kWh per month needed 2. Chose lowest productive month kWh X 31 days = 150 kWh/month kWh/150 kWh (per panel) = 6.66 panels or 7 panels 5. Increase to 8 panels for good measure Solar Panel Array

 If each panel outputs 250 watts, then…  250w X 8 panels = 2000 total watts  If we choose a 24 V charge controller, then…  2000w/24V = or 90 amps  100 amp charge controller needed Charge Controller

 1000 kWh/30 days = 33 kWh X 3 = 99 kWh  99 kWh = 99,000 wh  99,000wh/24V = 4,125 AH  We need (4) 24V, 1100 AH forklift batteries Battery Bank 3 day back-up

Hourly Watt Usage Peek Hour Wattage Use

 The maximum load at any given time is 3,500 watts  An inverter has a 95% efficiency  Therefore, 3,700 watts must be fed into the inverter in order for a 3,500-w output because 3,500/.95 = 3,685-w  (2) 2,500 watt inverters = 5,000 watts DC to AC Inverter

 8 (250-w) solar $1.50/watt = $3,000  1 (100 A) charge controller = $300  4 (1,100 AH) forklift batteries = $ 14,000  2 (2,500-w) Inverters = $3,000  Accessories (cables) = $ 4,000  Total Estimated Cost = $24,300 (40yr payoff)  Estimated Cost Grid-Tied = $10,000 (17yr payoff) Estimated Expense
