We have 75 solar panels. They are split between our cottage system for 4.2kWp with 17 250w panels. for our main house, we originally installed 40 210w panels and then added an additional 18 250w panels for a total of 58 for a 12.9kWp system.
Our panels are quite a bit lower in power than current ones as we did our system in 2012 and 2014. With current systems the sweet pricing is about 350 watt panels for about $225 each. Higher power panels may be larger and more money per panel.
The dimensions for 350W Panasonic panels are 69.1 x 40.94 (2,829 sq inches) which are a typical size. A typical 4.2kWp system would need 12 panels and take up 236 sq ft, roughly a 20'x 12' area.
Our production in San Diego County with south facing panels has varied between 5,400 to 6,400kWh per year with an average of a bit over 6,000kWp or an average 500kWh. A solar installer can estimate your probable production based on where the panels would be placed (south is best) and whether you have shading issues with trees or whatnot.
Our last systems were under $3/watt or under $13,000 for a 4.2 kWH system less tax credit of 30%, so your net cost would be about $9,000.
ROI varies a lot based on your electric bills. SDG&E has high rates, 40 to 50 cents per kWh depending on tier. If you used 500kWh/month, the cost would be $200/month at 40 cents. Our ROI would be about 45 months. ($9,000/$200).
Where do you live and what price do you pay? In Dallas, TX, the cost is 13 ยข/kilowatt-hour (kWh). 500kWh would cost $65. ROI goes up to 138 months. ROI goes down as your rates increase. Get out your electric bills and the way solar production is done in your state. Our net metering in CA under the old rules allow us to bank production we gave to SDG&E and got credits in months where we used their power. Other states are not giving deal that good.
Solar costs have trended down, so you'd need to get several quotes to get current costs.
