in a good shape.

✓ Collector shading. Check for shading of the collectors on annual basis as this may greatly affect their performance.

✓ Support structures. Examine all bolts and nuts which connects the support structures to the collectors for tightness.

✓ Heat transfer fluids. Anti freeze solutions in liquid solar heating collectors will have to be replaced periodically. And this right here is a task that’s best handled by a licensed technician.

Is there enough sun for solar panels in the UK?

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’ll work throughout the year.

Do solar panels require maintenance?

You shouldn’t need to maintain your solar panels much at all as long as there’s nothing piled up on top of the panels that could block out the sun. They are installed at an angle, so when it rains the water runs off them and gives them a clean. However, if this doesn’t quite cut it, you can spray them with a hose a few times a year.

How much do solar thermal panels cost?
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.
How does solar energy work?

Solar energy comes from the sun. Solar panels absorb sunlight, and convert it into electricity. This can be used to power heating systems, lighting and appliances. You can also get solar thermal systems, which use solar energy to warm hot water.

Solar energy is a type of renewable energy, because sunlight is considered to be in unlimited supply.

how many solar panels and batteries to power a house?

How Many Solar Panels And Batteries To Power A House?

Do you wish to know the number of solar panels and batteries sufficient for a house? Well, this is a frequently asked question in the solar world which would be very difficult to provide an accurate answer. This is basically down to the fact that all homes are unique with different sizes as well as amount of daily energy requirements. As a result, the number of solar panels and batteries needed would be unique to the house in question. However, we’ll consider the varying influencing factors that will go a long way to help calculate the number of panels and batteries needed to power a house.

First and foremost, let’s take a look at the solar panels. You’d have to start here by putting into consideration all household appliances that makes use of power in the house to get a good idea of how many that’ll be needed.

• How Many Watts Is Being Used In The House On A Daily Basis?

To determine this, simply go through your utility bill for kilowatt-hours (kWh). This varies amongst homes and being able to identify your daily average energy usage will assist you in getting your solar needs.

• What Is The Number Of The Peak Sunlight Hours At The House’s Location?

Having in mind that the solar panels only work when under direct sunlight, the first step to determine the peak sunlight hours. Once determined, you can then multiply the figure in hours by the house’s hourly energy usage and divide by the solar panel’s wattage.

Overall for a 1500 square foot house, the number of solar panels that’ll be required should fall around 15 to 18.

Meanwhile for batteries, there are also some factors to be considered to determine the number of batteries that is required to power a house. These factors include the house’s power or electricity usage, the period of time in which the battery will be used as well as the battery’ specifications.

How long do home solar batteries last?
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%.
