15kW solar systems: A great size for large homes & businesses
15kW solar systems are a great system size for homes with high levels of energy consumption or businesses with small to middling energy needs – provided that they have sufficient roof space to install one.Production is 63 kWh per day 22,995 kWh annually.
The battery is capable of holding a little over 15kw of energy which should be enough for overnight for 3 to 4 bedrooms of Air Condioning, some appliances, and lights.
In states where the peak sun hours range between 3.5 and 4 hours(Roatan 4 to 6 hours increase 20%), a solar system with a capacity of 20kW can generate approximately 1,680 kWh of electricity monthly, which averages to about 56 kWh per day. It's important to note that peak sun hours differ from regular daylight hours.
Average kWh usage for a 2,000 square foot home: 1,325 kWh. Average kWh usage for a 3,000 square foot home: 1,840 kWh. Average kWh usage for a 4,000 square foot home: 2.200 kWh. 15KWh system should be good for 2,000sq./feet to 3,000+sq/feet foot home
We try and get you in for $1.25 to $1.50 depending on home size. KWh when most companies charge $2 to $4 per Wh
How Long Will A 15kW Solar System Last? Like most solar systems, the average life span of a 15kW system is 25 to 30 years. According to the National Renewable Energy Laboratory, solar panels face an average efficiency drop of 0.8% each year.
According to the latest estimates, an average American home will use around 30 kilowatt-hours of electricity a day [6]. This means that a 10kW solar array would require just three peak sun hours a day to guarantee an adequate supply of electricity to the owner of an average-sized residence.
