Great question! Here’s a quick, step-by-step guide you can follow:
Look for your monthly usage in kilowatt-hours (kWh). The average U.S. home uses about 900 kWh per month, or about 30 kWh per day.
Consider how much sunlight your area gets every day–this is called “peak sun hours.” For example, if you live in sunny South Carolina or Georgia, your home probably averages around 5 peak sun hours per day.
Daily energy usage (kWh) ÷ peak sun hours = system size (kW)
Example:
System size (in watts) ÷ panel wattage = number of panels
Examples:
Still unsure? Don’t worry–Solar Energy Partners is here to help. We’ll review your electricity usage and handle all the calculations for you, designing a system that fits your energy needs, roof space, and budget. We also factor in shade, battery storage, and local weather, ensuring you get the most out of your solar investment.
Roof size is one of the most important factors to consider when designing a solar system for your home or business. Here’s why:
It’s important to remember that these aren’t one-size-fits-all rules—every roof is different. That’s why partnering with an experienced installer like Solar Energy Partners is the best way to ensure your system is perfectly designed to meet your energy needs, space, and budget.
Most solar systems are designed to last 25 to 30 years, and many continue producing power well beyond that. While panel efficiency gradually decreases over time, high-quality systems remain effective for decades.
What really matters is the durability and performance of the components. Smaller parts of your system, such as inverters, optimizers, and monitoring hardware, typically have shorter lifespans, about 10 to 15 years.
By partnering with reliable suppliers and experienced solar companies like Solar Energy Partners, you’ll benefit from strong warranties and ongoing maintenance to protect your investment and keep your system performing at its best.
Savings with solar can start right away and grow over time, but the exact amount depends on a few key factors:

Yes, you can! With our solar batteries, you can store any extra energy your system produces during the day.
This stored energy can be used:
Getting started with solar is simple. Here’s how our process works:
Solar energy produces electricity without burning fossil fuels, which helps lower greenhouse gas emissions and reduces harmful air pollutants. It also doesn’t require water to operate, unlike many traditional power sources, making it a more sustainable and environmentally friendly option for long-term energy use.
Shade can reduce a solar system’s performance, but only slightly in most cases. Your system will still generate energy, though the output may decrease depending on how much sunlight is blocked and for how long.
During your consultation, Solar Energy Partners will assess any shading on your property and recommend the best solutions, such as alternative system placements, high-efficiency panels, or microinverters.
Yes, your solar battery will still work on cloudy days. While it charges most efficiently in full sun, it stores extra energy from brighter days and can discharge that power when needed.
Most modern systems include mobile apps that let you customize how your battery is used. You can decide how much energy to use daily and how much to reserve for emergencies or outages.
We recommend installing your solar battery indoors, typically in a garage, where it's protected from temperature extremes and weather exposure.
Outdoor installations are possible but should be in shaded, well-ventilated areas where temperatures stay between 15–110°F and the unit is shielded from rain, snow, and direct sunlight.
A community solar program lets you enjoy the benefits of solar energy without installing panels on your home or business. Instead, you subscribe to a share of a local solar farm, and the electricity it produces is credited directly to your utility bill, lowering your energy costs.
Thanks to support from the New York State Energy Research and Development Authority (NYSERDA), community solar is widely accessible. You can join if you:
In New York, you don’t need to live next door to a solar farm to join a community solar program. As long as you’re in the same utility service territory as the project, you’re eligible to subscribe.
The flexible model allows renters, apartment residents, and others without rooftop access to benefit from clean energy while also helping expand solar access across the state.
Yes–community solar slots can fill up quickly.
These programs are in high demand because they offer real financial benefits, flexible contracts, and a smooth sign-up process, especially when backed by trusted providers like Solar Energy Partners.
This combination of value and reliability makes them incredibly appealing, so it’s smart to act early if you’re interested.
Residential members can unsubscribe from their community solar program at any time with just 30 days’ notice. While businesses may opt for longer-term commitments with additional terms, our goal is to keep clean energy flexible and accessible, without locking you into a long contract.
Absolutely! Subscribers can save up to 15% on their monthly electricity bills. Plus, membership comes with added perks like gift cards and exclusive SEP community offers that unlock discounts at popular retail, service, and hospitality locations.

A solar energy system uses photovoltaic (PV) panels to capture sunlight and turn it into electricity. These panels are mounted on your roof and connected by wiring to an inverter, which converts the energy from direct current (DC) into alternating current (AC), the type of power your home uses.
From there, the AC electricity flows to your home’s main electrical panel, powering your lights, appliances, and more. It’s clean, efficient, and happens silently from sunrise to sunset.
In most cases, installing solar panels will not increase property taxes.
While a solar system can boost your home’s value by making it more energy-efficient and attractive to buyers, many states (including South Carolina and Georgia) offer property tax exemptions for renewable energy upgrades.
Of course, local laws can vary, so our team will help you understand what applies in your area during your solar consultation.
The average cost of a home solar installation is around $25,000, though this can vary depending on your energy needs, system size, and equipment choices.
The good news is you don’t have to pay it all upfront. Many homeowners take advantage of flexible financing options, solar loans, or cash payments, as well as federal and state tax credits that help you save thousands.

Yes, but not very often. Rain and snow usually do a good job of keeping solar panels clean. However, over time, dust, pollen, or debris may build up and slightly reduce performance.
If you notice a drop in energy output, a gentle cleaning with soft brushes or sponges and non-abrasive, eco-friendly soap can help.
Not comfortable doing it yourself? Contact a professional, like Solar Energy Partners, to handle the maintenance.
There’s no one-size-fits-all answer—every commercial property is unique, and the best solar system depends on your specific energy needs, layout, and goals. Key factors to consider include:
It’s important to always partner with a solar supplier and installation company you can trust. Be sure to look for strong warranty coverage, proven installation experience, and ongoing support to ensure your system performs reliably and delivers the best return on investment.
With proper maintenance and quality installation, commercial solar panels remain highly efficient for decades. Most panels lose only about 0.5% to 1% of their output per year, meaning even after 25 years, they can still operate at 75–90% of their original efficiency.
Commercial solar panels typically last 25 to 30 years before needing replacement, but many continue to produce energy beyond this timeline (although with slightly reduced efficiency).
Panels generally don’t need to be fully replaced unless there’s a significant drop in performance or they’ve been physically damaged. Other components, like inverters or batteries, may require attention or replacement before the panels themselves.
Yes, keeping commercial solar panels clean helps maintain their efficiency. While rain and snow naturally wash away some dirt, larger commercial arrays tend to accumulate more grime, dust, and debris over time due to their scale and exposure.
To ensure optimal performance, we recommend professional cleaning at least once a year. Regular maintenance can help maximize energy output and extend the life of your system.
