Used straight away
Every kWh the house uses while the roof is producing is a kWh you don’t buy. This is the biggest part of the saving, so a pool pump or washing machine running at noon pays.

What the sun pays you
Three questions about your house, and an honest estimate in euros. The free study makes it exact.

An estimate, not an offer. Assumed: €0.30 per kWh bought, €0.12 credited for each kWh sent out under net billing, 1,650 kWh a year from each kW of panels. A battery moves about 80% of the daytime surplus into the evening.
Where the saving comes from
Stored or credited
What the house can’t use at noon either charges the battery for the evening, or goes to the grid and comes back as credit on the next EAC bill. A battery is worth more under net billing, where credit is lower than the price you pay.
What people ask us
How much will I really save?
It depends on how much you use and when. A house that runs air conditioning and a pool pump through the day saves the most. The free study turns your last bills into a figure in euros before you decide anything.
Net metering or net billing: which is mine?
Net metering sets every kWh you make against one you use. Net billing settles production and use each billing period and credits the surplus to your next bill. Which one is open to you depends on the size of the system and EAC’s current rules; we prepare the application either way.
Do I need a battery?
Not always. A battery pays when you use most power in the evening, or when you want lights and fridge on in a power cut. Without one, a net metering system still works. We show both versions in the study.
Will it work on my roof?
We fit tiled roofs, flat concrete slabs, metal sandwich panels and ground frames. Shade from trees or a neighbour’s building matters more than the roof type; we check it from your photos and on site.
Can I see what the system is doing?
Yes. Your client account shows output, use and savings in euros, live and by bill, and alerts us if output drops.
