What are solar panels?
Solar panels are designed to absorb the sun’s rays and convert them into electricity. A panel is made up of a number of solar cells that, when working together, create enough energy to be useful. The more light that hits a cell, the more electricity the panel will produce.
How do solar panels save businesses money?
The most immediate, and perhaps biggest way that solar panels can save your business money, is through an instant reduction in electricity bills. The amount you save depends on the size of your installation, the electrical load of your building and the price you pay per khh.
How long does it take for solar panels to become cost effective?
The time in which it takes a solar panel installation to become cost effective depends on a number of different factors including the size of the installation, the amount you pay for your business’ electricity and the base load of the building. There are numerous things that can be done to reduce the amount of time it takes for solar installations to become cost effective however; the main being having them cleaned and maintained professionally when required.
How many solar panels should I invest in for my business?
The number of solar panels you should invest in for your business depends on a number of things including your power needs and size of the roof. The first thing you need to determine when making this decision is what your solar centred goals are. Are you investing in solar panels because you want to reduce your carbon footprint, or because you want to save money, or perhaps it is because you want to maximise your ROI? Once you have the answer to this question, things may become clearer – most business’ priority is to save as much money as possible. To decipher your solar panel needs you must calculate how much power your business is using, the usable surface area of your roof and the peak sunlight and climate in your area. A professional solar installer will be able to help you establish how many panels are the right number for your needs.
Why should I have my solar panels cleaned?
The more light that hits your solar panels, the more power they will generate. Simple. Therefore, if you do not have your panels cleaned, and they develop shadowing from bird droppings and general dust and dirt, less light will be absorbed by your panels. As soon as light is being blocked by shadowing in your solar panels, you are losing ROI on your initial installation investment.
How many UK businesses have invested in solar panels to date?
Only 400 commercial scale (100kWp or larger) solar PV systems have been installed out of around 1.8 million commercial buildings in the UK. Yet across the whole of continental Europe, almost a third solar panels are installed on commercial roofs.
How do I know my solar panels need cleaning?
There are a couple of ways you will be able to tell that your solar panels need cleaning. The first is that all panels need to be maintained to always be working to their full potential. Therefore, it is not necessarily a question of ‘do my panels need cleaning?’ but rather, ‘when?’ We cannot stress enough that as soon as there is any shading on your panels, their efficiency will begin to reduce; you may be able to see the dirt itself on the panels, or notice an increase in your electricity bills. To find out how often your solar panels should be cleaned, please see the next question.
How often should solar panels be cleaned?
A dirty solar panel can decrease power output by 20%, but the frequency of which they should be cleaned can depend on four main factors. How often it rains, the tilt angle of your panels, the amount of wind-blown dust and your electric rate. We are happy to come and have a look at your array to advise on a cleaning and maintenance schedule.
How can I reduce shading on my solar panels?
Having a bird wire system fitted on your roof will reduce shading from soiling and effective ground maintenance will control overgrown trees and plants that may be casting shadows on your panels. Ultimately, having your solar panels professionally cleaned and maintained will reduce shading and therefore increase efficiency. For more information on this, please visit our contact us page.
How long do solar panels last?
Solar panels have no moving parts and because of this, are very reliable and require very little maintenance (apart from cleaning of course!) Some solar manufacturers offer a 30-year warranty on their panels, with the average falling to around 25 years.
What ongoing servicing and maintenance do my solar panels need?
At least a couple of times a year, your solar panels should be inspected for any dirt or debris that may collect on them. This inspection will then determine when and how often they need to be professionally cleaned.
What is solar PV?
PV is short for photovoltaic. Photovoltaic cells is the name that scientists use to refer to solar cells.
What does an inverter do?
A power inverter is an electronic device that changes direct current to alternating current. The input voltage, output voltage, the frequency and overall power handling depend on the design of the specific device.
What happens if my solar panels are producing more energy than my business is using?
If your solar panels are producing more energy than your establishment requires, the excess energy will be sold back to the grid.
