FAQ

SolarSails is an intelligent solar energy system designed for electric vehicles. It automatically deploys solar panels on your vehicle's roof, tracks the sun for maximum energy generation, and charges your EV directly. With 1840W of TOPCon solar cells, it generates an average of 10kWh per day, adding 80km+ of range.

When you park your EV, SolarSails automatically deploys solar panels from the roof-mounted container. Built-in light sensors track the sun's position and adjust panel angles for optimal energy capture. The generated DC power flows directly to your vehicle's battery with less than 5% conversion loss. When you're ready to drive, the panels automatically fold back into the aerodynamic container.

SolarSails is designed to supplement your EV's charging, not replace it entirely. With 10kWh daily generation, it can cover most daily commuting needs (80-120km of range). In high-sunlight regions, many users may find they rarely need public chargers for daily use.

Unlike portable panels that require manual setup and fixed positioning, SolarSails is permanently mounted, fully automated, and features intelligent sun tracking. It deploys and folds automatically, tracks the sun throughout the day, and integrates directly with your vehicle's electrical system. No manual setup, no storage hassle, maximum energy generation.

TOPCon (Tunnel Oxide Passivated Contact) is the latest generation of solar cell technology, offering 22-25% efficiency compared to 20-22% for older PERC cells. TOPCon performs better in low-light conditions, has a lower temperature coefficient (less performance loss in heat), and is more durable. This means more energy generation from the same surface area.

Fixed solar panels can lose 25-40% of potential energy because they can't adjust to the sun's changing position. SolarSails' intelligent tracking system continuously adjusts panel angles to face the strongest light source, capturing 95%+ of available solar energy throughout the day. This is the key to achieving 10kWh+ daily generation from a vehicle-mounted system.

SolarSails uses precision actuators and sensors to automatically deploy solar panels when your vehicle is parked. The system detects parking status, checks weather conditions, and unfolds panels to optimal positioning. When you start the vehicle, sensors detect motion and automatically fold the panels back into the protective container. The entire process takes less than 30 seconds.

SolarSails has built-in weather detection. In heavy rain, strong winds, or hail, the system automatically folds the panels into the protective container. The container is IP67 waterproof rated. Solar panels also generate some energy on cloudy days (typically 10-25% of sunny day output), and the tracking system optimizes for diffuse light conditions.

On a sunny day, SolarSails generates 10+ kWh, which translates to approximately 80-120km of additional driving range. Actual generation depends on location, season, and weather conditions. In regions with high solar irradiance (like western China, Australia, Middle East), daily generation can exceed 12kWh.

For most daily commuting (30-50km), SolarSails can cover your charging needs entirely. For longer trips, you'll still need public or home charging. However, SolarSails significantly reduces charging frequency and costs. Many users report reducing public charging needs by 60-80%.

Yes. Solar panels actually perform better in cold temperatures (lower temperature coefficient). While winter days are shorter and sun angles lower, SolarSails' tracking system compensates by optimizing panel angles. Typical winter generation is 40-60% of summer output. In snowy regions, the tracking system helps shed snow from panels.

SolarSails is designed for professional installation to ensure safety and optimal performance. The installation process takes approximately 15 minutes for trained technicians. The system uses vehicle-specific mounting brackets that don't require drilling or permanent modifications to your vehicle.

SolarSails is compatible with 95%+ of electric vehicles on the market, including sedans, SUVs, and crossovers from major manufacturers. The system uses adjustable mounting brackets that accommodate different roof shapes and sizes. Check our compatibility list or contact us for specific vehicle inquiries.

SolarSails comes with a 5-year comprehensive warranty covering all components including solar panels, actuators, tracking system, and electronics. Solar cells are warranted to maintain at least 80% of rated output for 25 years. Extended warranty options will be available.

We are planning to launch our Kickstarter campaign in 2026. Join our waitlist to be the first to know about the launch date, early-bird pricing, and exclusive perks. Waitlist members will get priority access and special discounts.

Final pricing will be announced at the Kickstarter launch. We're targeting a price point that makes solar charging cost-effective within 2-3 years of use compared to public charging costs. Early-bird Kickstarter backers will receive significant discounts.

We plan to ship worldwide, with initial priority to regions with high EV adoption and solar irradiance. Shipping details, costs, and timelines will be announced during the Kickstarter campaign. Join our waitlist for updates.

SolarSails is developed by a team of engineers and entrepreneurs passionate about renewable energy and electric vehicles. Our team has expertise in solar technology, automotive engineering, and product design. We're on a mission to make every EV a mobile power station.

Our mission is to let every EV charge itself. We believe electric vehicles have transformed transportation, and now it's time to transform how they get energy. By combining solar power, automatic deployment, and intelligent tracking, we're giving EVs more freedom and less dependence on charging infrastructure.
