Solar 101 – How Solar Works
Solar energy might seem complex, but we break it down so you can see how simple and beneficial it really is. When the sun is shining, electricity travels from the panels through wires into a piece of equipment called an “inverter.” The inverter transforms the DC electricity that the panels produce into the AC power that your home requires. After the inverter converts the electricity, it then travels through a dedicated wire into your home’s electrical panel. From that point on, all of the extra electricity your solar panels produce flows back through the power lines and into the utility company’s power grid.
The Basics Made Simple
Is My House A Good Candidate For Solar?
There are 3 main factors that determine whether your home is a good candidate for solar energy:
- Does it get a sufficient amount of direct sunlight (not overly obstructed by shade)?
- What is the orientation of the roof (technically “Azimuth,” which means North, South, East, and West)?
- Roof condition, shape, and size
Direct Sunlight
The sunlight has to make it to the solar panels in order for them to work. If the roof of your house gets a lot of direct sunlight during the day, then it may be an ideal candidate for solar. Having a shaded or obstructed roof, however, doesn’t necessarily mean that you can’t go solar, as there are several ways to overcome the challenges of shade.
- Power Optimizers or Micro-Inverters can improve a system’s performance, allowing each panel to work independently, ensuring that each panel produces as much electricity as it can when it receives sunlight. When one panel is shaded, its output goes down, but the rest of the system is unaffected. This is particularly effective to overcome the impact of tall trees in a nearby neighbor’s yard.

Orientation Of Your Roof
For solar energy systems to be the most efficient, it’s ideal for solar panels to face south. East and west-facing roofs may not get as much direct sunlight as those that face south, but quite often, it’s still plenty to produce all the electricity your home will need. A home with panels that face east or west can often get up to 80% of the efficiency that a house with south-facing panels would, so even if it’s not a “perfect” alignment, a few additional panels may be all that’s needed to achieve the results you want, and the savings would still be quite substantial.
Roof Condition, Shape, and Size
Once installed, a solar system can function efficiently for over 25 years, so you’ll want your roof to be in good shape before you have solar installed. If your roof is in poor condition or is getting old, it may be necessary to replace your roof before adding solar panels. If that is your situation, you may be in luck! If you include the roof replacement as part of the solar project, the savings can help offset the cost; it’s like getting a new roof with solar!
Roof shapes vary considerably with different house styles. The ideal roof shape for solar is a simple rectangle-shaped “gable” roof, wherein many panels as needed can be installed without any concerns about space. Solar can also work fine with other roof shapes, even those with many dormers or valleys; it’s just a little more challenging to configure or fit the proper number of solar panels on the roof to meet the energy needs of the home.
