Find a Solar Panel Installer you can trust near you.

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.

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.

Solar energy is renewable, as the sunlight it uses won’t run out. This means that it’s a great way to generate electricity without damaging the planet. So, installing solar panels to generate solar energy can be a great move for businesses looking to reduce their carbon emissions.

• The power of your solar panel system – there's no point buying a higher capacity battery if your system will never generate enough electricity to charge it
• How often you think you will need to charge your battery
• Your budget
• Whether you care about having the latest technology and a recognisable brand name

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

Just like other major house improvement projects, some specific requirements must be met to allow for the installation of solar panels on commercial buildings. The main reason why these standards and regulations were established is to minimize the risk of the solar system becoming an issue or potential hazard in the unforeseeable future. So if you’re thinking about buying and fitting new solar panels, you’ll probably want to know whether or not you’ll require to submit a planning permission application for approval before you can proceed.

Fortunately, the installation of solar panels on commercial buildings may be “permitted development which mean you won’t have to apply to the Local Planning Authority for planning permission. There are, however, some important limits and conditions which must be put into consideration in order to benefit from these permitted development rights. Some of the limitations include:

• The solar panels must be installed on a wall or pitched roof that should project at a maximum of 200mm from the surface of the wall or roof slope.
• Equipment placed on a roof should not be within one metre of the external edge of that roof.
• Equipment mounted on a wall must not be within one metre of a junction of that wall with another wall or with the roof of the building
• If the equipment is on the roof of a building, the capacity for generation of electricity across the entire site must not be more than 1 megawatt.
• In the situation whereby the panels are installed on a flat roof, the highest part of the equipment should not exceed one metre above the highest part of the roof.

In general, obtaining a planning permission is very important and as such, you must discuss your position with your chosen installation company before you proceed.

Are you thinking about installing a solar thermal system in your home? If yes, the you’d most likely be wondering the exact amount the system is going to cost. Well, you’re not alone. This is one of the most common question when it comes to solar thermal systems and we aim to answer that in this article. So let’s get started!

Unfortunately, the cost of a solar thermal system can’t be given in a single, accurate answer as they vary widely. However, when getting a new solar thermal system, you can expect to pay a sum within the range of £3000 to £6000 ( this includes a lowered VAT rate of 5 percent). The figures provided takes into account the installation costs as well as all the parts ( such as control panel, solar collectors, hot water tank and pipes).

To determine the price of your system, the quality and type of the panels matter. For instance, according to the Solar Trade Association, a properly insulated twin coil cylinder system would be priced at around £4500. in the same tone, it’s also possible to get DIY solar thermal kits that includes all the required hardware which will cost within the range of £1500 to £250. This however, may not be eligible for government support. In order to benefit from the RHI, your system must be fitted by a MCS accredited installer.

The varying prices of the solar thermal system’s initial cost is based on the specification of each individual house. For example, in situations where the building is having complicated water system, the plumbing cost is expected to increase which will have a serious impact on the overall cost of the solar thermal power system.
