Put your house to work producing energy: a Solantra solar roof at a reasonable price
English translation of the original Estonian article. Original headline: Pane oma maja energiat tootma: Solantra päikesekatus mõistliku hinnaga
Who wouldn't want a warm home whose small electricity and heating bills always come as a pleasant surprise? Quite a lot can be done with quality insulation materials, but what if you produced electricity for the heating system yourself?
There are several ways to get electricity for your household, and one of the most popular recent solutions for private and commercial buildings has been the use of various solar energy systems. But what could be even better than being able to use solar panels as a roofing material?
A BIPV solution (Building-Integrated Photovoltaics), or solar roof, fulfils two functions: protecting the building while producing electricity at the same time. It consists of power-generating and non-active parts to give the roof a uniform appearance.
Solar roofs have been built for over 10 years and have become rather commonplace. The reasons are their aesthetic appearance and years of peace of mind if the right product and installation partner are chosen. Like any other roofing material, a solar roof is laid directly on the battens.
How does a solar roof differ from a conventional solution?
Conventional solar panels (PV)
- Installed on top of the existing roof covering or facade with a separate structure.
- Require a mounting system and additional sealing on top of the roof covering.
- Often affect the architectural appearance of the building (they look like a separate layer).
The main advantages of a solar roof
- Solantra solar panels are part of the building's roofing and/or facade material.
- They play two roles at once: roof covering and electricity production. There's no need for a double investment (separate roof + panels).
- No separate supporting structure or duplicate materials needed.
- Looks like an ordinary roof or facade.
- Long-term cost efficiency: the initial investment may be slightly higher, but savings are made on roofing material and separate mounting systems.
- Economy and sustainability: less material use and a smaller ecological footprint.
- Future property value: houses with BIPV are more modern, less dependent on the market price of electricity and more energy-efficient, which increases their market value.
The biggest benefit: in the long run, a solar roof helps save energy and money.
First, there is no need to buy "two roofs". In addition, if a battery bank is installed with the system, night-time and winter consumption can be made even cheaper. Second, producing solar energy makes it possible to earn personal income. An investment that pays for itself in the long run. The only roofing material that earns its money back.
A solar roof is highly resistant to changeable weather conditions.
- Solar roofs are designed to last: they withstand heavy Nordic snow loads and have been successfully tested even with hurricane-force winds.
- The Solantra solar roof is made of durable components that protect your home for decades.
- A maintenance-free solution: this roofing material doesn't need regular maintenance – rain and the natural environment keep the surfaces clean. So there are no additional expenses or time spent, making it one of the most convenient roofing materials of all.
Maintenance: how do you look after such a roof, and how much time does it take?
A solar roof is an almost maintenance-free solution, designed to last for decades without special care. Extra maintenance is only needed if the roof is under large trees or next to a gravel road. Then washing may be necessary to ensure maximum energy output.
Drawing on long experience, Voltamp OÜ offers the best solutions.
For over 10 years we have been working in construction and installing roofs and (solar) energy systems. We create complete solutions to ensure a home's energy efficiency and the durability of its roof. We offer buildings the following:
- Solantra solar roof: an integrated roofing material that produces electricity.
- Battery banks and energy storage.
- Roof renovation work.
- Installation and maintenance.
The Solantra solar energy system offered by Voltamp OÜ can also be combined with other roofing materials and is suitable for both new and renovated houses.
The Solantra solar roof is a completely new technical solution whose main features are:
- Very good water resistance.
- Installation from a roof pitch of 10°.
- Enhanced fire safety measures.
- High snow load resistance.
- Fast and simple installation – an innovative solution without mounting brackets or assembly gaps.
It is also good to note that there are no very high demands on the building. It is best to install the panels on a roof without too many recesses and penetrations. But by using composite panels, penetrations and recesses can also be covered, and every roof can get a strong covering.
Myths and reality: the profitability of an energy-producing roof.
There are many common myths about solar panels and solar roofs. Here we explain the background to some of them to give a clearer understanding.
You can't get electricity in dark or cloudy weather. A solar roof produces energy even in cloudy weather, but in smaller amounts. Since the system is connected to the grid, the necessary energy supply is always guaranteed at home. Installing batteries of course offers solutions. In addition, with the equipment offered by Voltamp OÜ you can take part in the frequency market and earn extra income from storing electricity.
In winter, snow limits the use of a solar roof. Output is naturally lower in the winter months, especially in December and January. From February, when the sun is already higher, the readings rise noticeably. Energy can also be produced through a thin layer of snow.
Solar roof prices are too high and the payback period long. The Solantra solar roofs offered by Voltamp OÜ combine roofing material and energy production into one. It is a cost-effective solution that will certainly pay for itself over the years and also earns the owner a steady income.
