Taking the leap from conventional energy to renewable energy can be a wise decision for businesses that want to reduce operating budget expenses. Here, solar energy is the obvious solution, as solar panel systems can either be incorporated into new commercial construction or installed on the roofs of existing buildings.
The roof area of many older commercial buildings is not optimally utilized but instead lies unused. This is unfortunate, as solar panels for commercial use can save a company a lot of money, both in the short and long term. Admittedly, the cost of the system itself may seem like a large expense right now, but since the lifespan of a solar panel system is long and the payback period is relatively short, it won’t be many years before the investment will have paid for itself. Thereafter, all the energy that the system produces will be free.
In addition, energy prices have been steadily rising over the past several years due to fluctuating production costs, increased demand, dwindling reserves, and politically set tariffs – and there is no sign that this will change anytime soon. Commercial solar panels are therefore worth considering for companies, industries, and institutions that want to equip themselves for the future.
The roof area is an enormous resource, which at many companies and institutions remains untapped – and that’s a shame, as there are large amounts of renewable energy to be harvested from solar panels. Solar energy is an ideal energy solution for most types of commercial, thereby contributing to the green transition.
Worldwide, the green agenda has also long been in place, although we often talk more about overarching energy goals at a national level and less about what the individual company can actually do to push the development in the right direction.
For the same reason, it pays to invest in solar panel systems for a business, as they not only contribute to the green transition but can also boost the company’s CSR value.
CSR stands for Corporate Social Responsibility and is a popular concept covering companies’ responsibilities towards society, the community, and the environment. Good initiatives, such as investing in renewable energy, can create positive publicity, which can attract new customers and partners.
Every year, solar energy gains more and more ground in both the Danish and global energy markets – and with good reason. Modern solar panel systems have both long lifespans, short payback periods, and provide unlimited access to the sun’s enormous energy reserves.
Since 2002, the average amount of solar energy produced globally has increased by about 48 percent per year. This makes solar panels one of the fastest-growing energy technologies today – despite frequent predictions from established experts to the contrary. This strongly suggests that solar energy is not only here to stay but will also continue to pave the way for a greener world, where renewable energy forms can eventually replace conventional electricity and fossil fuels.
A solar panel is made of the semiconductor silicon, an element that occurs in the Earth’s crust and has many industrial applications. For comparison, a computer chip is also made of silicon. The electrical current can only go one way. This means that when energy is applied to the electrons of the material, they can only move in one direction (unlike, for example, metal, where the current goes both ways).
There is a large and demanding processing process behind when silicon is to be converted into solar panels, and this is the primary reason for the price of solar panels. A solar panel system is mostly characterized by its modular construction.
There is every reason for both companies and private individuals to seriously consider investing in solar energy as the next natural step toward a more sustainable future. But what is a solar panel system? How does it work? What does it cost? And what should one know before buying?
Fundamentally, a solar energy system can extract energy from the sun’s life-giving light. It is not the rays, but the light itself that activates the solar panels. Therefore, a solar panel system can still produce electricity when it’s cloudy – though to a lesser extent than when the sun is high in the sky.
Solar panel systems work by converting radiation energy into electricity through what is known as the photovoltaic effect. A solar panel primarily consists of the element silicon, which converts solar energy into direct current when light hits the panel’s surface.
The current can only move in one direction, as the solar panels function as a semiconductor. However, a solar panel system is also connected to an electric cable, which is linked to an inverter. The inverter converts the direct current from the solar panels into alternating current, which can then be used directly in the respective property or private home.
A well-functioning, modern solar panel system can convert about 20% of light energy into electricity. Solar energy is primarily generated during the day, but that does not mean the power disappears at night. A solar panel system is also connected to the public power grid, to which all excess electricity is sent – and from there, it can always be retrieved.
Aesthetically, it can be a challenge to establish solar panels so that they do not look like foreign objects and impair the building’s aesthetic expression.
Consideration must be given to the local plan in the area around the building where solar panels are installed. Is the building possibly protected, or are there other rules for how the building may/can look?
Theoretically, solar panels yield the most with a southward direction where an inclination of about 30-45 degrees is optimal. But in practice, the panels should follow the roof’s inclination to avoid extra wind and snow loads.
The panels can advantageously be placed edge to edge, so they do not cast a shadow on each other. Thus, the production per ft² of roof area is optimized, and the installation costs of the solar panel system are minimized.
The lifespan of solar panel systems depends on the supplier, efficiency, and quality. However, as a rule of thumb, you can expect 25-30 years once it has been installed.
However, it is likely that the inverter will need to be replaced “already” after 10-20 years, as it unfortunately does not last as long as the solar panels themselves.
In addition, the savings on the electricity bill will be noticeable immediately if the solar panels are mounted correctly and produce the optimal amount of energy.
Therefore, the payback period is relatively short – often, the system will have paid for itself in under 5 years.
The price of a system varies depending on size and supplier. However, it is sensible not to specifically go for the absolute cheapest solution on the market, as the price and quality of solar panels are inextricably linked.
The lifespan of a cheap solar panel system will often be shorter, and the system could end up being more expensive in the long run if it needs to be replaced too quickly. Typically, a more expensive system will also require less maintenance.
However, the price of solar panels is primarily determined by how many kilowatt-hours (kWh) it should be able to deliver – that is, the size of the system. The more kWh, the higher the price. The price of solar panels should be considered as the price per kWh produced. The price per produced kWh will be cheaper, the larger a system is established.
A small solar panel system can easily cost over $2 per watt, while a large system can come close to half per produced kWh (installation cost / annual expected production kWh = kWh price).
Simply put, a solar panel is a type of diode created to convert light into electricity via what is known as the photovoltaic effect. The solar panels receive power through the material’s electrons as soon as the sun’s rays hit the solar panels. When several solar panels are put together in plastic, glass, and an aluminum frame, it is called a solar panel.
Solar panels have a long lifespan and require virtually no maintenance.
Solar panels deliver renewable energy and are therefore a significant investment for our future. In addition, they are easy to install and integrate into buildings, and although it is an expensive investment upfront, it is the best and cheapest solution in the long run.
Monocrystalline solar panels are the most widespread type of solar panel, often appearing black. They are characterized by having a high theoretical efficiency and the best performance per square meter compared to other types.
