Have Questions About Going Solar?
Solar 101
Batteries for solar systems act like storage units, storing excess solar power for later use. During the day, they store surplus energy that your home doesn’t use immediately. This stored energy is then used at night or during low sunlight periods. This cycle of storing and using energy is known as charge-discharge. It’s important to note that while most batteries are used for self-consumption, backup batteries are designed specifically to reserve a percentage of power for emergencies. These backup-capable batteries ensure your home stays powered during blackouts or other unforeseen events.
Your roof’s suitability for solar mainly depends on two things. First, there needs to be enough sunlight hitting the roof to generate the electricity you need. Second, check for any shade from trees or nearby things that might block the sun and affect how well the solar panels work. Most homes can support solar panels structurally, so the big things to look at are sunlight and shade in the areas where panels would go.
You don’t need to replace your roof before installing solar panels. Typically, roofs less than 15 to 20 years old are suitable. However, if your roof is over 25 years old, it may need a closer inspection to determine if it’s still in good condition for solar installation or if replacing it would be advisable. This assessment is crucial to ensure your roof supports and protects your solar investment effectively.
Solar panels don’t work during a power outage. Most solar systems are meant for self-use only, even those with batteries. Only systems specifically set up with batteries for backup power will work during an outage. If having backup power during outages matters to you, make sure your system is set up with this capability from the beginning and includes emergency reserves.
If you sell your home after installing solar, there are a few options. If you own the system, you can pay it off during the home sale through escrow. This can increase the home’s value since it includes a paid-off solar system. If the system is leased or rented, you typically transfer the lease to the new owner, who takes over the existing agreement.
Yes, you’ll still have an electricity bill, but it’s usually quite low, typically ranging from $10 to $30 per month, depending on the season. When your solar system is sized correctly, it can supply 95% to 99% of your home’s electricity needs, including what’s stored in the battery. There will still be a connection fee to stay connected to the grid, but overall, switching to solar significantly reduces your electricity costs.
With recent changes to the net metering policy, it’s now more financially beneficial to install a battery and store your excess solar power rather than sending it to the grid. Storing power in a battery is a better financial option, so we recommend pairing your solar system with a battery under the new net metering policy.
To determine if your roof is suited for solar, we consider sun exposure, shade, and roof type. Your roof needs enough sunlight to produce power, so we check for any obstructions or shade. Composite and tile roofs are ideal for solar installation, while wood shake roofs are typically not suitable.
Quoting Process
The quoting process involves a few steps. First, we gather your home’s energy usage data from the past year. If you don’t have a full year of data, we estimate based on your home’s size and appliances. Next, we design a custom solar system for you. We then review the design and financing options together to find the best fit for your needs. If everything looks good and fits your financial goals, we start the project.
We need 12 months of energy data if you’ve been in your home for at least a year. This helps us accurately estimate your energy use and design the right system. If you haven’t been in your home for a full year, we’ll estimate based on your home’s size and appliances. We also consider future needs, like an electric vehicle, to ensure your system is the right fit.
We can provide a quote over the phone, on a video call, or in person. We prefer video calls or in-person meetings because they allow us to explain the details more clearly. However, we prioritize convenience for you, so we can deliver the proposal in whichever way you prefer.
We typically determine your home’s usage by obtaining usage data from your utility company, showing how much energy your home has used over the past 12 months. This allows us to design a solar system that meets your yearly consumption. If you don’t have 12 months of data, we can estimate your usage based on your home’s size and appliances.
The size of your solar system depends on how much electricity your home uses, including appliances like AC units, electric stoves, dryers, electric water heaters, lights, Wi-Fi, garage appliances, and even electric vehicles. Typically, you size the system to produce between 100 and 110 percent of your total annual home consumption. This covers all your electrical needs and prepares for any future increases or upgrades in energy usage.
Your battery backup proposal should include a solar system that covers 100% of your home’s energy use, a battery, and a way to provide power during outages. The backup system will ensure essential appliances stay powered during an outage. It should also include a backup mode for the battery and a reserve of 25-30% to keep power available in case of an outage.
Installation
Most solar systems can be installed in less than 60 days. If an electrical upgrade or re-roofing is needed, it might take a bit longer due to the permitting process and coordinating with the utility for power disconnection and reconnection. However, the majority of our clients see their installation completed within 60 days from financing approval or deposit payment.
We create structural and electrical plans to submit to the city or county building department. They perform a plan check to ensure everything meets code requirements. Once approved, they issue a permit. After receiving the permit, we proceed with installation. Following installation, the city or county will inspect the system to ensure it was installed according to the plans and is up to code.
Financing
You can finance your solar system in a few ways:
1. **Purchase cash **: Buy it with cash upfront
2. **purchase Loan**: Get a loan for 20 to 25 years with a low monthly payment and no upfront cost.
3. **Power Purchase Agreement (PPA)**: Rent the system with no upfront cost and pay for the power it generates at a lower rate than your utility.
These options let you choose how to pay for solar based on what works best for your budget and needs.
Most finance companies usually look for a credit score between 640 and 650 for solar financing, whether it’s for a purchase loan or a Power Purchase Agreement (PPA). They also typically want applicants to have a debt-to-income ratio of less than 55%. These criteria help determine if you qualify for solar financing.
The most common incentive is the 30% federal tax credit for investing in solar. On average, homeowners can expect to receive between $8,000 and $12,000 in tax credits, depending on the size of the solar project. This credit applies to the total cost of the solar system, including any necessary electrical upgrades for your home.

Maintenance & Troubleshooting
Yes, solar systems do need maintenance, but it’s minimal because they mostly run on their own. The main task is cleaning, recommended two to three times a year, typically in March and June, and after summer if panels get dirty. Rain usually keeps panels clean in winter. If you notice a red LED light on the inverter indicating a production issue, contact us for a physical inspection to ensure everything is working correctly.
Maintaining solar panels is affordable. The main upkeep is cleaning, recommended two to three times a year. At Supreme Solar and Electric, we charge about four to five dollars per panel for cleaning, depending on factors like home size and number of arrays. This cleaning is typically all that’s needed for solar panel maintenance.
If your solar system has problems, you can contact our support line. We offer support seven days a week. During the week, we usually respond within one to two hours, and on weekends, within 24 to 48 hours. We will troubleshoot and fix the system.
