Customer Questions & Answers

Why does this kit cost more than the 400 Watt off-grid solar panel kit? Am I missing something here?

Seems odd to me
Asked by: SolarMatt
It might be that this kit has 1800 watts pure sine wave inverter. I guess.

can this power a large size pond

can this power a large size pond
Asked by: LIsa
There is no way to answer this question without additional information. 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-hours (we need exact daily watt-hour numbers from customers because many standard appliances and devices have widely variable power consumptions). 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. Contact Grape Solar directly for system recommendations, or custom quotes through your local Home Depot Pro Desk.
