Solar systems produce electricity all year round, even on gray winter days. But most of the production takes place in the summer, where around 75% of the annual production is located. With a correctly dimensioned solar cell system, you can achieve a very high degree of self-sufficiency in the summer.

Yes, as a rule, a solar system will increase the value of your house, and here are three reasons why:

• It significantly reduces annual electricity costs.
• It can improve the house’s energy label.
• The solar system sends a signal that the property is green and sustainable.

It is not recommended to invest in a solar system that produces more power than the expected consumption. It is important to think about the future, for example with an electric car. Today, most buildings in Denmark are equipped with an intelligent electricity meter, which continuously informs the electricity company about the amount of electricity delivered to the building. In this way, you can monitor your power consumption and see when the most power is used. The previous consumption can usually be seen by logging in to your electricity bill at the utility company.

The maximum production of solar cells is measured in kWp (kilo watt peak) and represents the maximum amount of electricity the solar cells can generate under optimal solar conditions. Actual output varies with seasons, sun position and losses in lines and inverters. The actual number of kWh (kilo watt hours/hours) may vary from the expected due to these factors. The production capacity and actual production may be randomly close to each other.

A hybrid solar system consists of both solar cells and a battery, which stores the excess power generated by the solar cells. The battery can then be used to supply the household with electricity when the sun has set and the solar cells are no longer producing electricity. In Denmark, electricity consumption is typically highest between 17-21, where the electricity price is also high. Another important advantage of batteries is that you can charge the battery with cheap electricity at night and use it when the electricity is very expensive in the middle of the day.

A lithium battery is a type of rechargeable battery that uses lithium as the primary chemical component of its electrolyte. Lithium is a light and reactive metal that enables the battery to have a high energy density and long life. Lithium batteries are used today in a variety of products, including laptops, smartphones, electric cars and solar panels. They are popular due to their low weight, high energy density and ability to hold current for a long time without losing capacity.
