Solar Panel Types & New Technologies
Not all solar panels are the same. Efficiency, cost, and lifespan can vary…
- Monocrystalline vs. polycrystalline basics.
- Bifacial panels and how they capture light from both sides.
- Emerging perovskite technologies and what to watch for.
Recommended Starter Panels
If you are experimenting with a small starter setup or want to learn the basics of solar wiring, a 100 W monocrystalline panel is a practical place to begin. A simple 100 W panel such as this starter panel can be matched with a small charge controller and battery to build a first test system.
For those planning growth or higher-output systems, a 200 W bifacial panel like this 200 W bifacial model offers significantly more capacity.
To connect your panels to the rest of the system, you’ll typically need MC4 extension cables. A reliable option is this 20 ft 10 AWG MC4 cable pair from Renogy, which provides low-resistance wiring suitable for most small solar setups: view the cable set here.
Most solar installs also require a set of standard MC4 connectors for joining panels, extending wiring, or making secure connections to charge controllers. A dependable option is this double-sealed male and female MC4 connector pair from Renogy: view the connector kit here.
For growing systems, a dependable MPPT charge controller is essential. The Renogy Rover 30A MPPT is a popular and reliable choice for 12V or 24V setups, offering excellent efficiency and room for future expansion. You can view the controller here: Renogy 30A Rover MPPT.
Solar Panel Types & New Technologies
Not all solar panels are the same. Efficiency, cost, and lifespan can vary significantly between different types of panels, and new technologies like bifacial modules and perovskite cells are opening the door to even more possibilities. This page gives a simple overview, with a focus on what works in cold-climate communities like ours.
Common Solar Panel Types
Monocrystalline panels are made from a single, continuous crystal structure. They tend to be more efficient, perform better in limited space, and usually cost a bit more upfront. For small rooftops or tight sites, mono is often the best choice.
Polycrystalline panels are made from multiple crystal fragments melted together. They are usually slightly less efficient, but can be more affordable. For installations where you have plenty of roof or ground space, poly can still make sense.
Thin-film panels are lightweight and flexible, but usually lower in efficiency. They can be useful in specific situations (like RV roofs or certain industrial applications), but are less common for typical home systems in cold climates.
Bifacial Panels
Bifacial panels are designed to capture light on both the front and the back of the panel. The front side behaves like a typical panel, while the back side picks up reflected light from bright surfaces such as snow, light-coloured gravel, or reflective roofing.
In snowy climates, bifacial panels can be especially helpful. Snow on the ground can act like a natural reflector, increasing the total energy output compared to a similar-sized monofacial panel. Mounting height, tilt, and the surface beneath the panels all influence how much extra energy you get from the second side.
For people planning to grow their system over time, or looking to get more energy from a limited space, a bifacial panel can be a strong option when paired with good mounting and site design.
Emerging Perovskite Technologies
Perovskite solar cells are an emerging technology that has shown very high laboratory efficiencies and the potential for low-cost production. Researchers are exploring ways to combine perovskites with traditional silicon cells to create “tandem” panels that capture more of the solar spectrum.
Today, most perovskite products are still in the research, pilot, or early commercialization phase. For typical homeowners, it usually makes more sense to focus on proven monocrystalline and bifacial modules, while keeping an eye on how perovskite technology develops over the next decade.
Performance in Cold-Climate Communities
Solar panels actually like the cold. Their efficiency drops with high heat, so cold, clear winter days can produce excellent power when the sun angle and snow cover are favourable. The main challenges in our climate are snow buildup, shorter winter days, and low sun angles.
Key considerations for cold-climate installations include:
- Tilt angle: Steeper angles can help shed snow and improve winter production.
- Mounting height: Slightly higher mounting can reduce snowdrift buildup, especially for ground mounts.
- Access for maintenance: Being able to safely brush or clear panels (if needed) matters in heavy snow years.
- Durability: Look for panels rated for snow load and wind load appropriate to your region.
Recommended Starter Panels

A simple 100 W panel such as this starter panel can be matched with a small charge controller and battery to build a first test system. (Replace this link with your chosen 100 W panel.)
For people planning growth or looking for more output from the beginning, a 200 W bifacial panel like this 200 W bifacial model offers significantly more capacity in a similar footprint. In the right conditions, the rear side of the panel can boost production by capturing reflected light from snow or light-coloured surfaces.
To connect your panels to the rest of the system, you will also need basic wiring and connectors. Extension cables and MC4 connectors such as this type of MC4 cable set can help when your panels need to sit farther from your charge controller or battery bank.

Next Steps
Choosing the right panel is only one part of designing a good renewable energy system. Matching panels with an appropriate charge controller, battery bank, inverter, and safety equipment is just as important. As this section grows, you’ll find links to guides on charge controllers, batteries, wiring, and system sizing to help you plan a safe, efficient setup for your home or project.
