Demystifying solar energy: What you really need to know

The rise of solar energy in Quebec and elsewhere has brought with it a wave of innovation, but also many persistent misconceptions. At Silent Energy, we believe that empowering our customers starts with accurate information. In this post, we clarify some of the most common myths about solar energy and offer practical advice based on real-world experience.

Myth 1: “You can plug a solar panel directly into a battery.”

Not really, except in rare cases.While it’s technically possible to connect a small solar panel directly to specific battery types (e.g., for fence chargers), this setup is not recommended for most applications. In standard installations, a charge controller is essential to stabilize voltage and protect the battery.

At Silent Energy, all our units include an intelligent MPPT charge controller that ensures optimal performance — even in extreme cold.

Myth 2: “Batteries are always more expensive than adding more panels.”

True — but context matters.High-quality lithium batteries like those from our partner Volthium cost more per unit than a solar panel. However, system economics depend on several factors: target autonomy, seasonal or year-round use, available space, etc.

Often, it’s more cost-effective to maximize solar input than to oversize your battery bank. That’s why our experts help you right-size your system to match your real needs — not just your assumptions.

Myth 3: “More batteries = better system.”

Not necessarily.A large battery bank is useless without enough solar input to charge it. Overinvesting in batteries without balancing production capacity reduces efficiency.

That’s why all our systems are scalable — with the ability to add more panels as your energy needs grow or change with the seasons.

Myth 4: “Solar doesn’t work in winter.”

Absolutely false.Thanks to Québec innovation, our generators are built with self-heating lithium batteries and cold-weather-rated electronics that operate reliably down to -40°C.

Silent Energy systems are 100% four-season ready — built for remote lodges, northern job sites, and off-grid industry operations across Canada.

Conclusion

Too many people — individuals and businesses alike — end up redoing their solar installations two or three times after following poor advice.

At Silent Energy, we’re committed to education, transparency, and personalized support. Our mission is to deliver reliable, clean, silent, and winter-ready energy autonomy, without compromise.
