Frequently asked questions
About panels and batteries, how we work, what happens at the technical visit, and what the estimated price means.
Panels and batteries
- Is solar worth it in Romania?
- For many homes, yes. In Romania one kW of panels produces between 1,150 and 1,350 kWh a year on average, depending on the region. What you save depends on your bill, your roof and how much electricity you use during the day. The calculator shows an estimate for your address.
- What size do I need?
- We offer 6, 8 and 10 kW systems. The calculator suggests one from your monthly bill. At the technical visit the installer checks that it fits on your roof.
- Do I need a battery?
- Not necessarily. Without a battery you use the power as it is made during the day, and the rest goes to the grid. With a battery you keep some of it for the evening, when use is usually higher. A battery makes most sense if you are out during the day.
- I already have panels. Can I add only a battery?
- Yes. In the calculator, choose "I already have panels" to see battery packages for an existing system. At the visit the installer checks that your inverter can work with the battery.
- Do panels work in winter or when it's cloudy?
- Yes, but they produce less. Most of a year's production comes in spring and summer.
- What is a prosumer?
- A prosumer makes electricity and sends what they don't use to the grid. Your energy supplier counts the electricity you send and credits it on your bill, under the rules in force.
How we work
- Why can't I see prices on the site?
- Prices depend on your area and the installers who work there. You see them in the calculator, after you give us your address and confirm your phone number with a code by SMS.
- Why do you ask for my phone number?
- So we can contact you about the technical visit. The SMS code confirms that the number is yours. We don't sell your details.
- Will several companies call me?
- No. Your request goes to one installer who works in your area. You don't get a list of companies, and five installers don't call you.
- Who installs the system?
- A partner installer who works in your area and offers the package you chose. The CasaSolar colleague who contacts you chooses them for your request.
- How long until the installation?
- We don't promise dates on the site. After you send your request, we will reach out to you shortly to agree the day of the technical visit.
The technical visit
- What happens at the technical visit?
- Someone from the installer comes to your home and checks the roof, the electrical panel and the place for the inverter and battery. They note any extra work needed.
- How do I choose the day of the visit?
- In the calculator you pick the days you can be at home, in the morning (08–12) or the afternoon (12–18). A CasaSolar colleague contacts you to agree the day together.
- Do I need to be at home?
- Yes, you or someone who can let the installer in. They need to reach the roof, sometimes the attic, and the electrical panel.
Prices and estimates
- Is the price in the calculator an offer?
- No. It is an estimated price for the package you chose, worked out before anyone has seen the house. The price you sign is the one in the final quote, after the technical visit.
- Can the price change after the visit?
- Yes, if the visit finds extra work, such as a new electrical panel or a special roof mounting. It appears in the final quote as separate lines, each with its price. You decide whether to sign.
- Are the production and savings in the calculator certain?
- No. They are estimates from your address, your bill and the average production in your area. Real production depends on the roof, shade and the weather.
