What our customers say.
★★★★★
„I asked for three quotes; SolarBay was the only one that sized to our consumption, not the roof. Everything was up in two days and I never had to deal with the DSO.”
L. FarkasGyál, 6.2 kWp + 10 kWh
★★★★★
„Precise, clean work; the shading around the chimney was solved with optimisers. The app shows we now pay a third of last year’s bill.”
A. VargaDunakeszi, 4.8 kWp
★★★★★
„They designed the heat pump and the solar together and it really works together: even in winter we heat mostly from our own electricity. Fair, reachable team.”
K. HorváthBudaörs, heat pump + 8 kWp
Frequently asked questions
How much does a solar system cost in 2026?
A 5 kWp residential system is HUF 2.2–2.6M turnkey; with a 10 kWh battery HUF 4.5–5.5M. Exact pricing follows a free survey as an itemised quote.
What is the payback period?
7–12 years depending on self-consumption and tariff scheme; considerably faster with a hybrid system, the grant, a heat pump or an EV.
What about the end of net metering?
New systems fall under gross metering: exported electricity is bought at a lower price. That is why we size for self-consumption and recommend hybrid systems where justified.
Can I order from the shop without installation?
Yes, every product can be ordered on its own. If you need installation, the quote lists labour and permitting separately.
Where do you operate?
Budapest and Pest county with our own crews, the rest of Hungary via partner installers – design and warranty always remain ours.
What warranty do you provide?
10-year workmanship warranty, 12–15-year product and 25–30-year performance warranty on panels, 10 years on inverters (extendable).
