People often assume that switching to renewable energy requires a massive financial commitment and a complete roof overhaul. But tapping into the sun can actually start much smaller, powering everything from a remote security camera to a vehicle battery without any major construction.
Sorting through the specifications for the Best Solar Panels 2020 does not have to feel like studying for a physics final. Let us walk through the top options available right now so you can find the exact match for your power needs.
Key Takeaways
- Match your panel's wattage output directly to the energy demands of your specific device, whether it is a small video doorbell or a heavy-duty battery maintainer.
- Verify the connector type and port compatibility before purchasing to ensure the panel plugs directly into your device without requiring extra adapters.
- Look for weatherproof construction with sturdy outer frames if the panel will stay outdoors permanently exposed to rain and extreme temperatures.
- Consider bifacial technology if you want to capture sunlight from both sides and squeeze extra efficiency out of reflected ground light.
- Check the physical dimensions and mounting hardware included in the box to make sure you have adequate space and a secure spot for installation.
