What does 37.5 amp hours mean

Asked by: Papa rick
A battery with a capacity of 1 amp-hour should be able to continuously supply a current of 1 amp to a load for exactly 1 hour, or 2 amps for 1/2 hour, or 1/3 amp for 3 hours, etc., before becoming completely discharged. Amp-hours is equal to amps times hours. Divide by amps and you get hours, divide by hours and you get amps. In this scenario, you can run at 37.5 amps for 1 hour before depleting the charge. Or, you can run at 12.5 amps for 3 hours, or 1 amp for 37.5 hours etc..

I have a 3 stable barn that I would like to connect to solar power for the lights and possibly a fan. What size Kit would I need for something like this. The lights would probably be 2 bulb florescent one for each stable.

We'd generally recommend LED lights for uses like this. Assuming ideal panel placement, this 150 watt kit should produce approx. 450 watt-hours of usable power per day (more in summer, less in winter). This would only run a pair of 20 watt CFL lights for around 11 hours a day. For LED lights, you would also need a pure sine wave inverter, like the ones in our 300 and 400 watt kits. To properly size an off-grid system or battery backup system, we would need to know the following: 1. Your estimated daily power usage in watt (we need exact daily watt-hour numbers from customers because many standard appliances and devices have widely variable power consumptions). Energystar’s yearly kWh ratings for fridges and freezers are also helpful to have. 2. Maximum inverter wattage and voltage required – what is the most power, in watts, that the inverter will need to produce, and are you using any 220 volt appliances? 3. Location or zip code of where the panels will be mounted. 4. Months of the year that the system will be needed (winter, summer, year-round, etc.). Please note that battery-based solar requires 2 to 4 times as many panels for winter production.

We have a small storage building 20 x 20, what size panels would be needed for lighting? Not continuous but randomly.

This kit does not include an inverter, we normally recommend the 400 watt kit for LED lighting of indeterminate usage.
