A 30w solar panel will produce on average 25 watts of power per peak sun hour 12v 30w solar will produce 150Wh of DC power per day, considering 6 hours of peak sunlight and 12. 5 DC amps @ 12 volts The above percentage is based on the 30 days of power output from my 200 watt.
Solar panels can cost between $10,000 to $30,000 for small to medium-sized farms. Federal incentives, like the USDA's REAP, can cover up to 25% of solar project costs.

While it varies from home to home, US households typically need between 10 and 20 solar panels to fully offset how much electricity they use throughout the year.
