The Supersola has a 300 Wattpeak solar panel. This means that on average the Supersola will produce 264kWh a year in Dutch weather conditions, when placed facing south and with no shadow during the day on the solar panel. This is enough to power a washing machine and vacuum cleaner. This means you no longer have to buy this kilowatthours from you energy provider.

CO2 SavingsIcoon CO2-besparing

A Supersola saves around 171 kg of CO2 a year, compared to electricity produced from coal. This means that it wil save an impressive amount of 4.283 kg of CO2 in it 25 year lifetime. Which is similair to driving 35.995 kilometers with a car you would buy nowadays (2019). Also the Dutch foundation for nature and environment (Natuur & Milieu) has researched that within 3 years it has saved the same amount of energy that was needed during production. Since a solar panel has a lifetime of 25 years minimal, it means that every kilowatthour in the remaining 22 years are pure profit for the environment.

Subsidies in the Netherlands
Icoon subsidie

There is no national subsidy anymore for solar panels in the Netherlands. Sometimes there are some regional subsidies available form your province or municipality. Take a look at Energiesubsidiewijzer for an overview of local subsidies in your town. 

Besides subsidies you can also claim the tax return on the purchase price, when you register yourself as small enterpreneur. This means you can get a 21% tax return on the total price. On the dutch website of Milieu Centraal you can find a describtion on how to do this. Or you can order a tax return service to do it for you, if you do not want the hassle. These services can be aquired from €89 and can be lucrative from two panels or more.

What means salderen?

Salderen is regulation ment to stimulate the adoption of solar energy in the Netherlands for consumers. It means you can sell the kilowatthours you generate can be sold to your energy provider for the exact same price as you would pay for a kilowatthour. More simply put, your energy bills lowers with every kilowatthour you return to the grid. This principle can be applied to the amount of energy you would consume on a yearly basis. 


You use 2.000 kilowatthours(kWh) a year and feed 1.000 kWh back to the grid. A kWh will cost €0.22 on average at the moment in the Netherlands. This means that you would normally have to pay 2.000*€0,22=€440,- to your energy supplier. But because you return 1.000 kWh to the grid you energy bill also lowers with 1.000*€0,22=€220. This means that at the end of the year you no longer pay €440, but €440-€220=€220 for your energy bill.  

What does it mean to become a netto energy supplier?

When you feed in more energy to the grid the you would need on a yearly basis, you become a netto energy supplier. When this happens, salderen no longer applies for every kWh you produce more than you need on a yearly basis. An energy provider than is required to pay a reasonable compensation per kilowatthour. Which in practice will be around 6 or 7 cents per kilowatthour. The purchase price of a kilowatthour without all the taxes. Some energy providers will give a higher feedin tarif, because the want to stimulate solar energy. Therefore it can be worth the effort to pay attion to this tariff when selecting a new energy provider.


You use 2.000 kilowatthours (kWh) a year, but produce 2.500 kWh a year. That means you will have an electricity bill of zero (2.000 kWh bought from your energy provider, but also feeded in 2.000kWh), and also receive a compensation for  2.500-2.000=500 kWh. However these 500 kWh will only recieve a compensation of circa €0,06 to €0,11 per kWh. So instead of recieving 500*€0,22=€110, you will recieve 500*€0,06=€30. 

But because this compensation is nearly 75% to 50% less than you would receive for a kilowatthour under the salderen regulation. It wil mean that your return on investment will be much longer on all the solar panels you bought and produce more energy than you require on a yearly basis.
