Comparison of solar tariffs with a virtual battery
Iberdrola Solar: Solar tariff with a virtual battery
With Iberdrola’s virtual battery, any surplus energy you do not use is stored as a credit and applied to your subsequent bills, including the standing charge and other supply costs. Ideal for self-consumers who generate more than they use during the day.
Naturgy Solar with a virtual battery
Naturgy stores your surplus energy in a virtual battery so that you can make the most of it at night or during months when generation is lower. A solution to maximise the return on your solar installation without the need for physical batteries.

What is a solar tariff and how does it differ from a standard tariff?
A solar tariff is an electricity contract designed for homes with solar panels. As well as the price per kWh you consume from the grid, it includes compensation for surplus energy: the supplier either pays you or deducts the value of the energy you generate but do not consume. Choosing the right solar tariff can make a significant difference to how quickly you recoup the cost of your installation.
What is surplus compensation?
This is the mechanism by which your energy supplier deducts the value of the electricity your solar panels feed into the grid from your bill. There are two main types: simple offsetting, which deducts that amount up to the value of your consumption, and the virtual battery, which carries the balance forward for use at a later date. At QuéComparo, we compare both to see which is best for you based on your profile.
Which is better: simple compensation or a virtual battery?
It depends on how much you generate and when you use it. Simple net metering is more straightforward and is usually sufficient if your monthly consumption equals or exceeds what you generate. A virtual battery is worth considering when you produce significantly more than you use during the day, as it stores that surplus as a credit for the night, other months or even other supply sources. Our advisers will calculate this free of charge based on your specific situation.
What is the best solar tariff to make the most of my surplus energy?
There’s no single answer: the best solar tariff depends on your installation, your consumption and your energy supplier. Offers change constantly, so the best advice is to compare them and seek advice from independent professionals. At QuéComparo, we analyse all the self-consumption tariffs on the market to find the one that offers you the best value.
Can I switch to a solar tariff even if I already have solar panels installed?
Yes. Changing your tariff does not affect your solar installation or require any building work. It simply involves updating your contract with the new electricity supplier and the terms for surplus energy compensation. The process is free of charge and, in practice, takes just a few days; we take care of all the arrangements.
Do I need a specific energy supplier to have a virtual battery?
The virtual battery is offered by several energy suppliers (Iberdrola, Naturgy, Repsol and others), each with its own terms and conditions regarding how the credit is accrued and applied. Not all of them allow the credit to be used towards the standing charge or other services. It is therefore advisable to compare them before signing up.
How do I know how much energy I’m feeding into the grid?
Your surplus is shown on your bill, and you can also view it in the customer portal or on your energy supplier’s app. If you provide us with a recent bill, we’ll work out how much you’re feeding into the grid and which solar tariff would make the most of that surplus.
Is there a cost or a minimum contract period involved in switching to a solar tariff?
Switching energy suppliers is free of charge. Some tariffs have minimum contract periods or specific conditions, so before signing up, we check the small print to ensure there are no surprises. An ‘offer you can’t refuse’ sometimes hides conditions that aren’t in your best interests.
How do I switch to a solar tariff with QuéComparo.es?
Give us a call or leave us your details and an adviser will contact you free of charge. They will analyse your energy generation and consumption, recommend the solar tariff that offers you the best value at that time – regardless of the supplier – and take care of all the paperwork. Please have a recent bill to hand to speed up the process.
Is it worth reviewing my solar tariff every so often?
Yes. Energy suppliers are constantly updating their payment terms, and if your contract is more than one or two years old, it’s likely you’re no longer getting the best deal. Checking your solar tariff regularly is the best way to ensure you’re still getting the most out of your solar panels.
