Choosing the right solar solution for you.

You have a lot of options to consider when choosing a renewable energy solution.  Here are some Frequently Asked Questions (FAQ’s) from our Gretna solar panel company to help you sort out all the information.

Solar energy is a renewable energy source that harnesses the sun’s rays to generate electricity or heat.

Solar panels convert sunlight into electricity using photovoltaic (PV) cells. The electricity from these solar panels is then sent to your Gretna home or business, reducing your reliance on traditional fossil fuels.

While the initial cost of solar energy can be high, the long-term savings and benefits can be significant. In fact, solar energy can save you up to $1,000 per year on your energy bills.

Solar panels typically last for 25 years or more, with some lasting up to 30 years. They are also low maintenance and require minimal upkeep.

While solar panels can be installed on most Gretna roofs, they require a certain amount of space and a south-facing orientation to receive the most sunlight. Additionally, roofs with shading issues or severe weather conditions may not be suitable for solar panels.

Yes, solar panels can still generate electricity during the winter months, although the amount of electricity generated will be lower due to the shorter days and less intense sunlight.

In many areas, you can sell excess energy generated by your solar panels back to the utility company through a program called net metering.

Solar panels are designed to be safe and do not emit any harmful radiation or toxins. They are also UL (Underwriters Laboratories) certified, which means they meet rigorous safety standards.

While it’s technically possible to install solar panels yourself, it’s highly recommended to hire a professional solar installer to ensure proper installation and maximize the efficiency of your system. Our solar panel consultants in Gretna are happy to discuss options for your home.

Yes, most solar panel manufacturers offer a warranty on their products, which typically covers defects and performance issues for 25 years or more.
In general, solar panels can still generate electricity even when the grid is down, but there are some limitations and considerations to keep in mind. Here’s what you need to know:
 
Grid-Tied Systems:
Most residential solar panels are installed with grid-tied systems, which means they’re connected to the grid and can feed excess energy back into the grid. When the grid is down, these systems will automatically shut off to prevent backfeeding power into the grid, which can be dangerous for utility workers and others. This means you won’t be able to use the energy your solar panels are producing during a grid outage.
 
Grid-Tied Systems with Battery Backup:
Some newer solar panel systems, known as grid-tied systems with battery backup (also called “hybrid” or “grid-hybrid” systems), can store excess energy generated by your solar panels in a battery bank. This way, you can still use the stored energy when the grid is down. However, these systems typically require a separate battery bank and an inverter specifically designed for grid-tied systems with battery backup.
 
Off-Grid Systems:
If you’re interested in using your solar panels to generate electricity even when the grid is down, you’ll need to install an off-grid system. Off-grid systems are designed to operate independently of the grid and typically include a battery bank, an inverter, and a charge controller. These systems can provide power during outages, but they require a larger upfront investment and may require additional maintenance.
 
Key Considerations:
1. Safety
Always prioritize safety when working with electrical systems.
 
2. System Design
The design of your solar panel system will impact its ability to operate during a grid outage. If you’re unsure about your system’s capabilities, consult with our local Gretna professional solar installer or electrician.
 
3. Battery Life
If you choose to install a battery bank for energy storage, be aware that battery life will be affected by the number of cycles it’s used for backup power during outages.
 
4. Cost
Off-grid systems and grid-tied systems with battery backup are generally more expensive than traditional grid-tied systems.
 
In summary, while solar panels can still generate electricity during a grid outage, you’ll need to consider the type of system you have installed and whether it’s designed to operate independently of the grid. If you’re interested in using your solar panels to provide power during outages, consult with a professional solar installer or electrician to determine the best solution for your specific situation and learn about solar energy costs in Gretna.
