ACOPOWER 20 Watt Mono Solar Panel for 12 V Battery Charging, Off Grid: Frequently Asked Questions

How long is the warranty on this panel?
ACOPOWER's general warranty policy covers its solar panels for 5 years from the original purchase date, with proof of purchase. ACOPOWER's product materials quote longer workmanship and power-output terms in places, and they don't all agree, so rather than guess we'll confirm the exact terms for your order in writing. Call (303) 876-7654 before you buy if the long-term output guarantee matters for your project.
Can this charge a 12V battery by itself?
It can keep one topped up. At 1.14A at maximum power, a 20W panel suits maintenance charging and small loads, not quickly recharging a large battery bank. Pair it with a solar charge controller. Call (303) 876-7654 and we'll help you match it to your battery.
Can I add more panels later?
Yes. Panels can be wired in parallel to add current, as long as the total stays within your charge controller's rating. Call (303) 876-7654 if you are planning a bigger array.
Can I install this myself, or do I need an electrician?
Small 12V systems are a common DIY project, but any wiring to a battery bank, inverter, or your home's electrical system should follow the manufacturer's manual and local electrical code. If you're unsure, a licensed electrician or solar installer is the safe choice — call (303) 876-7654 and we can help you figure out what your setup needs.
Do you offer financing or price matching?
Yes. We offer 0% APR financing options through Affirm at checkout, and our Lowest Price Guarantee applies — if you find this product cheaper at another authorized ACOPOWER dealer, call us at (303) 876-7654 before you order and we'll take care of it.
