Key takeaways


nterested in shrinking both your energy bills and your environmental impact? You're in luck—turns out your solution could be as close as your own rooftop or backyard. Solar energy isn't just a buzzword; it's a real, attainable option for powering your lifestyle in a more sustainable and cost-effective way.

What Exactly is a Solar System?

When we talk about a "solar system" for homeowners, we aren't talking about astronomy or exploring the Milky Way. We're actually talking about a straightforward setup that lets you grab solar rays and turn them into usable electricity for your home. In simpler terms, it's a way to turn sunshine into energy that can run your appliances, heat your water, and light up your life—often with the added bonus of lowering your monthly bills.

While it may seem like a complicated endeavor, it's actually a lot simpler than you'd expect. You don't have to be an engineer or a renewable energy guru; all you need is a willingness to embrace clean energy and a little know-how to get started.

Breaking Down the Components

Photovoltaic Panels

When it comes to solar systems, the most eye-catching feature is usually the solar panels themselves. These panels are made up of photovoltaic cells that transform sunlight into a type of electricity known as direct current (DC). The quantity of panels you'll need depends on two main factors: how much energy you typically consume and the level of sun exposure your location receives.


The DC electricity generated by the solar panels isn't immediately usable in your home; most household appliances need alternating current (AC) electricity. Meet the inverter: this important device converts the DC power from your panels into the AC power your home can actually use.

Battery Storage

While having a battery storage system isn't strictly necessary, it's definitely a plus. During sunny days, your panels might produce more energy than you can use. Instead of wasting it, you can keep it in batteries to use when the sun's not shining—like at night or during a blackout.

Charge Controller

Directing too much electricity to the battery can potentially overload it and reduce its lifespan. A charge controller manages the flow of electricity into the battery, making sure it's neither too much nor too little.

Energy Meter

Most solar systems are connected to the grid, which means you'll need a specialized two-way meter. This device keeps track of the electricity your system produces and how much of it goes back to the grid.

Racks and Mounts

This hardware keeps your solar panels in place, often using rails and clamps. Mounting systems should be made from durable, weather-resistant materials to ensure the longevity of your solar setup.

Monitoring Tools

Finally, most contemporary solar setups include monitoring tools that you can easily access through a smartphone app or computer. This system keeps tabs on your solar panel's performance, offering valuable information about your energy production and usage.

Off-Grid: For the Independents

If you're someone who values independence and wants to completely cut ties with utility companies, an off-grid solar system is your go-to option. In this setup, you're not hooked up to any electricity grid. Your solar panels, along with a set of batteries, are your personal mini-power plant, storing extra energy for those cloudy days.

The Upsides:

  • Complete energy freedom.
  • No monthly electricity bills.

The Downsides:

  • Setup costs can be high because of the need for high-power batteries.
  • If your batteries are drained and there's no sun, you're out of power.

On-Grid: Plug-In, Save, and Repeat

With grid-tied or on-grid systems, you're still connected to the power grid. These systems generate electricity when the sun is shining, which can be fed back into the grid when you're not using it. Later, you can receive a credit from your utility company for the electricity you provide to the grid.

The Upsides:

  • Lower upfront costs than going off-grid.
  • The grid is your backup power source.

The Downsides:

  • You'll still get electricity bills, albeit lower.
  • No electricity during power outages.

Hybrid Systems: A Smooth Blend

Hybrid systems are like the Swiss Army knife of solar setups. They connect to the grid but also come with battery storage. This way, you can store excess power for personal use and also have the security of grid power when needed.

The Upsides:

  • Flexibility in how you use and store energy.
  • You're covered during power outages

The Downsides:

  • Higher initial cost of the system due to the need for batteries.
  • The system is more complicated to install.

Installation Choices: Where to Put Your Panels

Rooftop Solar: A Room with a View

This system type is the most popular choice for homeowners. Rooftop installations are a great way to utilize unused space and get maximum sun exposure. If you're fortunate enough to have a flat or a south-facing roof, you're already ahead of the game. However, keep in mind that if your roof is deteriorating or heavily shaded, rooftop solar may not be your best bet.

Ground Solar: Stable and Steady

If your rooftop isn't an ideal fit or if you have a spacious yard, opt for ground-mounted panels. They're relatively easy to maintain and can be tilted for maximum solar exposure. One thing to remember is that ground systems do consume yard space. Before you commit, make sure to double-check zoning laws in your area.

BIPV: The Integrated Innovator

Last but not least, there's Building Integrated Photovoltaics, or BIPV. This cutting-edge system integrates solar panels right into your home's construction, such as windows or roof shingles. This offers a sleek and aesthetically pleasing solution. Be prepared, though: this system tends to be on the pricier side.
