Frequently Asked Questions


Q1: What battery can this 40W solar panel charge?

A: It works perfectly for charging 12V lead‑acid, lithium and deep‑cycle batteries, matched with a suitable solar charge controller.

Q2. Can I install the solar panel outside in all‑weather conditions?

A: Yes. The aluminum frame, tempered glass and IP67 junction box are engineered for long‑term outdoor use against rain, snow and UV rays.

Q3. How many amps does the 40‑watt solar panel produce?

A: Its optimum operating current reaches 2.42A under standard test conditions (STC:1000W/㎡,25℃).

Q4. Am I allowed to connect multiple 40W panels together?

A. Absolutely. Wire panels in series for higher voltage or parallel for bigger charging current for your power system.

Q5. Does the package include a solar charge controller?

A. This listing is only for the 40W monocrystalline solar panel. You can buy our matching 12V solar controller separately.
