How much electricity can I sell back to the grid in Denmark?

Selling surplus electricity from your solar panel system back to the grid is a fantastic way to maximize the value of your investment in solar energy. But how much electricity can you actually sell, and what does it mean for your finances? At EcoRay, an independent advisory solar panel platform, we use advanced technology, artificial intelligence, global data, and data-driven APIs to calculate precisely how much electricity you can sell and how to optimize your income. Factors such as your electricity consumption, system size, battery storage, and grid balancing play a crucial role. Here, we give you a detailed and transparent overview of what you can expect, based on realistic scenarios and a 30% higher production than previous estimates, with a focus on solutions with battery and grid balancing.

How much electricity can you sell?

The amount of electricity you can sell to the grid primarily depends on how much electricity your solar panel system produces and how much you use yourself in your home. With EcoRay's optimized solar panels, which deliver 30% higher yield, and our data-driven approach to designing your system, you can expect the following when using a battery and grid balancing:

Selling electricity with battery and grid balancing

With a battery and intelligent grid balancing, you can store surplus electricity for later use and sell electricity when prices are highest, e.g., during peak load periods. This increases both your self-sufficiency and your income. For a 10 kWp system, which produces 11,700–14,300 kWh annually (with 30% higher yield): Self-consumption: With a battery, you can use 60–75% of the produced electricity yourself, which corresponds to 7,020–10,725 kWh annually. Surplus electricity for sale: You thus sell 3,575–6,110 kWh annually to the grid. Sales price: With grid balancing, you can achieve DKK 1.00–1.50 per kWh during peak periods when the grid has the greatest need. Annual income: This provides an income of DKK 3,575–9,165 annually, depending on the amount and timing of the sale. Grid balancing makes it possible to sell electricity when prices are high, maximizing the value of your surplus electricity. At the same time, the battery reduces your need to buy electricity from the grid, further lowering your electricity bill.

Example of income

Here is an example for a 10 kWp system with a battery and grid balancing: With a battery and grid balancing, you sell electricity at a higher price, while also using more of your own electricity and saving on your electricity bill. EcoRay's data-driven calculations help you find the perfect balance between self-consumption and sales to maximize your financial gain.

Important factors to consider

To optimize how much electricity you can sell and how much you earn, you need to consider the following: Your electricity consumption: The less electricity you use yourself, the more you can sell to the grid. EcoRay analyzes your consumption pattern and designs a system that suits your needs. System size: A system that is correctly sized for your consumption plus a little extra ensures optimal production without waste. Our AI-driven analyses ensure that your system is perfectly adapted. Battery and intelligent control: A battery stores surplus electricity for use in the evening or on cloudy days, while grid balancing lets you sell electricity when prices are highest. Market prices: Electricity prices vary, and EcoRay's AI-driven analyses help you take advantage of the most profitable times for sales.
