Solar Frequently Asked Questions
NRG Xperts’s licensed technicians answer frequently asked questions below. We aim to help you make the most informed decisions tailored to your property, budget, goals, and energy demands.
Here’s what our clients often want to know:
Is your property a good candidate for solar panels?
Many different property types, including residential solar sites, can be excellent candidates for solar energy systems.
Ideal properties receive consistent, unobstructed sunlight and minimal shading. They also have high or stable energy use and sufficient roof or ground space.
Do you need a permit to install a solar energy system?
You typically need one or more permits or approvals to install a solar panel array. These might include electrical permits for wiring and inverter connection, building permits for roof-mounted or structural work, zoning or land-use approvals for ground-mounted or scaled systems, and utility interconnection agreements to connect your system to the power grid.
What are the different types of solar arrays?
Common solar array types can be grid-tied or hybrids that combine panels, battery storage, and a grid connection. Panels can be roof, ground, or pole mounted, or integrated into your building’s initial construction. They can also be attached to solar tracking systems that follow the sun.
Each solar array type offers unique advantages depending on your site layout, budget, and energy production needs.
How will you know how many PV panels you need?
We offer a free solar assessment to help you calculate the number of PV panels you need for an appropriately sized system that meets your energy demands. Our technicians consider your monthly energy consumption, selected panel model efficiency, site-specific sunlight conditions, and available space.
How long does solar installation take?
Solar installation timelines vary depending on project size, scope, and complexity. We factor in our whole process, including design, permitting, utility approval, and installation, to give you as accurate a project turnaround time as possible.
Does your solar system need a battery?
That depends on your goals. Not all systems require batteries. You may consider solar storage solutions when you want to rely on your array for emergency power during outages.
How much does a solar panel system cost?
Solar panel system costs vary by size, location, and panel type. Some government incentives can help lessen upfront costs considerably. We can help you understand the financial options available to you.
Are there tax credits or rebates for solar installation?
In many regions, yes. Be sure to check government websites for information about the latest incentives, including tax credits and rebates, from the Federal to the municipal levels. We can also give you tax credit information during a consultation.
Can your solar panels fully eliminate your electrical bill?
With the right system size and setup, you can do just that. In some areas, you can even make money by selling your energy overages back to the grid.
How long do solar panels last?
Most panels last between 25 and 30 years and may perform longer. Regular maintenance is the secret to capturing the most energy savings.
How much maintenance do solar panels require?
Solar panels require very little maintenance. An annual inspection and cleaning are usually enough, alongside the odd targeted repair. However, some systems may be subject to compliance requirements that dictate specific maintenance and inspection intervals.
Do photovoltaic panels work on cloudy days or in the winter?
Yes, while solar production is lower during overcast days and winter months, your system will continue to generate power year-round. A properly sized system accounts for seasonal variation and ensures consistent performance across all seasons.
Will solar panels damage your roof?
They won’t when installed correctly. Proper installation, using industry-approved mounting systems and flashing, prevents leaks and keeps your rooftop intact.
Can you monitor your solar energy setup remotely?
Yes, modern systems have online monitoring platforms or mobile apps that empower solar system tracking from anywhere.
