You are comparing solar energy storage quotes and the name Sigenergy keeps coming up. Except that one quote mentions SigenStor, another a Sigenergy hybrid inverter, and a third a « plug and play » battery from the same brand. It is difficult to know whether you are being offered three different products or three names for the same thing.

These are not three names for the same thing. Sigenergy is a brand, not a product — and behind the brand is an entire range. SigenStor is only one part of it, albeit the best-known one. Before pricing anything, the right approach is to place each product within the ecosystem, then see which one matches your needs.

That is exactly what this page does: it provides an overview of the Sigenergy brand and its prices in 2026, with a table by product range and a simple way to guide your choice. For details of a specific product — especially SigenStor — we will direct you to the dedicated guides.

You have probably already typed “6000W solar kit” into a comparison tool, only to come away with ten configurations that look identical in the photos but vary in price by as much as twofold. Central or hybrid inverter, with or without a battery, single-phase or three-phase: behind the same 6000-watt figure lie installations with different uses, efficiency levels and returns on investment.

This guide will not explain self-consumption all over again. It will answer the only question that really determines your purchase: is a 6000W self-consumption solar kit suitable for your household, and if so, which one?

We start with your consumption, not the datasheet. This is the only way to avoid paying for kWh that you will see exported to the grid at a low price.

Key takeaway: the amounts of photovoltaic subsidies (self-consumption bonus, surplus feed-in tariff, VAT rate) are revised regularly, often every quarter. Always

You have had an installation quoted and the quotation comes to several thousand euros. This is usually when you start wondering what the state actually reimburses — and come across a jumble of bonuses, feed-in tariffs and VAT rates that do not all apply to the same project.

Sorting it all out is not that complicated. In 2026, state aid for solar panels rests on three pillars: the self-consumption bonus, the feed-in tariff for surplus electricity, and reduced VAT. MaPrimeRénov' and local aid may sometimes be added, but these are special cases. We review each scheme one by one: who is eligible, how much you can receive, and the order in which to complete the necessary steps.

Key takeaway: the amounts quoted correspond to the scales published by the Energy Regulation Commission (CRE), provided as a reference framework. They are revised every quarter. Always check the value in force on the date of your

You have decided to go solar, you request two quotes, and then doubt sets in: 6 kW or 9 kW? One seems a little too small, the other a little too expensive. And no one clearly tells you which one fits your home.

It is the most important decision in the entire project, and it is also the one most often decided backwards. Consider the common reflex: choose the largest option «for peace of mind». The problem is that targeting 9 kWp when you consume 6 means tying up several thousand euros to produce a surplus that you will sell for next to nothing. Conversely, staying with 6 kWp when you have a heat pump and an electric car means letting savings slip away — all the more painful since electricity prices rose sharply between 2022 and 2024.

The right level is therefore not a question of power in absolute terms. It is a question of your profile: what you consume, at what time, and under which roof. Let us see how to make the right decision.

Key takeaway

Your panels produce power in the middle of the day — precisely when nobody is home. In the evening, when everything switches on, you buy that same electricity back from the grid at a premium price. This is exactly the mismatch that a 3000W self-consumption solar kit with battery is designed to correct — and this is where it is easy to get lost in watts, kWp and profitability promises.

The 3 kWp system is now one of the most popular formats among French households. Powerful enough to cover a significant share of a home's consumption. Compact enough to remain affordable and, very often, suitable for DIY installation.

This guide gets straight to the point. How much does a 3000W kit really produce, what is the battery for, how should the system be sized, how much does it cost in 2026 and which models are reliable. The goal: buy the right kit the first time, without having to pay again in two years.
