How long do solar string lights stay on at night?

On a full charge, you can expect 6 to 8 hours of light. A full day of direct sunlight gives the best results, but the USB port lets you top off the battery if your spot doesn't get enough sun.

Can you leave solar string lights out in the rain?

Yes. These have an IP65 waterproof rating, which means they're protected against water jets from any direction. Rain, snow, and humidity won't damage them. Just make sure the USB port cover is closed when you're not charging.

Do solar string lights work in winter?

They do, but shorter days and weaker sunlight mean less charge time. You'll get fewer hours of light per night during winter months. The USB charging option helps fill the gap when solar alone isn't enough. --- *As an Amazon Associate, PeekBuys earns from qualifying purchases. Prices and availability are subject to change.*

If you're looking for outdoor string lights that don't need an outlet, solar-powered options have become the obvious choice. These 33 ft waterproof string lights solve the two biggest pain points with outdoor lighting: running extension cords and replacing broken bulbs. With both solar and USB charging, they actually work on cloudy days too.

Key Features

Covers 33 feet total (27 ft light strand + 6 ft lead wire) with 9+1 shatterproof LED bulbs that won't break if they fall or get knocked around.
Dual power sources with a solar panel and USB port, so you can charge them even during stretches of bad weather.
Includes a remote control with 3 lighting modes, letting you switch between steady, flashing, and fade without climbing a ladder.
IP65 waterproof rating means they handle rain, snow, and sprinkler overspray without shorting out.

Who Should Buy This?

These are built for anyone who wants to light up a patio, backyard, or campsite without dealing with electrical outlets or fragile glass bulbs. They're a solid fit if you rent and can't install hardwired fixtures, or if you want portable lights you can take camping. The remote control makes them especially practical if you've strung them up high or across a pergola where reaching the switch isn't easy.

Buying Tip

Pay attention to the total vs. lighted length when comparing solar string lights. This set is 33 ft total, but only 27 ft of that is the lighted section. The other 6 ft is lead wire from the solar panel to the first bulb. Make sure the lighted length actually covers your space.
