Having a partner to guide you through the process can make all the difference. We’ve answered your most frequently asked questions below.
How Do Solar Panels Work?
STEP 1: Sunlight Activates the Solar Panels:
Each solar panel comprises a layer of silicon cells, a metal frame, a glass casing, and wiring. During the daytime, the solar cells absorb sunlight.
STEP 2: Solar Cells Produce Electrical Current:
Each solar cell contains a thin semiconductor wafer made from two silicon layers. When sunlight strikes a solar cell, it creates a direct electrical current (DC).
STEP 3: Conversion of Electric Energy:
We need alternate current (AC) to run homes or buildings. So, DC needs to be converted into AC with the help of an inverter. Modern solar systems have one inverter for the entire system attached behind the panels.
STEP 4: Give Powers to Your Home or Building:
Once the conversion of DC to AC completes, the electricity runs through your electrical panel to power your home appliances.

What exactly is solar energy?
Solar energy is the radiant light and heat emitted by the sun, which can be harnessed and converted into usable forms of energy for electricity and heat. It’s a sustainable and renewable source of energy that reduces greenhouse gas emissions, making it environmentally friendly.
Can you explain the science behind how solar panels work?
Solar panels contain cells of semiconductive material, typically silicon. When sunlight strikes these cells, it excites electrons, causing them to move. This movement generates an electric current, which is harnessed to produce electricity.
What kind of solar panels do you sell?
As a solar dealer, we work with multiple installers and can offer a variety of solar panel options from the market. We only deal in Tier 1 products that are quality and backed by the best warranties. Most of the panels offered today are the (BOB) Black on Black higher wattage, higher efficiency modules. Because of our unique business model, we have the ability to access many more options than most sellers and therefore you’re guaranteed to get the best value.
Are solar panels worth the investment?
Whether solar panels are worth the investment or not depends upon various factors like location, energy consumption, incentives, upfront cost, and more. But, if you live in an area where utility bills are high, or you face power cuts, then investing in solar panels is worth it. Also, installing solar panels is a long-term investment and eco-friendly solution for generating energy.
What is Net Metering and how does it work?
Net Metering is a policy that makes it possible to get the most out of your solar system. In most states, Net Metering policies ensure that for every kilowatt hour (each unit of electricity) that you deliver to the electric grid, you will receive a credit for that kilowatt hour (kWh). So, if your solar system produces 100 kWh of energy, and you only use 60 kWh, that extra 40 kWh is sent back to the grid to share with your neighbors. The next time you need more electricity than your solar system is generating, you can use the 40 kWh credits you have at no charge. That’s Net Metering in a nutshell.
The reason why Net metering is so important is that solar systems produce energy during the daytime, but you use energy during the nighttime as well. When you’re out of the house during the day, you’re banking all the credits your solar panels produce. Then at night or on a cloudy day, you can cash in on all that energy you delivered to the grid and use the credits you accumulated.
That’s net metering. It’s an amazing policy. One that has enabled the solar industry to grow and, in effect, gives you the ability to use the grid as your own battery, reducing the cost of electricity for you and your family.
What is a feed-in tariff?
When your solar panels generate more electricity than you’re using, the overflow will either go into your battery or, if your battery is full or you don’t have a battery, will be fed into the main grid. Your energy retailer will pay you for this additional electricity, and this payment is called the feed-in tariff. In markets where Net Metering is not available the feed-in tariff is a buy back from the utility company. The value of the buy back depends on the utility and can often be negotiated or you can switch utility providers to receive the most advantageous feed-in tariff.
Am I selling electricity back to the grid?
Yes. If your solar system has more capacity than your home or business’ demand, and your utility has a Net Metering or feed-in tariff (buyback) program, you will receive credit from your utility during the late spring and summer, though the details vary between jurisdictions. If you generate more electricity than you can use in one billing period, the excess is banked and can be used in a future billing period. With net-metering, if you produce more than you consume on an annual basis you will be paid out for the remaining kWh in your bank at the wholesale rate.
Will solar panels still provide power when the grid goes down or power goes out?
No, while your solar panels continue to absorb sunlight and produce electricity, you will not be able to use that electricity during a power outage unless you have invested in a battery backup system. Grid-tie inverters are designed to shut down automatically upon loss of utility supply, for safety reasons. They do not provide backup power during utility outages. The inverter requires power to operate as well so they only work in conjunction with a battery storage solution.
Do I need a battery back-up storage system?
That depends on the market you are in and if Net Metering is available. Markets like California have lost the benefits of Net Metering in April 2023 and now the only way solar is economical is if they self consume what they produce by including a battery into their system. If you do not have Net Metering but have a favorable feed-in tariff then you may not need a battery system for self consumption either. If you are interested in emergency preparedness then you will want to consider a battery backup system as your PV system will not work in the event of a grid disruption without a battery storage system. Battery storage is evolving quickly and becoming more affordable and mainstream in the solar eco system. If you decide to invest in a battery storage system with your solar panels to be able to essentially be energy independent of the grid, it is eligible for the 30% federal tax credit.
How do you know if the system is working properly?
It’s easy. All of the solar energy systems we sell come with remote monitoring so both you and our installers can see how much energy your system is producing. This allows you to identify if there is a problem but most likely the installer will notice before you and be reaching out to schedule a service call.
What happens if there is snow on solar panels?
Snow can’t stick to solar panels for long due to their structure and installation angle. To maximize sun exposure, our staff install solar arrays at an angle. So, their steep angle and slick glass surface don’t allow snow to stick to them for long.
Will solar panels generate electricity on cloudy or rainy days?
Solar panels will stop generating electricity at night but will still generate electricity on cloudy or rainy days, just not as much as on sunny days. To create electricity, your solar panels need direct sunlight, so whilst it doesn’t need to be a bright sunny day all the time, the more sun that hits your panels, the more electricity is produced.
Will my solar panels stand up to hail?
Yes, solar panels are manufacturer rated for impacts from golf ball sized hail and larger. One typical rating is for a 55 mile per hour impact of a one inch diameter hail stone at a 90 degree angle. While extreme weather events can damage panels, the upward facing surfaces are made of tempered glass and are generally facing south if possible, and at an angle that would refract the falling angle of the hailstones.
Solar installations can be added to home insurance policies to protect a homeowner’s investment from damage.
Does roof orientation matter?
Yes, the orientation of your solar panels will make a difference to the amount of electricity produced. A southerly orientation is best, but your solar installer will look at the orientation of your roof and place the panels in the best locations to maximize the production of electricity on your property.
How much money can I expect to save on my bills?
This depends on a number of factors that include how much electricity your system produces, its efficiency, how much electricity you use, where you live, and the rate you are charged by your electricity provider. Our professional solar consultants will be able to give you a thorough understanding of that after simply reviewing your energy utility bill and developing an appropriate design for your home at no cost.
What happens to solar panels when it rains?
Solar panels are designed to withstand harsh weather conditions. And, during rain, the home solar system continues to generate electricity. However, the amount of electricity your solar panels generate may decrease depending on the cloud coverage or intensity of rain. But solar backup batteries can power the house during heavy rain without any issue. The good news is that when it rains, mother nature is giving your panels a nice thorough cleaning so when the sun comes out you can receive optimal performance.
Can solar power run an air conditioner?
es, solar power can run air conditioners in your home or building. But, you need to install the right number of solar panels based on your requirement to run one, two, or more air conditioners in your home. We can assess your energy requirement to help you with the best decision for installing the right number of solar panels for your home.
How long do solar panels last?
Through specific details, grading, and specifications, a typical solar panel is warrantied to produce for 25 to 30 years. Since the conductive material slowly degrades over time, it will still operate, producing less power than before.
The majority of solar panels in use today have been in use for less than 20 years, which means an accurate life can be estimated in the coming years. We generally set the expected life of solar panels to stay on the roof is about 30 to 35 years.
Can solar panels really save me money?
Yes, with solar panels, you may save in the long term. By generating your own electricity from sunlight, you can decrease or eliminate your utility bills. The savings also depends on factors such as your energy consumption, location, available incentives, and installation cost.
How do solar leases and power purchase agreements (PPAs) work?
Both options allow homeowners to benefit from solar energy without buying the system. With a lease, you rent the system and use the energy it produces. With a PPA, you pay for the electricity the system produces, usually at a reduced rate.
What incentives are available for installing solar panels?
Solar is a cleaner and more sustainable option than fossil fuels, and this is why governments offer various incentives for solar panels to encourage their adoption. These programs include solar rebates, tax credits, solar renewable energy credits (SREC’S), subsidies, low-interest loans, etc. You can contact us to get detailed information on this based on your location and state.
What happens to solar power when batteries are full?
When solar batteries are fully charged, extra solar power generated by them gets redirected according to the system’s configuration. In grid-tied solar systems, the excess power can be fed back into the electrical grid, and you may also get credits from the grid company. In off-grid scenarios, surplus energy could be wasted unless there are diversion loads or backup methods to utilize it.
How much does a solar power system cost?
A typical residential solar system can cost anywhere from $10,000 to $30,000 and beyond, but the entire process is custom designed and varies for every customer, business or family. The cost of a solar PV system generally depends on the amount of your typical electricity consumption, the age and design of your home or building, and your goals in terms of electrical energy production.
Our solar specialists are equipped to provide some baseline estimates and information at any time, so contact us to start the consultation process.
How long will it take for my solar system to pay for itself?
The “payback period” varies but is typically between 6-10 years. This depends on installation costs, local electricity rates, local solar incentives, and the system’s energy production.
What are my solar financing options?
Homeowners who are unable to pay the full price in one installment for solar installations can opt for financing options. These options include a variety of solar loan options, solar leases and PPAs. We can help you find the best financing option for your solar system needs.

What is better, buying, leasing or PPA?
If a homeowner can take advantage of the Federal Tax Credits, most homeowners find that buying a solar panel system is more beneficial than leasing. There are many financing options available, most of which offer $0 down just like a lease or PPA. Depending on the current interest rates, often, the monthly payment on a loan is lower than the monthly payment on a lease or PPA. Plus, buying allows you to take advantage of the federal Investment Tax Credit (ITC), which was extended in 2022 at 30% until 2032. Buying can also increase the value of your home and simplify the sales process if you decide to move. If a homeowner cannot utilize the benefits of the Federal Tax Credit or they do not qualify for the loan or want to carry a loan, a lease or PPA can be a great alternative.
What type of warranty do you offer?
We stand behind our products and services and back your solar energy system with a 30-year warranty that covers everything from maintenance to installation.
Is there maintenance involved?
There is little to no maintenance involved with solar panels. They are extremely durable and should last at least 35 years. Mother Nature typically looks after the maintenance with an occasional rain. The only thing you may need to do is rinse your panels clean of dust and dirt with a garden hose a couple times a year if Mother Nature is not being generous. Do not use any chemicals other than gentle dish soap and be careful to use a soft cloth if you scrub the modules. Solar panels are glass and can scratch which will refract the light and affect the performance of your system.
Can solar panels create hot water?
Some people get confused about solar power, thinking that it can also create hot water. While the electricity generated by your solar panels can be used to run your electric hot water system, your solar system itself won’t be heating water directly. If you’re after a hot water system, check out a solar hot water system or a heat pump hot water system.
Will solar panels increase the value of my home?
Yes, installing solar panels on your roof will generally increase the value of your property. Many buyers look for properties that already have solar power installed, because they can pay lower electricity bills immediately without installing the panels themselves.

How can I be sure that solar is a good investment for my specific property?
A detailed on-site assessment by our team will provide insights into potential energy production, cost savings, and financial benefits for your particular property.
How long do solar panels last?
Though specific details and numbers depend on manufacturer specifications, a typical solar panel warranty guarantees that it will produce 85% of its rated power production 25 years after it goes into use. Since the conductive material slowly degrades over time, it will still operate, but it will produce less power than it did before. The majority of solar panels in use today have been in use less than 20 years, which means we will only be getting an accurate picture of solar’s end of life in the coming years. That said, the expectation we generally set for customers is to expect the panels to stay on the roof for 30 to 35 years.
What factors impact the energy output of my solar system?
Several factors influence this: the efficiency and type of solar panels, the angle and direction of sunlight, potential obstructions or shading, and the system’s age.
How do seasonal changes affect solar energy production?
Solar production varies with seasons. During longer summer days, more sunlight is available for your panels to convert into energy, whereas winter months with shorter days yield less energy.
Does solar make financial sense if electricity is cheap in my area?
Even if electricity is currently cheap, solar can be a hedge against future energy price increases. Additionally, by taking advantage of tax credits, rebates, and other incentives, the cost of installation can be significantly reduced.
How does the solar panel installation process affect my roof’s integrity?
A professional installation will not compromise your roof’s integrity. Installers ensure that the mounting system is correctly anchored and sealed to prevent leaks.
How does going solar help the environment?
Solar panels help the environment because solar power is a renewable resource. Solar power lets you use the sun to power your home, which is a renewable, sustainable and environmentally friendly form of energy.
Improves Local Air Quality:
One of the biggest benefits of solar energy is that it results in very few air pollutants. An analysis by the National Renewable Energy Laboratory (NREL) found that widespread solar adoption can significantly reduce nitrous oxides, sulfur dioxide, and particulate matter emissions, all of which can cause health problems. NREL found that, among other health benefits, solar power results in fewer cases of chronic bronchitis, respiratory and cardiovascular problems, and lost workdays related to health issues.
Reduces Carbon Footprint:
The term ‘carbon footprint’ is used to account for the release of greenhouse gases, primarily carbon dioxide, into the atmosphere by human activity. The major contributor towards carbon footprint is the use of fossil fuels. Alternatively, solar energy is one of the cleanest forms of energy. For every 1 megawatt-hour (MWh) of solar energy produced, 0.5 to 1 ton of carbon dioxide is offset.
Lowers Consumption of Fossil Fuels
We have always largely depended on coal, oil and natural gas for our energy needs. Fossil fuels are finite in nature and cannot keep up with the increasing demand of energy and are major contributors for pollution. Solar energy, on the other hand, is abundant and can be endlessly harnessed to meet global energy consumption, reduce energy costs and ensure a stable energy future.
