How a home can pay up to 90 % less on its electricity bill

When we say a household can pay up to 90 % less on its electricity bill, the first thing people think is: “inflated marketing”. Understandable. But the figure is real and it’s built by adding three levers almost no one uses together.

Lever 1 — Solar self-consumption (50-70 % less on its own)

The well-known one. A 4-6 kWp installation in an average home generates between 6,000 and 9,000 kWh per year, against a typical consumption of 4,000-5,000 kWh. The question isn’t to generate, it’s to consume what you generate:

• Washer, dishwasher and water heater shifted to sunny hours = immediate savings.
• Surpluses fed to the grid with bill compensation (covers a good part of nighttime consumption).
• Without batteries you’re already at 50 % to 70 % of net savings.

Lever 2 — Heat pump (the other 20 %)

This is the part most people don’t tell. Climate control and domestic hot water are usually 40-50 % of a household’s total energy bill, and they’re almost always paid in natural gas, butane or diesel oil (not electricity).

Replacing boiler + water heater with a heat pump:

• Reduces energy consumption by 70-75 % (COP 4 = 1 kWh electric → 4 kWh thermal).
• Eliminates the gas bill entirely.
• Works with your photovoltaic: the sun that’s left over heats the hot water and the heating’s inertia.

Added to solar self-consumption, we’re now talking 80-85 % overall savings on the home’s energy cost (electrical + gas).

Lever 3 — Indexed tariff + smart scheduling (the final 5-10 %)

The last trick is not paying for the little you still buy from the grid:

• Time-of-use tariff (3 periods): the rest you do consume at night falls to €0.05-0.08/kWh in off-peak.
• Smart scheduling of the home (heat pump charging thermal inertia off-peak, hot-water recirculator only in strategic windows).

Why isn’t it standard then?

Because almost no one integrates the three levers at once. Those who put up solar usually keep the gas boiler. Those who switch to heat pump don’t always pair it with photovoltaic. And almost no one reviews the tariff afterwards.

At AUREQIS what we do is design the complete system from day one: we measure your real bill, size you solar + heat pump + backup tariff, and show you the projected savings month by month before you sign anything.

The most important thing: doing it without a down payment

If you finance it via leasing, you don’t have to touch your savings: the monthly leasing fee is lower than the savings generated, so you pay less than now from the first month. And at the end of the contract the installation is yours.
