Why solar?

At Lindab we have combined our 60 years’ experience in sheet metal processing with the timeless looks of standing seam and the latest technologies in solar energy harvesting to bring you the Lindab SolarRoof.

We are bonding flexible thin-film solar cells with roofing sheets in our production, to keep high quality standards, reduce installation time and save costs for you. Panel level monitoring and performance optimisation is added, to get the most out of the solar cells. Everything is then connected together, secured against elements and the energy is fed into the house’s main board.

Our solar cells are made with the latest CIGS (Copper-Indium-Gallium-Selenide) technology in an integrated production process and feature high energy yield in all light conditions, superior light spectrum acceptance and high shading tolerance. Overall, they work longer hours during the day, even in Scandinavian climate conditions. The uniform black appearance makes them the perfect choice for high-end architectural applications or heritage conservation areas.

The optimizers installed up on the roof ensure maximum power output and control each panel individually, which means that even if some panels are covered or in shadow, the remaining ones will perform at their best. In the same time, you can have more solar panels on the same roof, on different roof slopes. The optimisers act also as a safety switch, cutting the DC from solar panels to a safe 1V, if needed.

Being a Lindab solution, it comes without saying that Lindab SolarRoof is fully compatible with our well-known rainwater system, roof safety systems and other roof accessories.

Why solar?

European Union has set itself an ambitious goal for 2050 to reduce greenhouse gas emissions by 85-90%, compared to 1990 levels!

Solar Energy

How solar works

Solar panels
When the sun rays (photons or particles of light) hit the solar cells it knocks electrons free from atoms which generates a flow of electricity. Solar panels consists of many solar cells that are connected to each other and by connecting the front and back of a solar cell, we are able to withdraw direct current from the solar cells. By connecting several solar panels into one string, you get a higher voltage.

Optimizer
An optimizer converts direct current to direct current while controlling the MPPT, this means that each optimizer can adapt individually to different conditions such as shading, angle and direction. An optimizer also monitors the panels and functions as a DC circuit breaker by only producing 1V when it is switched off (receives no signal from the inverter).
MPPT or Maximum power point tracking is a function of the inverter or optimizer where it is ensured that the solar panel always operates at maximum power. Since the solar panels do not always produce a constant voltage or current, this point must be constantly adjusted.

Inverter
An inverter helps turn the DC current produced by the solar panels into AC power. Besides that, the inverter has other functions such as security, monitoring and optimization. Traditional inverters also have built-in MPPT that is looking for optimum (global) point for the entire string and not the panels individually. Modern inverters with optimizers is instead looking for individual points based on each panel and not the whole string combined. Therefore, not all panels are affected when a panel becomes shaded or gets a defect.

Energy meter
The energy meter measures the amount of electricity that is being used by the customer. There are several different types of energy meters and the main difference between an old version is that the new versions measures energy flow in both directions and can calculate which electricity that is being consumed by the customer and which is sold to the grid.
The energy meter communicates with the utility company, which then automatically pays you for the sold electricity.

Grid
The grid is suitable to having a lot of micro production all over the network, the main advantage is that the energy loss in the grid is much lower when you are producing electricity and your neighbour or nearby industry consumes it then when the utility company has to transport it over long distances.

The active area of Lindab SolarRoof works well in low light condition and has a superior spectre acceptance since our cells are produced in CIGS technology. South facing slopes are best suited for active area installation, but east or west-facing slopes can have good performance, as well. Even though we have panel level control, it is preferable to have the roof area free from obstacles and shadowing, as it can influence overall production even if only individual panels are affected. When preparing the quote, we estimate how appropriate a roof area is and how much energy can be produced. Lindab SolarRoof is best suited for roof slopes of least 3.3m in length.

rerequisites

Step 2

Quotation

After Lindab has received a quotation request, a sales man contacts the tinsmith to collect the necessary information about the roof. Lindab has a template which is being used to ensure that the right information is collected. This is to make the buying process as smooth as possible.

The quotation is delivered in two stages, where the first step is a quote describing the content, the product and the pricing information.

When the quotation is approved, a complete specification of the plant's yearly production, a layout, complete technical manual is attached. The offer is exclusive of assembly and cost of electrical installation. The tinsmith delivers the quote and includes the cost of installation.

Step 3

Subsidy
application

Many countries have subsidies that apply to renewable energy sources and initiatives to produce green energy. This is often a yearly amount of money that is earmarked for specific installations; therefor it is better to apply for the subsidy in an early stage.

Step 4

Contact the
network owner

After approved offer, the end customer together with the electrician will contact the network owner, send them the necessary information, and make sure that specific regulation and rules are acknowledged before the installation begins.

The electrician can help with the contact of the network owner and usually you can handle it digitally via the web site owner's website.

Step 5

Sell excess
energy

In order for a utility company to buy the produced energy that is not consumed by the household, an agreement must be signed with the desired supplier. Contact your utility company to help ensure that the correct agreement and form are submitted.

Step 6

Delivery &
Assembly

Delivery of Lindab SolarRoof together with additional roofing panels. This arrives with accessories, the inverter and optimizers to the desired address. User-friendly manual, product datasheet, layout and checklist are enclosed with the delivery.

The tinsmith assembles the solar panels according to the manual and prepares with accessories and fasteners for the electrical installation. The tinsmith should not install any electrical components; however, the tinsmith can plug in and mount the optimizers if the electrician then approves the connections. This can be advantageous because then the tinsmith does not have to come back after the electrician has plugged in the optimizers, which are easily connected through quick connectors.

Step 7

Electrical
installation

The electric plug connects the solar panels and assembles cables to the position where the inverter is to be mounted. The inverter must be mounted and connected as instructed in the manual. Inverters and optimizers can be mounted outdoors and have a high efficiency and long warranty. The electrician does not need to connect any DC switch because the optimizers have that feature built-in. However, an AC switch is required between the inverter and the power supply.

In the power station, the inverter is simply connected to a separate fuse, which is connected between the main switch and the ground fault switch.

Step 8

Checklist

Before the network owner is advised about the completion of the installation, the checklist must be filled out. The checklist ensures that the installation is installed as directed and meets all safety and functional requirements. Thereafter, an announcement is made to the network owner that the installation is complete.

Step 9

Subsidy
approval

Submit a form that the installation is complete to the Administrative Board to get approval for the solar cell subsidy. Attach copies of invoices, certificate for the person(s) who has invoiced the work and the installation date.

Step 10

Follow-up

Once the plant is running, it will produce electricity for over 30 years. However, for optimal production, we recommend that you monitor the panels at regular intervals. Through a visual inspection as well as a quick check in the app, you will also get an indication of whether there is any panel that is dirty or has an error that needs to be fixed.
