Installing solar panels on your roof is currently one of the fastest and most effective ways to reduce your electricity bill. Combined with energy storage, property owners can optimize their own consumption and gain long-term control over their energy costs.

The roof as a long-term asset
With solar energy on your roof, you can reduce your property’s energy costs, strengthen its sustainability profile, and at the same time generate a stable, long-term return.
Solar power on roofs is now a given investment. The challenge is rarely the technology – but rather building an optimized system. That’s why you need a partner who takes overall responsibility and ensures that the solution is right, both technically and commercially.
Customized solar power for every property
Every property has unique conditions. The roof construction, electricity usage, tenant structure, and future plans affect both the design and profitability.
Alstra Energy analyzes the whole picture and designs solar cell installations that are optimized for your specific property – with a focus on maximum self-consumption, long service life, and reliable operation.


Profitability, climate benefits, and happier tenants
By producing your own local electricity, you can:
– Strengthen the long-term value of your property
– Reduce purchased electricity and protect yourself against future price increases
– Improve your property’s environmental rating and climate performance
– Offer tenants green, locally produced electricity
One partner throughout the entire process
We take responsibility every step of the way – from business analysis and preliminary studies to construction, follow-up, and ongoing management. With experience from some of Sweden’s largest roof installations, we know what it takes to build facilities that last 30–40 years and deliver stable production over time.

Amplify your investment with energy storage
By supplementing your solar cell installation with a battery, you can take the next step in optimizing your property’s energy system. A battery makes it possible to store surplus electricity from solar production and use it when the need is greatest – instead of feeding the electricity into the grid at a lower value.
The result is higher self-consumption, reduced power consumption from the grid, and more consistent energy costs over time. For property owners, this means better control over energy flows and an investment that strengthens both profitability and resilience.
Battery storage also creates opportunities for future business, such as flexibility services, peak shaving, and increased preparedness in the event of power grid disruptions. Together with solar energy, the battery becomes a central part of a modern, smart, and long-term sustainable property energy system.

Solar cells for industry and business
For businesses, there are many benefits to installing solar panels. Often there are large roofs available that are not currently being used. The return comes directly in the form of lower electricity costs and, in addition, each square meter of solar panels helps to reduce carbon dioxide emissions by 65 kg per year.
Solar cells for real estate companies
Often, real estate companies have several roofs that are not used efficiently, and there is money to be made here. One or more photovoltaic installations not only contribute to a better environment and thus a higher environmental rating of the property, it is also a concrete profitable investment. By producing your own electricity, you can cover your own costs, but also offer tenants green, locally produced electricity.

Why solar energy on the roof?
Profitable
The payback is immediate in the form of lower electricity bills. Self-consumption of solar electricity means that you do not have to buy electricity and save on the cost of electricity, but also on the variable network charge and any energy tax. Many make a profit in the first year.
Environmentally friendly
From a wider perspective, solar power producers are part of a global movement where microgeneration is part of a sustainable society with a clear vision for the future. At the same time, solar energy is the cheapest and fastest to build.
Independence
With solar panels on the roof, you will always have access to locally produced electricity and can feel independent of the electricity companies’ electricity price increases in the future. At the same time, battery and charging solutions are constantly being developed for those who want to supplement their systems.
Improve your energy rating with solar cells
Did you know that solar cells can improve your property’s energy rating, which in turn can increase its value? An energy rating is a summary of a building’s energy consumption and is carried out by a certified energy expert on behalf of the property owner. The result is an energy rating between A and G, where A represents the lowest energy consumption. The measurement takes a number of different parameters into account, including how much energy is used for heating, tap water, and property electricity.
Self-generated solar electricity consumed in your own property can be credited in the energy declaration and can give the property a better energy rating. This is a good way to reduce your costs for purchased electricity while increasing the value of your property.
