Buying guide
3 parts, about 3 min readBefore you buy
First-time buyers often underestimate the importance of solar panel placement and local sun exposure when selecting solar-powered products. A solar attic fan or street light that works well in Arizona may underperform in Seattle due to shorter daylight hours and cloud cover. Check the product's battery capacity and solar panel wattage against your region's average daily sun hours to avoid disappointment. Langy Energy's product descriptions should list these specs, but if they don't, contact their support before ordering.
For bug zappers, placement matters more than wattage. Position the zapper 15 to 25 feet away from your main gathering area so insects are drawn away from people rather than toward them. Mount it at a height between 4 and 6 feet, and avoid placing it near competing light sources that dilute its effectiveness. Solar street lights need unobstructed southern exposure (in the Northern Hemisphere) for the panel to charge fully, so scout your installation spot before committing to a pole height or mounting style.
What to buy
Langy Energy's solar attic fans and attic gable fans are designed to ventilate hot attic spaces using sunlight, reducing the load on your air conditioning system. These fans mount on the roof or gable end and run automatically when the sun hits the solar panel. They're a good starting point if you've never installed ventilation equipment, since most models require only basic cutting and mounting without electrical wiring.

The bug zappers and mosquito zappers use UV light to attract insects, then eliminate them with an electric grid. Langy Energy offers both solar and plug-in versions, with the solar models suited for yards and patios where running an extension cord isn't practical. The bug light models serve as combination area lights and insect control, useful for porches and outdoor dining areas.
Solar street lights from Langy Energy are standalone pole-mounted fixtures with integrated solar panels and batteries. The 200 watt street light models provide higher lumen output for driveways, parking areas, or large yards. These lights turn on automatically at dusk and are popular with first-time buyers because they eliminate trenching for electrical lines. The UFO high bay light is a ceiling-mounted LED fixture for garages, workshops, or covered patios, named for its round, shallow profile. It's a standard plug-in model rather than solar-powered, designed for spaces that need bright overhead lighting.
How to save
The NANCY code gives you 5% off across the entire Langy Energy catalog, so you don't need to wait for category-specific promotions. Since the code works on all orders, it's worth using even on smaller purchases like a single bug zapper or attic fan. First-time solar buyers can apply the discount immediately rather than gambling on future sales that may not materialize.

Combining multiple items in one order maximizes the value of your 5% savings, especially if you're outfitting a property with several lights or fans. Langy Energy ships physical products, so consolidating your purchase also reduces shipping costs compared to placing multiple small orders. If you're exploring other home improvement projects, check out related savings like the Doorbell Mount coupon code for complementary upgrades.
Watch for seasonal clearance on previous-generation models if Langy Energy updates their product line, though the Langy Energy promo code applies to current inventory. Since solar products perform differently depending on your local climate and sun exposure, read product specifications carefully to ensure the wattage and battery capacity suit your region's sunlight hours before buying.
