Solar Panel Installer FAQs

how many solar panels can i fit commercial buildings?

Are you currently weighting the possibilities of adding a solar system to your commercial building? With lots of commercial property owners in the UK using solar now, many more are gradually coming to terms with the numerous benefits they stand to derive by getting one. Therefore, if you’re thinking about adding the system to your commercial building but do not know where to start, you’ve come to the right place.

 

In this post, our aim is to help you calculate the number of solar panels you’ll need to power your entire commercial building. Starting from the panels, you can begin by taking into account everything that makes use of power in your commercial building to get a good idea of how many you’ll need.

  • To get started, you’ll have to determine the number of watts used by your commercial building. To get this, you simply have to go through your utility bill for kilowatt-hours (kWh). This varies amongst buildings and being able to identify your daily average energy usage will assist you in getting your solar panel needs.
  • Once done, you’ll also have to determine the peak sunlight hours - having in mind that the solar panels only work when under direct sunlight. Once determined, you can then multiply the figure in hours by your home’s hourly energy usage and divide by your selected solar panel’s wattage.

 

In general, a medium-sized commercial building making use of an average amount of electricity will require about 70 average quality solar panels so as to cover its entire electricity needs. These are, however, just averages, so yours could be more or less so getting the idea is vital here.

How do I test my solar panel?

If you want to test your solar panel system to see if it’s working properly or just to see what output it’s giving, you can do this using a multimeter to measure current, or amps, and voltage.

Before you start, you’ll need to find the voltage (v) and current (A) ratings of your panel. You should be able to find them on the back of the panel. You should also make sure that it’s a nice clear, sunny day to get the best readings out of your panel. You should also check that it’s safe to be up on your roof!

To measure open circuit voltage, you’ll need to make sure that your solar panel is completely disconnected from your system’s regulator and battery (if you have one). Angle the panel towards the sun, and ensure that your multimeter is set to measure volts. Measure the voltage between the positive and negative terminals by connecting the negative contact on the voltmeter to the negative on the panel and the positive contact on the voltmeter to the positive on the panel.

Then, you can move on to the short circuit current. Follow the same steps as the open circuit voltage, but ensure that your multimeter is set at 10A to start with.

Only try to test your solar panel if it’s safe to do so. If your roof isn’t accessible without scaffolding or specialist equipment, consider speaking to an MCS-registered solar company about your concerns. They may recommend that they come to service your solar panel system.

How do solar thermal panels work?

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.

how long does it take to install commercial solar panels?

After making the very important business decision to go solar, you may also want to know just how long it’ll take to complete the installation process and start generating electricity. After all, generating electricity is the main reason you made the switch to solar system. In this post, we’re going to provide you with in depth details on how long it takes to install solar panels as well as the factors that may affect that time.

 

The entire process of solar panels installation and getting them approved isn’t an overnight process. You’ll have to wait for periods for each step of the process whereby one must be completed before moving to the next. The time required to complete each step can, however, vary largely depending on your location, the type of solar panels you opt for, the solar company you hire as well as the number of people that’ll be making the installation. Here are the steps to a solar system installation and the estimated time each are expected to take:

  • Site assessment. Once you chosen your solar company, the first step would be to have a solar professional from the company to visit the site to examine the roof and other features so as to make sure that they’re able to support a solar system. From the initial contact to scheduling the site visit, this step can take up to 1 to 2 weeks
  • Local permitting. This involves getting the right permits from your local authorities. This can take up to 3 to 6 or more weeks.
  • Solar system design. This may take up to a week or two depending on whether or not you need design approval and also where the parts are coming from
  • Installation. This step can take a week or two depending on the size af your solar panel and roof.
  • Inspection. This step can take up to a week depending on where you reside and how quickly the inspector can visit.
  • Utility connection. Depending on your utility company, this step can take up to 2 weeks.
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%.
Are solar panel batteries worth it?

Whether solar panel batteries are worth it depends on how much you’re at home and how big your solar panel system is. If you’re at home most of the day and your solar panels only generate enough electricity for you to use while for that day, then a battery probably isn’t worth investing in. However, if you have a large system that generates more than you can use or you’re out most of the day, then solar panel batteries are definitely worth it.

A solar battery storage system works by storing the electricity that your solar panels generated until you need to use it. That’s why they’re great for people that are out all day – your solar panels generate electricity all day whilst the sun’s out, but no one’s home so you’re using minimal energy except for things like your fridge and any appliances on standby. Most of the electricity charges your solar panel battery. Then, when you get home, your battery will discharge, and you’ll use all the solar electricity that your panels generated during the day.

Solar batteries are also excellent for people with large solar panel systems that generate more than they use in the day. Any electricity that you don’t use during the day will charge the battery, so in the evening when the sun goes down, you’ll just use the excess electricity that’s stored in the battery.

To work out whether solar panel batteries are worth it for you, you’ll need to work out how much of your solar electricity you’re using already. If you’re at home and you’re able to run your appliances all while your solar panels are generating electricity, a battery might not be worth it. Also, if you’re receiving export payments from the Feed-in Tariff Scheme (FITs) or the Smart Export Guarantee (SEG), you might want to look at the rate you’re getting paid. If it’s a good rate, it might be more cost-effective to continue exporting unused electricity to the grid. Speak to an MCS-registered installer that will be able to help you work this out.

How do solar panels work?

Solar PV panels work by converting sunlight into electricity. They’re made up of photovoltaic cells, which take in the sun’s rays and turn it into direct current (DC) electricity. The current is then channelled into an inverter, which converts it to alternating current (AC).

Once converted to AC, the electricity is ready to use. It’s fed through a meter and into your property’s consumer unit, and is automatically used to power appliances and heating systems. Your system will automatically switch between your solar electricity supply and the national grid, and export any solar electricity you don’t use to the national grid.

Can I buy solar panels?
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.
