The cost of solar power systems varies based on your power needs. A basic battery topper system, including a large panel and a solar controller linked to your house batteries, can be installed for under $1,000.00$. Systems for RV's and Vans that powers all your 12-volt appliances, such as a TV, surveillance system, laptops, and small power tools, with a lithium battery, multiple large panels, a controller, and an inverter, can range from $2,400.00 to $3,600.00$, depending on the chosen lithium battery capacity. For a full 48-volt home system for your toy hauler, featuring a 15 kw to 30 kw lipo battery and a 5000 watt inverter to run your AC and microwave, prices begin at around $11,000.00$ and go up based on the battery size and number of solar panels. We also provide large 72-volt systems for homes and off-grid locations starting at $14,000.00$, which include six large panels and a 22kw lipo battery with 12 kw inverters, up to comprehensive off-grid setups with a 30 kw lipo battery, 15kw inverters, and a full pallet of solar panels for under $20,000.00$, fully installed.
