We received the following quote for installation of solar panels and a battery. Our electricity consumption is 1821kWh for the last year. We don’t know much about these so not sure if it a good price or not. Any input will be very useful for us to decide. Thanks

Looks allot like the quotes I’m getting now.
8 panels of 500 wp will give you 4000 watts max (this is theoretical, in practical terms you usually never reach that theoretical limit). So this will largely cover your consumption + charging.
Keep in mind that battery is 5kwh and you roughly consume 4,9kwh per day on average based on what you told us. In winter these panels will never be able to charge the battery to it’s full charge, but in summer you should easily get there.
I have to say I think 1821kwh per year is not a very high consumption. You will need to change your energy consumption behaviour to use more of your own produced energy during the day (put dishwasher on/washing machine/…)
De prijs lijkt mij relatief OK voor wat het is maar stel mij wel zwaar vragen bij de kostprijs van een vaste batterij.
Marstek Venus E 5.12kWh plug in batterij = 1200€ op een goeie dag.
Solar quote looks right. Battery, mmhh. My advice: get two plug-in batteries (that should match the capacity you’re planning on) for half that price. If you realize you need more than 5kWH (which you probably will), you can add more. If you don’t need more, you’ve saved a bunch.
Quote van 2 jaar geleden, regio Antwerpen.
Zonnepanelen waren precies een pak goedkoper, maar de installatiekost was dan weer een pak hoger.

We recently got our battery. 21 kWh, 10kW inverter (10kW inverter allows us to draw 10 kW from batteries, for high peak currents when needed, aditional cost vs 8 kW inverter was minmal). 6 extra 500Wp panels. Total price was about 12k, iirc.
Very happy we got 21 kWh, we have pretty much not used a single kWh from the grid since installation, so easily saving 6-8 euros per day right now (fyi: heating is electric heatpump + ACs in bedrooms, so our energy use is as high as 30-40 kWh on bad days, easy). Will have to see how that evolves towards the winter.
The price is okay. But I’d personally never get a battery. The technology is not there yet. By the time it reimbursed itself (purely from electricity bills) it’s going to be decayed significantly. Depending on your very specific circumstances it can be an added value, or if you got it through e.g. a 0% loan from the government for these stuff, or get a payment help from the discount. Otherwise, investing is something else like a heatpump is a lot more interesting in my humble opinion.
I can’t find the power of the inverter in the quote. Am I missing something? If it’s not in there, definitely ask the installer before signing.
I think this is expensive, but it depends how much work it is for cabling, etc. I am a installer. Round prices for install should be a dead giveaway that not to much work went into the offer.
Seems expensive. Recently signed for solar panels and battery myself. Solar panels (4.6 kWp) was 2.7k. Inverter + battery + EMS(15 kwh) was 6.4k.
A battery is almost never worth it at current day prices. Get the panels, don’t get the battery.
In my opinion, it is not a bad price for the panels, but it’s really bad for the battery.
You can now get a plug and play battery from marstek that you can simply plug in any* of your sockets.
You can even buy it from Germany since there is 0% VAT on batteries = you should be able to get the battery for around 1000 euro.
FWIW I paid a bit more than that for 10 panels and a 10kWh battery, last year.
So the price looks good to me, or we both have been swindled 😉.
These 10 panels produced 4900kWh of electricity in a year, so the 8 you show should cover you (3900kWh, in proportion).
4900 is above what we consume as a household – but now we also charge the car, so this fits us, more or less. (Stupid calculation: an EV consumes ~20kWh/100km, so 10 000km is 2000kWh).
Those panels cost online €80 btw not included. Of course you need to pay transport and accessories, but still…
Did they explain to you why they want to install a 7.5 kWp inverter (SH5.0SR), while you have just 4 kWp worth of panels?
Damn wat een markup.. https://solago.be/products/ja-solar-500w-bifacial-glas-glas-full-black-jam60d41-lb-prijs-gestaffeld
I have a quote for 12 485 wp panels en a 5kva hybrid transformer for 3760€ all incl. Batteries where around 3000€, I can’t remember if they where 12 or15 kwh.

Battery looks very expansive. Normal prices now are 200 a 300 euro per kWh(I paid 4500 for 19kWh
Ik heb in 2021 3K betaald voor mijn batterij (11kw)
En 2K voor 12 panelen met 325 wp
Dus lijkt me realistische prijs
Lidl is selling 2.24 kwh battery pack suitable for solar for 299 euros 😀 Wtf is that?
terugverdientijd van die battery gaat serieus hoog zijn aan die prijs, als hij het haalt 🙂
voor dat bedrag zet je 2x Marstek Venus E 5kw en heb je geld over (wel enkel zinvol als je meer panelen hebt 😉 )
Ooit de vergelijking gemaakt hier tussen een hybride batterij en een marstek 5,12 , prijsverschil van 6800€ dat de hybride batterij duurder is . Na berekening kon ik de prijs van dat type er nooit uithalen dus voor een plug-in van Marstek gegaan en dat werkt echt heel goed . Dagelijks verbruik is 60% naar beneden gegaan en s’nachts ook 0, communicatie werkt via P1 meter en homewizard met abo 0,99 per maand .
Hij staat op 800W ingesteld en kan idd hoger maar let daarmee op . Hij kan enkel wat kuren hebben als de software een update nodig heeft maar dat is het dan ook.
Uw prijs lijkt me dan ook correct maar 4000€ voor de batterij vind ik persoonlijk nog steeds 1500 € teveel voor een 5,12 type .
Wij hebben recent een offerte ondertekend met gemiddelde prijs van 0,7€/Wp (dit is: 9300Wp zonnepanelen + omvormer 5kW + demontage bestaande installatie) en 330€/kWh aan vaste thuisbatterij (capaciteit 10kWh). Vooral jouw thuisbatterij lijkt me duur met 800€/kWh
Recent een artikel verschenen over kosten thuisbatterij met zelfde melding van +/-300€/kWh: [artikel](https://www.nieuwsblad.be/binnenland/prijs-van-thuisbatterijen-is-afgelopen-twee-jaar-gekelderd-voor-het-eerst-echt-rendabel-te-noemen/151795259.html?utm_medium=referral&utm_campaign=share)
Meanwhile my Marstek battery provides 5 kWh for 1k…
Vrij duur, ik heb in totaal 7850€ betaald voor 10 panelen (440w) +2 batterijen 5,1 kw + slimme sturing +installatie (plat dak) en keuring
It will take a very long time before you can make any profit from this at current conditions
