Frequently Asked Questions (FAQs)
For Solar Panel System
Can your solar panels work well in Nordic countries?
Yes, solar cells work excellently in Norway and other Nordic countries and, in practice, perform even better in cold weather conditions. Solar cells do not need sunlight to produce electricity. As long as there is daylight for instance in cloudy, overcast, or even rainy weather conditions, the solar cells will produce electricity. The solar cells we use at our facilities are very efficient from February to November.
Can all roofs produce electricity from solar panels?
Yes, all roofs can produce electricity, but west and south-facing roofs will produce far more electricity than other roofs. Therefore, we mainly recommend installing solar cells on the part of your roof that produces the most electricity.
Do you have to change the roof to install solar panels and is there any benefit for the roof?
- No, it is not necessary to change the roof to install solar panels. If you are planning to change the roof, we strongly recommend installing solar panels at the same time, as you can save costs for scaffolding, roof coverings, and the like.
- Notably, solar panels can quickly and automatically clear snow from the roof, reduce the corrosion caused by wind and rain, and can effectively extend the lifespan of the roof.
Are solar panels safe?
Yes, solar cells are safe. They pose no additional risk in terms of, for example, the risk of fire compared to other electrical installations. All facilities that are installed will be reviewed by a certified installer to confirm compliance with municipal requirements.
Do solar panels require maintenance?
It's not mandatory as we offer the market's best solar panels that are completely maintenance-free, but we recommend checking the surface conditions once a year if possible.
How can we monitor solar electricity production and manage the misfunctions?
With us, you get access to an app where you can follow the electricity's production, deployment mode, operation management, and error monitoring from entire systems at any time. At the same time, we will also send you an alert and error elimination solution if any misfunction is monitored automatically.
How about the after-sales service you can provide?
- We have a local and global service network covering Nordic countries. it means local after-sale engineers and spare parts are available easily to serve you.
- You can contact us by phone or email Monday through Friday and you will get a response within two workdays.
How about warranties if we want you to provide a turnkey solution for solar panels?
- 25 years of solar panel power retention above 80% & 12 years for material
- 5 years for Inverters
- 3000/6000/more cycles & 80% DOD & 25°C (cycle life) for battery
- 10 years of mounting rack and accessories
- 10 years for installation.
How much subsidy from the government can we get?
- In Norway, you can get up to NOK32,500 of subsidy from Enova when you start producing electricity yourself with solar panels, and an extra NOK 10,000 of subsidy for an energy storage system.
How long can we get money back from our investment in solar panels?
- For residential, the pay-back time is estimated at 6-10 years depending on the roof conditions and complexity as well as the location.
- For C&I buildings, the pay-back time is estimated at 4-8 years depending on the roof conditions and complexity as well as the location and scale.
- For utility-scale parks, the pay-back time is estimated at 7-14 years depending on the land conditions, location, market pricing, and capacity.
How much solar electricity can we get if we install a 10kw of solar panels?
- Normally 10kw of solar panels in Norway can produce 8,000-10,000 kWh of electricity depending on the location, tilt angles, and variable weather.
What happens to surplus power?
If your system produces more electricity than you consume, you can either store the power in a battery or sell the power back to the grid company in the same market spot price.
Can solar panels increase the value of our house?
Solar cells have been investigated and shown to be able to increase the value of a house by up to 17%. Houses with solar panels are also sold up to 20% faster.
Can I order a complete package for the solar system from the manufacturer and install it by myself?
- Yes, you can. We not only sell solar panels, batteries, ESS, and mounting accessories to our distributors but also sell the package as a project developer to project owners.
- Although the solar kit we design and deliver to you features an absolutely simple assembly procedure. But just to be sure, we strongly recommend that you seek the help of a professional installer/certified electrician.
How about the delivery time?
Lead time: 20 days
Can your product comply with EU standards?
Absolutely yes, in terms of specific standards for each product, you can check it on our website or contact us for more details.
For Battery Energy Storage System (BESS)
Can I buy your BESS to adapt to my existing solar panel system?
- If you have installed solar photovoltaic panels before, our BESS is a good choice to adapt to your system;
- If you are a new user of solar energy, then we can provide you with solar photovoltaic panels, mounting brackets, power cables, and connectors along with BESS to assemble a complete system for you.
What is the value if I install solar panels combined with BESS?
- BESS can keep your solar system operating in place when your utility service is interrupted. Without energy storage, your PV system will be forced to shut down when the grid is off.
- BESS can enable you to use clean solar energy to power your home BOTH day and night to reduce on-grid energy dependence.
- BESS can store surplus solar energy and use it in less sunlight times.
- Peak-Valley electricity arbitrage.
- Back-up as UPS
Can I use BESS without solar panels?
- Absolutely. For on-grid clients, a home energy storage unit stores energy from your electricity provider. If an outage occurs, home energy storage can provide 24 hours and even more of potentially life-saving power. And, at the same time, BESS functions Peak-Valley power arbitrage. it can be automatically charged dropping in a low spot price period and power your house within a high spot price time.
What is a Lithium battery's lifespan?
- We provide a 10-year product warranty and guarantee up to 6000 cycles, whichever comes first.
Why choose Lithium Iron Phosphate over Lithium Ion batteries?
- We use Lithium Iron Phosphate (LiFePo4; Lithium Ferro Phosphate) technology – the safest lithium technology in the industry. It’s environmentally friendly and can be fully recycled. In comparison, many other competitors, such as LG Chem, Tesla, and Panasonic use cobalt-based Lithium-Ion battery, which has poor thermal stability. Any short circuit or cell breakage can cause thermal runaway and catch fire.
- At the same time, Lithium Iron Phosphate batteries deliver a substantially higher amount of life cycles. We guarantee up to 6000 cycles, while LG Chem, Tesla, and Panasonic provide less than 3000 cycles.
Are CEEG Lithium batteries widely compatible?
- Yes, our batteries are designed to work with all 48V chargers and hybrid inverters. We work well with Schneider, Outback, Magnum, Sol-Ark, Victron, Morningstar, and so on.
