hello,
I am planning an off grid solar installation for a small garage/ garden shed with DC water pump to irrigate a community garden. Looking for some advice as this is my first time dealing with solar. Is my system size ok for what i need or can i downsize? FLA or AGM batteries? I have a budget of $7100 CDN to do this project. I've priced out the components online for about $4600 but not sure what shipping would be like. I'm thinking that should leave me enough for cable, over current protection, ground mount rack. what do you think??
Daily load demands:
DC pump 100 W x 4 hours= 400 Wh
4 inside lights 40 W x 5 hours= 200 Wh
1 outside light 10 W x 12 hours= 120 Wh
1/2 hp overhead garage door 120V, 6A
maybe a radio, cordless drill battery charger, cell charger
I figure 2000 Wh daily should be plenty with room for growth in case i need a 2nd pump.
I am in Central Canada with Avg 5.2 sun hours, and Low 3.2 hours.
2000 Wh x 1.5 (fudge factor)=3000 Wh
3000 Wh / 3.2 sun hours=937.5 W
So.. 1000 Watt solar array should be good. The system will be 24 volt DC. I'm sure this is a little overkill as i will not be needing much power in the winter months
I plan on using 4 grid tie panels x 250 watts each
45 A MPPT charge controller (Morningstar)
1000 W, 24volt, pure sine Inverter
4 x Rolls S-550, 6 volt, 428 AH batteries connected in series.
