Frequently Asked Solar Questions

FAQ’s answering questions related to solar panels, savings, and how solar works.


What happens with my system when I go on vacation?

If you choose to go with a Solar Lease monthly, Solar Lease prepaid with monthly payments or Solar Loan, you will pay the regular monthly payment.

Will I save money by going solar?

Many Nexerium customers save up to 20%** on a yearly basis with a  Solar Lease Monthly or Solar Lease Prepaid . Monthly savings will fluctuate due to weather, length of month, and the amount of energy used in your home. Results vary for Solar Purchase and Solar Loan customers.

How much money can I save by going solar?**

Today, many Nexerium customers pay up to 20% less than their current utility rate**. Three factors affect when you will save with our solar plans:

1) How many panels your home will qualify for

2) How much electricity your household uses

3) Your current utility rate

When you purchase a system of your own, other factors affect your potential savings. We can help you evaluate those factors after we conduct a site survey at your home.

Aren’t solar panels expensive?*

Not necessarily. At Nexerium, we install the solar panels at little to no upfront cost, and our Solar Lease Monthly or Solar Lease Prepaid customers typically buy electricity from us at a lower rate* than their utilities. We also sell systems at competitive prices, and have relationships that can help you finance the purchase.

What’s the difference between solar power and other forms of energy production?

Solar power is energy that comes from the sun, while many other forms of energy come from fossil fuels (coal, petroleum, and natural gas). Both can be used to power your home, but they are generated differently. Energy from fossil fuels goes through multiple steps before reaching your home, including step-up transformers, transmission substations, and distribution substations. Solar power is collected by panels on your roof, then immediately converted into usable energy.

How long will it take to get the solar energy system turned on after installation?

Getting permission to operate a system and start generating energy largely depends on your local city and utility company. We will be able to give you a better idea of your operating timeline after your system installation.

Will solar panels work in overcast climates?

Yes, but performance may be affected. Solar panels produce more energy when the sun is shining.

What determines whether my home is a good candidate for solar?

We conduct an on-site survey to determine if your home is compatible for solar. Here are some examples of what we evaluate to make sure that solar is a good fit:

  • Roof size, pitch and direction
  • Shading of the roof caused by tree branches, other homes, etc.
  • Roof obstructions such as chimneys, pipes, etc.
  • Roof stability and strength
  • Electrical wiring
Are Nexerium customers connected to the grid?

Yes. Nexerium uses “on-grid” systems, meaning that they are still connected to the electrical grid. On-grid solar energy systems are necessary to transfer excess power into the grid, which can result in a credit to customers in some states. On-grid systems also keep you connected to the grid for additional power from the utility.


What happens if I move?

If you are a Solar Lease customer, our Transfers team will guide and support you through the system transfer process. The team can be reached by calling (+98) 912 1830 831, or by emailing

If you are a Solar Loan customer, you should work with your specific financing party to get the best assistance.


What happens to the solar panels at the end of the contract?

You have a few options once your contract is up. If you are a Solar Lease customer, you can renew your contract for an additional five years, purchase the solar system for fair market value, or request that the system be removed (at no additional cost). If you are a Solar Loan or Solar Purchase customer, your contract with Nexerium ends when the system is installed and operational.

What is the warranty on the solar energy system and how long will it last?

Our warranty guarantees our work will be free from material defects for 10 years, the system’s solar panels carry a 20-year linear performance warranty, and inverters carry minimum 10-year manufacturers’ warranties.

How many watts per hour will a panel produce?

There are many factors that affect the production of a solar panel (location, orientation, tilt, weather, season, shade, etc.). Solar panels produce varying amounts of energy through the day. In the mornings and evenings, when the sun is low in the sky, solar panels will generate less power than in the afternoon when they are receiving direct sun exposure.

Will solar panels cause my roof to deteriorate?

No. Our solar panels are not attached directly to your roof, but rather to a racking system that has been wind, water, and fire tested to ensure no leaks or damage will occur. Additionally, shingles on your roof will often last longer under installed panels because they are less exposed to UV light.

Do the solar panels degrade over time?

Yes, slightly. Due to sun exposure, weather and other environmental factors, there’s a potential degradation rate of 2.5% the first year the panels are on your roof, and 0.7% per year during the rest of the 20 year term. Most of our panels degrade at a rate lower than this, but we guarantee that they won’t degrade more than the above amount.

How much does a solar panel weigh and how big are solar panels?

The average panel used in a Nexerium installation weighs 18 kg and is 65 x 40 x 1.5 inches big.

Does Nexerium use microinverters or string inverters?

We use both.

Do the panels still operate when there are power outages?

No. In a power outage, our systems automatically shut off for the safety of the workers that repair the power lines.
