Some other sources of variation: 1. The difference between summer and winter. In Oregon where I live, the winter produces around 15% of the summer. Which means that when you live off-grid you need 400-700% more solar panels than based on the average calculation. 2. Temperature: Solar panels produce a lot less at high temperatures than at low temperatures. A 400W solar panel produces that only at room temperature and full sun. In Florida you have to subtract at least10-15% of the maximum power
Nice video. In calculating projected solar panel wattage, A big factor to consider is that a solar panel will not produce the Standard Test Condition (STC) rated wattage. This is because of panel efficiency issues and heat. You will also need to consider sun hours, shading/placement. To start, it would be better to calculate projected wattage using the Nominal Module Operating Temperature (NMOT or NOCT) rating to get a more accurate number to achieve your desired energy goal. Thanks.
Average house uses 886 KW hours each month so divide that by 30 and it’s 29.5 KW hour daily requirement . 2 Kw hours isn’t anywhere what we need . That’s from the department of energy the stats of an average house uses.
Dude, great content! Super-helpful 101. Some constructive criticism? Slow down. You're talking fast, which is making it harder to follow, and you're also running out of breath, which means your volume is dropping at the end of many of your lines. Totally okay to stop mid-sentence, take a breath, and go on if needed. What's most important is that we can hear your great content so we want to come back for more! What do you think of battery backup systems? Should I install my inverter and batteries outside in a shed or in my basement? Are there affordable solar options that also allow for wind energy options in tandem once those start becoming more affordable? I want to see more!

Very interesting. I'm in the sthn hemisphere so face nth is better. I'm also interested in the temperature range for panels. It gets to 48°c here

Good info. Real world examples help a lot.
Prior to getting solar in California; heat waves and drought.
After getting solar ; cloudy and raining for 4 months.

My fridge alone uses 2 kWh/day!
