Not OP. The van in the article appears to have ~800W of solar on the roof. Depending on preference, lighting requirements can be ~5-30W, laptop requirements ~20-150W. If heating and cooking needs are met with natural gas (the most common solution- and I can see a gas pizza oven in the article). Making some assumptions: * the solar panels deliver average ~200W for 8hrs per day, 1.6kWh total * OP has average 50W power draw while working, 8hrs per day, 0.4kWh total * OP has lighting requirements of ~20W, 4hrs per day, ~0.1kWh I guess he's probably fairly comfortably net positive for electrical power. In my experience the solar panel estimate is reasonably conservative, although I've experienced some extended periods of very bad weather where my panels produce less than 5% of their rated maximum (in the UK- not Aus!). |
