	The OBI + OSE Off-Grid PV Workshop is a workshop where you will learn to design, install, and live with a complete, rooftop, 3kW, off-grid PV system for a home - for $3000 in materials. We have tested this system in the Seed Eco-Home - and decided to build more of these. The workshop involves a complete build + install of a 3kW system from the roof mounting system - to a control panel with power measurement, a battery bank, wall outlets, and a super-efficient refrigerator. We will show you how to convert a chest freezer to a super-efficient refrigerator which draws only 8 watts of power on average. This 12x less than an average refrigerator - and is one of the critical elements that allow for building a low cost system with a small battery bank - as the main load at night is a refrigerator. We will measure all the loads in the system - so that a power management strategy emerges for running all loads in summer and winter. This is based on our experience with the system, and we recommend it for replication. The intended audience is anyone who wants to learn about PV systems first hand - and especially anyone who wants to pay their last utility bill by investing $3k for a complete off-grid system like ours.
