3. How is RV solar different from home solar?
It’s crucial to differentiate between travel or camping solar panels for vans/RVs/motorhomes and home solar panels. Home solar panels are larger and installed on roofs to meet a home's energy needs. In comparison, RV solar panels are smaller and are designed to maintain battery power and charge the appliances used in the RV for daily life needs.

5. What are solar panels and how do solar panels work？
Solar panels use sunlight to generate electricity. Panel's current flows to the charge controller, which manages battery charging and prevents overcharging, keeping the battery safe. Batteries store direct current. Inverters convert direct current into alternating current for use in everyday appliances. In a home, the solar panels are connected to a grid inverter. RVs/vans/motorhomes use different inverters. Off-grid systems mainly include: solar panels (collection), charge controller (monitoring), battery (storage), inverter (use).

8. What are the different types of solar panels on the market?
When shopping for solar panels, please consider: monocrystalline vs. polycrystalline panels, flexible vs. rigid panels, portable vs. roof-mounted panels. Polycrystalline panels are cheaper but less efficient. In limited roof space on an RV or campervan, monocrystalline panels are more recommended. Rigid panels have the advantages of being waterproof and corrosion-resistant and require mounting brackets. They are best for small houses. Flexible panels are lightweight and adaptable, capable of bending. They are great for curved surfaces and non-traditional RV shapes. Portable panels are suitable for smaller energy needs and camping. They are lightweight and easy to handle. Residential rooftops require large-format solar panels, which are ideally suited to meet ongoing and larger energy needs, providing charging capabilities at any time. When designing a solar system, choose 12V, 24V or 48V. 12V is commonly found in RVs, vans and small cabins. 24V is suitable for larger residential and commercial buildings. 48V is used in large off-grid houses.
