This is a guide for building a self-installed, off-grid solar backup system for under $1,000, designed specifically for renters.

From the sources
Backup (and savings) with self-install solar & batteries. Works with condos, rooftops, balconies or yards. 1.2kW solar panels removably placed on the apartment's roof & "sunbox" downstairs: 3kW controller/inverter/UPS & 2.5kWh battery powering the apartment Stored sunlight runs the kitchen, dining & living room, organized into strings of devices - carefully picked devices plugged into a right-sized extension cord. Each string is designed to never draw more than 1000W so as to not warm the extension cables, and in aggregate not max out the inverter. It doesn't run my lights - it's a pain to get an alternate power system to everywhere lights are required. But LEDs nowadays are in the 2-5 watt…from sunboxlabs.com
