A lithium battery is not a mandatory requirement, without which foldable solar panels won't work. Folding panels will still work without the batteries as long as sunlight is available. However, after sunset, these panels will not be able to power your devices.
Foldable solar panels are used for on-the-go charging, and they provide emergency power backup to charge appliances in remote and off-grid locations. On the other hand, rigid rooftop solar panels can power an entire household.
Fixed solar panels are most recommended and widely used when installing rooftop solar panel systems for homes and housing societies because they're a lot more rugged than retractable solar panels. They last for 25+ years, unlike folding solar panels that have a lifespan of just 5-10 years.
If you're looking for a long-term solution to power your home, traditional fixed panels are more efficient and cost-effective in the long run. Foldable panels are best suited for individuals who need a portable energy source, while traditional panels are better for those who want a permanent, higher-output system.

A 15kW Solar Kit requires up to 1,200 square feet of space. 15kW or 15 kilowatts is 15,000 watts of DC direct current power. This could produce an estimated 1,000 to 2,500 kilowatt hours (kWh) of alternating current (AC) power per month, assuming at least 5 sun hours per day with the solar array facing South.
