I’ve already did this on a much larger scale for my entire house. The LED lights are charged from a solar panel from a VW, the panel was $15 on ebay. Then the batteries I get free of charge. One can go to any garage and tell the mechanic that you will take the batteries off of their hands and they can keep the $9 per battery EPA fee that the customer is charged. So you get a free car or marine battery, the keep the money, its a win-win situation!!! The panel charges the bank of batteries all day. I use isolation diodes first to prevent a discharged battery from being charged by a fully charged battery. Second, when the battery is equal to the solar panel voltage the diode reverse biases and charging stops. My house has LED lighting above every window and door on the outside of the house. On the inside of my house each room has one or more LED domes that I make myself. The entire setup only consumes maybe 5 to 10 watts at the most. Additionally, with the system being 12 volts DC and very low current, it is not a fire hazard. The car and marine batteries are outdoors, away from my house, and shaded. I invented my system before Katrina hit us. I have FREE lighting from this. It saves on the electric bill, and the LED’s barely cause any heat at all. Every house needs to have the system that I designed!!! The total cost I have in the entire setup is not even $50. I get the lights from Walmart. They cost $3.50 for a pack of 4. I then solder in a 220 ohm current limiting resistor, and run the wires through the top. I have the wiring in my attic, I bought a single roll of 4 pair/100 foot roll of telephone wire, it was about $20. It gives me 4 lines that are 100 foot each. I have the same roll for over a decade and have not run out!. I poke a hole in the ceiling with an ice pick, poke the wire into the attic through the hole, then hot glue the dome to the ceiling. All of the wiring runs to a back bedroom where I have a control panel. The bedrooms have only a single LED so it will be night lighting. Then key places like the kitchen and bathroom have domes consisting of many LEDS. Rooms like the laundry, dining, and living rooms are lit a bit dimmer. When AC power goes out a relay turns off, and connects from my power supply automatically to battery backup! If anyone is interested, I wrote a very great article that I can send you. Just give me a thumbs up here, or a like on Facebook, and I will email you the article!!!
