Can you be completely off-grid with solar panels?
For grid-tied solar panels, grid failure means solar failure, so without more, solar panels can’t take you off grid. Even if they could work while the grid were down, you would still have a big problem: since solar panels only generate electricity during the day, you would be left in the dark all night.
How much does a DIY off-grid solar system cost?

What size generator do I need for off-grid solar system?
take your corrected watt – hrs per day, divided by 3 sun hrs/day = the array size this is a good 3 season average number to divide by Eg. 5000 watts /3 = 1660 watts This is the minimum size solar array needed. If there will be shading, adjust accordingly.
How much does 10kW off-grid solar system cost?
between $10,000 and $15,000
A 10kW solar PV system will typically cost between $10,000 and $15,000, while a 30kWh battery would cost around $25,000 based on current pricing. Assuming the power requirements are only single phase then the total cost for a 10kW solar and 30kWh off grid solution would like come to around $50,000.
