What people ask before they buy
Will solar keep my lights on during a brownout?
Only if your system has a battery. Standard on-grid solar switches off when the grid goes down, for the safety of line workers. A hybrid system or an all-in-one backup unit keeps the circuits you choose running, like the ref, lights, fans and Wi-Fi.
How much will I actually save?
It depends mostly on how much power you use while the sun is up. Homes and businesses with daytime aircon or equipment save the most. The estimate gives you a starting number, and we confirm it from your bill and a site survey.
Can I sell extra power back to SOCOTECO II?
Systems up to 100 kW can apply for net metering. Power you send back to the grid is credited against your bill. We help prepare the application and the requirements.
What warranties do I get?
Panels, inverters and batteries each carry their own manufacturer warranty. We list every one in your quote, and if something fails, we handle the claim with the supplier for you.
Can I pay monthly?
Yes. We work with financing partners for homes and small businesses. Tick “monthly payment options” in the estimate or ask us on Messenger.
What do you need from me for a quote?
A recent electric bill (a phone photo is fine), a list of what you want running during a brownout, and photos of your roof if you have them.
