Sell your solar panels' surplus energy to us

Q: How much does selling solar energy pay?

Usually electricity companies pay for solar energy the hourly rate of the Finnish market in the Nord Pool power exchange (spot-price). Companies may add their own transfer comission and / or a basic fee. At Hehku we pay for microproducion the spot price with a deduction of our margin, and it'll show for you as a deduction of your electricity bill.

Q: Who can I sell my surplus energy to?

You can sell your surplus energy to any energy company that buys it. Many energy suppliers in Finland also buy surplus electricity from households' solar panels – including Hehku. Usually you'll need to have your regular energy contract in the same company that you want to sell your surplus energy to.

Q: Do I have to pay taxes on my surplus energy production?

In theory yes, but in practice no. Energy generation is a taxable income, but the energy generation by solar panels in households is small-scale. This way, it doesn't reach the minimum tax treshold.

Q: Do I need extra setup to sell my surplus energy to the grid?

Usually no. If your house has solar panels, they're usually installed in a way that you can sell your surplus energy to the electricity grid without extra work.

Q: Is selling solar energy profitable?

There's no one simple answer. Usually energy produced by solar panels is used for that building's electricity and only the surplus is sold. Generally, selling surplus solar energy became more acquainted in 2022. Electricity prices also skyrocketed in 2022, which made selling surplus solar energy more profitable. In 2023 the prices returned to a more reasonable level.

When your solar panels produce more energy than you can use, sell the surplus to us. You don't need a contract with the electricity network – just a regular energy contract with us.

For surplus solar energy, we pay the hourly rate of the Finnish market in the Nord Pool power exchange (so called spot price). You can track the prices hourly on Nord Pool's website.

We only deduct our commission of 0.31 c/kWh (incl. VAT 25,5%). That's it – no monthly fees or sign-up costs.

How do I sell my solar panels' surplus energy to the grid?

To sell you excess energy production to the electricity network, you need to consider two things:

your solar panels have to be connected to the network
you need a sales agreement with your energy retailer (the company that you buy your energy from)

The energy produced by the panels is measured hourly and you're compensated accordingly. Usually your energy company either reimburses the rate on your electricity bill or debits it to your bank account once a year.
