Can solar panels be profitable if I have a heat pump or electric car?

Yes, solar panels are a particularly good investment if you have a heat pump, electric car, or other large electricity consumers in your household. The more electricity you use, the greater the savings when you produce your own electricity with solar panels. At EcoRay, an independent advisory solar panel platform, we use advanced technology, artificial intelligence, global data, and data-driven APIs to design tailor-made solar panel systems that match your consumption and maximize your financial gain. With our optimized solar panels, which deliver 30% higher production than previous estimates, and intelligent control, you can achieve a quick payback period and significant savings, especially if you have a heat pump or electric car. Here, we delve into why this combination is so strong and how EcoRay helps you get the most out of your investment.

Heat pump + solar panels: A strong combination

A heat pump typically uses 3,500–6,000 kWh per year, depending on your home's size, insulation, and heating needs. With a solar panel system and battery, you can cover a large part of this consumption, especially in spring, summer, and autumn when solar production is high. Here's what you can expect: Production with solar panels: A 10 kWp system produces 11,700–14,300 kWh annually (with 30% higher yield thanks to EcoRay's advanced UV-coated and light-sensitive panels). Self-consumption with battery: With a battery and intelligent control, you can use 60–75% of this electricity yourself, corresponding to 7,020–10,725 kWh annually. This covers a significant part of the heat pump's consumption, especially during the day and evening when the battery supplies stored electricity. Benefits: By using your own solar electricity for the heat pump, you reduce dependence on the grid and avoid high electricity prices. This results in a shorter payback period, lower heating costs, and a better indoor climate at a fraction of the price. With EcoRay's data-driven analyses, we ensure that your solar panel system and battery are sized to match the heat pump's consumption pattern, so you get maximum efficiency.

Electric car + solar panels: Faster payback

If you have an electric car, you typically use 2,500–5,000 kWh per year for charging, depending on driving patterns and car model. With solar panels, you can produce a large part of this electricity yourself, drastically reducing your charging costs: Intelligent charging: EcoRay's intelligent control systems can optimize charging so it occurs when the sun is shining or when electricity prices are lowest. With a battery, you can store surplus electricity from daytime and charge the car "for free" in the evening or at night. Production and savings: With a 10 kWp system, you can cover most of the electric car's electricity consumption, especially if you combine it with a battery and grid balancing. This means you can effectively run on solar energy for large parts of the year. Financial gain: The combination of solar panels and an electric car significantly shortens the payback period, often to 5–7 years, especially if the system is correctly sized and equipped with a battery.

Example: Household with heat pump and electric car

Let's look at a typical Danish household with both a heat pump and an electric car: Annual electricity consumption: 12,000 kWh (incl. 3,500–6,000 kWh for heat pump and 2,500–5,000 kWh for electric car). Solar panel system: 10 kWp with battery and grid balancing. Expected self-production: 11,700–14,300 kWh annually (with 30% higher yield). Self-consumption: With a battery, you can use 60–75% of the production yourself, corresponding to 7,020–10,725 kWh, which covers a large part of the heat pump and electric car consumption. Surplus electricity for sale: You sell 3,575–6,110 kWh to the grid at DKK 1.00–1.50 per kWh during peak periods, generating an annual income of DKK 3,575–9,165. Savings: You can save up to 70% on your electricity bill by using your own electricity, plus the income from selling surplus electricity. Payback period: With a battery and grid balancing, the payback period is typically 5–6 years, thanks to high electricity consumption and optimized control.

Why solar panels are a no-brainer with high electricity consumption

The more electricity you use, the more you can save with solar panels. Heat pumps and electric cars increase your electricity consumption but also make solar panels more economically attractive, as you can use a larger share of your self-produced electricity. With EcoRay's intelligent control and battery storage, you can: Maximize self-consumption: Use your solar electricity directly for the heat pump and electric car, reducing the need to buy expensive electricity from the grid. Optimize sales: Sell surplus electricity when electricity prices are highest, thanks to grid balancing. Shorten payback period: High consumption means your system pays for itself faster.
